reminder:

1. V2 of tools/xenstore: add some new features to the documentation [1]
Status:  Patch #1 is merged.
According to the discussion in the threads, patch #3 #4 is properly reviewe=

Patch #2 needs a respin and we also need to clarify the integration with
migration/live-update.

2. Patch: x86: enable interrupts around dump_execstate() [2]
Status: Waiting for review.
This is a patch pending for more than 8 months. There has been already a

This is expected and in fact working correctly. We want compiler to warn
us about enum members that are not handled in a switch() statement. The
'default' case exists in some places because we suspect the value might
not have been validated before. For instance:

libxl_disk_backend x = atoi(argv[1]); /* or parse something from XML */

switch(x) {
case LIBXL_DISK_BACKEND_UNKNOWN:
case LIBXL_DISK_BACKEND_PHY:
case LIBXL_DISK_BACKEND_TAP:
case LIBXL_DISK_BACKEND_QDISK:
  // Neither of these might be exectuted ..
default:
  // .. in which case this will.
}


But we are not very consistent in putting 'default' case, sadly.

Ah, I couldn't find the commit in master, and it's simply because it's
not there yet. It's in staging:

https://xenbits.xen.org/gitweb/?p=xen.git;a=commit;f=tools/libs/light/libxl_types.idl;h=66dd1c62b2a3c707bd5c55750d10a8223fbd577f

The patch looks correct. Do you have any estimate when it can be merged
into master? I'm not sure what our, libvirt, rules about xen staging
are, but for qemu we require master (even unreleased yet).

Michal

I'd prefer 1 over 2, but in the unlikely event that 1 ends up unwieldy
I could live with an extensively commented form of 2.

Well... We haven't had any push in libvirt for the past 2 years. So to 
me it shows that nobody really care about the testing done. Therefore, I 
don't see the problem if we don't spot further regressions.

If we don't force push, we have two solutions:
   1) Revert Oleksandr's series
   2) Leave it until we have Osstest fixed *and* Oleksandr's patch 
reached libvirt.

The former is not an option for me, because Oleksandr's series is not at 
fault. So this leave us to 2).

So what's your proposal?

Cheers,

For us this is treated as an error. Is it intended?

If it is, then I think this will be a problem for Xen because it means 
we will always need to fix libvirt before accepting a patch in Xen (see 
more below).

the Xen patch will not be part of master until the patch in libvirt is 
added.

Yes & no, but mostly yes.

You can choose to build with -Werror or not. If building from .git
then it defaults to enabled, but can be disabled if desired.

Generally we want to see errors triggered from new enums arriving,
as it can be a sign that libvirt code needs a semantic change in
order to continue operating correctly.  It isn't always correct
to assume that the 'default' case gives the correct behaviour.

With regards,
Daniel

My worry is while we have a plan to address the libvirt issues, I am not 
confident this could be addressed by Xen 4.17. In particular, Osstest 
has to be fixed and we need a push.

I think this is a bit unfair to block the virtio series on the recent 
lack of investment in libvirt testing.

So if we end up to revert it, this will need to be a block for Xen 4.17.

Cheers,

Actually, as per the advisory it's only the stable trees which want the
respective change committed. Unless I'm unaware of a change in mind.

-Werror shouldn't be enabled when building a package, exactly for this
reason. Header files change and we might get a warning or two when
building a RPM. However, we definitely want to treat warnings as errors
when developing libvirt, i.e. building libvirt from a git repo. That's
why we get -Werror enabled in our CI too.

So we have a chicken egg problem. Xen needs libvirt to compile without
any warning to merge a patch and libvirt wants hypervisors to have the
patch merged first. Well, I think in this case we can make an
"exception". Our demand comes from quite a few cases where we burned
ourselves by merging our portion of a feature before it was merged into
QEMU. And according to Murphy's law, QEMU interface was changed
rendering our patches (now commits) useless. But I believe this is not
the case with xen staging, is it?

BTW: every other package that does switch() over libxl_disk_backend enum
will need this fix.

> Prevent header file from being included more than once by adding ifndef guard.

If such a change is to be made, please also adjust the x86-64 instance of
the header.

However, these headers are inherited from the gnu-efi package, and hence
should see as little customization as possible (you may have noticed
that we didn't even correct the bogus "Module Name:" value in the x86-64
header). While for this particular change I'm not outright opposed, such
an exception to the usual handling would want recording in the
description. Actually - at least the x86-64 header has meanwhile gained
a guard in gnu-efi, so that one likely will want importing instead of
adding a custom one. (I'm looking only at 3.0.14, which I have readily
available - there may be a guard even for aarch64 in an up-to-date
version, so please double check.)

Ok, this makes sense.
The gnu-efi header for x86_64 is guarded with X86_64_EFI_BIND. For 
arm64, efibind header does not have ifndef guard (3.0.14 is the latest tag).
So, I will put X86_64_EFI_BIND and AARCH64_EFI_BIND, in the same way as 
it is done in gnu-efi (that is without following empty line and without 
comment following endif).

I don't think the extra parameter is needed:

You get hold of pdev here, and hence you can take the domain from pdev.

I think this comment wants retaining, as the new one you add is about
a different aspect.

Despite the comment: What guarantees that msix isn't a dangling pointer
at this point? At the very least I think you need to check !pdev->vpci
first. And I'm afraid I don't view "do our best" as good enough here
(considering the patch doesn't carry an RFC tag). And no, I don't have
any good suggestion other than "our PCI device locking needs a complete
overhaul". Quite likely what we need is a refcounter per device, which
- as long as non-zero - prevents removal.

Don't you need to drop the pcidevs lock on this error path?

I'm not convinced the code movement here does us any good. (Same

Simpler

    if ( !pdev || !pdev->vpci )

I guess this is too early and wants to come after ...

... this if, which - even if it doesn't use pdev - still accesses the
device.

Both comments equally apply to vpci_write().

This declaration wants adding alongside the introduction of the
function or, if the series was structured that way, at the time of the
dropping of "static" from the function (which from a Misra perspective
would likely be better).

Subject: [PATCH v2] xen/efi: efibind: fix MISRA C 2012 Directive 4.10 violation
Date: Mon,  1 Aug 2022 15:21:18 +0300
Message-Id: <20220801122118.1673349-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Prevent header file from being included more than once by adding ifndef guard.

In order to be close to gnu-efi code
- for x86_64, use the same guard
- for arm64, that there is no guard in gnu-efi, for consistency,
use a similar format and position to the x86_64 guard

Signed-off-by: Xenia Ragiadakou <burzalodowa@gmail.com>
---

Changes in v2:
- import efibind.h guard from gnu-efi for x86_64
- add a guard for arm64 in a similar, to x86_64, way
- change commit message accordingly

Hello,

a user was making us aware in a bug report that qemu's -soundhw command
line option is deprecated (and apparently going to be gone in the next
version), replaced by some form of -device. libxl_dm.c does not appear
to know of this yet, so I wonder if this isn't something that will want
addressing for 4.17 (and then likely also backporting). Clearly I don't
feel capable myself of making such an adjustment, first and foremost
since I have no clue how to know which variant a given qemu binary is
supporting.

Thanks, Jan

That's correct. Once a patch is merged in staging, we would only revert 
it if there is a breakage that can't be easily solved.

Indeed. From my understanding, there is an expectation that tools built 
on top of libxl may need some update to work on the latest Xen. I will 
let Anthony (one of the tools maintainers to confirm).

This sounds a sensible plan. Anyone from Xen community has an objection 
this with approach?

Subject: [PATCH v10 0/3] Adds starting the idle domain privileged
Date: Mon,  1 Aug 2022 14:49:25 -0400
Message-Id: <20220801184928.28522-1-dpsmith@apertussolutions.com>
X-Mailer: git-send-email 2.20.1

This series makes it so that the idle domain is started privileged under the
default policy, which the SILO policy inherits, and under the flask policy. It
then introduces a new one-way XSM hook, xsm_transition_running, that is hooked
by an XSM policy to transition the idle domain to its running privilege level.

Patch 3 is an important one, as first it addresses the issue raised under an
RFC late last year by Jason Andryuk regarding the awkward entanglement of
flask_domain_alloc_security() and flask_domain_create(). Second, it helps
articulate why it is that the hypervisor should go through the access control
checks, even when it is doing the action itself. The issue at hand is not that
the hypervisor could be influenced to go around these check. The issue is these
checks provides a configurable way to express the execution flow that the
hypervisor should enforce. Specifically with this change, it is now possible
for an owner of a dom0less or hyperlaunch system to express a policy where the
hypervisor will enforce that no dom0 will be constructed, regardless of what
boot construction details were provided to it. Likewise, an owner that does not
want to see dom0less or hyperlaunch to be used can enforce that the hypervisor
will only construct a dom0 domain. This can all be accomplished without the
need to rebuild the hypervisor with these features enabled or disabled.

Changes in v10:
- rewrote patch 3 commit message
- fixed typos in patch 3
- reworked logic in flask_domain_create() to be simpler and not result in
  changing the domain security struct before the access check fails

Changes in v9:
- added missing Rb/Tb to patch 1
- corrected the flask policy macro in patch 2 to allow domain create
- added patch 3 to address allowing the hypervisor create more than 1 domain

Changes in v8:
- adjusted panic messages in arm and x86 setup.c to be less than 80cols
- fixed comment line that went over 80col
- added line in patch #1 commit message to clarify the need is for domain
  creation

Changes in v7:
- adjusted error message in default and flask xsm_set_system_active hooks
- merged panic messages in arm and x86 setup.c to a single line

Changes in v6:
- readded the setting of is_privileged in flask_set_system_active()
- clarified comment on is_privileged in flask_set_system_active()
- added ASSERT on is_privileged and self_sid in flask_set_system_active()
- fixed err code returned on Arm for xsm_set_system_active() panic message

Changes in v5:
- dropped setting is_privileged in flask_set_system_active()
- added err code returned by xsm_set_system_active() to panic message

Changes in v4:
- reworded patch 1 commit messaged
- fixed whitespace to coding style
- fixed comment to coding style

Changes in v3:
- renamed *_transition_running() to *_set_system_active()
- changed the XSM hook set_system_active() from void to int return
- added ASSERT check for the expected privilege level each XSM policy expected
- replaced a check against is_privileged in each arch with checking the return
  value from the call to xsm_set_system_active()

Changes in v2:
- renamed flask_domain_runtime_security() to flask_transition_running()
- added the missed assignment of self_sid

  flask: implement xsm_set_system_active

Subject: [PATCH v10 1/3] xsm: create idle domain privileged and demote after setup

There are new capabilities, dom0less and hyperlaunch, that introduce internal
hypervisor logic, which needs to make resource allocation calls that are
protected by XSM access checks. The need for these resource allocations are
necessary for dom0less and hyperlaunch when they are constructing the initial
domain(s).  This creates an issue as a subset of the hypervisor code is
executed under a system domain, the idle domain, that is represented by a
per-CPU non-privileged struct domain. To enable these new capabilities to
function correctly but in a controlled manner, this commit changes the idle
system domain to be created as a privileged domain under the default policy and
demoted before transitioning to running. A new XSM hook,
xsm_set_system_active(), is introduced to allow each XSM policy type to demote
the idle domain appropriately for that policy type. In the case of SILO, it
inherits the default policy's hook for xsm_set_system_active().

For flask, a stub is added to ensure that flask policy system will function
correctly with this patch until flask is extended with support for starting the
idle domain privileged and properly demoting it on the call to
xsm_set_system_active().

This commit implements full support for starting the idle domain privileged by
introducing a new flask label xenboot_t which the idle domain is labeled with
at creation.  It then provides the implementation for the XSM hook
xsm_set_system_active to relabel the idle domain to the existing xen_t flask
label.

In the reference flask policy a new macro, xen_build_domain(target), is
introduced for creating policies for dom0less/hyperlaunch allowing the
hypervisor to create and assign the necessary resources for domain
construction.

Subject: [PATCH v10 3/3] xsm: refactor flask sid alloc and domain check
Date: Mon,  1 Aug 2022 14:49:28 -0400

The function flask_domain_alloc_security() allocates the security context and
assigns an initial SID for the domain under construction. When it came to SID
assignment of the initial domain, flask_domain_alloc_security() would assign
unlabeled_t. Then in flask_domain_create() it would be switched to dom0_t.
This logic worked under the assumption that the first domain constructed would
be the hypervisor constructing dom0 and all other domains would be constructed
by a toolstack, which would provide a SID. The introduction of dom0less and
subsequently hyperlaunch violates this assumption, as non-privileged domain may
be constructed before the initial domain or no initial domain may be
constructed at all. It is not possible currently for dom0less to express domain
labels in the domain configuration, as such the FLASK policy must employ a
sensible initial SID assignment that can differentiate between hypervisor and
toolstack domain construction.  With the introduction of xenboot_t it is now
possible to distinguish when the hypervisor is in the boot state, and thus any
domain construction happening at this time is being initiated by the
hypervisor.

This commit addresses the above situation by using a check to confirm if the
hypervisor is under the xenboot_t context in flask_domain_alloc_security().
When that is the case, it will inspect the domain's is_privileged field to
determine whether an initial label of dom0_t or domU_t should be set for the
domain. The logic for flask_domain_create() was changed to allow the incoming
SID to override the initial label.

The base policy was adjusted to allow the idle domain under the xenboot_t
context the ability to construct domains of both types, dom0_t and domu_t.

Subject: [PATCH] xen/char: imx-lpuart: Fix MISRA C 2012 Rule 20.7 violation
Date: Tue,  2 Aug 2022 10:54:33 +0300

Content-Transfer-Encoding: 8bit

The macro parameter 'off' is used as an expression and it is good to be
enclosed in parentheses to prevent against unintended expansion.

Subject: [OSSTEST PATCH 0/2] osstest: Fix libvirt build
Date: Tue, 2 Aug 2022 11:26:00 +0100

libvirt now use meson+ninja instead of autoconf, so teach osstest to use that.

I ran a flight with that, here is the result:
"tolerable all pass"

libvirt have switch build system to Meson + Ninja, there is no more
autogen.sh script.

Add missing dependency "libtirpc-dev" and "meson".

libvirt needs at least meson 0.54, the version avaiable in Debian
Buster is too old, but we can install it from backports.

In order to find out if Meson is used or not, we'll check if the
"autogen.sh" script is missing. And in the build dir, we will look for
a "Makefile".

I have forced pushed to the branch smoke using the flight 171899. For 
staging, it looks like the latest flight was testing f732240f, so we 
don't have one with the libvirt patches.

I am hoping the push to the smoke branch will trigger a xen-unstable flight.

Isn't that the exact purpose of 'default' label? If use of 'default'
means "any of the other 5 specific values, but lets save some characters
to not name them explicitly", then IMHO better to name them
explicitly...

I can see a value of -Werror=3Dswitch-enum when adding new (internal) enum
value, to find all the cases where code needs to be adjusted, but even
then a grep is probably sufficient enough. On the other hand, if there
are cases where indeed all the values of (internal API) enum needs to be
handled explicitly, maybe simply omit 'default' label and use
-Werror=3Dswitch?

Anyway, if tracking all the enums values of all the used 3rd-party APIs
is desirable (like, noticing when libxl adds new disk type), then it
probably should be a separate CI job, not the default devel build.
Otherwise breakages like this will happen from time to time, and will
be annoyed for people on involved in specific code part at all.

As a short term fix, maybe Xen's CI can build libvirt with
-Wno-error=3Dswitch-enum?

In general I do not want to include irrelevant changes in my patches.
Also, here, I do not want to drop the parentheses from val because the 
removal of the parentheses
- consists a violation of the rule 20.7
- would allow the following to compile
#define VAL x, y, z);(
imx_lpuart_write(uart, off, VAL)
- is not justifiable (i.e does not fix a bug, does not result in more 
readable code etc)

I understand that the rest of the community does not agree with adding 
parentheses around macro parameters used as function arguments and as 
the right-side operand of the assignment operator, but I consider them 
useful and I do not want to remove them myself. Maybe somebody else from 
the community could do that.

Also, these exceptions would be good to be mentioned in the rules.rst. 
So, that other contributors do not try to fix relevant warnings.

Actually, if an application defines LIBXL_API_VERSION, like libvirt
does, we expect the application to still build against the latest
version of libxl. But I don't think that should prevent us from adding
new enum values.

In order to prepare not allocating or freeing memory from
schedule_cpu_rm(), move this functionality to dedicated functions.

For now call those functions from schedule_cpu_rm().

No change of behavior expected.

Subject: [PATCH 0/3] xen/sched: fix cpu hotplug
Date: Tue,  2 Aug 2022 15:27:44 +0200
Message-Id: <20220802132747.22507-1-jgross@suse.com>
X-Mailer: git-send-email 2.35.3

A recent change in the hypervisor memory allocation framework led to
crashes when unplugging host cpus.

This was due to the (correct) assertion that allocating and freeing
memory is allowed with enabled interrupts only. As the main cpu unplug
operation is done in stop-machine context, this assertion triggers in
debug builds.

Correct that by pre-allocating all needed memory while interrupts are
still on, and free memory after interrupts are enabled again.

Juergen Gross (3):
  xen/sched: introduce cpupool_update_node_affinity()
  xen/sched: carve out memory allocation and freeing from
    schedule_cpu_rm()
  xen/sched: fix cpu hotplug

Date: Tue,  2 Aug 2022 15:27:45 +0200

For updating the node affinities of all domains in a cpupool add a new
function cpupool_update_node_affinity().

In order to avoid multiple allocations of cpumasks split
domain_update_node_affinity() into a wrapper doing the needed
allocations and a work function, which can be called by
cpupool_update_node_affinity(), too.

This will help later to pre-allocate the cpumasks in order to avoid
allocations in stop-machine context.

Subject: [PATCH 3/3] xen/sched: fix cpu hotplug
Date: Tue,  2 Aug 2022 15:36:19 +0200

Cpu cpu unplugging is calling schedule_cpu_rm() via stop_machine_run()
with interrupts disabled, thus any memory allocation or freeing must
be avoided.

Since commit 5047cd1d5dea ("xen/common: Use enhanced
ASSERT_ALLOC_CONTEXT in xmalloc()") this restriction is being enforced
via an assertion, which will now fail.

Before that commit cpu unplugging in normal configurations was working
just by chance as only the cpu performing schedule_cpu_rm() was doing
active work. With core scheduling enabled, however, failures could
result from memory allocations not being properly propagated to other
cpus' TLBs.

Fix this mess by allocating needed memory before entering
stop_machine_run() and freeing any memory only after having finished
stop_machine_run().

Fixes: 1ec410112cdd ("xen/sched: support differing granularity in schedule_cpu_[add/rm]()")

Yes, there's preseed_backports_packages() to install from backports repo
at host/guest installation. But nothing once the OS is already
installed. I thought it would not be a good idea to install meson on
every host.

Would be nice to fix on commit, I guess.

are primarily targetted at libvirt upstream maintainers, so that we
catch problems before code is committed.

Parenthesization won't help against all forms of odd use of parentheses
in macro expansions anyway. Maybe MISRA should (or even does) have a
rule disallowing unbalanced parentheses (an square brackets) in macro
expansions ...

As said before, I very much view too many parentheses as affecting
readability.

This may indeed be the case, while ...

addition of parentheses.

Fair enough; my remark was indeed _only_ a remark - the maintainers
will have to judge in the end.

Subject: [PATCH 0/2] xen: credit2: fix boot hangs if dom0_nodes is used

Content-Transfer-Encoding: 7bit

Currently, if the dom0_nodes parameter is used, to limit the hard or
soft affinity of dom0's vCPUs, the boot hangs. This is because the vCPU
affinity is set in two steps, and is only correct after we've done both.
Credit2, however, manages to see and use the result of the first one and
vCPUs are put on pCPUs where they can't run.

This has been reported here:
https://bugzilla.suse.com/show_bug.cgi?id=1197081

And a fix has been discussed in the thread of this message:
https://lore.kernel.org/xen-devel/e061a647cd77a36834e2085a96a07caa785c5066.camel@suse.com/

The solution adopted in this series is to change the vCPU affinity
setting code in such a way that it happens alltogether and in one place
(patch 2).

While there, make the dom0_vcpus_pin boot parameter more precise, by
making sure that it is applied only to actual dom0's vCPUs, and not to
the vCPUs of the hardware domain, which may or may not be dom0 itself
(patch 2).

Regards

If dom0_vcpus_pin is used, make sure the pinning is only done for
dom0 vcpus, instead of for the hardware domain (which might not be
dom0 at all!).

Subject: [PATCH 2/2] xen/sched: setup dom0 vCPUs affinity only once

Right now, affinity for dom0 vCPUs is setup in two steps. This is a
problem as, at least in Credit2, unit_insert() sees and uses the
"intermediate" affinity, and place the vCPUs on CPUs where they cannot
be run. And this in turn results in boot hangs, if the "dom0_nodes"
parameter is used.

Fix this by setting up the affinity properly once and for all, in
sched_init_vcpu() called by create_vcpu().

Note that, unless a soft-affinity is explicitly specified for dom0 (by
using the relaxed mode of "dom0_nodes") we set it to the default, which
is all CPUs, instead of computing it basing on hard affinity (if any).
This is because hard and soft affinity should be considered as
independent user controlled properties. In fact, if we dor derive dom0's
soft-affinity from its boot-time hard-affinity, such computed value will
continue to be used even if later the user changes the hard-affinity.
And this could result in the vCPUs behaving differently than what the
user wanted and expects.

Fixes: dafd936ddd ("Make credit2 the default scheduler")

Changes from "RFC" [1]:
- Moved handling of the shim case
- Added some more explanation (in particular, about why we stick to all
  CPUs for the soft affinity) in both commit message and comment
- Remove spurious (and non-necessary) credit2 change

Hello Xen-Devel.

I would like to report no compatible firmware for a new laptop Acer Aspire 5=
 A517-52G.

The firmware problem I witness is ACIP errors. Xen does not boot.

These ACIP errors lead to boot into initramfs without mounting storage capab=
ilities.

There is extensive logs, dmesg and attempts I recently send to Xen-Users and=
 got a lot of help and feedback there on a long thread of attempts, but we h=
ave hit a lack of support at this point.

https://lists.xenproject.org/archives/html/xen-users/2022-07/msg00061.html

Can we please have an update to allow this hardware to run Xen.

Kind regards,

Bruno Schroeder=20

Can you please post relevant logs (and other information that may have been
worked out already) here, rather than having everyone who reads this dig
through a pretty long thread? Looking at the first few mails there I can
spot a kernel log, but since you're complaining about Xen boot, I'm missing
the hypervisor log. Or are you talking about Linux not booting when run
under Xen on that machine?

I do see a fair number of ACPI errors in the kernel log - it would then be
helpful to have two logs for comparison, one when the kernel is booted
natively and one when booted under Xen.

Looking at the tail of that log I see an issue with sof-audio-pci, but I
can't seem to be able to associate this with "does not boot". I guess
information about this _might_ be found in the long xen-users thread, but
as said above - please extract relevant information and put it on this
list rather than having everyone go search.

Regards, Jan

Hello Jan.

Thank you.

I=E2=80=99m talking about booting on the host Xen (=E2=80=9CLinux with Xen=E2=
=80=9D) - goes to an initramfs prompt.

I don=E2=80=99t know how to get to this hypervisor log. Maybe not the case a=
s I am attempting the boot on the host linux with Xen. There is no /var/log -=
 only cache and lock

I can list the hard drive partitions under /dev (nvme0n1p1-5), but I cannot m=
ount them. I cannot access a thumb drive either /dev/block, when mounted has=
 two strange symlinks to ../sda1 (8:0 and 1:8). This is a bit frustrating be=
cause it does not allow me to export dmesg or other info.

Im not receiving the error messages on screen before initramfs, they are hid=
den, but I do get this message:

    Gave up waiting for suspend/resume device
     Gave up waiting for root file system device.  Common problems:
Boot args (cat /proc/cmdline) - Check rootdelay=3D (did the system wait long=
 enough?)
Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=3D0123abc does not exist. Dropping to a shell!

On the dmesg, I got the ACPI errors:

ACPI BIOS Error
(bug): Failure creating named ob
I_SB.PCOO.XHCI.RHUB.HS05._UPC], AE ALREADY _EXISTS (Z0211217/dsuloadZ-326)

Repeated several times

Latter on the dmesg I got repeated errors like this:

Generally the hypervisor log is obtained via "xl dmesg" (likely not an
option for you when you end up on an initramfs prompt) or a serial
cable. How do you obtain the kernel log (there was one posted on
xen-users)?

Right - I've seen those. These were why I did ask for a pair of kernel logs
(with and without Xen), to put them side by side and see which of the errors
are common (and hence likely of no interest to resolve your issue).

Besides some of the characters looking scrambled, I can spot nothing like
this in
https://lists.xenproject.org/archives/html/xen-users/2022-07/msg00057.html

Anyway, my request stands: Please post the three named logs here.

On initramfs:

- xl will give me not found - I cannot do xl info or xl dmesg

- I cannot mount any disk, therefore, exporting logs from there has been 
photographing and using OCR then reviewing and correcting - but I guess 
the main difference is ACIP, as I cannot access the disks

I have now booted on kernel 18 to get the kernel boot log for you (the 
one on Xen-user is kernel 10).

There's quite a few places in tools/ where "-include $(DEPS_INCLUDE)" is
missing, so I kind of expect it to be forgotten rather than avoided on
purpose.

Yes, that still works. But I'm not sure why you would ask since the
tools/ build system works this way, execution of make in a subdir
doesn't depends on the execution from the parent dir (it doesn't
depends on anything in the envvar).

Interesting. I would have expected the pre-processor to first expand M 
and then consider wr() is called with 2 parameters.

FWIW, in our case, the compiler is going to throw an error.

My expectation is we would notice that M is missing the parentheses. If 
it is really wanted, the name of the macro should be obvious.

I am struggling to see how this is different from:

#define wr(v) printf("%u\n", v)

If I am not mistaken, you have been arguing against adding the 
parentheses here. So, AFAIU, this means we will need to rely on the 
compiler to notice the extra parameters.

Anyway, I am not against adding the parentheses in your example. 
However, I think we should be consistent how we use them.

Cheers,

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-i386-libvirt            6 libvirt-build            fail REGR. vs. 172073
 build-amd64-libvirt           6 libvirt-build            fail REGR. vs. 172073

    libxl/arm: Create specific IOMMU node to be referred by virtio-mmio device
    
    Reuse generic IOMMU device tree bindings to communicate Xen specific
    information for the virtio devices for which the restricted memory
    access using Xen grant mappings need to be enabled.
    
    Insert "iommus" property pointed to the IOMMU node with "xen,grant-dma"
    compatible to all virtio devices which backends are going to run in
    non-hardware domains (which are non-trusted by default).
    
    Based on device-tree binding from Linux:
    Documentation/devicetree/bindings/iommu/xen,grant-dma.yaml
    
    The example of generated nodes:
    
    xen_iommu {
        compatible = "xen,grant-dma";
        #iommu-cells = <0x01>;
        phandle = <0xfde9>;
    };
    
    virtio@2000000 {
        compatible = "virtio,mmio";
        reg = <0x00 0x2000000 0x00 0x200>;
        interrupts = <0x00 0x01 0xf01>;
        interrupt-parent = <0xfde8>;
        dma-coherent;
        iommus = <0xfde9 0x01>;
    };
    
    virtio@2000200 {
        compatible = "virtio,mmio";
        reg = <0x00 0x2000200 0x00 0x200>;
        interrupts = <0x00 0x02 0xf01>;
        interrupt-parent = <0xfde8>;
        dma-coherent;
        iommus = <0xfde9 0x01>;
    };

    libxl: Introduce basic virtio-mmio support on Arm
    
    This patch introduces helpers to allocate Virtio MMIO params
    (IRQ and memory region) and create specific device node in
    the Guest device-tree with allocated params. In order to deal
    with multiple Virtio devices, reserve corresponding ranges.
    For now, we reserve 1MB for memory regions and 10 SPIs.
    
    As these helpers should be used for every Virtio device attached
    to the Guest, call them for Virtio disk(s).
    
    Please note, with statically allocated Virtio IRQs there is
    a risk of a clash with a physical IRQs of passthrough devices.
    For the first version, it's fine, but we should consider allocating
    the Virtio IRQs automatically. Thankfully, we know in advance which
    IRQs will be used for passthrough to be able to choose non-clashed
    ones.

    libxl: Add support for Virtio disk configuration
    
    This patch adds basic support for configuring and assisting virtio-mmio
    based virtio-disk backend (emulator) which is intended to run out of
    Qemu and could be run in any domain.
    Although the Virtio block device is quite different from traditional
    Xen PV block device (vbd) from the toolstack's point of view:
     - as the frontend is virtio-blk which is not a Xenbus driver, nothing
       written to Xenstore are fetched by the frontend currently ("vdev"
       is not passed to the frontend). But this might need to be revised
       in future, so frontend data might be written to Xenstore in order to
       support hotplugging virtio devices or passing the backend domain id
       on arch where the device-tree is not available.
     - the ring-ref/event-channel are not used for the backend<->frontend
       communication, the proposed IPC for Virtio is IOREQ/DM
    it is still a "block device" and ought to be integrated in existing
    "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
    logic to deal with Virtio devices as well.
    
    For the immediate purpose and an ability to extend that support for
    other use-cases in future (Qemu, virtio-pci, etc) perform the following
    actions:
    - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
      that in the configuration
    - Introduce new disk "specification" and "transport" fields to struct
      libxl_device_disk. Both are written to the Xenstore. The transport
      field is only used for the specification "virtio" and it assumes
      only "mmio" value for now.
    - Introduce new "specification" option with "xen" communication
      protocol being default value.
    - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
      one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
    
    An example of domain configuration for Virtio disk:
    disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
    
    Nothing has changed for default Xen disk configuration.
    
    Please note, this patch is not enough for virtio-disk to work
    on Xen (Arm), as for every Virtio device (including disk) we need
    to allocate Virtio MMIO params (IRQ and memory region) and pass
    them to the backend, also update Guest device-tree. The subsequent
    patch will add these missing bits. For the current patch,
    the default "irq" and "base" are just written to the Xenstore.
    This is not an ideal splitting, but this way we avoid breaking
    the bisectability.

This patch is correct and it fixes the issue which is meant to fix.

Dropping the parentheses from the single use of "val" is not something
currently covered by our coding style document or by MISRA, so it is
normal that we are going to get a variety of opinions and preferences on
it.

I think it is better to avoid asking for changes not currently in
CODING_STYLE and docs/misra. It is less work for both reviewers and
contributors to add the rule to the coding style first, then ask for
changes.

So my preference is to keep this patch as is (regardless of what we are
going to do with "val"):

Reviewed-by: Stefano Stabellini <sstabellini@kernel.org>


But I am happy to add the "avoid too many parenthesis" point to the list
of coding style things to discuss. FYI I paused the MISRA C discussion
meetings so that we can make some progress on fixing violations, but I
plan to resume those meetings in a month or two.

Thank you for your reply. I will seriously consider contributing
platform specific drivers. Currently, I make a sample usage by applying thi=

for readability and understandability.
These patches are just one of my suggestion. So feel free to reject it.

Subject: [PATCH v2 2/2] xen: remove init_constructors out of start_xen

This patch removed init_constructors from start_xen
by using __late_initcall.
It can be applied to other init functions in start_xen
so that only main init functions are included in there.

To use __late_initcall, the format of a function should
be changed according to initcall. Thus, the return type
of init_constructors function is changed in this patch.

Oh, I wasn't even aware of this as a general feature in tools/. Is
this going to survive your rework to use non-recursive makefiles?

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

I very specifically disagree with this statement: Attempts to add
text there have been ignored altogether, i.e. have not even been
seen worth a comment against the clarification and/or addition. I
have therefore given up to propose changes to this document, and
I'm also not going to suggest to anyone to make any attempt up and
until I see movement on the adjustment proposals already pending
(the two of them that I can easily locate for now over 2 years,
and iirc there were more which predate our switching of email
systems and which hence I wouldn't have in my outbox anymore).

As expected - you'd have to handcraft xl and ints libraries into the
image.

Oh, I see. I was kind of expecting (hoping) you might be able to
export the logs via, say, a USB key.

At the first glance - similar ACPI errors, and a similar issue with
loading sound firmware. Using two different kernels won't really
lend itself for direct comparison, though. At the moment I don't see
a good way forward here as long as not even proper logs can be
obtained: It may be necessary to add debugging code, the output of
which would also need collecting. But maybe someone else sees a
viable route to help you ...

Oh, actually upon looking again I spotted something:

nvme nvme0: pci function 10000:e1:00.0

Note the wider-than-16-bits segment number. Which, afaict, is an effect of
using the Volume Management Device:

vmd 0000:00:0e.0: PCI host bridge to bus 10000:e0

You may want to go through firmware setup options to see whether there's a
way to disable it / its use. Neither Xen nor the Dom0 Linux kernel (i.e.
when run under Xen) have been enabled so far to make this work (and, from
inspection quite a while back, the kernel implementation, during its design,
not having considered the possibility of running on a type-1 hypervisor will
likely make adding support, well, interesting).

The macro parameters 'off' and 'uart' are used as expressions and it is
good to be enclosed in parentheses to prevent against unintended expansion.

For the 'uart' case, in mvebu3700_write(), correct the second parentheses
that seems to have been accidently misplaced.

... you're changing the point in time when the constructors are called.
This _may_ be fine, but the reason(s) why it is would need supplying in
the description.

Instead of splitting the function, did you consider using
cond_zalloc_cpumask_var() here, thus allowing (but not requiring)
callers to pre-allocate the masks? Would imo be quite a bit less
code churn (I think).

Wouldn't this be a nice general helper function, also usable from
outside of this CU?

As a nit - right now the only caller treats the return value as boolean,
so perhaps the function better would return bool?

Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-6.0-rc1-tag

xen: branch for v6.0-rc1

It contains:

- a series fine tuning virtio support for Xen guests, including removal
  the now again unused "platform_has()" feature.

- a fix for host admin triggered reboot of Xen guests

- a simple spelling fix

Thanks.

Juergen

Hmm, the real fix imo would be to add $(PYTHON), just like we use

certainly wouldn't mind the mode change, but that would then only
be for cosmetic reasons.)

Please avoid top-posting. Also, I would suggest to read through [1] to 
check how patch series should be submitted. For instance...

A new version of a series is usually sent as a separate thread rather 
than in-reply to the previous version.

Furthermore, as there is 2 patches, you need to provide a cover letter 
(even it doesn't contain much).

Lastly (process wise), please provide a list of changes made in v2. I 
tend to prefer per-patch changelog, but one in the cover letter would 
also work.

I think this is a bit too vague. AFAIU, you want late_initcall() to 
happen *after* all the domains have been created but *before* they are 
unpaused. Is that correct?

 From the previous discussion, I saw you said you have drivers needing 
to call initlate. Could you briefly explain why they can't be called in 
initcall?

IIUC, you are saying that do_late_initcalls() was introduced for 
prioritization purpose. But then, there are also a difference in 
behavior (initcalls happens before creating the domains whereas late 
happens after).

Therefore, if the priority is the only reasons, then I think we should 
introduce priority within the initcalls.

It would be preferable if the call is done roughly at the same place on 
all architecture. So if it easier for a developer to know when this will 
be called (e.g. just after serial_endboot()).

If you need to call the function at the different place, then I think 
this ought to be explained.

Hmm, I see there are quite a few callers (so there would be code churn
elsewhere). But I don't think the struct would need making globally
visible - the majority of callers could simply pass NULL, making the
function use a local instance of the struct instead. Personally I think
that would still be neater than having a _noalloc-suffixed variant of a
function (and specifically in this case also with an already long name).
But I guess this is then up to you / the scheduler maintainers.

I was actually thinking the other way around - the clearing of the masks
might better move into what is domain_update_node_affinity_noalloc() in
this version of the patch, so the helper could continue to use the non-
clearing allocations.

While code is supposedly only being moved, I still question this not
being "unsigned int", the more that sr->granularity is "unsigned int"
as well. (Same then for the retained instance ofthe variable in the
original function.) Of course the loop in the error path then needs
writing differently.

Afaict xmalloc_flex_struct() would do here, as you fill all fields.

At least from an abstract perspective, doesn't reading fields from
sr require the RCU lock to be held continuously (i.e. not dropping
it at the end of this function and re-acquiring it in the caller)?

This conditional is lost afaict, resulting in potentially wrong behavior
in the new helper. Considering its purpose I expect there's a guarantee
that the field's value can never be zero, but then I guess an ASSERT()
would be nice next to the potentially problematic uses in the helper.

Stefano is meant to look after the backports so I have held off doing 
them (although I don't really want to take that responsability :)). 
Below a potential list:

- af570d1c90f1 "xen/arm: Advertise workaround 1 if we apply 3"
- 95604873ccf5 "arm/its: enable LPIs before mapping the collection table"
- 407b13a71e32 "xen/arm: p2m don't fall over on FEAT_LPA enabled hw"
- aa1cba100bff "xen/arm: Avoid overflow using MIDR_IMPLEMENTOR_MASK"
- ee11f092b515 "xen: arm: Don't use stop_cpu() in halt_this_cpu()"
- 6655eb81092a "xen/arm: avoid overflow when setting vtimer in context

- 25424d1a6b7b "xen/arm: head: Add missing isb after writing to

- 800f21499e0e "arm/vgic-v3: fix virq offset in the rank when storing

I agree with Julien we can implement the something similar to is_memory_hol=

that will check that the bar is within the bridge ranges.

If you are okay you can discard this patch in next version of the series an=

for review.

When you mentioned your plan, I was actually envisioning a slightly
different model: Instead of doing the allocation at CPU_DOWN_PREPARE,
allocate a single instance during boot, which would never be freed.
Did you consider such, and it turned out worse? I guess the main
obstacle would be figuring an upper bound for sr->granularity, but
of course schedule_cpu_rm_alloc(), besides the allocations, also
does quite a bit of filling in values, which can't be done up front.

I don't think the conditional is really needed - it merely avoids two
xfree(NULL) invocations at the expense of readability here. Plus -
wouldn't this better be part of ...

... this anyway?

Ah - here you actually want a non-boolean return value. No need to
change that then in the earlier patch (albeit of course a change
there could be easily accommodated here).

Along the lines of the earlier comment this 2nd allocation may also
want to move into schedule_cpu_rm_alloc(). If other users of the
function don't need the extra allocations, perhaps by adding a bool
parameter.

Subject: [PATCH v2 0/2] xen: credit2: fix boot hangs if dom0_nodes is used
From: Dario Faggioli <dfaggioli@suse.com>

Take 2 of this series. I think I've addressed Jan's comments. v1 was
Message-id: <165944775952.3531.14547627248752689801.stgit@tumbleweed.Wayrath>

Currently, if the dom0_nodes parameter is used, to limit the hard or
soft affinity of dom0's vCPUs, the boot hangs. This is because the vCPU
affinity is set in two steps, and is only correct after we've done both.
Credit2, however, manages to see and use the result of the first one and
vCPUs are put on pCPUs where they can't run.

This has been reported here:
https://bugzilla.suse.com/show_bug.cgi?id=1197081

And a fix has been discussed in the thread of this message:
https://lore.kernel.org/xen-devel/e061a647cd77a36834e2085a96a07caa785c5066.camel@suse.com/

The solution adopted in this series is to change the vCPU affinity
setting code in such a way that it happens alltogether and in one place
(patch 2).

While there, make the dom0_vcpus_pin boot parameter more precise, by
making sure that it is applied only to actual dom0's vCPUs, and not to
the vCPUs of the hardware domain, which may or may not be dom0 itself
(patch 2).

Regards

      xen: sched: dom0_vcpus_pin should only affect dom0

Subject: [PATCH v2 2/2] xen/sched: setup dom0 vCPUs affinity only once

Right now, affinity for dom0 vCPUs is setup in two steps. This is a
problem as, at least in Credit2, unit_insert() sees and uses the
"intermediate" affinity, and place the vCPUs on CPUs where they cannot
be run. And this in turn results in boot hangs, if the "dom0_nodes"
parameter is used.

Fix this by setting up the affinity properly once and for all, in
sched_init_vcpu() called by create_vcpu().

Note that, unless a soft-affinity is explicitly specified for dom0 (by
using the relaxed mode of "dom0_nodes") we set it to the default, which
is all CPUs, instead of computing it basing on hard affinity (if any).
This is because hard and soft affinity should be considered as
independent user controlled properties. In fact, if we dor derive dom0's
soft-affinity from its boot-time hard-affinity, such computed value will
continue to be used even if later the user changes the hard-affinity.
And this could result in the vCPUs behaving differently than what the
user wanted and expects.

Fixes: dafd936dddbd ("Make credit2 the default scheduler")

Changes from v1:
- Fixed hash of the referred commit in changelog
- check domain_id to be 0, for properly identifying dom0

Changes from "RFC" [1]:
- Moved handling of the shim case
- Added some more explanation (in particular, about why we stick to all
  CPUs for the soft affinity) in both commit message and comment
- Remove spurious (and non-necessary) credit2 change

Yes. Executing `make` in any subdir will still works. It should be even
better than the current situation, even in a fresh clone, we could
simply run `./configure && make -C subdir` and make will make everything
needed, that is probably the "include/" dir and the "libs/" if they are
needed by anything in that subdir.

At the moment, one can run ./configure then `make -C tools/include` and
`make -C tools/libs` and probably run make in most subdir without having
to wait for a long run of `make build-tools`.

Cheers,

I think it would be better with $(filter-out,):

    ifeq (,$(filter-out %clean,$(MAKECMDGOALS)))

Also, don't hide this rule, instead, hide the "-include", there is no
need to have make waist time trying to find a rule to make
".ocamldep.make" and failing when not needed.

Should we have is "Signed-off-by" tag then? Also he might be the author
of the patch, isn't it?

Should this two new "dune*" files be added to MAINTAINERS in the OCAML
section?

Is this file going to be in many subdirectory or just in tools/ ? You can
prepend a slash to tell git to ignore this file only in this directory.

> +_build/

Is this where dune is going to do out-of-tree build by default? Also, is
this only going to be in tools/_build/ ?

That last line doesn't seems related to dune, why is it in this patch?

Also, can you sort the lines in this .gitignore?

Thanks,

Subject: [PATCH v2] tools: use $(PYTHON) to call cppcheck tools
Date: Wed,  3 Aug 2022 12:57:02 +0100
Message-Id: <708f00303d1c370622707866d41a868425a17324.1659527529.git.bertrand.marquis@arm.com>
X-Mailer: git-send-email 2.25.1

When calling python tools to convert misra documentation or merge
cppcheck xml files, use $(PYTHON).
While there fix misra document conversion script to be executable.

Fixes: 57caa53753 (xen: Add MISRA support to cppcheck make rule)
Fixes: 43aa3f6e72 xen/build: Add cppcheck and cppcheck-html make rules
Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
---
Changes in v2:
- use $(PYTHON) in Makefile to call convert misra doc script
- use $(PYTHON) in Makefile to call merge cppcheck script
- change title as mode change is only a small part
- add "fixes" for the merge change

Hmm, this sounds like I should be reverting the commit?

Subject: [PATCH v3 0/5] tools/xenstore: add some new features to the documentation
Date: Wed,  3 Aug 2022 13:59:45 +0200
Message-Id: <20220803115950.10904-1-jgross@suse.com>

In the past there have been spotted some shortcomings in the Xenstore
interface, which should be repaired. Those are in detail:

- Using driver domains for large number of domains needs per domain
  Xenstore quota [1]. The feedback sent was rather slim (one reply),
  but it was preferring a new set of wire commands.

- XSA-349 [2] has shown that the current definition of watches is not
  optimal, as it will trigger lots of events when a single one would
  suffice: for detecting new backend devices the backends in the Linux
  kernel are registering a watch for e.g. "/local/domain/0/backend"
  which will fire for ANY sub-node written below this node (on a test
  machine this added up to 91 watch events for only 3 devices).
  This can be limited dramatically by extending the XS_WATCH command
  to take another optional parameter specifying the depth of
  subdirectories to be considered for sending watch events ("0" would
  trigger a watch event only if the watched node itself being written).

- New features like above being added might make migration of guests
  between hosts with different Xenstore variants harder, so it should
  be possible to set the available feature set per domain. For socket
  connections it should be possible to read the available features.

- The special watches @introduceDomain and @releaseDomain are rather
  cumbersome to use, as they only tell you that SOME domain has been
  introduced/released. Any consumer of those watches needs to scan
  all domains on the host in order to find out the domid, causing
  significant pressure on the dominfo hypercall (imagine a system
  with 1000 domains running and one domain dying - there will be more
  than 1000 watch events triggered and 1000 xl daemons will try to
  find out whether "their" domain has died). Those watches should be
  enhanced to optionally be specific to a single domain and to let the
  event carry the related domid.

As some of those extensions will need to be considered in the Xenstore
migration stream, they should be defined in one go (in fact the 4th one
wouldn't need that, but it can easily be connected to the 2nd one).
As such extensions need to be flagged in the "features" in the ring

Add the documentation of the new commands/features.

I was going to force this flight because of the libvirt issues. But...

>   test-amd64-amd64-xl-qemuu-debianhvm-i386-xsm 12 debian-hvm-install fail REGR. vs. 172073

... this is not a test related to libvirt. Can one of the x86 folks 
advise whether the issue is benign?

Cheers,

Nit: These two titles would want expressing consistently. If I
end up committing this, I'll try to remember to adjust.

There are actually a few issues with the Fixes tags. From the doc [1] :
   - the sha1 should be 12 characters (rather than 10)
   - the format should be:
       Fixes: <comidid> ("Commit title")

Cheers,

Well, it's not exactly an issue as there isn't any alternative rules,

If Jan doesn't want to fix it on commit. Then I would be happy to do it.

Potentially, but ./configure doesn't have access to the list of
xen libraries, so I'm not sure it would be a good idea.

You've added dune-workspace* to .gitignore in the previous patch, should
the addition be done in this patch instead? (Also feel free to create
"tools/ocaml/.gitignore".

No, do not run ./configure from the makefile. ./configure needs to be
run before running make.

> +	$(MAKE) -C tools/libs V=

No, do not start a build of the libraries from the root make file. If a
user were to run `make build-tools-oxenstored-prepare build-tools`, we
would end up with 2 make running `make -C tools/libs` concurrently which
isn't going to end well.

Please, don't change those options, I don't think these options belong
to a Makefile.

That's why you do -Lpath -Wl,-rpath=path. Would the files generated in
tools/pkg-config/ would be useful for dune?

LD_LIBRARY_PATH is kind of expected to run binaries, but how is
LIBRARY_PATH used, and by which process?

Do you need all those libs? Can't you instead list the library needed
or use the value listed in "tools/libs/uselibs.mk" ?

I think it would be much better to tell the user to run clean themself,
like we do in the hypervisor tree when trying to do an out-of-tree
build. See rule "outputmakefile" in "xen/Makefile".

I think make should fail if "Paths.mk" doesn't exist, could you remove
the dash ? (Also, at this point, "Paths.mk" should already exist because
Rules.mk checks that ./configure has run.)

Each option here could be on there own line, for clarity.

Subject: [PATCH v11] xsm: refactor flask sid alloc and domain check
Date: Wed,  3 Aug 2022 11:17:41 -0400
Message-Id: <20220803151741.7826-1-dpsmith@apertussolutions.com>
X-Mailer: git-send-email 2.20.1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The function flask_domain_alloc_security() allocates the security context and
assigns an initial SID for the domain under construction. When it came to SID
assignment of the initial domain, flask_domain_alloc_security() would assign
unlabeled_t. Then in flask_domain_create() it would be switched to dom0_t.
This logic worked under the assumption that the first domain constructed would
be the hypervisor constructing dom0 and all other domains would be constructed
by a toolstack, which would provide a SID. The introduction of dom0less and
subsequently hyperlaunch violates this assumption, as non-privileged domain may
be constructed before the initial domain or no initial domain may be
constructed at all. It is not possible currently for dom0less to express domain
labels in the domain configuration, as such the FLASK policy must employ a
sensible initial SID assignment that can differentiate between hypervisor and
toolstack domain construction.  With the introduction of xenboot_t it is now
possible to distinguish when the hypervisor is in the boot state, and thus any
domain construction happening at this time is being initiated by the
hypervisor.

This commit addresses the above situation by using a check to confirm if the
hypervisor is under the xenboot_t context in flask_domain_alloc_security().
When that is the case, it will inspect the domain's is_privileged field to
determine whether an initial label of dom0_t or domU_t should be set for the
domain. The logic for flask_domain_create() was changed to allow the incoming
SID to override the initial label.

The base policy was adjusted to allow the idle domain under the xenboot_t
context the ability to construct domains of both types, dom0_t and domu_t.

Split out from series "Adds starting the idle domain privileged", earlier patches
from series have been committed.

Changes in v11:
- put back dom0_created variable in flask_domain_create() to ensure the
  enforcement that dom0_t is a singleton label

Changes in v10:
- rewrote commit message
- fixed typos
- reworked logic in flask_domain_create() to be simpler and not result in
  changing the domain security struct before the access check fails

That would be fine.

:-), it doesn't looks like the others ./configure have much dependencies
that aren't also needed in tools, so I don't think it make sense to
avoid the toplevel ./configure at this time. We don't really test
running ./configure in only a subsystem so it's probably best to avoid
documenting it. You can always run `./configure --disable-{xen,docs}` to
run the minimum amount of ./configure.

Easy:
    ./configure && make -C tools/include && make -C tools/libs
Hopefully, this would be enough, will keep working for a while. But it
might break. (I would try to keep that command above working but who
knows if change would be needed)

Non-recursive makefiles, I want that as well!! :-)
I'm working on it:
    [XEN PATCH v3 00/25] Toolstack build system improvement, toward non-recursive makefiles
    https://lore.kernel.org/all/20220624160422.53457-1-anthony.perard@citrix.com/
But that's going to take a while. There's till a lot of patches that I
haven't posted yet.

I'm not sure, these are just kind of "optimisation" to workaround our
build system. It could easily apply to many subdir in tools/, but
there's no documentation for it. One could run make in most subdir after
just running `./configure && make -C tools/include && make -C
tools/libs`, but I don't think we should document it. As documenting it
makes it harder to make changes if needed.

Use the "alias" built-in from your shell, if you want to have -j$(nproc)
added to you `make` commands.

There's .bashrc or .zshrc or ..., make doesn't need to know. ;-)

Use of $LD_LIBRARY_PATH is fine, it's already used in several places. I
guess "-Wl,-rpath" could be used instead but is probably best to avoid as
not normally needed.

Now about link time, normally we seem to have the full path to the
library we want to link to, or we provide '-L' via pkg-config file.
Then, when a library is links against another one, and the linker wants
to know where this library is, we use "-rpath-link" and I might be
wrong but this probably doesn't add anything in the library.

It seems to me that $LIBRARY_PATH might be useful for external project,
we would want to links against the libraries that aren't yet installed
on the system. But event that isn't needed as we generates
"tools/pkg-config/" which have the needed flags. We use that for
building qemu for example, and I think qemu's configure can make use of
that.

I'd mostly like to avoid $(wildcard ) if possible.

The comment already speak detecting unclean source tree, but I guess it
probably still run `make clean` even if clean.

The toolstack build system doesn't support out-of-tree build. But my
work on non-recursive makefile would potentially allow that.

Having the dune stuff not been run when running for example `make
build-tools` is probably going to make this kind of things awkward at
first. That is both dune and make buids could be use in parallel (not
necessary at the same time) if the developer doesn't pay attention. I
guess later if could have something like `./configure
--enable-ocaml-dune`, there will be less risk of having the make build
ocaml stuff instead of dune as intended by a developer. Also, this could
allow to test dune build in our CI.

Cheers,

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

commit 89fe6d0edea841d1d2690cf3f5173e334c687823
Author: Edwin Török <edvin.torok@citrix.com>
Date:   Wed Aug 3 12:39:13 2022 +0200

    x86/msr: fix X2APIC_LAST
    
    The latest Intel manual now says the X2APIC reserved range is only
    0x800 to 0x8ff (NOT 0xbff).
    This changed between SDM 68 (Nov 2018) and SDM 69 (Jan 2019).
    The AMD manual documents 0x800-0x8ff too.
    
    There are non-X2APIC MSRs in the 0x900-0xbff range now:
    e.g. 0x981 is IA32_TME_CAPABILITY, an architectural MSR.
    
    The new MSR in this range appears to have been introduced in Icelake,
    so this commit should be backported to Xen versions supporting Icelake.

    tools/libxl: env variable to signal whether disk/nic backend is trusted
    
    Introduce support in libxl for fetching the default backend trusted
    option for disk and nic devices.
    
    Users can set LIBXL_{DISK,NIC}_BACKEND_UNTRUSTED environment variable
    to notify libxl of whether the backends for disk and nic devices
    should be trusted.  Such information is passed into the frontend so it
    can take the appropriate measures.
    
    This is part of XSA-403.

Subject: [PATCH V3 0/6] Virtio toolstack support for I2C and GPIO on Arm
Date: Thu,  4 Aug 2022 12:31:48 +0530
Message-Id: <cover.1659596139.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Hello,

This patchset adds toolstack support for I2C and GPIO virtio devices. This is
inspired from the work done by Oleksandr for the Disk device.

This is developed as part of Linaro's Project Stratos, where we are working
towards Hypervisor agnostic Rust based backend [1].

This is based of origin/staging (commit 01ca29f0b17a ("sched: dom0_vcpus_pin
should only affect dom0")) which already has Oleksandr's patches applied.

V2->V3:
- Rebased over latest tree and made changes according to changes in Oleksandr's
  patches from sometime back.
- Minor cleanups.

V1->V2:
- Patches 3/6 and 4/6 are new.
- Patches 5/6 and 6/6 updated based on the above two patches.
- Added link to the bindings for I2C and GPIO.
- Rebased over latest master branch.


Thanks.

Subject: [PATCH V3 1/6] libxl: Add support for Virtio I2C device
Date: Thu,  4 Aug 2022 12:31:49 +0530
Message-Id: <6cd6ca9d72d4f844e8a007b687e28f49301fae03.1659596139.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
In-Reply-To: <cover.1659596139.git.viresh.kumar@linaro.org>
References: <cover.1659596139.git.viresh.kumar@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-i2c backend (emualator) which is intended to run out of
Qemu and could be run in any domain.

An example of domain configuration for Virtio I2c:
i2c = [ "" ]

Please note, this patch is not enough for virtio-i2c to work on Xen
(Arm), as for every Virtio device we need to allocate Virtio MMIO params
(IRQ and memory region) and pass them to the backend, also update Guest
device-tree. A subsequent patch will add these missing bits. For the
current patch, the default "irq" and "base" are just written to the
Xenstore.

Subject: [PATCH V3 2/6] libxl: Add support for Virtio GPIO device
Date: Thu,  4 Aug 2022 12:31:50 +0530
Message-Id: <ef815025eda7018cd713f13eb0d6a540e9deae9f.1659596139.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
In-Reply-To: <cover.1659596139.git.viresh.kumar@linaro.org>
References: <cover.1659596139.git.viresh.kumar@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-gpio backend (emualator) which is intended to run out of
Qemu and could be run in any domain.

An example of domain configuration for Virtio Gpio:
gpio = [ "" ]

Please note, this patch is not enough for virtio-gpio to work on Xen
(Arm), as for every Virtio device we need to allocate Virtio MMIO params
(IRQ and memory region) and pass them to the backend, also update Guest
device-tree. A subsequent patch will add these missing bits. For the
current patch, the default "irq" and "base" are just written to the
Xenstore.

make_virtio_mmio_node() creates the DT node for simple MMIO devices
currently, i.e. the ones that don't require any additional properties.

In order to allow using it for other complex device types, split the
functionality into two, one where the fdt node isn't closed and the
other one to create a simple DT node.

This code tries to store -EFAULT in an unsigned int.  The
xenbus_file_read() function returns type ssize_t so the negative value
is returned as a positive value to the user.

This change forces another change to the min() macro.  Originally, the
min() macro used "unsigned" type which checkpatch complains about.  Also
unsigned type would break if "len" were not capped at MAX_RW_COUNT.  Use
size_t for the min().  (No effect on runtime for the min_t() change).

Hi there,

Now I am working on Ampere Altra SoC platform, with Xen (4.16) and Linux
kernel (5.15.23).

I observed a warning is reported by Linux kernel in the booting flow:

Looked into the code, the GICv3 driver tries to create persistent
reservations for pending pages, and the persistent reservation table
can be used by kexec/kdump.  For the persistent reservations, it
relies on MEMRESERVE EFI configuration table, but this table is not
supported by xen.efi, I think this is the reason for the above oops.

I checked that if I boot a host Linux (without Xen), then the EFI has
provided MEMRESERVE configuration table, I can get below log:

  #  dmesg | grep MEMRESERVE
  [    0.000000] efi: TPMFinalLog=0x807f9ef0000 ACPI 2.0=0x807fa0d0018 ... MEMRESERVE=0x807f8141e98

Just want to confirm, is anyone working on enabling MEMRESERVE EFI
configuration table for Xen?  And welcome any comments and
suggestions!

Thanks,
Leo

Subject: [PATCH] xen/compiler: Fix MISRA C 2012 Rule 20.7 violation
Date: Thu,  4 Aug 2022 15:29:07 +0300
Message-Id: <20220804122907.1821730-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

In __must_be_array(), the macro parameter 'a' is used as expression and
therefore it is good to be enclosed in parentheses to prevent against
unintended expansions.

Subject: [PATCH v2] xen/hypfs: check the return value of snprintf to avoid leaking stack accidently
Date: Thu,  4 Aug 2022 15:47:36 +0300
Message-Id: <20220804124736.1827246-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The function snprintf() returns the number of characters that would have been
written in the buffer if the buffer size had been sufficiently large,
not counting the terminating null character.
Hence, the value returned is not guaranteed to be smaller than the buffer size.
Check the return value of snprintf to prevent leaking stack contents to the
guest by accident.

Also, for debug builds, add an assertion to ensure that the assumption made on
the size of the destination buffer still holds.

Signed-off-by: Xenia Ragiadakou <burzalodowa@gmail.com>

Changes in v2:
- add ASSERT_UNREACHABLE()
- update commit message accordingly

I have to admit that I'm always puzzled when seeing such - why not

#define DBC_TRB_RING_CAP (DBC_TRB_PER_PAGE << DBC_TRB_RING_ORDER)

?

I'm afraid I still don't see why the static page this field is being
initialized with is necessary. Can't you have a static variable (of
some struct type) all pre-filled at build time, which you then apply
virt_to_maddr() to in order to fill the respective dbc_ctx fields?
That struct will be quite a bit less than a page's worth in size.

If you build the file with -fshort-wchar, you may even be able to
use easy to read string literals for the initializer.

While there may be an assumption of DBC_PAGE_SIZE == PAGE_SIZE, the
constant used here clearly needs to be PAGE_SIZE, as that's the unit
set_fixmap_nocache() deals with.

Before actually using the address to map the MMIO you will want to make
somewhat sure firmware did initialize it: The EHCI driver checks for
all zeroes or all ones in the writable bits.

Can't this be const void * (and probably wants to also use __iomem),
avoiding the cast here, ...

... here, ...

... and here (if actually using the local variable you've got).

Hmm, is this comment telling me that this driver is an output-only one?
Or is it simply that input doesn't use this code path?

... this missing blanks added here.

This duplicates what ehci-dbgp.c already has. I guess we can live with
it for now and de-duplicate later, but it's still a little odd. In any
even please move the blank line up be a line, so that string_param()
and its referenced array are kept together.

Why? dbc_uart is a static variable, and hence already zero-initialized.

Subject: [PATCH v3] xen/hypfs: check the return value of snprintf to avoid leaking stack accidently
Date: Thu,  4 Aug 2022 16:30:58 +0300
Message-Id: <20220804133058.1832142-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The function snprintf() returns the number of characters that would have been
written in the buffer if the buffer size had been sufficiently large,
not counting the terminating null character.
Hence, the value returned is not guaranteed to be smaller than the buffer size.
Check the return value of snprintf to prevent leaking stack contents to the
guest by accident.

Also, for debug builds, add an assertion to ensure that the assumption made on
the size of the destination buffer still holds.

Changes in v2:
- add ASSERT_UNREACHABLE()
- update commit message accordingly

Changes in v3:
- place braces according to the coding style
- add the changes made in v1 because v2 was incremental to v1

Rather than "proper tag", do you mean "commit-id"?

I think the former is a bit more clear what's the actual size, but the
end result is the same, I can change that.

I need to keep this structure somewhere DMA-reachable for the device (as
in - included in appropriate IOMMU context). Patch 8/10 is doing it. And
also, patch 8/10 is putting it together with other DMA-reachable
structures (not a separate page on its own). If I'd make it a separate
static variable (not part of that later struct), I'd need to reserve the
whole page for it - to guarantee no unrelated data lives on the same
(DMA-reachable) page.

As for statically initializing it, if would require the whole
(multi-page DMA-reachable) thing living in .data, not .bss, so a bigger
binary (not a huge concern due to compression, but still). But more
importantly, I don't know how to do it in a readable way, and you have
complained about readability of initializer of this structure in v2.

See above - it cannot share page with unrelated Xen data.

I can try, but I'm not exactly sure how to make readable UTF-16
literals...

... the array access will degenerate when i is "int", but will be okay
when i is "unsigned int" (and of course everything will break if
MAX_SERCONS > UINT_MAX).

unsigned int please, again (yet more further down).

This for() would better gain braces.

In order to use p here, I think we want (need?) to make
serial_parse_handle()'s parameter const char *.

Does this change belong elsewhere?

I have to admit that I'd see no issue if these lived side by side with
e.g. other string literals. The more that the device is supposed to be
exposed to Dom0 only anyway, and hence that'll be the only domain able
to get at that data.

L"Xen" looks sufficiently readable to me. We use this all over the
place in the EFI interfacing code.

exist at this point.

Actually: With your plan to expose the device to a DomU, how is that
going to work without tool stack adjustments? Wouldn't you need to
prevent in particular HVM/PVH guests from using the GFNs corresponding
to the MFNs where this Xen data is? The minimal requirement then would
seem to be an E820 reserved range for the area.

No. I was actually expecting the piece of data we're talking about here
to land in .rodata, and hence be re-usable at the same address for all
devices. Hence my reference to string literals.

I'm following here types used in the rest of IOMMU code. Especially,
this field is later passed to iommu_grdm_t func, which is:

typedef int iommu_grdm_t(xen_pfn_t start, xen_ulong_t nr, u32 id, void *ctx=
t);
                                                          ^^^^

I can probably use pci_sbdf_t here, but it will be cast to u32 later
anyway...

Ok.

"all devices" - this driver supports only a single xhci debug console at

live in .rodata), which given your earlier comments about memory usage
is probably worse.

Oh, sorry - I've got confused by your multiple consoles patch here.

In your earlier reply you did say you'd see no issue with this sitting
side by side with other string literals. Which is precisely how I
would envision to avoid the need to reserve the entire page. But yes,
if that's not feasible, then the current model of keeping the stuff
in .bss is likely best. A remark in the description towards the purpose
here and the further intentions might help, not the least to avoid me
coming up with the same comment again for a future version of the
series.

Subject: [RFC PATCH 4/4] x86: Use linkage.h helpers to add tags to symbols
Date: Thu, 4 Aug 2022 16:04:24 +0100
Message-ID: <20220804150424.17584-5-jane.malalane@citrix.com>
X-Mailer: git-send-email 2.11.0
In-Reply-To: <20220804150424.17584-1-jane.malalane@citrix.com>
References: <20220804150424.17584-1-jane.malalane@citrix.com>
MIME-Version: 1.0
Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: 8bit

Clean up x86_64/kexec_reloc.S and x86_64/entry.S.

This fixes the livepatching contents of entry.S.

RFC: I'm unsure on where the page_fault symbol should end, i.e. if
unlike current code handle_exception_saved should be within page_fault
like handle_exception is or not.

  xen: Port linkage.h from kernel code
  x86/entry: move .init.text section higher up in the code for
    readability
  x86: Use linkage.h helpers to add tags to symbols

  - On x86 "vga=current" can now be used together with GrUB2's gfxpayload setting. Note that
    this requires use of "multiboot2" (and "module2") as the GrUB commands loading Xen.
 
+### Added / support upgraded
+ - IOMMU superpage support on x86, affecting PV guests as well as HVM/PVH ones
+   when they don't share page tables with the CPU (HAP / EPT / NPT).
+
 ### Removed / support downgraded
  - dropped support for the (x86-only) "vesa-mtrr" and "vesa-remap" command line options

Sure. It is now committed.

I would suggest to mention in the commit message (or possibly use Fixes 
tags) that this was dropped in 8868a0e3f674 ("docs: update the xenstore 
migration stream documentation).

I am a bit concerned with the bump of the versions. It means, it will be 
necessary for Xenstored to know whether the new Xenstored speaks v1 or 
v2. This is less an issue when Live-Migration (although there is a fleet 
management problem) but it will be one for Live-Update if we need to 
rollback.

So I am wondering if we can avoid to bump the version and use other 
means to detect the difference.

I think we can avoid extending the structure here by creating a separate 
record for the quota.

With that, the new Xenstored don't need specific code to deal with 
rollback because, as AFAICT, unimplemented records are ignored by 
existing Xenstored.

 From my understanding, both version of Xenstored needs to agree on the 
quota names. So it means the name have to be defined as part of the 
spec. At which point, I think it would be better to use ID.

Also, can you clarify what would happen if the stream contains a quota 
not supported by the new Xenstored?

For the purpose of the stream, I would consider to make it available for 
the socket connection. This could potentially be used in the future to 
allow each application to have a different behavior when socket is used.

I can't make my mind yet if we can avoid bumping the version for this 
field. What would happen if we need to rollback?

I would suggest to be very obvious and say the value will override the 
value (if any)

As for the "global" quotas, I would move the quotas in a separate 
record. In this case, this would also be useful to avoid having may 
dynamic length field within the same record.

If we are going to bump the stream version, then I think we should move 
the field before token/path.

Doesn't unsigned int suffice as a return type here?

The function's return type is int64_t but the sole return statement
hands back an unsigned int - what's the deal here?

I've been trying to identify the reason for the alignment here,
compared to the other buffers which are no longer page-aligned. I
haven't even been able to locate the place where the address of
this buffer is actually written to hardware; all I could find was
the respective virt_to_maddr(). Could you please point me at that?

Actually I should have clarified yesterday that despite my effort to
review this change, I'm not convinced of its need. I simply don't see
the use case of having multiple serial consoles at a time, and afaict
console and gdb connection can already be run over different channels.

Which is one of the main reasons why I view DomU exposure as
going too far, despite recognizing the argument that this would only
be done if that DomU is fully trusted.

Furthermore - what's the effect of this? It would seem to me that
while bus mastering is off, the device will not function. What happens
to output occurring during that time window? Rather than needing to
re-enable bus mastering behind the owning domain's back, can't the
disabling of bus mastering be avoided in the driver there? As we can
see from the EHCI driver, there certainly can be communication
between Xen and Dom0 for functionality-impacting operations Dom0
might perform (there it's a device reset iirc).

I'm sorry, upon looking here more closely, can we use proper boolean
here as we do elsewhere, i.e. share=no|yes|hwdom (or more generically
expressed share=<boolean>|hwdom)?

I also think 'hwdom' should be the default, like we do for EHCI (with,
at present, not even a way to override).

As said above - this ought to be avoidable if the period of time the
reset takes is bounded and if the controlling domain announces the
reset and its completion. See ehci-dbgp.c:dbgp_op().

In any event I'd like to ask that you add a statement to the effect of
"no security support when using 'any'".

How can this allow use of the device by a domain? Is there some sort of
guarantee that nothing else will live in the same 4k range? I can't
infer such from xhci_find_dbc().

Looks like e (and hence opt) cannot be NULL here, ...

... nor here. Hence I wonder why the while() and ...

... this if() check for it being (non-)NULL. At which point ...

... you could make the message here more specific by passing "opt"
instead of the full "opt_dbgp".

Same as xhci_trb_norm_len()?

I can't seem to be able to spot any use of this function - it being
static, how do things build for you?

I think I've seen this constant in earlier patches. Can this be
a #define please, such that one can easily connect all the places
where the same things is meant?

What made me spot the lack of caller are these return statements.
Without letting the caller know of the failure, how would it know
to make another attempt later?

In MASK_DECLARE_1(), the macro parameter 'x' is used as expression and
therefore it is good to be enclosed in parentheses to prevent against
unintended expansions.

    Merge tag 'pull-ppc-20220804' of https://gitlab.com/danielhb/qemu into staging
    
    ppc patch queue for 2022-08-04:
    
    In this short queue we have a fix in the sam460ex machine where we're
    not storing all GPIO lines in sam460ex_init().
    
    This is not causing problems (as far as we're aware of) at this moment,
    but this is getting in the way of a ppc405 rework we want to do for 7.2,
    so let's fix it now.

    hw/ppc: sam460ex.c: store all GPIO lines in mal_irqs[]
    
    We're not storing all GPIO lines we're retrieving with
    qdev_get_gpio_in() in mal_irqs[]. We're storing just the last one in the
    first index:
    
        for (i = 0; i < ARRAY_SIZE(mal_irqs); i++) {
            mal_irqs[0] = qdev_get_gpio_in(uic[2], 3 + i);
        }
        ppc4xx_mal_init(env, 4, 16, mal_irqs);
    
    mal_irqs is used in ppc4xx_mal_init() to assign the IRQs to MAL:
    
        for (i = 0; i < 4; i++) {
            mal->irqs[i] = irqs[i];
        }
    
    Since only irqs[0] has been initialized, mal->irqs[1,2,3] are being
    zeroed.
    
    This doesn´t seem to trigger any apparent issues at this moment, but
    Cedric's QOMification of the MAL device [1] is executing a
    sysbus_connect_irq() that will fail if we do not store all GPIO lines
    properly.

If you adjust these, you also ...

.. want to adjust all of these, as they all have a similar issue.
And while doing such adjustments, please also add the missing blanks
around + .

However, these are macros used locally in a single .c file only, so
I'm not convinced as strict rules need to apply here. To make clear
no further uses (farther apart from the macro definitions) are
intended, an option would be to add #undef-s right after
cpu_bit_bitmap[]'s initializer. (But this is not an objection to
adding the parentheses, just a general remark.)

In the title you say "port", but then you don't say what customization
you've done beyond the obvious adjustment of inclusion guard and
adjustment (actually removal) of #include-s. How much customization we
want to do is important here, after all. I notice you did, for example,
add new flavors of SYM_INNER_LABEL, but then you didn't add anything to
use .hidden (which I have queued as a new patch on top of a supposed v2
of "x86: annotate entry points with type and size"). At the same time
you've left in objtool related commentary, when we don't use that tool
(and no-one knows if we ever will).

I'm further not sure I agree with the naming of some of your additions,
as they appear to not really fit with the naming model used elsewhere.
Your additions also look to not always match style used elsewhere in
this file.

You further want to mention what Linux version this was derived from,
to make it easier to determine what incremental changes to port over
subsequently.

Overall I'm not convinced this is a model we want to go with, first
and foremost because the commonly used macro names are too long for
my taste. What's wrong with ENTRY() and ENDPROC() / ENDDATA()?

I.e. the opposite of what the patch currently does. That's fine with me
in principle (sadly there's no STT_THUNK or alike, which might allow
better reflecting the purpose yet still not marking these as STT_FUNC
nor leaving them at STT_NOTYPE), but the small stubs then want an end
annotation, so that their code is covered by some [start,start+size)
pair in the symbol table. IOW I think that as a final result (not
necessarily right after this series) we want all code and data
contributions to be covered by such a range. Which in turn means for
this series that _if_ an area is touched, it should be brought into
that intended shape.

And also, the only use for the return value is comparing to 0. So, yes,
should be unsigned int.

Yes, I was considering to use that, but technically those are different

It's in dbc_uart_poll().

Similar reason as previously - to guarantee it isn't put with unrelated

directly. But, since this patch doesn't attempt to handle IOMMU
situation yet, I think I can drop it here too as there is little benefit
for trying here.

That's rebase fail, it should be changed to 16 initial patch too.

Subject: [PATCH] x86/spec-ctrl: Use IST RSB protection for !SVM systems
Date: Fri, 5 Aug 2022 11:38:14 +0100
Message-ID: <20220805103814.23032-1-andrew.cooper3@citrix.com>
X-Mailer: git-send-email 2.11.0
MIME-Version: 1.0

There is a corner case where a VT-x guest which manages to reliably trigger
non-fatal #MC's could evade the rogue RSB speculation protections that were
supposed to be in place.

This is a lack of defence in depth; Xen does not architecturally execute more
RET than CALL instructions, so an attacker would have to locate a different
gadget (e.g. SpectreRSB) first to execute a transient path of excess RET
instructions.

Subject: [PATCH] xen/wait: Describe RSB safety
Date: Fri, 5 Aug 2022 11:38:40 +0100

It turns out that we do in fact have RSB safety here, but not for obvious
reasons.

Thanks for letting me know. I've started to work in it.

I've also found out that "-sdl" is going away.

needed :-). (At least, I hope using -device instead -soundhw is going to
work the same way.)

In MASK_DECLARE_ macros, the macro parameter 'x' is used as expression and
therefore it is good to be enclosed in parentheses to prevent against
unintended expansions.

Changes in v2:
- fix MISRA C 2012 Rule 20.7 violation in all MASK_DECLARE_ macros

That's kind of the purpose of those helper functions - to extract

However,
- I don't see why patches 1 and 2 needed splitting, when patch 1 already
  touches all those lines. It is the usual thing for us to make cosmetic
  adjustments when touching a line anyway.
- Patch 3, while fine to be separate, wants a Requested-by: or
  Suggested-by: me (which I guess can be taken care of while committing).

In my opinion, the initial patch that added the code should not have 
been accepted in first place without the white spaces around '+'.
But maybe coding style rules came later.
Nevertheless, I continue to consider it unfair to rely on and request 
from new unrelated patches to fix those issues.

I agree the usefulness is limited. I needed this only to debug the xhci
console driver itself. But since I did this change already, I figured
I'd share it as it might be useful for others in similar situation.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

  commit 66dd1c62b2a3c707bd5c55750d10a8223fbd577f
  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

I can certainly see where you're coming from, but please also try to take
maintainer perspective: By doing trivial and obvious adjustments at the
same time when touching code anyway, there's one less patch to look at
(and later to apply). And please also consider how "git blame" or alike
works: By touching the same line(s) twice in close succession, finding
the "real" change is made needlessly harder. (Putting the cosmetic change
first is generally disliked because it makes backporting harder, in case
such is wanted / needed.)

I'm sorry if you take such requests as unfair - they aren't meant to be.
They're merely meant to make things as easy as possible for everyone
(which may only be on average, yes).

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend

  commit 66dd1c62b2a3c707bd5c55750d10a8223fbd577f
  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

Subject: [PATCH] [RFC] xen/vpci: modify pci_get_pdev_by_domain() & pci_get_pdev()
Date: Fri,  5 Aug 2022 16:43:43 +0100
Message-Id: <5650ddce1de4fd5471823bde44a12a03f157bc11.1659713913.git.rahul.singh@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

pci_get_pdev_by_domain() and pci_get_pdev() functions find the pdev in
the pseg list. If pdev is not in the pseg list, the functions will try
to find the pdev in the next segment. It is not right to find the pdev
in the next segment as this will result in the corruption of another
device in a different segment with the same BDF.

An issue that was observed when implementing the PCI passthrough on ARM.
When we deassign the device from domU guest, the device is assigned
to dom_io and not to dom0, but the tool stack that runs in dom0 will try
to configure the device from dom0. vpci will find the device based on
conversion of GPA to SBDF and will try to find the device in dom0, but
because device is assigned to dom_io, pci_get_pdev_by_domain() will
return pdev with same BDF from next segment.

When devices are deassigned/assigned, SMMU global fault is observed
because SMEs are freed in detach function and not allocated again when
the device is assigned back to the guest.

Don't free the SMEs when devices are deassigned, set the s2cr to type
fault. This way the SMMU will generate a fault if a DMA access is done
by a device not assigned to a guest

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

is_memory_hole was implemented for x86 and not for ARM when introduced.
Replace is_memory_hole call to pci_check_bar as function should check
if device BAR is in defined memory range. Also, add an implementation
for ARM which is required for PCI passthrough.

On x86, pci_check_bar will call is_memory_hole which will check if BAR
is not overlapping with any memory region defined in the memory map.

On ARM, pci_check_bar will go through the host bridge ranges and check
if the BAR is in the range of defined ranges.

If no reset happens, the controller will continue sending the data after
bus mastering is enabled back - no data lost in this case. If reset does
happen, data that was already handed off to the controller (TRB queued)
but not sent yet, is lost. But data that is still queued only in the
work_ring, will be sent after controller is re-initialized. I did
several tests of this, and I have not noticed any data loss in practice.

Linux disables bus mastering when PCI devices are enumerated (before
xhci driver is loaded at all), and enables it back only when xhci driver
tells it so. So, if xhci driver in dom0 is blacklisted (which is the
case in qubes by default...), the console would be much less useful, so
to say. And I don't think Linux maintainers will appreciate xen-xhci-dbc
specific code in core PCI handling...
It isn't an issue for EHCI driver, because EHCI debug port
interface does not seem to use DMA.

Yes, I can see how controller reset can be coordinated this way. But
also, I see it more like a future improvement if it deemed to be
necessary, than a strict requirement, as the controller reset is a quick
event that in practice does not impact the functionality in any
significant way (with the current code shape). On the other hand, adding
such synchronization feels like several more iterations of this
series...

And BTW, if Linux crashes in the middle of controller reset, with such
synchronization you would not get the crash message at all. While
admittedly such issue is rather unlikely, I see it as a potential
downside of coordination here (you could still avoid it by
`share=3Dnone`/`share=3Dno`, with all its consequences).

Generally, what would be your minimal acceptable version? If support for
sharing the controller with a domain (including dom0) requires
significantly more work to be accepted, I'd much prefer to drop it in
this series and have it possibly introduced later (and in the meantime,
possibly carry as a downstream patch). Unfortunately, I have limited
time to work on the series, but also, I think having this feature
upstream - even in partial form - will be very useful for many Xen users
and developers. Especially, I'd like this series (in some shape) to be
included in Xen 4.17.

Sure, I can add it more even explicitly (there is already "it is not

That's a very good question. From what I see, it lives on a page
together with other extended capabilities (but nothing else). Most of
registers in other capabilities are read-only, but there are some
read-write. It seems Linux driver works fine without writing to any of
them, but it sounds very fragile...

The main reason for this code is to prevent Linux initializing DbC for
itself. But AFAIK Linux does not do it on its own, it requires explicit
action from the system admin (a write to sysfs or kernel option).
I'm not exactly sure what will happen if Linux will try to use DbC too,
my guess is either Xen console will stall, or they will fight each other
by re-initializing DbC over and over. Neither of them look appealing...

Would you prefer to drop this part, in favor of documenting it's the
system admin responsibility to prevent Linux from using it? In that
case, I think the default should remain `share=3Dno` (possibly changing
only after implementing some coordination with Linux side).

Yes, indeed.

Thanks for the ping.  Since 71020a3c0dff4 is by Thomas, and he merged
that along with a whole series of MSI work, I think I probably
expected him to take care of this.

This looks like a simple typo, so I think the commit log should be
reworded along that line, e.g., something like:

  71020a3c0dff4 ("PCI/MSI: Use msi_add_msi_desc()") inadvertently
  reversed the sense of "msi_attrib.can_mask" in one use:

    - if (entry->pci.msi_attrib.can_mask) {
    -         addr = pci_msix_desc_addr(entry);
    -         entry->pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);
    + if (!desc.pci.msi_attrib.can_mask) {
    +         addr = pci_msix_desc_addr(&desc);
    +         desc.pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);

  Restore the original test.

Thomas, do you want to take this?  I'm happy to merge it, but would
like your reviewed-by or ack first.

Bjorn

    ppc patch queue for 2022-08-04:
    
    In this short queue we have a fix in the sam460ex machine where we're
    not storing all GPIO lines in sam460ex_init().
    
    This is not causing problems (as far as we're aware of) at this moment,
    but this is getting in the way of a ppc405 rework we want to do for 7.2,
    so let's fix it now.

    hw/ppc: sam460ex.c: store all GPIO lines in mal_irqs[]
    
    We're not storing all GPIO lines we're retrieving with
    qdev_get_gpio_in() in mal_irqs[]. We're storing just the last one in the
    first index:
    
        for (i = 0; i < ARRAY_SIZE(mal_irqs); i++) {
            mal_irqs[0] = qdev_get_gpio_in(uic[2], 3 + i);
        }
        ppc4xx_mal_init(env, 4, 16, mal_irqs);
    
    mal_irqs is used in ppc4xx_mal_init() to assign the IRQs to MAL:
    
        for (i = 0; i < 4; i++) {
            mal->irqs[i] = irqs[i];
        }
    
    Since only irqs[0] has been initialized, mal->irqs[1,2,3] are being
    zeroed.
    
    This doesn´t seem to trigger any apparent issues at this moment, but
    Cedric's QOMification of the MAL device [1] is executing a
    sysbus_connect_irq() that will fail if we do not store all GPIO lines
    properly.

    include/qemu/host-utils.h: Simplify the compiler check in mulu128()
    
    We currently require at least GCC 7.4 or Clang 6.0 for compiling QEMU.
    GCC has __builtin_mul_overflow since version 5 already, and Clang 6.0
    also provides this built-in function (see its documentation on this page:
    https://releases.llvm.org/6.0.0/tools/clang/docs/LanguageExtensions.html ).
    So we can simplify the #if statement here.

I saw Jan commenting on this. I agree with him to switch to

if ( d )
{
   ASSERT_UNREACHABLE();
   return;
}

I would even go further and add a printk() to log the problem in prod.

NIT: The removal of #ifdef seems to be unrelated to this patch. If you 
plan to send a v10, then I would suggest to mention it on the commit 
message.

I saw Jan commenting on this change. So, FYI, I am OK either way.

Hi Penny,

Sorry I only spotted a couple of typos in the commit message now.

On 20/07/2022 06:46, Penny Zheng wrote:

s/accidently/accidentally/ I think.

s/PGC_reserved/PGC_staticmem/

I think both #1 and #3 can go in now. So I would be happy to handle the 
typoes on commit.

Subject: [PATCH 2/2] automation: qemu-smoke-arm64: Run ping test over a pv network interface
Date: Sat,  6 Aug 2022 00:17:41 +0300
Message-Id: <20220805211741.1869068-3-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
In-Reply-To: <20220805211741.1869068-1-burzalodowa@gmail.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch modified the test in the following way
- Dom0 is booted with an alpine linux rootfs with the xen tools.
- Once Dom0 is booted, it starts xenstored, calls init-dom0less to setup
the xenstore interface for the dom0less Dom1, setups the bridged network
and attaches a pv network interface to Dom1.
- In the meantime, Dom1 in its init script tries to assign an ip to eth0
and ping Dom0,
- If Dom1 manages to ping Dom0, it prints 'passed'.

Use kernel 5.19 to unblock testing dom0less enhanced.
This kernel version has the necessary patches for deferring xenbus probe
until xenstore is fully initialized.
Also, build kernel with bridging and xen netback support enabled because
it will be used for testing network connectivity between Dom0 and Dom1
over a pv network interface.

If you are OK with it, I can remove "3.12" on commit.

    ppc patch queue for 2022-08-04:
    
    In this short queue we have a fix in the sam460ex machine where we're
    not storing all GPIO lines in sam460ex_init().
    
    This is not causing problems (as far as we're aware of) at this moment,
    but this is getting in the way of a ppc405 rework we want to do for 7.2,
    so let's fix it now.

    hw/ppc: sam460ex.c: store all GPIO lines in mal_irqs[]
    
    We're not storing all GPIO lines we're retrieving with
    qdev_get_gpio_in() in mal_irqs[]. We're storing just the last one in the
    first index:
    
        for (i = 0; i < ARRAY_SIZE(mal_irqs); i++) {
            mal_irqs[0] = qdev_get_gpio_in(uic[2], 3 + i);
        }
        ppc4xx_mal_init(env, 4, 16, mal_irqs);
    
    mal_irqs is used in ppc4xx_mal_init() to assign the IRQs to MAL:
    
        for (i = 0; i < 4; i++) {
            mal->irqs[i] = irqs[i];
        }
    
    Since only irqs[0] has been initialized, mal->irqs[1,2,3] are being
    zeroed.
    
    This doesn´t seem to trigger any apparent issues at this moment, but
    Cedric's QOMification of the MAL device [1] is executing a
    sysbus_connect_irq() that will fail if we do not store all GPIO lines
    properly.

    include/qemu/host-utils.h: Simplify the compiler check in mulu128()
    
    We currently require at least GCC 7.4 or Clang 6.0 for compiling QEMU.
    GCC has __builtin_mul_overflow since version 5 already, and Clang 6.0
    also provides this built-in function (see its documentation on this page:
    https://releases.llvm.org/6.0.0/tools/clang/docs/LanguageExtensions.html ).
    So we can simplify the #if statement here.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

    Currently there is no labels for start and end of the

    Currently there is no labels for start and end of the

    Add labels for start and end of the FV sections to fix the issue.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

Subject: getting gitlab pipeline status

Hi,

Related to an IRC chat few days ago - here is how to get gitlab pipeline st=
atus:

# get latest pipeline of a branch
$ curl -s 'https://gitlab.com/api/v4/projects/xen-project%2Fxen/pipelines?r=
ef=3Dstaging' | jq -r '.[0].status'
success
# get latest pipeline of a commit (example of success and failure)
$ curl -s 'https://gitlab.com/api/v4/projects/xen-project%2Fxen/pipelines?s=
ha=3D6d6aee437e37fced0c49be97e08c30da873690fc' | jq -r '.[0].status'
success
$ curl -s 'https://gitlab.com/api/v4/projects/xen-project%2Fxen/pipelines?s=
ha=3Dda74c951e4e58080583daaad373b0d38a3f8bc83' | jq -r '.[0].status'
failed

Documentation:
https://docs.gitlab.com/ee/api/pipelines.html#list-project-pipelines

If making osstest push gate checking gitlab pipeline status is desirable
(IMO that would be helpful), the above should be enough. I'm not fluent
in osstest internals, but I hope it isn't too complex to add such
check...

    BaseTools/VolInfo: Show FV section boundaries
    
    Currently there is no labels for start and end of the
    EFI_SECTION_FIRMWARE_VOLUME_IMAGE type section. Therefore it is not
    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

    BaseTools/VolInfo: Show FV section boundaries
    
    Currently there is no labels for start and end of the
    EFI_SECTION_FIRMWARE_VOLUME_IMAGE type section. Therefore it is not
    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

    Currently there is no labels for start and end of the

    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

    Currently there is no labels for start and end of the

    Currently there is no labels for start and end of the

    Add labels for start and end of the FV sections to fix the issue.

    BaseTools/VolInfo: Show FV section boundaries
    
    Currently there is no labels for start and end of the
    EFI_SECTION_FIRMWARE_VOLUME_IMAGE type section. Therefore it is not
    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

    BaseTools/VolInfo: Show FV section boundaries
    
    Currently there is no labels for start and end of the

    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

    Currently there is no labels for start and end of the

    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

    BaseTools/VolInfo: Parse EFI_SECTION_FREEFORM_SUBTYPE_GUID header
    
    Print 'SubtypeGuid' field from the EFI_FREEFORM_SUBTYPE_GUID_SECTION
    structure.
    This value describes the raw data inside the section.

    BaseTools/VolInfo: Show FV section boundaries
    
    Currently there is no labels for start and end of the
    EFI_SECTION_FIRMWARE_VOLUME_IMAGE type section. Therefore it is not
    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

In macro psr_mode(), the macro parameter 'm' is used as expression and
therefore it is good to be enclosed in parentheses to prevent against
unintended expansions.

I think this is fine. Someone that cares about rollback will also likely 
care about fleet diversity. So they will want to avoid enabling a 
feature until they know it can work everywhere.

I don't have a strong opinion on this yet. I might have some when seen 
the code :).

I was actually thinking about this when writing the e-mail last week. 
There are no dynamic length array in the global records so far, so using 
the length information would be ok. I am more concerned about the others 
because we are mixing fixed and dynamic length.

This means it is more difficult to read the code and the layout.

Someone reading the migration stream will not necessarily read the 
Xenstore protocol. So I think we should either make them explicit in the 
documentation or have a link to the other document.

Fair enough.

I can't find such statement in public documentation. Do you have a link?

That said, a guest doesn't have a (easy?) way to know how Xenstored is 
implemented. So it is quite concerning to hear some of them may rely on 
behaviors. How did that happen?

I am not sure why it would break the use of xenstore-stubdom. An 
application will already need to cope with the case Xenstored doesn't 
support a feature.

At which point, it would be easy to say "I don't want this feature" when 
using a socket.

Which is fine so long the code doesn't become too horrible to 
read/maintain. I think having dynamic length array in the middle of the 
record makes it trickier.

This will only become worse as we introduce new fields in newer 
revision. So at which point would you say the record has grown too much?

To me, this is already the point and we have plenty of record ID to 
handle that.

The cons is you can't easily describe the record in "struct ...". As I 
wrote above, I think have dynamic length array in the middle of a record 
is wrong.

I have looked at the code, I don't think there will be enough code 
duplication to warrant adding fixed field at the end of the record.

"-sdl" is deprecated upstream since 6695e4c0fd9e ("softmmu/vl:
Deprecate the -sdl and -curses option"), QEMU v6.2, and the option is
removed by 707d93d4abc6 ("ui: Remove deprecated options "-sdl" and
"-curses""), in upcoming QEMU v7.1.

Instead, use "-display sdl", available since 1472a95bab1e ("Introduce
-display argument"), before QEMU v1.0.

Patch series available in this git branch:
https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.qemu-deprecated-soundhw-v1

Hi,

There's some more QEMU options that are deprecated. We still don't need to
figure out which QEMU version we are going to run as the options that replace
them already existed in QEMU 1.0, so all the version QEMU upstream that we
could possible use as device model.

Thanks,

Anthony PERARD (2):

Subject: [XEN PATCH 2/2] tools/libxl: Replace deprecated -soundhw on QEMU command line
Date: Mon, 8 Aug 2022 12:05:45 +0100
Message-ID: <20220808110545.62886-3-anthony.perard@citrix.com>

-soundhw is deprecated since 825ff02911c9 ("audio: add soundhw
deprecation notice"), QEMU v5.1, and is been remove for upcoming v7.1
by 039a68373c45 ("introduce -audio as a replacement for -soundhw").

Instead we can just add the sound card with "-device", for most option
that "-soundhw" could handle. "-device" is an option that existed
before QEMU 1.0, and could already be used to add audio hardware.

The list of possible option for libxl's "soundhw" is taken the list
from QEMU 7.0.

The list of options for "soundhw" are listed in order of preference in
the manual. The first three (hda, ac97, es1370) are PCI devices and
easy to test on Linux, and the last four are ISA devices which doesn't
seems to work out of the box on linux.

The sound card 'pcspk' isn't listed even if it used to be accepted by
'-soundhw' because QEMU crash when trying to add it to a Xen domain.
Also, it wouldn't work with "-device" might need to be "-machine
pcspk-audiodev=default" instead.

    BaseTools/VolInfo: Show FV section boundaries
    
    Currently there is no labels for start and end of the
    EFI_SECTION_FIRMWARE_VOLUME_IMAGE type section. Therefore it is not
    possible to see where the FV section ends and another section starts.
    Add labels for start and end of the FV sections to fix the issue.

Hello Rahul

> From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

I am not 100% sure regarding that. This is *completely* different patch 
from what Oleksandr initially made here:

https://lore.kernel.org/xen-devel/20220719174253.541965-2-olekstysh@gmail.com/

Copy below for the convenience:


+bool is_memory_hole(mfn_t start, mfn_t end)
+{
+    /* TODO: this needs to be properly implemented. */
+    return true;
+}




Patch looks good, just a couple of minor comments/nits.

Nit: This is only used by pci-host-common.c, so I think it could be 
declared there.

The cast is present here because of the const?

I would consider passing "const struct pci_dev *pdev" instead of "struct 
device *dev" to pci_find_host_bridge_node() and dropping conversion 
(pci<->dev) in both functions.

Nit: I would use simple #define instead of static inline here

But I am not 100% sure that x86 maintainers would be happy.

Well, I don't think it matters which is used between $(RM) and rm -f,

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-amd64-libvirt           6 libvirt-build            fail REGR. vs. 172136

    I think that "virtio_enabled = true;" should be moved ...

  ... here. Otherwise after applying all patches "virtio_enabled" only 
gets set if there is a virtio disk device. So it won't be set for virtio 
i2c, etc.

I see that in V2 it was there, but in V3 is not. Or maybe there is some 
reason for doing that which I am not aware of?


Other changes look good.

Use kernel 5.19 to unblock testing dom0less enhanced.
This kernel version has the necessary patches for deferring xenbus probe
until xenstore is fully initialized.
Also, build kernel with bridging and xen netback support enabled because
it will be used for testing network connectivity between Dom0 and Dom1
over a pv network interface.

Subject: [PATCH v2 2/2] automation: qemu-smoke-arm64: Run ping test over a pv network interface
Date: Mon,  8 Aug 2022 21:39:52 +0300
Message-Id: <20220808183952.1888459-3-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
In-Reply-To: <20220808183952.1888459-1-burzalodowa@gmail.com>

This patch modified the test in the following way
- Dom0 is booted with an alpine linux rootfs with the xen tools.
- Once Dom0 is booted, it starts xenstored, calls init-dom0less to setup
the xenstore interface for the dom0less Dom1, setups the bridged network
and attaches a pv network interface to Dom1.
- In the meantime, Dom1 in its init script tries to assign an ip to eth0
and ping Dom0,
- If Dom1 manages to ping Dom0, it prints 'passed'.

Changes in v2:
- rebase against the latest changes on staging
- search for 'Welcome to Alpine Linux' instead of 'Welcome to Alpine Linux 3.12'
so that the test is not bound to a specific Alpine Linux version
- do not disable dom0less enhanced in the ImageBuilder script

[I failed to find a better place where to make a comment]


I think that the following chunk should be also moved to 
make_virtio_mmio_node_common() since it is not a virtio disk specific 
action, this "iommus" property pointing to "xen,grant-dma" IOMMU node is 
used to inform a guest that restricted memory access using Xen grant 
mappings needs to be enabled for the virtio device if it's backend is 
going to run in a non hardware domain, which I assume also applies for 
virtio i2c, etc.


     if (backend_domid != LIBXL_TOOLSTACK_DOMID) {
         uint32_t iommus_prop[2];

         iommus_prop[0] = cpu_to_fdt32(GUEST_PHANDLE_IOMMU);
         iommus_prop[1] = cpu_to_fdt32(backend_domid);

         res = fdt_property(fdt, "iommus", iommus_prop, 
sizeof(iommus_prop));
         if (res) return res;
     }


This means that "uint32_t backend_domid" should be also passed as 
argument to make_virtio_mmio_node_common()


Something like the diff on top of current patch below (not tested):

Other changes look good.

I think that patch needs to be updated according to the suggestion 
provided for "[PATCH V3 4/6] libxl: arm: Split make_virtio_mmio_node()" 
(of course, if you agree with it).

If so, the make_virtio_mmio_node_i2c() should gain "uint32_t 
backend_domid" argument, etc. And with introducing new virtio i2c the 
make_xen_iommu_node() should also be called for it if not created yet 
(or maybe better to have only single invocation of make_xen_iommu_node() 
at the end)


Something like the diff on top of current patch below (not tested):

I think that patch needs to be updated taking into the account 
suggestions provided for two previous patches (of course, if you agree 
with them).

If so, the make_virtio_mmio_node_gpio() should gain "uint32_t 
backend_domid" argument, etc. And we need to make sure that 
make_xen_iommu_node() will be called for virtio gpio.

commit 1da2012d938f141821740324e2dceee1b4cfa76d
Author: Jose Marinho <jose.marinho@arm.com>
Date:   Tue Jul 26 17:54:42 2022 +0100

    PrmPkg: Add details on AArch64 build to the Readme.
    
    Specify how to build the PrmPkg for the AArch64 architecture.
    Make the 2 following notes:
     - the PrmPkg has only been tested on AArch64 using the GCC5
    toolchain.
     - All symbols to be listed in the PRMT as well as the
    PrmModuleExportDescriptor must be explicitly preserved by resorting to
    the --require-defined linker flag.

    PrmPkg: Build Prm Samples with GCC for AARCH64
    
    - Add the --prm flag to the GENFW_FLAGS
    - Add the --no-gc-section to the linker flags so that apparently
    unreferenced symbols are not prematurely removed from the .dll which
    is used to generate the Prm module .efi.
    - Force the linker to maintain the PrmModuleExportDescriptor symbol.
    - Force the linker to maintain the PRM handler funtion's symbol.

Author: Jose Marinho <jose.marinho@arm.com>
Date:   Fri Oct 29 17:48:26 2021 +0100

    Basetools/GenFw: Allow AARCH64 builds to use the --prm flag
    
    The GenFw invocation with the --prm flag was previously reserved for
    X64.
    AArch64 platforms, built with GCC5, can also deploy PRM modules, hence
    the --prm flag is also applicable in builds targeting the AARCH64
    architecture.
    
    This commit enables the --prm flag to be used for EDK2 builds targeting
    AARCH64.

    PrmPkg: Add details on AArch64 build to the Readme.
    
    Specify how to build the PrmPkg for the AArch64 architecture.
    Make the 2 following notes:
     - the PrmPkg has only been tested on AArch64 using the GCC5
    toolchain.
     - All symbols to be listed in the PRMT as well as the
    PrmModuleExportDescriptor must be explicitly preserved by resorting to
    the --require-defined linker flag.

    - Add the --prm flag to the GENFW_FLAGS
    - Add the --no-gc-section to the linker flags so that apparently

    is used to generate the Prm module .efi.
    - Force the linker to maintain the PrmModuleExportDescriptor symbol.
    - Force the linker to maintain the PRM handler funtion's symbol.

    Basetools/GenFw: Allow AARCH64 builds to use the --prm flag
    
    The GenFw invocation with the --prm flag was previously reserved for
    X64.
    AArch64 platforms, built with GCC5, can also deploy PRM modules, hence
    the --prm flag is also applicable in builds targeting the AARCH64
    architecture.
    
    This commit enables the --prm flag to be used for EDK2 builds targeting
    AARCH64.

    Fix using RmrNodeCount uninitliased by initliasing it to zero. Also, add
    an additional check for ACPI version. This fixes a crash running on
    kvmtool.

Create a separate routine to allocate base and irq for a device as the
same code will be required for each device type.

Subject: [PATCH V4 0/6] Virtio toolstack support for I2C and GPIO on Arm
Date: Tue,  9 Aug 2022 11:04:27 +0530
Message-Id: <cover.1660023094.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514

Hello,

This patchset adds toolstack support for I2C and GPIO virtio devices. This is
inspired from the work done by Oleksandr for the Disk device.

This is developed as part of Linaro's Project Stratos, where we are working
towards Hypervisor agnostic Rust based backend [1].

This is based of origin/staging (commit 01ca29f0b17a ("sched: dom0_vcpus_pin
should only affect dom0")) which already has Oleksandr's patches applied.

V3->V4:
- Update virtio_enabled independently of all devices, so we don't miss setting
  it to true.

- Add iommu handling for i2c/gpio and move it as part of
  make_virtio_mmio_node_common(), which gets backend_domid parameter as a
  result.

V2->V3:
- Rebased over latest tree and made changes according to changes in Oleksandr's
  patches from sometime back.
- Minor cleanups.

V1->V2:
- Patches 3/6 and 4/6 are new.
- Patches 5/6 and 6/6 updated based on the above two patches.
- Added link to the bindings for I2C and GPIO.
- Rebased over latest master branch.


Thanks.

Subject: [PATCH V4 1/6] libxl: Add support for Virtio I2C device
Date: Tue,  9 Aug 2022 11:04:28 +0530
Message-Id: <6cd6ca9d72d4f844e8a007b687e28f49301fae03.1660023094.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
In-Reply-To: <cover.1660023094.git.viresh.kumar@linaro.org>
References: <cover.1660023094.git.viresh.kumar@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-i2c backend (emualator) which is intended to run out of
Qemu and could be run in any domain.

An example of domain configuration for Virtio I2c:
i2c = [ "" ]

Please note, this patch is not enough for virtio-i2c to work on Xen
(Arm), as for every Virtio device we need to allocate Virtio MMIO params
(IRQ and memory region) and pass them to the backend, also update Guest
device-tree. A subsequent patch will add these missing bits. For the
current patch, the default "irq" and "base" are just written to the
Xenstore.

Subject: [PATCH V4 2/6] libxl: Add support for Virtio GPIO device
Date: Tue,  9 Aug 2022 11:04:29 +0530
Message-Id: <ef815025eda7018cd713f13eb0d6a540e9deae9f.1660023094.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
In-Reply-To: <cover.1660023094.git.viresh.kumar@linaro.org>
References: <cover.1660023094.git.viresh.kumar@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-gpio backend (emualator) which is intended to run out of
Qemu and could be run in any domain.

An example of domain configuration for Virtio Gpio:
gpio = [ "" ]

Please note, this patch is not enough for virtio-gpio to work on Xen
(Arm), as for every Virtio device we need to allocate Virtio MMIO params
(IRQ and memory region) and pass them to the backend, also update Guest
device-tree. A subsequent patch will add these missing bits. For the
current patch, the default "irq" and "base" are just written to the
Xenstore.

Message-Id: <25fa5be0459f2f790f8420540840ea951a2f872e.1660023094.git.viresh.kumar@linaro.org>

make_virtio_mmio_node() creates the DT node for simple MMIO devices
currently, i.e. the ones that don't require any additional properties.

In order to allow using it for other complex device types, split the
functionality into two, one where the fdt node isn't closed and the
other one to create a simple DT node.

    PrmPkg: Add details on AArch64 build to the Readme.
    
    Specify how to build the PrmPkg for the AArch64 architecture.
    Make the 2 following notes:
     - the PrmPkg has only been tested on AArch64 using the GCC5
    toolchain.
     - All symbols to be listed in the PRMT as well as the
    PrmModuleExportDescriptor must be explicitly preserved by resorting to
    the --require-defined linker flag.

    - Add the --prm flag to the GENFW_FLAGS
    - Add the --no-gc-section to the linker flags so that apparently

    is used to generate the Prm module .efi.
    - Force the linker to maintain the PrmModuleExportDescriptor symbol.
    - Force the linker to maintain the PRM handler funtion's symbol.

    Basetools/GenFw: Allow AARCH64 builds to use the --prm flag
    
    The GenFw invocation with the --prm flag was previously reserved for
    X64.
    AArch64 platforms, built with GCC5, can also deploy PRM modules, hence
    the --prm flag is also applicable in builds targeting the AARCH64
    architecture.
    
    This commit enables the --prm flag to be used for EDK2 builds targeting
    AARCH64.

But the struct isn't cpupool specific, and hence controlling the setting up
of the field via a function parameter doesn't really look like a layering
violation to me. While imo the end result would be more clean (as in - all
allocations / freeing in one place), I'm not going to insist (not the least
because I'm not maintainer of that code anyway).

I think I could agree with such logic as a temporary measure, i.e. marked
clearly with a FIXME: or alike. The Kconfig option then also would want
marking "experimental" (or maybe it already is).

No, quite the other way around - it being there makes Xen's use safe,

Perhaps - if what the function does really resembles allocation in some
way. So far I wasn't really certain in that regard, and hence I was
wondering whether "prepare" doesn't better describe what it does, but
then its inverse also doesn't really "free" anything.

    UefiCpuPkg: Simplify the struct definition of CPU_EXCEPTION_INIT_DATA
    
    CPU_EXCEPTION_INIT_DATA is now an internal implementation of
    CpuExceptionHandlerLib. Union can be removed since Ia32 and X64 have the
    same definition. Also, two fields (Revision and InitDefaultHandlers)are
    useless, can be removed.

    Specify how to build the PrmPkg for the AArch64 architecture.
    Make the 2 following notes:
     - the PrmPkg has only been tested on AArch64 using the GCC5
    toolchain.
     - All symbols to be listed in the PRMT as well as the
    PrmModuleExportDescriptor must be explicitly preserved by resorting to
    the --require-defined linker flag.

    PrmPkg: Build Prm Samples with GCC for AARCH64
    
    - Add the --prm flag to the GENFW_FLAGS
    - Add the --no-gc-section to the linker flags so that apparently
    unreferenced symbols are not prematurely removed from the .dll which
    is used to generate the Prm module .efi.
    - Force the linker to maintain the PrmModuleExportDescriptor symbol.
    - Force the linker to maintain the PRM handler funtion's symbol.

    Basetools/GenFw: Allow AARCH64 builds to use the --prm flag
    
    The GenFw invocation with the --prm flag was previously reserved for
    X64.
    AArch64 platforms, built with GCC5, can also deploy PRM modules, hence
    the --prm flag is also applicable in builds targeting the AARCH64
    architecture.
    
    This commit enables the --prm flag to be used for EDK2 builds targeting
    AARCH64.

To be honest I was hoping you would make an attempt at finding a suitable
pair of verbs. To me "destroy" is more the opposite of "create", and I'm
unable to think of a good opposite of "prepare" (short of resorting to
"unprepare"); if I really needed to come up with something then it would
likely be "cleanup", albeit I'd not be overly happy with that either.

Subject: [PATCH] xen/arm: vreg: Fix MISRA C 2012 Rule 20.7 violation
Date: Tue,  9 Aug 2022 12:30:48 +0300
Message-Id: <20220809093048.1893025-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

In VREG_REG_HELPERS(), the macro parameter 'offmask' is used as expression and
therefore it is good to be enclosed in parentheses to prevent against
unintended expansions.

Indeed present behavior is wrong - thanks for spotting. However in
both cases you're moving us from one wrongness to another: The
lookup of further segments _is_ necessary when the incoming "seg"
is -1 (and apparently when this logic was introduced that was the
only case considered).

As an aside - my mail UI shows me unexpected threading between
this patch and two subsequent ones. If they were actually meant
to be a series, can they please be marked n/3?

Nit: No new uses of u64 please use uint64_t instead.

Quite the other way around - when possible we prefer inline functions.
And note that the two functions are strictly aliases of one another
(in which case a simplified

#define pci_check_bar is_memory_hole

might indeed have been worth a consideration, as there's no type
safety to be lost in such cases).

Is it worth mentioning driver support?  I think Windows 7 and later
only have a built-in driver for hda.  Windows 7 definitely doesn't
have a built-in driver for ac97.  I think all the other devices are
even older, so I doubt Windows has drivers for those, but I have not
checked.

Subject: [PATCH v12] xsm: refactor flask sid alloc and domain check
Date: Tue,  9 Aug 2022 10:06:33 -0400

The function flask_domain_alloc_security() allocates the security context and
assigns an initial SID for the domain under construction. When it came to SID
assignment of the initial domain, flask_domain_alloc_security() would assign
unlabeled_t. Then in flask_domain_create() it would be switched to dom0_t.
This logic worked under the assumption that the first domain constructed would
be the hypervisor constructing dom0 and all other domains would be constructed
by a toolstack, which would provide a SID. The introduction of dom0less and
subsequently hyperlaunch violates this assumption, as non-privileged domain may
be constructed before the initial domain or no initial domain may be
constructed at all. It is not possible currently for dom0less to express domain
labels in the domain configuration, as such the FLASK policy must employ a
sensible initial SID assignment that can differentiate between hypervisor and
toolstack domain construction.  With the introduction of xenboot_t it is now
possible to distinguish when the hypervisor is in the boot state, and thus any
domain construction happening at this time is being initiated by the
hypervisor.

This commit addresses the above situation by using a check to confirm if the
hypervisor is under the xenboot_t context in flask_domain_alloc_security().
When that is the case, it will inspect the domain's is_privileged field to
determine whether an initial label of dom0_t or domU_t should be set for the
domain. The logic for flask_domain_create() was changed to allow the incoming
SID to override the initial label.

The base policy was adjusted to allow the idle domain under the xenboot_t
context the ability to construct domains of both types, dom0_t and domu_t.

---

Split out from series "Adds starting the idle domain privileged", earlier patches
from series have been committed.

Changes in v12:
- actually send the changes from v11

Changes in v11:
- put back dom0_created variable in flask_domain_create() to ensure the
  enforcement that dom0_t is a singleton label

Changes in v10:
- rewrote commit message
- fixed typos
- reworked logic in flask_domain_create() to be simpler and not result in
  changing the domain security struct before the access check fails

That would about double the code in the functions. Imo all it takes
is to alter the while() conditions, prefixing what is there with
"seg == -1 &&".

Actually while looking there I've noticed the get_pseg() uses in
both functions aren't quite right for the "seg == -1" case either.
I'll make a patch there, which I think shouldn't collide with yours.

Hi Rahul,

This patch seems to have been sent in-reply-to the SMMUv1 patch. Was it 
intended?

It looks like this function was added without any callers. The commit 
message claim there will be some. Can you (or Oleksandr) confirm this is 
not going to be problem for future patches?

That said, I agree that the conversion pci -> dev -> pci is pointless. 
So I would say if there are use case where we only have a 'dev' in hand, 
then we could ask the caller to do the conversation or we provide an 
helper if there are too many cases.

While you are modifying the prototype for pci_find_host_bridge_node() 
can you consider to also constify the return (it should not be modified)?

In any case, the change suggested by Oleksandr should preferably be 
separate to this patch and added before.

Cheers,

When passed -1, the function (taking a u16) will look for segment
0xffff, which might exist. If it exists, we may find (return) the wrong
device.

An alternative would be to declare that both functions cannot be called
with "wildcards" anymore. The last such use went away with f591755823a7
("IOMMU/PCI: don't let domain cleanup continue when device de-assignment
failed") afaict.

Each time I look at this pair of functions I wonder why we have two
copies of almost the same code (with a curious difference of only one
having ASSERT(pcidevs_locked())). Any opinions on deleting either one,
subsuming its functionality into the other one by allowing the domain
pointer to be NULL to signify "any"?

One needs to run 'apt-get -qy upgrade' to upgrade the old packages so that
the missing dependent packages are also installed.

This is supposed to fix issues seen https://gitlab.com/xen-project/xen/-/jobs/2832045004
The failure is :-
root@4a175985cd71:/Users/ayankuma/alpine_vm/xen# apt-get -qy install --no-install-recommends u-boot-qemu u-boot-tools device-tree-compiler busybox-static cpio curl

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libc6-dev : Breaks: libglib2.0-dev (<= 2.72.3-1) but 2.70.2-1 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

For this we need to upgrade the packages which will resolve the dependencies.

The documentation for eIBRS has finally been clarified to state that it is
intended to flush the RSB on VMExit.  So in principle, we shouldn't have been
using opt_rsb_hvm on eIBRS hardware.

However, dropping the 32 entry RSB stuff makes us vulnerable to Post-Barrier
RSB speculation on affected Intel CPUs.

Introduce hvm_rsb_calculations() which selects between a 32-entry stuff, a
PBRSB specific workaround, or nothing, based on hardware details.

To mitigate PBRSB, put an LFENCE at the top of vmx_vmexit_handler().  This
forces the necessary safety property, without having to do a 1-entry RSB stuff
and fix up the stack(s) afterwards.

Update opt_rsb_hvm to be tristate.  On eIBRS-capable CPUs not susceptible to
PBRSB, this disables HVM RSB software protections entirely.  On eIBRS-capable
CPUs suceptible to to PBRSB, this reduces a 32-entry RSB stuff down to just
one LFENCE.

The PBRSB_NO bit indicates that the CPU is not vulnerable to the Post-Barrier
RSB speculative vulnerability.

Hi Rahul,

title: The driver is for both smmuv1 and v2. Are you suggesting the 
issue only occurs on v1?

AFAICT, this is fixing 0435784cc75d ("xen/arm: smmuv1: Intelligent SMR 
allocation"). If I am correct, can you add a Fixes tag?

IIUC, the function needs to be moved because you need to use 
arm_smmu_write_s2cr(). If so, I would suggest to mention in the commit 
message because at first it seems unwarranted.

NIT: I would suggest to take the opportunity to switch to "unsigned int" 
and ...

... use const here. "cfg" and "smmu" can't be consistent but 
"smmu_domain" technically could (thanks to how C works). That said, I 
quite dislike it as the code ends up to be confusing...

I think it would be clearer if this comment mentioned LFENCE like the
commit message does.  Looking at this change without the commit
message the connection is not obvious to me at least.  Maybe "we must
force one CALL instruction to retire (with LFENCE) before letting a
RET instruction execute"?

Refcounter itself is a good idea, but I'm not liking where all this
goes. We already are reworking locking by adding rw-locks with counters,
adding refcounter on top of this will complicate things even further.

I'm starting to think that complete PCI device locking rework may be
simpler solution, actually. By any chance, were there any prior
discussion on how proper locking should look like?=20

Thanks Ayan. The issue is that Debian unstable moved forward so now
apt-get fails. I updated the build container and the issue went away (I
rebuilt (automation/build/debian/unstable-arm64v8.dockerfile). So the
issue is gone for now.

In general, I don't know if it is a good idea to apply this patch: on
one hand it would make the script harder to break in the future next
time Debian moves forward, but I am concerned about additional
bandwidth and unnecessary upgrading done to packages for every test that
we run.

Subject: [PATCH 1/4] xen: x86: set the config XEN_512GB after config change
Date: Wed, 10 Aug 2022 07:07:09 +0200
Message-Id: <20220810050712.9539-2-lukas.bulwahn@gmail.com>
X-Mailer: git-send-email 2.17.1
In-Reply-To: <20220810050712.9539-1-lukas.bulwahn@gmail.com>
References: <20220810050712.9539-1-lukas.bulwahn@gmail.com>

Commit c70727a5bc18 ("xen: allow more than 512 GB of RAM for 64 bit
pv-domains") from July 2015 replaces the config XEN_MAX_DOMAIN_MEMORY with
a new config XEN_512GB, but misses to adjust arch/x86/configs/xen.config.

Adjust this config fragment now.

Subject: [PATCH 3/4] xen: move XEN_BALLOON_MEMORY_HOTPLUG to generic config
Date: Wed, 10 Aug 2022 07:07:11 +0200
Message-Id: <20220810050712.9539-4-lukas.bulwahn@gmail.com>
X-Mailer: git-send-email 2.17.1
In-Reply-To: <20220810050712.9539-1-lukas.bulwahn@gmail.com>
References: <20220810050712.9539-1-lukas.bulwahn@gmail.com>

While reviewing arch/x86/configs/xen.config, I noticed the following
note in this file:

  '# depends on MEMORY_HOTPLUG, arm64 doesn't enable this yet,
  '# move to generic config if it ever does.
  CONFIG_XEN_BALLOON_MEMORY_HOTPLUG=y

Commit 6c6685055a28 ("kconfig: add xenconfig defconfig helper") in June
2015 adds this note. Fortunately, commit 4ab215061554 ("arm64: Add memory
hotplug support") from December 2018 adds the memory hotplug in arm64, so
the precondition of this note above is now met.

Move setting the config XEN_BALLOON_MEMORY_HOTPLUG into the generic
xen.config now.

Subject: [PATCH 0/4] update the xen config fragments
Date: Wed, 10 Aug 2022 07:07:08 +0200
Message-Id: <20220810050712.9539-1-lukas.bulwahn@gmail.com>
X-Mailer: git-send-email 2.17.1

Dear xen maintainers,

here are three patches to update the xen config fragments to the currently
existing configs.

The fourth patch is just an addition to MAINTAINERS that I saw reasonable
after get_maintainers did not point to the XEN subsystem.

It applies cleanly on next-20220810.

Lukas

Lukas Bulwahn (4):
  xen: x86: set the config XEN_512GB after config change
  xen: remove XEN_SCRUB_PAGES in xen.config
  xen: move XEN_BALLOON_MEMORY_HOTPLUG to generic config
  MAINTAINERS: add xen config fragments to XEN HYPERVISOR sections

Subject: [PATCH 2/4] xen: remove XEN_SCRUB_PAGES in xen.config
Date: Wed, 10 Aug 2022 07:07:10 +0200
Message-Id: <20220810050712.9539-3-lukas.bulwahn@gmail.com>
X-Mailer: git-send-email 2.17.1
In-Reply-To: <20220810050712.9539-1-lukas.bulwahn@gmail.com>
References: <20220810050712.9539-1-lukas.bulwahn@gmail.com>

Commit 197ecb3802c0 ("xen/balloon: add runtime control for scrubbing
ballooned out pages") changed config XEN_SCRUB_PAGES to config
XEN_SCRUB_PAGES_DEFAULT. As xen.config sets 'XEN_BALLOON=y' and
XEN_SCRUB_PAGES_DEFAULT defaults to yes, there is no further need to set
this config in the xen.config file.

Remove setting XEN_SCRUB_PAGES in xen.config, which is without
effect since the commit above anyway.

I'm of quite the opposite opinion: A lot of the places will no longer
need to hold the pcidevs lock when instead they hold a reference; the
lock will only be needed to acquire a reference. Therefore refcounting
is likely to simplify things, presumably to the point where at least
recursive locking (and probably also converting to some r/w locking
scheme) won't be necessary. The main complicating factor is that all
places where a reference is needed will have to be located, and (quite
obviously I'm inclined to say) in particular all involved error paths
will need to be covered when it comes to dropping references no longer
needed.

Well, there were prior discussions (you'd need to search the list, as
I have no pointers to hand), but I'm not sure a clear picture had
surfaced how "proper locking" would look like. I guess that's part of
the reason why the currently proposed locking model actually makes
things quite a bit more complicated.

Besides the spelling issue mentioned by Jason I think this line also
wants wrapping. Maybe the two comments also want combining to just
one, such that "WARNING!" clearly applies to both parts.

Along the lines of half of what fdbf8bdfebc2 ("x86/spec-ctrl:
correct per-guest-type reporting of MD_CLEAR") did, I think you also want
to extend the other (earlier) conditional in this function invocation.

I also wonder whether it wouldn't be helpful to parenthesize the new
construct, such that it'll be more obvious that this is a double
conditional operator determining a single function argument.

Hmm, is SDM Vol 4's initial table wrong then in stating Kaby Lake /

... this? Otoh I notice that intel-family.h also says Skylake in
respective comments, despite the constants themselves being named
differently. Yet again ...

> +    case 0xa6: /* Comet Lake U62 */

... you call these Comet Lake when intel-family.h says Skylake also for
these (and names the latter's variable COMETLAKE_L).

What is in the comments here is of course not of primary concern for
getting this patch in, but the named anomalies will stand out when all
of this is switched over to use intel-family.h's constants.

For people using e.g. "spec-ctrl=no-ibrs" but leaving RSB stuffing enabled
(or force-enabling it) we'd need to have an LFENCE somewhere as well. Since
putting one in the RSB stuffing macro would require a runtime conditional
(for its use for alternatives patching), can't we leverage the one
controlled by this logic? That'll be a slight abuse of the name of
X86_BUG_PBRSB, but probably acceptable with a suitable comment. In the end
it'll simply be another fall-through, I guess:

        switch ( hvm_rsb )
        {
        case hvm_rsb_none:
            /* ... */
            fallthrough;

        case hvm_rsb_stuff32:
            setup_force_cpu_cap(X86_FEATURE_SC_RSB_HVM);

            /* ... */
            if ( boot_cpu_has(X86_FEATURE_SC_MSR_HVM) )
                break;
            fallthrough;
        case hvm_rsb_pbrsb:
            setup_force_cpu_cap(X86_BUG_PBRSB);
            break;
        }

That way, aiui, it also wouldn't get in the way of print_details(), which
checks X86_FEATURE_SC_RSB_HVM first.

Otoh I can see reasons why for the stuffing the LFENCE would really need
to live inside the macro, and in particular ahead of the RET there. Since
we don't want to have a runtime conditional there, I guess we should then,
as a fallback, extend the text in the command line doc to warn about the
inter-dependency. After all people "knowing what they are doing" doesn't
imply them knowing implementation details of Xen. But then I'd still be
a little concerned of the "they possibly know something we don't" case.

With there now being a CPUID field for this, let's try to avoid further
growing the set of family-specific "magic" numbers. Sadly on the boot
CPU it's too early to use the host policy, so an actual CPUID insn needs
to be issued. Let's take the opportunity though and make the extended
CPUID level available early.

Subject: [PATCH] xen/arm: vgic: Fix coding style in macro REG_RANK_INDEX()
Date: Wed, 10 Aug 2022 12:53:56 +0300
Message-Id: <20220810095356.1906405-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Add parentheses around the macro parameter 's' to prevent against unintended
expansions. This, also, resolves a MISRA C 2012 Rule 20.7 violation warning.

Add white spaces around the subtraction operator.

Subject: [PATCH] xen/arm: gic: Fix MISRA C 2012 Rule 20.7 violation
Date: Wed, 10 Aug 2022 13:15:39 +0300
Message-Id: <20220810101539.1909143-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1

In GIC_PRI_TO_GUEST(), add parentheses around the macro parameter 'pri' to
prevent against unintended expansions and realign comment.

Hi Xenia,

Thank for your effort to make Xen MISRA compliant. Personally, I find 
quite difficult to follow what's going on with dozen of single patches.

It is also makes more difficult for a committer to apply them. For 
instance, tools like 'b4' can easily apply a series. So there are less 
effort required.

So would you be able to try to batch your patches in larger series 
(maybe 10-20 patches)?

Cheers,

Refer "Arm Architecture Registers DDI 0595", AArch32 system registers,
CNTHP_CTL :- "When the value of the ENABLE bit is 1, ISTATUS indicates
whether the timer condition is met."

Also similar description applies to CNTP_CTL as well.

One should always check that the timer is enabled and status is set, to
determine if the timer interrupt has been generated.

This should either be a macro or be added directly into the condition.

But here seeing the rest of the code, I would suggest to create a macro for=
 the
whole condition and use it directly into the ifs as I find that this soluti=
on using
boolean variable is making the code unclear.

May I suggest the following:
#define CNTx_CTL_IS_PENDING(reg) (READ_SYSREG(reg) & (CNTx_CTL_PENDING | CN=
Tx_CTL_ENABLE))

Or in fact just adding CNTx_CTL_ENABLE in the if directly.

? True:false is redundant here and not needed.

Same here

This will return true even if either CNTx_CTL_PENDING or CNTx_CTL_ENABLE 
is set.

We want to check that both are set.

So this should be :-
#define CNTx_CTL_IS_PENDING(reg) ( (READ_SYSREG(reg) & (CNTx_CTL_PENDING | CNTx_CTL_ENABLE)) ==
(CNTx_CTL_PENDING | CNTx_CTL_ENABLE) )

Let me know if you agree. I will prefer using a macro rather putting this in 'if' condition as it might make readability difficult.

Hi Ayan,

Bertrand already made some comments. I will try to avoid repeating the
same comments.

On 10/08/2022 11:58, Ayan Kumar Halder wrote:

You are modifying code that is common between AArch64 and AArch32. So I 
would mention this behavior is common. Also, please specify the version
of the spec. This helps in case the behavior has changed.

Also, NIT: I would prefer if you quote the Arm Arm rather than auxiliary
specifications.

I think the key point here is the field ISTATUS is "unknown" when the 
ENABLE bit is 0.

I understand the theory. In practice, I am not sure this could ever 
happen because the timer interrupt is level and by clearing *_CTL you 
will lower the line and therefore you should not receive the interrupt 
again.

Checking the 'enable' is not going to add too much overhead. So I am 
fine if this is added. That said, would you be able to provide more 
details on how this was spotted?

Cheers,

From: Edwin Török <edvin.torok@citrix.com>

Following on from cset 9ce0a5e207f3 ("x86/hvm: Improve hvm_set_guest_pat()
code generation"), and the discovery that Clang/LLVM makes some especially
disastrous code generation for the loop at -O2

  https://github.com/llvm/llvm-project/issues/54644

Edvin decided to remove the loop entirely by fully vectorising it.  This is
substantially more efficient than the loop, and rather harder for a typical
compiler to mess up.

yes, this is the key thing.

This was spotted while debugging an unrelated problem while porting Xen 
on R52. For a different reason, I was not able to get context switch to 
work correctly.

When I was scrutinizing the timer_interrupt() with the documentation, I 
found that we are not checking ENABLE.

Although the code works fine today (on aarch32 or aarch64), I thought it 
is better to add the check for the sake of compliance with the 
documentation.

I can send the v2 patch (addressing yours and Bertrand's comment) if you 
think it is fine.

The main downside being that changing the code to fit in a new PAT
type will now be harder. I wonder in particular whether with that
in mind it wouldn't be better to express the check not in terms of
relations, but in terms of set / clear bits ("bits 3-7 clear AND
(bit 2 set OR bit 1 clear)"). The code kind of does so already, but
the variable names don't reflect that (and would hence need to
change in such an event).

While grep-ing for PAT_TYPE_ will hit this line, I think we want
every individual type to also be found here when grep-ing for one.
The actual values aren't going to change, but perhaps the beast
way to do so would still be by way of BUILD_BUG_ON()s.

This and the other constant want to gain UL suffixes. (While I'm
open to be convinced otherwise on the earlier two points, this one
I'm going to insist on. Yet in case it would end up being the only
change in need of making, it could of course be done while
committing.)

Thanks for the clarification. I am quite curious to know why you think 
our code is not compliant.

As I wrote before, when ENABLE is cleared, you should never have an 
interrupt because the timer interrupt is level. So I believe our code is 
compliant with the Arm Arm.

The only reason I am OK with checking ENABLE is because the overhead is 
limited. If this wasn't the case, then I think I would have wanted clear 
justification in the commit message *why* this is not compliant.

FWIW, Linux seems to use the same approach as us (see [1]). So, if you 
think this is not compliant, then maybe this is something you also want 
to consider to fix there?

Cheers,

Sorry I should have been clearer. I wasn't suggesting your understanding 
of the spec were wrong. In fact, it is correct and in theory we should 
check it.

I was pointing out that in practice I believe this is not necessary and 
our code is still compliant.

I also agree, this is not obvious from the code why we are compliant 
there are usually two ways to approach it:
   1) Add the extra check/barriers. The pros is the code is strictly 
compliant the cons is this could add overhead.
   2) Document it. The cons is we may be wrong and therefore end up in a 
unknown territory. In this case, this is mitigated by the fact the bit 
is "unknown" (and therefore I believe can never have a different 
meaning) and this will only trigger a "walk the list". That list would 
be empty if the timer is disabled.

You went with 1) and I am fine with that (I explained why before).

Cheers,

Subject: [PATCH v2 00/13] Intel Hardware P-States (HWP) support
Date: Wed, 10 Aug 2022 15:29:31 -0400

Hi,

This patch series adds Hardware-Controlled Performance States (HWP) for
Intel processors to Xen.

With HWP, the processor makes its own determinations for frequency
selection, though users can set some parameters and preferences.  There
is also Turbo Boost which dynamically pushes the max frequency if
possible.

The existing governors don't work with HWP since they select frequencies
and HWP doesn't expose those.  Therefore a dummy hwp-interal governor is
used that doesn't do anything.

xenpm get-cpufreq-para is extended to show HWP parameters, and
set-cpufreq-hwp is added to set them.

A lightly loaded OpenXT laptop showed ~1W power savings according to
powertop.  A mostly idle Fedora system (dom0 only) showed a more modest
power savings.

This for for a 10th gen 6-core 1600 MHz base 4900 MHZ max cpu.  In the
default balance mode, Turbo Boost doesn't exceed 4GHz.  Tweaking the
energy_perf preference with `xenpm set-cpufreq-hwp balance ene:64`,
I've seen the CPU hit 4.7GHz before throttling down and bouncing around
between 4.3 and 4.5 GHz.  Curiously the other cores read ~4GHz when
turbo boost takes affect.  This was done after pinning all dom0 cores,
and using taskset to pin to vCPU/pCPU 11 and running a bash tightloop.

In v2, I think I addressed all comments for v1.  I kept patch 11 "xenpm:
Factor out a non-fatal cpuid_parse variant", with a v2 comment
explaining why I keep it.

HWP defaults to disabled and running with the existing HWP configuration
- it doesn't reconfigure by default.  It can be enabled with
cpufreq=xen:hwp.

Hardware Duty Cycling (HDC) is another feature to autonomously powerdown
things.  It defaults to enabled when HWP is enabled, but HDC can be
disabled on the command line.  cpufreq=xen:hwp,no-hdc

I've only tested on 8th gen and 10th gen systems with activity window
and energy_perf support.  So the pathes for CPUs lacking those features
are untested.

Fast MSR support was removed in v2.  The model specific checking was not
done properly, and I don't have hardware to test with.  Since writes are
expected to be infrequent, I just removed the code.

This changes the systcl_pm_op hypercall, so that wants review.

Regards,
Jason

Subject: [PATCH v2 01/13] cpufreq: Allow restricting to internal governors only
Date: Wed, 10 Aug 2022 15:29:32 -0400
Message-Id: <20220810192944.102135-2-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
In-Reply-To: <20220810192944.102135-1-jandryuk@gmail.com>

For hwp, the standard governors are not usable, and only the internal
one is applicable.  Add the cpufreq_governor_internal boolean to
indicate when an internal governor, like hwp-internal, will be used.
This is set during presmp_initcall, so that it can suppress governor
registration during initcall.  Only a governor with a name containing
"-internal" will be allowed in that case.

This way, the unuseable governors are not registered, so they internal
one is the only one returned to userspace.  This means incompatible
governors won't be advertised to userspace.

Subject: [PATCH v2 02/13] cpufreq: Add perf_freq to cpuinfo
Date: Wed, 10 Aug 2022 15:29:33 -0400

acpi-cpufreq scales the aperf/mperf measurements by max_freq, but HWP
needs to scale by base frequency.  Settings max_freq to base_freq
"works" but the code is not obvious, and returning values to userspace
is tricky.  Add an additonal perf_freq member which is used for scaling
aperf/mperf measurements.

I don't like this, but it seems the best way to re-use the common
aperf/mperf code.  The other option would be to add wrappers that then
do the acpi vs. hwp scaling.

Export feature_detect as intel_feature_detect so it can be re-used by
HWP.

v2
export intel_feature_detect with typed pointer
Move intel_feature_detect to acpi/cpufreq/cpufreq.h since the
declaration now contains struct cpufreq_policy *.

>From the Intel SDM: "Hardware-Controlled Performance States (HWP), which
autonomously selects performance states while utilizing OS supplied
performance guidance hints."

Enable HWP to run in autonomous mode by poking the correct MSRs.
cpufreq=xen:hwp enables and cpufreq=xen:hwp=0 disables.  The same for
hdc.

There is no interface to configure - xen_sysctl_pm_op/xenpm will
be to be extended to configure in subsequent patches.  It will run with
the default values, which should be the default 0x80 (out
of 0x0-0xff) energy/performance preference.

Unscientific powertop measurement of an mostly idle, customized OpenXT
install:
A 10th gen 6-core laptop showed battery discharge drop from ~9.x to
~7.x watts.
A 8th gen 4-core laptop dropped from ~10 to ~9

Power usage depends on many factors, especially display brightness, but
this does show an power saving in balanced mode when CPU utilization is
low.

HWP isn't compatible with an external governor - it doesn't take
explicit frequency requests.  Therefore a minimal internal governor,
hwp-internal, is also added as a placeholder.

While adding to the xen-command-line.pandoc entry, un-nest verbose from
minfreq.  They are independent.

We disable on cpuid_level < 0x16.  cpuid(0x16) is used to get the cpu
frequencies for calculating the APERF/MPERF.  Without it, things would
still work, but the averge cpufrequency output would be wrong.

My 8th & 10th gen test systems both report:
(XEN) HWP: 1 notify: 1 act_window: 1 energy_perf: 1 pkg_level: 0 peci: 0
(XEN) HWP: Hardware Duty Cycling (HDC) supported
(XEN) HWP: HW_FEEDBACK not supported

IA32_ENERGY_PERF_BIAS has not been tested.

For cpufreq=xen:hwp, placing the option inside the governor wouldn't
work.  Users would have to select the hwp-internal governor to turn off
hwp support.  hwp-internal isn't usable without hwp, and users wouldn't
be able to select a different governor.  That doesn't matter while hwp
defaults off, but it would if or when hwp defaults to enabled.

We can't use parse_boolean() since it requires a single name=val string
and cpufreq_handle_common_option is provided two strings.  Use
parse_bool() and manual handle no-hwp.

Write to disable the interrupt - the linux pstate driver does this.  We
don't use the interrupts, so we can just turn them off.  We aren't ready
to handle them, so we don't want any.  Unclear if this is necessary.
SDM says it's default disabled.

FAST_IA32_HWP_REQUEST was removed in v2.  The check in v1 was wrong,
it's a model specific feature and the CPUID bit is only available
after enabling via the MSR.  Support was untested since I don't have
hardware with the feature.  Writes are expected to be infrequent, so
just leave it out.

---
v2:
Alphabetize headers
Re-work driver registration
name hwp_drv_data anonymous union "hw"
Drop hwp_verbose_cont
style cleanups
Condense hwp_governor switch
hwp_cpufreq_target remove .raw from hwp_req assignment
Use typed-pointer in a few functions
Pass type to xzalloc
Add HWP_ENERGY_PERF_BALANCE/IA32_ENERGY_BIAS_BALANCE defines
Add XEN_HWP_GOVERNOR define for "hwp-internal"
Capitalize CPUID and MSR defines
Change '_' to '-' for energy-perf & act-window
Read-modify-write MSRs updates
Use FAST_IA32_HWP_REQUEST_MSR_ENABLE define
constify pointer in hwp_set_misc_turbo
Add space after non-fallthrough break in governor switch
Add IA32_ENERGY_BIAS_MASK define
Check CPUID_PM_LEAK for energy bias when needed
Fail initialization with curr_req = -1
Fold hwp_read_capabilities into hwp_init_msrs
Add command line cpufreq=xen:hwp
Add command line cpufreq=xen:hdc
Use per_cpu for hwp_drv_data pointers
Move hwp_energy_perf_bias call into hwp_write_request
energy_perf 0 is valid, so hwp_energy_perf_bias cannot be skipped
Ensure we don't generate interrupts
Remove Fast Write of Uncore MSR
Initialize hwp_drv_data from curr_req
Use SPDX line instead of license text in hwp.c

Subject: [PATCH v2 05/13] xenpm: Change get-cpufreq-para output for internal
Date: Wed, 10 Aug 2022 15:29:36 -0400
Message-Id: <20220810192944.102135-6-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
In-Reply-To: <20220810192944.102135-1-jandryuk@gmail.com>
References: <20220810192944.102135-1-jandryuk@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

When using HWP, some of the returned data is not applicable.  In that
case, we should just omit it to avoid confusing the user.  So switch to
printing the base and turbo frequencies since those are relevant to HWP.
Similarly, stop printing the CPU frequencies since those do not apply.

v2:
Use full governor name XEN_HWP_GOVERNOR to change output
Style fixes

Subject: [PATCH v2 06/13] cpufreq: Export HWP parameters to userspace
Date: Wed, 10 Aug 2022 15:29:37 -0400
Message-Id: <20220810192944.102135-7-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
In-Reply-To: <20220810192944.102135-1-jandryuk@gmail.com>
References: <20220810192944.102135-1-jandryuk@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Extend xen_get_cpufreq_para to return hwp parameters.  These match the
hardware rather closely.

We need the features bitmask to indicated fields supported by the actual
hardware.

The use of uint8_t parameters matches the hardware size.  uint32_t
entries grows the sysctl_t past the build assertion in setup.c.  The
uint8_t ranges are supported across multiple generations, so hopefully
they won't change.

v2:
Style fixes
Don't bump XEN_SYSCTL_INTERFACE_VERSION
Drop cpufreq.h comment divider
Expand xen_hwp_para comment
Add HWP activity window mantissa/exponent defines
Handle union rename
Add const to get_hwp_para
Remove hw_ prefix from xen_hwp_para members
Use XEN_HWP_GOVERNOR
Use per_cpu for hwp_drv_data

Print HWP-specific parameters.  Some are always present, but others
depend on hardware support.

Signed-off-by: Jason Andryuk <jandryuk@gmail.com>

v2:
Style fixes
Declare i outside loop
Replace repearted hardware/configured limits with spaces
Fixup for hw_ removal
Use XEN_HWP_GOVERNOR
Use HWP_ACT_WINDOW_EXPONENT_*
Remove energy_perf hw autonomous - 0 doesn't mean autonomous

Subject: [PATCH v2 09/13] xen: Add SET_CPUFREQ_HWP xen_sysctl_pm_op
Date: Wed, 10 Aug 2022 15:29:40 -0400
Message-Id: <20220810192944.102135-10-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
In-Reply-To: <20220810192944.102135-1-jandryuk@gmail.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Add SET_CPUFREQ_HWP xen_sysctl_pm_op to set HWP parameters.  The sysctl
supports setting multiple values simultaneously as indicated by the
set_params bits.  This allows atomically applying new HWP configuration
via a single wrmsr.

XEN_SYSCTL_HWP_SET_PRESET_BALANCE/PERFORMANCE/POWERSAVE provide three
common presets.  Setting them depends on hardware limits which the
hypervisor is already caching.  So using them allows skipping a
hypercall to query the limits (lowest/highest) to then set those same
values.  The code is organized to allow a preset to be refined with
additional stuff if desired.

"most_efficient" and "guaranteed" could be additional presets in the
future, but the are not added now.  Those levels can change at runtime,
but we don't have code in place to monitor and update for those events.

Subject: [PATCH v2 11/13] xenpm: Factor out a non-fatal cpuid_parse variant
Date: Wed, 10 Aug 2022 15:29:42 -0400
Message-Id: <20220810192944.102135-12-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
In-Reply-To: <20220810192944.102135-1-jandryuk@gmail.com>
References: <20220810192944.102135-1-jandryuk@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Allow cpuid_parse to be re-used without terminating xenpm.  HWP will
re-use it to optionally parse a cpuid.  Unlike other uses of
cpuid_parse, parse_hwp_opts will take a variable number of arguments and
cannot just check argc.

v2:
Retained because cpuid_parse handles numeric cpu numbers and "all".

Subject: [PATCH v2 12/13] xenpm: Add set-cpufreq-hwp subcommand
Date: Wed, 10 Aug 2022 15:29:43 -0400

set-cpufreq-hwp allows setting the Hardware P-State (HWP) parameters.

It can be run on all or just a single cpu.  There are presets of
balance, powersave & performance.  Those can be further tweaked by
param:val arguments as explained in the usage description.

Parameter names are just checked to the first 3 characters to shorten
typing.

Some options are hardware dependent, and ranges can be found in
get-cpufreq-para.

Signed-off-by: Jason Andryuk <jandryuk@gmail.com>

v2:
Compare provided parameter name and not just 3 characters.
Use "-" in parameter names
Remove hw_
Replace sscanf with strchr & strtoul.
Remove toplevel error message with lower level ones.
Help text s/127/128/
Help text mention truncation.
Avoid some truncation rounding down by adding 5 before division.
Help test mention default microseconds
Also comment the limit check written to avoid overflow.

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:

Subject: [PATCH 1/3] golang/xenlight: Extend KeyedUnion to support Arrays
Date: Wed, 10 Aug 2022 15:48:25 -0400
Message-Id: <20220810194827.103428-2-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
In-Reply-To: <20220810194827.103428-1-jandryuk@gmail.com>
References: <20220810194827.103428-1-jandryuk@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Generation for KeyedUnion types doesn't support Arrays.  The smbios
support will place an smbios array inside the hvm KeyedUnion, and
gentotypes doesn't generate buildable Go code.

Have KeyedUnion add an idl.Array check and issue the approriate
xenlight_golang_array_to_C and xenlight_golang_array_from_C calls when
needed.  This matches how it is done in xenlight_golang_define_to_C &
xenlight_golang_define_from_C

xenlight_golang_array_to_C and xenlight_golang_array_from_C need to be
extended to set the cvarname and govarname as approriate for the
KeyedUnion cases to match the surrounding code.

Subject: [PATCH 0/3] libxl smbios support
Date: Wed, 10 Aug 2022 15:48:24 -0400
Message-Id: <20220810194827.103428-1-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

hvm_xs_strings.h specifies xenstore entries which can be used to set or
override smbios strings.  hvmloader has support for reading them, but
xl/libxl support is not wired up.  This patches adds a new xl.cfg option
and libxl support to write the xenstore strings.

The xl syntax looks like:
smbios=["bios_vendor=Xen Project","system_version=1.0"]

The Go binding generation needed extending to support Arrays inside a
KeyedUnion, which is what the first patch does.  The generated go code
builds, but it is otherwise untested.

There are also oem strings, oem-1..oem-99, that HVM loader supports.
The use of smbios_type Enum is a little unwieldy to defined so many
entries, but it works.  xl will internally parse smbios=["oem=A,oem=B"]
into oem_1 = "A" and oem_2 = "B".  xl still accepts oem_$N, though
hvmloader only reads sequentially from 1 up to a maximum of 99.  It's a
corner case what doesn't seem worth dealing with.

The rendered man page and html don't have a newline at then end of the
new section after patch 2.
"""
           battery_device_name=STRING
       ms_vm_genid="OPTION"
"""

however the txt format is correct:
"""
        battery_device_name=STRING

    ms_vm_genid="OPTION"
"""

It goes away after patch 3 is applied since it adds text about the "oem"
option in between the two lines above.  I'm at a loss as to why this is
happening.

Jason Andryuk (3):
  golang/xenlight: Extend KeyedUnion to support Arrays
  xl/libxl: Add ability to specify SMBIOS strings
  xl/libxl: Add OEM string support to smbios

Subject: [PATCH 2/3] xl/libxl: Add ability to specify SMBIOS strings
Date: Wed, 10 Aug 2022 15:48:26 -0400

hvm_xs_strings.h specifies xenstore entries which can be used to set or
override smbios strings.  hvmloader has support for reading them, but
xl/libxl support is not wired up.

Allow specifying the strings with the new xl.cfg option:
smbios=["bios_vendor=Xen Project","system_version=1.0"]

In terms of strings, the SMBIOS specification 3.5 says:
https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.5.0.pdf
"""
Strings must be encoded as UTF-8 with no byte order mark (BOM). For
compatibility with older SMBIOS parsers, US-ASCII characters should be
used.  NOTE There is no limit on the length of each individual text
string. However, the length of the entire structure table (including all
strings) must be reported in the Structure Table Length field of the
32-bit Structure Table Entry Point (see 5.2.1) and/or the Structure
Table Maximum Size field of the 64-bit Structure Table Entry Point (see
5.2.2).
"""

The strings aren't checked for utf-8 or length.  hvmloader has a sanity
check on the overall length.

The libxl_smbios_type enum starts at 1 since otherwise the 0th key is
not printed in the json output.

Subject: [PATCH 3/3] xl/libxl: Add OEM string support to smbios
Date: Wed, 10 Aug 2022 15:48:27 -0400
Message-Id: <20220810194827.103428-4-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.1
In-Reply-To: <20220810194827.103428-1-jandryuk@gmail.com>
References: <20220810194827.103428-1-jandryuk@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Add support for OEM strings in the SMBIOS type 11.

hvmloader checks them sequentially, so hide the implementation detail.
Allow multiple plain oem= items and assign the numeric values
internally.

Signed-off-by: Jason Andryuk <jandryuk@gmail.com>

This change re-introduces the newline before ms_vm_genid.

I hit similar issue, and the patch below made it work for me (ugly
workaround), or at least stop complaining.

But note one of those places have this comment:

	/* We need actual physical address instead of DMA address, since
	 * Trusted OS running on AMD Secure Processor will map this region
	 */

I guess it means AMD Secure Processor bypasses IOMMU...

    xen/arm: regs: Fix MISRA C 2012 Rule 20.7 violation
    
    In macro psr_mode(), the macro parameter 'm' is used as expression and

I don't see the difference - both use the same floating point format.
Whether you call it FP16 or half-precision is imo secondary. In fact the
new boolean might be usable for the F16C insns as well, if we wanted to.

Well, its the analogue of the space-0F encoded VCMPP{S,D} with the same
major opcode. I have to admit that it's unclear to me why you're asking.

No, why? It's VMOVW which first needs it (d8s_dq64 isn't really used
very much). I could have put _all_ such adjustments in a single prereq
patch, but it seemed better to me to make such changes at the point
where they're actually first needed, to make the connection with why
the change is needed in the first place.

What SrcImm / SrcImmByte are you talking about here? This twobyte_table[]
entry doesn't have such.

First of all this follows pre-existing code, where 0F38 is handled in a
similar manner. The primary reason for the two step approach though is
that we want to pick up the ModRM flag here, which the other table
doesn't have. Instead other tables might use its aliases (vSIB only for
now, which - yes - doesn't have a use yet in Map6, but this might
change going forward).

I also wonder why you comment on this here, but you didn't for patch 3,
where you've only asked that I add comments (which of course I will do).

Very good question. I've not been able to set, for myself, a good
threshold. The vague plan that I had was to wait and see what the next
uses in map 5/6 are going to be, and then decide whether to introduce
separate tables. (And if still going with overrides then, re-evaluate
on the subsequent set of additions. But basically always with a full
new set of insns in mind.)

>From all I can tell, the s->fp16 setting would better remain here, as
it's (embedded) prefix dependent. As are the disp8scale adjustments (if
you go look, you'll find similar pre-existing code a little higher up
in the file.)

Hmm, merely running the series there wouldn't mean much, as the code
doesn't usually come into play. My justification for going straight to
A was, as expressed in the description, that the new tests all pass on
SDE. Otherwise I think you're putting the bar too high for ever going
from a to A for such extensions where no new state is introduced, as
imo this would then mean proving that every single insn was actually
tested when taken through emulation.

Thanks (also for the other ones), but I'll wait with applying this one
until we've settled on the above.

Okay, will do that in v2. Rahul - this means there's no point anymore
sending a v2 of your fix, as the bug will disappear as a side effect.
I'll add you as the reporter of that bug.

With the "wildcard" support gone, that's going to be sensible, yes,
and I'll switch to that. Except for hwdom, where I mean to stick to
the per-segment all-devices lists, as on multi-segment systems these
are very likely the shorter lists, while on single-segment systems
the sole all-devices list likely isn't much longer than the list of
hwdom's devices (the delta being all devices [intended to be] passed
through plus all hidden devices). At this point I'm not sure whether
it would be worth further special-casing the single-segment case,
even if that's (on x86) the applicable one on the vast majority of
systems.

I don't think it's a hot path, but it can certainly be improved. Yet
that's future work, nothing to be done right here. But I'm inferring
you agree in this regard by saying "investigate".

Subject: [RFC net-next io_uring 04/11] net: shrink struct ubuf_info
Date: Wed, 10 Aug 2022 16:49:12 +0100
Message-Id: <1e2d0bef44cd68b0e3dd106283f4536645c2a124.1660124059.git.asml.silence@gmail.com>

We can benefit from a smaller struct ubuf_info, so leave only mandatory
fields and let users to decide how they want to extend it. Convert
MSG_ZEROCOPY to struct ubuf_info_msgzc and remove duplicated fields.
This reduces the size from 48 bytes to just 16.

We're going to split struct ubuf_info and leave there only
mandatory fields. Users are free to extend it. Add struct
ubuf_info_msgzc, which will be an extended version for MSG_ZEROCOPY and
some other users. It duplicates of struct ubuf_info for now and will be
removed in a couple of patches.

Subject: [RFC net-next io_uring 00/11] improve io_uring's ubuf_info refcounting
Date: Wed, 10 Aug 2022 16:49:08 +0100
Message-Id: <cover.1660124059.git.asml.silence@gmail.com>

There is a couple of tricks we can do with io_uring to improve ubuf_info
refcounting. First, we ammortise reference grabbing and then give them
away to the network layer, which is implemented in 8 and 11. Also, we
don't need need additional pinning for TCP, which is removed by 7.

1-4 are needed because otherwise we're out of space in io_notif_data and
using ->desc or some other field of ubuf_info would be ugly. It'll also
facilitate further ideas like adding a simpler notification model for UDP.

liburing/examples/io_uring-sendzc benchmark using a branch containing the
patchset and some more [1] showed ~1.6% qps improvement for UDP (dummy dev),
and ~1% for TCP (localhost + hacks enabling zc).

I didn't specifically test xen and vhost and not sure how, would love
some help with that.

[1] https://github.com/isilence/linux/tree/net/zc-ref-optimisation

Pavel Begunkov (11):
  net: introduce struct ubuf_info_msgzc
  xen/netback: use struct ubuf_info_msgzc
  vhost/net: use struct ubuf_info_msgzc
  net: shrink struct ubuf_info
  net: rename ubuf_info's flags
  net: add flags for controlling ubuf_info
  net/tcp: optimise tcp ubuf refcounting
  net: let callers provide ->msg_ubuf refs
  io_uring/notif: add helper for flushing refs
  io_uring/notif: mark notifs with UARGFL_CALLER_PINNED
  io_uring/notif: add ubuf_info ref caching

Add UARGFL_CALLER_PINNED letting protocols know that the caller holds a
reference to the ubuf_info and so it doesn't need additional refcounting
for purposes of keeping it alive. With that TCP can save a refcount
put/get pair per send when used with ->msg_ubuf.

There are already skb_flags in ubuf_info, which enhancing skbs. Also add
flags controlling ubuf_info, mainly to hint about various referencing
aspects of it, which will be introduced in later patches.

Subject: [RFC net-next io_uring 08/11] net: let callers provide ->msg_ubuf refs
Date: Wed, 10 Aug 2022 16:49:16 +0100

Some msg_ubuf providers like io_uring can keep elaborated ubuf_info
reference batching and caching, so it will be of benefit to let the
network layer to optionally steal some of the cached refs.

Add UARGFL_GIFT_REF, if set the caller has at least one extra reference
that it can gift away. If the network decides to take the ref it should
clear the flag.

Add a helper for dropping notification references during flush. It's a
preparation patch, currently it's only one master ref, but we're going
to add ref caching.

when we flush, so they're always pinned during sock_sendmsg() and we can
add UARGFL_CALLER_PINNED.

Cache some active notifier references at the io_uring side and get them
in batches, so the ammortised cost is low. Then these references can be
given away to the network layer using UARGFL_GIFT_REF.

Subject: [PATCH] x86/cpu: Drop _init from *_cpu_cap functions
Date: Thu, 11 Aug 2022 11:17:15 +0100
Message-ID: <20220811101715.3947873-1-ross.lagerwall@citrix.com>
X-Mailer: git-send-email 2.31.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Content-Type: text/plain

These functions may be called by init_amd() after the _init functions
have been purged during CPU hotplug or PV shim boot so drop the _init.

The two previously submitted bug fixes can actually be had as a side
effect of eliminating a bogus feature, the last use of which had
disappeared a while ago. Further cleanup then follows along the
lines of what had also been discussed in the context of the earlier
attempts.

1: simplify (and thus correct) pci_get_pdev{,_by_domain}()
2: fold pci_get_pdev{,_by_domain}()
3: bring pci_get_real_pdev() in line with pci_get_pdev()

The last "wildcard" use of either function went away with f591755823a7
("IOMMU/PCI: don't let domain cleanup continue when device de-assignment
failed"). Don't allow them to be called this way anymore. Besides
simplifying the code this also fixes two bugs:

1) When seg != -1, the outer loops should have been terminated after the
   first iteration, or else a device with the same BDF but on another
   segment could be found / returned.

Reported-by: Rahul Singh <rahul.singh@arm.com>

2) When seg == -1 calling get_pseg() is bogus. The function (taking a
   u16) would look for segment 0xffff, which might exist. If it exists,
   we might then find / return a wrong device.

In pci_get_pdev_by_domain() also switch from using the per-segment list
to using the per-domain one, with the exception of the hardware domain
(see the code comment there).

While there also constify "pseg" and drop "pdev"'s already previously
unnecessary initializer.

Rename the latter, subsuming the functionality of the former when passed
NULL as first argument.

Since this requires touching all call sites anyway, take the opportunity
and fold the remaining three parameters into a single pci_sbdf_t one.

No functional change intended. In particular the locking related
assertion needs to continue to be kept silent when a non-NULL domain
pointer is passed - both vpci_read() and vpci_write() call the function
without holding the lock (adding respective locking to vPCI [or finding
an alternative to doing so] is the topic of a separate series).

4.13, but yes. Oh well.

It's actually odd that we use __set_bit() for X86_FEATURE_MFENCE_RDTSC (a

Subject: [PATCH] x86/amd: Only call setup_force_cpu_cap for boot CPU

This should only be called for the boot CPU to avoid calling _init code
after it has been unloaded.

Fixes: 062868a5a8b4 ("x86/amd: Work around CLFLUSH ordering on older parts")
Signed-off-by: Ross Lagerwall <ross.lagerwall@citrix.com>

This replaces "x86/cpu: Drop _init from *_cpu_cap functions".

Commit 68f5aac012b9 ("build: suppress future GNU ld warning about RWX
load segments") didn't quite cover all the cases: Apparently I missed
ones in the building of 32-bit helper objects because of only looking at
incremental builds (where those wouldn't normally be re-built). Clone
the workaround there to the specific Makefile in question.

Because of the use of LDFLAGS_DIRECT (coming directly from the Config.mk
helpers in config/) having a central place to set this once isn't very
easy: An option might be to introduce XEN_LDFLAGS_DIRECT and export that
from where the other XEN_*FLAGS are also exported. The way it's done
here is the less intrusive variant, though.

It's not clear why for x86-64 a different approach was used than the
(shorter) one x86-32 has been using. Move the LDFLAGS_DIRECT_*BSD
setting to the respective OS files and reuse x86-32's approach for
x86-64.

I was actually inclined to go further and rename the variable(s) as
well, to e.g. XEN_ELF_SUB_FLAVOR, at the same time eliminating the
indirection via $(XEN_OS).

No, I don't think we can mention drivers support, we don't test any, it
would be incomplete, and we can't do anything if a driver is broken.
I've put "hda" first on the list in the hope that if someone wants a
sound card but don't know which one to use, they will try this one
first.

Thanks,

No, I'm strictly against introducing a 2nd instance of such aliasing
(we already have one in struct pci_dev, and that's bad enough). There
could be _only_ an "sbdf" field here, yes, but that'll have knock-on
effects elsewhere, so wants to be a separate change. And there are far
more places where imo we'll want to use pci_sbdf_t.

Yeah, I'm sorry about that. I'll add a comment describing what's going on.

I see that someone obviously has asked the same questions about the
OP-TEE mediator in the TEE mediator framework. I'll try the same
approach with limit etc since I guess the use-case there and here at
least initially will be similar.

Thanks for your quick response.

I took time to look into the code, below are my conclusions.

For a normal UEFI boot flow, UEFI will invoke Linux kernel's EFI stub,
and the EFI stub will install MEMRESERVE EFI configuration table.
This is accomplished in the Linux function install_memreserve_table().

Secondly, Xen passes DT to kernel, it synthesizes ACPI compatible
nodes in the device tree and finally kernel parses DT and create the
ACPI table.  In this case, Xen doesn't invoke Linux EFI stub.

To be honest, I have very less knowledge for Xen and APCI; just based on
reading code, I think it's hard for Xen to invoke Linux kernel's EFI
stub, this is because Xen needs to provide the EFI runtime services, and
I don't think it's feasible for Xen to pass through UEFI's runtime
service to Linux kernel.  If we implement the EFI runtime services for
Xen, then this would introduce a big implementation.

So another option is we simply add MEMRESERVE EFI configuration table
into device tree, just like Xen does for other ACPI tables (e.g.
RSDP?).  And then in Linux kernel, we need to parse the DT binding and
initialize the corresponding variables in kernel, so we need to add
support in the Linux source drivers/firmware/efi/fdtparams.c.

Before I proceed, just want to check which option would be the right
way to move forward?  And I am open for any other solution and welcome
suggestions.

Thanks a lot!
Leo

When Xen is started using EFI, Linux is then started purely using device tr=

there is a standard way to define reserved memory to linux using the device
tree and Xen should decode the Memreserve entry from EFI and add the
corresponding entry in the device tree that we give to linux.

This is not what MEMRESERVE is used for. Specifying reservations for
the current boot is straight-forward. What MEMRESERVE does is specify
a reservation that survives kexec and is passed on to the next
kernel(s), as the table is anchored in a structure that is created by
the EFI stub on the first boot. This is needed for the GICv3 on some
platforms, as memory that Linux reserves for its interrupt tables can
never be released again, even across kexec, which means that the GICv3
will be DMA'ing into that memory if the kexec kernel wants it or not)

I'd strongly recommend against doing any of the things Xen does for
ACPI boot today: both the ACPI spec and the kernel documentation about
ACPI support in the arm64 port is 100% clear that EFI boot is the only
supported boot method. Issues like this one would have never popped up
if those rules were adhered to. (/pedantic mode off)

In your case, this is a matter of allocating a structure of the right
type and size, and making it available via the configuration table
array in the EFI system table that the dom0 kernel receives from Xen
at boot.

Please don't add DT entries for this - we should be able to cover this
using the existing pseudo-EFI boot flow that Xen uses today.

I agree with that in the long term we should find a solution to remove this
system and have something more compliant with EFI/ACPI in Xen.

Currently the EFI system table is passed using a device tree generated
by Xen. To add support right now we would need to make the table
available to dom0 and pass its address inside this device tree.

Well, I can try to get to making a patch tomorrow, just in time to meet
the submission deadline. But that's not really a promise ...

Subject: [PATCH v2] xen/arm: smmu: Set s2cr to type fault when the devices are deassigned
Date: Thu, 11 Aug 2022 16:42:04 +0100
Message-Id: <3d254f1c7045bc212c5700c1becde458174e5bf3.1660232299.git.rahul.singh@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

When devices are deassigned/assigned, SMMU global fault is observed
because SMEs are freed in detach function and not allocated again when
the device is assigned back to the guest.

Don't free the SMEs when devices are deassigned, set the s2cr to type
fault. This way the SMMU will generate a fault if a DMA access is done
by a device not assigned to a guest.

Remove the arm_smmu_master_free_smes() as this is not needed anymore,
arm_smmu_write_s2cr will be used to set the s2cr to type fault.

Fixes: 0435784cc75d ("xen/arm: smmuv1: Intelligent SMR allocation")
Signed-off-by: Rahul Singh <rahul.singh@arm.com>
---
Changes in v2:
 - fix minor comment in commit msg and added fixes tag.
 - make smmu_domain const in function arm_smmu_domain_remove_master
 - remove return in arm_smmu_detach_dev

Subject: [PATCH] x86/msi: Switch msi_info to using pci_sbdf_t
Date: Thu, 11 Aug 2022 17:37:40 +0100

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

This reorders the fields in msi_info, but removes all the under-the-hood
parameter shuffling required to call pci_get_pdev().

No functional change.

gdbsx/:
  - Make use of subdir facility for the "clean" target.
  - No need to remove the *.a, they aren't in this dir.
  - Avoid calling "distclean" in subdirs as "distclean" targets do only
    call "clean", and the "clean" also runs "clean" in subdirs.
  - Avoid the need to make "gx_all.a" and "xg_all.a" in the "all"
    recipe by forcing make to check for update of "xg/xg_all.a" and
    "gx/gx_all.a" by having "FORCE" as prerequisite. Now, when making
    "gdbsx", make will recurse even when both *.a already exist.
  - List target in $(TARGETS).

gdbsx/*/:
  - Fix dependency on *.h.
  - Remove some dead code.
  - List targets in $(TARGETS).
  - Remove "build" target.
  - Cleanup "clean" targets.
  - remove comments about the choice of "ar" instead of "ld"
  - Use "$(AR)" instead of plain "ar".

Notes:
    v2:
    - also replace plain "ar" by "$(AR)"

Patch series available in this git branch:
https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.toolstack-build-system-v4

Changes in v4:
- several new patches
- some changes to other patches listed in their changelogs

Changes in v3:
- rebased
- several new patches, starting with 13/25 "tools/libs/util: cleanup Makefile"
- introducing macros to deal with linking with in-tree xen libraries
- Add -Werror to CFLAGS for all builds in tools/

Changes in v2:
- one new patch
- other changes described in patch notes

Hi everyone,

I've been looking at reworking the build system we have for the "tools/", and
transforming it to something that suit it better. There are a lot of
dependencies between different sub-directories so it would be nice if GNU make
could actually handle them. This is possible with "non-recursive makefiles".

With non-recursive makefiles, make will have to load/include all the makefiles
and thus will have complete overview of all the dependencies. This will allow
make to build the necessary targets in other directory, and we won't need to
build sub-directories one by one.

To help with this transformation, I've chosen to go with a recent project
called "subdirmk". It help to deal with the fact that all makefiles will share
the same namespace, it is hooked into autoconf, we can easily run `make` from
any subdirectory. Together "autoconf" and "subdirmk" will also help to get
closer to be able to do out-of-tree build of the tools, but I'm mainly looking
to have non-recursive makefile.

Link to the project:
    https://www.chiark.greenend.org.uk/ucgi/~ian/git/subdirmk.git/

But before getting to the main course, I've got quite a few cleanup and some
changes to the makefiles. I start the patch series with patches that remove old
left over stuff, then start reworking makefiles. They are some common changes like
removing the "build" targets in many places as "all" would be the more common
way to spell it and "all" is the default target anyway. They are other changes
related to the conversion to "subdirmk", I start to use the variable $(TARGETS)
in several makefiles, this variable will have a special meaning in subdirmk
which will build those target by default.

As for the conversion to non-recursive makefile, with subdirmk, I have this WIP
branch, it contains some changes that I'm trying out, some notes, and the
conversion, one Makefile per commit. Cleanup are still needed, some makefile
not converted yet, but it's otherwise mostly done.

    https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.toolstack-build-system-v1-wip-extra

With that branch, you could tried something like:
    ./configure; cd tools/xl; make
and `xl` should be built as well as all the xen library needed.
Also, things like `make clean` or rebuild should be faster in the all tools/
directory.

Cheers,

Remove the need for "fs-*" targets by creating a "common.mk" which
have flags that are common to libfsimage/common/ and the other
libfsimages/*/ directories.

In common.mk, make $(PIC_OBJS) a recursively expanded variable so it
doesn't matter where $(LIB_SRCS-y) is defined, and remove the extra
$(PIC_OBJS) from libfsimage/common/Makefile.

Use a $(TARGETS) variable to list things to be built. And $(TARGETS)
can be use in the clean target in common.mk.

iso9660/:
    Remove the explicit dependency between fsys_iso9660.c and
    iso9660.h, this is handled automaticaly by the .*.d dependency files,
    and iso9660.h already exist.

Setup proper dependencies with libacpi so we don't need to run "make
hvmloader" in the "all" target. ("build.o" new prerequisite isn't
exactly proper but a side effect of building the $(DSDT_FILES) is to
generate the "ssdt_*.h" needed by "build.o".)

Make use if "-iquote" instead of a plain "-I".

For "roms.inc" target, use "$(SHELL)" instead of plain "sh". And use
full path to "mkhex" instead of a relative one. Lastly, add "-f" flag
to "mv" to avoid a prompt in case the target already exist and we
don't have write permission.

Notes:
    v4:
    - fix reason for 'mv -f' in patch description.
    - add a comment about build.o's new prerequisites.

Remove "build" targets.

Use simply expanded variables when recursively expanded variable
aren't needed. (Use ":=" instead of "=".)

Don't check if a directory already exist when installing, just create
it.

Fix $(HOTPLUGPATH), it shouldn't have any double-quote.

Some reindentation.

FreeBSD, "hotplugpath.sh" is already installed by common/.

Add "xentop" to "TARGETS" because this variable will be useful later.

Always define all the targets, even when configured with
--disable-monitor, instead don't visit the subdirectory.
This mean xentop/ isn't visited anymore during "make clean" that's how
most other subdirs in the tools/ works.

Also add missing "xentop" rules. It only works without it because we
still have make's built-ins rules and variables, but fix this to not
have to rely on them.

Use $(TARGETS) with $(INSTALL_PROG), and thus install into the
directory rather than spelling the program name.

In the "clean" rule, use $(RM) and remove all "*.o" instead of just
one object.

Notes:
    v2:
    - use $(RM) in clean.
    - remove all *.o instead of just one object in "clean" rule.
    - in "install" rule, make use of $(TARGETS). install into a dir rather
      than to a specific path, in case there's more targets.

Rework dependencies of all objects. We don't need to add dependencies
for headers that $(CC) is capable of generating, we only need to
include $(DEPS_INCLUDE). Some dependencies are still needed so make
knows to generate symlinks for them.

We remove the use of "vpath" for cpuid.c. While it works fine for now,
when we will convert this makefile to subdirmk, vpath will not be
usable. Also, "-iquote" is now needed to build "cpuid.o".

Replace "-I." by "-iquote .", so it applies to double-quote includes
only.

Rather than checking if a symlink exist, always regenerate the
symlink. So if the source tree changed location, the symlink is
updated.

Since we are creating a new .gitignore for the symlink, also move the
entry to it.

    v4:
    - Use pattern rules to link sources from libx86 and from x86 emulator
      tests
    - fix rm of .*.d2 dependency files
    
    v2:
    - create a new per-directory .gitignore to add the new entry and existing ones

There is no need to call the "headers.chk" target when it isn't
wanted, so it never need to be .PHONY.

Also, there is no more reason to separate the prerequisites from the
recipe.

Subject: [XEN PATCH v4 15/32] tools: Introduce $(xenlibs-rpath,..) to replace $(SHDEPS_lib*)
Date: Thu, 11 Aug 2022 17:48:28 +0100

This patch introduce a new macro $(xenlibs-dependencies,) to generate
a list of all the xen library that a library is list against, and they
are listed only once. We use the side effect of $(sort ) which remove
duplicates.

This is used by another macro $(xenlibs-rpath,) which is to replace
$(SHDEPS_libxen*).

In libs.mk, we don't need to $(sort ) SHLIB_lib* anymore as this was used
to remove duplicates and they are no more duplicates.

Subject: [XEN PATCH v4 30/32] libs/light: Rework targets prerequisites
Date: Thu, 11 Aug 2022 17:48:43 +0100

No need for $(AUTOSRCS), GNU make can generate them as needed when
trying to build them as needed when trying to build the object. Also,
those two AUTOSRCS don't need to be a prerequisite of "all". As for
the "clean" target, those two files are already removed via "_*.c".

We don't need $(AUTOINCS) either:
- As for both _libxl_savm_msgs*.h headers, we are adding more
  selective dependencies so the headers will still be generated as
  needed.
- "clean" rule already delete the _*.h files, so AUTOINCS aren't needed
  there.

"libxl_internal_json.h" doesn't seems to have ever existed, so the
dependency is removed.

Add few prerequisite for "libxl_internal.h" so all headers that it
depends on should be generated. And have $(SAVE_HELPER_OBJS) depends
on "libxl_internal.h".

Rework objects prerequisites, to have them dependents on either
"libxl.h" or "libxl_internal.h". "libxl.h" is not normally included
directly in the source code as "libxl_internal.h" is used instead. But
we are adding "libxl.h" as prerequisite of "libxl_internal.h", so
generated headers will still be generated as needed.

"testidl.c" doesn't depends on "libxl.h" but "testidl.o" does. Also
use automatic variables $< and $@.

Subject: [XEN PATCH v4 25/32] libs: Avoid exposing -Wl,--version-script to other built library
Date: Thu, 11 Aug 2022 17:48:38 +0100
Message-ID: <20220811164845.38083-26-anthony.perard@citrix.com>

In-Reply-To: <20220811164845.38083-1-anthony.perard@citrix.com>

$(SHLIB_LDFLAGS) is used by more targets that the single targets that
except it (libxenfoo.so.X.Y). There is also some dynamic libraries in
stats/ that uses $(SHLIB_LDFLAGS) (even if those are never built), and
there's libxenlight_test.so which doesn't needs a version script.

Also, libxenlight_test.so might failed to build if the version script
doesn't exist yet.

For these reasons, avoid changing the generic $(SHLIB_LDFLAGS) flags,
and add the flag directly on the command line.

Subject: [XEN PATCH v4 27/32] tools/include: Rework Makefile
Date: Thu, 11 Aug 2022 17:48:40 +0100

Rework "xen-xsm" rules to not have to change directory to run
mkflask.sh, and store mkflask.sh path in a var, and use a full path
for FLASK_H_DEPEND, and output directory is made relative.

Rename "all-y" target to a more descriptive "xen/lib/x86/all".

Removed the "dist" target which was the only one existing in tools/.

Remove "build" targets.

Use "$(TARGETS)" to list binary to be built.

Cleanup "clean" rule.

Also drop conditional install of $(BIN) and $(LIBBIN) as those two
variables are now always populated.

Signed-off-by: Anthony PERARD <anthony.perard@citrix.com>

Notes:
    v4:
    - also use := for BIN, SBIN, LIBBIN, SCRIPTS
    
    v2:
    - fix typo in title
    - drop conditional install of $(BIN) and $(LIBBIN)

Subject: [XEN PATCH v4 28/32] libs/light: Rework acpi table build targets
Date: Thu, 11 Aug 2022 17:48:41 +0100

Currently, a rebuild of libxl will always rebuild for example
"build.o". This is because the target depends on "acpi" which never
exist. So instead we will have "build.o" have as prerequisites targets
that are actually generated by "acpi", that is $(DSDT_FILES-y).

While "dsdt_*.c" isn't really a dependency for "build.o", a side
effect of building that dsdt_*.c is to also generate the "ssdt_*.h"
that "build.o" needs, but I don't want to list all the headers needed
by "build.o" and duplicate the information available in
"libacpi/Makefile" at this time.

Also avoid duplicating the "acpi" target for Arm, and unique one for
both architecture. And move the "acpi" target to be with other targets
rather than in the middle of the source listing. For the same reason,
move the prerequisites listing for both $(DSDT_FILES-y) and "build.o".

Subject: [XEN PATCH v4 32/32] tools/golang/xenlight: Rework gengotypes.py and generation of *.gen.go
Date: Thu, 11 Aug 2022 17:48:45 +0100

gengotypes.py creates both "types.gen.go" and "helpers.gen.go", but
make can start gengotypes.py twice. Rework the rules so that
gengotypes.py is executed only once.

Also, add the ability to provide a path to tell gengotypes.py where to
put the files. This doesn't matter yet but it will when for example
the script will be run from tools/ to generate the targets.

Rework "libacpi.h" include in "libxl_x86_acpi.c" as to be more
selective about the include path and only add "tools/libacpi/". Also
"libxl_dom.c" don't use "libacpi.h" anymore. Use "-iquote" for libacpi
headers.

Get rid of the weird "$(eval stem =" in the middle of a recipe and use
a make automatic variable "$(*F)" instead.

Use $(TARGETS) to collect targets. Use := for the first target instead
of +=.
Collect library to link against in $(LDLIBS).
Remove extra "-f" flags that is already part of $(RM).

    v4:
    - use := for the first TARGETS
    v3:
    - apply changes to the new "init-dom0less" helper.
    - make use of the new macro $(xenlibs-ldlibs,)

"$DIR" might not be a full path and it might not have `pwd` as ".."
directory. So use `cd -` to undo the first `cd` command.

Also, use `basename` to make a symbolic link with a relative path.

This doesn't matter yet but it will when for example the commands to
clone OVMF is been run from tools/ rather than tools/firmware/.

Subject: [XEN PATCH v4 26/32] libs: Fix auto-generation of version-script for unstable libs
Date: Thu, 11 Aug 2022 17:48:39 +0100
Message-ID: <20220811164845.38083-27-anthony.perard@citrix.com>

When there isn't a version-script for a shared library (like for
unstable libs), we create one based on the current Xen version. But
that version-script became out-of-date as soon as Xen's version
changes and make as no way to regenerate the version-script on
rebuild.

In order to allow regenerating the script, we'll have a different
filename. In order to check if the content is up-to-date, we'll always
generated it and compare.

But we also need to know if there's already an existing version script
or if we need to generate one, for that we introduce $(version-script)
to be used to point to the path of the existing script. (Guessing if a
version script exist for a stable library with for example $(wildcard)
won't work as a file will exist when building the library without this
patch.)

We don't need the version-script unless we are making the shared
library so it is removed from the "all" target.

Alternatively, we could remove the need for to generate a
version-script, but that would mean the exported symbols won't have a
version anymore (like before, a few versions of Xen ago). Or, we could
use --default-symver, but the symboled would be versionned with the
soname (e.g. "libxenctrl.so.4.16.0") instead of "VERS_4.16.0".

Subject: [XEN PATCH v4 29/32] libs/light: Rework generation of include/_libxl_*.h
Date: Thu, 11 Aug 2022 17:48:42 +0100
Message-ID: <20220811164845.38083-30-anthony.perard@citrix.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Content-Type: text/plain

Instead of moving the public "_libxl_*.h" headers, we make a copy to
the destination so that make doesn't try to remake the targets
"_libxl_*.h" in libs/light/ again.

A new .PRECIOUS target is added to tell make to not deletes the
intermediate targets generated by "gentypes.py".

Subject: [XEN PATCH v4 16/32] tools: Introduce $(xenlibs-ldlibs, ) macro

This can be used when linking against multiple in-tree Xen libraries,
and avoid duplicated flags. It can be used instead of multiple
$(LDLIBS_libxen*).

For now, replace the open-coding in libs.mk.

The macro $(xenlibs-libs, ) will be useful later when only the path to
the libraries is wanted (e.g. for checking for dependencies).

Subject: [PATCH 2/2] templates/linux_xen: Properly order the multiple initrd files
Date: Thu, 11 Aug 2022 16:10:14 -0300
Message-Id: <20220811191014.139882-3-mfo@canonical.com>

The linux_xen template orders the "early" initrd file(s) _first_
(i.e., before the "real" initrd files) and that seems reasonable,
as microcode updates usually come first.

However, this usually breaks Linux boot with initrd under Xen
because Xen assumes the real initrd is the first multiboot[2]
module after the kernel, passing its address over to Linux in
Xen's start_info struct.

So, if a microcode-only initrd (i.e., without init/userspace)
is found by grub-mkconfig, it ends up considered as a normal
initrd by the Linux kernel, which cannot do anything with it
(as it has no other files) and panic()s unable to mount root
if it depends on a initrd to do that (e.g., root=UUID=...).

...

Well, since Xen doesn't actually use the provided microcode
by default / unless the 'ucode=<module number|scan>' option
is enabled, this isn't used in the general case (and breaks).

Additionally, if an user enables the 'ucode=' option, that
either specifies which module is to be used for microcode,
or scans all modules (regardless of being first) for that.

Thus, for Xen:
- it is *not required* to have microcode first,
- but it is *required* to have real initrd first

So, fix it by ordering the real initrd before early initrd(s).

After:

    # touch /boot/xen /boot/microcode.cpio
    # grub-mkconfig 2>/dev/null | grep -P '^\t(multiboot|module)'
            multiboot      /boot/xen ...
            module  /boot/vmlinuz-5.4.0-122-generic ...
            module  --nounzip   /boot/initrd.img-5.4.0-122-generic
            module  --nounzip   /boot/microcode.cpio

...

Corner case specific to Xen implementation details:

It is actually _possible_ to have a microcode initrd first,
but that requires a non-default option (so can't rely on it),
and it turns out to be inconsistent with its counterpart
(really shouldn't rely on it, as it may get confusing; below).

'ucode=1' does manually specify the first module is microcode
_AND_ clears its bit in the module bitmap. The next module is
now the 'new first', and gets passed to Linux as initrd. Good.

'ucode=scan' checks all modules for microcode, but does _NOT_
clear a bit if it finds one (reasonable, as it can find that
prepended in a "real" initrd anyway, which needs to be used).
The first module still gets passed to Linux as initrd. Bad.

Subject: [PATCH 1/2] templates/linux_xen: Properly load multiple initrd files
Date: Thu, 11 Aug 2022 16:10:13 -0300

The linux_xen template can put multiple initrd files in the
same multiboot[2] module[2] command, which is against specs.

This causes ONLY the _first_ initrd file to be loaded; other
files just have filenames in a "cmdline" string of the first
initrd file and are NOT loaded.

Fix this by inserting a module[2] command per initrd file.

Before:

    # touch /boot/xen /boot/microcode.cpio
    # grub-mkconfig 2>/dev/null | grep -P '^\t(multiboot|module)'
            multiboot       /boot/xen ...
            module  /boot/vmlinuz-5.4.0-122-generic ...
            module  --nounzip   /boot/microcode.cpio /boot/initrd.img-5.4.0-122-generic

After:

    # touch /boot/xen /boot/microcode.cpio
    # grub-mkconfig 2>/dev/null | grep -P '^\t(multiboot|module)'
            multiboot      /boot/xen ...
            module  /boot/vmlinuz-5.4.0-122-generic ...
            module  --nounzip   /boot/microcode.cpio
            module  --nounzip   /boot/initrd.img-5.4.0-122-generic

Cause:

The code was copied from the linux template, which is *apparently*
equivalent.. but its initrd command grub_cmd_initrd() *supports*
multiple files (see grub_initrd_init()), while module/module2 in
grub_cmd_module() *does not* (see grub_multiboot[2]_add_module()).

See commit e86f6aafb8de ("grub-mkconfig/20_linux_xen: Support multiple early initrd images"):
    'This is basically a copy of a698240d "grub-mkconfig/10_linux:
     Support multiple early initrd images" ...'

Specs:

Both multiboot and multiboot2 specifications mention support for
'multiple boot modules' (struct/tag used for kernel/initrd files):

    "Boot loaders don’t have to support multiple boot modules,
     but they are strongly encouraged to" [1,2]

However, there is a 1:1 relationship between boot modules and files,
more or less clearly; note the usage of singular/plural "module(s)".
(Multiboot2, clearly: "One tag appears per module".)

  Multiboot [1]:

    "the ‘mods’ fields indicate ... what boot modules
     were loaded ..., and where they can be found.
     ‘mods_count’ contains the number of modules loaded"

    "The first two fields contain the start and end addresses
     of the boot module itself."

  Multiboot2 [2]:

    "This tag indicates ... what boot module was loaded ...,
     and where it can be found."

    "The ‘mod_start’ and ‘mod_end’ contain the start and end
     physical addresses of the boot module itself."

    "One tag appears per module.
     This tag type may appear multiple times."

And both clearly mention the 'string' field of a boot module,
which is to be used by the operating system, not boot loader:

     "The ‘string’ field provides an arbitrary string to be
      associated with that particular boot module ...
      its exact use is specific to the operating system."

Thanks,

The linux_xen template seems to be broken for multiple initrd files.
Linux fails to boot when it needs a real initrd but early/microcode
initrd(s) are found by grub-mkconfig.

Patch 1 allows initrd(s) other than the first early/microcode initrd
to be loaded at all, fixing an implementation error for multiboot[2].

Patch 2 allows Linux to get the real initrd as initrd (vs. an early/
microcode-only initrd), thus being able to boot if it needs a initrd.

Synthetic tests:
---

    # touch /boot/xen /boot/microcode.cpio

Original:

    # grub-mkconfig 2>/dev/null | grep -P '^\t(multiboot|module)'
            multiboot       /boot/xen ...
            module  /boot/vmlinuz-5.4.0-122-generic ...
            module  --nounzip   /boot/microcode.cpio /boot/initrd.img-5.4.0-122-generic

Patch 1:

    # grub-mkconfig 2>/dev/null | grep -P '^\t(multiboot|module)'
            multiboot      /boot/xen ...
            module  /boot/vmlinuz-5.4.0-122-generic ...
            module  --nounzip   /boot/microcode.cpio
            module  --nounzip   /boot/initrd.img-5.4.0-122-generic

Patch 2:

    # grub-mkconfig 2>/dev/null | grep -P '^\t(multiboot|module)'
            multiboot      /boot/xen ...
            module  /boot/vmlinuz-5.4.0-122-generic ...
            module  --nounzip   /boot/initrd.img-5.4.0-122-generic
            module  --nounzip   /boot/microcode.cpio

    With fake multiboot2 header:

    # echo -en '\xd6\x50\x52\xe8\x00\x00\x00\x00' > /boot/xen
    # echo -en '\x00\x00\x00\x00\x2a\xaf\xad\x17' >> /boot/xen
    # echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' >> /boot/xen
    # echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' >> /boot/xen

    # grub-file --is-x86-multiboot2 /boot/xen; echo $?
    0
    
    # grub-mkconfig 2>/dev/null | grep -P '^\t(multiboot|module)'
            multiboot2      /boot/xen ...
            module2 /boot/vmlinuz-5.4.0-122-generic ...
            module2 --nounzip   /boot/initrd.img-5.4.0-122-generic

Subject: [PATCH 2/2] x86/svm: Keep the RAS balanced for guests
Date: Thu, 11 Aug 2022 20:59:05 +0100

One source of lost performance was that fact that to protect Xen from a
malicious guests, we had to flush the RAS.

It turns out that CET Shadow Stacks give us enough architectural guarantees to
construct a lower overhead mitigation, which keeps the RAS balanced for the
guest so their return performance is still good.

To keep the RAS balanced, Xen must execute the same number of CALLs as RETs
across one VMexit->VMEntry.  Without CET-SS, we could achieve this fairly
easily with a `call; add $8, %rsp` and `push; ret` pair, but this is not legal
under CET-SS.  In fact, CALL is the only shadow stack "push" operation we
have, and we can't use it a second time if we intend to keep the RAS balanced.

Instead, we keep a real return address on the stack.  This means that for some
of entry.S, %rsp conditionally doesn't reference CPUINFO.

This necessitates swapping the current order of DO_OVERWRITE_RSB and
svm_vmexit_spec_ctrl; while they don't have any specific ordering
requirements, push_one_ras needs to come after svm_vmexit_spec_ctrl or else we
need some very invasive changes to fix up the %rsp changes.

RFC for a couple of reasons.  This does function correctly, but I still want
to do more perf testing.

Secondly, X86_FEATURE_ALWAYS is clearly not ok for committing.  I'm still
debating whether to make this construct available in !CET-SS cases.
Mechanically, its fine, but the safety arguments depend on CET-SS being
active.

In principle, on CPUs which do not suffer Branch Type Confusion, you might be
able to reason a defence-in-depth argument that if an attacker can't control
indirect speculation, then they can't bypass the 1-stuff safety either, but
the only AMD CPUs not vulnerable to BTC have CET-SS anyway.

Third, I'd like some early feedback on how clear it the logic is given the
conditional nature of %rsp not referencing CPUINFO.

Fourth, the alternatives logic (I think) needs improving to not fix up a
direct CALL/JMP displacement if the destination is within the replacement
length.  I did the functional testing before wrapping things in alternatives.

Subject: [PATCH 1/2] x86/svm: Remove regs param from asm-called functions
Date: Thu, 11 Aug 2022 20:59:04 +0100

A optimisation is going to want to conditionally have extra data on the stack
around VMExit.

We could alternative between `mov %rsp, %rdi` and `lea 8(%rsp), %rdi`, but it
is easier just to make the functions void and let the compiler do the (not
very) hard work.

Passing regs is a bit weird for HVM guests anyway, because the resulting
pointer is invariant (this isn't native exception handling where the regs
pointers *are* important), and all functions calculate `current` themselves
which is another invariant.

Finally, the compiler can merge the get_cpu_info() calculation which is common
to both `current` and guest_cpu_user_regs(), meaning the delta in C really is
just one `lea`, and not any more expensive than `mov`'s in ASM anyway.

No functional change.

    "-sdl" is deprecated upstream since 6695e4c0fd9e ("softmmu/vl:
    Deprecate the -sdl and -curses option"), QEMU v6.2, and the option is
    removed by 707d93d4abc6 ("ui: Remove deprecated options "-sdl" and
    "-curses""), in upcoming QEMU v7.1.
    
    Instead, use "-display sdl", available since 1472a95bab1e ("Introduce

    xen/sched: setup dom0 vCPUs affinity only once
    
    Right now, affinity for dom0 vCPUs is setup in two steps. This is a
    problem as, at least in Credit2, unit_insert() sees and uses the
    "intermediate" affinity, and place the vCPUs on CPUs where they cannot
    be run. And this in turn results in boot hangs, if the "dom0_nodes"
    parameter is used.
    
    Fix this by setting up the affinity properly once and for all, in
    sched_init_vcpu() called by create_vcpu().
    
    Note that, unless a soft-affinity is explicitly specified for dom0 (by
    using the relaxed mode of "dom0_nodes") we set it to the default, which
    is all CPUs, instead of computing it basing on hard affinity (if any).
    This is because hard and soft affinity should be considered as
    independent user controlled properties. In fact, if we dor derive dom0's
    soft-affinity from its boot-time hard-affinity, such computed value will
    continue to be used even if later the user changes the hard-affinity.
    And this could result in the vCPUs behaving differently than what the
    user wanted and expects.

As per further down you mean to say it functions correctly without the
use of alternatives. And even then (see below) I suppose it doesn't
function correctly with no (or unused) CET-SS but CONFIG_XEN_SHSTK=y.

I'm afraid it's not entirely clear what you mean here, nor why you've used
X86_FEATURE_ALWAYS in the first place when we have X86_FEATURE_XEN_SHSTK.
If "this construct" is push_one_ras, then the mere use of WRSSQ requires
it to not be used based on a runtime characteristic, not just a build
time one. Hence afaict you could as well put the entire macro body in the
#ifdef that currently encloses only the CET-SS insns.

Yet people may have reasons to turn off its use.

It's assembly code, touching of which needs extra care. Taking together
the size of the entire file (quite small) and the comments you add, I'd
say that's fine.

Yes, unless you want to prefix the CALL with a redundant insn prefix to
hide it from the displacement adjustment logic.

Replace a p2m_is_ram() check in the 2M case by an explicit _PAGE_PRESENT
one, to make more obvious that the subsequent l1e_get_mfn() actually
retrieves something that really is an MFN. It doesn't really matter
whether it's RAM, as the subsequent comparison with the original MFN is
going to lead to zapping of everything except the "same MFN again" case.

Pull common checks out of the switch(). This includes extending a
_PAGE_PRESENT check to L1 as well, which presumably was deemed redundant
with p2m_is_valid() || p2m_is_grant(), but I think we are better off
being explicit in all cases. Note that for L2 (or higher) the grant
check isn't strictly necessary, as grants are only ever single pages.
Leave a respective assertion.

With _PAGE_PRESENT checked uniformly, the suspicious mfn_valid(omfn)
checks can be dropped rather than moved/folded - if anything we'd need
to compare against INVALID_MFN, but that won't come out of l1e_get_mfn().

For L1 replace the moved out condition with a PTE comparison: There's
no need for any update or flushing when the two match.

Signed-off-by: Jan Beulich <jbeulich@suse.com>
---
v3: Compare PTEs, not MFNs. Drop mfn_valid().
v2: Split from previous bigger patch. Add grant related assertion for
    L2.

In preparation for reactivating the presently dead 2M page path of the
function, also deal with the case of replacing an L1 page table all in
one go. Note that the prior comparing of MFNs to bypass the removal of
shadows was insufficient (but kind of benign, for being dead code so
far) - at the very least the R/W bit also needs considering there (to be
on the safe side, compare the full [virtual] PTEs).

While adjusting the first conditional in the loop for the use of the new
local variable "nflags", also drop mfn_valid(): If anything we'd need to
compare against INVALID_MFN, but that won't come out of l1e_get_mfn().

Signed-off-by: Jan Beulich <jbeulich@suse.com>
---
v3: Compare (virtual) PTEs, not MFNs. Correct MFN increment at the
    bottom of the loop. Respect PAT bit.
v2: Split from previous bigger patch.
---
The two mfn_add()s dealing with PAT aren't pretty, but short of us also
having mfn_sub() the cast there is pretty much unavoidable (alternatives
not really looking any neater).

For guests in shadow mode the P2M table gets used only by software. The
only place where it matters whether superpages in the P2M can be dealt
with is sh_unshadow_for_p2m_change(): The table is never made accessible
to hardware for address translation, and the only checks of _PAGE_PSE in
P2M entries in shadow code are in this function (all others are against
guest page table entries). That function has been capable of handling
them even before commit 0ca1669871f8a ("P2M: check whether hap mode is
enabled before using 2mb pages") disabled 2M use in this case for
dubious reasons ("potential errors when hap is disabled").

While doing this, move "order" into more narrow scope and replace the
local variable "d" by a new "hap" one.

Strictly speaking "fn_mask" could also be "unsigned int"; I wasn't sure
whether changing that would cause objections.

While at least sh_unshadow_for_p2m_change() presently relies on this
behavior, it is somewhat odd (and inefficient) for p2m_set_entry() to
split even non-present mappings.

Actually no, I don't think it's safe, and I therefore withdraw the
patch. (I'll re-base the subsequent one accordingly, which you did
give R-b for already.) Whatever content may have been in an L2 table
which is to become a PGT_pae_xen_l2 one may still be in TLBs / paging
structure caches, yet we'll replace those entries without further
flushing.

The opposite direction (previously PGT_pae_xen_l2 trying to become an
ordinary L2) is "fine": Due to the Xen entries still there, its
validation will simply fail.

show_hvm_stack() requires interrupts to be enabled to avoid triggering
the consistency check in check_lock() for the p2m lock. Add a respective
check. To avoid this check triggering when coming through
spurious_interrupt() requires adding reentrancy protection / handling
there alongside transiently (re-)enabling IRQs.

This is not very different from an application that was built against an 
old Xenstored and would not be capable to talk properly with the new 
Xenstored if the feature is enabled. I understand that...

... when using xenstore-stubdom xenstored it means that the feature will 
have to be disable for all dom0 connections.

However, it seems unlikely to me that someone will switch to a 
xenstore-stubdom on a whim because there are also scalability concerns 
(one ring to rule all connections). So I think it would be fair to say 
that your application may need to be tweak if you are not using the same 
feature as the system.

This is not that simple. Your assumption is the feature will not change 
the behavior exposed to the application.

I don't think we have such feature today but I don't see what prevents 
us to do that.

Given the question below, I guess you mean per-domain quotas that are 
not the default ones. If yes, then they should be split.

I don't have a strong opinion on this.

I don't have a strong opinion.

The involved asm() expands to large enough a construct that often the
compiler would decide against inlining when a containing function is
used more than once in a CU. Use the "inline" keyword when supported by
the compiler in conjunction with asm().

The INIT_SECTIONS_ONLY dependency is because in that case "inline" gets
expanded to "__inline__ __init", which obviously can't be used with
asm(). But for init-time only code we're also less worried ...

v2: Re-base.

Perhaps this wants extending to other asm()-s involving ALTERNATIVE().
At which point the question is whether instead of altcall_asm we'd want
to have something like asm_inline.

I understand that Linux uses Kconfig for the feature detection. The
discussion on whether we want to generally follow this model continues
to be pending / stalled. In this particular case the error output from
the compiler when "inline" is not supported can be huge (thousands of
lines, partly because of the many nested levels of macro expansions),
making it close to impossible to recognize what the actual issue is. Yet
that's what would be happening if one switched the compiler from one
supporting the feature to one not supporting it, without remembering to
explicitly have xen/.config re-generated.

NIT: I would write arm_smmu_write_s2cr() so it is consistent with the 
line above.

Meanwhile, I was reading up on virtio-snd and found some patches in the int=
ernet. However, those patches are not
present in the qemu source code (https://gitlab.com/qemu-project/qemu.git).=
 Do you know

  1.  If virtio-snd front end driver is another option to enable audio in H=
VM guest with Qemu/ALSA as backend in dom0?
  2.  If yes, how is it different from xen front end drivers?

Also, regarding enabling Xen PV audio front end device drivers, you have me=
ntioned that I need to enable backend using libxenbe and snd_be. Does it me=
an, in this case, Qemu is not involved in the audio backend? Any pointers t=
o understand this overall architecture (Xen PV audio front end driver/snd_b=
e/qemu/ALSA) will be extremely helpful.

Regards,
Jyotirmoy

I understand that "users" doesn't imply guests. Hovewer, it is still not

Anyway, I think it would be good to document such behaviors because they 
don't seem to be obvious.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

  commit 66dd1c62b2a3c707bd5c55750d10a8223fbd577f
  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

Just spotted that libxenbe and snd_be were mentioned ...

    ... I am not familiar with sound internals, but have an overall 
understanding about Xen PV audio.


1. The backend (snd_be) is Xen PV backend, not a virtio. It is a 
standalone user-space application, so Qemu is not involved here if we 
are speaking about snd_be+libxenbe. The backend can work on top of Pulse 
or Alsa and supports playback and record.
    https://github.com/xen-troops/snd_be/commits/master
    Some details you can find at:
    https://github.com/xen-troops/snd_be/blob/master/README.md

2. The library (libxenbe) contains various Xen specific stuff, such as 
event channel, xenstore, grant table, etc needed for Xen PV backend to 
work, so it should be linked by snd_be.
    https://github.com/xen-troops/libxenbe/commits/master
    Both snd_be and libxenbe are written on C++, both are part of Yocto 
build, but I guess they can be built standalone.


3. The frontend is in upstream Linux and supported, the protocol is also 
there, toolstack also supports PV audio configuration (no extra patches 
are needed):
    https://elixir.bootlin.com/linux/v5.19.1/source/sound/xen
https://elixir.bootlin.com/linux/v5.19.1/source/include/xen/interface/io/sndif.h

    Also the guest should be built with CONFIG_SND_XEN_FRONTEND=y

Subject: [PATCH v2 2/3] x86/build: Don't convert boot/{cmdline,head}.bin back to .S

There's no point wasting time converting binaries back to asm source.  Just
use .incbin directly.  Explain in head.S what these binaries are.

Also, explicitly align the blobs.  They contain 4-byte objects, and happen to
be 4-byte aligned currently because of the position of `lret` and the size of
cmdline.S but this is incredibly fragile.

No functional change.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

That would be fine if you know that your client can support it. Reading 
the rest of the e-mail, AFAIU your aim is to use SET_FEATURES to 
indicate which features is supported by Xenstored. This may or may not 
be supported by the client.

When I replied, I had a different idea in mind for SET_FEATURES. But I 
think it wouldn't work in a generic setup because an handshake would be 
necessary (the client would need to advertise the features it supports).

Anyway, now I understand your point and agree with you the we want to 
only have the field 'features' for ring connection.

Thanks for the clarification!

Cheers,

 * Always emit current.  It's critically important.
 * Do not render (0000000000000000) for the symbol in guest context.  It's
   just line-noise.  Instead, explicitly identify which Xen vs guest context.
 * Try to tabulate the data, because there is often lots of it.

Hi all,

This is another collection of patches that I accumulated while
reworking the boot code. I am not planning to target Xen 4.17
for the boot code (still working on it and it is risky). But I
the clean-ups and improvement patches could be.

Cheers,

From: Julien Grall <jgrall@amazon.com>

There are a few places in the code that need to find the slot at a
given page-table level.

So create a new macro get_table_slot() for that. This will reduce
the effort to figure out whether the code is doing the right thing.

The new macro is using 'ubfx' (or 'lsr' for the first level) rather
than the existing sequence (mov_w, lsr, and) because it doesn't require
a scratch register and reduce the number of instructions (4 -> 1).

Subject: [PATCH 1/7] xen/arm64: head: Don't set x22 and update the documentation
Date: Fri, 12 Aug 2022 20:24:40 +0100

From: Julien Grall <jgrall@amazon.com>

Since commit 7e14a47e7c73 ("xen/arm64: head Rework and document
launch()"), the boot code is setting x22 but not read it.

So remove the two instructions setting x22 and update the documentation
to show x22 has no specific purpose.

Subject: [PATCH 2/7] xen/arm64: head: Introduce get_table_slot() and use it
Date: Fri, 12 Aug 2022 20:24:41 +0100

From: Julien Grall <jgrall@amazon.com>

There are a few places in the code that need to find the slot
at a given page-table level.

So create a new macro get_table_slot() for that. This will reduce
the effort to figure out whether the code is doing the right thing.

Take the opportunity to use 'ubfx'. The only benefits is reducing
the number of instructions from 2 to 1.

The new macro is used everywhere we need to compute the slot. This
requires to tweak the parameter of create_table_entry() to pass
a level rather than shift.

Note, for slot 0 the code is currently skipping the masking part. While
this is fine, it is safer to mask it as technically slot 0 only covers
bit 48 - 39 bit (assuming 4KB page granularity).

Take the opportunity to correct the comment when finding the second
slot for the identity mapping (we are computing the second slot
rather than first).

Signed-off-by: Julien Grall <jgrall@amazon.com>

    This patch also has the benefits to reduce the number
    of use of {ZEROETH, FIRST, SECOND, THIRD}_SHIFT. The next
    patch for arm32 will reduce further.

Subject: [PATCH 4/7] xen/arm32: heap: Rework adr_l so it doesn't rely on where Xen is loaded
Date: Fri, 12 Aug 2022 20:24:43 +0100

From: Julien Grall <jgrall@amazon.com>

At the moment, the macro addr_l needs to know whether the caller
is running with the MMU on. This is fine today because there are
only two possible cases:
 1) MMU off
 2) MMU on and linked to the virtual address

This is still cumbersome to use for the developer as they need
to know if the MMU is on.

Thankfully, Linux developpers came up with a great way to allow
adr_l to work within the range +/- 4GB of PC by emitting a PC-relative
reference [1].

Re-use the same approach on Arm and drop the parameter 'mmu'.

    I haven't added an Origin tag because this is quite different
    from the Linux commit. I am happy to add one if this is desired..

From: Julien Grall <jgrall@amazon.com>

At the moment, the strings are in text right after each use because
the instruction 'adr' has specific requirement on the location
and the compiler will forbid cross section label.

The macro 'adr_l' was recently reworked so the caller doesn't need
to know whether the MMU is on. This makes it easier to use where
instructions can be run in both context.

This also means that the strings don't need to be part of .text
anymore. So move them to .rodata.str.

Currently the output is looking like:

(XEN) 1ST[0x1] = 0x000000004015ff7f
(XEN) 2ND[0x1f] = 0x00500000bfe00f7d

The content of the entries are not aligned making a bit trickier to
read (I appreciate this is a matter of taste).

Align the values by forcing the index to be always printed using
3 characters (enough to cover 512 in hexadecimal).

New output:

(XEN) 1ST[0x001] = 0x000000004015ff7f
(XEN) 2ND[0x01f] = 0x00500000bfe00f7d

page table walk) for hypervisor data abort.

For data abort, the HSR will be set properly and so replace the call
to do_unexpected_trap() with do_trap_hyp_sync() to dispatch the error.

Subject: [PATCH] add SPDX to arch/arm/*.c
Message-ID: <alpine.DEB.2.22.394.2208121758520.3790@ubuntu-linux-20-04-desktop>
User-Agent: Alpine 2.22 (DEB 394 2020-01-19)

Content-Type: text/plain; charset=US-ASCII

Add SPDX license information to all the *.c files under arch/arm.

Subject: [PATCH v4 02/11] drivers/char: reset XHCI ports when initializing dbc
Date: Sat, 13 Aug 2022 03:38:52 +0200
Message-Id: <f9b47a78968e06f5af2930d99e5dc558fdc131f2.1660354597.git-series.marmarek@invisiblethingslab.com>
X-Mailer: git-send-email 2.35.3
In-Reply-To: <cover.05bda81c2f5ff91948f96e397b6836bcede71ef8.1660354597.git-series.marmarek@invisiblethingslab.com>
References: <cover.05bda81c2f5ff91948f96e397b6836bcede71ef8.1660354597.git-series.marmarek@invisiblethingslab.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reset ports, to force host system to re-enumerate devices. Otheriwse it
will require the cable to be re-plugged, or will wait in the
"configuring" state indefinitely.

Trick and code copied from Linux:
drivers/usb/early/xhci-dbc.c:xdbc_start()->xdbc_reset_debug_port()

Signed-off-by: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com>
Acked-by: Jan Beulich <jbeulich@suse.com>
---
Changes in v3:
- adjust for renamed driver
- use readl() etc for MMIO
- simplify xcap lookup
- drop acked-by
Changes in v2:
- use uint32_t instead of u32
- code style

Message-Id: <cover.05bda81c2f5ff91948f96e397b6836bcede71ef8.1660354597.git-series.marmarek@invisiblethingslab.com>

This is integration of https://github.com/connojd/xue into mainline Xen.
This patch series includes several patches that I made in the process, some are
very loosely related.

The driver developed by Connor supports console via USB3 debug capability. The
capability is designed to operate mostly independently of normal XHCI driver,
so this patch series allows dom0 to drive standard USB3 controller part, while
Xen uses DbC for console output.

Changes since RFC:
 - move the driver to xue.c, remove non-Xen parts, remove now unneeded abstraction
 - adjust for Xen code style
 - build for x86 only
 - drop patch hidding the device from dom0
Changes since v1:
 - drop ehci patch - already applied
 - adjust for review comments from Jan (see changelogs in individual patches)
Changes since v2:
 - add runtime option to share (or not) the controller with dom0 or other domains
 - add RX support
 - several smaller changes according to review comments
Changes since v3:
 - put controller sharing behind experimental kconfig option
 - several other changes according to review comments

Subject: [PATCH v4 06/11] IOMMU: add common API for device reserved memory
Date: Sat, 13 Aug 2022 03:38:56 +0200

Add API similar to rmrr= and ivmd= arguments, but in a common code. This
will allow drivers to register reserved memory regardless of the IOMMU
vendor.
The direct reason for this API is xhci-dbc console driver (aka xue),
that needs to use DMA. But future change may unify command line
arguments for user-supplied reserved memory, and it may be useful for
other drivers in the future too.

This commit just introduces an API, subsequent patches will plug it in
appropriate places. The reserved memory ranges needs to be saved
locally, because at the point when they are collected, Xen doesn't know
yet which IOMMU driver will be used.

Changes in v4:
- mark functions as __init
- use pci_sbdf_t type
Changes in v3:
 - adjust code style

Handle parameters similar to dbgp=ehci.

Implement this by not resettting dbc->sbdf again in dbc_init_xhc(), but
using a value found there if non-zero. Additionally, add xue->xhc_num to
select n-th controller.

Changes in v4:
 - adjust error message
Changes in v3:
 - adjust for xhci-dbc rename
 - drop redundant check in parsing dbgp= option
Changes in v2:
 - unsigned int xhc_num
 - code style

Subject: [PATCH v4 05/11] console: support multiple serial console simultaneously
Date: Sat, 13 Aug 2022 03:38:55 +0200
Message-Id: <e750ea9b05c1976a0439277a74ee2b439714a6c1.1660354597.git-series.marmarek@invisiblethingslab.com>

Previously only one serial console was supported at the same time. Using
console=com1,dbgp,vga silently ignored all but last serial console (in
this case: only dbgp and vga were active).

Fix this by storing not a single sercon_handle, but an array of them, up
to MAX_SERCONS entries. The value of MAX_SERCONS can be chosen in
kconfig, the default (4) is arbitrary, inspired by the number of
SERHND_IDX values.

Make console_steal() aware of multiple consoles too. It can now either
steal output from specific console (for gdbstub), or from all of them at
once (for console suspend).

Changes in v4:
- use unsigned int for loop counters
- other minor changes
Changes in v3:
- adjust console_steal() for multiple consoles too
- add MAX_SERCONS to kconfig
- add warning about sync_console impact
- add warning if too many consoles are configured
- log issue with PCI spec parsing

[Connor]
Xue is a cross-platform USB 3 debugger that drives the Debug
Capability (DbC) of xHCI-compliant host controllers. This patch
implements the operations needed for xue to initialize the host
controller's DbC and communicate with it. It also implements a struct
uart_driver that uses xue as a backend. Note that only target -> host
communication is supported for now. To use Xue as a console, add
'console=dbgp dbgp=xhci' to the command line.

[Marek]
The Xue driver is taken from https://github.com/connojd/xue and heavily
refactored to fit into Xen code base. Major changes include:
- rename to xhci_dbc
- drop support for non-Xen systems
- drop xue_ops abstraction
- use Xen's native helper functions for PCI access
- move all the code to xue.c, drop "inline"
- build for x86 only
- annotate functions with cf_check
- adjust for Xen's code style

At this stage, only the first xHCI is considered, and only output is
supported. Later patches add support for choosing specific device, and
input handling.
The driver is initiallized before memory allocator works, so all the
transfer buffers (about 230KiB of them) are allocated statically and will
use memory even if XUE console is not selected. The driver can be
disabled build time to reclaim this memory.
Most of this memory is shared with the controller via DMA. Later patch
will adjust structures placement to avoid anything else to be placed on
those DMA-reachable pages. This also means str_buf cannot use static
initializer, without reserving (at least) a whole page page in .data (or
more, when combined with other structures).

Changes in v4:
- adjust alignments
- check if BAR0 is initialized by the firmware
- some more type fixes
- use #define for doorbell mask
- remove chunk belonging to later patch
- explain in commit message why no static initializer for str_buf
Changes in v3:
- rename to xhci-dbc
- add empty stub for xhci_dbc_uart_init(), to avoid #ifdef in setup.c
- use PCI_BASE_ADDRESS_MEM_MASK
- make strings init more readable
- avoid infinite extended caps lookup
- size the whole 64bit BAR
- rename CONFIG_HAS_XHCI to CONFIG_XHCI
- use cpu_relax(), drop xue_sys_pause()
- disable memory decoding for the BAR sizing time, and enable it
  explicitly
- drop mmio_size field - it's used only in init_xhc() function
  internally
- use readl()/writel() for accessing MMIO
- add pci_ro_device(), to protect device before later patch(es) add
  other protections
- fix setting dequeue pointer based on events: TRB ring was page
  aligned, not 16-page aligned, so just taking DBC_TRB_RING_MASK bits
  doesn't work; instead, calculate distance from the ring beginning;
  while at it, fix off by one error there; dequeue pointer isn't used
  much yet, but it will be useful for RX handling
- split dbc_ensure_running() out of dbc_flush() - it make dbc_flush()
  more logical, and will make even more sense with RX support added
- make enum names upper case

Changes in v2:
- drop #pragma pack
- fix indentation in Kconfig
- minor style fixes
- use cache_flush()
- mark init functions as __init, and return bool
- fix PCI_SBDF usage, use constants from pci_regs.h
- add command line docs
- allow disabling the driver in menuconfig, to reclaim 2MB allocated
  memory
- guard unused debug functions with #ifdef XUE_DEBUG

+ * TRB ring (summarized from the manual):
+ *
+ * TRB rings are circular queues of TRBs shared between the xHC and the driver.
+ * Each ring has one producer and one consumer. The DbC has one event
+ * ring and two transfer rings; one IN and one OUT.
+ *
+ * The DbC hardware is the producer on the event ring, and
+ * dbc driver is the consumer. This means that event TRBs are read-only from
+ * the dbc driver.
+ *
+ * OTOH, dbc drive is the producer of transfer TRBs on the two transfer
+ * rings, so dbc driver enqueues transfers, and the hardware dequeues
+ * them. The dequeue pointer of a transfer ring is read by
+ * dbc driver by examining the latest transfer event TRB on the event ring. The
+ * transfer event TRB contains the address of the transfer TRB that generated
+ * the event.
+ *
+ * To make each transfer ring circular, the last TRB must be a link TRB, which
+ * points to the beginning of the next queue. Note that this implementation
+ * does not support multiple segments, so each link TRB points back to the
+ * beginning of its own segment.

Subject: [PATCH v4 09/11] drivers/char: mark DMA buffers as reserved for the XHCI
Date: Sat, 13 Aug 2022 03:38:59 +0200
Message-Id: <b3d917bd1d46393857bd82bcdef9d4486d8f3945.1660354597.git-series.marmarek@invisiblethingslab.com>

The important part is to include those buffers in IOMMU page table
relevant for the USB controller. Otherwise, DbC will stop working as
soon as IOMMU is enabled, regardless of to which domain device assigned
(be it xen or dom0).
If the device is passed through to dom0 or other domain (see later
patches), that domain will effectively have access to those buffers too.
It does give such domain yet another way to DoS the system (as is the
case when having PCI device assigned already), but also possibly steal
the console ring content. Thus, such domain should be a trusted one.
In any case, prevent anything else being placed on those pages by adding
artificial padding.

Changes in v3:
- adjust for xhci-dbc rename
- do not raise MAX_USER_RMRR_PAGES
- adjust alignment of DMA buffers

Add another work ring buffer for received data, and point IN TRB at it.
Ensure there is always at least one pending IN TRB, so the controller
has a way to send incoming data to the driver.
Note that both "success" and "short packet" completion codes are okay -
in fact it will be "short packet" most of the time, as the TRB length is
about maximum size, not required size.

Subject: [PATCH v4 11/11] drivers/char: allow driving the rest of XHCI by a domain while Xen uses DbC

That's possible, because the capability was designed specifically to
allow separate driver handle it, in parallel to unmodified xhci driver
(separate set of registers, pretending the port is "disconnected" for
the main xhci driver etc). It works with Linux dom0, although requires
an awful hack - re-enabling bus mastering behind dom0's backs.
Linux driver does similar thing - see
drivers/usb/early/xhci-dbc.c:xdbc_handle_events().

When controller sharing is enabled in kconfig (option marked as
experimental), dom0 is allowed to use the controller even if Xen uses it
for debug console. Additionally, option `dbgp=xhci,share=` is available
to either prevent even dom0 from using it (`no` value), or allow any
domain using it (`any` value).

In any case, to avoid Linux messing with the DbC, mark this MMIO area as
read-only. This might cause issues for Linux's driver (if it tries to
write something on the same page - like anoter xcap), but makes Xen's
use safe. In practice, as of Linux 5.18, it seems to work without
issues.

Signed-off-by: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com>

Changes in v4:
- minor fix for cmdline parsing
- make sharing opt-in build time, with option marked as EXPERIMENTAL
- change cmdline syntax to share=<bool>|hwdom
- make share=hwdom default (if enabled build-time)
Changes in v3:
- adjust for xhci-dbc rename
- adjust for dbc_ensure_running() split
- wrap long lines
- add runtime option for sharing USB controller

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

Thanks for doing it. This will make easier to understand the license in 
each file. There are a couple of places below where the SDPX tag is 
incorrect. How did you figure out the which license to use?

Also, I think we should consider to add a section about SPDX in our 
coding style so new files are using it. So we don't end up with a mix in 
arch/arm/*.

Technically, this is a comment. So this should be /* ... */ to follow 
Xen coding style. Also...

... this comment contains information about the license. As you add the 
SPDX, the "long" version should be removed. This would also make easier 
to verify the SPDX you add match existing license.

This file had no explicit license. I had a look at the 'git log' and 
AFAICT this was either new code and came from Linux. So this looks fine 
to add GPLv2 here.

This tag doesn't match the license below. It is currently GPLv2+. I 
don't think you can change it without consulting the author. But if it 
is, then it should be mentioned in the commit message.

I remember we discussed in the past that some files were GPLv2+. But I 
can't remember what was the outcome (I can't find the thread). IIRC 
GPLv2+ is a lot more restrictive than GPLv2 and could prevent some 
companies to contribute.

Same here about GPLv2+. Please go through the rest of the files to 
confirm the license.

Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-amd64-libvirt           6 libvirt-build            fail REGR. vs. 172123
 build-i386-libvirt            6 libvirt-build            fail REGR. vs. 172123

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

Hi Thorsten,

This appears stalled again and we are now over three months
from the first report of the regression, The only excuse for
ignoring your comments, and other comments on the patches
in this patch series for this long a time is that the patch series
for some reason cannot be considered a true regression. If this is a
regression, then, IMHO, this needs to have a higher priority by the
maintainers, or the maintainers need to explain why this regression
cannot be fixed in a more timely manner. But continued silence
by the maintainers is unacceptable, IMHO. This is especially true
in this case when multiple fixes for the regression have been
identified and the maintainers have not yet clearly explained why
at least a fix, even if temporary, cannot be applied immediately
while we wait for a more comprehensive fix.

At the very least, I would expect Juergen to reply here and say that
he is delayed but does plan to spin up an updated version and include
the necessary links in the new version to facilitate your tracking of
the regression. Why the silence from Juergen here?

Best regards,

Chuck

Hi Thorsten,

IMHO, silence here is unacceptable given that this is supposed to
be fixing a regression and not just adding a new feature or
re-working the code in a case where there is no regression.

The regression was first reported on May 4, 2022, now over
three months ago:

https://lore.kernel.org/regressions/YnHK1Z3o99eMXsVK@mail-itl/

Why has Juergen not at least responded in some way to the
comments that Boris has made here? Why has Boris not
pinged Juergen by now, which is almost four weeks after his
comment and over three months from the first report of the
regression? IMHO, both Juergen and Boris are not treating
this with the priority of a regression fix. At the very least,
they should reaffirm their commitment to fix the regression
in a timely manner or explain what factors demand that the
Linus regression rule be set aside in this case.

There are valid reasons to delay a fix, but in all the discussion
of the various patches that have been proposed to fix this
regression, no maintainer has yet given a clear and reasonable
explanation for why this is not getting a higher priority from the
developers.

Some developers, (Dave, Luto, and Peter) have ignored a fix
proposed by Jan Beulich as you pointed out in an earlier message
to Jan Beulich here:

https://lore.kernel.org/lkml/4c8c9d4c-1c6b-8e9f-fa47-918a64898a28@leemhuis.info/

To his credit, Jan Beulich replied to your message in a reasonable
manner but he also could not explain why Dave, Luto, and Peter
ignored Jan's patch and remain silent in the discussion of the possible
fixes for this regression. I note also that the original report of the
regression identified a specific commit that also fixes the regression
if that bad commit is reverted, and that commit is also mentioned in
the aforementioned message to Jan about his proposed fix. It is a commit
that lives in the i915 Intel GPU/DRM driver, commit bdd8b6c98239, and
my testing confirms the regression can also be fixed by reverting
bdd8b6c98239 instead of applying Jan Beulich's patch that was the
subject of the aforementioned message from you to Jan Beulich where
you also expressed your dissatisfaction with the silence of some
developers (Dave, Lotu, and Peter) when there is a regression that needs
fixing.

Why their silence? In that same message, you pondered that it might
be necessary to bring this matter to Linus' attention. The developers'
silence makes me think this regression is a regression the developers
do not want to fix. And that would be a clear violation of the Linux
regression rule if it were true. So, Thorsten, I think it is time for you to
elevate this to Linus if the developers do not clearly explain why they
are ignoring this again.

Best regards,

Chuck

How about: it is summer here and people usually take their vacations
during that time and everything takes a bit longer than usual?

Hello Boris,

I am grateful that you took the time to respond and say it will be fixed soon.
By soon, I presume that means within two weeks as the guidance for
fixing regressions recommends:

https://www.kernel.org/doc/html/latest/process/handling-regressions.html

Quoting from that page: "Try to fix regressions quickly once the culprit has
been identified; fixes for most regressions should be merged within two
weeks, but some need to be resolved within two or three days."

If the regression is not fixed by the end of August, I don't think it would
be "nonsense" for me to send another PING at that time. I also think the
PING I sent earlier today is not "nonsense," given that this regression has been
waiting for a fix for over three months, which is much longer than the
expected time to fix a regression of two weeks.

Best regards,

Chuck

This is a fairly long message but I think what I need to say
here is important for the future success of Linux and open
source software, so here goes....

Update: I accept Boris Petkov's response to me yesterday as reasonable
and acceptable if within two weeks he at least explains on the public
mailing lists how he and Juergen have privately agreed to fix this regression
"soon" if he does not actually fix the regression by then with a commit,
patch set, or merge. The two-week time frame is from here:

https://www.kernel.org/doc/html/latest/process/handling-regressions.html

where developers and maintainers are exhorted as follows: "Try to fix
regressions quickly once the culprit has been identified; fixes for most
regressions should be merged within two weeks, but some need to be
resolved within two or three days."

I also think there is a private agreement between Juergen and Boris to
fix this regression because AFAICT there is no evidence in the public
mailing lists that such an agreement has been reached, yet Boris yesterday
told me on the public mailing lists in this thread to be "patient" and that
"we will fix this soon." Unless I am missing something, and I hope I am,
the only way that a fix could be coming "soon" would be to presume
that Juergen and Boris have agreed to a fix for the regression in private.

However, AFAICT, keeping their solution private would be a violation of
netiquette as described here:

https://people.kernel.org/tglx/notes-about-netiquette

where a whole section is devoted to the importance of keeping the
discussion of changes to the kernel in public, with private discussions
being a violation of the netiquette that governs the discussions that
take place between persons interested in the Linux kernel project and
other open source projects.

Yet, in one of his messages to me yesterday, Boris appended the link
to the netiquette rules, thus implicitly accusing me of violating the
netiquette rules when in fact he is the one who at least seems to be
violating the rule forbidding private discussions of changes to the
kernel once a patch set is already up for discussion on the public
mailing lists.

Of course Boris can exonerate himself completely if within two
weeks he at least explains on the public mailing lists how he and
Juergen have agreed to fix the regression. I sincerely hope he at
least does that within the next two weeks, or even better, that he
exonerates himself by actually committing the official fix for the
regression within the next two weeks.

However, I will only believe it when I see it. When it comes to the
Linux kernel, I go by what I see  in the performance of the Linux
kernel in my computing environments, what I see on the public
mailing lists and in the official documentation, and by what I
see in the source code itself. I do not go by blind faith in any
single developer. I am not religious when it comes to the Linux
kernel. Instead, I am scientific and practical about it.

Finally, please forgive me also if I am mistaken in my assumption
that these rules of netiquette apply no less to the developers and
maintainers of the Linux kernel than to others who wish to offer
their contributions to the development of the Linux kernel. If the
rules of netiquette do not apply to the developers and maintainers,
of the kernel, then, IMHO, the great advantage of open source
software development is totally lost, because the advantage of the
open source software development model depends at least as
much on free and open access to the discussions about the
source code conducted by the developers and maintainers as it
does on the freedom to have access to the source code itself.
If someone here tells me that those rules of netiquette need
not be followed by the developers and maintainers I certainly
hope someone else will come to the defense of those same
wise rules that have allowed such a successful open source
software ecosystem to flourish and thrive around this project,
the Linux kernel.

IMHO, the day someone make the decision to stop enforcing these
wise rules is the day that the open source development model will
begin to lose its advantage over proprietary software development
models. And perhaps the most important rule of all for the continued
success of Linux and open source software development is the Linus
regression rule, with the rule that discussions about changes
to the source code must be done in public being a close second in
importance to the Linus regression rule.

Best Regards,

Chuck

Subject: [GIT PULL] xen: 2nd round of patches for 6.0-rc1
Date: Sun, 14 Aug 2022 11:07:37 +0200

Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-6.0-rc1b-tag

xen: 2nd round of patches for 6.0-rc1

It contains the following patches:

- a series for fixing the handling of the "persistent grants" feature
  negotiation between Xen blkfront and Xen blkback drivers

- a cleanup of xen.config and adding xen.config to Xen section in
  MAINTAINERS

- a patch for supporting HVMOP_set_evtchn_upcall_vector, which is more
  compliant to "normal" interrupt handling than the global callback used
  up to now

- 2 further small cleanups

Thanks.

Juergen

Hi Thorsten,

Well, that did not take long. Juergen responded with a message,
which is encrypted and not delivered to my mailbox because I do not
have the PGP keys, presumably to make it difficult for me to continue
the discussion and defend myself after I was accused of violating
the netiquette rules yesterday by Boris:

https://lore.kernel.org/lkml/c88ea08c-a9d5-ef6a-333a-db9e00c6da6f@suse.com/raw

Fortunately, lore.kernel.org did decrypt Juergen's message so you can read
what he wrote in response to my message there. I don't think what Juergen said
there is very constructive although I am not surprised he seeks to defend himself,
and he makes many valid points that are good for developers and Linux insiders
but not so good for users and the long-term success of the Linux kernel project,
so I am not going to reproduce what he said in this message, but I think you
need to read it to help you understand why this regression is not being fixed
in a timely manner:

https://lore.kernel.org/lkml/c88ea08c-a9d5-ef6a-333a-db9e00c6da6f@suse.com/

Sorry for the trouble, but I am just a user trying to understand why this
regression has not been fixed for over three months.  If this is the best the
Linux kernel community can do in response to my questions about this regression,
then in the long run, I can assure, you, the open source development model is
doomed to a slow, long, and eventually painful death.

Best regards,

Chuck

It's not that my e-mail client could not read it, there is no evidence it
was ever sent to me. I use aol.com which is administered by Yahoo!. It
did not even appear in the web interface for my e-mail service, so it
was never delivered to my e-mail client, which is Thunderbird. Neither
the Windows nor the Linux client can retrieve a message not delivered
to the Yahoo! servers! I also checked the Junk and Spam folders and it
was not there either. But I received your message and other messages
normally. It is as if the message was sent to everyone else on the To:
and Cc: lists except for me. I think the problem was on the sender's end
or with my e-mail service, Yahoo!, which apparently does not accept signed
messages without some special configuration that I have not done
with Yahoo! yet. I will look into it next week.

The To: line had your address in it, so it was sent to you, and again,
it was not encrypted as you claimed, but rather just signed to verify he
was the sender.  That's not making anything difficult for anyone, so I
think you owe him an apology here, especially as you are asking him to
do work for you.

best of luck!

Dear Greg,

Thanks for the advice. I appreciate it. Below follows my apology to Juergen and
and Thorsten and some additional comments for anyone willing to hear what
I am trying to say as I continue to try to participate in the discussion of this
regression...

Dear Juergen and Thorsten,

I do apologize since I agree there is not enough evidence to conclude that
Juergen purposely made it difficult for me to respond to and defend myself
against the negative things he said about me in the e-mail I never received
from him.

I am not going to try to defend myself either, since it is not necessary and is
probably an impossible task for me to succeed in defending myself here in
this forum. The e-mail you tried and failed to send to me is currently
publicly available on more than one public mailing lists and it speaks for
itself. Each person who reads it and the other relevant messages in the
thread will decide for himself or herself what that message means.

So far I am inclined to think most people who will even take the time to
read the thread will judge me to be in the wrong, and I also am inclined
to think many who are Cc'd on this thread are already ignoring me
because they consider me to be a total jerk. That's fine, but that's just
their opinion, especially if they base their opinion only on a custom
of hazing users who dare to say what they think on the Linux public
mailing lists.

But since you are the persons who create the Linux kernel, I will express
my opinion that your decision to reject my efforts to help the kernel
developers and maintainers work better together with each other and
with users like me who are brave enough to say what they think on these
public mailing lists is the wrong decision if your goal is really to make
Linux and open source software development able to continue to produce
high quality software that is actually useful to people.

I say that because I am trying to scream to you as loud as I can: "Linux
software is no longer useful to me." No one here seems willing to hear
that message. I wonder if Linus even cares about that anymore. And that is
sad, because Linux was a great project. Unfortunately, now, it is clear to
me it is going to die a slow, painful death. The Linux kernel is a big and
powerful enough project to survive for quite a while, and I probably won't
live to see its death, but unless the people who define the Linux kernel
community change, it will eventually die.

Best regards and good luck to all of you,

Chuck

You misunderstand me completely. I am not here to ask Juergen to do any
work for me, he is the one who volunteered to fix a regression that affects
my computer, so I am interested in what he has to say, and I am on this mailing
list to find out if he, and other Linux developers and maintainers, are the kind
of people I want to have writing the software that runs on my computers.
I don't have to tell you what my decision about that is, but do you really think
I want people who refuse to answer my questions about the software they
are writing for my computers to continue to be the ones I rely on for the
security and stability of my computer systems? If you think I am that stupid,
I suppose you also think I am too stupid to receive an e-mail message that
Juergen tried to send me earlier today. The fact is, Juergen is the only
person I am aware of who has tried and failed to get an e-mail message
delivered to me during the past thirty years since I started using e-mail.
That's quite an accomplishment for Juergen to achieve!

Best regards,

Chuck

You are busy, and that is always true for someone with your responsibilities.
That is an acceptable reason to delay your responses for a time.

I have asked for this on more than one occasion, but I was either
ignored or shot down every time. The fact is, among the persons
who have the power to actually commit a fix, only you and Boris
are currently indicating any willingness to actually fix the regression.
I will say the greater responsibility for this falls on Boris because
he is an x86 maintainer, and you have every right to walk away
and say "I will not work on a fix," and I would not blame you or accuse
you of doing anything wrong if you did that. You are under no obligation
to fix this. Boris is the one who must fix it, or the Intel developers,
by reverting the commit that was originally identified as the bad
commit.

If it is any consolation to you, Juergen, I think the greatest problem
is the silence of the drm/i915 maintainers, and Thorsten also expressed
some dissatisfaction because of that, but since there is also some
consensus that the fix should be done in x86 or x86/pat instead of
in drm/i915, another problem is the lack of initiative by the x86
developers to fix it. If they do not know how to fix it and need to
rely on someone with Xen expertise, they should be giving you
more assistance and feedback than they currently are. So far, only
Boris shows any interest, and now my only critique of your behavior
is that in your message, you chose to engage in an ad hominum attack
against me instead of taking the same amount of time to at least
briefly answer the questions Boris raised about your patch set over
three weeks ago. Your decision to attack me instead of working on
the fix was, IMHO, not helpful and constructive.
> Accusing me and Boris is not acceptable at all!

OK, I understand, now we are even. I have said it is unacceptable to
not give greater priority to the regression fix or at least keep interested
persons informed if there is a reason to continue to delay a fix, which
ordinarily should only take two weeks, but now we are at more than
three months. Now, you are saying it is unacceptable for me to accuse
you and Boris. OK, so we are even. We each think the other is acting
in an unacceptable way. I still think it is unacceptable to not work on
the fix and instead engage in ad hominum attacks. Maybe I am wrong.
Maybe maintainers are supposed to attack persons who are not
maintainers when such outsiders try to help and encourage better
cooperation and end the hostile silence by the maintainers who are
responsible to fix this. But that does not make sense to me. It makes
sense to hold accountable those persons who are responsible for fixing
this (and you, Juergen, are not the one that needs to be held accountable).
AFAICT, that is not being done and instead I am being attacked for trying
to get work towards a fix rolling again.

I am just asking for some transparency and an indication that
a fix is really and truly in sight. It would only take you a few
minutes to fulfill what I am asking you to do now. The fact is,
Boris commented on your patches over three weeks ago and
asked you if you accepted the approach he outlined and you
have remained silent. That does not indicate you and Boris
are close to coming to a fix even though Boris stated that a fix
is coming soon. Based on what has been said on the mailing
lists, I just don't see the fix coming soon. That's all I can say
about it now.

That is certainly a valid reason to delay work on this - you were on
vacation. I hope you enjoyed yourself and had a good time. But I
had no way of knowing this because I was not part of the IRC
communication, so I cannot be blamed for not knowing this.

> I will continue with the patches as soon as I find time to do so.

I am willing to wait patiently for you to get back to these patches,
and I hope you can agree that you should find a few minutes
to confirm or deny Boris' statement that a fix is coming "soon"
by posting a public message to this thread within the next two
weeks, given that this regression has not been fixed for over three
months. I will not be upset if you say something like: "it looks like
it might take a while for Boris and I to work out the details of a fix,
it might take until the end of the year," and briefly explain why there
will be a delay. Boris might not like that because it would contradict
his statement that a fix is coming "soon" but I would rather be told
the truth - that the fix is going to be delayed, than be told a lie - that
a fix is coming soon.

Thanks for all the work you do.

Best regards,

Chuck

I've committed a non-contiguous initial part of this series, omitting
patches where acks still look to be missing, and hence only up to a
point where I could be reasonably certain that the skipped patches
won't interact with later ones. If you can indicate which further
sufficiently reviewed/acked parts of the series are independent of
earlier parts which aren't fully ready yet, I'd be happy to throw in
more.

It's more than just review. I've expressed elsewhere that I'm not
convinced of the approach as a whole, complicating things further.
A re-work towards using ref-counting on the devices likely can't be
viewed as a re-submission (and hence likely won't qualify for 4.17
anymore at this point), but I think that's the only (long term)
viable path.

Well, obviously.

The replacement patch has gone in as 31b41ce858c8 ("x86/amd: only
call setup_force_cpu_cap for boot CPU").

Patch 7 was withdrawn, while I've committed patch 8 this morning.

Isn't this commit 755087eb9b10?

Afaict e83cd54611fe ("x86: Expose more MSR_ARCH_CAPS to hwdom").

19. [PATCH v2 00/12] x86: memcpy() / memset() (non-)ERMS flavors plus fallout
Status: Some parts committed, some parts entirely uncommented on.

20. [PATCH 0/2] x86/vMCE: address handling related adjustments
Status: Iirc no comments at all so far.

21: [PATCH v2 0/2] x86/mwait-idle: (remaining) SPR support
Status: Patch 1 still lacking an ack.

22: [PATCH v2 0/8] x86emul: a few small steps towards disintegration
Status: Iirc entirely ignored for about a year (since v1 submission).

23: [PATCH 00/11] x86: support AVX512-FP16
Status: v1 was reviewed, but some of the review comments need further
clarifying before I can sensibly make/submit v2.
Note: Depends on item 22 (albeit if absolutely necessary it could be
re-based ahead).

As per the XSA this isn't intended to be committed. If anything the
XSA may want re-issuing with this patch.

8. [PATCH v7 00/11] libs/guest: new CPUID/MSR interface
Status: Largely reviewed iirc, but there was something Andrew's input
was needed on, or he wasn't happy with.

9. [XEN PATCH 0/2] libxl: replace deprecated -sdl and -soundhw qemu options
Status: Patch 2 still having some discussion ongoing, i.e. as a
committer it's not clear to me whether the patch will want a minor
update.

v2 was a 3-patch series which has gone in already.

5. [PATCH 0/9] gnttab: further work from XSA-380 / -382 context
Status: Some parts are controversial, but this shouldn't prevent the
reviewing / progressing of non-controversial ones there (7-9).

6: [XEN PATCH v2 0/4] xen: rework compat headers generation
Status: The 3rd patch needs reviewing by someone speaking enough Perl.

PRINT() is also used in path for secondary bring-up. So this could be 
used after .init (even though today CPU hotplug doesn't work on Arm).

Furthermore, PRINT() is only used when earlyprintk is enabled. This 
should only be used in a development environment (gated by 
CONFIG_DEBUG). So I think it is better to keep all the strings in 
.rodata.str rather than trying to distinguish whether the caller will 
happen only during init on boot.

Then the term "earlyprintk" looks to be misleading?

Only now, when I'm about to backport this, it occurs to me to ask: Why

be gated upon HVM actually being in use (i.e. in particular CONFIG_HVM=y
in the first place)?

There is no basis for reverting, at this point at least. May I remind
you of the fact that Xen is a community project? I know you've done
reverts in the past without even waiting for a discussion to settle,
but this wasn't okay back then and is not going to be okay this time
round, nor going forward. If you see issues with a series, and in
particular one which is otherwise fully qualified for committing,
you ought to voice these concerns. You cannot expect people to guess
that you're still not happy with the adjustments which were made in
an attempt to address earlier voiced concerns.

> There has not been adequate review or testing.

No adequate review? Am I a 2nd class citizen all of the sudden? In my
reviews I've tried hard to account for the few comments you gave (or
should I say that Roger was able to shake out of you)? Plus I've said
more than once that I would prefer to not commit this without you
having given it a (perhaps just informal) look over. Yet no feedback
ever surfaced. I don't recall you going ...

... this far (and in particular not for the later versions of the
series), but I do recall Roger re-working the patch to (try to)
address your concerns. Going from just my mailbox (which goes back
only to v3) I see no replies from you _at all_ on this patch. There
was a longish reply to 0/3, but nothing on v4 or newer, despite
pings which were sent your way.

Knowing this has happened in the past - is your reaction based on v6
or rather on the last version you've actually looked at (presumably
v3)?

Yes. Which amounts to only VT-x being unsafe. And in particular PV alone
(e.g. shim, from the perspective of the shim itself) is safe as well, no
matter what CPU we're on.

Not sure - many of the settings (like X86_FEATURE_SC_RSB_HVM also being
set in the enclosing if()) only affect HVM-specific code paths, so which
way they are set wouldn't matter when !CONFIG_HVM. But the one here
clearly affects a common code path, for no gains at all. It's not an
overly hot code path, sure, but it still strikes me as odd.

Subject: [PATCH v2 2/3] xen/sched: carve out memory allocation and freeing from schedule_cpu_rm()
Date: Mon, 15 Aug 2022 13:04:09 +0200

In order to prepare not allocating or freeing memory from
schedule_cpu_rm(), move this functionality to dedicated functions.

For now call those functions from schedule_cpu_rm().

No change of behavior expected.

V2:
- add const (Jan Beulich)
- use "unsigned int" for loop index (Jan Beulich)
- use xmalloc_flex_struct() (Jan Beulich)
- use XFREE() (Jan Beulich)
- hold rcu lock longer (Jan Beulich)
- add ASSERT() (Jan Beulich)

For updating the node affinities of all domains in a cpupool add a new
function cpupool_update_node_affinity().

In order to avoid multiple allocations of cpumasks carve out memory
allocation and freeing from domain_update_node_affinity() into new
helpers, which can be used by cpupool_update_node_affinity().

Modify domain_update_node_affinity() to take an additional parameter
for passing the allocated memory in and to allocate and free the memory
via the new helpers in case NULL was passed.

This will help later to pre-allocate the cpumasks in order to avoid
allocations in stop-machine context.

Subject: [PATCH v2 3/3] xen/sched: fix cpu hotplug
Date: Mon, 15 Aug 2022 13:04:10 +0200

Cpu cpu unplugging is calling schedule_cpu_rm() via stop_machine_run()
with interrupts disabled, thus any memory allocation or freeing must
be avoided.

Since commit 5047cd1d5dea ("xen/common: Use enhanced
ASSERT_ALLOC_CONTEXT in xmalloc()") this restriction is being enforced
via an assertion, which will now fail.

Before that commit cpu unplugging in normal configurations was working
just by chance as only the cpu performing schedule_cpu_rm() was doing
active work. With core scheduling enabled, however, failures could
result from memory allocations not being properly propagated to other
cpus' TLBs.

Fix this mess by allocating needed memory before entering
stop_machine_run() and freeing any memory only after having finished
stop_machine_run().

Fixes: 1ec410112cdd ("xen/sched: support differing granularity in schedule_cpu_[add/rm]()")

Subject: [PATCH v2 0/3] xen/sched: fix cpu hotplug
Date: Mon, 15 Aug 2022 13:04:07 +0200
Message-Id: <20220815110410.19872-1-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

A recent change in the hypervisor memory allocation framework led to
crashes when unplugging host cpus.

This was due to the (correct) assertion that allocating and freeing
memory is allowed with enabled interrupts only. As the main cpu unplug
operation is done in stop-machine context, this assertion triggers in
debug builds.

Correct that by pre-allocating all needed memory while interrupts are
still on, and free memory after interrupts are enabled again.

Changes in V2:
- addressed all comments

Juergen Gross (3):
  xen/sched: introduce cpupool_update_node_affinity()
  xen/sched: carve out memory allocation and freeing from
    schedule_cpu_rm()
  xen/sched: fix cpu hotplug

Hi All,

It would appear this issue isn't specific to the Lenovo Yoga Slim 7 ProX, s=
omeone else in the Qubes community is having the same issue (https://github=
.com/QubesOS/qubes-issues/issues/7620#issuecomment-1209114810)

Can anyone shed some light on what possibly might be making a Xen 4.14 Hype=
rvisor crash after attempting to start a domU? Dom0 start's just fine, it '=
feels' like a memory violation or DMA/IOMMU issue, because the VM does succ=
essfully start, however 1 or 2 seconds after it successfully boot the mouse=
 (in dom0) locks up for 2-3 seconds and the entire device resets.

I can't seem to get any logs at all, xen's console, dom0 dmesg and domU's d=
mesg all appear to be fine in the lead up to the crash. I assume no one has=
 had a chance to use Xen on Ryzen 6000 (Rembrandt) yet due to the fact it's=
 hard to get your hands on with the chip shortage etc.

I'm hoping it's something that can be fixed with a cmdline flag, it's very =
frustrating having this shiny new laptop sitting on my desk :P

Cheers all

Well, to shed light on what's going on we need logged output, which I
understand isn't easy with laptops. Simply trying to guess what's
going wrong isn't very likely to lead us anywhere.

> Dom0 start's just fine, it 'feels' like a memory violation or DMA/IOMMU issue, because the VM does successfully start, however 1 or 2 seconds after it successfully boot the mouse (in dom0) locks up for 2-3 seconds and the entire device resets.

In the Qubes report there's talk of a 5s delay, which makes me assume
Xen crashes (or Dom0 reports itself crashed to Xen), which - unless
overridden - would result in a 5s delay (after logging state) until a
reboot would be attempted. This aspect could be verified by passing
"noreboot" on the Xen command line, in which case the device shouldn't
try to reboot itself at all. But all we'd learn from this is that
there's _some_ form of a crash (but not e.g. a triple fault), still
without knowing any details.

> I can't seem to get any logs at all, xen's console, dom0 dmesg and domU's dmesg all appear to be fine in the lead up to the crash. I assume no one has had a chance to use Xen on Ryzen 6000 (Rembrandt) yet due to the fact it's hard to get your hands on with the chip shortage etc.

... the initializer doesn't really look to be needed here, just like
you don't have one in cpupool_update_node_affinity(). The one thing
I'm not sure about is whether old gcc might mis-report a potentially
uninitialized variable with the initializer dropped ...

Repeating a v1 comment:

"At least from an abstract perspective, doesn't reading fields from
 sr require the RCU lock to be held continuously (i.e. not dropping

Initially I thought you did respond to this in some way, but when
looking for a matching reply I couldn't find one.

Well, it's certainly possible, but would require code to be written and an

overwritten.)

Hmm, interesting. "Protecting only the sr" then means what exactly?
Just its allocation, but not its contents?

Plus it's not just the pointers - sr->granularity also would better not
increase in the meantime ... Quite likely there's a reason why that also
cannot happen, yet even then I think a brief code comment might be
helpful here.

Well, I guess I need to leave this to the scheduler maintainers then. I
have to admit that it's not clear to me why all of sr->granularity,
sr->scheduler, or sr->sched_priv would be "cpupool specific". I may be
able to agree for sr->granularity, but the other two I thought was
scheduler data, not cpupool data. For sr->granularity in turn (but
perhaps also the other two fields) it's not obvious to me that pool
properties can't change in a racing manner.

Sadly indentation is now wrong here and ...

"reserved_device_memory". But I wouldn't mind names to be kept, just
as long as style constraints are met.

I don't mind the new placement, but I don't follow the reasoning.

This function is invoked indirectly via on_selected_cpus() (hence
the cf_check attribute) - I wonder how you get away without that for
HWP. Or else why we need this as a wrapper here when then you'd have
another similar wrapper elsewhere.

v1 added
void intel_feature_detect(void *info);
to acpi/cpufreq/processor_perf.h

v2 adds
void intel_feature_detect(struct cpufreq_policy *policy)
to acpi/cpufreq/cpufreq.h, which was selected to have the type available.

HWP calls hwp_init_msrs via on_selected_cpus, which then directly
calls intel_feature_detect().  ACPI needs the cf_check on
feature_detect, but intel_feature_detect is only called directly.

I thought it was necessary to keep the compiler happy.  Double
checking, you are correct that it is not needed.

Thanks,
Jason

I do, but the call sites should use the present name, so if anything
it would be the inline function that gets renamed. Yet I'm
deliberately using the same name, to kind of "hide" the actual
function (like we do elsewhere in a few cases). The effect you're
after would be implicitly had by going the route described in the
post-commit-message remark. I'd be happy to switch to that model, if
that suites you better.

It appears to be a memory violation error?

Thanks everyone!

Well, that only proves the sender, Juergen Gross, intended to send it to me.
So far, I have not found any evidence the message was delivered to my
Inbox. The evidence I have obtained so far in my filesystem and from my
e-mail provider and the messages I have received through my e-mail provider
is that the message was never delivered to my Inbox, and based on that
evidence, my current theory is that my e-mail service provider silently
dropped the message because it was signed. I will report the full findings
of my investigation here when my investigation is complete.

The only way I was able to respond to the message was by downloading
the mbox file from lore.kernel.org and importing it into my e-mail client.
So it is a fact that it was more difficult for me to respond and defend myself
against the attack that Juergen made against me because I had to go to the
trouble of finding the message on lore.kernel.org and import it into my
e-mail client instead of just using the ordinary procedure of replying to
a message I received in my Inbox.

Best regards,

Chuck

Yes, there's an attempt to access something which wasn't (successfully)
mapped. I expect there's a log message ahead of the actual crash telling
us what it was that was attempted to be mapped. A wild guess of mine
would be PCI MMCFG space. We may be able to read something out of the
system's ACPI tables, if you could extract them (at least DSDT, maybe
also SSDTs) into files. It would then also be useful to see the
hypervisor and kernel boot messages, at the very least to know where
certain things live in physical address space.

The code in arch/arm/traps.c has nothing arm32 specific like that so
could you explain this statement ?

Here the arm32 code will call the generic function which has only
something specific for BRK handling but the rest is generic.

I agree with that, I just do not understand your previous statement here.

Hi Thorsten,

I am forwarding this to you to help you cut through the noise. Unfortunately
the discussion of fixes for this regression has degenerated into ad hominum
attacks. I admit that I started complaining about the response of the
maintainers to this regression and now they are attacking me. I do apologize,
but I do not want to over-apologize. I do not apologize for trying to get
the fix for this regression rolling again. After all, it has been over three months
since the regression was first reported. I don't think I should be accused of
doing anything wrong just for asking for some transparency, honesty, and
a realistic estimate for how long it will take before a fix is committed from the
maintainers responsible for and working on a fix for this regression. I do want
you to provide some feedback here on the public mailing lists.

I present the following message which cuts out the noise and I think describes
fairly completely the problems that are preventing a fix for this regression from
getting merged into the mainline kernel. Can you weigh in with your opinion
about what should be done now?

Best regards,

Chuck

The statement is not related to the code but the console output. On 
arm64, a data abort will decode the HSR and provide a dump of the 
page-table walk.

This doesn't happen on arm32 because Xen will call do_unexpected_trap(). 
So the only information we have is the HSR and FAR. This is not very 
helpful for debugging page-table walk.

After this patch, the same information will be printed on arm32 and arm64.

Sorry for not replying earlier, I ignored this thread and all other
non-urgent mail in the past two weeks: I was on vacation until a few
days ago and when I came home I had to deal with some other stuff first.

Yeah, it's important to ensure regressions don't simply fall though the
cracks, but my advice in this case: let things rest for a few days now,
the right people have the issue on their radar again; give them time to
breath and work out a solution: it's not something that can be fixed
easily within a few minutes by one person alone, as previous discussions
have shown (also keep in mind that the merge window was open until
yesterday, which keeps many maintainers quite busy).

And FWIW: I've seen indicators that a solution to resolve this is
hopefully pretty close now.

Yes, things take/took to long, as a few things were far from ideal how
this regression was dealt with. But that happens sometimes, we're all
just humans and make errors. I did a few as well and learned a thing or
two from then. Due to that I'll do a few things slightly different in
the future to hopefully get similar situations resolved a lot quicker in
the future.

Actually, I was planning on letting things rest for another two weeks, so I am
totally in agreement with you here.

That's good to know. But I must ask, can you provide a link to a public
discussion that indicates a fix is close? Or do you know a fix is close
because of private discussions? That distinction is important to me
because open source software is much less useful to me if the solutions
to problems are not discussed openly (except, of course, for solutions
to security vulnerabilities that are not yet public).

For context, I wrote a patch to introduce SPDX tags starting from
arch/arm/*.c.

Julien rightfully pointed out that it should be added to our coding
style. He is right. Also as I was reading his replies, I realized there
are a couple of minor coding style things to agree as a group first.
I'll highlighted them here and suggested a proposal. I am happy to go
with the preference of the majority.


## comment format // vs /*

In this patch I used:
// SPDX-License-Identifier: GPL-2.0

But our comment format is actually /* xxx */. I think it is fair to
use /* xxx */ as Julien requested:

/* SPDX-License-Identifier: GPL-2.0 */

Unless there are any concerns, I'll change the patch to /* SPDX... */


## blank line after SPDX

In this series, I didn't add a blank line after the new SPDX comment, no
matter if the following line was an #include or another comment. Now I am
thinking it would be best to add a blank line, as follows:

---
/* SPDX-License-Identifier: GPL-2.0 */

#include <xen/bitops.h>
---

Or:

---
/* SPDX-License-Identifier: GPL-2.0 */

/*
 * xen/arch/arm/device.c
 *
---

Let me know if that's OK for you.


## Original copyright text

As we add the new SDPX tag, It makes sense to remove the older copyright
text at the top of the file, e.g.:

diff --git a/xen/arch/arm/alternative.c b/xen/arch/arm/alternative.c
index f03cd943c6..d0a409e4fd 100644
--- a/xen/arch/arm/alternative.c

 #include <xen/init.h>


Now the question is whether we want to keep what's left:

/*
 * alternative runtime patching
 * inspired by the x86 version
 *
 * Copyright (C) 2014-2016 ARM Ltd.
 */

The Copyright line is not useful and often stale. Also the other comment
is not very interesting in most cases (I am referring to "alternative
runtime patching inspired by the x86 version"), although I realize this
is going to be a on case-by-case basis.

My suggestion is to get rid of it all unless useful (in most cases it is
not useful), leading to:


diff --git a/xen/arch/arm/alternative.c b/xen/arch/arm/alternative.c

Do you guys agree?


Cheers,

P.S.
Julien, I'll reply to your other points separately to avoid confusion.

I used the information in COPYING at the top of the repository. I
realize that I should also have checked the comment header at the top
of each source file, especially in regards to GPLv2 vs, GPLv2 or later.
I'll do that in the next version.

Excellent point. I realized there are a couple of style details to sort
out so I sent out a separate email about that.

I agree. Also I made a comment about this in the other larger thread to

copyright/license headers at the top of the files to make sure they
match the SPDX tag.

Thanks for spotting this.

The code in free_heap_pages() will try to merge pages with the
successor/predecessor if pages are suitably aligned. So if the pages
reserved are right next to the pages given to the heap allocator,
free_heap_pages() will merge them, and give the reserved pages to heap
allocator accidentally as a result.

So in order to avoid the above scenario, this commit updates free_heap_pages()
to check whether the predecessor and/or successor has PGC_static set,
when trying to merge the about-to-be-freed chunk with the predecessor
and/or successor.

Subject: [PATCH v10 0/9] populate/unpopulate memory when domain on static allocation
Date: Tue, 16 Aug 2022 10:36:49 +0800
Message-Id: <20220816023658.3551936-1-Penny.Zheng@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0

Today when a domain unpopulates the memory on runtime, they will always
hand the memory over to the heap allocator. And it will be a problem if it
is a static domain.
Pages used as guest RAM for static domain shall always be reserved to this
domain only, and not be used for any other purposes, so they shall never go
back to heap allocator.

This patch serie intends to fix this issue, by adding pages on the new list
resv_page_list after having taken them off the "normal" list, when unpopulating
memory, and retrieving pages from resv page list(resv_page_list) when
populating memory.

---
v10 changes:
- let Arm keep #define PGC_static 0 private, with the generic fallback
remaining in page_alloc.c
- change ASSERT(d) to ASSERT_UNREACHABLE() to be more robust looking
forward, and also add a printk() to log the problem
- mention the the removal of #ifdef CONFIG_STATIC_MEMORY in commit
message
- commit message typo fix
- Do not skip the list addition in that one special case
- add lock on the fail path
- new commit "xen: rename free_staticmem_pages to unprepare_staticmem_pages"
---
v9 changes:
- move free_domheap_page into else-condition
- considering scrubbing static pages, domain dying case and opt_scrub_domheap
both do not apply to static pages.
- as unowned static pages don't make themselves to free_domstatic_page
at the moment, remove else-condition and add ASSERT(d) at the top of the
function
- remove macro helper put_static_page, and just expand its code inside
free_domstatic_page
- Use ASSERT_ALLOC_CONTEXT() in acquire_reserved_page
- Add free_staticmem_pages to undo prepare_staticmem_pages when
assign_domstatic_pages fails
- Remove redundant static in error message
---
v8 changes:
- introduce new helper free_domstatic_page
- let put_page call free_domstatic_page for static page, when last ref
drops
- #define PGC_static zero when !CONFIG_STATIC_MEMORY, as it is used
outside page_alloc.c
- #ifdef-ary around is_domain_using_staticmem() is not needed anymore
- order as a parameter is not needed here, as all staticmem operations are
limited to order-0 regions
- move d->page_alloc_lock after operation on d->resv_page_list
- As concurrent free/allocate could modify the resv_page_list, we still
need the lock
---
v7 changes:
- protect free_staticmem_pages with heap_lock to match its reverse function
acquire_staticmem_pages
- IS_ENABLED(CONFIG_STATIC_MEMORY) would not be needed anymore
- add page on the rsv_page_list *after* it has been freed
- remove the lock, since we add the page to rsv_page_list after it has
been totally freed.
---
v6 changes:
- rename PGC_staticmem to PGC_static
- remove #ifdef aroud function declaration
- use domain instead of sub-systems
- move non-zero is_domain_using_staticmem() from ARM header to common
header
- move PGC_static !CONFIG_STATIC_MEMORY definition to common header
- drop the lock before returning
---
v5 changes:
- introduce three new commits
- In order to avoid stub functions, we #define PGC_staticmem to non-zero only
when CONFIG_STATIC_MEMORY
- use "unlikely()" around pg->count_info & PGC_staticmem
- remove pointless "if", since mark_page_free() is going to set count_info
to PGC_state_free and by consequence clear PGC_staticmem
- move #define PGC_staticmem 0 to mm.h
- guard "is_domain_using_staticmem" under CONFIG_STATIC_MEMORY
- #define is_domain_using_staticmem zero if undefined
- extract common codes for assigning pages into a helper assign_domstatic_pages
- refine commit message
- remove stub function acquire_reserved_page
- Alloc/free of memory can happen concurrently. So access to rsv_page_list
needs to be protected with a spinlock
---
v4 changes:
- commit message refinement
- miss dropping __init in acquire_domstatic_pages
- add the page back to the reserved list in case of error
- remove redundant printk
- refine log message and make it warn level
- guard "is_domain_using_staticmem" under CONFIG_STATIC_MEMORY
- #define is_domain_using_staticmem zero if undefined
---
v3 changes:
- fix possible racy issue in free_staticmem_pages()
- introduce a stub free_staticmem_pages() for the !CONFIG_STATIC_MEMORY case
- move the change to free_heap_pages() to cover other potential call sites
- change fixed width type uint32_t to unsigned int
- change "flags" to a more descriptive name "cdf"
- change name from "is_domain_static()" to "is_domain_using_staticmem"
- have page_list_del() just once out of the if()
- remove resv_pages counter
- make arch_free_heap_page be an expression, not a compound statement.
- move #ifndef is_domain_using_staticmem to the common header file
- remove #ifdef CONFIG_STATIC_MEMORY-ary
- remove meaningless page_to_mfn(page) in error log
---
v2 changes:
- let "flags" live in the struct domain. So other arch can take
advantage of it in the future
- change name from "is_domain_on_static_allocation" to "is_domain_static()"
- put reserved pages on resv_page_list after having taken them off
the "normal" list
- introduce acquire_reserved_page to retrieve reserved pages from
resv_page_list
- forbid non-zero-order requests in populate_physmap
- let is_domain_static return ((void)(d), false) on x86
- fix coding style

PGC_reserved could be ambiguous, and we have to tell what the pages are
reserved for, so this commit intends to rename PGC_reserved to
PGC_static, which clearly indicates the page is reserved for static
memory.

Subject: [PATCH v10 2/9] xen: do not free reserved memory into heap

Pages used as guest RAM for static domain, shall be reserved to this
domain only.
So in case reserved pages being used for other purpose, users
shall not free them back to heap, even when last ref gets dropped.

This commit introduces a new helper free_domstatic_page to free
static page in runtime, and free_staticmem_pages will be called by it
in runtime, so let's drop the __init flag.

Wrapper #ifdef CONFIG_STATIC_MEMORY around function declaration(
free_staticmem_pages, free_domstatic_page, etc) is kinds of redundant,
so we decide to remove it here.

v10 changes:
- let Arm keep #define PGC_static 0 private, with the generic fallback
remaining in page_alloc.c
- change ASSERT(d) to ASSERT_UNREACHABLE() to be more robust looking
forward, and also add a printk() to log the problem
- mention the removal of #ifdef CONFIG_STATIC_MEMORY in commit message
---
v9 changes:
- move free_domheap_page into else-condition
- considering scrubbing static pages, domain dying case and opt_scrub_domheap
both donot apply to static pages.
- as unowned static pages don't make themselves to free_domstatic_page
at the moment, remove else-condition and add ASSERT(d) at the top of the
function
---
v8 changes:
- introduce new helper free_domstatic_page
- let put_page call free_domstatic_page for static page, when last ref
drops
- #define PGC_static zero when !CONFIG_STATIC_MEMORY, as it is used
outside page_alloc.c
---
v7 changes:
- protect free_staticmem_pages with heap_lock to match its reverse function
acquire_staticmem_pages
---
v6 changes:
- adapt to PGC_static
- remove #ifdef aroud function declaration
---
v5 changes:
- In order to avoid stub functions, we #define PGC_staticmem to non-zero only
when CONFIG_STATIC_MEMORY
- use "unlikely()" around pg->count_info & PGC_staticmem
- remove pointless "if", since mark_page_free() is going to set count_info
to PGC_state_free and by consequence clear PGC_staticmem
- move #define PGC_staticmem 0 to mm.h
---
v4 changes:
- no changes
---
v3 changes:
- fix possible racy issue in free_staticmem_pages()
- introduce a stub free_staticmem_pages() for the !CONFIG_STATIC_MEMORY case
- move the change to free_heap_pages() to cover other potential call sites
- fix the indentation
---
v2 changes:
- new commit

With more and more CDF_xxx internal flags in and to save the space, this
commit introduces a new field "flags" in struct domain to store CDF_*
internal flags directly.

Another new CDF_xxx will be introduced in the next patch.

In order to have an easy and quick way to find out whether this domain memory
is statically configured, this commit introduces a new flag CDF_staticmem and a
new helper is_domain_using_staticmem() to tell.

Subject: [PATCH v10 6/9] xen: unpopulate memory when domain is static
Date: Tue, 16 Aug 2022 10:36:55 +0800

Today when a domain unpopulates the memory on runtime, they will always
hand the memory back to the heap allocator. And it will be a problem if domain
is static.

Pages as guest RAM for static domain shall be reserved to only this domain
and not be used for any other purposes, so they shall never go back to heap
allocator.

This commit puts reserved pages on the new list resv_page_list only after
having taken them off the "normal" list, when the last ref dropped.

v10 change:
- Do not skip the list addition in that one special case
---
v9 change:
- remove macro helper put_static_page, and just expand its code inside
free_domstatic_page
---
v8 changes:
- adapt this patch for newly introduced free_domstatic_page
- order as a parameter is not needed here, as all staticmem operations are
limited to order-0 regions
- move d->page_alloc_lock after operation on d->resv_page_list
---
v7 changes:
- Add page on the rsv_page_list *after* it has been freed
---
v6 changes:
- refine in-code comment
- move PGC_static !CONFIG_STATIC_MEMORY definition to common header
---
v5 changes:
- adapt this patch for PGC_staticmem
---
v4 changes:
- no changes
---
v3 changes:
- have page_list_del() just once out of the if()
- remove resv_pages counter
- make arch_free_heap_page be an expression, not a compound statement.
---
v2 changes:
- put reserved pages on resv_page_list after having taken them off
the "normal" list

The name of free_staticmem_pages is inappropriate, considering it is
the opposite of function prepare_staticmem_pages.

Rename free_staticmem_pages to unprepare_staticmem_pages.

Subject: [PATCH v10 7/9] xen: introduce prepare_staticmem_pages
Date: Tue, 16 Aug 2022 10:36:56 +0800

Later, we want to use acquire_domstatic_pages() for populating memory
for static domain on runtime, however, there are a lot of pointless work
(checking mfn_valid(), scrubbing the free part, cleaning the cache...)
considering we know the page is valid and belong to the guest.

This commit splits acquire_staticmem_pages() in two parts, and
introduces prepare_staticmem_pages to bypass all "pointless work".

When a static domain populates memory through populate_physmap at runtime,
it shall retrieve reserved pages from resv_page_list to make sure that
guest RAM is still restricted in statically configured memory regions.
This commit also introduces a new helper acquire_reserved_page to make it work.

Signed-off-by: Penny Zheng <penny.zheng@arm.com>
---
v10 changes:
- add lock on the fail path
---
v9 changes:
- Use ASSERT_ALLOC_CONTEXT() in acquire_reserved_page
- Add free_staticmem_pages to undo prepare_staticmem_pages when
assign_domstatic_pages
- Remove redundant static in error message
---
v8 changes:
- As concurrent free/allocate could modify the resv_page_list, we still
need the lock
---
v7 changes:
- remove the lock, since we add the page to rsv_page_list after it has
been totally freed.
---
v6 changes:
- drop the lock before returning
---
v5 changes:
- extract common codes for assigning pages into a helper assign_domstatic_pages
- refine commit message
- remove stub function acquire_reserved_page
- Alloc/free of memory can happen concurrently. So access to rsv_page_list
needs to be protected with a spinlock
---
v4 changes：
- miss dropping __init in acquire_domstatic_pages
- add the page back to the reserved list in case of error
- remove redundant printk
- refine log message and make it warn level
---
v3 changes:
- move is_domain_using_staticmem to the common header file
- remove #ifdef CONFIG_STATIC_MEMORY-ary
- remove meaningless page_to_mfn(page) in error log
---
v2 changes:
- introduce acquire_reserved_page to retrieve reserved pages from
resv_page_list
- forbid non-zero-order requests in populate_physmap
- let is_domain_static return ((void)(d), false) on x86

The initial observation were duplicate symbols that our checking warns
about. Instead of merely renaming one or both pair(s) of symbols,
reduce #ifdef-ary at the same time by moving the instantiation of the
arrays into a macro. While doing the conversion also stop open-coding
array_access_nospec().

v2: Use single-macro approach.

For the message to be useful as a hint if the assertion triggers, it
wants printing ahead of the assertion. I also think it wants to be a
XENLOG_G_* kind of log level, so it would be rate limited by default
in release builds. Just to be on the safe side. (I'm not in favor of
the log message in the first place, but I do know that Julien had
asked for one.)

Andrew, please, come on. I have not added any tags from you, hence I
cannot possibly have falsified any. The Suggested-by tags had been
there all the time. I also cannot see any evidence of "the series not
[having] been reviewed correctly". Please can you support your claims
by actual facts?

As to the series itself and its possible reverting (or fixing) - can
you please reply with technical comments on the problematic patch(es)
of the most recent version?

Henry - you may want to add this to your list of things to monitor.
The situation will need resolving one way or another, but obviously
we first need to determine the most suitable way.

Subject: [PATCH] x86/entry: fix entry_INT80_compat for Xen PV guests
Date: Tue, 16 Aug 2022 09:11:37 +0200
Message-Id: <20220816071137.4893-1-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Commit c89191ce67ef ("x86/entry: Convert SWAPGS to swapgs and remove
the definition of SWAPGS") missed one use case of SWAPGS in
entry_INT80_compat. Removing of the SWAPGS macro led to asm just
using "swapgs", as it is accepting instructions in capital letters,
too.

This in turn leads to splats in Xen PV guests like:

[   36.145223] general protection fault, maybe for address 0x2d: 0000 [#1] PREEMPT SMP NOPTI
[   36.145794] CPU: 2 PID: 1847 Comm: ld-linux.so.2 Not tainted 5.19.1-1-default #1 openSUSE Tumbleweed f3b44bfb672cdb9f235aff53b57724eba8b9411b
[   36.146608] Hardware name: HP ProLiant ML350p Gen8, BIOS P72 11/14/2013
[   36.148126] RIP: e030:entry_INT80_compat+0x3/0xa3

Fix that by open coding this single instance of the SWAPGS macro.

Hmm, looking more closely it's the sound device which is being opened by
some ALSA process. I have no clue at all why this would happen while
starting a VM. If the firmware setup allows you to, you may want to try
turning off that device and see if then the VM starts successfully.

> Could it be a misconfiguration with ACPI tables? I originally thought it could be AMD's SEV but I think it might just be that Xen is attempting to use a memory region that it shouldn't

No, it's clearly ACPI which tries to evaluate / modify something. That's not
initiated by Xen at all. It's merely likely that under Xen something works
differently than under native. As said, since now you're able to see log
output on the screen, quite likely you would also see an earlier message
about some mapping operation having failed. Whether that would be a Xen or
kernel message (or both) is uncertain, as it would depend on the specific
operation that is being attempted.

"The HD Audio Controller" is somewhat ambiguous - according to lspci
apparently you've got three of them, one named as "multimedia controller"
(and hence likely having functions beyond just sound).

In any event we still need to figure out what ACPI is trying to do when
the controller is being "opened" and why that doesn't work under Xen.

Subject: [PATCH v2 0/4] Make balloon drivers memory changes known to the rest of the kernel
Date: Tue, 16 Aug 2022 12:41:13 +0300
Message-Id: <20220816094117.3144881-1-alexander.atanasov@virtuozzo.com>
X-Mailer: git-send-email 2.31.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Currently balloon drivers (Virtio,XEN, HyperV, VMWare, ...)
inflate and deflate the guest memory size but there is no
way to know how much the memory size is changed by them.

A common use of the ballooning is to emulate [1]
hot plug and hot unplug - due to the complexity of the later.
Hotplug has a notifier and one can also check the updated
memory size.

To improve this add InflatedTotal and InflatedFree
to /proc/meminfo and implement a balloon notifier.

Amount of inflated memory can be used:
 - si_meminfo(..) users can improve calculations
 - adjust cache/buffer sizes 
 - adjust object/connection limits
 - as a hint for the oom a killer
 - by user space software that monitors memory pressure

Patches for the other balloon drivers will be done next.

Alexander Atanasov (4):
  Make place for common balloon code
  Enable balloon drivers to report inflated memory
  Display inflated memory to users
  drivers: virtio: balloon - update inflated memory

Cpu cpu unplugging is calling schedule_cpu_rm() via stop_machine_run()
with interrupts disabled, thus any memory allocation or freeing must
be avoided.

Since commit 5047cd1d5dea ("xen/common: Use enhanced
ASSERT_ALLOC_CONTEXT in xmalloc()") this restriction is being enforced
via an assertion, which will now fail.

Before that commit cpu unplugging in normal configurations was working
just by chance as only the cpu performing schedule_cpu_rm() was doing
active work. With core scheduling enabled, however, failures could
result from memory allocations not being properly propagated to other
cpus' TLBs.

Fix this mess by allocating needed memory before entering
stop_machine_run() and freeing any memory only after having finished
stop_machine_run().

Fixes: 1ec410112cdd ("xen/sched: support differing granularity in schedule_cpu_[add/rm]()")

Subject: [PATCH v3 1/3] xen/sched: introduce cpupool_update_node_affinity()
Date: Tue, 16 Aug 2022 12:13:15 +0200
Message-Id: <20220816101317.23014-2-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
In-Reply-To: <20220816101317.23014-1-jgross@suse.com>

For updating the node affinities of all domains in a cpupool add a new
function cpupool_update_node_affinity().

In order to avoid multiple allocations of cpumasks carve out memory
allocation and freeing from domain_update_node_affinity() into new
helpers, which can be used by cpupool_update_node_affinity().

Modify domain_update_node_affinity() to take an additional parameter
for passing the allocated memory in and to allocate and free the memory
via the new helpers in case NULL was passed.

This will help later to pre-allocate the cpumasks in order to avoid
allocations in stop-machine context.

V2:
- move helpers to core.c (Jan Beulich)
- allocate/free memory in domain_update_node_aff() if NULL was passed
  in (Jan Beulich)
V3:
- remove pointless initializer (Jan Beulich)

Subject: [PATCH v3 0/3] xen/sched: fix cpu hotplug
Date: Tue, 16 Aug 2022 12:13:14 +0200
Message-Id: <20220816101317.23014-1-jgross@suse.com>

A recent change in the hypervisor memory allocation framework led to
crashes when unplugging host cpus.

This was due to the (correct) assertion that allocating and freeing
memory is allowed with enabled interrupts only. As the main cpu unplug
operation is done in stop-machine context, this assertion triggers in
debug builds.

Correct that by pre-allocating all needed memory while interrupts are
still on, and free memory after interrupts are enabled again.

Changes in V3:
- addressed all comments

Changes in V2:
- addressed all comments

Juergen Gross (3):
  xen/sched: introduce cpupool_update_node_affinity()
  xen/sched: carve out memory allocation and freeing from
    schedule_cpu_rm()
  xen/sched: fix cpu hotplug

Subject: [PATCH v3 2/3] xen/sched: carve out memory allocation and freeing from schedule_cpu_rm()
Date: Tue, 16 Aug 2022 12:13:16 +0200

In order to prepare not allocating or freeing memory from
schedule_cpu_rm(), move this functionality to dedicated functions.

For now call those functions from schedule_cpu_rm().

No change of behavior expected.

V2:
- add const (Jan Beulich)
- use "unsigned int" for loop index (Jan Beulich)
- use xmalloc_flex_struct() (Jan Beulich)
- use XFREE() (Jan Beulich)
- hold rcu lock longer (Jan Beulich)
- add ASSERT() (Jan Beulich)
V3:
- added comment for schedule_cpu_rm_alloc() (Jan Beulich)

Subject: [XEN PATCH] build: Fix x86 build without EFI
Date: Tue, 16 Aug 2022 11:30:43 +0100
Message-ID: <20220816103043.32662-1-anthony.perard@citrix.com>
X-Mailer: git-send-email 2.30.2
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Content-Type: text/plain

We can't have a source file with the same name that exist in both the
common code and in the arch specific code for efi/. This can lead to
comfusion in make and it can pick up the wrong source file. This issue
lead to a failure to build a pv-shim for x86 out-of-tree, as this is
one example of an x86 build using the efi/stub.c.

The issue is that in out-of-tree, make might find x86/efi/stub.c via
VPATH, but as the target needs to be rebuilt due to FORCE, make
actually avoid changing the source tree and rebuilt the target with
VPATH ignored, so $@ lead to the build tree where "stub.c" dosen't
exist yet so a link is made to "common/stub.c".

Rework the new common/stub.c file to have a different name than the
already existing one. And build both *stub.c as two different objects.
This mean we have to move some efi_compat_* aliases which are probably
useless for Arm.

Avoid using $(EFIOBJ-y) as an alias for $(clean-files), add
common_stub.c directly to $(clean-files).

Fixes: 7f96859b0d00 ("xen: reuse x86 EFI stub functions for Arm")

For the cflag addition in non-ARM_EFI, I was tempted to apply it to
the whole directory instead of just stub.o. (Even if there's only a
single object). I think that would be enough to overwrite the
-fshort-wchar from efi-common.mk, but I forgot what cflags come after
that. But adding it to just one object mean that it's added at the
last possible moment.

This patch probably need a slight better subject, as the issue is only
with out-of-tree build. So new subject:
    build: Fix x86 out-of-tree build without EFI

I haven't looked at the rest of the patch. However, I think you also 
want to update .gitignore to excluse arch/*/efi/common_stub.c.

Also, I am thinking to drop my patch [1] which update .gitignore as this 
will become moot with this change. Let me know what you think.

Cheers,

I'd like to keep an eye on any changes in the Makefiles, to avoid
further break of the build system.

With this entries, it means that THE REST will not be CCed anymore for
changes in
- xen/Makefile
- xen/*.mk
- xen/scripts/Kbuild.include
- xen/scripts/Makefile.*
This could be an issue.

Most other files are also listed in other sections so would have a
maintainer. There's probably a few Makefiles in subdirectory that
would have CC THE REST but won't with this new section.

I'm not sure if adding a maintainers would be needed, but maybe Jan?

I could look at using lei from public-inbox, or just the search from
public-inbox, but it's easier to tell people to CC me.

Thanks.

The only way I can currently explain all aspects of the behavior that
I'm aware of is for Dom0's kernel somehow not identifying the page
that ACPI wants to map (via ioremap_cache()) as identity mapped. As
far as ACPI goes, this is what I read out of the tables:

In SSDT27.dsl we have

    Scope (\_SB.PCI0.GP17.AZAL)
    {
        Method (_PS0, 0, NotSerialized)  // _PS0: Power State 0
        {
            Acquire (\M27E, 0xFFFF)
            M460 ("FEA-ASL-\\_SB.PCI0.PBC.AZAL._PS0 CpmAzaliaPresentState = 1\n", Zero, Zero, Zero, Zero, Zero, Zero)
            M279 = One
            M276 ()
            Release (\M27E)
        }

M276() then invokes

                Local0 = M017 (Zero, 0x08, One, 0x19, Zero, 0x08)

with M017() located in SSDT16.dsl:

    Method (M017, 6, Serialized)
    {
        Local0 = M083 /* \M083 */
        Local1 = (M083 >> 0x14)
        Local2 = (Local1 & 0x0F00)
        Local2 += 0x0100
        If (((Local1 + Arg0) >= Local2))
        {
            Local3 = 0x7FFFFFFF
            Local3 |= 0x80000000
            Local4 = ((Local3 >> Arg4) & (Local3 >> (0x20 - Arg5)
                ))
            Return (Local4)
        }

        Local0 += (Arg0 << 0x14)
        Local0 += (Arg1 << 0x0F)
        Local0 += (Arg2 << 0x0C)
        Return (M013 (Local0, Arg3, Arg4, Arg5))
    }

M013 carries out the actual memory access (32 bits at offset 0x19 from
Local0 that was determined here; oddly enough a mis-aligned access,
but that itself isn't a problem). The base address therefore is M083
offset by (0 << 0x14) + (8 << 0xf) + (1 << 0xc) = 0x41000 if I got
things right.

M083 in turn is a field in

    OperationRegion (CPNV, SystemMemory, 0x7AF67018, 0x000100F7)
    Field (CPNV, AnyAcc, Lock, Preserve)
    {
        M082,   32, 
        M083,   32, 
        M084,   32, 
        ...

so the first few words of machine memory at 0x7af67018 would be of
interest (assuming of course that address doesn't change across
boots). 0x7af67018 itself is within the ACPI NVS range. Could you
perhaps obtain this from one of the /proc or /sys interfaces (perhaps
from a native kernel), or should I make a debugging patch for the
hypervisor? (Making one right away, with further logging added,
doesn't seem useful until it's clear whether you can actually also
observe output slightly before the actual crash, which has a risk of
being overwritten or scrolling off the screen.)

The situation of course isn't helped by the kernel's PFN <-> MFN
translation asymmetry in pte_pfn_to_mfn() nor pte_mfn_to_pfn()'s
anomaly (as already noted over two years ago in
https://lists.xen.org/archives/html/xen-devel/2020-05/msg00549.html),
albeit the exception error code suggests that the former is what is
getting in the way (and what would then also result in entirely
silent mapping failure). While I would like to patch the kernel at
least as much for the PFN/MFN to survive and hence appear in the page
table entry dump associated with the page fault, I'm afraid the
resulting entry could be recognized as a swap one. Such a patch could
hence only be used for debugging purposes when no swap space is in
use.

These useless aliases want avoiding there imo. Already when the original
series was discussed, I requested to avoid introduction of a file named
common-stub.c or alike. If names need to be different, can't we follow
boot.c's model and introduce a per-arch efi/stub.h which stub.c would
include at a suitable position (and which right now would be empty for
Arm)?

At the very least I'd like to request to avoid the underscore in the
file name.

Which brought me to this message, which looks like Boris applied a
slightly(?) modified version of Jan's patch to a branch that afaik is
regularly pushed to Linus:
https://lore.kernel.org/all/166055884287.401.612271624942869534.tip-bot2@tip-bot2/

So unless problems show up in linux-next I expect this will land in
master soon (and a bit later be backported to stable due to the CC
stable tag).

You IMHO are expecting a bit too much here IMHO. Solutions to problems
in open source software get discussed on various, sometimes private
channels all the time. Just take conferences for example, where people
discuss them during talks, meetings, or in one-to-ones over coffee;
sometimes they are the only way to solve complex problems. But as you
can see from above link it's not like anybody is trying to sneak things
into the kernel.

Ciao, Thorsten

Yeah, I've notice that. This is why the build is broken under
specific condition.

That seems to be possible. But how is it better than having two
different source file? The only thing is to avoid exporting the
efi_compat_* symbol aliases. The downside is we would have another weird
looking not really header which is actually just part of a source file.
At least, "stub.c" and "stub.h" would be two different names, we just
change the extension rather than the basename.

Cheers,

OK, that's exactly the kind of thing I am looking for. It would be
nice if regzbot could have found that patch in that tree and
display it in the web interface as a notable patch. Currently,
regzbot is only linking to a dead patch that does not even fix
the regression as a notable patch associated with this regression.

If regzbot is not yet smart enough to find it, could you take the
time to manually intervene with a regzbot command so that
patch is displayed as a notable patch for this regression?

Well, as a user of Linux, I would like to see more of those discussions in
the open, especially if they relate directly to a fix of a regression tracked
by regzbot. it would be helpful for me to decide questions such as, does
it make sense for me to keep using the foo project to provide a feature,
or should I switch to project baz that provides the same feature?

In any case, watching what Linus actually chooses to commit into
mainline gives me a pretty good clue about such questions.

Best regards,

Chuck

As said - I think they're wrong to have in Arm. But if Arm maintainers
don't care about them being there, so be it. As long as they don't
voice a view, I guess as the EFI maintainer I can sensibly ask for
them to be avoided in a reasonably clean way.

Whether that's "weird" is certainly a matter of taste ... To me,
common-stub.c also comes close  to "weird", fwiw. But as I've tried
to express, if I'm the only one disliking common-stub.c, then please
ignore my view and I'll nevertheless ack the resulting patch. (That
said, I view the vpath issue causing the problem as really the one
that would want tackling. There shouldn't be a requirement for
files to have different names as long as they live in different
directories.)

regzbot will notice when the patch hit's Linux next, where many changes
land and hang around for a few days before they hit mainline. Watching
all the different development trees would be possible and would catch
this patch earlier, but I'm not sure that's worth the work. Maybe
regzbot will do that one day, but there are more important missing
features on my todo list for now.

Ciao, Thorsten

IIUC, regzbot might not notice because the patch lacks a Link: tag
to the original regression report. The Link tag is to Jan's patch
that was posted sometime in April, I think, which also lacks the
Link tag to the original report of the regression which did not
happen until May 4. If regzbot is smart enough to notice that the
patch also has a Fixes: tag for the commit that was identified as
bad in the original regression report, then I expect regzbot will
find it.

Best regards,

Chuck

Hi,

I think you should change the title to "xsm/flask: Boot-time labeling
for multiple domains".  Refactor implies no functional change, and
this is a functional change.  With this, I think the commit message
should be re-written to focus on the "why" of the new labeling policy.

The problem this commit is addressing is "flask can only label a
single dom0_t at boot, and this is incompatible with dom0less and
hyperlaunch".

ISTM that dom0less device tree could gain a node for the security
label, and Hyperlaunch already supports labels.  But a goal of this
patch is to make it work without changing dom0less?  And it may be
worth more directly stating that dom0less panics today since the domU
fails to build with unlabeled_t.

Also a motivation was to align Flask labels to match the dummy policy
with dom0/domU, correct?  That would be worth adding.

AFAICT, the labeling policy needs to handle these three cases:
1) Traditional domain 0 (x86 or arm)
Single domain - domid == 0 && privileged

2) dom0less (arm)
Possibly a single dom0 - domid == 0 && privileged
Multiple domUs - domid > 0 && not privileged
Notably, it takes care not to create a domU with domid 0.

3) Hyperlaunch (x86 or arm)
Potentially anything?  I don't know what you envision for this.

When it was only dom0, it was easy to put a heuristic in flask to
label the first domain as dom0_t.  With dom0less, the heuristic can be
expanded to include domid > 0 -> domU_t.  With hyperlaunch, I'm not
sure.  Is there something it needs that wouldn't be covered?

dom0_t being a singleton emphasized for me that using only
is_privileged for the check isn't quite right.  Does hyperlaunch need
domid != 0 && is_privileged to get assigned dom0_t?  That could still
be done explicitly, but just not implicitly by the above.

I suppose if someone doesn't want to use domU_t/dom0_t, then they
could remove the xenboot_t allow rules which would defacto require
explicit labels.

The policy outlined above would change this line to:

This old check only applied at boot time to label the first domain as
dom0_t, but it didn't restrict runtime labeling...

...this new one restricts runtime labeling with dom0_t.  It's an
unusual case, so making the code change is (probably) fine.   But it
should at least be mentioned in the commit message.

However, if the boot time policy adds "domid == 0" to the dom0_t
assignment, then the dom0_created code can go away.

Jason

Hi Boris,

I see you have signed off on Jan's patch with a slight modification as
the short-term fix that is also tagged to be backported to stable. Thank you!
I hope no other problems or objections pop up and Linus will merge it into
the mainline kernel soon. Please forgive me for my impatience.

Best regards,

Chuck

Subject: [PATCH for-4.17] xen/arm: Support properly __ro_after_init on Arm
Date: Tue, 16 Aug 2022 19:59:54 +0100
Message-Id: <20220816185954.31945-1-julien@xen.org>
X-Mailer: git-send-email 2.37.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

From: Julien Grall <jgrall@amazon.com>

__ro_after_init was introduced recently to prevent modifying
some variables after init.

At the moment, on Arm, the variables will still be accessible
because the region permission is not updated.

Address that, but moving the sections .data.ro_after_init
out of .data and then mark the region read-only once we finish
to boot.

Signed-off-by: Julien Grall <jgrall@amazon.com>

This patch is targeting Xen 4.17. There are quite a few arm
specific variables that could be switch to use __ro_after_init.

This is not addressed by the commit. We could consider to switch
some of them for Xen 4.17. So the benefits for now is any common
variables using __ro_after_init.

I don't know if we need to go as far as the LICENSES directory. For
example, Zephyr doesn't have anything of the sort AFAICT. But maybe it
is cleaner to have it?

For the hypervisor, GPL-2.0 and GPL-2.0-or-later are the ones that are
relevant so we would only need LICENSES/preferred/GPL-2.0 initially?

I don't think that we need agreement from the original implementer to
remove the copyright: the copyright information is expressed by the
Signed-off-by line. In fact, every person that changed the file has
partial copyright ownership over it. So I think that we can remove the
Copyright line without asking anyone, as long as we properly retain the
git history.

That said, I am all for preventing troubles and rounds of questions,
especially as we need to change very many files. The more mechanical the
changes the better at this stage.

So maybe it is actually better to only remove the strict necessary (the
license info) and keep everything else. This way it could be almost
scriptable and it is easier to review too.

Any further changes could be done with additional patches on top. I am
going to do that if everyone agrees.

Subject: [PATCH 01/16] libxl: Add support for Virtio disk configuration
Date: Wed, 17 Aug 2022 10:06:46 +0800
Message-Id: <20220817020701.27379-1-jiamei.xie@arm.com>
X-Mailer: git-send-email 2.25.1

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-disk backend (emulator) which is intended to run out of
Qemu and could be run in any domain.
Although the Virtio block device is quite different from traditional
Xen PV block device (vbd) from the toolstack's point of view:
 - as the frontend is virtio-blk which is not a Xenbus driver, nothing
   written to Xenstore are fetched by the frontend currently ("vdev"
   is not passed to the frontend). But this might need to be revised
   in future, so frontend data might be written to Xenstore in order to
   support hotplugging virtio devices or passing the backend domain id
   on arch where the device-tree is not available.
 - the ring-ref/event-channel are not used for the backend<->frontend
   communication, the proposed IPC for Virtio is IOREQ/DM
it is still a "block device" and ought to be integrated in existing
"disk" handling. So, re-use (and adapt) "disk" parsing/configuration
logic to deal with Virtio devices as well.

For the immediate purpose and an ability to extend that support for
other use-cases in future (Qemu, virtio-pci, etc) perform the following
actions:
- Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
  that in the configuration
- Introduce new disk "specification" and "transport" fields to struct
  libxl_device_disk. Both are written to the Xenstore. The transport
  field is only used for the specification "virtio" and it assumes
  only "mmio" value for now.
- Introduce new "specification" option with "xen" communication
  protocol being default value.
- Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
  one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model

An example of domain configuration for Virtio disk:
disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']

Nothing has changed for default Xen disk configuration.

Please note, this patch is not enough for virtio-disk to work
on Xen (Arm), as for every Virtio device (including disk) we need
to allocate Virtio MMIO params (IRQ and memory region) and pass
them to the backend, also update Guest device-tree. The subsequent
patch will add these missing bits. For the current patch,
the default "irq" and "base" are just written to the Xenstore.
This is not an ideal splitting, but this way we avoid breaking
the bisectability.

Changes V4 -> V5:
   - split the changes, change the order of the patches
   - update patch description
   - don't introduce new "vdisk" configuration option with own parsing logic,
     re-use Xen PV block "disk" parsing/configuration logic for the virtio-disk

   - add LIBXL_HAVE_DEVICE_DISK_VIRTIO
   - update libxlu_disk_l.[ch]
   - drop num_disks variable/MAX_VIRTIO_DISKS

Changes V5 -> V6:
   - rebase on current staging
   - use "%"PRIu64 instead of %lu for disk->base in device_disk_add()
   - update *.gen.go files

Changes V6 -> V7:
   - rebase on current staging
   - update *.gen.go files and libxlu_disk_l.[ch] files
   - update patch description
   - rework significantly to support more flexible configuration
     and have more generic basic implementation for being able to extend
     that for other use-cases (virtio-pci, qemu, etc).

Changes V7 -> V8:
   - update *.gen.go files and libxlu_disk_l.[ch] files
   - update patch description and comments in the code
   - use "specification" config option instead of "protocol"

     in libxl_device_disk

Changes V8 -> V9:
   - update (and harden) checks in libxl__device_disk_setdefault(),
     return error in case of incorrect settings of specification
     and transport
   - remove both asserts in device_disk_add()
   - update virtio related code in libxl__disk_from_xenstore(),
     do not fail if specification node is absent, replace
     open-coded checks of fetched specification and transport by
     libxl_disk_specification_from_string() and libxl_disk_transport_from_string()
     respectively
   - s/libxl_device_disk_get_path/libxl__device_disk_get_path
   - add a comment for virtio-mmio parameters in struct libxl_device_disk

Changes V9 -> V10:
   - s/ERROR_FAIL/ERROR_INVAL in both places in libxl__device_disk_setdefault()

Changes V10 -> V10.1:
   - fix small coding style issue in libxl__device_disk_get_path()
   - drop specification check in main_blockattach() and add
     required check in libxl__device_disk_setdefault()
   - update specification check in main_blockdetach()

Changes V10.1 -> V11:
   - Anthony already gave his Reviewed-by, I dropped it due to the changes
   - George already gave his Acked-by, I dropped it due to the changes
   - s/other/standalone for the backendtype

Subject: [PATCH 02/16] libxl: Introduce basic virtio-mmio support on Arm
Date: Wed, 17 Aug 2022 10:06:47 +0800

From: Julien Grall <julien.grall@arm.com>

This patch introduces helpers to allocate Virtio MMIO params
(IRQ and memory region) and create specific device node in
the Guest device-tree with allocated params. In order to deal
with multiple Virtio devices, reserve corresponding ranges.
For now, we reserve 1MB for memory regions and 10 SPIs.

As these helpers should be used for every Virtio device attached
to the Guest, call them for Virtio disk(s).

Please note, with statically allocated Virtio IRQs there is
a risk of a clash with a physical IRQs of passthrough devices.
For the first version, it's fine, but we should consider allocating
the Virtio IRQs automatically. Thankfully, we know in advance which
IRQs will be used for passthrough to be able to choose non-clashed
ones.

Please note, this is a split/cleanup/hardening of Julien's PoC:
"Add support for Guest IO forwarding to a device emulator"

Changes RFC -> V1:
   - was squashed with:
     "[RFC PATCH V1 09/12] libxl: Handle virtio-mmio irq in more correct way"
     "[RFC PATCH V1 11/12] libxl: Insert "dma-coherent" property into virtio-mmio device node"
     "[RFC PATCH V1 12/12] libxl: Fix duplicate memory node in DT"
   - move VirtIO MMIO #define-s to xen/include/public/arch-arm.h

Changes V1 -> V2:
   - update the author of a patch

Changes V2 -> V3:
   - no changes

Changes V3 -> V4:
   - no changes

Changes V4 -> V5:
   - split the changes, change the order of the patches
   - drop an extra "virtio" configuration option
   - update patch description
   - use CONTAINER_OF instead of own implementation
   - reserve ranges for Virtio MMIO params and put them
     in correct location
   - create helpers to allocate Virtio MMIO params, add
     corresponding sanity-�hecks
   - add comment why MMIO size 0x200 is chosen
   - update debug print
   - drop Wei's T-b

Changes V5 -> V6:
   - rebase on current staging

Changes V6 -> V7:
   - rebase on current staging
   - add T-b and R-b tags
   - update according to the recent changes to
     "libxl: Add support for Virtio disk configuration"

Changes V7 -> V8:
   - drop T-b and R-b tags
   - make virtio_mmio_base/irq global variables to be local in
     libxl__arch_domain_prepare_config() and initialize them at
     the beginning of the function, then rework alloc_virtio_mmio_base/irq()
     to take a pointer to virtio_mmio_base/irq variables as an argument
   - update according to the recent changes to
     "libxl: Add support for Virtio disk configuration"

Changes V8 -> V9:
   - Stefano already gave his Reviewed-by, I dropped it due to the changes
   - remove the second set of parentheses for check in alloc_virtio_mmio_base()
   - clarify the updating of "nr_spis" right after num_disks loop in
     libxl__arch_domain_prepare_config() and add a comment on top of it
   - use GCSPRINTF() instead of using a buffer of a static size
     calculated by hand in make_virtio_mmio_node()

Changes V9 -> V10:
   - add Stefano's and Anthony's R-b

Jan, that makes sense. I will send a patch v2 to do so.

Subject: [PATCH v2] xen: x86: remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY
Date: Wed, 17 Aug 2022 06:43:33 +0200
Message-Id: <20220817044333.22310-1-lukas.bulwahn@gmail.com>
X-Mailer: git-send-email 2.17.1

Commit c70727a5bc18 ("xen: allow more than 512 GB of RAM for 64 bit
pv-domains") from July 2015 replaces the config XEN_MAX_DOMAIN_MEMORY with
a new config XEN_512GB, but misses to adjust arch/x86/configs/xen.config.
As XEN_512GB defaults to yes, there is no need to explicitly set any config
in xen.config.

Just remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY.

  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

  commit 66dd1c62b2a3c707bd5c55750d10a8223fbd577f
  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking

Hi all
 Sorry for that, please ignore this too.  I sent the wrong email.

> Subject: [PATCH 01/16] libxl: Add support for Virtio disk configuration
>=20
> From: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>
>=20
> This patch adds basic support for configuring and assisting virtio-mmio
> based virtio-disk backend (emulator) which is intended to run out of
> Qemu and could be run in any domain.
> Although the Virtio block device is quite different from traditional
> Xen PV block device (vbd) from the toolstack's point of view:
>  - as the frontend is virtio-blk which is not a Xenbus driver, nothing
>    written to Xenstore are fetched by the frontend currently ("vdev"
>    is not passed to the frontend). But this might need to be revised
>    in future, so frontend data might be written to Xenstore in order to
>    support hotplugging virtio devices or passing the backend domain id
>    on arch where the device-tree is not available.
>  - the ring-ref/event-channel are not used for the backend<->frontend
>    communication, the proposed IPC for Virtio is IOREQ/DM
> it is still a "block device" and ought to be integrated in existing
> "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
> logic to deal with Virtio devices as well.
>=20
> For the immediate purpose and an ability to extend that support for
> other use-cases in future (Qemu, virtio-pci, etc) perform the following
> actions:
> - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and
> reflect
>   that in the configuration
> - Introduce new disk "specification" and "transport" fields to struct
>   libxl_device_disk. Both are written to the Xenstore. The transport
>   field is only used for the specification "virtio" and it assumes
>   only "mmio" value for now.
> - Introduce new "specification" option with "xen" communication
>   protocol being default value.
> - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
>   one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
>=20
> An example of domain configuration for Virtio disk:
> disk =3D [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=3Dstandalone,
> specification=3Dvirtio']
>=20
> Nothing has changed for default Xen disk configuration.
>=20
> Please note, this patch is not enough for virtio-disk to work
> on Xen (Arm), as for every Virtio device (including disk) we need
> to allocate Virtio MMIO params (IRQ and memory region) and pass
> them to the backend, also update Guest device-tree. The subsequent
> patch will add these missing bits. For the current patch,
> the default "irq" and "base" are just written to the Xenstore.
> This is not an ideal splitting, but this way we avoid breaking
> the bisectability.

Just wondering - is this really worth panic()ing?

Again just wondering: Wouldn't it be an option to avoid the initial
page size alignment (and the resulting padding) here, simply making
.data.ro_after_init part of .rodata and do the earlier write-protection
only up to (but excluding) the page containing __ro_after_init_start?

The function should never fails and it sounds wrong to me to continue in 
the unlikely case it will fail.

So both this question and the previous one will impair the security of 
Xen on Arm (even though the later is only at boot time).

This is not something I will support just because we are going to save < 
PAGE_SIZE. If we are concern of the size wasted, then there are other 
way to mitigate it (i.e. moving more variables to __ro_after_init).

Cheers,

Subject: [XEN PATCH v2] build: Fix x86 out-of-tree build without EFI
Date: Wed, 17 Aug 2022 10:15:40 +0100
Message-ID: <20220817091540.18949-1-anthony.perard@citrix.com>

We can't have a source file with the same name that exist in both the
common code and in the arch specific code for efi/. This can lead to
comfusion in make and it can pick up the wrong source file. This issue
lead to a failure to build a pv-shim for x86 out-of-tree, as this is
one example of an x86 build using the efi/stub.c.

The issue is that in out-of-tree, make might find x86/efi/stub.c via
VPATH, but as the target needs to be rebuilt due to FORCE, make
actually avoid changing the source tree and rebuilt the target with
VPATH ignored, so $@ lead to the build tree where "stub.c" dosen't
exist yet so a link is made to "common/stub.c".

Rework the new common/stub.c file to have a different name than the
already existing one, by renaming the existing one. We will take
example of efi/boot.c and have the common stub.c include a per-arch
stub.h. This at least avoid the need to expose to Arm both alias
efi_compat_get_info and efi_compat_runtime_call.

Avoid using $(EFIOBJ-y) as an alias for $(clean-files), add
"stub.c" directly to $(clean-files).

Also update .gitignore as this was also missing from the original
patch.

Notes:
    v2:
    - instead of renaming common/efi/stub.c to common_stub.c; we rename
      arch/*/efi/stub.c to stub.h and include it from common/stub.c
    - update .gitignore

Doesn't this need to be !(memflags & MEMF_no_scrub)? And then -
with assignment having failed and with it being just a single page
we're talking about, the page was not exposed to the guest at any
point afaict. So I don't see the need for scrubbing in the first
place.

Also I think the rename of the function would better be done first,
since then you wouldn't need to touch this line again right in the
next patch, and the prepare/unprepare pairing would also be visible
right here. This would then also better fit with the introduction
of prepare_*() in the previous patch (which, afaic, the name
change could also be merged into; FTAOD I don't mind it to be
separate).

Almost - I don't see anything wrong with using ENTRY() without any END*()
for inner labels, if the implied alignment is wanted. If no alignment nor
type / size are wanted, we have GLOBAL(). And recall that I already did
post a patch adding various ENDPROC() (which could be converted to
ENDFUNC() if that name is indeed liked better, and which could easily
have ENDDATA() or some such added), see
https://lists.xen.org/archives/html/xen-devel/2022-04/msg00876.html .
With Andrew's odd reply I didn't see fit to post a v2 so far, where I'm
now having a further patch adding .hidden directives into GLOBAL() and
(indirectly) ENTRY(). Not the least because my reply (where I did already
indicate that Linux'es machinery looks a little too involved to me)
didn't have any further responses, which would at least have helped
clarify what - if anything - I had "rejected" long ago.

In the Linux kernel, the GIC driver tries to reserve ITS interrupt
table, and the reserved pages can survive for kexec/kdump and will be
used for secondary kernel.  Linux kernel relies on MEMRESERVE EFI
configuration table for memory page , but this table is not supported
by Xen.

This patch adds a MEMRESERVE configuration table into the system table,
it points to a dummy data structure acpi_table_memreserve, this
structure has the consistent definition with the Linux kernel.
Following the method in Xen, it creates a table entry for the structure
acpi_table_memreserve.

Subject: [PATCH v2] x86/entry: move .init.text section higher up in the code for readability
Date: Wed, 17 Aug 2022 14:03:45 +0100
Message-ID: <20220817130345.28669-1-jane.malalane@citrix.com>
X-Mailer: git-send-email 2.11.0
MIME-Version: 1.0
Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: 8bit

.init.text is a small section currently located amongst .text.entry
code. Move it above .text.entry.

This has no functional change but makes the code a bit more readable.

v2:
 * code style
 * replace incorrect .popsection with .section
 * add commit message

Please make sure you Cc all maintainers of all files that you touch.
Albeit, see below, you could indeed have avoided Cc-ing me if you
hadn't misplaced stuff in two of the headers that you fiddle with.

Nit: Indentation.

This is the 3rd magic "2" - I think there wants to be some consolidation,
such that it becomes obvious which "2"-s really are the same (and would
change together if, like you do here, another entry is needed).

Rather than adjusting offset and calculating efi_conf_table fdrom scratch,
perhaps better simply efi_conf_table++? That way there would be one less
cast, which are always somewhat risky.

This header holds ACPI spec defined data structures. This one looks
to be a Linux one, and hence shouldn't be defined here. You use it
in a single CU only, so I see no reason to define it there.

Furthermore - what if Linux decided to change their structure? Or
is there a guarantee that they won't? Generally such structures
belong in the public interface, guaranteeing forward compatibility
even if Linux decided to change / extend theirs (at which point
consuming code there would need to do translation, but maybe using
a Xen-defined struct [plus translation in Linux] right away would
be best).

Finally, style-wise, please don't use u64 in new code anymore; we
are trying hard to move over to standard uint<N>_t types. Plus,
unless indeed mandated by Linux, please avoid signed types for
fields (or variables) which can never go negative.

Please don't add double blank lines anywhere.

This header holds EFI spec mandated definitions (generally taken
from the gnu-efi project), when this one again looks to be a Linux
one (and again looks to be used in only a single CU).

No, there is not. The memreserve table is an internal interface
between the EFI stub loader and the Linux kernel proper.

As I have argued many times before, booting the arm64 kernel in
EFI/ACPI mode without going through the EFI stub violates the ACPI
spec, and relies on interfaces that were not intended for public
consumption.

There's an explanation in the commit message, quoted here:

The problem with `test -f $@` it doesn't test what we think it does. It
doesn't test for the presence of a regular file in the source tree as
stated in the original tree. First, `test -f` happily follow symlinks.
Second, $@ is always going to point to the build dir, as GNU Make will
try to not make changes to the source tree, if I understand the logic
correctly.

Instead of `test -f`, we could probably remove the "FORCE" from the
prerequisite, but there's still going to be an issue if there's a file
with the same name in both common and per-arch directory, when the common
file is newer.

So `test -f` needs to go.

Cheers,

I can rename and expand a bit further.

okay

On x86 it cannot be assumed that the domid for the initial domain is 
zero(0). See get_initial_domain_id() for which, afaict, is not a valid 
call under Arm.

Just to be pedantic, this really should just be labeled as "arm domain 
construction". As I discovered during all of this, Arm is always capable 
of building multiple domains at boot. The dom0less construct is really 
just a mode of the domain builder to never construct/start the initial 
domain (dom0) if the dom0less flag is set, regardless if there is one 
defined in the DTB.

A simplistic way to state it is, remove all assumptions/conventions 
about domain construction by the hypervisor. Instead, require explicit 
declarations about what domains the hypervisor should construct.

In the current HL series, there is no binding/enforcement/validation of 
the boot configuration and requirements of the enforcing XSM module. For 
the case when FLASK is the enforcing XSM module, the domain 
configuration may not have provided labels for the domains. In this case 
it would mean either FLASK refuses/fails the domain create check if a 
SID ref is not provided or a sensible policy/heuristic must be codified.

I agree it is not quite right, but more so that it is leveraging the 
assumption from the basic policy module (dummy policy) that only the 
initial domain (dom0) will have is_privileged set. As stated above, 
domid !=0 and is_privileged being set already exists for PV shim, not 
something being introduced by HL. HL only expands the possibility for 
the configuration to be built outside PV shim.

With that said, unless I am missing something, the heuristic below will 
enforce the singleton. While it is possible that 
flask_domain_alloc_security() would allocate a security context for more 
than one domain containing the label of dom0_t. The 
flask_domain_create() check will only allow the first domain with this 
label to be created, regardless if the domain create was initiated by 
the hypervisor or by a runtime toolstack.

Correct, this is why I pushed for the rules to be in the policy instead 
of in the code. If someone wants to use HL to do something custom, they 
can define their desired types, including dropping the dom0_t type, in 
policy and explicitly provided labels to domain in the boot configuration.

As mentioned above, d->domid == 0, is not a valid assumption even before 
the introduction of HL.

Correct, this makes a stronger/hard enforcement that only one domain can 
ever be labeled as dom0_t. As mentioned, previously it was only checked 
when the idle domain was doing the construction. Which made it possible 
to construct multiple domains labeled as dom0_t, as long as the policy 
was altered to allow a domain type to construction domains of type 
dom0_t. IMHO, if there is a desire to enable configurations with 
multiple all-privileged domains, then that configuration should define a 
different domain type and use HL to have the initial domain constructed 
with that type. The type dom0_t is special, mostly to align with 
historical expectations/conventions, and should not be repurposed by 
custom FLASK policies.

I disagree because "domid == 0" is not a valid check and IMHO the 
enforcement of dom0_t being a singleton should be as strong as possible.

I do not really like the empty header but I have no better solution so:
Reviewed-by: Bertrand Marquis <bertrand.marquis@arm.com>

Also I did some compilation runs and it works.

Hmm, yes, I had guessed that this might be it, but I wasn't able to make
the connection, sorry.

I didn't think it would to that. $@ is the target of the rule, and the
(pattern) target explicitly points into the build tree, by way of using
$(obj).

Which is of no relevance here, afaict.

This would be a mistake now, wouldn't it? I did add "(still)" in my earlier
reply for the very reason that it looks to me as if this change might have
been an attempt to address the issue without any renaming.

> So `test -f` needs to go.

I'm sorry to conclude that for now I continue to only see that its removal
does no harm (hence the "(or perhaps just wanted)" in my original reply),
but I still don't see that it's strictly needed. Therefore I'm okay with
the change as is, but I don't view the description as quite clear enough
in this one regard.

Don't you also need __aligned(PAGE_SIZE) here? (Strictly speaking
the type itself would need page alignment, but enforcing it just
for the variable is enough since we force suitable "post"-alignment
in the linker script. Provided, of course, that all other
contributions to the section also force the necessary alignment,
but I think we can take this for given - I do recall changing some
items several years ago, and a quick grep looks to confirm it.)

is_memory_hole was implemented for x86 and not for ARM when introduced.
Replace is_memory_hole call to pci_check_bar as function should check
if device BAR is in defined memory range. Also, add an implementation
for ARM which is required for PCI passthrough.

On x86, pci_check_bar will call is_memory_hole which will check if BAR
is not overlapping with any memory region defined in the memory map.

On ARM, pci_check_bar will go through the host bridge ranges and check
if the BAR is in the range of defined ranges.

Hmm, this suggests that Dom0 cannot use the controller without the Kconfig
enabled, which I hope is not the case. But I notice that patch 1, which
was committed already, still uses pci_ro_device() rather than
pci_hide_device() (like ehci-dbgp.c does).

I did comment on this last part before. There very minimum that I'd expect
to appear here is a comment as to the issue with other elements living on
the same page which a domain's driver may actually find a need to write to.
As said before - as soon as such a report would surface, we'd likely need
to add write emulation support for the leading/traling parts of the page(s)
that Xen doesn't use itself.

I think it would be best if the default value was "0"; I can see though
that "NONE" being zero also makse sense, if the enum was to be used in
boolean context (which afaics it currently isn't).

Nit: Blank line please between declaration(s) and statement(s).

Any reason you're using parse_bool() and not parse_boolean() here?
That would save you the open-coded strncmp() afaict.

Finally a remark seeing the opt_dbgp use here and the identically
named option in ehci-dbgp.c, taken together with your multiple-
serial-consoles patch: Since the two option consumers are now
different, they can't sensibly coexist anymore. There were issues
already before - it doesn't seem to be possible this way to run
EHCI and XHCI based consoles in parallel. (An exceptional case
would be if <integer> for both was intended to be same number.)
IOW I think one of the options needs renaming; it was a mistake of
mine to not have pointed this out before committing patch 1.
Following the name of the source file as well as e.g. the title
here - maybe "dbc="?

Doesn't this need to be s >= PFN_DOWN(addr)? Or else why is e checked
against PFN_UP()?

Just as a side note - I find such (the first instance here) uses of the
unary & operator odd. The same effect will be had without it. So all it
does (in my opinion) is make things harder to read (just very slightly,
of course).

Simply "return bar_data.is_valid;"?

Subject: [XEN PATCH] build: Fix missing MAKEFLAGS --no-print-directory

While we already have "--no-print-directory" added to the make flags
in some cases, there's one case where the flags is missing, when doing
an out-of-tree build with O=, e.g.
    cd xen; make O=build

Without it, we just have loads of "Entering directory" and "Leaving
directory" with the same directory.

The comment and location in the Makefile are copied from Linux.

It is the case, because you requested reset quirk to be behind
"experimental" tag in kconfig. This quirk is (currently) necessary even
if just dom0 uses the controller.
I'm happy to include the quirk by default, but I got impression you
wouldn't accept it. And I'd rather avoid marking the whole driver as
"experimental" (which hides it unless you select UNSUPPORTED) just
because of a small code necessary to share it with dom0.

I did included paragraph in the commit message:

Do you want this as a code comment too?

I can probably use parse_boolean() too, but then handling "hwdom"
variant would be a bit weird. I could skip 'share=3Dhwdom' parsing at all,
since that's default if the kconfig option is enabled, but I'm not sure
if that's a good idea.

Yes, I can rename the option here. That requires also registering new
SERHND_* and inventing new value for console=3D parameter (implemented in
serial_parse_handle()). "dbc" there too?

Hmm, well, I'm not happy about that quirk (and I did point out how it's
done for EHCI), but I agree we don't want to "hide" the entire drivers,
and I continue to think Dom0 should, by default, be able to use the
device (to the extent possible). So I guess I have no choice but to
accept the use of this quirk by default.

A shorter form thereof perhaps, but yes, absolutely. Getting at that
information shouldn't require locating the commit.

May I suggest that you take a look at xen/arch/x86/spec-ctrl.c's uses
of parse_boolean()? Maybe you consider some of those "weird" as well,
but it's not like these have been around forever and are now deemed
"bad".

Probably best to be halfway consistent with the naming, yes.

Hi Thorsten,

Actually, now I realize that was not the first report to lkml about this
issue, although it *was* the first report to the regressions mailing list.

Actually, the first report to lkml about this issue was Jan's patch that
will hopefully soon make it to linux-next and mainline. So the proper
Link: tag for this issue in the actual patch to be committed to the mainline
kernel is to Jan's patch that was originally posted to lkml before any
user reported it to the regressions mailing list. To know there was a
regression from Jan's original patch, one would need to have read his
commit message since he did not actually report it as a regression to the
regressions mailing list at that time, nor did he identify a culprit commit
at that time.

Bottom line: everything seems OK right now because the patch moving
towards mainline does have the correct Link: tag. Thanks for all the
work you have done on this regression.

Best regards,

Chuck

get_initial_domain_id() had slipped my mind.  I had thought a little
bit about the PV shim case in the past, and my guess is no one has
built a PV shim with Flask.  Running flask for a single domain under
the PV shim is a little silly.  If you did, the domain running under
PV shim would get dom0_t, but it is a domU - A little weird.

Oh, this is interesting:
    /* Create initial domain.  Not d0 for pvshim. */
    domid = get_initial_domain_id();
    d = domain_create(domid, &dom0_cfg, pv_shim ? 0 : CDF_privileged);

So the PV shim domain is not privileged, and get_initial_domain_id
will return != 0 for the pv-shim domain.  Your change would actually
assign it domU_t.

I think this means the domid == 0 check could still be used.   I guess
I'm approaching the problem by trying to restrict the assignment of
dom0_t as much as possible.  It's definitely needed for the
traditional dom0 case, but any other use seems suspect.

It's inconsistent to hand out dom0_t twice when it cannot be used
twice.  It does the right thing, so it's fine.  It just seems
inconsistent.

Anyway, if you really want to move forward with not using the domid, I
guess it's okay.

And after writing all that, dom0_t could be modified to not be non-singleton...

Jason

Subject: [PATCH] Use direct I/O for loop devices
Date: Wed, 17 Aug 2022 16:46:34 -0400
Message-Id: <20220817204634.1886-1-demi@invisiblethingslab.com>

This is a huge performance improvement for two reasons:

1. It uses the filesystem’s asynchronous I/O support, rather than using
   synchronous I/O.
2. It bypasses the page cache, removing a redundant layer of caching and
   associated overhead.

Subject: USB passthrough fails with 64GB drive but works fine with 8GB drive

Hi All

On XEN-4.16 with Ubuntu 22.04 Dom0 and HVM-DomU, I tried to do a USB mass
storage device passthrough to DomU.
I followed the PVUSB method mentioned in
https://wiki.xenproject.org/wiki/Xen_USB_Passthrough.

With 8GB sandisk pen drive, i am able to do USB passthrough to DomU.
But with 64GB sandisk pendrive, though able to mount/umount in Dom0, not
able to do passthrough to DomU.
I see IO errors in dmesg  when tried to access the usb disk folder in DomU.
Both 8GB and 64GB disks are 3.2Gen1. (Not tried with 16GB & 32GB drives).

Does anyone know why 64GB usb disk passthrough fails with the below error ?

Dmesg Error:

I guess you want to first check (maybe in tools/configure) that losetup
actually supports that option. The old-ish one I'm looking at doesn't,
according to its --help output at least.

Sorry for this.  When I send a new patch in next time, I will use
./scripts/get_maintainer.pl to find out the maintainers.

I will define a macro for the number of configuration table and add
comment for it.

Yeah, using "efi_conf_table++" is much better.  Will do.

Okay, I will define the structure in the arm specific file, e.g. I
move it to the file xen/arch/arm/acpi/domain_build.c.

I saw Ard has helped to answer this question in his email.  As Ard
said, the general way is to rely on Linux EFI stub to allocate the
data structure for MEMRESERVE configuration table.

Given Xen uses pseudo EFI booting (the ACPI table is passed via DT), in
short term I don't think Xen can support Linux EFI stub, so we need to
maintain this structure in Xen as well.

This structure eventually will not change frequently, so I assume
later we will have little effort for maintainence it.

Sure, will follow this and update the data structure.

I will move this macro into the file xen/arch/arm/efi/efi-dom0.c, so
far only Arm64 platform uses it.

"Will not change frequently" isn't enough. Imo there needs to be a
public interface structure in Xen and translation code in Linux.
That's the only way the consuming code in Linux can remain (largely)
independent of changes to the structure in Linux (i.e. changes there
can be expected to be accompanied by updating of this code, perhaps
simply in order to keep things building).

I agree that using Linux EFI stub will require more effort. I would also 
need to go through the mailing list archives (or maybe Stefano 
remember?) to understand why we decided against using the EFI stub.

I have looked at the commit message. IIUC, if this table is not created 
then Kexec will not work. Is there anything else that would not work?

IOW, would Linux be unusable if we don't create MEMRESERVE?

The problem is not really "maintainance" here. It is more that if Linux 
is updating the structure in a non-backward compatible way, then new
version of Linux would not boot on older Xen.

We would have similar probable with new Xen booting older Xen because 
the hypervisor doesn't know (and should not need to know) which OS is used.

In the nutshells, Xen should only use stable interface. If MEMRESERVE is 
really necessary then we should either switch to the Linux EFI stub or 
standardize MEMRESERVE.

Cheers,

Yeah, seems to me using the EFI stub is the right thing to do.

I read Xen code and found Xen doesn't provide boot time callback, this
is the main reason blocked me to move forward to that way.

No, AFAIK, kexec/kdump is the only customer to use the persistent
reserved memory in the Linux kernel.

I personally think this will pontentially impact other kernel
debugging modules, like ramoops, it also needs to use persistent
reserved memory when rebooting the kernel.  But now kernel code
doesn't add ramoops memory region into EFI MEMRESERVE table.

> IOW, would Linux be unusable if we don't create MEMRESERVE?

If we don't create EFI MEMRESERVE, kernel still can boot up
successfully, though it cannot add pages into the reserved memory
table and reports oops.

Without EFI MEMRESERVE, the reserved memory table cannot be passed from
the primary kernel to the secondary kernel, this is why it's important
for debugging tools.

Fair point.

Yeah, here I really need your (and other maintainers) opinions.  Seems
to me, support Linux EFI stub would be the best thing to do, to be
honest, this is a task which is out of my capability :)

Current approach in this patch is not perfect, it lets things to work.
So please let me know the conclusion from your side.

Thanks,
Leo

Yes, actually Xen doesn't care about the structure definition for
linux_efi_memreserve, it just allocates the table and finally used by
Linux kernel.  So another way is we can simply allocate a bigger
memory region (e.g. 64 bytes), which is sufficient than kernel's
structure linux_efi_memreserve size (only 16 bytes), then we can
initilize it as all zeros, and this can be helpful if later kernel
extend the data structure.

But this method is a bit arbitrary, this is why I did't write like this.
As Julien said, I think the critical thing is to make a call to support
EFI stub or not.  If rollback to use current method, then I am happy to
refine the patch with above idea.

Thanks,
Leo

Well, no, that's not how one would define a structure which can, in
a backwards compatible manner, be extended down the road.

I don't see how this can be a reasonable option - we'd have to re-
implement an almost complete EFI (to cover everything one can do
via boot or runtime services). But I'm not an Arm maintainer, so my
view here is at best advisory.

Let me ask a question but sorry it might be off topic.

In the Linux kernel function:

  static int gic_reserve_range(phys_addr_t addr, unsigned long size)
  {
          if (efi_enabled(EFI_CONFIG_TABLES))
                  return efi_mem_reserve_persistent(addr, size);
  
          return 0;
  }

We can see it will reserve persistent memory region for GIC pending
pages, so my question is if a platform is booting with DT binding
rather than ACPI table, how the primary kernel can reserve the pages
and pass the info to the secondary kernel?

Seems it's broken for kdump/kexec if kernel boots with using DT?

Thanks,
Leo

Hi Juergen,

Attached the qemu-dm-VM3.log .
No errors are reported here.
With 64GB drive  in DomU, both "lsusb" and "lsblk" commands   lists the USB
drive but dmesg shows I/O error.

Thanks
Sudheer

EFI supports both DT and ACPI boot, but only ACPI *requires* EFI.

So DT boot on hardware with affected GICv3 implementations works fine
with kdump/kexec as long as EFI is being used. Using non-EFI boot and
kexec on such systems will likely result in a splat on the second
kernel, unless there is another mechanism being used to reserve the
memory in DT as well.

Maybe we should wire up the EFI_PARAVIRT flag for Xen dom0 on arm64,
so that we can filter out the call above. That would mean that
Xen/arm64/dom0/kexec on affected hardware would result in a splat in
the second kernel as well, but whether that matters depends on your
support scope.

This is a false dichotomy. DT and UEFI are not exclusive, far from
it. That's actually how most non-ACPI systems boot these days, and
they are able to use kexec out of the box, using the EFI MEMRESERVE
internal API.

The real difference is between UEFI and non-UEFI. If you're allergic
to it, you have two options:

- you delegate the redistributor configuration to your bootloader,
  mark the corresponding memory as reserved in the DT from the
  bootloader, and you're done. A bunch of embedded systems do that,
  and are able to kexec.

- you keep configuring the RDs from Linux, but you must then mark the
  regions as reserved in the DT that is passed to the secondary
  kernel. It requires some cooperation from the kexec userspace to
  parse /proc/iomem and insert the correct annotations in that DT.

> Seems it's broken for kdump/kexec if kernel boots with using DT?

You equate kexec to kdump, which is wrong. kdump does *not* reuse the
memory from the previous kernel, and thus is immune to the RD table
reallocation problem. You don't need anything for kdump, as you will
use the RD tables as configured by the initial kernel.

In the context of Xen, dom0 doesn't have direct access to the host ITS 
because we are emulating it. So I think it doesn't matter for us because 
we can fix our implementation if it is affected.

That said, kexec-ing dom0 (or any other domain) on Xen on Arm would 
require some work to be supported. OOI, @leo is it something you are 
investigating?

Subject: [PATCH v5 1/9] xen/arm: smccc: add support for SMCCCv1.2 extended input/output registers
Date: Thu, 18 Aug 2022 12:55:53 +0200

SMCCC v1.2 [1] AArch64 allows x0-x17 to be used as both parameter
registers and result registers for the SMC and HVC instructions.

Arm Firmware Framework for Armv8-A specification makes use of x0-x7 as
parameter and result registers.

Let us add new interface to support this extended set of input/output
registers.

This is based on 3fdc0cb59d97 ("arm64: smccc: Add support for SMCCCv1.2
extended input/output registers") by Sudeep Holla from the Linux kernel

The SMCCC version reported to the VM is bumped to 1.2 in order to support
handling FF-A messages.

Subject: [PATCH v5 0/9] Xen FF-A mediator
Date: Thu, 18 Aug 2022 12:55:52 +0200
Message-Id: <20220818105601.1896082-1-jens.wiklander@linaro.org>
X-Mailer: git-send-email 2.31.1
MIME-Version: 1.0

Hi,

This patch sets add a FF-A [1] mediator modeled after the TEE mediator
already present in Xen. The FF-A mediator implements the subset of the FF-A
1.1 specification needed to communicate with OP-TEE using FF-A as transport
mechanism instead of SMC/HVC as with the TEE mediator. It allows a similar
design in OP-TEE as with the TEE mediator where OP-TEE presents one virtual
partition of itself to each guest in Xen.

The FF-A mediator is generic in the sense it has nothing OP-TEE specific
except that only the subset needed for OP-TEE is implemented so far. The
hooks needed to inform OP-TEE that a guest is created or destroyed is part
of the FF-A specification.

It should be possible to extend the FF-A mediator to implement a larger
portion of the FF-A 1.1 specification without breaking with the way OP-TEE
is communicated with here. So it should be possible to support any TEE or
Secure Partition using FF-A as transport with this mediator.

Thanks,
Jens

V4->v5:
* Added "xen/arm: move regpair_to_uint64() and uint64_to_regpair() to regs.h"
* Added documentation for the "ffa_enabled" guest config flag
* Changed to GPL license for xen/arch/arm/ffa.c
* Added __read_mostly and const where applicable
* Added more describing comments in the code
* Moved list of shared memory object ("ffa_mem_list") into the guest context
  as they are guest specific
* Simplified a few of the simple wrapper functions for SMC to SPMC
* Added a BUILD_BUG_ON(PAGE_SIZE != FFA_PAGE_SIZE) since the mediator
  currently depends on the page size to be same as FFA_PAGE_SIZE (4k).
* Added max number of shared memory object per guest and max number of
  size of each shared memory object
* Added helper macros to calculate offsets of different FF-A data structures
  in the communication buffer instead of relying on pointer arithmetic
* Addressed style issues and other comments
* Broke the commit "xen/arm: add FF-A mediator" into multiple parts, trying
  to add a few features at a time as requested
* Added a missing call to rxtx_unmap() in ffa_relinquish_resources()
* Assignment of "ffa_enabled" is kept as is until I have something definitive
  on the type etc.
* Tested with CONFIG_DEBUG=y

v3->v4:
* Missed v3 and sent a v4 instead by mistake.

v2->v3:
* Generates offsets into struct arm_smccc_1_2_regs with asm-offsets.c in
  order to avoid hard coded offsets in the assembly function
  arm_smccc_1_2_smc()
* Adds an entry in SUPPORT.md on the FF-A status
* Adds a configuration variable "ffa_enabled" to tell if FF-A should be
  enabled for a particular domu guest
* Moves the ffa_frag_list for fragmented memory share requests into
  struct ffa_ctx instead to keep it per guest in order to avoid mixups
  and simplify locking
* Adds a spinlock to struct ffa_ctx for per guest locking
* Addressing style issues and suggestions
* Uses FFA_FEATURES to check that all the needed features are available
  before initializing the mediator
* Rebased on staging as of 2022-06-20

v1->v2:
* Rebased on staging to resolve some merge conflicts as requested

Subject: [PATCH v5 3/9] xen/arm: add a primitive FF-A mediator
Date: Thu, 18 Aug 2022 12:55:55 +0200
Message-Id: <20220818105601.1896082-4-jens.wiklander@linaro.org>

Adds a FF-A version 1.1 [1] mediator to communicate with a Secure
Partition in secure world.

This commit brings in only the parts needed to negotiate FF-A version
number with guest and SPMC.

A guest configuration variable "ffa_enabled" is used to indicate if a guest
is trusted to use FF-A.

This is loosely based on the TEE mediator framework and the OP-TEE
mediator.

Subject: [PATCH v5 6/9] xen/arm: ffa: send guest events to Secure Partitions
Date: Thu, 18 Aug 2022 12:55:58 +0200
Message-Id: <20220818105601.1896082-7-jens.wiklander@linaro.org>
X-Mailer: git-send-email 2.31.1
In-Reply-To: <20220818105601.1896082-1-jens.wiklander@linaro.org>
References: <20220818105601.1896082-1-jens.wiklander@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The FF-A specification defines framework messages sent as direct
requests when certain events occurs. For instance when a VM (guest) is
created or destroyed. Only SPs which have subscribed to these events
will receive them. An SP can subscribe to these messages in its
partition properties.

The partition properties of each SP is retrieved with
FFA_PARTITION_INFO_GET which returns the information in our RX buffer.
Using FFA_PARTITION_INFO_GET changes the owner of the RX buffer to the
caller (us), so once we're done with the buffer it must be released
using FFA_RX_RELEASE before another call can be made.

Subject: [PATCH v5 7/9] xen/arm: ffa: support mapping guest RX/TX buffers
Date: Thu, 18 Aug 2022 12:55:59 +0200
Message-Id: <20220818105601.1896082-8-jens.wiklander@linaro.org>
X-Mailer: git-send-email 2.31.1
In-Reply-To: <20220818105601.1896082-1-jens.wiklander@linaro.org>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Adds support in the mediator to map and unmap the RX and TX buffers
provided by the guest using the two FF-A functions FFA_RXTX_MAP and
FFA_RXTX_UNMAP.

These buffer are later used to to transmit data that cannot be passed in
registers only.

Date: Thu, 18 Aug 2022 12:56:00 +0200

X-Mailer: git-send-email 2.31.1
In-Reply-To: <20220818105601.1896082-1-jens.wiklander@linaro.org>
References: <20220818105601.1896082-1-jens.wiklander@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Adds support in the mediator to handle FFA_PARTITION_INFO_GET requests
from a guest. The requests are forwarded to the SPMC and the response is
translated according to the FF-A version in use by the guest.

Using FFA_PARTITION_INFO_GET changes the owner of the RX buffer to the
caller (the guest in this case), so once it is done with the buffer it
must be released using FFA_RX_RELEASE before another call can be made.

Subject: [PATCH v5 9/9] xen/arm: ffa: support sharing memory
Date: Thu, 18 Aug 2022 12:56:01 +0200
Message-Id: <20220818105601.1896082-10-jens.wiklander@linaro.org>
X-Mailer: git-send-email 2.31.1
In-Reply-To: <20220818105601.1896082-1-jens.wiklander@linaro.org>
References: <20220818105601.1896082-1-jens.wiklander@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Adds support for a guest to share memory with an SP using FFA_MEM_SHARE,
FFA_MEM_RECLAIM and FFA_MEM_FRAG_TX. Small memory regions can be shared
using FFA_MEM_SHARE, but larger memory regions may need to be
transmitted in fragments with FFA_MEM_FRAG_TX. A memory region that
doesn't need to be shared any longer can be reclaimed with
FFA_MEM_RECLAIM once the SP doesn't use it any longer. This is checked
by the SPMC and not in control of the mediator.

With this commit we have a FF-A version 1.1 [1] mediator able to
communicate with a Secure Partition in secure world. The secure world
must use FF-A version 1.1, but the guest is free to use version 1.0 or
version 1.1.

The implementation is the bare minimum to be able to communicate with
OP-TEE running as an SPMC at S-EL1.

New changes have appeared in the meantime, in particular one partly undoing
what we still haven't merged (patch 1 here).

1: add 'preferred_cstates' module argument
2: add core C6 optimization for SPR
3: add AlderLake support
4: disable IBRS during long idle
5: make SPR C1 and C1E be independent

From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

On Sapphire Rapids Xeon (SPR) the C1 and C1E states are basically mutually
exclusive - only one of them can be enabled. By default, 'intel_idle' driver
enables C1 and disables C1E. However, some users prefer to use C1E instead of
C1, because it saves more energy.

This patch adds a new module parameter ('preferred_cstates') for enabling C1E
and disabling C1. Here is the idea behind it.

1. This option has effect only for "mutually exclusive" C-states like C1 and
   C1E on SPR.
2. It does not have any effect on independent C-states, which do not require
   other C-states to be disabled (most states on most platforms as of today).
3. For mutually exclusive C-states, the 'intel_idle' driver always has a
   reasonable default, such as enabling C1 on SPR by default. On other
   platforms, the default may be different.
4. Users can override the default using the 'preferred_cstates' parameter.
5. The parameter accepts the preferred C-states bit-mask, similarly to the
   existing 'states_off' parameter.
6. This parameter is not limited to C1/C1E, and leaves room for supporting
   other mutually exclusive C-states, if they come in the future.

Today 'intel_idle' can only be compiled-in, which means that on SPR, in order
to disable C1 and enable C1E, users should boot with the following kernel
argument: intel_idle.preferred_cstates=4

Enable C1E (if requested) not only on the BSP's socket / package. Alter
command line option to fit our model, and extend it to also accept
string form arguments.

v2: Also accept string form arguments for command line option. Restore
    C1E-control related enum from Linux, despite our somewhat different
    use (and bigger code churn).

From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

Add a Sapphire Rapids Xeon C6 optimization, similar to what we have for Sky Lake
Xeon: if package C6 is disabled, adjust C6 exit latency and target residency to
match core C6 values, instead of using the default package C6 values.

Make sure a contradictory "preferred-cstates" wouldn't cause bypassing
of the added logic.

From: Zhang Rui <rui.zhang@intel.com>

Similar to SPR, the C1 and C1E states on ADL are mutually exclusive.
Only one of them can be enabled at a time.

But contrast to SPR, which usually has a strong latency requirement
as a Xeon processor, C1E is preferred on ADL for better energy
efficiency.

Add custom C-state tables for ADL with both C1 and C1E, and

 1. Enable the "C1E promotion" bit in MSR_IA32_POWER_CTL and mark C1
    with the CPUIDLE_FLAG_UNUSABLE flag, so C1 is not available by
    default.

 2. Add support for the "preferred_cstates" module parameter, so that
    users can choose to use C1 instead of C1E by booting with
    "intel_idle.preferred_cstates=2".

Separate custom C-state tables are introduced for the ADL mobile and
desktop processors, because of the exit latency differences between
these two variants, especially with respect to PC10.

From: Peter Zijlstra <peterz@infradead.org>

Having IBRS enabled while the SMT sibling is idle unnecessarily slows
down the running sibling. OTOH, disabling IBRS around idle takes two
MSR writes, which will increase the idle latency.

Therefore, only disable IBRS around deeper idle states. Shallow idle
states are bounded by the tick in duration, since NOHZ is not allowed
for them by virtue of their short target residency.

Only do this for mwait-driven idle, since that keeps interrupts disabled
across idle, which makes disabling IBRS vs IRQ-entry a non-issue.

Note: C6 is a random threshold, most importantly C1 probably shouldn't
disable IBRS, benchmarking needed.

strictly speaking patches 3-5 are late submissions. Patch 5, however,
actually corrects patch 1, and I'd prefer to keep things in the order
in which they were put in for Linux. Whether we actually want patch 4
is to be determined; if not that one should be easy to leave out. In
any event I'd like to ask for you to consider granting an exception
on these last three patches.

Thanks, Jan

From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

This patch partially reverts the changes made by the following commit:

da0e58c038e6 intel_idle: add 'preferred_cstates' module argument

As that commit describes, on early Sapphire Rapids Xeon platforms the C1 and
C1E states were mutually exclusive, so that users could only have either C1 and
C6, or C1E and C6.

However, Intel firmware engineers managed to remove this limitation and make C1
and C1E to be completely independent, just like on previous Xeon platforms.

Therefore, this patch:
 * Removes commentary describing the old, and now non-existing SPR C1E
   limitation.
 * Marks SPR C1E as available by default.
 * Removes the 'preferred_cstates' parameter handling for SPR. Both C1 and
   C1E will be available regardless of 'preferred_cstates' value.

We expect that all SPR systems are shipping with new firmware, which includes
the C1/C1E improvement.

I think the problem was that EFI also includes some functions and to have a=
 proper EFI stub we would need to support those (console, mapping, disk acc=
ess).
Maybe this is something we could discuss but that would require to have som=
e kind of binary providing those services that we put in EL1 or at least a =
stub calling Xen for those functions.
One other solution of course is to run uboot and boot linux from this.

No it works perfectly fine.
There are some warnings and as pointed out later kexec is not useable (but =
is not supported anyway).

As we do support kexec on arm right now I think the current status should b=
e kept.
Those questions would need answering if we support kexec one day.

With this patch, you add something so that you could call SMCCCv1.2 but in =

I do not think this patch should bump the version we present to guests.

The comment here should be fixed, you are clobbering x19 hence you need to =

You do not need to save args (and no code is restoring it).

As said for the commit message, I do not see what changes are making Xen pr=

Three of the four reported issues a pretty clear how to take care
of, which is done in this series. The 4th, CID 1509375, isn't as
obvious, mainly because I don't know enough about Coverity to be
able to tell whether adding a cast there might help; the issue
reported for xenbaked suggests it wouldn't. The alternative I can
see would be an arch-independent piece of inline assembly, hiding
the transformation from time_t to int from the analysis tool. But
I'm not convinced such would be liked. Nor am I sure the can be
fully arch-ignorant, as time_t potentially being a 64-bit type
might not be possible to match with an "r" constraint on all 32-
bit architectures. So maybe what's left is memcpy() from a
"time_t" variable to an "int" one ...

1: xenbaked: properly use time_t in dump_stats()
2: console/client: properly use time_t in get_pty_fd()
3: libxl: use time_t for qmp_synchronous_send()'s last parameter

"int" is not a suitable type to hold / receive "time_t" values.

While it seems odd to have this simple a patch sit un-acked for this long,
it looks like I'm not the only one uncomfortable ack-ing it without knowing
why the entry was there. Old .hgignore history only tells me that at some
point build* was changed to build-*. This recent mail from Andrew
(https://lists.xen.org/archives/html/xen-devel/2022-08/msg01043.html)
matches my vague recollection of build-* being used as sub-trees for
building stuff when out-of-tree builds are possible, yet people also don't
want to build in an entirely separate tree.

Hence as a compromise between keeping the status quo and deleting the
entry, could we go with changing it to build-*/ ?

IMHO, this is better to add it here rather than in a FFA specific patch. 
Otherwise, one could raise the question of why we are adding wrapper 
when they are not used?

The comment is correct. x19 is one of the few registers that will not be 
clobbered by the SMC call. But we still need a register below to store 
'args', so we need to free it (what you call clobber).

The next instruction will overwrite x0. So if you don't save 'x0' to 
'x19' then you will not be able to load the rest of the registers.

AFAIU, this would mean an extra instruction to increment sp by 8 
(covering the xzr register).

Ack. I will modify as if ( (s < e) && (s >=3D PFN_DOWN(addr)) && (e <=3D PF=

commit 6c987150cf71976b5dd16b5f736dd5b0c6f6aee8
Author: Jan Beulich <jbeulich@suse.com>
Date:   Thu Aug 18 09:30:41 2022 +0200

    x86: rework hypercall argument count table instantiation & use
    
    The initial observation were duplicate symbols that our checking warns
    about. Instead of merely renaming one or both pair(s) of symbols,
    reduce #ifdef-ary at the same time by moving the instantiation of the
    arrays into a macro. While doing the conversion also stop open-coding
    array_access_nospec().

    x86/entry: move .init.text section higher up in the code for readability
    
    .init.text is a small section currently located amongst .text.entry
    code. Move it above .text.entry.
    
    This has no functional change but makes the code a bit more readable.

    x86/P2M: allow 2M superpage use for shadowed guests
    
    For guests in shadow mode the P2M table gets used only by software. The
    only place where it matters whether superpages in the P2M can be dealt
    with is sh_unshadow_for_p2m_change(): The table is never made accessible
    to hardware for address translation, and the only checks of _PAGE_PSE in
    P2M entries in shadow code are in this function (all others are against
    guest page table entries). That function has been capable of handling
    them even before commit 0ca1669871f8a ("P2M: check whether hap mode is
    enabled before using 2mb pages") disabled 2M use in this case for
    dubious reasons ("potential errors when hap is disabled").
    
    While doing this, move "order" into more narrow scope and replace the
    local variable "d" by a new "hap" one.

    x86/shadow: slightly consolidate sh_unshadow_for_p2m_change() (part III)
    
    In preparation for reactivating the presently dead 2M page path of the
    function, also deal with the case of replacing an L1 page table all in
    one go. Note that the prior comparing of MFNs to bypass the removal of
    shadows was insufficient (but kind of benign, for being dead code so
    far) - at the very least the R/W bit also needs considering there (to be
    on the safe side, compare the full [virtual] PTEs).
    
    While adjusting the first conditional in the loop for the use of the new
    local variable "nflags", also drop mfn_valid(): If anything we'd need to
    compare against INVALID_MFN, but that won't come out of l1e_get_mfn().

    x86/shadow: slightly consolidate sh_unshadow_for_p2m_change() (part II)
    
    Pull common checks out of the switch(). This includes extending a
    _PAGE_PRESENT check to L1 as well, which presumably was deemed redundant
    with p2m_is_valid() || p2m_is_grant(), but I think we are better off
    being explicit in all cases. Note that for L2 (or higher) the grant
    check isn't strictly necessary, as grants are only ever single pages.
    Leave a respective assertion.
    
    With _PAGE_PRESENT checked uniformly, the suspicious mfn_valid(omfn)
    checks can be dropped rather than moved/folded - if anything we'd need
    to compare against INVALID_MFN, but that won't come out of l1e_get_mfn().
    
    For L1 replace the moved out condition with a PTE comparison: There's
    no need for any update or flushing when the two match.

    x86/shadow: slightly consolidate sh_unshadow_for_p2m_change() (part I)
    
    Replace a p2m_is_ram() check in the 2M case by an explicit _PAGE_PRESENT
    one, to make more obvious that the subsequent l1e_get_mfn() actually
    retrieves something that really is an MFN. It doesn't really matter
    whether it's RAM, as the subsequent comparison with the original MFN is
    going to lead to zapping of everything except the "same MFN again" case.

    tools/libxl: Replace deprecated -soundhw on QEMU command line
    
    -soundhw is deprecated since 825ff02911c9 ("audio: add soundhw
    deprecation notice"), QEMU v5.1, and is been remove for upcoming v7.1
    by 039a68373c45 ("introduce -audio as a replacement for -soundhw").
    
    Instead we can just add the sound card with "-device", for most option
    that "-soundhw" could handle. "-device" is an option that existed
    before QEMU 1.0, and could already be used to add audio hardware.
    
    The list of possible option for libxl's "soundhw" is taken the list
    from QEMU 7.0.
    
    The list of options for "soundhw" are listed in order of preference in
    the manual. The first three (hda, ac97, es1370) are PCI devices and
    easy to test on Linux, and the last four are ISA devices which doesn't
    seems to work out of the box on linux.
    
    The sound card 'pcspk' isn't listed even if it used to be accepted by
    '-soundhw' because QEMU crash when trying to add it to a Xen domain.
    Also, it wouldn't work with "-device" might need to be "-machine
    pcspk-audiodev=default" instead.

Now I am working on automative reference platform; the first thing for
me is to resolve the kernel oops.

For long term, I think the kexec/kdump would be important to be
supported, to be clear, so far supporting kexec/kdump for Xen/Linux is
not priority for my work.

Also thanks a lot for Ard and Mark's replying. To be honest, I missed
many prerequisites (e.g. redistributor configurations for GIC in
hypervisor) and seems Xen uses a different way by emulating GICv3
controller for guest OS.  So now I am bit puzzle what's for next step
or just keep as it is?

Thanks,
Leo

I'd rather drop the function all together instead, it doesn't get much
use these days as it's been replaced in many cases.

On the other hand, there seems to be only one call site, it would
be only one extra change to drop it, so that would be one way to fix
this. As you wish.

If i understand Julien's remark correctly, the dom0 GICv3 is emulated,
and so it should not suffer from the issue that we are working around
here.

Given that this workaround is still the sole user of the MEMRESERVE
API, we would like to remain free to rip it out and replace it
completely if we need to, and so implementing it in Xen is a bad idea,
especially if the issue in question does not even exist in your case.
This means that even if you do decide to support kexec, things should
work fine in spite of this warning regarding the failure to perform
the memory reservation, as the GIC can simply be reconfigured.

So perhaps we should just [conditionally] tone down the warning?

dump_stats() seems to be only used once, so it's probably fine.

Did you want to write "%.0f" or even "%.f" instead of "%0f"? It seems
that the '0' here mean '0'-padded, but without field width there would
be nothing to pad. I'm guessing you would want printf to write something
like "266 seconds" instead of "266.646168 seconds". Am I missing
something ?

I would be fine with that.

AFAIU, the two aliases are using by the compat code. So how about 
protecting it with CONFIG_COMPAT (like we do for other compat code in 
common code)?

So I agree with Anthony here. I think the approach we use for 
boot.c/efi-boot.h should not be promoted.

I also agree that "common-stub.c" sounds weird. But it would require 
some change in the build system (I always find a bit string we are using 
linking) which is likely too late for 4.17.

So I would be fine with stub-common.c and then protect the alias with 
#ifdef CONFIG_COMPAT.

Hey, I see the patch hit linux-next and regzbot noticed and
now lists the patch as an incoming fix. Great job with regzbot!

By the way, I think regzbot is a great idea, and I think any resources
devoted to develop it more would pay handsome returns for the
quality of Linux. If no one but you is working on it, I actually might
be willing to volunteer some time to help you develop it.

Best regards,

Chuck

Subject: [PATCH v2 0/3] introduce SPDX
Message-ID: <alpine.DEB.2.22.394.2208181453530.3790@ubuntu-linux-20-04-desktop>
User-Agent: Alpine 2.22 (DEB 394 2020-01-19)
MIME-Version: 1.0
Content-Type: text/plain; charset=US-ASCII

Hi all,

This small series introduces SPDX tags to Xen:

1) add a mention to SPDX in CODING_STYLE
2) add a LICENSES directory with licenses and SPDX tags
3) adds the SPDX single-line comment to arch/arm/*.c

Note that arch/arm/*.c is just a start. Also, to make the changes as
mechanical as possible I restricted myself to:
- adding the single-line comment at the top of the file
- removing the copyright lines (when present) from the top of the file
  header

I purposedly restrained myself to do other cleanups to the headers: this
series already touches many files and I prefer to keep these changes as
mechanical as possible. Further improvements (style improvement,
removing what's left of the header, removing copyright lines, etc.) can
be done with subsequent patches more easily.

License changes are not intentional.

Cheers,

Stefano

+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Version 2, June 1991
+
+Copyright (C) 1991 Free Software Foundation, Inc.
+51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is numbered 2
+because it goes with version 2 of the ordinary GPL.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Library General Public License, applies to some specially
+designated Free Software Foundation software, and to any other libraries
+whose authors decide to use it. You can use it for your libraries, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you
+distribute copies of the library, or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link a program with the library, you must provide complete object files to
+the recipients so that they can relink them with the library, after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+Our method of protecting your rights has two steps: (1) copyright the
+library, and (2) offer you this license which gives you legal permission to
+copy, distribute and/or modify the library.
+
+Also, for each distributor's protection, we want to make certain that
+everyone understands that there is no warranty for this free library. If
+the library is modified by someone else and passed on, we want its
+recipients to know that what they have is not the original version, so that
+any problems introduced by others will not reflect on the original authors'
+reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that companies distributing free software will
+individually obtain patent licenses, thus in effect transforming the
+program into proprietary software. To prevent this, we have made it clear
+that any patent must be licensed for everyone's free use or not licensed at
+all.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License, which was designed for utility programs. This
+license, the GNU Library General Public License, applies to certain
+designated libraries. This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it. Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program. However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+Because of this blurred distinction, using the ordinary General Public
+License for libraries did not effectively promote software sharing, because
+most developers did not use the libraries. We concluded that weaker
+conditions might promote sharing better.
+
+However, unrestricted linking of non-free programs would deprive the users
+of those programs of all benefit from the free status of the libraries
+themselves. This Library General Public License is intended to permit
+developers of non-free programs to use free libraries, while preserving
+your freedom as a user of such programs to change the free libraries that
+are incorporated in them. (We have not seen how to achieve this as regards
+changes in header files, but we have achieved it as regards changes in the
+actual functions of the Library.) The hope is that this will lead to faster
+development of free libraries.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, while the latter only works together with the
+library.
+
+Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library which contains a
+   notice placed by the copyright holder or other authorized party saying
+   it may be distributed under the terms of this Library General Public
+   License (also called "this License"). Each licensee is addressed as
+   "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+   Activities other than copying, distribution and modification are not
+   covered by this License; they are outside its scope. The act of running
+   a program using the Library is not restricted, and output from such a
+   program is covered only if its contents constitute a work based on the
+   Library (independent of the use of the Library in a tool for writing
+   it). Whether that is true depends on what the Library does and what the
+   program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+   purpose that is entirely well-defined independent of the
+   application. Therefore, Subsection 2d requires that any
+   application-supplied function or table used by this function must be
+   optional: if the application does not supply it, the square root
+   function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also compile or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   c) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   d) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the source code
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties to this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Library General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Library General Public License as published by
+the Free Software Foundation; either version 2 of the License, or (at your
+option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Library General Public
+License for more details.
+
+You should have received a copy of the GNU Library General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in
+the library `Frob' (a library for tweaking knobs) written

+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by
+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in
+the library `Frob' (a library for tweaking knobs) written
+by James Random Hacker.
+
+signature of Ty Coon, 1 April 1990

Subject: [PATCH] xen: move from strlcpy with unused retval to strscpy
Date: Thu, 18 Aug 2022 23:01:22 +0200

Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

We already have a copy of the licenses in COPYING/CONTRIBUTING. I don't 
particularly mind where you want to keep the licenses but I don't want 
them duplicated.

A user reading CODING_STYLE and CONTRIBUTING may think they need to also 
add the full license (see the section "COMMON COPYRIGHT NOTICES").

So as we are going to promote SPDX, we should update CONTRIBUTING to 
reflect that the full license should not be present copied.

Note that while the original Linux code has the same issue, I don't
really fancy sending there a patch similar to patch 1. That's because
my XSA-307 related "make find_next_{,zero_}bit() have well defined
behavior" was entirely ignored, so I would expect nothing better here.

1: correct string.h functions for "int" -> "unsigned char" conversion
2: tidy the memset() macro

Really I happened to be looking at the memset() macro, being a little
surprised of the special casing of 0 there. As a result I was curious to
see how much more efficient __memzero() really was compared to memset().
The first thing which actually caught my attention is that part of
__memzero()'s code lives outside of the function (i.e. ahead of
ENTRY()). This saves a branch (and interestingly memset() does _not_ do
the same), but (a) renders the ELF symbol table somewhat wrong and (b)
leaves debug info generated with gas 2.39 not covering the entire
function in the new subprogram DIE that it generates (line number info
and .debug_ranges are correct nevertheless).

While Arm64 does so uniformly, for Arm32 only strchr() currently handles
this properly. Add the necessary conversion also to strrchr(), memchr(),
and memset().

As to the placement in memset(): Putting the new insn at the beginning
of the function could perhaps be deemed more "obvious", but the code
reachable without ever making it to the "1" label only ever does byte
stores.

I wonder whether "if ( n_ )" is really helpful: It's extra code in all
callers passing a non-constant size, just to cover a pretty rare case
which memset() is required to deal with correctly anyway, and which
__memzero() also handles quite fine from all I can tell.

Hi Stefano,

There are some of the files below that didn't have copyright. It would 
be worth explaining in the commit message which license you selected and 
how. AFAICT you assumed they were GPLv2 but I am not sure this is 
correct at least one of them.

This license is not part of LICENSES. Was it intended?

If yes, this should be mentioned in one of the commit message (possible 
patch #2) and maybe in CONTRIBUTING (to tell user to not use it for new 
files) because one could expect all the LICENSES to be listed.

AFAIU, the assumption is all the files with no copyright are GPLv2. That 
works here. But ...

.... this file was split from mm.c which is gpl-2.0-or-later. So I don't 
think we can use GPL-2.0 here.

Your view here if we will never re-sync the code. This is incorrect, we 
still want to keep it close so we can benefit from improvement in the 
Linux code. So if you start tweaking the code just for coding style 
purpose, it will just make it more difficult for us (I appreciate this 
is limited here).

In this case, Linux has removed __memzero() is patch ff5fdafc9e97 "ARM: 
8745/1: get rid of __memzero()" because the performance difference with 
memset() was limited. For Xen, I think we should also remove the function.

With that, this patch becomes pointless.

Hi Jan,

So the assumption here is the rest of the code will always use byte 
stores. Given that this issue has been present for a long time, I think 
it would be wiser to do the conversion at the start of the function.

The changes in memchr() and strrchr() looks fine to me.

Hmm, I can't spot it on
https://patchwork.kernel.org/project/linux-arm-kernel/list/ , but
then again there are only very few entries there anyway which pre-
date July 2022. I've been able to easily spot it at

Subject: [PATCH v2 1/7] xen/evtchn: Make sure all buckets below d->valid_evtchns are allocated
Date: Fri, 19 Aug 2022 11:02:38 +0100
Message-Id: <710e9e6477270212136d6f2047fd15a033fa7d71.1660902588.git.rahul.singh@arm.com>

From: Julien Grall <jgrall@amazon.com>

Since commit 01280dc19cf3 "evtchn: simplify port_is_valid()", the event
channels code assumes that all the buckets below d->valid_evtchns are
always allocated.

This assumption hold in most of the situation because a guest is not
allowed to chose the port. Instead, it will be the first free from port
0.

When using Guest Transparent Migration and LiveUpdate, we will only
preserve ports that are currently in use. As a guest can open/close
event channels, this means the ports may be sparse.

The existing implementation of evtchn_allocate_port() is not able to
deal with such situation and will end up to override bucket or/and leave
some bucket unallocated. The latter will result to a droplet crash if
the event channel belongs to an unallocated bucket.

This can be solved by making sure that all the buckets below
d->valid_evtchns are allocated. There should be no impact for most of
the situation but LM/LU as only one bucket would be allocated. For
LM/LU, we may end up to allocate multiple buckets if ports in use are
sparse.

A potential alternative is to check that the bucket is valid in
is_port_valid(). This should still possible to do it without taking
per-domain lock but will result a couple more of memory access.

In a follow-up patch we will be able to either reserve or allocate a
port for various event channel helpers.

A new wrapper is introduced to either reserved a given port or allocate
an empty one if zero.

Take the opportunity to replace the open-coded version in
evtchn_bind_virq().

Subject: [PATCH v2 4/7] xen/evtchn: modify evtchn_bind_interdomain to support static evtchn
Date: Fri, 19 Aug 2022 11:02:41 +0100
Message-Id: <abe4c5be55125eb3da33dbd187fd9b8ad5ace714.1660902588.git.rahul.singh@arm.com>
X-Mailer: git-send-email 2.25.1
In-Reply-To: <cover.1660902588.git.rahul.singh@arm.com>
References: <cover.1660902588.git.rahul.singh@arm.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Static event channel support will be added for dom0less domains. Modify
evtchn_bind_interdomain to support static evtchn.

It is necessary to have access to the evtchn_bind_interdomain function
to do that, so make evtchn_bind_interdomain global and also make it
__must_check.

evtchn_bind_interdomain() always allocates the next available local
port. Static event channel support for dom0less domains requires
allocating a specified port. Modify the evtchn_bind_interdomain to
accept the port number as an argument and allocate the specified port
if available. If the port number argument is zero, the next available
port will be allocated.

evtchn_bind_interdomain() finds the local domain from "current->domain"
pointer. evtchn_bind_interdomain() will be called from the XEN to create
static event channel during domain creation. "current" pointer is not
valid at that time, therefore modify the evtchn_bind_interdomain() to
pass domain as an argument.

evtchn_alloc_unbound() always allocates the next available port. Static
event channel support for dom0less domains requires allocating a
specified port.

Modify the evtchn_alloc_unbound() to accept the port number as an
argument and allocate the specified port if available. If the port
number argument is zero, the next available port will be allocated.

Subject: [PATCH v2 6/7] xen: introduce xen-evtchn dom0less property
Date: Fri, 19 Aug 2022 11:02:43 +0100
Message-Id: <02993cf398573adf9e9bad62aa8d6e753b2c6ab9.1660902588.git.rahul.singh@arm.com>

Introduce a new sub-node under /chosen node to establish static event
channel communication between domains on dom0less systems.

An event channel will be created beforehand to allow the domains to
send notifications to each other.

Subject: [PATCH v2 7/7] xen/arm: introduce new xen,enhanced property value
Date: Fri, 19 Aug 2022 11:02:44 +0100

Content-Transfer-Encoding: 8bit

Introduce a new "xen,enhanced" dom0less property value "evtchn" to
enable/disable event-channel interfaces for dom0less guests.

The configurable option is for domUs only. For dom0 we always set the
corresponding property in the Xen code to true.

The problem is that there is no way to distinguish a system that
suffers from GICR LPI tables being immutable from one that allows the
LPI configuration being changed (either because the HW allows it or
because the hypervisor plays other games).

Once you're in the secondary kernel with the RDs enabled, you have
already lost if there is a chance you could have reused this memory,
and that's irrespective of being a guest or bare metal (interrupt
delivery should still work during kexec).

What we could do instead is to have some form of kexec hook that tries
to go and turn the RDs off before jumping into the secondary kernel.
If the hypervisor allows this (and honours the GICR_CTLR.EnableLPI
bit), then there won't be any screaming in the secondary kernel.

This is probably a new infrastructure though, as I don't think we have
anything of the sort at the moment.

Hi Elena, Tim, Jan, Andrew, Roger, George,

Elena, could you give a ack or review this patch, for the change in
"tools/debugger/gdbsx/Rules.mk" ?

Tim, could you give a ack or review this patch, for the change in
"tools/debugger/kdd/Makefile" ?

Jan, Andrew, Roger, could you give a ack or review this patch, for the
change in "tools/fuzz/cpu-policy/Makefile" and
"tools/tests/cpu-policy/Makefile" ?

George, could you give a ack or review this patch, for the change in
"tools/xentrace/Makefile" ?

I would also need a review from someone on the whole patch.

Also, sorry to Jan, Andrew, and George, it seems that the use of
"--remove-duplicates" with `get_maintainer.pl` have removed your emails
from CC the list.

Thanks,

Hi Jan,

Thanks. I think the following are ready, they don't depend on
uncommitted patches:

15: tools: Introduce $(xenlibs-rpath,..) to replace $(SHDEPS_lib*)
16: tools: Introduce $(xenlibs-ldlibs, ) macro
18: tools/helper: Cleanup Makefile
19: tools/console: Use $(xenlibs-ldlibs,)


Also, while "tools: Add -Werror by default to all tools/" seems ready,
it's probably better to have committed at the same time as the follow-up
"tools: Remove -Werror everywhere else".

Cheers,

Hello all,

It=E2=80=99s come to my attention that the commits below are tagged as =
=E2=80=9CSuggested-by=E2=80=9D someone, and that person doesn=E2=80=99t =
believe the tag to be accurate.  Having talked to most of the other =
committers, we decided to revert the commits and re-apply them with the =
offending tag removed; this will make it clear to anyone doing a =E2=80=9C=
git blame=E2=80=9D who not to blame.

This does open the question about unwanted / disputed tags in general; =
we can have a discussion about an official policy on it at some point.

Thanks,
 -George

My goal is not to change the existing license on any of the files, even
if the existing license is imprecise. By what is written under COPYING,
everything not explicitly listed is GPL-2.0. I only reflected today's
reality. I think it is best if we keep mechanical changes separate from
"smart" changes, especially on a series like this introducing many
mechanical changes.  More on this at the bottom.

It is: the tag is described as part of LICENSES/GPL-2.0.

It could make sense to say that:

/* SPDX-License-Identifier: GPL-2.0 */

is recommended for new files.

Well spotted! Effectively this file is now declared as GPL 2.0 only,
given what is stated in COPYING. The code in domain_page has lost "or
later" with the loss of the copyright header.

So if there were new contributions to this file after its creation, they
would have been GPL-2.0 only contributions, and it would have been
impossible to go back to GPL-2.0-or-later without asking the copyright
owners of the new changes.

In this case thankfully there are no new contributions since the split
of the file, so I can fix it by using the SPDX GPL-2.0-or-later tag
without problems. I'll do it in the next version of the series.

Xen is not saying: "if there is no copyright header it might be GPLv2
but you need to look it up". Xen is actively saying: "if there is no
copyright header it is GPLv2". Not up for discussion. Given that as a
whole Xen is GPLv2, the only possibility is that the file without a
copyright header used to be:
- GPLv2 or later
- dual license GPL and another compatible license (e.g. BSD)

Either way, with the loss of the copyright header, the file becomes
immediately GPLv2 only.

Does it make sense?

This is why I think it is best to keep copyright discussions out of the
SPDX patches review and limit ourselves to mechanical changes.

Hello,

I used to send out RFC v1 to introduce an extra io_tlb_mem (created with
SWIOTLB_ANY) in addition to the default io_tlb_mem (32-bit).  The
dev->dma_io_tlb_mem is set to either default or the extra io_tlb_mem,
depending on dma mask. However, that is not good for setting
dev->dma_io_tlb_mem at swiotlb layer transparently as suggested by
Christoph Hellwig.

https://lore.kernel.org/all/20220609005553.30954-1-dongli.zhang@oracle.com/

Therefore, this is another RFC v2 implementation following a different
direction. The core ideas are:

1. The swiotlb is splited into two zones, io_tlb_mem->zone[0] (32-bit) and
io_tlb_mem->zone[1] (64-bit).

struct io_tlb_mem {
	struct io_tlb_zone zone[SWIOTLB_NR];
	struct dentry *debugfs;
	bool late_alloc;
	bool force_bounce;
	bool for_alloc;
	bool has_extra;
};

struct io_tlb_zone {
	phys_addr_t start;
	phys_addr_t end;
	void *vaddr;
	unsigned long nslabs;
	unsigned long used;
	unsigned int nareas;
	unsigned int area_nslabs;
	struct io_tlb_area *areas;
	struct io_tlb_slot *slots;
};

2. By default, only io_tlb_mem->zone[0] is available. The
io_tlb_mem->zone[1] is allocated conditionally if:

- the "swiotlb=" is configured to allocate extra buffer, and
- the SWIOTLB_EXTRA is set in the flag (this is to make sure arch(s) other
  than x86/sev/xen will not enable it until it is fully tested by each
  arch, e.g., mips/powerpc). Currently it is enabled for x86 and xen.

3. During swiotlb map, whether zone[0] (32-bit) or zone[1] (64-bit
SWIOTLB_ANY)
is used depends on min_not_zero(*dev->dma_mask, dev->bus_dma_limit).

To test the RFC v2, here is the QEMU command line.

qemu-system-x86_64 -smp 8 -m 32G -enable-kvm -vnc :5 -hda disk.img \
-kernel path-to-linux/arch/x86_64/boot/bzImage \
-append "root=/dev/sda1 init=/sbin/init text console=ttyS0 loglevel=7 swiotlb=32768,4194304,force" \
-net nic -net user,hostfwd=tcp::5025-:22 \
-device nvme,drive=nvme01,serial=helloworld -drive file=test.qcow2,if=none,id=nvme01 \
-serial stdio

There is below in syslog. The extra 8GB buffer is allocated.

[    0.152251] software IO TLB: area num 8.
... ...
[    3.706088] PCI-DMA: Using software bounce buffering for IO (SWIOTLB)
[    3.707334] software IO TLB: mapped default [mem 0x00000000bbfd7000-0x00000000bffd7000] (64MB)
[    3.708585] software IO TLB: mapped extra [mem 0x000000061cc00000-0x000000081cc00000] (8192MB)

After the FIO is triggered over NVMe, the 64-bit buffer is used.

$ cat /sys/kernel/debug/swiotlb/io_tlb_nslabs_extra
4194304
$ cat /sys/kernel/debug/swiotlb/io_tlb_used_extra
327552

Would you mind helping if this is the right direction to go?

Thank you very much!

Subject: [PATCH v2 03/10] x86/mtrr: replace use_intel() with a local flag
Date: Sat, 20 Aug 2022 11:25:26 +0200
Message-Id: <20220820092533.29420-4-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
In-Reply-To: <20220820092533.29420-1-jgross@suse.com>
References: <20220820092533.29420-1-jgross@suse.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

In MTRR code use_intel() is only used in one source file, and the
relevant use_intel_if member of struct mtrr_ops is set only in
generic_mtrr_ops.

Replace use_intel() with a single flag in cacheinfo.c, which can be set
when assigning generic_mtrr_ops to mtrr_if. This allows to drop
use_intel_if from mtrr_ops, while preparing to support PAT without
MTRR. As another preparation for the PAT/MTRR decoupling use a bit for
MTRR control and one for PAT control. For now set both bits together,
this can be changed later.

As the new flag will be set only if mtrr_enabled is set, the test for
mtrr_enabled can be dropped at some places.

At the same time drop the local mtrr_enabled() function and rename
the __mtrr_enabled flag to mtrr_enabled.

Subject: [PATCH v2 09/10] x86/mtrr: add a stop_machine() handler calling only cache_cpu_init()
Date: Sat, 20 Aug 2022 11:25:32 +0200
Message-Id: <20220820092533.29420-10-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
In-Reply-To: <20220820092533.29420-1-jgross@suse.com>
References: <20220820092533.29420-1-jgross@suse.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Instead of having a stop_machine() handler for either a specific MTRR
register or all state at once, add a handler just for calling
cache_cpu_init() if appropriate.

Add functions for calling stop_machine() with this handler as well.

Add a generic replacements for mtrr_bp_restore() and a wrapper for
mtrr_bp_init().

Signed-off-by: Juergen Gross <jgross@suse.com>

V2:
- completely new replacement of former patch 2

Subject: [PATCH v2 06/10] x86/mtrr: remove set_all callback from struct mtrr_ops
Date: Sat, 20 Aug 2022 11:25:29 +0200

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Instead of using an indirect call to mtrr_if->set_all just call the
only possible target cache_cpu_init() directly. This enables to remove
the set_all callback from struct mtrr_ops.

Subject: [PATCH v2 07/10] x86/mtrr: simplify mtrr_bp_init()
Date: Sat, 20 Aug 2022 11:25:30 +0200

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

In case of the generic cache interface being used (Intel cpus or a
64-bit system), the initialization sequence of the boot cpu is more
complicated as necessary:

- check if MTRR enabled, if yes, call mtrr_bp_pat_init() which will
  disable caching, set the PAT MSR, and reenable caching

- call mtrr_cleanup(), in case that changed anything, call
  cache_cpu_init() doing the same caching disable/enable dance as
  above, but this time with setting the (modified) MTRR state (even
  if MTRR was disabled) AND setting the PAT MSR (again even with
  disabled MTRR)

The sequence can be simplified a lot while removing potential
inconsistencies:

- check if MTRR enabled, if yes, call mtrr_cleanup() and then
  cache_cpu_init()

This ensures to:

- no longer disable/enable caching more than once

- avoid to set MTRRs and/or the PAT MSR on the boot processor in case
  of MTRR cleanups even if MTRRs meant to be disabled

With that mtrr_bp_pat_init() can be removed.

Subject: [PATCH v2 02/10] x86/mtrr: remove unused cyrix_set_all() function
Date: Sat, 20 Aug 2022 11:25:25 +0200
Message-Id: <20220820092533.29420-3-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
In-Reply-To: <20220820092533.29420-1-jgross@suse.com>

Content-Transfer-Encoding: 8bit

The Cyrix cpu specific MTRR function cyrix_set_all() will never be
called, as the struct mtrr_ops set_all() callback will only be called
in the use_intel() case, which would require the use_intel_if member
of struct mtrr_ops to be set, which isn't the case for Cyrix.

Subject: [PATCH v2 01/10] x86/mtrr: fix MTRR fixup on APs

When booting or resuming the system MTRR state is saved on the boot
processor and then this state is loaded into MTRRs of all other cpus.
During update of the MTRRs the MTRR mechanism needs to be disabled by
writing the related MSR. The old contents of this MSR are saved in a
set of static variables and later those static variables are used to
restore the MSR.

In case the MSR contents need to be modified on a cpu due to the MSR
not having been initialized properly by the BIOS, the related update
function is modifying the static variables accordingly.

Unfortunately the MTRR state update is usually running on all cpus
at the same time, so using just one set of static variables for all
cpus is racy in case the MSR contents differ across cpus.

Fix that by using percpu variables for saving the MSR contents.

I thought adding a "Fixes:" tag for the kernel's initial git commit
would maybe be entertaining, but without being really helpful.
The percpu variables were preferred over on-stack ones in order to
avoid more code churn in followup patches decoupling PAT from MTRR
support.

Subject: [PATCH v2 00/10] x86: make pat and mtrr independent from each other
Date: Sat, 20 Aug 2022 11:25:23 +0200
Message-Id: <20220820092533.29420-1-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Today PAT can't be used without MTRR being available, unless MTRR is at
least configured via CONFIG_MTRR and the system is running as Xen PV
guest. In this case PAT is automatically available via the hypervisor,
but the PAT MSR can't be modified by the kernel and MTRR is disabled.

The same applies to a kernel built with no MTRR support: it won't
allow to use the PAT MSR, even if there is no technical reason for
that, other than setting up PAT on all cpus the same way (which is a
requirement of the processor's cache management) is relying on some
MTRR specific code.

Fix all of that by:

- moving the function needed by PAT from MTRR specific code one level
  up
- reworking the init sequences of MTRR and PAT to be more similar to
  each other without calling PAT from MTRR code
- removing the dependency of PAT on MTRR

While working on that I discovered two minor bugs in MTRR code, which
are fixed, too.

Changes in V2:
- complete rework of the patches based on comments by Boris Petkov
- added several patches to the series

Juergen Gross (10):
  x86/mtrr: fix MTRR fixup on APs
  x86/mtrr: remove unused cyrix_set_all() function
  x86/mtrr: replace use_intel() with a local flag
  x86: move some code out of arch/x86/kernel/cpu/mtrr
  x86/mtrr: split generic_set_all()
  x86/mtrr: remove set_all callback from struct mtrr_ops
  x86/mtrr: simplify mtrr_bp_init()
  x86/mtrr: let cache_aps_delayed_init replace mtrr_aps_delayed_init
  x86/mtrr: add a stop_machine() handler calling only cache_cpu_init()
  x86: decouple pat and mtrr handling

Subject: [PATCH v2 05/10] x86/mtrr: split generic_set_all()
Date: Sat, 20 Aug 2022 11:25:28 +0200

MIME-Version: 1.0

Split generic_set_all() into multiple parts, while moving the main
function body into cacheinfo.c.

This prepares the support of PAT without needing MTRR support by
moving the main function body of generic_set_all() into cacheinfo.c
while renaming it to cache_cpu_init(). The MTRR specific parts are
moved into a dedicated small function called by cache_cpu_init().
The PAT and MTRR specific functions are called conditionally based
on the cache_generic bit settings.

The setting of smp_changes_mask is merged into the (new) function
mtrr_generic_set_state() used to call set_mtrr_state(). It was
probably split in ancient times, as atomic operations while running
uncached might be quite expensive, but OTOH only systems with a
broken BIOS should ever require to set any bit in smp_changes_mask,
so just hurting those devices with a penalty of a few microseconds
during boot shouldn't be a real issue.

Subject: [PATCH v2 10/10] x86: decouple pat and mtrr handling
Date: Sat, 20 Aug 2022 11:25:33 +0200
Message-Id: <20220820092533.29420-11-jgross@suse.com>

Today PAT is usable only with MTRR being active, with some nasty tweaks
to make PAT usable when running as Xen PV guest, which doesn't support
MTRR.

The reason for this coupling is, that both, PAT MSR changes and MTRR
changes, require a similar sequence and so full PAT support was added
using the already available MTRR handling.

Xen PV PAT handling can work without MTRR, as it just needs to consume
the PAT MSR setting done by the hypervisor without the ability and need
to change it. This in turn has resulted in a convoluted initialization
sequence and wrong decisions regarding cache mode availability due to
misguiding PAT availability flags.

Fix all of that by allowing to use PAT without MTRR and by reworking
the current PAT initialization sequence to match better with the newly
introduced generic cache initialization.

This removes the need of the recently added pat_force_disabled flag, so
remove the remnants of the patch adding it.

Version: 6.0-rc1

Description:=20

In function 'privcmd_ioctl_dm_op' (drivers/xen/privcmd.c: 615)return
value of 'kcalloc' with GFP_KERNEL flag is assigned to "pages"
variable. GFP_KERNEL flag does not guarantee, that the return value
will not be NULL. In that case, there is a jump to the "out" label.=20

---------------------------------------------------------------------
667	pages =3D kcalloc(nr_pages, sizeof(*pages), GFP_KERNEL);
668	if (!pages) {
669		rc =3D -ENOMEM;
670		goto out;
671	}
---------------------------------------------------------------------

Variable 'pages' is passed to function 'unpin_user_pages_dirty_lock' as
1st parameter at [drivers/xen/privcmd.c: 695].

---------------------------------------------------------------------
694	out:
695		unlock_pages(pages, nr_pages);
---------------------------------------------------------------------

Then, variable 'pages' is passed to function
'unpin_user_pages_dirty_lock' as 1st parameter at
[drivers/xen/privcmd.c: 612].

---------------------------------------------------------------------
610	static void unlock_pages(struct page *pages[], unsigned int
nr_pages)
611	{
612		unpin_user_pages_dirty_lock(pages, nr_pages, true);
613	}
---------------------------------------------------------------------

'pages' and 'npages' are passed as parameters to function
'sanity_check_pinned_pages' at [mm/gup.c: 311].

---------------------------------------------------------------------
299	void unpin_user_pages_dirty_lock(struct page **pages, unsigned
long npages,
300					 bool make_dirty)
301	{
302		unsigned long i;
303     struct folio *folio;
304     unsigned int nr;
305	=09
306		if (!make_dirty) {
307			unpin_user_pages(pages, npages);
308			return;
309		}
310
311		sanity_check_pinned_pages(pages, npages);
---------------------------------------------------------------------

In function 'sanity_check_pinned_pages', if
(IS_ENABLED(CONFIG_DEBUG_VM)) and (npages > 0), NULL pointer 'pages' is
dereferenced at [mm/gup.c: 51].

---------------------------------------------------------------------
32	static inline void sanity_check_pinned_pages(struct page
**pages,
33						     unsigned long
npages)
34	{
35		if (!IS_ENABLED(CONFIG_DEBUG_VM))
36			return;
..
50		for (; npages; npages--, pages++) {
51			struct page *page =3D *pages;
								^^^^^^
^
---------------------------------------------------------------------

Else if (!IS_ENABLED(CONFIG_DEBUG_VM)) and (npages > 0) function
'gup_folio_next' is called with 'pages' and 'npages' as parameters at
[mm/gup.c: 311].

---------------------------------------------------------------------
312		for (i =3D 0; i < npages; i +=3D nr) {
313			folio =3D gup_folio_next(pages, npages, i, &nr);
---------------------------------------------------------------------

In function 'gup_folio_next' NULL pointer 'list' is dereferenced at
[mm/gup.c: 263].

---------------------------------------------------------------------
262	static inline struct folio *gup_folio_next(struct page **list,
263			unsigned long npages, unsigned long i,
unsigned int *ntails)
264	{
265		struct folio *folio =3D page_folio(list[i]);
							=09
		^^^^^^^^^

I would say yes. You will need to tweak the first section of that file 
because it reference the section " COMMON COPYRIGHT NOTICES".

See my answer on patch 1 as wel.

reference to licenses for the full text.

Note that I don't think we should consolidate to a single COPYING file 
because the preferred license differs per directory.

I will answer to this at the bottom.

Ah! I was looking as the list of files and didn't look for the tag. 
Thanks for the pointer :).

So I was reading through xen/COPYING and we already have something like 
that:

"Note that the only valid version of the GPL as far as Xen is concerned
is _this_ particular version of the license (i.e., *only* v2, not v2.2
or v3.x or whatever), unless explicitly otherwise stated."

So nothing to add here unless you want to tell the contributor which tag 
correspond to GPLv2.

Yes. This was an oversight from me when I split the code a few weeks ago.

Yes I agree this series should be mechanical (baring the file that is 
contain GPLv2+ code).

I am putting some thoughts below (they can be split in a separate thread 
if you prefer).

This is not the first time this topic is brought up and probably not the 
last as long as we have file using GPLv2+.

IIRC from past discussion there are two broads concern with GPLv2+:
   - We are leaving the choice of which license applies to the person 
copying the code. So if a new version is released that is less favorable 
to the initial contributor, then we have no leverage.
   - Some companies are rather cautious to contribute code that my be 
licensed under GPLv3 (would be allowed with GPLv2+).

The later is particularly a problem because not many people realize that 
a fair part of Xen on Arm is GPLv2+. I never really understood why we 
chose that (this was before my time) but this got spread as the existing 
copyright was added to a new file. Admittely, the contributor should be 
more cautious. But I would not say this is trivial to spot the difference.

I would like to consider to re-license all the GPLv2+ files to GPLv2. 
AFAIU, this would mean we would need to ask the permission for every 
comapany that contributed to the file. Do you know if this was done 
before in Xen Project?

Cheers,

So if that thing has been broken for so long and no one noticed, we
could just as well not backport to stable at all...

My APM says that the high 32 bits of the MTRRdefType MSR are reserved
and MBZ. So you can drop the _hi thing and use 0 everywhere. Or rather a
dummy = 0 var because of that damn rdmsr() macro.

Or simply use a

u64 deftype;

use the rdmsrl/wrmsrl() variants and split it when passing to
umtrr_wrmsr() because that thing wants 2 32s.

The tip-tree preferred ordering of variable declarations at the
beginning of a function is reverse fir tree order::

	struct long_struct_name *descriptive_name;
	unsigned long foo, bar;
	unsigned int tmp;
	int ret;

The above is faster to parse than the reverse ordering::

	int ret;
	unsigned int tmp;
	unsigned long foo, bar;
	struct long_struct_name *descriptive_name;

And even more so than random ordering::

	unsigned long foo, bar;
	int ret;
	struct long_struct_name *descriptive_name;
	unsigned int tmp;

Please check all your patches.

You don't need the pointers here - this_cpu_read() should be enough.

I have reproduced this on current staging(*). And I can reproduce it
reliably. And also, I got (I believe) closely related crash with credit1
scheduler.

(*) It isn't plain staging, it's one with my xhci console patches on
top, including attempt to make it survive S3. I believe the only
relevant part there is sticking set_timer() into console resume path (or
just having a timer with rather short delay registered). The actual tree
at https://github.com/marmarek/xen/tree/master-xue2-debug, including
quite a lot of debug prints and debug hacks.

I'm not sure about the nature of credit2 crash, but for credit1 it looks
much simpler to understand. Credit1 registers a timer for each pcpu (in
init_pdata()). Then, the timer function
(csched_tick()->csched_unit_acct()) asserts if it was really called on
correct CPU. The issue is that suspend path migrates all timers to CPU0
(timerc.:cpu_callback->migrate_timers_from_cpu()), and restore path
doesn't migrate them back. All this while not unregistering pCPUs from
the scheduler (sched_deinit_pdata() / init_pdata() is not called -
confirmed via debug prints).

I'm not exactly sure if that's the same issue that applies to credit2,
but I think it's likely. A naive fix could be unregistering all pCPUs
=66rom the scheduler (an registering them back on resume), but this may
mess up CPU pools, and probably few other things. Any better ideas? I
can test various patches, provide more debug info etc - should be rather
straightforward given I have reliable reproducer now.

Yeah, you can't do that.

The whole day today I kept thinking that something's wrong with this
here. As in, why hasn't it been reported until now.

You say above:

"... for all cpus is racy in case the MSR contents differ across cpus."

But they don't differ:

"7.7.5 MTRRs in Multi-Processing Environments

In multi-processing environments, the MTRRs located in all processors
must characterize memory in the same way. Generally, this means that
identical values are written to the MTRRs used by the processors. This
also means that values CR0.CD and the PAT must be consistent across
processors. Failure to do so may result in coherency violations or loss
of atomicity. Processor implementations do not check the MTRR settings
in other processors to ensure consistency. It is the responsibility of
system software to initialize and maintain MTRR consistency across all
processors."

And you can't have different fixed MTRR type on each CPU - that would
lead to all kinds of nasty bugs.

And here's from a big fat box:

$ rdmsr -a 0x2ff | uniq -c
    256 c00

All 256 CPUs have the def type set to the same thing.

Now, if all CPUs go write that same deftype_lo variable in the
rendezvous handler, the only issue that could happen is if a read
sees a partial write. BUT, AFAIK, x86 doesn't tear 32-bit writes so I
*think* all CPUs see the same value being corrected by using mtrr_state
previously saved on the BSP.

As I said, we should've seen this exploding left and right otherwise...

Thx.

Hi,

This email is sent to discuss the possible Release Candidates (RCs) for
Xen 4.17 release. We are still 1+ month away from where they start but
we can start early to gather opinions from all stakeholders.

I checked the RC schedule when Xen 4.16 was released. The RCs were prepared
after the Code Freeze and there were 4 RCs one per week (Nov 1, 2021;
Nov 8, 2021;  Nov 16, 2021; Nov 23, 2021) before the final release (Dec 2,
2021).

For 4.17, the Code Freeze will happen in Fri Sep 23, 2022, which is also th=
e
week of Xen Summit, so I think the first RC can fall in the week after, so =
I
prepared below schedule:

RC1: Fri Sep 30, 2022.
RC2: Fri Oct 7, 2022.
RC3: Fri Oct 14, 2022 (The date of Hard Code Freeze).
RC4: Fri Oct 21, 2022.
RC5 (Final): Fri Oct 28, 2022 (The date of Final Commits).

Please kindly share your opinion on this schedule, thanks!

Kind regards,
Henry

(The Arm device tree based NUMA support patch set contains 35
patches. In order to make stuff easier for reviewers, I split
them into 3 parts:
1. Preparation. I have re-sorted the patch series. And moved
   independent patches to the head of the series - merged in [1]
2. Move generically usable code from x86 to common - this series.
3. Add new code to support Arm.

This series only contains the second part patches. As the whole NUMA
series has been reviewed for 1 round in [2], so this series would
be v3)

Xen memory allocation and scheduler modules are NUMA aware.
But actually, on x86 has implemented the architecture APIs
to support NUMA. Arm was providing a set of fake architecture
APIs to make it compatible with NUMA awared memory allocation
and scheduler.

Arm system was working well as a single node NUMA system with
these fake APIs, because we didn't have multiple nodes NUMA
system on Arm. But in recent years, more and more Arm devices
support multiple nodes NUMA system.

So now we have a new problem. When Xen is running on these Arm
devices, Xen still treat them as single node SMP systems. The
NUMA affinity capability of Xen memory allocation and scheduler
becomes meaningless. Because they rely on input data that does
not reflect real NUMA layout.

Xen still think the access time for all of the memory is the
same for all CPUs. However, Xen may allocate memory to a VM
from different NUMA nodes with different access speeds. This
difference can be amplified in workloads inside VM, causing
performance instability and timeouts.

So in this patch series, we implement a set of NUMA API to use
device tree to describe the NUMA layout. We reuse most of the
code of x86 NUMA to create and maintain the mapping between
memory and CPU, create the matrix between any two NUMA nodes.
Except ACPI and some x86 specified code, we have moved other
code to common. In next stage, when we implement ACPI based
NUMA for Arm64, we may move the ACPI NUMA code to common too,
but in current stage, we keep it as x86 only.

This patch serires has been tested and booted well on one
Arm64 NUMA machine and one HPE x86 NUMA machine.

v2 -> v3:
 1. Drop enumeration of numa status.
 2. Use helpers to get/update acpi_numa.
 3. Insert spaces among parameters of strncmp in numa_setup.
 4. Drop helpers to access mem_hotplug. Export mem_hotplug for all arch.
 5. Remove acpi.h from common/numa.c.
 6. Rename acpi_scan_nodes to numa_scan_nodes.
 7. Replace u8 by uint8_t for memnodemap.
 8. Use unsigned int for memnode_shift and adjust related functions
    (compute_hash_shift, populate_memnodemap) to use correct types for
    return values or parameters.
 9. Use nodeid_t for nodeid and node numbers.
10. Use __read_mostly and __ro_after_init for appropriate variables.
11. Adjust the __read_mostly and __initdata location for some variables.
12. Convert from plain int to unsigned for cpuid and other proper 
13. Remove unnecessary change items in history.
14. Rename arch_get_memory_map to arch_get_ram_range.
15. Use -ENOENT instead of -ENODEV to indicate end of memory map.
16. Add description to code comment that arch_get_ram_range returns
    RAM range in [start, end) format.
17. Rename bad_srat to numa_fw_bad.
18. Rename node_to_pxm to numa_node_to_arch_nid.
19. Merge patch#7 and #8 into patch#6.
20. Move NR_NODE_MEMBLKS from x86/acpi.h to common/numa.h
22. Use 2-64 for node range.

v1 -> v2:
 1. Refine the commit messages of several patches.
 2. Merge v1 patch#9,10 into one patch. Introduce the new functions
    in the same patch that this patch will be used first time.
 3. Fold if ( end > mem_hotplug ) to mem_hotplug_update_boundary,
    in this case, we can drop mem_hotplug_boundary.
 4. Remove fw_numa, use enumeration to replace numa_off and acpi_numa.
 5. Correct return value of srat_disabled.
 6. Introduce numa_enabled_with_firmware.
 7. Refine the justification of using !node_data[nid].node_spanned_pages.
 8. Use ASSERT to replace VIRTUAL_BUG_ON in phys_to_nid.
 9. Adjust the conditional express for ASSERT.
10. Move MAX_NUMNODES from xen/numa.h to asm/numa.h for x86.
11. Use conditional macro to gate MAX_NUMNODES for other architectures.
12. Use arch_get_memory_map to replace arch_get_memory_bank_range
    and arch_get_memory_bank_number.
13. Remove the !start || !end check, because caller guarantee
    these two pointers will not be NULL.
14. Add code comment for numa_update_node_memblks to explain:
    Assumes all memory regions belonging to a single node
    are in one chunk. Holes between them will be included
    in the node.
15. Merge this single patch instead of serval patches to move
    x86 SRAT code to common.
16. Export node_to_pxm to keep pxm information in NUMA scan
    nodes error messages.
17. Change the code style to target file's Xen code-style.
18. Adjust some __init and __initdata for some functions and
    variables.
19. Replace CONFIG_ACPI_NUMA by CONFIG_NUMA. Replace "SRAT" texts.
20. Turn numa_scan_nodes to static.
21. Change NR_NUMA_NODES upper bound from 4095 to 255.

Wei Chen (6):
  xen/x86: Provide helpers for common code to access acpi_numa
  xen/x86: move generically usable NUMA code from x86 to common
  xen/x86: Use ASSERT instead of VIRTUAL_BUG_ON for phys_to_nid
  xen/x86: use arch_get_ram_range to get information from E820 map
  xen/x86: move NUMA scan nodes codes from x86 to common
  xen: introduce a Kconfig option to configure NUMA nodes number

The sanity check of nodes_cover_memory is also a requirement of
other architectures that support NUMA. But now, the code of
nodes_cover_memory is tied to the x86 E820. In this case, we
introduce arch_get_ram_range to decouple architecture specific
memory map from this function. This means, other architectures
like Arm can also use it to check its node and memory coverage
from bootmem info.

Depends arch_get_ram_range, we make nodes_cover_memory become
architecture independent. We also use neutral words to replace
SRAT and E820 in the print message of this function. This will
to make the massage seems more common.

As arch_get_ram_range use unsigned int for index, we also adjust
the index in nodes_cover_memory from int to unsigned int.

v2 -> v3:
1. Rename arch_get_memory_map to arch_get_ram_range.
2. Use -ENOENT instead of -ENODEV to indicate end of memory map.
3. Add description to code comment that arch_get_ram_range returns
   RAM range in [start, end) format.
v1 -> v2:
1. Use arch_get_memory_map to replace arch_get_memory_bank_range
   and arch_get_memory_bank_number.
2. Remove the !start || !end check, because caller guarantee
   these two pointers will not be NULL.

VIRTUAL_BUG_ON is an empty macro used in phys_to_nid. This
results in two lines of error-checking code in phys_to_nid
that is not actually working and causing two compilation
errors:
1. error: "MAX_NUMNODES" undeclared (first use in this function).
   This is because in the common header file, "MAX_NUMNODES" is
   defined after the common header file includes the ARCH header
   file, where phys_to_nid has attempted to use "MAX_NUMNODES".
   This error was resolved after we moved the phys_to_nid from
   x86 ARCH header file to common header file.
2. error: wrong type argument to unary exclamation mark.
   This is because, the error-checking code contains !node_data[nid].
   But node_data is a data structure variable, it's not a pointer.

So, in this patch, we use ASSERT instead of VIRTUAL_BUG_ON to
enable the two lines of error-checking code. And fix the left
compilation errors by replacing !node_data[nid] to
!node_data[nid].node_spanned_pages. Although NUMA allows one node
can only have CPUs but without any memory. And node with 0 bytes
of memory might have an entry in memnodemap[] theoretically. But
that doesn't mean phys_to_nid can find any valid address from a
node with 0 bytes memory.

v2 -> v3:
1. Remove unnecessary change items in history.
2. Add Acked-by.
v1 -> v2:
1. Use ASSERT to replace VIRTUAL_BUG_ON in phys_to_nid.
2. Adjust the conditional express for ASSERT.
3. Refine the justification of using !node_data[nid].node_spanned_pages.

acpi_numa is a specific NUMA switch for ACPI NUMA implementation.
Other NUMA implementation may not need this switch. But this switch is
not only used by ACPI code, it is also used directly in some general
NUMA logic code. So far this hasn't caused any problem because Xen only
has x86 implementing ACPI NUMA, but now Arm is implementing device tree
based NUMA. Accesssing acpi_numa directly in some functions will be a
block of reusing NUMA common code. It is also difficult for us to replace
it with a new generic switch, because it is hard to prove that the new
switch states can guarantee the original code will work correctly.

So in this patch, we provide two helpers for common code to update and
get states of acpi_numa. And other new NUMA implementations just need
to provide the same helpers for common code. In this case, the generic
NUMA logic code can be reused by all NUMA implementations.

v2 -> v3:
1. Drop enumeration of numa status.
2. Use helpers to get/update acpi_numa.
3. Insert spaces among parameters of strncmp in numa_setup.
v1 -> v2:
1. Remove fw_numa.
2. Use enumeration to replace numa_off and acpi_numa.
3. Correct return value of srat_disabled.
4. Introduce numa_enabled_with_firmware.

There are some codes in x86/numa.c can be shared by common
architectures to implememnt NUMA support. Just like some
variables and functions to check and store NUMA memory map.
And some variables and functions to do NUMA initialization.

In this patch, we move them to common/numa.c and xen/numa.h
and use the CONFIG_NUMA to gate them for non-NUMA supported
architectures. As the target header file is Xen-style, so
we trim some spaces and replace tabs for the codes that has
been moved to xen/numa.h at the same time.

As acpi_scan_nodes has been used in a common function, it
doesn't make sense to use acpi_xxx in common code, so we
rename it to numa_scan_nodes in this patch too. After that
if we still use CONFIG_ACPI_NUMA in to gate numa_scan_nodes
in numa_initmem_init, that doesn't make sense. As CONFIG_NUMA
will be selected by CONFIG_ACPI_NUMA for x86. So, we replace
CONFIG_ACPI_NUMA by CONFIG_NUMA to gate numa_scan_nodes.

As arch_numa_disabled has been implememnted for ACPI NUMA,
we can rename srat_disabled to numa_disabled and move it
to common code as well.

v2 -> v3:
 1. Remove acpi.h from common/numa.c.
 2. Rename acpi_scan_nodes to numa_scan_nodes.
 3. Replace u8 by uint8_t for memnodemap.
 4. Use unsigned int for memnode_shift and adjust related functions
    (compute_hash_shift, populate_memnodemap) to use correct types for
    return values or parameters.
 5. Use nodeid_t for nodeid and node numbers.
 6. Use __read_mostly and __ro_after_init for appropriate variables.
 7. Adjust the __read_mostly and __initdata location for some variables.
 8. convert from plain int to unsigned for cpuid and other proper variables.
 9. Use __attribute_pure__ instead of __attribute__((pure)).
10. Replace CONFIG_ACPI_NUMA by CONFIG_NUMA in numa_initmem_init.
11. Add const for some functions' parameters.
12. Move srat_disabled to common code with new name numa_disabled.
13. Fix some spaces code-style for numa_emulation.
14. Change from int to unsigned int for numa_fake.
v1 -> v2:
1. New patch in v2.

x86 has implemented a set of codes to scan NUMA nodes. These
codes will parse NUMA memory and processor information from
ACPI SRAT table. But except some ACPI specific codes, most
of the scan codes like memory blocks validation, node memory
range updates and some sanity check can be reused by other
NUMA implementation.

So in this patch, we move some variables and related functions
for NUMA memory and processor to common as library. At the
same time, numa_set_processor_nodes_parsed has been introduced
for ACPI specific code to update processor parsing results.
With this helper, we can reuse most of NUMA memory affinity init
code from ACPI. As bad_srat and node_to_pxm functions have been
used in common code to do architectural fallback and node to
architectural node info translation. But it doesn't make sense
to reuse the functions names in common code, we have rename them
to neutral names as well.

PXM is an ACPI specific item, we can't use it in common code
directly. As an alternative, we extend the parameters of
numa_update_node_memblks. The caller can pass the PXM as print
messages' prefix or as architectural node id. In this case, we
do not need to retain a lot of per-arch code but still can print
architectural log messages for different NUMA implementations.

mem_hotplug also has been accessing by common code, except x86,
other architectures like Arm will also want to implement memory
hotplug in future. We export mem_hotplug to common will not bring
any harm for Arm and we also can reduce some per-arch helpers to
access mem_hotplug.

As asm/acpi.h has been removed from common/numa.c, we have to
move NR_NODE_MEMBLKS from asm/acpi.h to xen/numa.h in this patch
as well.

v2 -> v3:
1. Add __ro_after_init to proper variables.
2. Rename bad_srat to numa_fw_bad.
3. Rename node_to_pxm to numa_node_to_arch_nid.
4. Merge patch#7 and #8 into this patch.
5. Correct int to unsigned int in proper places.
6. Move NR_NODE_MEMBLKS from x86/acpi.h to common/numa.h
7. Drop helpers to access mem_hotplug, we export mem_hotplug
   from x86/mm.c to common/page_alloc.c
v1 -> v2:
1. Add code comment for numa_update_node_memblks to explain:
   Assumes all memory regions belonging to a single node
   are in one chunk. Holes between them will be included
   in the node.
2. Merge this single patch instead of serval patches to move
   x86 SRAT code to common.
3. Export node_to_pxm to keep pxm information in NUMA scan
   nodes error messages.
4. Change the code style to target file's Xen code-style.
5. Adjust some __init and __initdata for some functions and
   variables.
6. Merge two patches into this patch:
   1. replace CONFIG_ACPI_NUMA by CONFIG_NUMA.
   2. replace "SRAT" texts.
7. Turn numa_scan_nodes to static.

Current NUMA nodes number is a hardcode configuration. This
configuration is difficult for an administrator to change
unless changing the code.

So in this patch, we introduce this new Kconfig option for
administrators to change NUMA nodes number conveniently.
Also considering that not all architectures support NUMA,
this Kconfig option only can be visible on NUMA enabled
architectures. Non-NUMA supported architectures can still
use 1 as MAX_NUMNODES.

As NODES_SHIFT is currently unused, we're taking this
opportunity to remove it.

v2 -> v3:
1. Fix indent.
2. Use 2-64 for node range.
v1 -> v2:
1. Add NODES_SHIFT remove message in commit log
2. Change NR_NUMA_NODES upper bound from 4095 to 255.

That thing also says:

        pr_info("mtrr: probably your BIOS does not setup all CPUs.\n");
        pr_info("mtrr: corrected configuration.\n");

because it'll go and force on all CPUs the MTRR state it read from the
BSP in mtrr_bp_init->get_mtrr_state.

Well, my workstation says:

$ dmesg | grep -i mtrr
[    0.391514] mtrr: your CPUs had inconsistent variable MTRR settings
[    0.395199] mtrr: probably your BIOS does not setup all CPUs.
[    0.399199] mtrr: corrected configuration.

but that's the variable MTRRs.

My reasoning says you should not do anything at all here - works as
advertized. :-)

Subject: [PATCH V5 0/6] Virtio toolstack support for I2C and GPIO on Arm
Date: Mon, 22 Aug 2022 14:45:12 +0530
Message-Id: <cover.1661159474.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Hello,

This patchset adds toolstack support for I2C and GPIO virtio devices. This is
inspired from the work done by Oleksandr for the Disk device.

This is developed as part of Linaro's Project Stratos, where we are working
towards Hypervisor agnostic Rust based backend [1].

This is based of origin/staging (commit f6cd15188e09 ("amd/msr: implement
VIRT_SPEC_CTRL for HVM guests using legacy SSBD")) which already has Oleksandr's
patches applied.

V4->V5:
- Fixed indentation at few places.
- Removed/added blank lines.
- Added few comments.
- Added review tags from Oleksandr.
- Rebased over latest staging branch.

V3->V4:
- Update virtio_enabled independently of all devices, so we don't miss setting
  it to true.

- Add iommu handling for i2c/gpio and move it as part of
  make_virtio_mmio_node_common(), which gets backend_domid parameter as a
  result.

V2->V3:
- Rebased over latest tree and made changes according to changes in Oleksandr's
  patches from sometime back.
- Minor cleanups.

V1->V2:
- Patches 3/6 and 4/6 are new.

Subject: [PATCH V5 4/6] libxl: arm: Split make_virtio_mmio_node()
Date: Mon, 22 Aug 2022 14:45:16 +0530
Message-Id: <981b663f6a44f9f82f32cc58219f6af26f73d66f.1661159474.git.viresh.kumar@linaro.org>

make_virtio_mmio_node() creates the DT node for simple MMIO devices
currently, i.e. the ones that don't require any additional properties.

In order to allow using it for other complex device types, split the
functionality into two, one where the fdt node isn't closed and the
other one to create a simple DT node.

Subject: [PATCH V5 1/6] libxl: Add support for Virtio I2C device
Date: Mon, 22 Aug 2022 14:45:13 +0530
Message-Id: <8b47d98cec83ca33a2b409c9371356820dd91b7a.1661159474.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
In-Reply-To: <cover.1661159474.git.viresh.kumar@linaro.org>
References: <cover.1661159474.git.viresh.kumar@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-i2c backend (emualator) which is intended to run out of
Qemu and could be run in any domain.

An example of domain configuration for Virtio I2c:
i2c = [ "" ]

Please note, this patch is not enough for virtio-i2c to work on Xen
(Arm), as for every Virtio device we need to allocate Virtio MMIO params
(IRQ and memory region) and pass them to the backend, also update Guest
device-tree. A subsequent patch will add these missing bits. For the
current patch, the default "irq" and "base" are just written to the
Xenstore.

Subject: [PATCH V5 2/6] libxl: Add support for Virtio GPIO device
Date: Mon, 22 Aug 2022 14:45:14 +0530
Message-Id: <8ce51411dd910ead787be4aabb7239fcb3689972.1661159474.git.viresh.kumar@linaro.org>
X-Mailer: git-send-email 2.31.1.272.g89b43f80a514
In-Reply-To: <cover.1661159474.git.viresh.kumar@linaro.org>
References: <cover.1661159474.git.viresh.kumar@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch adds basic support for configuring and assisting virtio-mmio
based virtio-gpio backend (emualator) which is intended to run out of
Qemu and could be run in any domain.

An example of domain configuration for Virtio Gpio:
gpio = [ "" ]

Please note, this patch is not enough for virtio-gpio to work on Xen
(Arm), as for every Virtio device we need to allocate Virtio MMIO params
(IRQ and memory region) and pass them to the backend, also update Guest
device-tree. A subsequent patch will add these missing bits. For the
current patch, the default "irq" and "base" are just written to the
Xenstore.

Create a separate routine to allocate base and irq for a device as the
same code will be required for each device type.

Subject: [PATCH V5 5/6] libxl: Allocate MMIO params for I2c device and update DT
Date: Mon, 22 Aug 2022 14:45:17 +0530
Message-Id: <7b871a16d981dcdc0046e6a69f77e2bcffe79065.1661159474.git.viresh.kumar@linaro.org>

This patch allocates Virtio MMIO params (IRQ and memory region) and pass
them to the backend, also update Guest device-tree based on Virtio I2C
DT bindings [1].

This also relocates the code responsible to call make_xen_iommu_node()
towards the end of the routine, so we create the node only once.

Yes, I agree with you but some older patches that I sent that were 
adding parentheses around the lhs of the assignments were not accepted 
and I thought that the rhs of the assignments as well these comparisons 
fall to the same category.

Personally, I would expect to see parentheses, also, around the macro 
parameters that are used as the lhs or the rhs of assignments, the 
operands of comparison or the arguments of a function.
Not only because they can prevent against unintentional bugs but because 
the parentheses help me to identify more easily the macro parameters 
when reading a macro definition. I totally understand that for other 
people parentheses may reduce readability.

Subject: [PATCH v3 0/4] Make balloon drivers memory changes known to the rest of the kernel
Date: Mon, 22 Aug 2022 14:37:43 +0300
Message-Id: <20220822113747.3630776-1-alexander.atanasov@virtuozzo.com>
X-Mailer: git-send-email 2.31.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Currently balloon drivers (Virtio,XEN, HyperV, VMWare, ...)
inflate and deflate the guest memory size but there is no
way to know how much the memory size is changed by them.

A common use of the ballooning is to emulate [1]
hot plug and hot unplug - due to the complexity of the later.
Hotplug has a notifier and one can also check the updated
memory size.

To improve this add InflatedTotal and InflatedFree
to /proc/meminfo and implement a balloon notifier.

Amount of inflated memory can be used:
 - si_meminfo(..) users can improve calculations
 - adjust cache/buffer sizes
 - adjust object/connection limits
 - as a hint for the oom a killer
 - by user space software that monitors memory pressure

Patches for the other balloon drivers will be done next.

Alexander Atanasov (4):
  Make place for common balloon code
  Enable balloon drivers to report inflated memory
  Display inflated memory to users
  drivers: virtio: balloon - update inflated memory

 rename include/linux/{balloon_compaction.h => balloon.h} (86%)
 rename mm/{balloon_compaction.c => balloon.c} (88%)

v2:
 - reworked from simple /proc/meminfo addition
v3:
 - added missed EXPORT_SYMBOLS
Reported-by: kernel test robot <lkp@intel.com>
 - instead of balloon_common.h just use balloon.h (yes, naming is hard)
 - cleaned up balloon.h - remove from files that do not use it and
   remove externs from function declarations

While I'm mostly okay with the code, I think the description wants
changing / amending as long as the features talked about above aren't
anywhere near reaching upstream (afaict), to at least _also_ mention
the goal you have with this.

I guess you mean "avoid", not "fix".

This updating of d->valid_evtchns looks a little inconsistent to me,
wrt the uses of {read,write}_atomic(). To make obvious that there's
an implicit expectation that no 2nd invocation of this function
could race the updates, I'd recommend reading allocate_port ahead
of the loop and then never again. Here you'd then do

            smp_wmb();
            allocate_port += EVTCHNS_PER_BUCKET;
            write_atomic(&d->valid_evtchns, allocate_port);
        } while ( port >= allocate_port );

at the same time rendering the code (imo) a little more legible.

Makes me wonder whether the original change then really was worth it.

Rather than putting it at the very top of the file, may I suggest to put
it immediately after

/* --- CODE BELOW THIS LINE (MOSTLY) NOT GUEST RELATED --- */

or yet a few more lines down between continue_pv_domain and
restore_all_xen? Which, as a minor gain, then also doesn't require you
to add a new .text (or other section) directive. Preferably that way

Please clarify here how you arrived at 4096 and why you expect no
dom0less DomU would ever want to have more. The limit, after all,
is far below that of FIFO event channels.

I'm afraid the variable name doesn't express its purpose, and the

It's also not clear whether the constant really needs to live in
the already heavily overloaded xen/sched.h.

Subject: [PATCH v5 2/9] console: support multiple serial console simultaneously
Date: Mon, 22 Aug 2022 17:27:02 +0200

Previously only one serial console was supported at the same time. Using
console=com1,dbgp,vga silently ignored all but last serial console (in
this case: only dbgp and vga were active).

Fix this by storing not a single sercon_handle, but an array of them, up
to MAX_SERCONS entries. The value of MAX_SERCONS can be chosen in
kconfig, the default (4) is arbitrary, inspired by the number of
SERHND_IDX values.

Make console_steal() aware of multiple consoles too. It can now either
steal output from specific console (for gdbstub), or from all of them at
once (for console suspend).

Changes in v4:
- use unsigned int for loop counters
- other minor changes
Changes in v3:
- adjust console_steal() for multiple consoles too
- add MAX_SERCONS to kconfig
- add warning about sync_console impact
- add warning if too many consoles are configured
- log issue with PCI spec parsing

Subject: [PATCH v5 0/9] Add Xue - console over USB 3 Debug Capability
Date: Mon, 22 Aug 2022 17:27:00 +0200
Message-Id: <cover.4afa0fece5b70e838e4f1c7c7f25d0fa3d157073.1661181584.git-series.marmarek@invisiblethingslab.com>
X-Mailer: git-send-email 2.35.3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is integration of https://github.com/connojd/xue into mainline Xen.
This patch series includes several patches that I made in the process, some are
very loosely related.

The driver developed by Connor supports console via USB3 debug capability. The
capability is designed to operate mostly independently of normal XHCI driver,
so this patch series allows dom0 to drive standard USB3 controller part, while
Xen uses DbC for console output.

Changes since RFC:
 - move the driver to xue.c, remove non-Xen parts, remove now unneeded abstraction
 - adjust for Xen code style
 - build for x86 only
 - drop patch hidding the device from dom0
Changes since v1:
 - drop ehci patch - already applied
 - adjust for review comments from Jan (see changelogs in individual patches)
Changes since v2:
 - add runtime option to share (or not) the controller with dom0 or other domains
 - add RX support
 - several smaller changes according to review comments
Changes since v3:
 - put controller sharing behind experimental kconfig option
 - several other changes according to review comments
Changes since v4:
 - drop first 4 patches - already applied to staging
 - split dbgp=xhci into dbc=xhci

Marek Marczykowski-Górecki (9):
  drivers/char: separate dbgp=xhci to dbc=xhci option
  console: support multiple serial console simultaneously
  IOMMU: add common API for device reserved memory
  IOMMU/VT-d: wire common device reserved memory API
  IOMMU/AMD: wire common device reserved memory API
  drivers/char: mark DMA buffers as reserved for the XHCI
  drivers/char: add RX support to the XHCI driver
  drivers/char: allow driving the rest of XHCI by a domain while Xen uses DbC
  drivers/char: fix handling cable re-plug in XHCI console driver

Subject: [PATCH v5 3/9] IOMMU: add common API for device reserved memory
Date: Mon, 22 Aug 2022 17:27:03 +0200
Message-Id: <3ee5187c066ad12e3717df6fed41de99172271b0.1661181584.git-series.marmarek@invisiblethingslab.com>

Add API similar to rmrr= and ivmd= arguments, but in a common code. This
will allow drivers to register reserved memory regardless of the IOMMU
vendor.
The direct reason for this API is xhci-dbc console driver (aka xue),
that needs to use DMA. But future change may unify command line
arguments for user-supplied reserved memory, and it may be useful for
other drivers in the future too.

This commit just introduces an API, subsequent patches will plug it in
appropriate places. The reserved memory ranges needs to be saved
locally, because at the point when they are collected, Xen doesn't know
yet which IOMMU driver will be used.

Changes in v5:
- fix indentation, keep full "reserved_device_memory" for consistency
  with iommu_get_reserved_device_memory
Changes in v4:
- mark functions as __init
- use pci_sbdf_t type
Changes in v3:
 - adjust code style

The important part is to include those buffers in IOMMU page table
relevant for the USB controller. Otherwise, DbC will stop working as
soon as IOMMU is enabled, regardless of to which domain device assigned
(be it xen or dom0).
If the device is passed through to dom0 or other domain (see later
patches), that domain will effectively have access to those buffers too.
It does give such domain yet another way to DoS the system (as is the
case when having PCI device assigned already), but also possibly steal
the console ring content. Thus, such domain should be a trusted one.
In any case, prevent anything else being placed on those pages by adding
artificial padding.

Subject: [PATCH v5 7/9] drivers/char: add RX support to the XHCI driver
Date: Mon, 22 Aug 2022 17:27:07 +0200

Add another work ring buffer for received data, and point IN TRB at it.
Ensure there is always at least one pending IN TRB, so the controller
has a way to send incoming data to the driver.
Note that both "success" and "short packet" completion codes are okay -
in fact it will be "short packet" most of the time, as the TRB length is
about maximum size, not required size.

Subject: [PATCH v5 8/9] drivers/char: allow driving the rest of XHCI by a domain while Xen uses DbC

That's possible, because the capability was designed specifically to
allow separate driver handle it, in parallel to unmodified xhci driver
(separate set of registers, pretending the port is "disconnected" for
the main xhci driver etc). It works with Linux dom0, although requires
an awful hack - re-enabling bus mastering behind dom0's backs.
Linux driver does similar thing - see
drivers/usb/early/xhci-dbc.c:xdbc_handle_events().

When controller sharing is enabled in kconfig (option marked as
experimental), dom0 is allowed to use the controller even if Xen uses it
for debug console. Additionally, option `dbgp=xhci,share=` is available
to either prevent even dom0 from using it (`no` value), or allow any
domain using it (`any` value).

In any case, to avoid Linux messing with the DbC, mark this MMIO area as
read-only. This might cause issues for Linux's driver (if it tries to
write something on the same page - like anoter xcap), but makes Xen's
use safe. In practice, as of Linux 5.18, it seems to work without
issues.

Changes in v5:
- drop CONFIG_XHCI_SHARE
- make XHCI_SHARE_HWDOM = 0
- use parse_boolean
- add comment about mmio_ro_ranges
- fix doc
Changes in v4:
- minor fix for cmdline parsing
- make sharing opt-in build time, with option marked as EXPERIMENTAL
- change cmdline syntax to share=<bool>|hwdom
- make share=hwdom default (if enabled build-time)
Changes in v3:
- adjust for xhci-dbc rename
- adjust for dbc_ensure_running() split
- wrap long lines
- add runtime option for sharing USB controller

 Specify the USB controller to use, either by instance number (when going
 over the PCI busses sequentially) or by PCI device (must be on segment 0).
 
 XHCI driver will wait indefinitely for the debug host to connect - make sure
 the cable is connected.
+The `share` option for xhci controls who else can use the controller:
+* `no`: use the controller exclusively for console, even hardware domain
+  (dom0) cannot use it
+* `hwdom`: hardware domain may use the controller too, ports not used for debug
+  console will be available for normal devices; this is the default
+* `yes`: the controller can be assigned to any domain; it is not safe to assign
+  the controller to untrusted domain
+
+Choosing `share=hwdom` (the default) or `share=yes` allows a domain to reset the
+controller, which may cause small portion of the console output to be lost.
+
+The `share=yes` configuration is not security supported.

Subject: [PATCH v5 9/9] drivers/char: fix handling cable re-plug in XHCI console driver
Date: Mon, 22 Aug 2022 17:27:09 +0200
Message-Id: <bf26655295d0d85b1718d60f2e4390da7ec62b93.1661181584.git-series.marmarek@invisiblethingslab.com>

When cable is unplugged, dbc_ensure_running() correctly detects this
situation (DBC_CTRL_DCR flag is clear), and prevent sending data
immediately to the device. It gets only queued in work ring buffers.
When cable is plugged in again, subsequent dbc_flush() will send the
buffered data.
But there is a corner case, where no subsequent data was buffered in the
work buffer, but a TRB was still pending. Ring the doorbell to let the
controller re-send them. For console output it is rare corner case (TRB
is pending for a very short time), but for console input it is very
normal case (there is always one pending TRB for input).

Extract doorbell ringing into separate function to avoid duplication.

Subject: [PATCH] x86/domain: Fix struct domain memory corruption when building PV guests
Date: Mon, 22 Aug 2022 22:30:36 +0100

arch_domain_create() can't blindly write into d->arch.hvm union.  Move the
logic into hvm_domain_initialise(), which involves passing config down.

Fixes: 2ce11ce249a3 ("x86/HVM: allow per-domain usage of hardware virtualized APIC")

This does not fix XenServer's wall of red from testing, but I have at least
figured out what's going on.  There's a piece of plain RAM in place of a
working LAPIC MMIO mapping (accelerated or otherwise), which causes HVMLoader
to spin in a tight loop waiting for CPU 1 to come up after failing to send an
INIT-SIPI-SIPI.

Sadly the fix is not as straightforward as I'd hoped, and needs more testing.

I build and run it on armv8a, and start dom0 with two cpus. Cpu off and on =

While the SDM isn't very clear about this, our present behavior make
Linux 5.19 unhappy. As of commit 8ad7e8f69695 ("x86/fpu/xsave: Support
XSAVEC in the kernel") they're using this CPUID output also to size
the compacted area used by XSAVEC. Getting back zero there isn't really
liked, yet fpr PV that's the default on capable hardware: XSAVES isn't
exposed to PV domains.

Considering that the size reported is that of the compacted save area,
I view Linux'es assumption as appropriate (short of the SDM properly
considering the case). Therefore we need to populate the field also when
only XSAVEC is supported for a guest.

Fixes: 460b9a4b3630 ("x86/xsaves: enable xsaves/xrstors for hvm guest")
Fixes: 8d050ed1097c ("x86: don't expose XSAVES capability to PV guests")

I actually wonder why we surface the XSAVES feature bit to HVM domains,
when we don't support any of the features. It's solely because of this
that by default only PV domains are affected by the issue (HVM would be
affected only when XSAVES was hidden via guest config settings).
Wouldn't we better mask the bit (e.g. in recalculate_xstate()) when we
find that no features requiring XSAVES are visible to the domain? That
would likely come closer to real hardware, which pretty certainly won't
offer XSAVES without also offering at least one dependent feature.

Where's that page of plain RAM coming from? And do you meanwhile
understand why XenServer testing is exposing the issue while osstest
isn't?

May I ask for const to be added here? Unless you anticipate the
function might legitimately modify the config data?

Subject: =?utf-8?Q?=E2=80=9CBackend_has_not_unmappe?=
 =?utf-8?Q?d_grant=E2=80=9D?= errors

I recently had a VM=E2=80=99s /dev/xvdb stop working with a =E2=80=9Cbacken=
d has not
unmapped grant=E2=80=9D error.  Since /dev/xvdb was the VM=E2=80=99s privat=
e volume,
that rendered the VM effectively useless.  I had to kill it with
qvm-kill.

The backend of /dev/xvdb is dom0, so a malicious backend is clearly not
the cause of this.  I believe the actual cause is a race condition, such
as the following:

1. GUI agent in VM allocates grant X.
2. GUI agent tells GUI daemon in dom0 to map X.
3. GUI agent frees grant X.
4. blkfront allocates grant X and passes it to dom0.
5. dom0=E2=80=99s blkback maps grant X.
6. blkback unmaps grant X.
7. GUI daemon maps grant X.
8. blkfront tries to revoke access to grant X and fails.  Disaster
   ensues.

What could be done to prevent this race?  Right now all of the
approaches I can think of are horribly backwards-incompatible.  They
require replacing grant IDs with some sort of handle, and requiring
userspace to pass these handles to ioctls.  It is also possible that
netfront and blkfront could race against each other in a way that causes
this, though I suspect that race would be much harder to trigger.

This has happened more than once so it is not a fluke due to e.g. cosmic
rays or other random bit-flips.

Marek, do you have any suggestions?

I am not sure how this sentence is related to this patch. You...

... still need the limit to prevent a domain using more memory because 
at the moment they are unlimited.

I will reply on this because I suggested the limit. A dom0less DomU is 
exactly the same as a DomU created by the toolstack. The default is 1023 
(I originally thought it was 4096).

I would expect that is 1023 is going to be fine by default also for 
dom0less domU as on Arm we don't bind physical interrupts to event 
channels. So the only big use for them is for inter-domain communication.

Therefore, I think it should be ok to default to 1023 if we want 
consistency.

If someone needs more than 1023, we could introduce a per-domain 
device-tree property to override the default maximum.

IMHO, I think the value would be better hardcoded with an explanation on 
top how we chose the default value.

Correct, neither Guest Transparent Migration nor Live-Update is going to 
reach Xen in 4.17 :). Also, if we decide to continue to mention it, then
we would need to s/Guest Transparent Migration/non-cooperative 
migration/ to match the name we decided to use in upstream (see 
docs/designs/non-cooperative-migration.md).

Indeed that might be best, at least as long as no 2nd party appears.
What I was actually considering a valid reason for having a constant

Hi

I am able to mount 64GB usb drive to DomU  after changing the controller
version to 3.
USB device i am using is version 3.2 Gen2 but the controller attached to
DomU was version:2. So usbdev-attach failed earlier.

#sudo xl usbctrl-attach VM3 version=3 ports=6
#sudo xl usbdev-attach VM3 hostbus=3 hostaddr=2

With above commands, i am able to access usb storage in DomU.

i assume this is PVUSB method. Can someone confirm it ?


Thanks
Sudheer

The way it's written my assumption is that they simply didn't care about
XSAVEC when writing this, or they were assuming that both features would
always be supported together (yet even if they are in Intel's hardware,
the architecture should spell out things as if both were entirely
independent, or it should specify that one takes the other as a prereq).

I've made a request through my contact, but of course there's little
hope for a quick technical reply.

Hmm.

Why would that be? Both insns use compacted format, and neither is
dependent upon the other in terms of being supported. IOW XSAVES alone
and XSAVEC alone enabled for a domain should still lead through this
path.

Where do you see further complication? The necessary fiddling with XSS
here would of course be dependent upon p->xstate.xsaves alone (or,
maybe better, on the set of enabled features in XSS being non-empty),
but that's simply another (inner) if().

As an aside, I actually wonder what use the supplied size is to user
mode code when any XSS-controlled feature is enabled: They'd allocate
a needlessly large block of memory, as they would only be able to use
XSAVEC.

I think you are either missing a 'a' or 'ID' should be 'IDs'

AFAIU, this is meant to describe the static event channels for dom0. I 
can't find the documentation for it. Do they always need to be a subnode 
the node "multiboot,kernel"?

The reason I am asking is it feels strange to define them below that 
subnode when for domUs, both nodes have the same parent. So I think it 
would make more sense to define them in chosen.

Looking at the callers, they all assume that there is enough cells in 
the property. So I think you should check the size as well.

 From the binding description, the property is not optional. So do we 
want to ignore the error? If you treat it as an error, then ...

> +        if ( !prop || IS_ERR(prop) )
> +            return IS_ERR(prop) ? PTR_ERR(prop) : 0;

... you could return ERR_PTR(-ENOMEM) instead of NULL and then simplify 
this code with:

prop is a void pointer. So the cast is unnecessary.

> +        remote_phandle = dt_next_cell(1, &cell);
The code is also duplicated below for the remote port. I think it would 
be better if this is part of your helper get_evtchn_dt_property().

The loop could be avoided if you stash the domid in the field 'used_by' 
of the device-tree node when the domain is created.

Any particular reason to handle the hardware domain differently?

Please explain in a comment why you want to handle -EBUSY differently.

AFAIU, EBUSY only tells you the port is been used. It doesn't tell you 
the link is the same. So I think you want to also confirm that to avoid 
to continuing with the wrong setup.

AFAICT, all the users below can deal with constisfied node. So I think 
you want to add 'const' here.

If you follow my suggestion above, this should not be necessary. 
However, if this is still needed for some reason, then I think we should 
also set d->arch.node for the Hardware Domain and ...

Hi,

The documentation in docs/misc/arm/device-tree/booting.txt is missing. 
Also, you probably wants to update docs/feature/dom0less.pandoc because 
the section "PV drivers" suggests that if the property "xen,enhanced" is 
specified, then we would end up to allocate information for PV drivers.

AFAIU, this is not the case when "evtchn" is specified.

The diff below is quite difficult to read. I have applied to have a 
look. You seem to have simply indented the code and now some of the
lines are over the 80 characters mark.

Ideally, I would like to avoid large 'if'. So I would suggest to either
re-ordering the code or split in multiple functions.

However, reading the binding of "xen,xen", the property "reg" and 
"interrupts" are not optional.

I also don't think can make them optional because some OSes may not boot 
if it can't find one of the property.

In any case, at minimum you should explain why this is fine to make them 
optional.

So I understand why you want to make the first part optional. But this 
is not clear why this one become conditional to "dom0less_evtchn". Do 
you have any plan to only present the node "xen,xen" where neither event 
channels nor PV interfaces would be used?

I think the first part of the if can be removed because you can't do 
without event channel.

So technically, the event channel interface is still exposed even if 
this is false. This is because we are still allocate the PPI and set the 
number of events to a non-zero value.

IMHO, if dom0less_evtchn is false, then we should properly disable the 
event channels interface not just hide it.

If I am understanding right, GPLv2+ means that someone could relicense the =
files to GPLv3 if he wants which is more restrictive.
Why do you want to move those back to GPLv2 ?

Subject: [RFC PATCH] libacpi: Fix cross building x86 on arm
Date: Tue, 23 Aug 2022 11:24:15 +0100
Message-Id: <c3d431217010f669de809a76c2f1c15a0313ae53.1661246753.git.bertrand.marquis@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

When Xen is compiled for x86 on an arm machine, libacpi build is failing
due to a wrong include path:
- arch-x86/xen.h includes xen.h
- xen.h includes arch-arm.h (as __i386__ and __x86_64__ are not defined
but arm ones are).

To workaround this for now, enforce defining __x86_64__ in mk_dsdt.c
when compiled for x86 to follow the right include path.

Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
---
The x86 header is including ../xen.h before the ifndef/define so that it
gets included back by xen.h. This is wrongly making the assumption that
we are using an x86 compiler which is not the case when building the
tools for x86 on an arm host.
This patch is not a good solution but the headers are doing some weird
stuff which are going back to 2008 in the git history and the commit
message do not include any valid reason.

I never really understood why we chose that (this was before my time) but this got spread as the existing copyright was added to a new file. Admittely, the contributor should be more cautious.

The main difference between GPLv2 and GPLv3 is the patent section. This 
has caused some concerns in the past when a stakeholder want to 
contribute to Xen Project.

While looking through at previous discussion, I found the original 
discussion [1] which contains a lot more details.

The limit was agreed and discussed between him and Julien and
I agree with them (if any more views were required).

Not quite sure if your mail was to request an other maintainer to
confirm but done anyway.

I don't expect it was intended to default PVH Dom0 to "no assist" mode.
Introduce command line (sub-)options allowing to suppress enabling of
the assists, paralleling the guest config settings for DomU, but restore
the defaulting to "enabled".

Besides the issue caused here (the manifestation of which appears to
correlate with the other fallout Andrew is trying to deal with) I'm
observing further warnings, but I guess these have been there for some
time (perhaps forever): When parsing AML and encountering the objects
describing the CPUs, Linux would find entries with the original APIC
IDs. If those don't match the ones we assign in pvh_setup_acpi_madt(),
the kernel will wrongly consider the entries to describe further CPUs,
which it therefore would deem hot-pluggable. This again results in
warnings, this time "NR_CPUS/possible_cpus limit of ... reached".

I was wondering about that too, but if I'm not mistaken the change you
suggest is the opposite of what would be apparently safe there (against
overrunning buffers). Hence it may take more than just the comparison
type to be modified.

Besides being confusing this depends on the order of checks in xen.h.

At the very least you will want to #undef the auxiliary define as soon
as practically possible.

But I think a different solution will want finding. Did you check what
the #include is needed for, really? I've glanced through the file
without being able to spot anything ... After all this is a build tool,
which generally can't correctly use many of the things declared in the
header.

I'm firmly against adding such a comment in a public header, the more
that it's misleading: Cross-building of Xen, for example, works quite
fine. The issue is limited to HOSTCC != CC (or yet more precisely the
target architecture of each), afaict.

I understand the theory and in general I am not in favor of restricting 
a limit without any data. However, here, I think we have all the data 
necessary that would justify the limit.

In order to use event channels, a guest needs to know which PPI is used 
to notify the guest.

Until recently, we didn't expose the node to dom0less domUs (this was 
introduced when adding support for PV devices). So a guest couldn't 
discover that event channels are used. That said, if the guest figured 
out the PPI (the value can be guessed) then it could potentially use the 
event channels.

However, for Xen on Arm, we are not supporting any guest that don't use 
the firmware tables (e.g. device tree/ACPI). So for such use case, I 
don't care if it breaks because they are relying on unstable information.

What I care about is any user that follow the rules. We only started to 
advertise Xen via Device-Tree to dom0less domUs after 4.16. So I think 
this is fine to restrict the limit now because we haven't released 4.17 yet.

Regarding the default limit, I think it is better to stay consistent 
with libxl and also use 1023. If an admin wants more event channels, 
then we could introduce per-domain property to overwrite the default.

It should not be too difficult to add, but I don't think this is a must.
So I will let Rahul to decide whether he has time to add it.

Cheers,

As stated in the comment after the commit message, this is not a good
solution but an hack.

Now I do not completely agree here, the tool is not really the problem
but the headers are. There is not such an issue on arm.

The tool needs at least:
HVM_MAX_VCPUS
XEN_ACPI_CPU_MAP
XEN_ACPI_CPU_MAP_LEN
XEN_ACPI_GPE0_CPUHP_BIT

Which are defined in arch-x86/xen.h and hvm_info_table.h.

I am not quite sure how to get those without the current include

Point was the todo was more to show where the issue is coming from.
I am really ok to remove this.

Well - the issue is the tool depending on these headers.

Then why does the tool include xen/arch-arm.h for Arm64?

1) Move those #define-s to a standalone header, which the ones
currently defining them would simply include. The tool would then
include _only_ this one header.

2) Seddery on the headers, producing a local one to be used by the
tool.

Where possible I'm all for it.

Yet XEN_ACPI_CPU_MAP_LEN drives from HVM_MAX_VCPUS.

Well - that's the only thing we talk about here. Building target code
is fine to use the headers. Building code to run on the build system
is where the headers should not be used.

> How about moving those to a xen-acpi.h header and include that one in xen.h ?

In principle okay, if there wasn't the need for HVM_MAX_VCPUS. With a
suitable comment it may be okay to live there. I'd be curious what
others think.

> Other solution as those are only used in mk_dsdt, I could just define them there …

Please let's try hard to avoid doing so.

Why?

At first I was surprised you get away there without including xen.h -
this may change at any time, as soon as you grow a dependency.

But then the inclusion by arch-x86/xen.h looks suspicious, since xen.h
itself includes arch-x86/xen.h (first thing), so unless I'm missing
something arch-x86/xen.h can't really have a dependency on xen.h. So
maybe in the short term you could get away with removing that include
as a "fix"?

Hi all,

I changed the subject to reflect the discussion and moved George to
"to:" to get his attention.

Also, if we are going to make any chances as described below, I think
they should be a separate series from the SPDX series.

I agree with Julien. Also, I don't think that having GPLv2-or-later on a
few source files is of benefit to anyone (if Xen was GPLv2-or-later as a
whole it would be a different discussion).

Moving from GPLv2-or-later to GPLv2-only is not a relicense. The "or
later" statement is not part of the license itself. It would be limiting
the choice of license to a subset of what is currently allowed: i.e.
from [GPLv2,GPLv3] to [GPLv2]. I don't think we need approval from the
original authors from that.

The original authors already stated: "my code can be either under GPLv2
or GPLv3". Now we are only offering it under GPLv2. Users can still get
the older version from a past Xen release under GPLv3 if they want to.

So I think we can drop "or later" any time as long as the maintainers
agree.

George, do you agree with the above?

Also gets a second look from others who may have an opinion on the topic.

I second what is after the comma.  Adding SPDX tags and changing files
from GPLv2+ to GPLv2-only are distinct tasks and should be kept separate.

I disagree here.  Having GPLv2+ on a few files hints at the contributor
community's views, though one must exercise care.

Notably if 50% of contributors prefer GPLv2+ less than 10% of files are
likely to be marked GPLv2+.  The reason being GPLv3 didn't exist until
2006 and a single GPLv2-only contributor would cause shared files to be
stuck as GPLv2-only.

So there could be a majority who prefer GPLv2+, just too many existing
files are GPLv2-only.

I'm not an expert, but this matches my understanding as a (near-trivial)
contributor.


I'm not a significant contrbutor, but let it be hereby known my portions
are available under GPLv2+.

FWIW, I hit this issue twice already in this week CI run, while it never
happened before. The difference compared to previous run is Linux
5.15.57 vs 5.15.61. The latter reports persistent grants disabled. The
only related commits I see there are three commits indeed related to
persistent grants:

  c98e956ef489 xen-blkfront: Apply 'feature_persistent' parameter when conn=
ect
  ef26b5d530d4 xen-blkback: Apply 'feature_persistent' parameter when conne=
ct
  7304be4c985d xen-blkback: fix persistent grants negotiation

But none of the commit messages suggests intentional disabling it
without explicit request for doing so. I did not requested disabling it
in toolstack (although I have set backend as "trusted" - XSA-403).
I have confirmed it's the frontend version that matters. Running older
frontend kernel with 5.15.61 backend results in persistent grants
enabled (and both frontend and backend xenstore "feature-persistent"
entries are "1" in this case).

Why would that be? We don't even have CET related defines for XCR0, so
we don't enable the states in XSS. And I don't see why we would. Even
for other XSTATE-managed but not XSTATE-enabled features we could
clear the respective bits around the CPUID invocation (just like we
may need to set some in XSS). We'd be in trouble only for any XSTATE-
enabled feature that we make use of ourselves.

Hmm, yes, that's certainly wording worth of improving (regardless of any
addition to the general paragraph).

Subject: [PATCH 0/2] Introduce reserved heap
Date: Wed, 24 Aug 2022 07:31:25 +0000
Message-Id: <20220824073127.16762-1-Henry.Wang@arm.com>
X-Mailer: git-send-email 2.17.1

The reserved heap, or statically configured heap, refers to parts
of RAM reserved in the beginning for heap. Like the static memory
allocation, such reserved heap regions are reserved by configuration
in the device tree using physical address ranges.

This feature is useful to run Xen on Arm MPU systems, where only a
finite number of memory protection regions are available. The limited
number of protection regions places requirement on planning the use of
MPU protection regions and one or more MPU protection regions needs to
be reserved only for heap.

The first patch introduces the reserved heap and the device tree parsing
code. The second patch adds the implementation of the reserved heap
pages handling in boot and heap allocator for Arm.

Changes from RFC to v1:
- Rename the terminology to reserved heap.
- Rebase on top of latest `setup_mm()` changes.
- Added Arm32 logic in `setup_mm()`.

Subject: [PATCH 2/2] xen/arm: Handle reserved heap pages in boot and heap allocator
Date: Wed, 24 Aug 2022 07:31:27 +0000
Message-Id: <20220824073127.16762-3-Henry.Wang@arm.com>

This commit firstly adds a global variable `reserved_heap`.
This newly introduced global variable is set at the device tree
parsing time if the reserved heap ranges are defined in the device
tree chosen node.

For Arm32, In `setup_mm`, if the reserved heap is enabled, we use
the reserved heap region for both domheap and xenheap allocation.

For Arm64, In `setup_mm`, if the reserved heap is enabled and used,
we make sure that only these reserved heap pages are added to the
boot allocator. These reserved heap pages in the boot allocator are
added to the heap allocator at `end_boot_allocator()`.

If the reserved heap is disabled, we stick to current page allocation
strategy at boot time.

Also, take the chance to correct a "double not" print in Arm32
`setup_mm()`.

---
With reserved heap enabled, for Arm64, naming of global variables such
as `xenheap_mfn_start` and `xenheap_mfn_end` seems to be ambiguous,
wondering if we should rename these variables.
---
Changes from RFC to v1:
- Rebase on top of latest `setup_mm()` changes.
- Added Arm32 logic in `setup_mm()`.

Subject: [PATCH 1/2] docs, xen/arm: Introduce reserved heap memory
Date: Wed, 24 Aug 2022 07:31:26 +0000
Message-Id: <20220824073127.16762-2-Henry.Wang@arm.com>
X-Mailer: git-send-email 2.17.1
In-Reply-To: <20220824073127.16762-1-Henry.Wang@arm.com>

This commit introduces the reserved heap memory, which is parts of RAM
reserved in the beginning of the boot time for heap.

A new boolean field `xen_heap` in `struct membank` is added to store the
configuration telling if the memory bank is reserved as heap through
`xen,static-mem` property in device tree `chosen` node.

Also, this commit introduces the logic to parse the reserved heap
configuation in device tree by reusing the device tree entry definition
of the static memory allocation feature:

- Add a boolean parameter `xen_heap` to `device_tree_get_meminfo` to
reflect whether the memory bank is reserved as heap.

- Use `device_tree_get_meminfo` to parse the reserved heap configuation
in `chosen` node of the device tree.

- In order to reuse the function `device_tree_get_meminfo`, the
return type of `process_chosen_node` is changed from void to int.

A documentation section is added, describing the definition of reserved
heap memory and the method of enabling the reserved heap memory through
device tree at boot time.

---
The name of the device tree property was chosen because we want to
reuse as much as the device tree parsing helpers from the static
memory allocation feature, but we would like to hear the upstream
reviewers' opinion about if using "xen,static-heap" is better.
---
Changes from RFC to v1:
- Rename the terminology to reserved heap.

+
+Reserved Heap Memory
+====================
+
+The reserved heap memory (also known as the statically-configured heap) refers
+to parts of RAM reserved in the beginning for heap. The memory is reserved by
+configuration in the device tree using physical address ranges.
+
+The reserved heap memory declared in the device tree defines the memory areas
+that will be reserved to be used exclusively as heap.
+
+- For Arm32, since there can be seperated heaps, the reserved heap will be used
+for both domheap and xenheap.
+- For Arm64, since domheap and xenheap are the same, the defined reserved heap
+areas shall always go to the heap allocator.
+
+The reserved heap memory is an optional feature and can be enabled by adding a
+device tree property in the `chosen` node. Currently, this feature reuses the
+static memory allocation device tree configuration.
+
+The dtb property should look like as follows:
+
+- property name
+
+    "xen,static-mem" (Should be used in the `chosen` node)
+
+- cells
+
+    Specify the start address and the length of the reserved heap memory.
+    The number of cells for the address and the size should be defined
+    using the properties `#xen,static-mem-address-cells` and
+    `#xen,static-mem-size-cells` respectively.
+
+Below is an example on how to specify the reserved heap in device tree:
+
+    / {
+        chosen {
+            #xen,static-mem-address-cells = <0x2>;
+            #xen,static-mem-size-cells = <0x2>;
+            xen,static-mem = <0x0 0x30000000 0x0 0x40000000>;
+        };
+    };
+
+RAM at 0x30000000 of 1G size will be reserved as heap.

Just removing the include is ending up in errors (I tried that first).
I will dig deeper to check if those are possible to solve but some files
including arch-x86/xen.h should actually including xen.h instead and
I think the amount of changes might get a bit bigger.
I will give it a try.

You're referring to it being necessary to explicitly include both headers.
That's not what I'm referring to, though: The tool imo shouldn't include
hvm_info_table.h, and hence the HVM_MAX_VCPUS would need to move as well.

> Including hvm_info_table.h from xen-acpi.h could create include path issues.

Include path issues? Both are / would be public headers. But as said, I
don't think any new header introduced for the purpose at hand should
include _any_ other public header.

Hmm, yes, that's reasonable I guess as far as XEN_ACPI_* go. Of course
HVM_MAX_VCPUS is a different matter.

Requiring them to include another header is, I think, a tolerable form
of breakage, the more that such breakage isn't very likely anyway.

Would be good to add a justification that these helpers will be needed by subsequent patches.
Also I can see that you make use of them only in the last patch so it would be natural to
move this patch right before the one making use of these helpers.

TBH, I think all ASSERT_UNREACHABLE() paths should be accompanied with a 
printk(). This would also allow us to catch issue in production rather 
than in only in debug.

In particular, for the page allocator, I have seen issue that only 
happen very rarely. Although, this seems unlikely in this case.

AFAICT, patch #2 needs some tweak. So I assuming this will need a 
respin. If not, I can possibly handle the change while committing if you 
provide a new version of the commit message.

Cheers,

Hi Juergen,

I understand why we moved from user pages to kernel pages, but I don't
fully understand why we need to make two separate calls to map the
guest memory, i.e. mmap() followed by ioctl(IOCTL_PRIVCMD_MMAPBATCH).

Why aren't we doing all of it from mmap() itself ? I hacked it up to
check on it and it works fine if we do it all from mmap() itself.

Aren't we abusing the Linux userspace ABI here ? As standard userspace
code would expect just mmap() to be enough to map the memory. Yes, the
current user, Xen itself, is adapted to make two calls, but it breaks
as soon as we want to use something that relies on Linux userspace
ABI.

For instance, in our case, where we are looking to create
hypervisor-agnostic virtio backends, the rust-vmm library [1] issues
mmap() only and expects it to work. It doesn't know it is running on a
Xen system, and it shouldn't know that as well.

Thanks.

Looking at other config options, we usually have <feature>=BOOLEAN (without _enabled), so
I would just stick to "ffa". This would require changes in other places accordingly.

Should be:
"Currently only a small subset of the FF-A specification is supported"

Applying this patch results in a failure here so you need to rebase it on top of latest status.

Also, FWICS (can be checked by the toolstack maintainers) you are missing the required
changes in:
 - tools/golang/xenlight/helpers.gen.go
 - tools/golang/xenlight/types.gen.go
 - tools/ocaml/libs/xc/xenctrl.ml
 - tools/ocaml/libs/xc/xenctrl.mli

That could be a first step. I still think a message like Penny has added

Subject: [PATCH] xen: let ASSERT_UNREACHABLE() WARN() in non-debug builds
Date: Wed, 24 Aug 2022 12:22:25 +0200
Message-Id: <20220824102225.11431-1-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Hitting an ASSERT_UNREACHABLE() is always wrong, so even in production
builds a warning seems to be appropriate when hitting one.

In order not to flood the console in reproducible cases, introduce
WARN_ONCE() to be used in this case.

Signed-off-by: Juergen Gross <jgross@suse.com>

Notice for the release manager: this patch isn't really urgent for the
4.17 release, OTOH it is adding probably useful debug information for
the unlikely case of hitting an ASSERT_UNREACHABLE(). The risk for
taking the patch should be rather low, but you have the last saying,
of course.

I disagree, for two reasons: This violates the implication of NDEBUG
meaning ASSERT() and friends expand to no actual code. Plus if doing so
for ASSERT_UNREACHABLE(), why would we not do the same for ASSERT()?
There's a reason we have ASSERT() and friends and, independently,
WARN_ON() / BUG_ON() et al.

I agree with Jan here, this is introducing code in ASSERT which is not the =
intention
and will end up with dead code in production mode.

In NDEBUG those should appear.

If something is needed or we think there could be a situation where this is=
 reachable,
then the code should be modified to use something else then ASSERT[_UNREACH=
ABLE]().

If you want more than just the line number, use ASSERT() with a meaningful
expression. That'll be easily a fair replacement for a separate printk().
And no, as said in reply to Jürgen's patch, ASSERT() and friends should
not leave any traces in non-debug builds. If you want such, use WARN_ON()
or BUG_ON().

Subject: [PATCH 2/4] x86/hvmloader: Don't build as PIC/PIE
Date: Wed, 24 Aug 2022 11:59:13 +0100
Message-ID: <20220824105915.32127-3-andrew.cooper3@citrix.com>
X-Mailer: git-send-email 2.11.0
In-Reply-To: <20220824105915.32127-1-andrew.cooper3@citrix.com>
References: <20220824105915.32127-1-andrew.cooper3@citrix.com>
MIME-Version: 1.0
Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: 8bit

HVMLoader is not relocatable in memory, and 32bit PIC code has a large
overhead.  Build it as non-relocatable.

Bloat-o-meter reports a net:
  add/remove: 0/0 grow/shrink: 3/107 up/down: 14/-3370 (-3356)

No functional change.

Subject: [PATCH 4/4] x86/hvmloader: Move various helpers to being static inlines
Date: Wed, 24 Aug 2022 11:59:15 +0100
Message-ID: <20220824105915.32127-5-andrew.cooper3@citrix.com>
X-Mailer: git-send-email 2.11.0
In-Reply-To: <20220824105915.32127-1-andrew.cooper3@citrix.com>

The IO port, MSR, IO-APIC and LAPIC accessors compile typically to single or
pairs of instructions, which is less overhead than even the stack manipulation
to call the helpers.

Move the implementations from util.c to being static inlines in util.h

In addition, turn ioapic_base_address into a constant as it is never modified
from 0xfec00000 (substantially shrinks the IO-APIC logic), and make use of the
"A" constraint for WRMSR/RDMSR like we already do for RDSTC.

Bloat-o-meter reports a net:
  add/remove: 0/13 grow/shrink: 1/19 up/down: 6/-743 (-737)

No functional change.

 * Use MOV CR instead of LMSW.  LMSW has no decode assist at all on AMD CPUs,
   forcing us to fully emulate the instruction.
 * Use __attribute__((used)) to fix the comment about ap_start().
 * Have ap_start() perform a self-INIT for APs, rather than having boot_cpu()
   do it.  This is marginally more parallel, and reduces the amount of remote
   vCPU management that Xen has to do on behalf of the guest.

All encountered while debugging a regression in Xen 4.17.

They're all very trivial, and addressing low hanging fruit.

Andrew Cooper (4):
  x86/hvmloader: SMP improvements
  x86/hvmloader: Don't build as PIC/PIE
  x86/hvmloader: Don't override stddef.h
  x86/hvmloader: Move various helpers to being static inlines

Since c/s 73b13705af7c ("firmware: provide a stand alone set of headers"),
we've had an implementation of offsetof() which isn't undefined behaviour.
Actually use it.

As I understand it the MMAPBATCH ioctl is being treated like every other
hypercall proxy through the ioctl interface. Which makes sense from the
point of view of having a consistent interface to the hypervisor but not
from point of view of providing a consistent userspace interface for
mapping memory which doesn't care about the hypervisor details.

The privcmd_mmapbatch_v2 interface is slightly richer than what you
could expose via mmap() because it allows the handling of partial
mappings with what I presume is a per-page *err array. If you issued the
hypercall directly from the mmap() and one of the pages wasn't mapped by
the hypervisor you would have to unwind everything before returning
EFAULT to the user.

I'm unsure what is meant by safe memory here. privcmd_buf_mmap() looks
like it just allocates a bunch of GFP_KERNEL pages rather than
interacting with the hypervisor directly. Are these the same pages that
get used when you eventually call privcmd_ioctl_mmap_batch()?

The fact that /dev/xen/hypercall is specified by xen_privcmdbuf_dev is a
little confusing TBH.

Anyway the goal here is to provide a non-xen aware userspace with
standard userspace API to access the guests memory. Perhaps messing
around with the semantics of the /dev/xen/[hypercall|privcmd] devices
nodes is too confusing.

Maybe we could instead:

 1. Have the Xen aware VMM ask to make the guests memory visible to the
    host kernels address space.
 2. When this is done explicitly create a device node to represent it (/dev=
/xen/dom-%d-mem?)
 3. Pass this new device to the non-Xen aware userspace which uses the
    standard mmap() call to make the kernel pages visible to userspace

Does that make sense?

Aren't the hypercall buffers all internal to the kernel/hypervisor
interface or are you talking about the ioctl contents?

Any suggestion where ?
The more I dig, the more I find that everything is including xen.h and goin=
g round.
Arch-x86_*.h headers are including arch-x86/xen.h including xen.h

For now I can create a arch-x86/xen-acpi.h and move there the XEN_ACPI_*
definitions and include that one instead in mk_dsdt.h.
The change will be small and should not have much impact.

Modifying HVM_MAX_VCPUS is not per say needed and I think would not be
enough to make the situation cleaner.

Then if you are ok with it, I will just submit the xen-acpi.h creation patc=
h and fix
mk_dsdt compilation for x86 on arm.

The rest would require more thinking and I do not think it should be done n=
ow.

Can you confirm you agree ?

While Arm64 does so uniformly, for Arm32 only strchr() currently handles
this properly. Add the necessary conversion also to strrchr(), memchr(),
and memset().

As to the placement in memset(): Putting the new insn at the beginning
of the function is apparently deemed more "obvious". It could be placed
later, as the code reachable without ever making it to the "1" label
only ever does byte stores.

v2: For memset() use the "more obvious" adjustment.

You can't use "xen,enhanced" without dom0. In fact, you will end up to 
dereference NULL in alloc_xenstore_evtchn(). That's because 
"xen,enhanced" means the domain will be able to use Xenstored.

Now if you want to support your feature without a dom0. Then I think we 
want to introduce an option which would be the same as "xen,enhanced" 
but doesn't expose Xenstored.

Cheers,

Not really, no. That's why I said this is the one part where improvement
is more difficult. Otoh hvm_info_table.h is self-contained right now and
doesn't even produce potentially misleading struct layout for the one
struct it declares. So perhaps not too bad if left alone.

Indeed, all quite odd.

Almost - I don't like xen-acpi.h as the name of the new header. Just
arch-x86/acpi.h would likely be too generic, so I'd like to suggest
arch-x86/hvm-acpi.h or arch-x86/guest-acpi.h. I have a slight
preference to the latter, because "hvm" also covers "pvh", yet PVH
Dom0 is dealt with entirely differently ACPI-wise. Plus "guest"
isn't misleading as to PV, because PV guests don't have ACPI anyway.

Subject: [RFC PATCH v1 0/2] Add a new acquire resource to query vcpu statistics
Date: Wed, 24 Aug 2022 15:27:29 +0200
Message-Id: <cover.1661330065.git.matias.vara@vates.fr>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Hello all,

The purpose of this RFC is to get feedback about a new acquire resource that
exposes vcpu statistics for a given domain. The current mechanism to get those
statistics is by querying the hypervisor. This mechanism relies on a hypercall
and holds the domctl spinlock during its execution. When a pv tool like xcp-rrdd
periodically samples these counters, it ends up affecting other paths that share
that spinlock. By using acquire resources, the pv tool only requires a few
hypercalls to set the shared memory region and samples are got without issuing
any other hypercall. The original idea has been suggested by Andrew Cooper to
which I have been discussing about how to implement the current PoC. You can
find the RFC patch series at [1]. The series is rebased on top of stable-4.15.

I am currently a bit blocked on 1) what to expose and 2) how to expose it. For
1), I decided to expose what xcp-rrdd is querying, e.g., XEN_DOMCTL_getvcpuinfo.
More precisely, xcp-rrd gets runstate.time[RUNSTATE_running]. This is a uint64_t
counter. However, the time spent in other states may be interesting too.
Regarding 2), I am not sure if simply using an array of uint64_t is enough or if
a different interface should be exposed. The remaining question is when to get
new values. For the moment, I am updating this counter during
vcpu_runstate_change().

The current series includes a simple pv tool that shows how this new interface is
used. This tool maps the counter and periodically samples it.

Any feedback/help would be appreciated.

Thanks, Matias.

[1] https://github.com/MatiasVara/xen/tree/feature_stats

Changes in v1:
- rework how the resource is allocated and released
- rework when the resource is allocated that happens only when the resource is
  requested 
- rework the structure shared between the tool and Xen to make it extensible to
  new counters and declare it in a public header

There are still the following questions:
   - consumer may fetch inconsistency data
   - resource shall be released when there are no more readers otherwise we keep
     updating it during a hot path
   - one frame can host up to 512 vcpus. Should I check to this limit when
     updating? Should it be possible to allocate more than one frame for vcpu
     counters?

Subject: [RFC PATCH v1 1/2] xen/memory : Add a stats_table resource type
Date: Wed, 24 Aug 2022 15:27:30 +0200
Message-Id: <c36dc94e11dc8529f489bbbd4e8079b10f298625.1661330065.git.matias.vara@vates.fr>

This commit proposes a new mechanism to query the RUNSTATE_running counter for
a given vcpu from a dom0 userspace application. This commit proposes to expose
that counter by using the acquire_resource interface. The current mechanism
relies on the XEN_DOMCTL_getvcpuinfo and holds a single global domctl_lock for
the entire hypercall; and iterate over every vcpu in the system for every
update thus impacting operations that share that lock.

This commit proposes to expose vcpu RUNSTATE_running via the
xenforeignmemory interface thus preventing to issue the hypercall and holding
the lock. For that purpose, a new resource type named stats_table is added. The
first frame of this resource stores per-vcpu counters. The frame has one entry
of type struct vcpu_stats per vcpu. The allocation of this frame only happens
if the resource is requested. The frame is released after the domain is
destroyed.

Note that the updating of this counter is in a hot path, thus, in this commit,
copying only happens if it is specifically required.

Note that the exposed structure is extensible in two ways. First, the structure
vcpu_stats can be extended with new per-vcpu counters while it fits in a frame.
Second, new frames can be added in case new counters are required.

Signed-off-by: Matias Ezequiel Vara Larsen <matias.vara@vates.fr>
---
Changes in v1:
- rework the allocation and releasing of the frames
- use the zero frame for per-vcpu counters that are listed as an array
- allocate vcpu stats frames only when the resource is requested
- rewrite commit message
- add the vcpu_stats structure to keep per-vcpu counters
- add the shared_vcpustatspage to keep an array of per-vcpu counters for a
  given domain
- declare the structures in a public header 
- define the vcpustats_page in the domain structure

Subject: [RFC PATCH v1 2/2] tools/misc: Add xen-vcpus-stats tool
Date: Wed, 24 Aug 2022 15:27:31 +0200
Message-Id: <c17fc1382cdf0b5975573759c790eed5d4a16192.1661330065.git.matias.vara@vates.fr>
X-Mailer: git-send-email 2.25.1
In-Reply-To: <cover.1661330065.git.matias.vara@vates.fr>
References: <cover.1661330065.git.matias.vara@vates.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Add a demostration tool that uses the stats_table resource to
query vcpus' RUNSTATE_running counter for a DomU.

Signed-off-by: Matias Ezequiel Vara Larsen <matias.vara@vates.fr>
---
Changes in v1:
- change the name of the tool to xen-vcpus-stats
- set command line parameters in the same order that are passed
- remove header libs.h
- build by default
- remove errno, strerrno, "\n", and identation
- use errx when errno is not needed
- address better the number of pages requested and error msgs
- use the shared_vcpustatspage_t structure
- use the correct frame id when requesting the resource

Maybe "there are" instead of "there can be" as we do define for Arm32:
#define CONFIG_SEPARATE_XENHEAP 1
and I do not think we have some flexibility to change this.

Instead of writing "since domheap and xenheap are the same" maybe it'd be better to write:
"For Arm64, as there is a single heap..."

You do not really need to change the return type of this function.
Currently process_chosen_node just returns on an error condition so you could do the same.

address_cells and size_cells cannot be negative so you could just check if there are 0.

This change breaks the current behavior and will result in triggering the printk in early_scan_node for parsing failure.
Is this intended? If so, you could mention this in the commit msg.

Backport Linux commit dc898eb84b25c39ea46f28c48a169bdbd0e2c7e0
iommu/arm-smmu-v3: Fix l1 stream table size in the error message

Original commit message:
    iommu/arm-smmu-v3: Fix l1 stream table size in the error message
    The actual size of level-1 stream table is l1size. This looks like
    an oversight on commit d2e88e7c081ef ("iommu/arm-smmu: Fix LOG2SIZE
    setting for 2-level stream tables") which forgot to update the @size
    in error message as well.

    As memory allocation failure is already bad enough, nothing worse
    would happen. But let's be careful.

    While harmless, they are incorrect and could hide actual errors during

Backport Linux commit 86d2d9214880c1879cb0ff466cce2fcd9c853e44
"iommu/arm-smmu-v3: Remove the page 1 fixup"

Original commit message:
    iommu/arm-smmu-v3: Remove the page 1 fixup

    Since we now keep track of page 1 via a separate pointer that
    already encapsulates aliasing to page 0 as necessary, we can remove
    the clunky fixup routine and simply use the relevant bases directly.
    The current architecture spec (IHI0070D.a) defines
    SMMU_{EVENTQ,PRIQ}_{PROD,CONS} as offsets relative to page 1, so the
    cleanup represents a little bit of convergence as well as just
    lines of code saved.

Original commit message:
    iommu/arm-smmu-v3: Remove the unused fields for PREFETCH_CONFIG
    command

    Per SMMUv3 spec, there is no Size and Addr field in the
    PREFETCH_CONFIG command and they're not used by the driver.
    Remove them.

    We can add them back if we're going to use PREFETCH_ADDR in the
    future.

"iommu/arm-smmu-v3: Avoid open coded arithmetic in memory allocation"

Original commit message:
    iommu/arm-smmu-v3: Avoid open coded arithmetic in memory allocation
    kmalloc_array()/kcalloc() should be used to avoid potential overflow
    when a multiplication is needed to compute the size of the requested
    memory.

    So turn a devm_kzalloc()+explicit size computation into an
    equivalent devm_kcalloc().

Subject: [PATCH 04/10] xen/arm: smmuv3: Move definitions to a header
Date: Wed, 24 Aug 2022 14:53:08 +0100
Message-Id: <e8ad3eed5474f2f09ef4fcca1ce0d1a669baca2b.1661331102.git.rahul.singh@arm.com>
X-Mailer: git-send-email 2.25.1
In-Reply-To: <cover.1661331102.git.rahul.singh@arm.com>
References: <cover.1661331102.git.rahul.singh@arm.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Allow sharing structure definitions with the upcoming virtual
smmuv3 support for Arm SMMUv3, by moving them to a separate header.

Code was imported from Linux source code so keep the Linux syntax.

Backport Linux commit a76a37777f2c936b1f046bfc0c5982c958b16bfe
"Ensure queue is read after updating prod pointer"

Original commit message:
    iommu/arm-smmu-v3: Ensure queue is read after updating prod pointer
    Reading the 'prod' MMIO register in order to determine whether or
    not there is valid data beyond 'cons' for a given queue does not
    provide sufficient dependency ordering, as the resulting access is
    address dependent only on 'cons' and can therefore be speculated
    ahead of time, potentially allowing stale data to be read by the
    CPU.

    Use readl() instead of readl_relaxed() when updating the shadow copy
    of the 'prod' pointer, so that all speculated memory reads from the
    corresponding queue can occur only from valid slots.

    [will: Use readl() instead of explicit barrier. Update 'cons' side to match.]

The problem is wider than that, because earlier errors would also
lead to "out" (e.g. after copy_from_user() failed). Plus I guess
unlock_pages() shouldn't be called at all (or with its 2nd arg set
to zero) before lock_pages() was actually called. But I agree with
the further analysis below. Would you mind sending a patch?

Hi,

I am porting xen hypervisor on rpi4 with yocto kirkstone sources. Followed
the basic steps to build xen-image-minimal & xen-guest-image-minimal. I
could flash sd card with xen minimal image & could see dom0 up. I copied
"Image", "xen-guest-image-minimal" .ext3 file & guest.cfg to "/home/root".
After that created a bridge with below step:

killall -SIGUSR2 udhcpc
brctl addbr xenbr0
brctl addif xenbr0 eth0
killall udhcpc
udhcpc -R -b -p /var/run/udhcpc.xenbr0.pid -i xenbr0

Could see the xenbr0 interface up.
After that while mounting the guest file system it shows no such file or
directory but the file is already there.

Hmm, yes, read-modify-write should probably have been used from
the beginning, irrespective of using 286 or 386 insns.

Is there a reason you remove this barrier but not the one in boot_cpu()?

Are we intending to guarantee going forward that the BSP always has
APIC ID zero?

The use of the function for the BSP is questionable anyway. What is
really needed is the call to cacheattr_init(). I'm inclined to
suggest to move to something like

void smp_initialise(void)
{
    unsigned int i, nr_cpus = hvm_info->nr_vcpus;

    cacheattr_init();

    if ( nr_cpus <= 1 )
        return;

    memcpy((void *)AP_BOOT_EIP, ap_boot_start, ap_boot_end - ap_boot_start);

    printf("Multiprocessor initialisation:\n");
    for ( i = 1; i < nr_cpus; i++ )
        boot_cpu(i);
}

thus eliminating bogus output when there's just one vCPU. 

Then the function here can become noreturn (which I was about to suggest
until spotting that for the BSP the function actually does return).

Can't you use APIC_DEST_SELF now, avoiding the need to fiddle
with ICR2?

Subject: [PATCH] xen/privcmd: fix error exit of privcmd_ioctl_dm_op()

The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.

Fix that by calling unlock_pages only if lock_pages() was at least
partially successful.

Subject: [PATCH v1 0/4] Yocto Gitlab CI
Date: Wed, 24 Aug 2022 15:57:16 +0100
Message-Id: <cover.1661352827.git.bertrand.marquis@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

This patch series is a first attempt to check if we could use Yocto in
gitlab ci to build and run xen on qemu for arm, arm64 and x86.

The first patch is making sure build-yocto.sh is not catched by
gitignore.

The second patch is creating a container with all elements required to
build Yocto, a checkout of the yocto layers required and an helper
script to build and run xen on qemu with yocto.

The third patch is creating containers with a first build of yocto done
so that susbsequent build with those containers would only rebuild what
was changed and take the rest from the cache.

The fourth patch is adding a way to easily clean locally created
containers.

This is is mainly for discussion and sharing as there are still some
issues/problem to solve:
- building the qemu* containers can take several hours depending on the
  network bandwith and computing power of the machine where those are
  created
- produced containers containing the cache have a size between 8 and
  12GB depending on the architecture. We might need to store the build
  cache somewhere else to reduce the size. If we choose to have one
  single image, the needed size is around 20GB and we need up to 40GB
  during the build, which is why I splitted them.
- during the build and run, we use a bit more then 20GB of disk which is
  over the allowed size in gitlab

Once all problems passed, this can be used to build and run dom0 on qemu
with a modified Xen on the 3 archs in less than 10 minutes.

This has been tested on a x86 host machine and on an arm host machine
(with mk_dsdt.c fix).

Bertrand Marquis (4):
  automation: Only filter build-*/ in gitignore
  automation: Add elements for Yocto test and run
  automation: Add yocto containers with cache
  automation: Add a clean rule for containers

Create yocto containers for kirkstone with a builder step to fill the
yocto cache by running the build script once.
Those containers depend on the kirkstone.dockerfile container to be
created and use it as base image.

To run a build test on one image the following command must be called
inside the container:
build-yocto.sh --xen-dir=XENSRC TARGET where
- XENSRC is the directory where xen sources are available in the
container
- TARGET is the build target (qemuarm64, qemuarm or qemux86_64)

In case of error, the script will return an error code and the logs will
be in /home/docker-build/logs.

!!!
The build of each container can take several hours depending on the
network bandwith (for downloading all sources) and the amount of
computing power on the machine where the docker images are created.
!!!

Subject: [PATCH v1 2/4] automation: Add elements for Yocto test and run
Date: Wed, 24 Aug 2022 15:57:18 +0100

Add a container suitable to run yocto kirkstone build based on ubuntu
22.04. It contains all packages required by Yocto and a checkout of the
layers required to build Xen with Yocto.

Add a build script to build and run xen on qemu using Yocto.
The script supports arm32, arm64 and x86_64 and checks that dom0 is
properly booting. At this stage this does not run any guest on top of
dom0.

The build script is currently in the same directory than the docker
files so that it can be included directly in the image. This is required
for the next step which creates images with an initial cache content to
speed up testing.

Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
---
Changes in v1:
- add --image command line argument to build-yocto.sh to allow building
something different than xen-image-minimal.
- modify dockerfile to have one layer per line and make it easier to add
other. I kept the for loop to keep the number of docker steps lower
- update commit message to warn that no guest are tested.
- fix build-yocto script to properly return with an error if expect
script ends up in timeout or EOF.

We have a tag for this (see Origin). If you use it, then...

You don't need to add "original commit message" here and the content is 
exactly the same.

AFAICT, you didn't make any change to this patch. So the "From:" should 
still be from Zenghui Yu. For an example how to do backport, see
9c432b876bf518866d431bda73f2be1250f688eb "x86/mwait-idle: add SPR support".

Also, it would be good to clarify whether they are clean backport and 
required some changes (other than context changes). I assume they are 
clean backports?

The same applies for all the patches in this series.

Hi,

I haven't seen this feature posted yet. So I can't tell how this will 
allow sharing. I guess you will introduce a new file?

In any case, I would suggest to either delay this patch until you send 
your work or find a different reason to split it (I can't think of one yet).

Cheers,

Subject: [PATCH v1] x86/public: move XEN_ACPI_ in a new header
Date: Wed, 24 Aug 2022 16:29:45 +0100
Message-Id: <b79164d207113af05417536438b786850875edb1.1661353272.git.bertrand.marquis@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

When Xen is compiled for x86 on an arm machine, libacpi build is failing
due to a wrong include path:
- arch-x86/xen.h includes xen.h
- xen.h includes arch-arm.h (as __i386__ and __x86_64__ are not defined
but arm ones are).

To solve this issue move XEN_ACPI_ definitions in a new header
guest-acpi.h that can be included cleanly by mk_dsdt.c

Previous users needing any of the XEN_ACPI_ definitions will now need to
include arch-x86/guest-acpi.h instead of arch-x86/xen.h

Fixes: d6ac8e22c7c5 ("acpi/x86: define ACPI IO registers for PVH
guests")
Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
---
The x86 header is including ../xen.h before the ifndef/define so that it
gets included back by xen.h. This is wrongly making the assumption that
we are using an x86 compiler which is not the case when building the
tools for x86 on an arm host.
Moving the definitions to an independent header is making things cleaner
but some might need to include a new header but the risk is low.

For the release manager:
- risk: very low, the definitions moved are only used in mk_dsdt and
external users would just have to include the new header.
- advantage: we can now compile xen for x86 on arm build machines
---
Changes in v1:
- was "libacpi: Fix cross building x86 on arm"
- move XEN_ACPI_ definitions in a new header guest-acpi.h
- adapt mk_dsdt.c
- remove todo in public header

Yes. For two reasons:
  1) It is muddying the meaning of "xen,enhanced". In particular a user 
may not realize that Xenstore is not available if dom0 is not present.
  2) It would be more complicated to handle the case where Xenstored 
lives in a non-dom0 domain. I am not aware of anyone wanting this on Arm 
yet, but I don't want to close the door.

So if you want to support create "xen,xen" without all the rest. Then I 
think we need a different property value. I don't have a good suggestion 
for the name.

Cheers,

We didn't ignore them - the initial version of the xen-vhost-master
binary was built with the rust and linking to the Xen libraries. We are
however in the process of moving to more pure rust (with the xen-sys
crate being a pure rust ioctl/hypercall wrapper).

However I was under the impression there where two classes of
hypercalls. ABI stable ones which won't change (which is all we are
planning to implement for xen-sys) and non-stable ABIs which would need
mediating by the xen libs. We are hoping we can do all of VirtIO with
just the stable ABI.

We are not talking about doing an end-run around the Xen architecture.
The guest still has to instruct the hypervisor to grant access to its
memory. Currently this is a global thing (i.e. whole address space or
nothing) but obviously more fine grained grants can be done on a
transaction by transaction basis although we are exploring more
efficient mechanisms for this (shared pools and carve outs).

This does raise questions for the mmap interface though - each
individually granted region would need to be mapped into the dom0
userspace virtual address space or perhaps a new flag for mmap() so we
can map the whole address space but expect SIGBUS faults if we access
something that hasn't been granted.

Hi Bertrand,

Thanks for your response!

I builded the guest image on yocto kirkstone source which has FSTYPE ext3.
Guest image generated is xen-guest-image-minimal-raspberrypi4-64.ext3.
Below is the content of guest.cfg file

*   kernel =3D "/home/root/Image" *
*   cmdline =3D "console=3Dhvc0 earlyprintk=3Dxen sync_console root=3D/dev/=
xvda" *
*   memory =3D "256" *
*   name =3D "guest1" *
*   vcpus =3D 1 *
*   serial=3D"pty" *
*   disk =3D [ 'phy:/dev/loop0,xvda,w' ] *
*   vif=3D[ 'mac=3D00:11:22:66:88:22,bridge=3Dxenbr0,type=3Dnetfront', ]*

I am trying to mount xen-guest-image-minimal-raspberrypi4-64.ext3 to a
virtual device & then will run the guest VM by command "xl create -c
guest.cfg". But facing issue while trying to mount.

Regards,
Vipul Kumar

Why do you want to mount the file system ?<br>
<br>
Anyway this is not related to Xen, I guess you could start without xen and =
still not manage to mount the file like that (linux configuration issue ?)<=
br>
<br>
What is the content of you guest.cfg<br>
How do you want to pass the guest root file system ?<br>
<br>
Yocto should actually generate an img file and you could use it by having s=
omething like this in your guest.cfg:<br>
disk=3D[&quot;file:/home/root/guest1.img,xvda,w=E2=80=9D]<br>
<br>
Cheers<br>

Sorry for making the mess, and thank you for the kind report and detailed
explanation of the problem.

Agreed.  So, I think the issue comes from the fact that we are using one field,
which was a place for saving only the negotiation result, for yet another
purpose: caching of the parameter value.  As a result, the advertisement, which
should follow only the parameter value, becomes inconsistent.

How about simply adding another field for the caching purpose, so that the
advertisation could be done regardless of the negotiation?  For example:

Subject: [PATCH] Make XEN_FW_EFI_MEM_INFO easier to use
Date: Wed, 24 Aug 2022 17:04:52 -0400
Message-Id: <20220824210452.3089-1-demi@invisiblethingslab.com>
X-Mailer: git-send-email 2.37.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The XEN_FW_EFI_MEM_INFO platform op has very surprising behavior: it
only sets info->mem.size if the initial value was *larger* than the size
of the memory region.  This is not particularly useful and cost me most
of a day of debugging.  It also has some integer overflow problems,
though as the data comes from dom0 or the firmware (both of which are
trusted) these are not security issues.

Fix both of these problems by unconditionally setting the memory region
size and by computing it in a way that is immune to integer overflow.
The new code is slightly longer, but it is much easier to understand and
use.

You don't actually need to mount
xen-guest-image-minimal-raspberrypi4-64.ext3 anywhere to use it to run
your guest VM with "xl create". 

It is enough to do this instead, as Bertrand suggested:

disk=["file:/path/to/file/xen-guest-image-minimal-raspberrypi4-64.ext3,xvda,w"]

No need to call losetup or mount. Just xl create -c.

More answers below.

It looks like either
/home/root/xen-guest-image-minimal-raspberrypi4-64.ext3 doesn't exist or
/dev/loop0 doesn't exist

Thinking more about this, today xen,enhanced has the implication that:

- the guest will get a regular and complete "xen,xen" node in device tree
- xenstore and PV drivers will be available (full Xen interfaces support)

We don't necessarely imply that dom0 is required (from a domU point of
view) but we do imply that xenstore+evtchn+gnttab will be available to
the domU.

Now, static event channels are different. They don't require xenstore
and they don't require gnttab.

It is as if the current xen,enhanced node actually meant:

  xen,enhanced = "xenstore,gnttab,evtchn";

and now we are only enabling a subset:

  xen,enhanced = "evtchn";

Is that a correct understanding?


If so, we can clarify that:

  xen,enhanced;

it is a convenient shortend for:

  xen,enhanced = "xenstore,gnttab,evtchn";

and that other combinations are also acceptable, e.g.:

  xen,enhanced = "gnttab";
  xen,enhanced = "evtchn";
  xen,enhanced = "evtchn,gnttab";

It is OK to panic if the user specifies an option that is currently
unsupported (e.g. "gnttab").

In practice xenstore requires both gnttab and evtchn, I don't know if we
want to write that down in the device tree bindings. We could panic if
the user specifies: xen,enhanced = "xenstore,evtchn";

What do you guys think?

Correct.

Yes with some cavears (see below).

So today, if you create the node "xen,xen", the guest will expect to be 
able to use both grant-table and event channel.

Therefore, in the list above, the only configuration we can sensibly 
support without any major rework is "evtchn,gnttab".

If we want to support "evtchn" or "gnttab" only. Then we likely need to 
define a new binding (or new version) because neither "regs" nor 
"interrupts" are optional (although a guest OS is free to ignore them).

I think the interface for dom0less domUs is quite messy at the moment. 
Even if we don't advertise the support for event channel and 
grant-table, hypercalls. They are still accessible if the guest wish to 
do so.

If we decide to introduce "evtchn", "gnttab" & co then we should also 
make sure that if "evtchn" is not specified then we are not allowing the 
guest to allocate any event channel (or map the grant-table).

Otherwise, this is pointless if we try to tell the user "evtchn", 
"gnttab"...

And just to be clear, I would be perfectly happy to break anyone trying
to use event channel without "xen,enanced" because we didn't advertise 
the feature. So they should not use it.

Cheers,

Yes I think you are right. I also broadly agree with the rest of your
reply.

Thinking about it and given the above, we only need 2 "levels" of
enhancement:

1) everything: xenstore, gnttab, evtchn
2) gnttab, evtchn, but not xenstore

Nothing else is really possible because, as Julien pointed out,
"xen,enhanced" implies the xen,xen node in the domU device tree and in
turn that node implies both evtchn and gnttab.

xenstore is separate and is detected using HVM_PARAM_STORE_EVTCHN and
HVM_PARAM_STORE_PFN anyway.

So I think we just need to add a way to express 2). We could do
something like:

  xen,enhanced = "evtchn,gnttab";

Or we could use a new separate option like Julien initially suggested,
e.g.:

  xen,enhanced-no-xenstore;

"xen,enhanced-no-xenstore" is a terrible name actually, but just to
explain what I am thinking :-)

I haven't been able to find evidence of "-nopie" ever having been a
supported compiler option. The correct spelling is "-no-pie".
Furthermore like "-pie" this is an option which is solely passed to the
linker. The compiler only recognizes "-fpie" / "-fPIE" / "-fno-pie", and
it doesn't infer these options from "-pie" / "-no-pie".

Add the compiler recognized form, but for the possible case of the
variable also being used somewhere for linking keep the linker option as
well (with corrected spelling).

This is supposed to be coming from EMBEDDED_EXTRA_CFLAGS, if only
it was spelled correctly there. See the patch just sent. This line
(see that other patch) is meaningless anyway, as we don't use
$(CFLAGS) for linking here. So with it dropped

I do think though that the description could do with some expanding,
as I don't think -fpic or -fPIC is the default normally. I suppose
it's only specific distros which make this the default.

Even after removing 'type=3Dnetfront' from vif it's failing.
One more doubt here, could this mac address be a dummy or actual here?

You don&#39;t actually need to mount<br>
xen-guest-image-minimal-raspberrypi4-64.ext3 anywhere to use it to run<br>
your guest VM with &quot;xl create&quot;. <br>
<br>
It is enough to do this instead, as Bertrand suggested:<br>
<br>
disk=3D[&quot;file:/path/to/file/xen-guest-image-minimal-raspberrypi4-64.ex=
t3,xvda,w&quot;]<br>
<br>
No need to call losetup or mount. Just xl create -c.<br>

You will want to actually Cc him on v2, so he can ack the change (or
not).

Before proceeding discussion, I would like step back to get clear for
the GIC implementation in Xen, otherwise, it's really hard for me to
catch up the dicussion :)

For me it's clear that Xen emulates GICv3 for DomU, but I am still
confused how GICv3 works for Dom0.

Xen directly passes ACPI MADT table from UEFI to Linux kernel to Dom0,
(see functions acpi_create_madt() and gic_make_hwdom_madt()), which
means the Linux kernel Dom0 uses the same ACPI table to initialize GICv3
driver, but since Linux kernel Dom0 accesses GIC memory region as IPA,
it still trap to Xen in EL2 for stage 2 translation, so finally Xen
can emulate the GICv3 device for Dom0.

This is quite different from DomU.  Xen prepares a DT node for GICv3
rather than directly passing ACPI table, so DomU kernel initializes
GICv3 driver based on the DT binding.

Simply to say, no matter Dom0 using ACPI table or DomU using DT
binding, at the end Xen emulates GICv3 device for all of them.

Another thing is not clear for me is that I can see Xen allocates
redistributor pending page (see gicv3_lpi_set_pendtable()), after Dom0
or DomU kernel boots up, kernel allocates another RD pending page; so
the question is how these two different pending pages co-work
together.

In other words, let's assume the Dom0 kernel panic and its secondary
kernel is launched by kexec, is it necessarily for the secondary
kernel to reuse the primary kernel's RD pending page?  Or in this case
it's no matter for the RD pending page in Dom0 and it's safe for Xen
always maintains its own RD pending page in EL2?

Let me ask a stupid question.  Seems to me, GICR LPI tables can be
configured as below options

- The hypervisor pre-allocates GICR LPI tables and pass the memory
  region info to Dom0 kernel;

- The hypervisor doesn't allocate GICR LPI tables, and then Dom0
  kernel allocates GICR LPI tables for the virtual GICv3, and Dom0
  directly write data to the GICR LPI tables and the table is used by
  physical GICv3;

- The hypervisor pre-allocates GICR LPI tables for phycial GICv3 and
  Dom0 kernel allocates another GICR LPI tables for virtual GICv3,
  and Xen needs to sync between these two tables.

To be clear, all of above three options are hypothesis.  So please
correct me if anything is wrong (or even total are wrong?!).

Thanks a lot for suggestions!

Leo

P.s. sorry for truncating Marc's following comments, just want to
focus on above questions.

And intentionally so - the caller didn't ask for any bigger region,
after all.

I'm afraid we're trusting the firmware in this regard elsewhere as
well. So if there was a need to change that, I guess it would need
changing everywhere, not just here. But we trust the E820 map as
well, when on non-EFI platforms, so I don't see why we would need
to change that. In any event such would want to be a separate
change imo.

If you were to report a larger ending address, why would you not also
report a smaller starting address?

But before you go that route - I don't think we can change the API
now that it has been in use this way for many years. If a "give me
the full enclosing range" variant is wanted, it will need to be
fully separate.

So, IIUC, the only deviations from the MISRA C 2012 Rule 20.7 will be 
for macro parameters used as the lhs of assignments and function arguments?

This feels a bit of a hack to parenthesize the macro parameters that are 
used as the rhs of an assignment but not those used as the lhs.
 From previous discussions on the topic, I understood that the 
parentheses are considered needed only when they eliminate operator 
precedence problems, while for the wrong parameter format bugs we can 
rely on the reviewers.

I think we need to decide if the rule will be applied as is and if not 
which will be the deviations along with their justification and add it 
to the document.

The addition of the "memory" clobber imo wants mentioning in the
description, so it's clear that it's intentional (and why).

I'm inclined to ask to use "outb %1, %0" here (and similarly below).
I also wonder whether at least all the OUTs shouldn't also gain a
"memory" clobber.

Would you mind adding blanks after the comma here and below?

Seeing this #define here, does there anything stand in the way of
putting IOAPIC_BASE_ADDRESS next to the inline functions as well?

Afaic I don't consider that discussion settled.

lhs and rhs of assignments are quite different, and hence making such a
distinction wouldn't look to be a "hack" to me. In fact I've always
considered this part of the language somewhat strange: To me
parenthesizing e.g. an identifier already makes it (visually) an
rvalue. Leaving aside odd (and easy to spot as odd) uses at the call
sizes, I don't think I can come up with a case where parentheses are
really needed. Anything needing parenthesizing actually yields an
rvalue afaics, thus causing a diagnostic anyway.

Yes. But this shouldn't hinder adjustments for all other, non-
controversial cases.

It's been a long time since I last needed to access that, when it
was still /proc/mem and/or /proc/kmem. Their modern equivalents might
be /sys/devices/virtual/mem/{,k}mem ... But if that's not usable to
get at the needed data, perhaps we should go with logging it by way
of a patch to Xen. Please let me know if I need to hand you a patch
to do so.

In ACPI or in EFI? In the latter case suppressing the use of the EFI
runtime service for shutdown/reboot may help ("efi=no-rs" to disable
all runtime services use might be a good first try).

Don't know.

Hi Bertrand,

Thanks!

No, I couldn't see /dev/loop0. Can you please guide me to create it?

I didn't change dom0 configurations, it's default generated by yocto.

I will append this "IMAGE_FSTYPES:append =3D " wic.gz=E2=80=9D" in local.co=
nf & will
update you.

Regards,
Vipul Kumar

<br>
I think you have a loop issue.<br>
<br>
Could you check if /dev/loop0 exists ?<br>
<br>
Did you change something on the dom0 linux configuration generated by Yocto=
 ?<br>
<br>
We are using Yocto on RPI4 here without any issue like that, only differenc=
e with<br>
your setup is that we generate a wic image to have a real disk image instea=
d of<br>
using the ext3/ext4 one.<br>
<br>
Should be possible to do the same on your side by adding the following in l=
ocal.conf:<br>
IMAGE_FSTYPES:append =3D &quot; wic.gz=E2=80=9D<br>
<br>
&gt; <br>
&gt; Even after removing &#39;type=3Dnetfront&#39; from vif it&#39;s failin=
g. <br>
<br>
This option is only for hvm on x86, so you can remove it from your configur=
ation.<br>
<br>
&gt; One more doubt here, could this mac address be a dummy or actual here?=
<br>
<br>
This is a dummy one you set for the guest network interface and this is the=
 Mac<br>
=C2=A0address other devices on your network will see so it must be fully va=
lid (and<br>
=C2=A0not conflicting with other devices on your network).<br>

&gt; &gt; I am trying to mount xen-guest-image-minimal-raspberrypi4-64.ext3=
 to a virtual device &amp; then will run the guest VM by command &quot;xl c=

&gt; &gt; guest.cfg&quot;. But facing issue while trying to mount. <br>
&gt; <br>
&gt; You don&#39;t actually need to mount<br>
&gt; xen-guest-image-minimal-raspberrypi4-64.ext3 anywhere to use it to run=
<br>
&gt; your guest VM with &quot;xl create&quot;. <br>
&gt; <br>
&gt; It is enough to do this instead, as Bertrand suggested:<br>
&gt; <br>
&gt; disk=3D[&quot;file:/path/to/file/xen-guest-image-minimal-raspberrypi4-=
64.ext3,xvda,w&quot;]<br>
&gt; <br>
&gt; No need to call losetup or mount. Just xl create -c.<br>

In the default setup, dom0 is also the hardware domain. So it owns all 
of the devices but the ones used by Xen (e.g. interrupt controller, SMMU).

Therefore, dom0 will use the same memory layout as the host. At which 
point, it is a lot more convenient to re-use the host ACPI tables and 
rewrite only what's necessary.

DomUs memory layout is defined by Xen. So we need to create the 
Device-Tree and ACPI tables (both are supported) from scrartch.

Correct. In both situations the GICv3 will be owned by Xen and we will 
emulate the bits that are not virtualized by the CPUs (e.g. 
re-distributors).

Xen allocates the pending pages that will be used by the host. Dom0/DomU 
will be allocating pending pages that will be used by the virtual GICv3.

No.

Dom0 doesn't have direct access to the host GICv3 (this will be 
controlled by Xen). What we expose to dom0 is a virtual GICv3.

So effectively we have two different GICv3 and each of them will require 
their own set of pending table.

I will defer this question to Marc.

Subject: [PATCH v2] xen/privcmd: fix error exit of privcmd_ioctl_dm_op()

Content-Transfer-Encoding: 8bit

The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.

Additionally lock_pages() doesn't check for pin_user_pages_fast()
having been completely successful, resulting in potentially not
locking all pages into memory. This could result in sporadic failures
when using the related memory in user mode.

Fix all of that by calling unlock_pages() always with the real number
of pinned pages, which will be zero in case pages being NULL, and by
checking the number of patches pinned by pin_user_pages_fast()
matching the expected number of pages.

Not really, Xenstore has always been part of the story in Xen. So I 
think making it optional for "xen,enhanced" is going to make more 
difficult for user to understand what the meaning of the option (in 
particular that in the future we may want to support Xenstored in a 
separate domain).

I would be fine with it.

I don't like the idea of introducing yet another option.

See above about disabling Xenstore automatically.

Do you mean when "xen,enhanced" is specified? If yes, this could be 
useful if one want to limit the interface exposed to the guest.

I agree we still have the flexibility to change.

Subject: [PATCH v2] x86/public: move XEN_ACPI_ in a new header
Date: Thu, 25 Aug 2022 10:48:43 +0100
Message-Id: <c869f79901968de2d71ab56e1bbb5d43048baf5d.1661420219.git.bertrand.marquis@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

When Xen is compiled for x86 on an arm machine, libacpi build is failing
due to a wrong include path:
- arch-x86/xen.h includes xen.h
- xen.h includes arch-arm.h (as __i386__ and __x86_64__ are not defined
but arm ones are).

To solve this issue move XEN_ACPI_ definitions in a new header
guest-acpi.h that can be included cleanly by mk_dsdt.c.
Inside this header, only protect the definitions using ifdef
__XEN_TOOLS__ as the defines are not used anywhere in the hypervisor and
are not expected to be.

Previous users needing any of the XEN_ACPI_ definitions will now need to
include arch-x86/guest-acpi.h instead of arch-x86/xen.h

Fixes: d6ac8e22c7c5 ("acpi/x86: define ACPI IO registers for PVH guests")
Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
---
The x86 header is including ../xen.h before the ifndef/define so that it
gets included back by xen.h. This is wrongly making the assumption that
we are using an x86 compiler which is not the case when building the
tools for x86 on an arm host.
Moving the definitions to an independent header is making things cleaner
but some might need to include a new header but the risk is low.

For the release manager:
- risk: very low, the definitions moved are only used in mk_dsdt and
external users would just have to include the new header.
- advantage: we can now compile xen for x86 on arm build machines
---
Changes in v2:
- fix commit message
- remove ifdef __XEN__ protecting the definitions
- fix name in description and ifdef guards of the file
- fix description
Changes in v1:
- was "libacpi: Fix cross building x86 on arm"
- move XEN_ACPI_ definitions in a new header guest-acpi.h
- adapt mk_dsdt.c
- remove todo in public header

Nit: s/patches/pages/

I have a question / suggestion, though:

I don't really know the inner workings of pin_user_pages_fast()
nor what future plans there are with it. To be as independent of
its behavior as possible, how about bailing here only when
page_count actually is zero (i.e. no forward progress)?

Oh, I see - I've misread the code as if the loop was capping each
iteration's count to the capacity of some internal buffer (as iirc
is being done elsewhere). So ...

... unless you think this might be relevant in certain cases.

Doing some git archeology:

So the commit which added mtrr_aps_delayed_init is

  d0af9eed5aa9 ("x86, pat/mtrr: Rendezvous all the cpus for MTRR/PAT init")

from 2009.

The IPI callback before it, looked like this:

static void ipi_handler(void *info)
{
#ifdef CONFIG_SMP
	struct set_mtrr_data *data = info;
	unsigned long flags;

	local_irq_save(flags);

	atomic_dec(&data->count);
	while (!atomic_read(&data->gate))
		cpu_relax();

	/*  The master has cleared me to execute  */
	if (data->smp_reg != ~0U) {
		mtrr_if->set(data->smp_reg, data->smp_base,
			     data->smp_size, data->smp_type);
	} else {
		mtrr_if->set_all();
		^^^^^^^^^

and that else branch would call ->set_all() on Cyrix too.

Suresh's patch changed it to do:

-	} else {
+	} else if (mtrr_aps_delayed_init) {
+		/*
+		 * Initialize the MTRRs inaddition to the synchronisation.
+		 */
 		mtrr_if->set_all();

BUT below in the set_mtrr() call, it did:

        /*
         * HACK!
         * We use this same function to initialize the mtrrs on boot.
         * The state of the boot cpu's mtrrs has been saved, and we want
         * to replicate across all the APs.
         * If we're doing that @reg is set to something special...
         */
        if (reg != ~0U)
                mtrr_if->set(reg, base, size, type);
        else if (!mtrr_aps_delayed_init)
                mtrr_if->set_all();
		^^^

and that would be the Cyrix case.

But then

  192d8857427d ("x86, mtrr: use stop_machine APIs for doing MTRR rendezvous")

came and "cleaned" all up by removing the "HACK" and doing ->set_all()
only in the rendezvous handler:

+       } else if (mtrr_aps_delayed_init || !cpu_online(smp_processor_id())) {
                mtrr_if->set_all();
        }

Which begs the question: why doesn't the second part of the else test
match on Cyrix? The "|| !cpu_online(smp_processor_id())" case.

If only we had a Cyrix machine somewhere...

I don't think this can be __ro_after_init, or you'll break CPU
hotplug.

Same here.

This, otoh, can be, or have I missed a place where it's written by a
non-__init function?

I don't think you can use nodeid_t for a variable holding a node count.
Think of what would happen if there were 256 nodes, the IDs of which
all fit in nodeid_t. (Same again further down.)

This is likely inefficient for a loop counter variable. Note how you
use "unsigned int" in e.g. extract_lsb_from_nodes().

With this the function can't very well have "unsigned int" return type.

"unsigned int" for i and perhaps nodeid_t for rr?

uint64_t and a blank line between declaration(s) and statement(s)

Does the compiler not warn here, comparing an unsigned value for being
negative?

Please could you take the opportunity and drop unnecessary parentheses
from here? Afaict only parent_node() need them to be kept.

Please can you have variable and function declarations visually separated,

Nit: The conventional place for attributes is between return type
and function (or object) name.

Again please take the opportunity and drop the unnecessary inner
parentheses.

Pleae correct indentation here - it was correct originally (except
for the fact that it was using hard tabs).

Did you consider putting reserved_heap into bootinfo structure?
It would help to avoid introducing new global variables that are only used
in places making use of the bootinfo anyway.

You do not need reserved_heap_start as you do not use it at any place later on.
In your current implementation you just need reserved_heap_size and reserved_heap_end.

I must say that the reverted logic is harder to read. This is a matter of taste but
please consider the following:
heap_pages = reserved_heap ? reserved_heap_pages : ram_pages;
The same applies to ...

I'm not sure about this. You are checking if the size of the reserved heap is less than 32MB
and this has nothing to do with the following panic message.

Hi Julien,

If the answer is no, then I think it's feasible to pass the same ACPI
table or DT binding for virtual GICv3 from primary kernel to secondary
kernel, then the second kernel can initialize the VGIC and allocate a
new RD tables (and trap to Xen in EL2 to handle the new allocated RD
tables).  How about you think for this?

Thanks a lot for quick response.

Subject: [PATCH v3] xen/privcmd: fix error exit of privcmd_ioctl_dm_op()
Date: Thu, 25 Aug 2022 13:40:04 +0200
Message-Id: <20220825114004.24843-1-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.

Additionally lock_pages() doesn't check for pin_user_pages_fast()
having been completely successful, resulting in potentially not
locking all pages into memory. This could result in sporadic failures
when using the related memory in user mode.

Fix all of that by calling unlock_pages() always with the real number
of pinned pages, which will be zero in case pages being NULL, and by
checking the number of pages pinned by pin_user_pages_fast() matching
the expected number of pages.

V2:
- use "pinned" as parameter for unlock_pages() (Jan Beulich)
- drop label "unlock" again (Jan Beulich)
- add check for complete success of pin_user_pages_fast()
V3:
- continue after partial success of pin_user_pages_fast() (Jan Beulich)

Right.

I know you're eager to remove dead code - I'd love that too. But before
we do that, we need to find out whether some Cyrix hw out there would
not need this.

I know, I know, they should've complained by now ... maybe they have but
we haven't heard about it.

What it most likely looks like is that those machines - a commit from
before git

commit 8fbdcb188e31ac901e216b466b97e90e8b057daa
Author: Dave Jones <davej@suse.de>
Date:   Wed Aug 14 21:14:22 2002 -0700

    [PATCH] Modular x86 MTRR driver.

talks about

+/*
+ * On Cyrix 6x86(MX) and M II the ARR3 is special: it has connection
+ * with the SMM (System Management Mode) mode. So we need the following:
+ * Check whether SMI_LOCK (CCR3 bit 0) is set
+ *   if it is set, write a warning message: ARR3 cannot be changed!
+ *     (it cannot be changed until the next processor reset)

which sounds like old rust. And which no one uses or such machines are
long dead already.

Wikipedia says:

https://en.wikipedia.org/wiki/Cyrix_6x86

"The Cyrix 6x86 is a line of sixth-generation, 32-bit x86
microprocessors designed and released by Cyrix in 1995..."

So I'm thinking removing it would be ok...

We cannot purely talk about interrupt handling without connecting with
device driver model.

Seems to me, to support para virtualization driver model (like virtio),
Dom0 needs to provide the device driver backend, and DomUs enables
the forend device drivers.  In this case, the most hardware interrupts
(SPIs) are routed to Dom0.

To support passthrough driver model (VFIO), Xen needs to configure the
hardware GICv3 to directly route hardware interrupt to the virtual CPU
interface.

But here I still cannot create the concept that how GIC RD tables play
roles to support the para virtualization or passthrough mode.

Thanks,

Initially I thought this would go wrong only on the 3rd iteration, but
meanwhile I think it's wrong already on the 2nd. What I think you need
is

		if (page_count < requested)
			i--;
		off += page_count;

or with the i++ from the loop header absorbed here

		if (page_count == requested)
			i++;
		off += page_count;

Plus of course off needs resetting to zero whenever i advances. I.e.

		if (page_count == requested) {
			i++;
			off = 0;
		} else {
			off += page_count;
		}

Since the comment is intended to apply to all architectures providing,
I think it should go with the declaration (once) rather than the
definition (at least one instance per arch).

EINVAL is so heavily (over)loaded that I'm inclined to ask to use e.g.
-ENODATA here.

What if an arch returns a 3rd error indicator? The way you've written
it code below would assume success and use uninitialized data. I'd
like to suggest to only special-case -ENOENT and treat all other
errors the same. But of course the variable (re)used doesn't really
fit that:

		/* Reach the end of arch's memory map */
		if (found == -ENOENT)
			break;

		/* Index relate entry is not RAM, skip it. */
		if (found)
			continue;

because here really you mean "not found". Since in fact "found" would
want to be of "bool" type in the function, and "j" would want to be
"unsigned int" just like "i" is, I recommend introducing a new local
variable, e.g. "err".

May I ask that you re-flow this to either

static enum conflicts __init
conflicting_memblks(nodeid_t nid, paddr_t start,

or

static enum conflicts __init conflicting_memblks(
    nodeid_t nid, paddr_t start,

?

This is kind of clumsy, but I have no better suggestion.

The function only ever returns 0 or -EINVAL - please consider switching
to "bool" return type.

Hmm, if I'm not mistaken one of the two printk()s and hence also one of
the two format strings will be dead code / data on every archiecture.
I wonder if we don't want to have a HAS_NUMA_FW_NODE_ID (name subject
to improvment) Kconfig setting to avoid such. I could imagine this to
become relevant also in other code.

This function returns only 0 or -1, i.e. is even more of a candidate
for having "bool" return type than numa_update_node_memblks().

May I suggest to eliminate "size" at this occasion, for being used
only once and rather not helping readability (imo at least)?

I'm sorry, but I guess this may go about anywhere in the file, but not
right at the top. I would probably have put it ahead of npfec_kind_t
or right after dom_cow.

I think that would work.

That's correct. Most of the shared interrupts will be routed to dom0.

Do you mean GICv4 rather than GICv3? In the latter, all the interrupts 
will be received in Xen and then routed to the domain by updating the LRs.

I am not sure what you are actually asking. The pending tables are just 
memory you give to the GICv3 to record the state of the interrupts.

Especially the uses of "NUMA nodes number" make this read somewhat
odd. If I was to re-write all of this, it would become something
like:

Currently the maximum number of NUMA nodes is a hardcoded value.
This provides little flexibility unless changing the code.

Introduce a new Kconfig option to change the maximum number of
NUMA nodes conveniently. Also considering that not all
architectures support NUMA, this Kconfig option is only visible
on NUMA enabled architectures. Architectures not supporting NUMA
still use 1 for MAX_NUMNODES.

Acked-by: Jan Beulich <jbeulich@suse.com>

Note that there's an alternative with less #ifdef-ary:

config NR_NUMA_NODES
	int "Maximum number of NUMA nodes supported" if NUMA
	range 2 64 if NUMA
	default "1" if !NUMA
	default "64"

But I can see reasons why one might deem it better for there to
not be any CONFIG_NR_NUMA_NODES in the resulting .config when
!NUMA.

Subject: [PATCH v4] xen/privcmd: fix error exit of privcmd_ioctl_dm_op()
Date: Thu, 25 Aug 2022 16:19:18 +0200
Message-Id: <20220825141918.3581-1-jgross@suse.com>
X-Mailer: git-send-email 2.35.3
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.

Additionally lock_pages() doesn't check for pin_user_pages_fast()
having been completely successful, resulting in potentially not
locking all pages into memory. This could result in sporadic failures
when using the related memory in user mode.

Fix all of that by calling unlock_pages() always with the real number
of pinned pages, which will be zero in case pages being NULL, and by
checking the number of pages pinned by pin_user_pages_fast() matching
the expected number of pages.

V2:
- use "pinned" as parameter for unlock_pages() (Jan Beulich)
- drop label "unlock" again (Jan Beulich)
- add check for complete success of pin_user_pages_fast()
V3:
- continue after partial success of pin_user_pages_fast() (Jan Beulich)
V4:
- fix case of multiple partial successes for one buffer (Jan Beulich)

Thanks for clarification.

So GICv3 relies on hypervisor to set LR, and VM can use virtural
interface to response (ACK/EOI) the interrupt.  GICv4 can directly
forward the SPI to the CPU virtual interface (without hypervisor's
interfering).

For more specific, Xen has its own RD pending table, and we can use
this pending table to set state for SGI/PPI/LPI for a specific CPU
interface.  Xen works as hypervisor, it saves and restores the pending
table according to switched in VM context, right?

On the other hand, what's the purpose for Linux kernel's GIC RD
pending table?  Is it only used for nested virtulisation?  I mean if
Linux kernel's GIC RD pending table is not used for the drivers in
Dom0 or DomU, then it's useless to pass it from the primary kernel to
secondary kernel; as result, we don't need to reserve the persistent
memory for the pending table in this case.

Thanks,
Leo

Subject: [PATCH 1/2] xen-blkback: Advertise feature-persistent as user requested
Date: Thu, 25 Aug 2022 16:15:10 +0000
Message-Id: <20220825161511.94922-2-sj@kernel.org>

Commit e94c6101e151 ("xen-blkback: Apply 'feature_persistent' parameter
when connect") made blkback to advertise its support of the persistent
grants feature only if the user sets the 'feature_persistent' parameter
of the driver and the frontend advertised its support of the feature.
However, following commit 402c43ea6b34 ("xen-blkfront: Apply
'feature_persistent' parameter when connect") made the blkfront to work
in the same way.  That is, blkfront also advertises its support of the
persistent grants feature only if the user sets the 'feature_persistent'
parameter of the driver and the backend advertised its support of the
feature.

Hence blkback and blkfront will never advertise their support of the
feature but wait until the other advertises the support, even though
users set the 'feature_persistent' parameters of the drivers.  As a
result, the persistent grants feature is disabled always regardless of
the 'feature_persistent' values[1].

The problem comes from the misuse of the semantic of the advertisement
of the feature.  The advertisement of the feature should means only
availability of the feature not the decision for using the feature.
However, current behavior is working in the wrong way.

This commit fixes the issue by making the blkback advertises its support
of the feature as user requested via 'feature_persistent' parameter
regardless of the otherend's support of the feature.

Subject: [PATCH 2/2] xen-blkfront: Advertise feature-persistent as user requested

Commit e94c6101e151 ("xen-blkback: Apply 'feature_persistent' parameter
when connect") made blkback to advertise its support of the persistent
grants feature only if the user sets the 'feature_persistent' parameter
of the driver and the frontend advertised its support of the feature.
However, following commit 402c43ea6b34 ("xen-blkfront: Apply
'feature_persistent' parameter when connect") made the blkfront to work
in the same way.  That is, blkfront also advertises its support of the
persistent grants feature only if the user sets the 'feature_persistent'
parameter of the driver and the backend advertised its support of the
feature.

Hence blkback and blkfront will never advertise their support of the
feature but wait until the other advertises the support, even though
users set the 'feature_persistent' parameters of the drivers.  As a
result, the persistent grants feature is disabled always regardless of
the 'feature_persistent' values[1].

The problem comes from the misuse of the semantic of the advertisement
of the feature.  The advertisement of the feature should means only
availability of the feature not the decision for using the feature.
However, current behavior is working in the wrong way.

This commit fixes the issue by making the blkfront advertises its
support of the feature as user requested via 'feature_persistent'
parameter regardless of the otherend's support of the feature.

We have agreement on this, so I would say let's keep it simple and go
with this option.

I am OK with what you wrote as well, but considering the additional
complexity that no-gnttab and no-evtchn entail given that they cannot be
actually disabled today, I suggest to keep it simple and go with:

xen,enhanced = "no-xenstore"

CC MISRA C working group

Short summary: we are discussing whether the following is sufficient to
address MISRA C Rule 20.7, and also in general for safety:


 #define dt_for_each_property_node(dn, pp)                   \
-    for ( pp = dn->properties; pp != NULL; pp = pp->next )
+    for ( pp = (dn)->properties; pp != NULL; pp = (pp)->next )


as you can see "dn" has been parenthesizing because is used as a rhs,
while "pp" has *not* because it is used as lhs.

More below.

Although I can see where you are coming from, parenthesizing an
identifier doesn't actually make it an rvalue. Also it is a lot simpler
to understand, review, and apply a policy that says:

"all macro parameters are parenthesized"

compared to a policy that says:

"most macro paremeters are parenthesized, let's go into the details of
which ones are parenthesized and which ones are not, including examples
and corner cases"

For simplicity, I would go with the simplest version, the MISRA version.

I am assuming that the MISRA Rule 20.7 requires that "pp" is also
parenthesized. Roberto, is that correct?

It looks like we need a discussion and see where the majority of the
team is on this issue. I prefer the original MISRA version for
simplicity, but I also think it is OK if we make a small customization
to it. In that case, we would add the extra explanation and details to
docs/misra/rules.rst.

However, as we make the decision we also need to take into account that
if we don't go with the vanilla MISRA rule, there is a price to pay: all
the MISRA scanners, including cppcheck, Eclair, Coverity and others would
probably still flag these issues as violations polluting the results
and making the scanners less useful. We might have to mark each
"deviation" with a one-line in-code comment on top, or we would have to
disable automatic scanning for Rule 20.7 altogether. Either option is
not great.

This is actually the main reason why I prefer the vanillay MISRA
version: even if the resulting style might not be as good the the custom
version, we don't need to worry about reviewing this rule because we can
easily get automatic scans for it.


But first, let's confirm whether this change:


 #define dt_for_each_property_node(dn, pp)                   \
-    for ( pp = dn->properties; pp != NULL; pp = pp->next )
+    for ( pp = (dn)->properties; pp != NULL; pp = (pp)->next )


is sufficient to make the violation go away in Eclair or cppcheck.  I am
assuming it is not sufficient, but let's confirm.

Well, even if for the lhs of assignments there was an exception, this
still wouldn't be sufficient. The minimum needed is

#define dt_for_each_property_node(dn, pp)                   \
    for ( pp = (dn)->properties; (pp) != NULL; pp = (pp)->next )

The XenoLinux forward port of ours did, and upstream Linux still wrongly
doesn't. The two functions efi_mem_type() and efi_mem_attributes() still
wrongly fail there when running on Xen.

But how does this matter? Even if we were unaware of any users of the API,
we can't know there are none.

As an aside: Something's odd with your reply. When I opened the window to
write this reply, Marek and the list were put into To: (instead of Cc:)
and you were dropped altogether. I can only guess that this is what
Thunderbird made of the Mail-Followup-To: tag which your mail has.

As indicated in reply to your patch changing XEN_FW_EFI_MEM_INFO in
the hypervisor: While this may fit the ESRT purpose, the address you
return here is not necessarily the start of the region, and hence
this function is not a general Xen replacement for the non-Xen
function. Therefore I think it also shouldn't give the impression of
doing so.

If pp is assumed to be a valid lvalue, then why it is needed to add 
parentheses here (pp) != NULL ?

For the violations to go away, parentheses should be placed around all 
macro parameters that represent expressions, that is
#define dt_for_each_property_node(dn, pp)                   \
       for ( (pp) = (dn)->properties; (pp) != NULL; (pp) = (pp)->next )

Subject: [PATCH 02/12] xen/arm: add cache coloring initialization for domains
Date: Fri, 26 Aug 2022 14:51:01 +0200
Message-Id: <20220826125111.152261-3-carlo.nonato@minervasys.tech>
X-Mailer: git-send-email 2.34.1

This commit adds array pointers to domains as well as to the hypercall
and configuration structure employed in domain creation. The latter is used
both by the toolstack and by Xen itself to pass configuration data to the
domain creation function, so the XEN_GUEST_HANDLE macro must be adopted to be
able to access guest memory in the first case. This implies special care for
the copy of the configuration data into the domain data, meaning that a
discrimination variable for the two possible code paths (coming from Xen or
from the toolstack) is needed.

The initialization and free functions for colored domains are also added.
The former is responsible for allocating and populating the color array
of the domain and it also checks for configuration issues. One of those
issues is enabling both coloring and directmap for the domain because they
contradicts one another. Since that, Dom0 must not be created with the
directmap flag.
The latter instead frees allocated memory.

Add a new "colors" parameter that defines the color assignment for a
domain. The user can specify one or more color ranges using the same
syntax used everywhere else for color config described in the documentation.
The parameter is defined as a list of strings that represent the
color ranges.
Also documentation is added.

This commit adds the cache coloring support initialization, Kconfig options,
command line parameters and the initial documentation.
The initialization consists of an auto probing of the cache layout
necessary to retrieve the LLC way size which is used to compute the
number of available colors. The Dom0 colors are then initialized with default
colors (all available ones) if not provided from the command line, and
they are checked for bad configuration.

It also adds a debug-key to dump general cache coloring info.
This includes LLC way size, total available colors and the mask used to
extract colors from physical addresses.

+Xen cache coloring user guide
+=============================
+
+The cache coloring support in Xen allows to reserve Last Level Cache (LLC)
+partition for Dom0, DomUs and Xen itself. Currently only ARM64 is supported.
+
+In order to enable and use it, few steps are needed.
+
+- Enable cache coloring in Xen configuration file.
+
+        CONFIG_CACHE_COLORING=y
+- If needed, change the maximum number of colors in Xen configuration file
+  (refer to menuconfig help for value meaning and when it should be changed).
+
+        CONFIG_MAX_CACHE_COLORS=<n>
+- Assign colors to Dom0 using the `Color selection format`_ (see
+  `Coloring parameters`_ for more documentation pointers).
+
+Background
+**********
+
+Cache hierarchy of a modern multi-core CPU typically has first levels dedicated
+to each core (hence using multiple cache units), while the last level is shared
+among all of them. Such configuration implies that memory operations on one
+core (e.g. running a DomU) are able to generate interference on another core
+(e.g .hosting another DomU). Cache coloring allows eliminating this
+mutual interference, and thus guaranteeing higher and more predictable
+performances for memory accesses.
+The key concept underlying cache coloring is a fragmentation of the memory
+space into a set of sub-spaces called colors that are mapped to disjoint cache
+partitions. Technically, the whole memory space is first divided into a number
+of subsequent regions. Then each region is in turn divided into a number of
+subsequent sub-colors. The generic i-th color is then obtained by all the
+i-th sub-colors in each region.

+          . . ..................................:
+    </pre>
+
+There are two pragmatic lesson to be learnt.
+
+1. If one wants to avoid cache interference between two domains, different
+   colors needs to be used for their memory.
+
+2. Color assignment must privilege contiguity in the partitioning. E.g.,
+   assigning colors (0,1) to domain I  and (2,3) to domain  J is better than
+   assigning colors (0,2) to I and (1,3) to J.
+
+How to compute the number of colors
+***********************************
+
+To compute the number of available colors for a specific platform, the size of
+a LLC way and the page size used by Xen must be known. The first parameter can
+be found in the processor manual or can be also computed dividing the total
+cache size by the number of its ways. The second parameter is the minimum amount
+of memory that can be mapped by the hypervisor, thus dividing the way size by
+the page size, the number of total cache partitions is found. So for example,
+an Arm Cortex-A53 with a 16-ways associative 1 MiB LLC, can isolate up to 16
+colors when pages are 4 KiB in size.
+
+Cache layout is probed automatically by Xen itself, but a possibility to
+manually set the way size it's left to the user to overcome failing situations
+or for debugging/testing purposes. See `Coloring parameters`_ section for more
+information on that.
+
+Colors selection format
+***********************
+
+Regardless of the memory pool that has to be colored (Xen, Dom0/DomUs),
+the color selection can be expressed using the same syntax. In particular a
+comma-separated list of colors or ranges of colors is used.
+Ranges are hyphen-separated intervals (such as `0-4`) and are inclusive on both
+sides.
+
+Note that:
+ - no spaces are allowed between values.
+ - no overlapping ranges or duplicated colors are allowed.
+ - values must be written in ascending order.
+
+Examples:
+
++---------------------+-----------------------------------+
+|**Configuration**    |**Actual selection**               |
++---------------------+-----------------------------------+
+|  1-2,5-8            | [1, 2, 5, 6, 7, 8]                |
++---------------------+-----------------------------------+
+|  4-8,10,11,12       | [4, 5, 6, 7, 8, 10, 11, 12]       |
++---------------------+-----------------------------------+
+|  0                  | [0]                               |
++---------------------+-----------------------------------+
+
+Coloring parameters
+*******************
+
+LLC way size (as previously discussed) and Dom0 colors can be set using the
+appropriate command line parameters. See the relevant documentation in
+"docs/misc/xen-command-line.pandoc".

Subject: [PATCH 00/12] Arm cache coloring
Date: Fri, 26 Aug 2022 14:50:59 +0200
Message-Id: <20220826125111.152261-1-carlo.nonato@minervasys.tech>

Shared caches in multi-core CPU architectures represent a problem for
predictability of memory access latency. This jeopardizes applicability
of many Arm platform in real-time critical and mixed-criticality
scenarios. We introduce support for cache partitioning with page
coloring, a transparent software technique that enables isolation
between domains and Xen, and thus avoids cache interference.

When creating a domain, a simple syntax (e.g. `0-3` or `4-11`) allows
the user to define assignments of cache partitions ids, called colors,
where assigning different colors guarantees no mutual eviction on cache
will ever happen. This instructs the Xen memory allocator to provide
the i-th color assignee only with pages that maps to color i, i.e. that
are indexed in the i-th cache partition.

The proposed implementation supports the dom0less feature.
The solution has been tested in several scenarios, including Xilinx Zynq
MPSoCs.

Overview of implementation and commits structure
------------------------------------------------

- [1-3] Coloring initialization, cache layout auto-probing and coloring
  data for domains are added.
- [4-5] xl and Device Tree support for coloring is addedd.
- [6-7] A new page allocator for domain memory that implement the cache
  coloring mechanism is introduced.
- [8-12] Coloring support is added for Xen .text region.

Changes in v2
-------------

Lot of things changed between the two versions, mainly I tried to follow
all the comments left by the maintainers after the previous version review.
Here is a brief list of the major points (even if, imho, it's easier to
repeat all the review process):

 - One of the easiest change to spot is the reduced number of patches in the
   series. A lot of problems of bad splitting of commits where present before
   (documentation only in last commits, functionalities firstly introduced
   and later used in other commits, etc).
 - Definition of LLC (Last Level Cache) as the place where coloring applies
   should be more consistent throughout all the series (documentation and
   cache layout auto-probing code).
 - Kconfig option to let configure the maximum number of cache colors.
 - Only one kind of syntax to specify color configurations.
 - Only arrays to store colors (no more need for bitmaps).
 - No more limitations on the max number of colors (previously, because of
   a static assert failure, it was limited to 64).
 - Kconfig option to let configure the buddy allocator reserved size.
 - Removed the duplicated version of setup_pagetables.
 - No more need to expose vm_alloc function as non-static.

Open points and possible problems
---------------------------------

- The way xl passes user space memory to Xen it's adapted from various 
  points of the xl code itself (e.g. xc_domain_node_setaffinity) and it
  works, but it really needs attention from expert maintainers since 
  I'm not completely sure this is the correct way of doing things.
- We still need to bring back the relocation feature (part of) in order
  to move Xen memory to a colored space where the hypervisor could be
  isolated from VMs interference (see the revert commit #10 and the
  get_xen_paddr function in #12).
- Revert commits #8 and #9 are needed because coloring has the command
  line parsing as a prerequisite for its initialization and
  setup_pagetables must be called after it in order to color the Xen
  mapping. The DTB mapping is then added to the boot page tables instead
  of the Xen ones. Probably the way this is done is a bit simplistic.
  Looking forward for comments on the subject.
- A temporary mapping of the old Xen code (old here means non-colored)
  is used to reach variables in the old physical space so that secondary
  CPUs can boot. There were some comments in the previous version on that
  because the mapping is available for all the CPUs while only CPU0 is
  the one supposed to access it. I'm not sure how to temporarily mapping
  things only for the master CPU.
- A lot of #ifdef for cache coloring are introduced because I prefer to
  define functions only if they are actually needed. Let me know if you
  prefer a different approach.
- Julien posted an RFC to address a problem with the switch_ttbr function.
  For the moment I haven't considered it since it's still a work in progress.

This commit adds the "colors" Device Tree attribute that can be used for
DomUs and Dom0less color configurations. The syntax is the same used
for every color config.

Subject: [PATCH 06/12] xen/common: add cache coloring allocator for domains

This commit adds a new memory page allocator that implements the cache
coloring mechanism. The allocation algorithm follows the given color
configuration of the domain and maximizes contiguity in the page selection.

Pages are stored in a color-indexed data structure of lists, sorted by their
machine addresses, that are collectively called the colored heap. A simple
initialization function computes the color of any available page and inserts
it in the corresponding list. When a domain requests a page, the allocator
takes one from the subset of lists whose colors equals the domain
configuration. It chooses the page with the highest machine address such that
contiguous pages are sequentially allocated, if this is made possible by a
color assignment which includes adjacent colors.

The allocator can handle only requests with order equals to 0 since the
single color granularity is represented in memory by one page.

The buddy allocator must coexist with the colored one because the Xen heap
isn't colored. For this reason a new Kconfig option and a command line
parameter are added to let the user set the amount of memory reserved for
the buddy allocator. Even when cache coloring is enabled, this memory isn't
managed by the colored allocator.

+Colored allocator and buddy allocator
+*************************************
+
+The colored allocator distributes pages based on color configurations of
+domains so that each domains only gets pages of its own colors.
+The colored allocator is meant as an alternative to the buddy allocator because
+its allocation policy is by definition incompatible with the generic one. Since
+the Xen heap systems is not colored yet, we need to support the coexistence of
+the two allocators and some memory must be left for the buddy one.
+The buddy allocator memory can be reserved from the Xen configuration file or
+with the help of a command-line option.
+
+Known issues and limitations
+****************************
+
+Colored allocator can only make use of order-0 pages
+####################################################
+
+The cache coloring technique relies on memory mappings and on the smallest
+amount of memory that can be mapped to achieve the maximum number of colors
+(cache partitions) possible. This amount is what is normally called a page and,
+in Xen terminology, the order-0 page is the smallest one. The fairly simple
+colored allocator currently implemented, makes use only of such pages.
+It must be said that a more complex one could, in theory, adopt higher order
+pages if the colors selection contained adjacent colors. Two subsequent colors,
+for example, can be represented by a order-1 page, four colors correspond to
+a order-2 pages, etc.
+
+Fail to boot colored DomUs with large memory size
+#################################################
+
+If the Linux kernel used for Dom0 does not contain the upstream commit
+3941552aec1e04d63999988a057ae09a1c56ebeb and uses the hypercall buffer device,
+colored DomUs with memory size larger then 127 MB cannot be created. This is
+caused by the default limit of this buffer of 64 pages. The solution is to
+manually apply the above patch, or to check if there is an updated version of
+the kernel in use for Dom0 that contains this change.

This reverts commit 48fb2a9deba11ee48dde21c5c1aa93b4d4e1043b.

The cache coloring support has the command line parsing as a prerequisite
because of the color configurations passed in this way. Also, the Xen boot
module will be placed at an address that depends on the coloring
initialization. This commit moves the Xen boot module after the coloring
initialization to allow the order of operations previously described to
take place.

Date: Fri, 26 Aug 2022 14:51:08 +0200

From: Luca Miccio <lucmiccio@gmail.com>

This reverts commit 3a5d341681af650825bbe3bee9be5d187da35080.

The cache coloring support will be configurable within the Xen command line,
but it will be initialized before the page-tables; this is necessary
for coloring the hypervisor itself beacuse we will create a specific
mapping for it that could be configured using some command line options.
In order to parse all the needed information from the device tree, we
need to revert the above commit and restore the previous order for
page-tables initialization.

This reverts commit 0c18fb76323bfb13615b6f13c98767face2d8097.

Cache coloring support for Xen needs to relocate Xen code and data in a new
colored physical space. The BOOT_RELOC_VIRT_START will be used as the virtual
base address for a temporary mapping to this new space.

Subject: [PATCH 11/12] xen/arm: add Xen cache colors command line parameter

This commit adds a new command line parameter to configure Xen cache colors.
These colors can be dumped with the cache coloring info debug-key.

By default, Xen uses the first color.
Benchmarking the VM interrupt response time provides an estimation of
LLC usage by Xen's most latency-critical runtime task. Results on Arm
Cortex-A53 on Xilinx Zynq UltraScale+ XCZU9EG show that one color, which
reserves 64 KiB of L2, is enough to attain best responsiveness.

More colors are instead very likely to be needed on processors whose L1
cache is physically-indexed and physically-tagged, such as Cortex-A57.
In such cases, coloring applies to L1 also, and there typically are two
distinct L1-colors. Therefore, reserving only one color for Xen would
senselessly partitions a cache memory that is already private, i.e.
underutilize it. The default amount of Xen colors is thus set to one.

Subject: [PATCH 12/12] xen/arm: add cache coloring support for Xen
Date: Fri, 26 Aug 2022 14:51:11 +0200

This commit adds the cache coloring support for Xen own physical space.

It extends the implementation of setup_pagetables to make use of Xen cache
coloring configuration. Page tables construction is essentially the same
except for the fact that the physical addresses, in case of cache coloring,
are taken from the translation of a new, temporary, virtual space that is
physically colored.

The temporary mapping is also used to relocate Xen to the new physical space
starting at the address taken from the old get_xen_paddr() function which
is brought back for the occasion.
The temporary mapping is finally converted to a mapping of the "old" (meaning
the original physical space) Xen code, so that the boot CPU can actually
address the variables and functions used by secondary CPUs.
This happens when the boot CPU needs to bring up other CPUs (psci.c and
smpboot.c) and when the TTBR value is passed to them
(init_secondary_pagetables).

Finally, since the alternative framework needs to remap the Xen text and
inittext sections, this operation must be done in a coloring-aware way.
The function __vmap_colored is introduced for that. It actually is really
similar to the original __vmap, with the exception that it doesn't take for
granted that the physical memory is contiguous.

This doesn't build for me:

arch/arm/domain_build.c: In function ‘make_shm_memory_node’:
arch/arm/domain_build.c:1380:9: error: ISO C90 forbids variable length 
array ‘reg’ [-Werror=vla]
          __be32 reg[addrcells + sizecells];
          ^~~~~~

I haven't yet review the patch. But I think we would want to dynamically 
allocate 'reg' like we do in other places unless it is possible to know 
the maximum size of the array.

Cheers,

Your implementation below is checking for overlap and also have some 
restriction. Can they be documented in the binding?

In v5, we discussed to have the host address optional. However, the 
binding has not been updated to reflect that. Note that I am not asking 
to implement, but instead request that the binding can be used for such 
setup.

In both cases, end/bank_end may end up to be lower than 
paddr/mem->bank[i].start. So I think we also want to check that they 
don't overflow.

You have already validate the string. So you could use strcmp() here. 
Otherwise, it seems...

... odd to print the value if you don't trust it :).

I would prefer if we provide a dummy helper for process_shm_node() when 
!CONFIG_STATIC_SHM. This would also have the advantage to let the user 
know that they are trying to use shared memory with a Xen that doesn't 
support it.

Is the #ifdef really needed?

If I calculated right, the structure will grow from 24 to 40 bytes. At 
the moment, this is protected with CONFIG_STATIC_SHM which is 
unsupported. However, I think we will need to do something as we can't 
continue to grow 'membank' like that.

I don't have a quick suggestion for 4.17 (the feature freeze is in a 
week). Long term, I think we will want to consider to move the shm ID in 
a separate array that could be referenced here.

The other solution would be to have the shared memory regions in a 
separate array. They would have their own structure which would either 
embedded "membank" or contain a pointer/index to the bank.

Cheers,

Sorry, I should have stopped the issue with the call before. 
page_get_owner() can only be called for pages that are marked inuse. 
This is because the field "domain" is part of an union.

So I think you want to use page_get_owner_and_reference() here. The 
reference will have to be dropped using put_page(). I think it should be 
fine to do within the same function because we are still at init and 
therefore the page owner shouldn't change. I would explain that in a 
comment.

Let's not duplicate the call to page_get_owner(). You can use the result 
from the caller above and drop the reference afterwards (see above).

Should not we adjust "d->max_pages" if acquire_domstatic_pages() fails?

It is not quite clear why DOMID_XEN is mentioned here. Yes, it is 
auto-translated like DOMID_IO, but code doesn't care about that here.

The overall comment reads a bit odd without the implement for non-dom0. 
I don't have a good suggestion other than have a different comment for 
now and rewording it. But that's just churn.

Regarding the current comment I would suggest the following:

DOMID_IO is auto-translated (i.e. it seems RAM 1:1). So we do not need 
to create mapping in the P2M.

I would suggest to switch to BUG_ON() because this is init code. So 
better to be obvious.

Well, it would not be shared memory otherwise :). I think here you are 
referring to the fact that the owner may be DOMID_IO *and* the area 
still shared with multiple borrower.

I think it would be worth explaining in the commit message that DOMID_IO 
is not a "real" domain. This is why you need to check whether the shared 
area has been reserved. So how about replacing the two paragraphs with:

"DOMID_IO is a fake domain and is not described in the Device-Tree. 
Therefore When the owner of the shared region is DOMID_IO, we will only 
find the borrowers."

> +        {
> +            /* Allocate statically shared pages to the default owner dom_io. */

This is mostly repeating the line below. How about:

"We found the first borrower of the region, the owner was not specified 
so they should be assign to dom0".

> +            ret = allocate_shared_memory(dom_io, addr_cells, size_cells,
> +                                         pbase, psize);

While proposing some comments above, I realized that this function is 
not really allocating memory. It is assigning a set of pages to domain.

So may I suggest to rename it to assign_shared_memory()? Or maybe 
acquire_shared_memory()?

This is a very inefficient way for obtaining a count. On a large
system this loop is liable to take excessively long. I'm inclined
to say that even adding a call to process_pending_softirqs() isn't
going to make this work reasonably.

I'm also not convinced of having BUG_ON() in keyhandler functions
which are supposed to only dump state.

I question the consuming of a separate key for this purpose: What's
wrong with adding the functionality to dump_heap()?

Not as long as both use string_param(), true. They'd need to both become
custom_param(), doing at least some basic parsing right away.

without your multiple-serial-consoles change, so possibly not of
immediate need (unless someone comes forward expressing interest and
actually approving that change of yours).

I think setting this here is too late because "feature-persistent" was alre=
ady
written to xenstore via talk_to_blkback but with default 0. So during the
connect blkback will not see that the guest supports the feature and falls =
back
to no persistent grants.

Tested only this patch with some hacky dom0 kernel that doesn't have the pa=
tch
from your series yet. Will do more testing next week.

Applied to pci/misc for v6.1 with commit log below, thanks!

  PCI/MSI: Correct 'can_mask' test in msi_add_msi_desc()

  71020a3c0dff4 ("PCI/MSI: Use msi_add_msi_desc()") inadvertently reversed
  the sense of "msi_attrib.can_mask" in one use:

    - if (entry->pci.msi_attrib.can_mask) {
    -         addr = pci_msix_desc_addr(entry);
    -         entry->pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);
    + if (!desc.pci.msi_attrib.can_mask) {
    +         addr = pci_msix_desc_addr(&desc);
    +         desc.pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);

  Restore the original test.

We can definitely add a dynamic array of counters that get updated when
inserting a page in the colored heap so that we don't need to compute
anything here.

I'm also not convinced of having BUG_ON() in keyhandler functions

You're right. I'll remove that.

We didn't want to weigh on that functionality so much, but probably
having a separate key is even worse. If it's not a problem I'll merge
it in the dump_heap() function.

Thanks.

Appreciate for your test!  And you're right, this patch is not fixing the issue
completely.  That is, commit 402c43ea6b34 ("xen-blkfront: Apply
'feature_persistent' parameter when connect") introduced two bugs.  One is the
misuse of the semantic of the advertisement.  It's fixed by this patch.  The
second bug, which you found here, is caching the parameter in a wrong place.

In detail, blkfront does the advertisement before connect (for init and resume)
and then negotiation after connected.  And the blkback does the negotiation
first, and then the advertisement during the establishing the connection.
Hence, blkback should cache the parameter just before the negotiation logic
while blkfront should do that just before the advertisement logic.

The blkback behavior change commit (e94c6101e151) did the work in the right
place, but the blkfront behavior change commit didn't.

So, I guess below change would fix the issue entirely when applied together
with this patch.  Any opinion, please?

To be fair, I think we should say the misuse of the semantic issue came from
the initial commit[1] that uses only one field for the two different
information (availability of the feature and decision to use the feature), and
the mis-placed caching has introduced by the behavior change commit[2].

[1] 74a852479c68 ("xen-blkfront: add a parameter for disabling of persistent grants")
[2] 402c43ea6b34 ("xen-blkfront: Apply 'feature_persistent' parameter when connect")

This is the problem with going with a more sophisticated version of the
rule: it is not immediately obvious any longer. I have to read this
explanation three times to appreciate what it means, I don't think a new
contributor would really have any chances of getting this right,
especially as cppcheck/Eclair wouldn't be able to help them either.

FWIW, 'feature_persistent' variable definition should be moved to above of
'talk_to_blkback()'.  Otherwise, build would fail.

Changes since v1:

- Use a different type (struct xen_efi_mem_info) for memory information
  provided by Xen, as Xen reports it in a different way than the
  standard Linux functions do.

Indeed so, but making the bug happen much less frequently is still a
significant win for users.

In the long term, there is one situation I do not have a good solution
for: recovery from GUI agent crashes.  If the GUI agent crashes, the
kernel it is running under has two bad choices.  Either the kernel can
reclaim the grants, risking them being mapped at a later time by the GUI
daemon, or it can leak them, which is bad for obvious reasons.  I
believe the current implementation makes the former choice.

To fix this problem, I recommend the following changes:

1. Treat =E2=80=9Cbackend has not unmapped grant=E2=80=9D errors as non-fat=
al.  The most
   likely cause is buggy userspace software, not an attempt to exploit
   XSA-396.  Instead of disabling the device, just log a warning message
   and put the grant on the deferred queue.  Even leaking the grant
   would be preferable to the current behavior, as disabling a block
   device typically leaves the VM unusable.

2. Ensure that the same grant being mapped twice is handled correctly.
   At least Linux is known to have bugs in this regard.

3. Provide a means for a domain to be notified by Xen whenever one of
   its grants is unmapped.  Setting an event channel and writing to a
   shared ring would suffice.  This would allow eliminating the kludgy
   deferred freeing mechanism.

Hi All,

I tried to run vhost-user-i2c on X86 machine according to the page https://=
lists.gnu.org/archive/html/qemu-devel/2021-03/msg08379.html
The aim is to access i2c device from VM.

How can I pass the below arguments to boot the VM using xl tool? Which is t=
he recommended way to access i2c bus from VM on x86?
  -chardev socket,path=3Dvi2c.sock,id=3Dvi2c \
  -device vhost-user-i2c-pci,chardev=3Dvi2c,id=3Di2c

I tried to pass this arguments as below, but failed to boot the VM
device_model_args_hvm =3D [ "-chardev", "socket","path=3Dvi2c.sock0","id=3D=
vi2c" ]
device_model_args_hvm =3D [ "-device", "vhost-user-i2c-pci","chardev=3Dvi2c=
","id=3Di2c" ]

compiled  qemu with  the i2c-backend patch
./vhost-user-i2c --socket-path=3Dvi2c.sock --device-list 0:57

Hi Bertrand,

Thanks for your support!

As suggested, I enabled BLK_DEV_LOOP in the kernel & now I can see loop
devices in the "/dev" directory.
I could see xen-guest-image-minimal loading but at the end it's throwing
error *INIT: cannot execute "/sbin/getty-wrapper"*

I found start_getty in the image but getty-wrapper is not there. while
exploring source could see getty-wrapper in meta-virtualization sysvinit,
but start_getty is in poky sysvinit.
Any suggestions on this issue? Adding full logs below for reference:

&gt; No, I couldn&#39;t see /dev/loop0. Can you please guide me to create i=

<br>
First thing to try is =E2=80=9Cmodprobe loop&quot;<br>
<br>
It that does not work (ie module not found) you should check in your linux =
config if BLK_DEV_LOOP is enabled.<br>
<br>
&gt; <br>
&gt; I didn&#39;t change dom0 configurations, it&#39;s default generated by=
 yocto.<br>
&gt;=C2=A0 <br>
&gt; I will append this &quot;IMAGE_FSTYPES:append =3D &quot; wic.gz=E2=80=

&gt; I think you have a loop issue.<br>
&gt; <br>
&gt; Could you check if /dev/loop0 exists ?<br>
&gt; <br>
&gt; Did you change something on the dom0 linux configuration generated by =
Yocto ?<br>
&gt; <br>
&gt; We are using Yocto on RPI4 here without any issue like that, only diff=
erence with<br>
&gt; your setup is that we generate a wic image to have a real disk image i=
nstead of<br>
&gt; using the ext3/ext4 one.<br>
&gt; <br>
&gt; Should be possible to do the same on your side by adding the following=
 in local.conf:<br>
&gt; IMAGE_FSTYPES:append =3D &quot; wic.gz=E2=80=9D<br>
&gt; <br>
&gt; &gt; <br>
&gt; &gt; Even after removing &#39;type=3Dnetfront&#39; from vif it&#39;s f=
ailing. <br>
&gt; <br>
&gt; This option is only for hvm on x86, so you can remove it from your con=
figuration.<br>
&gt; <br>
&gt; &gt; One more doubt here, could this mac address be a dummy or actual =
here?<br>
&gt; <br>
&gt; This is a dummy one you set for the guest network interface and this i=
s the Mac<br>
&gt;=C2=A0 address other devices on your network will see so it must be ful=
ly valid (and<br>
&gt;=C2=A0 not conflicting with other devices on your network).<br>

&gt; &gt; You don&#39;t actually need to mount<br>
&gt; &gt; xen-guest-image-minimal-raspberrypi4-64.ext3 anywhere to use it t=
o run<br>
&gt; &gt; your guest VM with &quot;xl create&quot;. <br>
&gt; &gt; <br>
&gt; &gt; It is enough to do this instead, as Bertrand suggested:<br>
&gt; &gt; <br>
&gt; &gt; disk=3D[&quot;file:/path/to/file/xen-guest-image-minimal-raspberr=
ypi4-64.ext3,xvda,w&quot;]<br>
&gt; &gt; <br>

+Acquire resource reference
+==========================
+
+Acquire resource allows you to share a resource between Xen and dom0.
+Resources are generally represented by pages that are mapped into user-space.
+These pages are accessed by Xen and belong to a domU. This document describes
+the api to build tools to access these resources. The document also describes
+the software components required to create and expose a domain's resource. This
+is not a tutorial or a how-to guide. It merely describes the machinery that is
+already described in the code itself.
+
+.. warning::
+
+    The code in this document may already be out of date, however it may
+    be enough to illustrate how the acquire resource interface works.
+
+
+Tool API
+-----------
+
+This section describes the api to map a resource in a user-space tool in dom0.
+The api is based on the following functions:
+
+* xenforeignmemory_open()
+
+* xenforeignmemory_resource_size()
+
+* xenforeignmemory_map_resource()
+
+* xenforeignmemory_unmap_resource()
+
+The ``xenforeignmemory_open()`` function gets the handler that is used by the
+rest of the functions:
+
+.. code-block:: c
+
+   fh = xenforeignmemory_open(NULL, 0);
+
+The ``xenforeignmemory_resource_size()`` function gets the size of the resource.
+For example, in the following code, we get the size of the
+``XENMEM_RESOURCE_VMTRACE_BUF``:
+
+.. code-block:: c
+
+    rc = xenforeignmemory_resource_size(fh, domid, XENMEM_resource_vmtrace_buf, vcpu, &size);
+
+The size of the resource is returned in ``size`` in bytes.
+
+The ``xenforeignmemory_map_resource()`` function maps a domain's resource. The
+function is declared as follows:
+
+.. code-block:: c
+
+    xenforeignmemory_resource_handle *xenforeignmemory_map_resource(
+        xenforeignmemory_handle *fmem, domid_t domid, unsigned int type,
+        unsigned int id, unsigned long frame, unsigned long nr_frames,
+        void **paddr, int prot, int flags);
+
+The size of the resource is in number of frames. For example, **QEMU** uses it
+to map the ioreq server between the domain and QEMU:
+
+.. code-block:: c
+
+    fres = xenforeignmemory_map_resource(xen_fmem, xen_domid, XENMEM_resource_ioreq_server,
+         state->ioservid, 0, 2, &addr, PROT_READ | PROT_WRITE, 0);
+
+
+The third parameter corresponds with the resource that we request from the
+domain, e.g., ``XENMEM_resource_ioreq_server``. The seventh parameter returns a
+pointer-to-pointer to the address of the mapped resource.
+
+Finally, the ``xenforeignmemory_unmap_resource()`` function unmaps the region:
+
+.. code-block:: c
+    :caption: tools/misc/xen-vmtrace.c
+
+    if ( fres && xenforeignmemory_unmap_resource(fh, fres) )
+        perror("xenforeignmemory_unmap_resource()");
+
+Exposing a domain's resource
+---------------------------------
+
+In this section, we describe how to build a new resource and expose it to dom0.
+Resources are defined in ``xen/include/public/memory.h``. In Xen-4.16, there
+are three resources:
+
+.. code-block:: c
+    :caption: xen/include/public/memory.h
+
+    #define XENMEM_resource_ioreq_server 0
+    #define XENMEM_resource_grant_table 1
+    #define XENMEM_resource_vmtrace_buf 2
+
+The ``resource_max_frames()`` function returns the size of a resource. The
+resource may provide a handler to get the size. This is the definition of the
+``resource_max_frame()`` function:
+
+.. code-block:: c
+    :linenos:
+    :caption: xen/common/memory.c
+
+    static unsigned int resource_max_frames(const struct domain *d,
+                                            unsigned int type, unsigned int id)
+    {
+        switch ( type )
+        {
+        case XENMEM_resource_grant_table:
+            return gnttab_resource_max_frames(d, id);
+
+        case XENMEM_resource_ioreq_server:
+            return ioreq_server_max_frames(d);
+
+        case XENMEM_resource_vmtrace_buf:
+            return d->vmtrace_size >> PAGE_SHIFT;
+
+        default:
+            return -EOPNOTSUPP;
+        }
+    }
+
+The ``_acquire_resource()`` function invokes the corresponding handler that maps
+the resource. The handler relies on ``type`` to select the correct handler:
+
+.. code-block:: c
+    :linenos:
+    :caption: xen/common/memory.c
+
+    static int _acquire_resource(
+        struct domain *d, unsigned int type, unsigned int id, unsigned int frame,
+        unsigned int nr_frames, xen_pfn_t mfn_list[])
+    {
+        switch ( type )
+        {
+        case XENMEM_resource_grant_table:
+            return gnttab_acquire_resource(d, id, frame, nr_frames, mfn_list);
+
+        case XENMEM_resource_ioreq_server:
+            return acquire_ioreq_server(d, id, frame, nr_frames, mfn_list);
+
+        case XENMEM_resource_vmtrace_buf:
+            return acquire_vmtrace_buf(d, id, frame, nr_frames, mfn_list);
+
+        default:
+            return -EOPNOTSUPP;
+        }
+    }
+
+Note that if a new resource has to be added, these two functions need to be
+modified. These handlers have the common declaration:
+
+.. code-block:: c
+    :linenos:
+    :caption: xen/common/memory.c
+
+    static int acquire_vmtrace_buf(
+        struct domain *d, unsigned int id, unsigned int frame,
+        unsigned int nr_frames, xen_pfn_t mfn_list[])
+    {
+
+The function returns in ``mfn_list[]`` a number of ``nr_frames`` of pointers to
+mfn pages. These pages are designed to be mapped contiguously. For example, for
+the ``XENMEM_resource_vmtrace_buf`` resource, the handler is defined as
+follows:
+
+.. code-block:: c
+    :linenos:
+    :caption: xen/common/memory.c
+
+    static int acquire_vmtrace_buf(
+        struct domain *d, unsigned int id, unsigned int frame,
+        unsigned int nr_frames, xen_pfn_t mfn_list[])
+    {
+        const struct vcpu *v = domain_vcpu(d, id);
+        unsigned int i;
+        mfn_t mfn;
+
+        if ( !v )
+            return -ENOENT;
+
+        if ( !v->vmtrace.pg ||
+             (frame + nr_frames) > (d->vmtrace_size >> PAGE_SHIFT) )
+            return -EINVAL;
+
+        mfn = page_to_mfn(v->vmtrace.pg);
+
+        for ( i = 0; i < nr_frames; i++ )
+            mfn_list[i] = mfn_x(mfn) + frame + i;
+
+        return nr_frames;
+    }
+
+Note that the handler only returns the mfn pages that have been previously
+allocated in ``vmtrace.pg``. The allocation of the resource happens during the
+instantiation of the vcpu. A set of pages is allocated during the instantiation
+of each vcpu. For allocating the page, we use the domheap with the
+``MEMF_no_refcount`` flag:
+
+.. code-block:: c
+
+    v->vmtrace.pg = alloc_domheap_page(s->target, MEMF_no_refcount);
+
+This allocates a page with the `PGC_allocated` bit set and a single reference
+count. Then, we grab a general reference count as well as a writable type count,
+so that it does not get used as a special page.
+
+.. code-block:: c
+
+    for ( i = 0; i < (d->vmtrace_size >> PAGE_SHIFT); i++ )
+        if ( unlikely(!get_page_and_type(&pg[i], d, PGT_writable_page)) )
+            /*
+             * The domain can't possibly know about this page yet, so failure
+             * here is a clear indication of something fishy going on.
+             */
+            goto refcnt_err;
+
+To access the pages in the context of Xen, we map the page by
+using:
+
+.. code-block:: c
+
+    va_page = __map_domain_page_global(page);
+
+The ``va_page`` pointer is used in the context of Xen.
+
+To release the page, we first unmap the frame with ``unmap_domheap_map()``, and we drop first the allocation and second the own type count, thus:
+
+.. code-block:: c
+
+    put_page_alloc_ref(pg);
+    put_page_and_type(pg);
+
+Note that we cannot free the page until all references have dropped and that includes the reference from tools in dom0. The ``put_page()`` brings the reference count to 0 thus automatically freeing the page.
+
+Acquire Resources
+-----------------
+
+This section briefly describes the resources that rely on the acquire resource
+interface. These resources are mapped by tools like QEMU.
+
+Intel Processor Trace (IPT)
+```````````````````````````
+
+This resource is named ``XENMEM_resource_vmtrace_buf`` and its size in bytes is
+set in ``d->vmtrace_size``. It contains the traces generated by the IPT. These
+traces are generated by each vcpu. The pages are allocated during
+``vcpu_create()``. The pages are stored in the ``vcpu`` structure in
+``sched.h``:
+
+.. code-block:: c
+
+   struct {
+        struct page_info *pg; /* One contiguous allocation of d->vmtrace_size */
+    } vmtrace;
+
+During ``vcpu_create()``, the pg is allocated by using the per-domain heap:
+
+.. code-block:: c
+
+    pg = alloc_domheap_pages(d, get_order_from_bytes(d->vmtrace_size), MEMF_no_refcount);
+
+For a given vcpu, the page is loaded into the guest at
+``vmx_restore_guest_msrs()``:
+
+.. code-block:: c
+    :caption: xen/arch/x86/hvm/vmx/vmx.c
+
+    wrmsrl(MSR_RTIT_OUTPUT_BASE, page_to_maddr(v->vmtrace.pg));
+
+The releasing of the pages happens during the vcpu teardown.
+
+Grant Table
+```````````
+
+The grant tables are represented by the ``XENMEM_resource_grant_table``
+resource. Grant tables are special since guests can map grant tables. Dom0 also
+needs to write into the grant table to set up the grants for xenstored and
+xenconsoled. When acquiring the resource, the pages are allocated from the xen
+heap in ``gnttab_get_shared_frame_mfn()``:
+
+.. code-block:: c
+    :linenos:
+    :caption: xen/common/grant_table.c
+
+    gt->shared_raw[i] = alloc_xenheap_page()
+    share_xen_page_with_guest(virt_to_page(gt->shared_raw[i]), d, SHARE_rw);
+
+Then, pages are shared with the guest. These pages are then converted from virt
+to mfn before returning:
+
+.. code-block:: c
+    :linenos:
+
+    for ( i = 0; i < nr_frames; ++i )
+         mfn_list[i] = virt_to_mfn(vaddrs[frame + i]);
+
+Ioreq server
+````````````
+
+The ioreq server is represented by the ``XENMEM_resource_ioreq_server``
+resource. An ioreq server provides emulated devices to HVM and PVH guests. The
+allocation is done in ``ioreq_server_alloc_mfn()``. The following code partially
+shows the allocation of the pages that represent the ioreq server:
+
+.. code-block:: c
+    :linenos:
+    :caption: xen/common/ioreq.c
+
+    page = alloc_domheap_page(s->target, MEMF_no_refcount);
+
+    iorp->va = __map_domain_page_global(page);
+    if ( !iorp->va )
+        goto fail;
+
+    iorp->page = page;
+    clear_page(iorp->va);
+    return 0;
+
+The function above is invoked from ``ioreq_server_get_frame()`` which is called
+from ``acquire_ioreq_server()``. For acquiring, the function returns the
+allocated pages as follows:
+
+.. code-block:: c
+
+    *mfn = page_to_mfn(s->bufioreq.page);
+
+The ``ioreq_server_free_mfn()`` function releases the pages as follows:
+
+.. code-block:: c
+    :linenos:
+    :caption: xen/common/ioreq.c
+
+    unmap_domain_page_global(iorp->va);
+    iorp->va = NULL;
+
+    put_page_alloc_ref(page);
+    put_page_and_type(page);

Then why change at all? Since you can configure only one (dbgp=3Dehci _or_
dbgp=3Dxhci), then there is not ambiguity what "console=3Ddbgp" means.
Separating SERHND_DBC from SERHND_DBGP would IMO make sense only if you
can actually use them both (even if not both for console, but for
example one for debugger).

Or do you mean to use custom_param() to actually make "dbgp=3Dxhci
dbgp=3Dehci" working? But then IMO having "console=3Ddbgp console=3Ddbc" wo=
uld
be confusing, as "dbc" has no obvious relation to neither side of
"dbgp=3Dxhci". Maybe use "console=3Dxhci" then?

I'll limit the description to the relevant minimum here.
The gui-agent(*) uses gntalloc to share framebuffers (they are allocated
whenever an application within domU opens a window), then sends grant
reference numbers over vchan to the gui-daemon (running in dom0 by
default, but it can be also another domU).
Then the gui-daemon(*) maps them.
Later, when an application closes a window, the shared memory is
unmapped, and gui-daemon is informed about it. Releasing grant refs is
deferred by the kernel (until gui-daemon unmaps them). It may happen
that unmapping on the gui-agent side will happen before gui-daemon maps
them. We are modifying our GUI protocol to delay releasing grants on the
user space side, to coordinate with gui-daemon (basically wait until
gui-daemon confirms it unmapped them). This should fix the "normal"
case.
But if the gui-agent crashes just after sending grant refs, but before
gui-daemon maps them, then the problem is still there. If they are
immediately released by the kernel for others to use, we can hit the
same issue again (for example blkfront using them, and then gui-daemon
mapping them). I don't see race-free method for solving this with the
current API. GUI daemon can notice when such situation happens (by
checking if gui-agent is still alive after mapping grants), but that is
too late already.

The main difference compared to kernel drivers is the automatic release
on crash (or other unclean exit). In case of kernel driver crash, either
the whole VM goes down, or at least automatic release doesn't happen.
Maybe gntalloc could have some flag (per open file? per allocated
grant?) to _not_ release grant reference (aka leak it) in case of
implicit unmap, instead of explicit release? Such explicit release
would need to be added to the Linux gntshr API, as xengntshr_unshare()
currently is just munmap()). I don't see many other options to avoid
userspace crash (potentially) taking down PV device with it too...


(*) gui-agent and gui-daemon here are both in fact two processes (qubes gui
process that handles vchan communication and Xorg that does the actual
mapping). It complicates few things, but generally is irrelevant detail
=66rom the Xen point of view.

Subject: [PATCH] xen-pcifront: Handle missed Connected state
Date: Mon, 29 Aug 2022 11:15:36 -0400
Message-Id: <20220829151536.8578-1-jandryuk@gmail.com>
X-Mailer: git-send-email 2.37.2
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

An HVM guest with linux stubdom and 2 PCI devices failed to start as
libxl timed out waiting for the PCI devices to be added.  It happens
intermittently but with some regularity.  libxl wrote the two xenstore
entries for the devices, but then timed out waiting for backend state 4
(Connected) - the state stayed at 7 (Reconfiguring).  (PCI passthrough
to an HVM with stubdomain is PV passthrough to the stubdomain and then
HVM passthrough with the QEMU inside the stubdomain.)

The stubdom kernel never printed "pcifront pci-0: Installing PCI
frontend", so it seems to have missed state 4 which would have
called pcifront_try_connect -> pcifront_connect_and_init_dma

Have pcifront_detach_devices special-case state Initialised and call
pcifront_connect_and_init_dma.  Don't use pcifront_try_connect because
that sets the xenbus state which may throw off the backend.  After
connecting, skip the remainder of detach_devices since none have been
initialized yet.  When the backend switches to Reconfigured,
pcifront_attach_devices will pick them up again.

That is still less than great, as it leads to a memory leak.  Another
approach would be some sort of unmap/revoke operation in the backend, so
that the backend revokes its own access to the grants before telling the
frontend it has unmapped them.  This would cause the userspace mmap()
call to fail.

In this case, the grants are being mapped read-only, so (unless I have
missed something) data corruption is not possible.

At least in the GUI case, large numbers of grants are typically unmapped
at once, and a notification is only necessary when the entire block has
been unmapped.  This should mitigate the performance concerns.

In Qubes OS, this happens so often that we had to patch the Linux kernel
to handle it better.  Prior to the patch, the background deferred
reclaim could not keep up, causing a memory leak.  Furthermore, the log
messages whenever an unmap had to be deferred were flooding the logs.
While we could change the GUI protocol to provide an unmap-time
notification, this is only because we use an LD_PRELOAD hack to hook
Xorg=E2=80=99s unmapping calls.  I would prefer to not continue to rely on =
this.

I would choose a different name for the property not to be confused with
a domain's xen,static-mem property which is for a different purpose: the
memory of the domain.

---

- xen,static-heap

    Property under the top-level "chosen" node. It specifies the address
    and size of Xen reserved heap memory.


- #xen,static-heap-address-cells and #xen,static-heap-size-cells

    Specify the number of cells used for the address and size of the
    xen,static-heap property under "chosen".

I would keep the < 1 check but it doesn't make much difference either

Subject: USB-C 250GB SSD Passthrough fails to DomU Ubuntu

Hi All

On XEN-4.16 with Ubuntu 22.04 Dom0 and HVM-DomU, I tried to do a USB mass
storage device passthrough to DomU.
I followed the PVUSB method mentioned in
https://wiki.xenproject.org/wiki/Xen_USB_Passthrough.

I am able to do passthrough for USB 2.0 and 3.x version 32/64 GB mass
storage devices to DomU.
Passthrough failed for "SanDisk 250GB SSD USB-C, USB 3.1" with below error.
Able to access the SSD in Dom0.
Can someone help with what could be missing here.

*Commands used:*
host$ sudo xl usbctrl-attach vm1 version=3 ports=6
host$ sudo xl usbdev-attach vm1 hostbus=3 hostaddr=2

*Error Log in DomU*
VM1:~$ sudo dmesg

This is what I think would be better but maintainers will have a decisive vote.

This is totally fine. What I mean is that the check you introduced does not correspond
to the panic message below. In case of reserved heap, its size is selected by the user.
"Not enough space for xenheap" means that there is not enough space to be reserved for heap,
meaning its size is too large. But your check is about size being too small.

FWICS, reserved_heap will be set to true even if a user describes an empty region
for reserved heap. This cannot be consider a properly defined region for a heap.

Few more logs

>From Dom0, did passthrough of two USB drives (32GB stick and 250GB USB SDD)
In DomU, 32GB driver got mounted but 250GB SSD fails to mount.
In DomU, "lsusb" shows both the drives but "usb-devices" shows only the
32GB drive.

I agree with this.

> and we can automatically calculate xenheap_pages in a single line.

Here I am a little bit confused. Sorry to ask but could you please explain
a little bit more about why we can calculate the xenheap_pages in a single
line? Below is the code snippet in my mind, is this correct?

if (reserved_heap)
    e =3D reserved_heap_end;
else
{
    do
    {
        e =3D consider_modules(ram_start, ram_end,
                             pfn_to_paddr(xenheap_pages),
                             32<<20, 0);
        if ( e )
            break;

        xenheap_pages >>=3D 1;
    } while ( !opt_xenheap_megabytes && xenheap_pages > 32<<(20-PAGE_SHIFT)=
 );
}

Ack.

But your check is against heap being to small (less than 32M).
So basically if the following check fails:
"( reserved_heap && reserved_heap_pages < 32<<(20-PAGE_SHIFT) ) )"
it means that the heap region defined by a user is too small (not too large),
because according to requirements it should be at least 32M.

Ok, it clearly depends on the way someone understands this sentence.
Currently this panic can be triggered if the heap size is too large and
should be read as "heap is too large to fit in because there is not enough space
within RAM considering modules (e - s < size)". Usually (and also in this case)
space refers to a region to contain another one.

You are reusing the same message for different meaning, that is "user defined too
small heap and this space (read as size) is not enough".

Let's leave it to someone else to decide.

Hello guys,

The same issue migh be found by link
https://xen.markmail.org/message/3w4oqeu5z7ryfbsb?q=xen_add_phys_to_mach_entry&page=1

DOM0/DOMU kernels version 5.15.19

Two XENified guests. They are equal. They both have the same configuration.
It is enough to have one DomU and Dom0.

Part of DomU configuration.
type = "pvh"
memory = 1024
vcpus = 1

It is not necessary to repeat full custom board configuration with all the
bridges.
It is enough to connect DomU with some external machine or with Dom0
through the network.

You should have a perf3 compiled package on both ends.
on Dom0 or external host you issue command:
perf3 -s &

on DomU you issue the command:
perf3 -c [Dom0 or external host ip address] -k 400K -b 0

After enough short time you will see in your DomU kernel messages or in
your xen console something like
[ 2385.999011] xen_add_phys_to_mach_entry: cannot add
pfn=0x000000000003e0de -> mfn=0x00000000008031f2: pfn=0x000000000003e0de ->

mfn=0x00000000008032a7 already exists

You will have a lot of those messages.

Involved files
arch/arm/xen/p2m.c
drivers/net/xen-netback/netback.c
drivers/net/xen-netback/common.h

This problem arrived in the p2m.c file in the xen_add_phys_to_mach_entry
function
This function adds a new mapping XEN page pfn to the DomU gfn.
It does via red/black tree
Xen netback adapter structure placed in the common.h file. It contains
xenvif_queue structure.
There are some involved members from this structure.

struct xenvif_queue {
...
struct page *mmap_pages[MAX_PENDING_REQS];
pending_ring_idx_t pending_cons;
...
u16 pending_ring[MAX_PENDING_REQS];
...
struct page *pages_to_map[MAX_PENDING_REQS];
...
}

All the pages are stored in the xenvif_queue->mmap_pages
They are allocated by their indexes. Those ones are stored
sequentially in the xenvif_queue->pending_ring.
Pages allocation depends on xenvif_queue->pending_cons.
This value rounded up to MAX_PENDING_REQS value.
Pages allocated for the request cyclically.
When an intensive network traffic is in progress especially
when a packets flow density has been growing, sooner or later
we will run into the case when we do not have enough free pages.
MAX_PENDING_REQS in our case is 256
This case arrives in the netback.c xenvif_tx_action->gnttab_map_refs call.
Main work is in the xenvif_tx_build_gops.
xenvif_tx_action is issued in NAPI context.
So we could say it is something like the interrupt bottom half.
This message is produced when the issued pfn is presented in the red/black
tree.
It is produced unconditionally. In  the above mentioned condition this
output
degrades the performance drastically.
I may offer a patch which decreases the amount of messages.

Regards,
Oleg

Yes, this is what I meant.

But also, here the loop is also for adjusting xenheap_pages, and
xenheap_pages is initialized as follows:


    if ( opt_xenheap_megabytes )
        xenheap_pages = opt_xenheap_megabytes << (20-PAGE_SHIFT);
    else
    {
        xenheap_pages = (heap_pages/32 + 0x1fffUL) & ~0x1fffUL;
        xenheap_pages = max(xenheap_pages, 32UL<<(20-PAGE_SHIFT));
        xenheap_pages = min(xenheap_pages, 1UL<<(30-PAGE_SHIFT));
    }


In the reserved_heap case, it doesn't make sense to initialize
xenheap_pages like that, right? It should be something like:

    if ( opt_xenheap_megabytes )
        xenheap_pages = opt_xenheap_megabytes << (20-PAGE_SHIFT);
    else if ( reserved_heap )
        xenheap_pages = heap_pages;
    else
    {
        xenheap_pages = (heap_pages/32 + 0x1fffUL) & ~0x1fffUL;
        xenheap_pages = max(xenheap_pages, 32UL<<(20-PAGE_SHIFT));
        xenheap_pages = min(xenheap_pages, 1UL<<(30-PAGE_SHIFT));
    }

But also it looks like that on arm32 we have specific requirements for
Xen heap:

     *  - must be 32 MiB aligned
     *  - must not include Xen itself or the boot modules
     *  - must be at most 1GB or 1/32 the total RAM in the system if less
     *  - must be at least 32M

I think we should check at least the 32MB alignment and 32MB minimum
size before using the xen_heap bank.


In short I think this patch should:

- add a check for 32MB alignment and size of the xen_heap memory bank
- if reserved_heap, set xenheap_pages = heap_pages
- if reserved_heap, skip the consider_modules do/while

Does it make sense?

I think we should have a separate check specific for the device tree
input parameters to make sure the region is correct, that way we can
have a specific error message, such as:

"xen,static-heap address needs to be 32MB aligned and the size a
multiple of 32MB."

I don't have a strong preference and the way the current code is
written, it would actually take less memory as is (the extra bool
xen_heap comes for free.)

I would keep the patch as is for now and for 4.17.

If Julien prefers a refactoring of bootinfo/meminfo I think it could be
done after the release if you are up to it.

Subject: [PATCH] acpi: Add TPM2 interface definition and make the TPM version configurable.
Date: Tue, 30 Aug 2022 20:27:06 +0000
Message-ID: <20220830202706.1618386-1-jennifer.herbert@citrix.com>
X-Mailer: git-send-email 2.31.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Content-Type: text/plain

This patch introduces an optional TPM 2 interface definition to the ACPI table,
which is to be used as part of a vTPM 2 implementation.
To enable the new interface - I have made the TPM interface version
configurable in the acpi_config, with the default being the existing 1.2.(TCPA)
I have also added to hvmloader an option to utilise this new config, which can
be triggered by setting the platform/tpm_verion xenstore key.

Subject: [PATCH v2] xen/device_tree: Fix MISRA C 2012 Rule 20.7 violations
Date: Tue, 30 Aug 2022 23:48:18 +0300
Message-Id: <20220830204818.1374930-1-burzalodowa@gmail.com>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Add parentheses around the macro parameters that are used as expressions
to prevent against unintended expansions during macro substitution.

Signed-off-by: Xenia Ragiadakou <burzalodowa@gmail.com>
---

Changes in v2:
- apply rule 20.7 as is, without deviating from it
- adjust commit message accordingly

Also, in this file, the macro dt_irq(irq) has not been defined properly but
since it is not used, the bug has not been uncovered yet.
I can either fix it or remove it along with macro dt_irq_flags(irq) under
rule 2.5 "A project should not contain unused macro declarations" (advisory)

Thank you very much for your detailed explanation below!

I am not sure about that, since we already have
heap_pages =3D reserved_heap ? reserved_heap_pages : ram_pages;

the heap_pages is supposed to contain domheap_pages + xenheap_pages
based on the reserved heap definition discussed in the RFC.

from the code in...

>=20
>     if ( opt_xenheap_megabytes )
>         xenheap_pages =3D opt_xenheap_megabytes << (20-PAGE_SHIFT);

...here, setting xenheap_pages to heap_pages makes me a little bit
confused.

If we keep this logic as this patch does, we can have the requirements...

>      *  - must be at least 32M

...here, with the "1/32 the total RAM" now being "1/32 of the total reserve=
d
heap region", since heap_pages is now reserved_heap_pages.

I left some of my thoughts above to explain my understanding, but I might
be wrong, thank you for your patience!

Kind regards,

To add a little bit more about the background, here is the RFC discussion [=

I should have attached this in my previous reply, sorry.

Subject: [PATCH v11 1/6] xen: do not free reserved memory into heap

Pages used as guest RAM for static domain, shall be reserved to this
domain only.
So in case reserved pages being used for other purpose, users
shall not free them back to heap, even when last ref gets dropped.

This commit introduces a new helper free_domstatic_page to free
static page in runtime, and free_staticmem_pages will be called by it
in runtime, so let's drop the __init flag.

Wrapper #ifdef CONFIG_STATIC_MEMORY around function declaration(
free_staticmem_pages, free_domstatic_page, etc) is kinds of redundant,
so we decide to remove it here.

- move free_domheap_page into else-condition
- considering scrubbing static pages, domain dying case and opt_scrub_domheap
both donot apply to static pages.
- as unowned static pages don't make themselves to free_domstatic_page
at the moment, remove else-condition and add ASSERT(d) at the top of the
function

- let put_page call free_domstatic_page for static page, when last ref
drops
- #define PGC_static zero when !CONFIG_STATIC_MEMORY, as it is used

v7 changes:
- protect free_staticmem_pages with heap_lock to match its reverse function
acquire_staticmem_pages
---
v6 changes:
- adapt to PGC_static
- remove #ifdef aroud function declaration
---
v5 changes:
- In order to avoid stub functions, we #define PGC_staticmem to non-zero only
when CONFIG_STATIC_MEMORY
- use "unlikely()" around pg->count_info & PGC_staticmem
- remove pointless "if", since mark_page_free() is going to set count_info
to PGC_state_free and by consequence clear PGC_staticmem
- move #define PGC_staticmem 0 to mm.h
---
v4 changes:
- no changes
---
v3 changes:
- fix possible racy issue in free_staticmem_pages()
- introduce a stub free_staticmem_pages() for the !CONFIG_STATIC_MEMORY case
- move the change to free_heap_pages() to cover other potential call sites
- fix the indentation

v2 changes:
- new commit

Subject: [PATCH v11 0/6] populate/unpopulate memory when domain on static allocation
Date: Wed, 31 Aug 2022 10:40:35 +0800
Message-Id: <20220831024041.468757-1-Penny.Zheng@arm.com>
X-Mailer: git-send-email 2.25.1
MIME-Version: 1.0

Today when a domain unpopulates the memory on runtime, they will always
hand the memory over to the heap allocator. And it will be a problem if it
is a static domain.
Pages used as guest RAM for static domain shall always be reserved to this
domain only, and not be used for any other purposes, so they shall never go
back to heap allocator.

This patch serie intends to fix this issue, by adding pages on the new list
resv_page_list after having taken them off the "normal" list, when unpopulating
memory, and retrieving pages from resv page list(resv_page_list) when
populating memory.

---
v11 changes:
- printing message ahead of the assertion, which should also be
XENLOG_G_* kind of log level
- commit message tweak
- move "xen: rename free_staticmem_pages to unprepare_staticmem_pages" ahead
of "xen: retrieve reserved pages on populate_physmap"
- with assignment having failed and the page not exposed to the guest at any
point, there is no need for scrubbing
---
v10 changes:
- let Arm keep #define PGC_static 0 private, with the generic fallback
remaining in page_alloc.c
- change ASSERT(d) to ASSERT_UNREACHABLE() to be more robust looking
forward, and also add a printk() to log the problem
- mention the the removal of #ifdef CONFIG_STATIC_MEMORY in commit
message
- commit message typo fix
- Do not skip the list addition in that one special case
- add lock on the fail path
- new commit "xen: rename free_staticmem_pages to unprepare_staticmem_pages"
---
v9 changes:
- move free_domheap_page into else-condition
- considering scrubbing static pages, domain dying case and opt_scrub_domheap
both do not apply to static pages.
- as unowned static pages don't make themselves to free_domstatic_page
at the moment, remove else-condition and add ASSERT(d) at the top of the
function
- remove macro helper put_static_page, and just expand its code inside
free_domstatic_page
- Use ASSERT_ALLOC_CONTEXT() in acquire_reserved_page
- Add free_staticmem_pages to undo prepare_staticmem_pages when
assign_domstatic_pages fails
- Remove redundant static in error message
---
v8 changes:
- introduce new helper free_domstatic_page
- let put_page call free_domstatic_page for static page, when last ref
drops
- #define PGC_static zero when !CONFIG_STATIC_MEMORY, as it is used
outside page_alloc.c
- #ifdef-ary around is_domain_using_staticmem() is not needed anymore
- order as a parameter is not needed here, as all staticmem operations are
limited to order-0 regions
- move d->page_alloc_lock after operation on d->resv_page_list
- As concurrent free/allocate could modify the resv_page_list, we still
need the lock
---
v7 changes:
- protect free_staticmem_pages with heap_lock to match its reverse function
acquire_staticmem_pages
- IS_ENABLED(CONFIG_STATIC_MEMORY) would not be needed anymore
- add page on the rsv_page_list *after* it has been freed
- remove the lock, since we add the page to rsv_page_list after it has
been totally freed.
---
v6 changes:
- rename PGC_staticmem to PGC_static
- remove #ifdef aroud function declaration
- use domain instead of sub-systems
- move non-zero is_domain_using_staticmem() from ARM header to common
header
- move PGC_static !CONFIG_STATIC_MEMORY definition to common header
- drop the lock before returning
---
v5 changes:
- introduce three new commits
- In order to avoid stub functions, we #define PGC_staticmem to non-zero only
when CONFIG_STATIC_MEMORY
- use "unlikely()" around pg->count_info & PGC_staticmem
- remove pointless "if", since mark_page_free() is going to set count_info
to PGC_state_free and by consequence clear PGC_staticmem
- move #define PGC_staticmem 0 to mm.h
- guard "is_domain_using_staticmem" under CONFIG_STATIC_MEMORY
- #define is_domain_using_staticmem zero if undefined
- extract common codes for assigning pages into a helper assign_domstatic_pages
- refine commit message
- remove stub function acquire_reserved_page
- Alloc/free of memory can happen concurrently. So access to rsv_page_list
needs to be protected with a spinlock
---
v4 changes:
- commit message refinement
- miss dropping __init in acquire_domstatic_pages
- add the page back to the reserved list in case of error
- remove redundant printk
- refine log message and make it warn level
- guard "is_domain_using_staticmem" under CONFIG_STATIC_MEMORY
- #define is_domain_using_staticmem zero if undefined
---
v3 changes:
- fix possible racy issue in free_staticmem_pages()
- introduce a stub free_staticmem_pages() for the !CONFIG_STATIC_MEMORY case
- move the change to free_heap_pages() to cover other potential call sites
- change fixed width type uint32_t to unsigned int
- change "flags" to a more descriptive name "cdf"
- change name from "is_domain_static()" to "is_domain_using_staticmem"
- have page_list_del() just once out of the if()
- remove resv_pages counter
- make arch_free_heap_page be an expression, not a compound statement.
- move #ifndef is_domain_using_staticmem to the common header file
- remove #ifdef CONFIG_STATIC_MEMORY-ary
- remove meaningless page_to_mfn(page) in error log
---
v2 changes:
- let "flags" live in the struct domain. So other arch can take
advantage of it in the future
- change name from "is_domain_on_static_allocation" to "is_domain_static()"
- put reserved pages on resv_page_list after having taken them off
the "normal" list
- introduce acquire_reserved_page to retrieve reserved pages from
resv_page_list
- forbid non-zero-order requests in populate_physmap
- let is_domain_static return ((void)(d), false) on x86
- fix coding style

Today when a domain unpopulates the memory on runtime, they will always
hand the memory back to the heap allocator. And it will be a problem if domain
is static.

Pages as guest RAM for static domain shall be reserved to only this domain
and not be used for any other purposes, so they shall never go back to heap
allocator.

This commit puts reserved page on the new list resv_page_list after
it has been freed.

Subject: [PATCH v11 4/6] xen: introduce prepare_staticmem_pages
Date: Wed, 31 Aug 2022 10:40:39 +0800
Message-Id: <20220831024041.468757-5-Penny.Zheng@arm.com>
X-Mailer: git-send-email 2.25.1
In-Reply-To: <20220831024041.468757-1-Penny.Zheng@arm.com>

Later, we want to use acquire_domstatic_pages() for populating memory
for static domain on runtime, however, there are a lot of pointless work
(checking mfn_valid(), scrubbing the free part, cleaning the cache...)
considering we know the page is valid and belong to the guest.

This commit splits acquire_staticmem_pages() in two parts, and
introduces prepare_staticmem_pages to bypass all "pointless work".

The name of free_staticmem_pages is inappropriate, considering it is
the opposite of function prepare_staticmem_pages.

Rename free_staticmem_pages to unprepare_staticmem_pages.

Subject: [PATCH v11 6/6] xen: retrieve reserved pages on populate_physmap
Date: Wed, 31 Aug 2022 10:40:41 +0800

When a static domain populates memory through populate_physmap at runtime,
it shall retrieve reserved pages from resv_page_list to make sure that
guest RAM is still restricted in statically configured memory regions.
This commit also introduces a new helper acquire_reserved_page to make it work.

Signed-off-by: Penny Zheng <penny.zheng@arm.com>
---
v11 change:
- with assignment having failed and the page not exposed to the guest at any
point, there is no need for scrubbing
---
v10 changes:
- add lock on the fail path
---
v9 changes:
- Use ASSERT_ALLOC_CONTEXT() in acquire_reserved_page
- Add free_staticmem_pages to undo prepare_staticmem_pages when
assign_domstatic_pages
- Remove redundant static in error message
---
v8 changes:
- As concurrent free/allocate could modify the resv_page_list, we still
need the lock
---
v7 changes:
- remove the lock, since we add the page to rsv_page_list after it has
been totally freed.
---
v6 changes:
- drop the lock before returning
---
v5 changes:
- extract common codes for assigning pages into a helper assign_domstatic_pages
- refine commit message
- remove stub function acquire_reserved_page
- Alloc/free of memory can happen concurrently. So access to rsv_page_list
needs to be protected with a spinlock
---
v4 changes：
- miss dropping __init in acquire_domstatic_pages
- add the page back to the reserved list in case of error
- remove redundant printk
- refine log message and make it warn level
---
v3 changes:
- move is_domain_using_staticmem to the common header file
- remove #ifdef CONFIG_STATIC_MEMORY-ary
- remove meaningless page_to_mfn(page) in error log
---
v2 changes:
- introduce acquire_reserved_page to retrieve reserved pages from
resv_page_list
- forbid non-zero-order requests in populate_physmap
- let is_domain_static return ((void)(d), false) on x86

From: Kent Overstreet <kent.overstreet@linux.dev>

Previously, string_get_size() outputted a space between the number and
the units, i.e.
  9.88 MiB

This changes it to
  9.88MiB

which allows it to be parsed correctly by the 'sort -h' command.

This patch adds lib/lazy-percpu-counter.c, which implements counters
that start out as atomics, but lazily switch to percpu mode if the
update rate crosses some threshold (arbitrarily set at 256 per second).

+ * Lazy percpu counters:
+ * (C) 2022 Kent Overstreet
+ *
+ * Lazy percpu counters start out in atomic mode, then switch to percpu mode if
+ * the update rate crosses some threshold.
+ *
+ * This means we don't have to decide between low memory overhead atomic
+ * counters and higher performance percpu counters - we can have our cake and
+ * eat it, too!
+ *
+ * Internally we use an atomic64_t, where the low bit indicates whether we're in
+ * percpu mode, and the high 8 bits are a secondary counter that's incremented
+ * when the counter is modified - meaning 55 bits of precision are available for
+ * the counter itself.
+ *
+ * lazy_percpu_counter is 16 bytes (on 64 bit machines), raw_lazy_percpu_counter
+ * is 8 bytes but requires a separate unsigned long to record when the counter
+ * wraps - because sometimes multiple counters are used together and can share
+ * the same timestamp.

===========================
Code tagging framework
===========================
Code tag is a structure identifying a specific location in the source code
which is generated at compile time and can be embedded in an application-
specific structure. Several applications of code tagging are included in
this RFC, such as memory allocation tracking, dynamic fault injection,
latency tracking and improved error code reporting.
Basically, it takes the old trick of "define a special elf section for
objects of a given type so that we can iterate over them at runtime" and
creates a proper library for it.

===========================
Memory allocation tracking
===========================
The goal for using codetags for memory allocation tracking is to minimize
performance and memory overhead. By recording only the call count and
allocation size, the required operations are kept at the minimum while
collecting statistics for every allocation in the codebase. With that
information, if users are interested in mode detailed context for a
specific allocation, they can enable more in-depth context tracking,
which includes capturing the pid, tgid, task name, allocation size,
timestamp and call stack for every allocation at the specified code
location.
Memory allocation tracking is implemented in two parts:

part1: instruments page and slab allocators to record call count and total
memory allocated at every allocation in the source code. Every time an
allocation is performed by an instrumented allocator, the codetag at that
location increments its call and size counters. Every time the memory is
freed these counters are decremented. To decrement the counters upon free,
allocated object needs a reference to its codetag. Page allocators use
page_ext to record this reference while slab allocators use memcg_data of
the slab page.
The data is exposed to the user space via a read-only debugfs file called
alloc_tags.

Usage example:

$ sort -hr /sys/kernel/debug/alloc_tags|head
  153MiB     8599 mm/slub.c:1826 module:slub func:alloc_slab_page
 6.08MiB      49 mm/slab_common.c:950 module:slab_common func:_kmalloc_order
 5.09MiB     6335 mm/memcontrol.c:2814 module:memcontrol func:alloc_slab_obj_exts
 4.54MiB      78 mm/page_alloc.c:5777 module:page_alloc func:alloc_pages_exact
 1.32MiB      338 include/asm-generic/pgalloc.h:63 module:pgtable func:__pte_alloc_one
 1.16MiB      603 fs/xfs/xfs_log_priv.h:700 module:xfs func:xlog_kvmalloc
 1.00MiB      256 mm/swap_cgroup.c:48 module:swap_cgroup func:swap_cgroup_prepare
  734KiB     5380 fs/xfs/kmem.c:20 module:xfs func:kmem_alloc
  640KiB      160 kernel/rcu/tree.c:3184 module:tree func:fill_page_cache_func
  640KiB      160 drivers/char/virtio_console.c:452 module:virtio_console func:alloc_buf

part2: adds support for the user to select a specific code location to capture
allocation context. A new debugfs file called alloc_tags.ctx is used to select
which code location should capture allocation context and to read captured
context information.

Usage example:

$ cd /sys/kernel/debug/
$ echo "file include/asm-generic/pgalloc.h line 63 enable" > alloc_tags.ctx
$ cat alloc_tags.ctx
  920KiB      230 include/asm-generic/pgalloc.h:63 module:pgtable func:__pte_alloc_one
    size: 4096
    pid: 1474
    tgid: 1474
    comm: bash
    ts: 175332940994
    call stack:
         pte_alloc_one+0xfe/0x130
         __pte_alloc+0x22/0xb0
         copy_page_range+0x842/0x1640
         dup_mm+0x42d/0x580
         copy_process+0xfb1/0x1ac0
         kernel_clone+0x92/0x3e0
         __do_sys_clone+0x66/0x90
         do_syscall_64+0x38/0x90
         entry_SYSCALL_64_after_hwframe+0x63/0xcd
...

NOTE: slab allocation tracking is not yet stable and has a leak that
shows up in long-running tests. We are working on fixing it and posting
the RFC early to collect some feedback and to have a reference code in
public before presenting the idea at LPC2022.

===========================
Dynamic fault injection
===========================
Dynamic fault injection lets you do fault injection with a single call
to dynamic_fault(), with a debugfs interface similar to dynamic_debug.

Calls to dynamic_fault are listed in debugfs and can be enabled at
runtime (oneshot mode or a defined frequency are also available). This
patch also uses the memory allocation wrapper macros introduced by the
memory allocation tracking patches to add distinct fault injection
points for every memory allocation in the kernel.

Example fault injection points, after hooking memory allocation paths:

  fs/xfs/libxfs/xfs_iext_tree.c:606 module:xfs func:xfs_iext_realloc_rootclass:memory disabled "
  fs/xfs/libxfs/xfs_inode_fork.c:503 module:xfs func:xfs_idata_reallocclass:memory disabled "
  fs/xfs/libxfs/xfs_inode_fork.c:399 module:xfs func:xfs_iroot_reallocclass:memory disabled "
  fs/xfs/xfs_buf.c:373 module:xfs func:xfs_buf_alloc_pagesclass:memory disabled "
  fs/xfs/xfs_iops.c:497 module:xfs func:xfs_vn_get_linkclass:memory disabled "
  fs/xfs/xfs_mount.c:85 module:xfs func:xfs_uuid_mountclass:memory disabled "

===========================
Latency tracking
===========================
This lets you instrument code for measuring latency with just two calls
to code_tag_time_stats_start() and code_tag_time_stats_finish(), and
makes statistics available in debugfs on a per-callsite basis.

Recorded statistics include total count, frequency/rate, average
duration, max duration, and event duration quantiles.

Additionally, this patch instruments prepare_to_wait() and finish_wait().

Example output:

  fs/xfs/xfs_extent_busy.c:589 module:xfs func:xfs_extent_busy_flush
  count:          61
  rate:           0/sec
  frequency:    19 sec
  avg duration:   632 us
  max duration:   2 ms
  quantiles (us): 274 288 288 296 296 296 296 336 336 336 336 336 336 336 336

===========================
Improved error codes
===========================
Ever waste hours trying to figure out which line of code from some
obscure module is returning you -EINVAL and nothing else?

What if we had... more error codes?

This patch adds ERR(), which returns a unique error code that is related
to the error code that passed to it: the original error code can be
recovered with error_class(), and errname() (as well as %pE) returns an
error string that includes the file and line number of the ERR() call.

Example output:

  VFS: Cannot open root device "sda" or unknown-block(8,0): error -EINVAL at fs/ext4/super.c:4387

===========================
Dynamic debug conversion to code tagging
===========================
There are several open coded implementations of the "define a special elf
section for objects and iterate" technique that should be converted to
code tagging. This series just converts dynamic debug; there are others
(multiple in ftrace, in particular) that should also be converted.

===========================

The patchset applies cleanly over Linux 6.0-rc3
The tree for testing is published at:
https://github.com/surenbaghdasaryan/linux/tree/alloc_tags_rfc

The structure of the patchset is:
- code tagging framework (patches 1-6)
- page allocation tracking (patches 7-10)
- slab allocation tracking (patch 11-16)
- allocation context capture (patch 17-21)
- dynamic fault injection (patch 22)
- latency tracking (patch 23-27)
- improved error codes (patch 28)
- dynamic debug conversion to code tagging (patch 29)
- MAINTAINERS update (patch 30)

Next steps:
- track and fix slab allocator leak mentioned earlier;
- instrument more allocators: vmalloc, per-cpu allocations, others?

After redefining alloc_pages, all uses of that name are being replaced.
Change the conflicting names to prevent preprocessor from replacing them
when it's not intended.

Currently slab pages can store only vectors of obj_cgroup pointers in
page->memcg_data. Introduce slabobj_ext structure to allow more data
to be stored for each slab object. Wraps obj_cgroup into slabobj_ext
to support current functionality while allowing to extend slabobj_ext
in the future.

Note: ideally the config dependency should be turned the other way around:
MEMCG should depend on SLAB_OBJ_EXT and {page|slab|folio}.memcg_data would
be renamed to something like {page|slab|folio}.objext_data. However doing
this in RFC would introduce considerable churn unrelated to the overall
idea, so avoiding this until v1.

Slab extension objects can't be allocated before slab infrastructure is
initialized. Some caches, like kmem_cache and kmem_cache_node, are created
before slab infrastructure is initialized. Objects from these caches can't
have extension objects. Introduce SLAB_NO_OBJ_EXT slab flag to mark these
caches and avoid creating extensions for objects allocated from these
slabs.

This adds a new helper which is like strsep, except that it skips empty
tokens.

Implement mechanisms for capturing allocation call context which consists
of:
- allocation size
- pid, tgid and name of the allocating task
- allocation timestamp
- allocation call stack
The patch creates alloc_tags.ctx file which can be written to
enable/disable context capture for a specific code tag. Captured context
can be obtained by reading alloc_tags.ctx file.
Usage example:

echo "file include/asm-generic/pgalloc.h line 63 enable" > \
    /sys/kernel/debug/alloc_tags.ctx
cat alloc_tags.ctx
 91.0MiB      212 include/asm-generic/pgalloc.h:63 module:pgtable func:__pte_alloc_one
    size: 4096
    pid: 1551
    tgid: 1551
    comm: cat
    ts: 670109646361

From: Kent Overstreet <kent.overstreet@linux.dev>

This adds a new fault injection capability, based on code tagging.

To use, simply insert somewhere in your code

  dynamic_fault("fault_class_name")

and check whether it returns true - if so, inject the error.
For example

  if (dynamic_fault("init"))
      return -EINVAL;

There's no need to define faults elsewhere, as with
include/linux/fault-injection.h. Faults show up in debugfs, under
/sys/kernel/debug/dynamic_faults, and can be selected based on
file/module/function/line number/class, and enabled permanently, or in
oneshot mode, or with a specified frequency.

From: Kent Overstreet <kent.overstreet@linux.dev>

This patch converts bcache to the new generic time_stats code
lib/time_stats.c. The new code is from bcachefs, and has some changes
from the version in bcache:

 - we now use ktime_get_ns(), not local_clock(). When the code was
   originally written multi processor systems that lacked synchronized
   TSCs were still common, and so local_clock() was much cheaper than
   sched_clock() (though not necessarily fully accurate, due to TSC
   drift). ktime_get_ns() should be cheap enough on all common hardware
   now, and more standard/correct.

 - time_stats are now exported in a single file in sysfs, which means we
   can improve the statistics we keep track of without changing all
   users. This also means we don't have to manually specify which units
   (ms, us, ns) a given time_stats should be printed in; that's handled
   dynamically.

 - There's a lazily-allocated percpu buffer, which now needs to be freed

From: Kent Overstreet <kent.overstreet@linux.dev>

This adds a small new library for tracking statistics on events that
have a duration, i.e. a start and end time.

 - number of events
 - rate/frequency
 - average duration
 - max duration
 - duration quantiles

This code comes from bcachefs, and originally bcache: the next patch
will be converting bcache to use this version, and a subsequent patch
will be using code_tagging to instrument all wait_event() calls in the
kernel.

From: Kent Overstreet <kent.overstreet@linux.dev>

Cleanup for code tagging latency tracking:

Add an initializer, WAIT_FUNC_INITIALIZER(), to be used by initializers
for structs that include wait_queue_entries.

Also, change init_wait(), init_wait_entry etc.  to be a wrapper around
the new __init_waitqueue_entry(); more de-duplication prep work.

From: Kent Overstreet <kent.overstreet@linux.dev>

This converts dynamic debug to the new code tagging framework, which
provides an interface for iterating over objects in a particular elf
section.

It also converts the debugfs interface from seq_file to the style used
by other code tagging users, which also makes the code a bit smaller and
simpler.

It doesn't yet convert struct _ddebug to use struct codetag; another
cleanup could convert it to that, and to codetag_query_parse().

Add support for code tag context capture when registering a new code tag
type. When context capture for a specific code tag is enabled,
codetag_ref will point to a codetag_ctx object which can be attached
to an application-specific object storing code invocation context.
codetag_ctx has a pointer to its codetag_with_ctx object with embedded
codetag object in it. All context objects of the same code tag are placed
into codetag_with_ctx.ctx_head linked list. codetag.flag is used to
indicate when a context capture for the associated code tag is
initialized and enabled.

From: Kent Overstreet <kent.overstreet@linux.dev>

This patch adds per-error-site error codes, with error strings that
include their file and line number.

To use, change code that returns an error, e.g.
    return -ENOMEM;
to
    return -ERR(ENOMEM);

Then, errname() will return a string that includes the file and line
number of the ERR() call, for example
    printk("Got error %s!\n", errname(err));
will result in
    Got error ENOMEM at foo.c:1234

To convert back to the original error code (before returning it to
outside code that does not understand dynamic error codes), use
    return error_class(err);

To test if an error is of some type, replace
    if (err == -ENOMEM)
with
    if (error_matches(err, ENOMEM))

Implementation notes:

Error codes are allocated dynamically on module load and deallocated on
module unload. On memory allocation failure (i.e. the data structures
for indexing error strings and error parents), ERR() will fall back to
returning the error code that it was passed.

MAX_ERRNO has been raised from 4096 to 1 million, which should be
sufficient given the number of lines of code and the fraction that throw
errors in the kernel codebase.

This has implications for ERR_PTR(), since the range of the address
space reserved for errors is unavailable for other purposes. Since
ERR_PTR() ptrs are at the top of the address space there should not be
any major difficulties.

From: Kent Overstreet <kent.overstreet@linux.dev>

This adds the ability to easily instrument code for measuring latency.
To use, add the following to calls to your code, at the start and end of
the event you wish to measure:

  code_tag_time_stats_start(start_time);
  code_tag_time_stats_finish(start_time);

Stastistics will then show up in debugfs under
/sys/kernel/debug/time_stats, listed by file and line number.

Stastics measured include weighted averages of frequency, duration, max
duration, as well as quantiles.

This patch also instruments all calls to init_wait and finish_wait,
which includes all calls to wait_event. Example debugfs output:

Why not use percpu_counter? It has a per-cpu counter that is synchronised
when a batch threshold (default 32) is exceeded and can explicitly sync
the counters when required assuming the synchronised count is only needed
when reading debugfs.

Instead of renaming alloc_pages, why is the tagging not done in
__alloc_pages()? At least __alloc_pages_bulk() is also missed. The branch
can be guarded with IS_ENABLED.

Similar, the tagging could happen in a core function instead of a wrapper.

It's a valid question. From the description, it main addition that would
be hard to do with ftrace or probes is catching where an error code is
returned. A secondary addition would be catching all historical state and
not just state since the tracing started.

It's also unclear *who* would enable this. It looks like it would mostly
have value during the development stage of an embedded platform to track
kernel memory usage on a per-application basis in an environment where it
may be difficult to setup tracing and tracking. Would it ever be enabled
in production? Would a distribution ever enable this? If it's enabled, any
overhead cannot be disabled/enabled at run or boot time so anyone enabling
this would carry the cost without never necessarily consuming the data.

It might be an ease-of-use thing. Gathering the information from traces
is tricky and would need combining multiple different elements and that
is development effort but not impossible.

Whatever asking for an explanation as to why equivalent functionality
cannot not be created from ftrace/kprobe/eBPF/whatever is reasonable.

Hi Suren,

If this is going to be used by mainline kernel, it would be good to
integrate this with fail_nth systematic fault injection:
https://elixir.bootlin.com/linux/latest/source/lib/fault-inject.c#L109

Otherwise these dynamic sites won't be tested by testing systems doing
systematic fault injection testing.

There are number of cases where pcidevs_lock() is used to protect
something that is not related to PCI devices per se.

Probably pcidev_lock in these places should be replaced with some
other lock.

This patch is not intended to be merged and is present only to discuss
this use of pcidevs_lock()

ATS subsystem has own list of PCI devices. As we are going to remove
global pcidevs_lock() in favor to more granular locking, we need to
ensure that this list is protected somehow. To do this, we need to add
additional lock for each IOMMU, as list to be protected is also part
of IOMMU.

Hello,

This is yet another take to a PCI locking rework. This approach
was suggest by Jan Beulich who proposed to use a reference
counter to control lifetime of pci_dev objects.

When I started added reference counting it quickly became clear
that this approach can provide more granular locking insted of
huge pcidevs_lock() which is used right now. I studied how this
lock used and what it protects. And found the following:

0. Comment in pci.h states the following:

 153 /*
 154  * The pcidevs_lock protect alldevs_list, and the assignment for the
 155  * devices, it also sync the access to the msi capability that is not
 156  * interrupt handling related (the mask bit register).
 157  */

But in reality it does much more. Here is what I found:

1. Lifetime of pci_dev struct

2. Access to pseg->alldevs_list

3. Access to domain->pdev_list

4. Access to iommu->ats_list

5. Access to MSI capability

6. Some obsucure stuff in IOMMU drivers: there are places that
are guarded by pcidevs_lock() but it seems that nothing
PCI-related happens there.

7. Something that I probably overlooked

Anyways, I tried to get rid of global mighty pcidevs_lock() by
reworking items 1-5.

This patch series does exactly this: adds separate lock for each
of the lists, lock for struct pci_dev itself, adds reference
counting, then removes pcidevs_lock() entirely. I do understand
that I should not remove locks when there are locking fixes for
items 6-7. But this is why it is an RFC. I want to discuss if my
approach is legit and get some guidance from maintainers on what
should be done in addition to the presented changes.

This lock protects alldevs_list of struct pci_seg. As this, it should
be used when we are adding, removing on enumerating PCI devices
assigned to a PCI segment.

Radix tree that stores PCI segment has own locking mechanism, also
pci_seg structures are only allocated and newer freed, so we need no
additional locking to access pci_seg structures. But we need a lock
that protects alldevs_list field.

This enables more granular locking instead of one huge pcidevs_lock
that locks entire PCI subsystem.  Please note that pcidevs_lock() is
still used, we are going to remove it in subsequent patches.

We can use reference counter to ease up object lifetime management.
This patch adds very basic support for reference counters. refcnt
should be used in the following way:

1. Protected structure should have refcnt_t field

2. This field should be initialized with refcnt_init() during object
construction.

3. If code holds a valid pointer to a structure/object it can increase
refcount with refcnt_get(). No additional locking is required.

4. Code should call refcnt_put() before dropping pointer to a
protected structure. `destructor` is a call back function that should
destruct object and free all resources, including structure protected
itself. Destructor will be called if reference counter reaches zero.

5. If code does not hold a valid pointer to a protected structure it
should use other locking mechanism to obtain a pointer. For example,
it should lock a list that hold protected objects.

domain->pdevs_lock protects access to domain->pdev_list.
As this, it should be used when we are adding, removing on enumerating
PCI devices assigned to a domain.

This enables more granular locking instead of one huge pcidevs_lock that
locks entire PCI subsystem. Please note that pcidevs_lock() is still
used, we are going to remove it in subsequent patches.

Prior to this change, lifetime of pci_dev objects was protected by global
pcidevs_lock(). We are going to get if of this lock, so we need some
other mechanism to ensure that those objects will not disappear under
feet of code that access them. Reference counting is a good choice as
it provides easy to comprehend way to control object lifetime with
better granularity than global super lock.

This patch adds two new helper functions: pcidev_get() and
pcidev_put(). pcidev_get() will increase reference counter, while
pcidev_put() will decrease it, destroying object when counter reaches
zero.

pcidev_get() should be used only when you already have a valid pointer
to the object or you are holding lock that protects one of the
lists (domain, pseg or ats) that store pci_dev structs.

pcidev_get() is rarely used directly, because there already are
functions that will provide valid pointer to pci_dev struct:
pci_get_pdev() and pci_get_real_pdev(). They will lock appropriate
list, find needed object and increase its reference counter before
returning to the caller.

Naturally, pci_put() should be called after finishing working with a
received object. This is the reason why this patch have so many
pcidev_put()s and so little pcidev_get()s: existing calls to
pci_get_*() functions now will increase reference counter
automatically, we just need to decrease it back when we finished.

This patch removes "const" qualifier from some pdev pointers because
pcidev_put() technically alters the contents of pci_dev structure.

Hey all,

The design session website is up:

https://design-sessions.xenproject.org

If you=E2=80=99re attending the event in Cambridge, please register an =
account and submit your topics for discussion.

As a reminder, here=E2=80=99s how we tried to balance ease-of-use with =
fighting spam:

During =E2=80=9Cphase 1=E2=80=9D, anyone can create an account; but =
accounts by default start as =E2=80=9Cunverified=E2=80=9D.

Unverified accounts can create design sessions, but those sessions are =
not visible until approved by the admin.  Unverified accounts can also =
modify their own sessions=E2=80=99 titles and descriptions, but those =
changes aren=E2=80=99t visible until approved by the admin.

The admin can manually verify any account that looks like it=E2=80=99s =
valid.  Verified accounts=E2=80=99 design sessions are visible =
immediately.

At some point, we send out a verification code to all attendees; usually =
a week before the conference.  This starts phase 2, where anyone can =
still create an account; but attendees can verify *themselves* by =
putting in the verification code.

Once the conference starts, we move on to phase 3, where you must have a =
verification code to create an account.  (And naturally your account =
starts in the =E2=80=98verified=E2=80=99 state.)

See you at the Summit!

 -George

Thank you for the question.
For memory tracking my intent is to have a mechanism that can be enabled in
the field testing (pre-production testing on a large population of
internal users).
The issue that we are often facing is when some memory leaks are happening
in the field but very hard to reproduce locally. We get a bugreport
from the user
which indicates it but often has not enough information to track it. Note that
quite often these leaks/issues happen in the drivers, so even simply finding out
where they came from is a big help.
The way I envision this mechanism to be used is to enable the basic memory
tracking in the field tests and have a user space process collecting
the allocation
statistics periodically (say once an hour). Once it detects some counter growing
infinitely or atypically (the definition of this is left to the user
space) it can enable
context capturing only for that specific location, still keeping the
overhead to the
minimum but getting more information about potential issues. Collected stats and
contexts are then attached to the bugreport and we get more visibility
into the issue
when we receive it.
The goal is to provide a mechanism with low enough overhead that it
can be enabled
all the time during these field tests without affecting the device's
performance profiles.
Tracing is very cheap when it's disabled but having it enabled all the
time would
introduce higher overhead than the counter manipulations.
My apologies, I should have clarified all this in this cover letter
from the beginning.

As for other applications, maybe I'm not such an advanced user of
tracing but I think only
the latency tracking application might be done with tracing, assuming
we have all the
right tracepoints but I don't see how we would use tracing for fault
injections and
descriptive error codes. Again, I might be mistaken.

Thanks,
Suren.

The intent is to use atomic counters for places that are not updated very often.
This would save memory required for the counters. Originally I had a config
option to choose which counter type to use but with lazy counters we sacrifice
memory for performance only when needed while keeping the other counters
small.

Hmm. Assuming all the other allocators using __alloc_pages are inlined, that
should work. I'll try that and if that works will incorporate in the
next respin.
Thanks!

I don't think IS_ENABLED is required because the tagging functions are already

Same question as before. Why not just use feature_persistent directly?

Aside: IMO this would look nicer as below:

	info->feature_persistent = feature_persistent && !!xenbus_read_unsigned();

If feature_gnt_persistent_parm is always going to be equal to 
feature_persistent, then why introduce it at all? Why not just use 
feature_persistent directly? This way you avoid adding an extra flag 
whose purpose is not immediately clear, and you also avoid all the mess 
with setting this flag at the right time.

Catching all historical state is pretty important in the case of memory
allocation accounting, don't you think?

Also, ftrace can drop events. Not really ideal if under system load your memory
accounting numbers start to drift.

The whole point of this is to be cheap enough to enable in production -
especially the latency tracing infrastructure. There's a lot of value to
always-on system visibility infrastructure, so that when a live machine starts
to do something wonky the data is already there.

What we've built here this is _far_ cheaper than anything that could be done
with ftrace.

I think perhaps some of the expectation should be on the "ftrace for
everything!" people to explain a: how their alternative could be even built and
b: how it would compare in terms of performance and ease of use.

Look, I've been a tracing user for many years, and it has its uses, but some of
the claims I've been hearing from tracing/bpf people when any alternative
tooling is proposed sound like vaporware and bullshitting.

Mainly because the parameter should read twice (once for advertisement, and
once later just before the negotitation, for checking if we advertised or not),
and the user might change the parameter value between the two reads.

For the detailed available sequence of the race, you could refer to the prior
conversation[1].

It doesn't switch from atomic mode to percpu mode when the update rate crosses a
threshold like lazy percpu counters does, it allocates all the percpu counters
up front - that makes it a non starter here.

Also, from my reading of the code... wtf is it even doing, and why would I use
it at all? This looks like old grotty code from ext3, it's not even using
this_cpu_add() - it does preempt_enable()/disable() just for adding to a local
percpu counter!

Noooooope.

Same answer as before, due to the possible race[1].

Subject: [PATCH v2 0/3] xen-blk{front,back}: Fix the broken semantic and flow of feature-persistent

Message-Id: <20220831165824.94815-1-sj@kernel.org>

Changes from v1
(https://lore.kernel.org/xen-devel/20220825161511.94922-1-sj@kernel.org/)
- Fix the wrong feature_persistent caching position of blkfront
- Set blkfront's feature_persistent field setting with simple '&&'
  instead of 'if' (Pratyush Yadav)

This patchset fixes misuse of the 'feature-persistent' advertisement
semantic (patches 1 and 2), and the wrong timing of the
'feature_persistent' value caching, which made persistent grants feature
always disabled.

SeongJae Park (3):
  xen-blkback: Advertise feature-persistent as user requested
  xen-blkfront: Advertise feature-persistent as user requested
  xen-blkfront: Cache feature_persistent value before advertisement

The advertisement of the persistent grants feature (writing
'feature-persistent' to xenbus) should mean not the decision for using
the feature but only the availability of the feature.  However, commit
aac8a70db24b ("xen-blkback: add a parameter for disabling of persistent
grants") made a field of blkback, which was a place for saving only the
negotiation result, to be used for yet another purpose: caching of the
'feature_persistent' parameter value.  As a result, the advertisement,
which should follow only the parameter value, becomes inconsistent.

This commit fixes the misuse of the semantic by making blkback saves the
parameter value in a separate place and advertises the support based on
only the saved value.

Fixes: aac8a70db24b ("xen-blkback: add a parameter for disabling of persistent grants")

Subject: [PATCH v2 2/3] xen-blkfront: Advertise feature-persistent as user requested

The advertisement of the persistent grants feature (writing
'feature-persistent' to xenbus) should mean not the decision for using
the feature but only the availability of the feature.  However, commit
74a852479c68 ("xen-blkfront: add a parameter for disabling of persistent
grants") made a field of blkfront, which was a place for saving only the
negotiation result, to be used for yet another purpose: caching of the
'feature_persistent' parameter value.  As a result, the advertisement,
which should follow only the parameter value, becomes inconsistent.

This commit fixes the misuse of the semantic by making blkfront saves
the parameter value in a separate place and advertises the support based
on only the saved value.

Subject: [PATCH v2 3/3] xen-blkfront: Cache feature_persistent value before advertisement

Xen blkfront advertises its support of the persistent grants feature
when it first setting up and when resuming in 'talk_to_blkback()'.
Then, blkback reads the advertised value when it connects with blkfront
and decides if it will use the persistent grants feature or not, and
advertises its decision to blkfront.  Blkfront reads the blkback's
decision and it also makes the decision for the use of the feature.

Commit 402c43ea6b34 ("xen-blkfront: Apply 'feature_persistent' parameter
when connect"), however, made the blkfront's read of the parameter for
disabling the advertisement, namely 'feature_persistent', to be done
when it negotiate, not when advertise.  Therefore blkfront advertises
without reading the parameter.  As the field for caching the parameter
value is zero-initialized, it always advertises as the feature is
disabled, so that the persistent grants feature becomes always disabled.

This commit fixes the issue by making the blkfront does parmeter caching
just before the advertisement.

Please note that I have some problem in my test setup and therefore was unable
to fully test this patchset.  I am posting this though, as the impact of the
bug is not trivial (always disabling persistent grants), and to make testing of
my proposed fix from others easier.  Hope to get someone's test results or code
review of this patchset even before I fix my test setup problem.

Juergen, I didn't add your 'Reviewed-by:'s to the first two patches of this
series because I changed some of the description for making it clear which bug
and commit it is really fixing.  Specifically, I wordsmithed the working and
changed 'Fixed:' tag.  Code change is almost same, though.


Thanks,
SJ

That's a discussion we need to have, yeah. We don't want two distinct fault
injection frameworks, we'll have to have a discussion as to whether this is (or
can be) better enough to make a switch worthwhile, and whether a compatibility
interface is needed - or maybe there's enough distinct interesting bits in both
to make merging plausible?

The debugfs interface for this fault injection code is necessarily different
from our existing fault injection - this gives you a fault injection point _per
callsite_, which is huge - e.g. for filesystem testing what I need is to be able
to enable fault injection points within a given module. I can do that easily
with this, not with our current fault injection.

I think the per-callsite fault injection points would also be pretty valuable
for CONFIG_FAULT_INJECTION_USERCOPY, too.

OTOH, existing kernel fault injection can filter based on task - this fault
injection framework doesn't have that. Easy enough to add, though. Similar for
the interval/probability/ratelimit stuff.

fail_function is the odd one out, I'm not sure how that would fit into this
model. Everything else I've seen I think fits into this model.

Also, it sounds like you're more familiar with our existing fault injection than
I am, so if I've misunderstood anything about what it can do please do correct
me.

Interestingly: I just discovered from reading the code that
CONFIG_FAULT_INJECTION_STACKTRACE_FILTER is a thing (hadn't before because it
depends on !X86_64 - what?). That's cool, though.

It can't be in a function, it has to be in a wrapper macro.

alloc_tag_add() is a macro that defines a static struct in a special elf
section. That struct holds the allocation counters, and putting it in a special
elf section is how the code to list it in debugfs finds it.

Look at the dynamic debug code for prior precedence for this trick in the kernel
- that's how it makes pr_debug() calls dynamically controllable at runtime, from
debugfs. We're taking that method and turning it into a proper library.

Because all the counters are statically allocated, without even a pointer deref
to get to them in the allocation path (one pointer deref to get to them in the
deallocate path), that makes this _much, much_ cheaper than anything that could
be done with tracing - cheap enough that I expect many users will want to enable
it in production.

In the case of memory allocation accounting, you flat cannot do this with ftrace
- you could maybe do a janky version that isn't fully accurate, much slower,
more complicated for the developer to understand and debug and more complicated
for the end user.

But please, I invite anyone who's actually been doing this with ftrace to
demonstrate otherwise.

Ftrace just isn't the right tool for the job here - we're talking about adding
per callsite accounting to some of the fastest fast paths in the kernel.

And the size of the changes for memory allocation accounting are much more
reasonable:
 33 files changed, 623 insertions(+), 99 deletions(-)

The code tagging library should exist anyways, it's been open coded half a dozen
times in the kernel already.

And once we've got that, the time stats code is _also_ far simpler than doing it
with ftrace would be. If anyone here has successfully debugged latency issues
with ftrace, I'd really like to hear it. Again, for debugging latency issues you
want something that can always be on, and that's not cheap with ftrace - and
never mind the hassle of correlating start and end wait trace events, builting
up histograms, etc. - that's all handled here.

Cheap, simple, easy to use. What more could you want?

Below the new commit message:

     Unlike arm64, on arm32 there are no extra information dumped (e.g.
     page table walk) for hypervisor data abort.

     For data abort, the HSR will be set properly and so call
     do_trap_hyp_sync() instead of do_unexpected_trap() on arm32 to have
     the print the same information as arm64.

The link also contains a pointer to a patch which is...

... not included in 5.15.19 but is at least included in the latest
stable version for 5.15 (5.15.63).

Please update the latest v5.15.X and check if this issue is still present.

The error message is a sign something went horribly wrong. The right 
solution is to find the root cause rather than...

... decreasing the verbosity.

Hi Julien,

I do not think this patch actually affects this behaviour.
But I will check.

The link also contains a pointer to a patch which is...<br>
<br>
&gt; <br>
&gt; DOM0/DOMU kernels version 5.15.19<br>
<br>
... not included in 5.15.19 but is at least included in the latest<br>
stable version for 5.15 (5.15.63).<br>
<br>
Please update the latest v5.15.X and check if this issue is still present.<=
br>
<br>
[...]<br>
<br>
&gt; It is produced unconditionally. In =C2=A0the above mentioned condition=
 this <br>
&gt; output<br>
&gt; degrades the performance drastically.<br>
<br>
The error message is a sign something went horribly wrong. The right <br>
solution is to find the root cause rather than...<br>
<br>
&gt; I may offer a patch which decreases the amount of messages.<br>
<br>
... decreasing the verbosity.<br>

Patches 1, 4, and 6 are already committed. I plan to commit patches 2, 3
and 5 in the next couple of days.

Patch 7 needs further discussions and it is best addressed during the
next MISRA C sync-up.

I looked at the series and patches 1-5 are ready to be committed.

Patch 6 needs an Ack, preferably from Jan as Jan had questions on this
patch in v9.

I plan to commit patches 1-5 in the next couple of days (and ideally
patch 6 too if an Ack comes from Jan).

Cheers,

Stefano

I see. I didn't realize the full implications of the memory being used
for both xenheap and domheap on arm32. In that case, I would simply do
the following:


    heap_pages = !reserved_heap ? ram_pages : reserved_heap_pages;

    if ( opt_xenheap_megabytes )
        xenheap_pages = opt_xenheap_megabytes << (20-PAGE_SHIFT);
    else
    {
        xenheap_pages = (heap_pages/32 + 0x1fffUL) & ~0x1fffUL;
        xenheap_pages = max(xenheap_pages, 32UL<<(20-PAGE_SHIFT));
        xenheap_pages = min(xenheap_pages, 1UL<<(30-PAGE_SHIFT));
    }

    if ( reserved_heap )
        e = reserved_heap_end;
    else
    {
        do
        {
            e = consider_modules(ram_start, ram_end,
                                 pfn_to_paddr(xenheap_pages),
                                 32<<20, 0);

            if ( e )
                break;

            xenheap_pages >>= 1;
        } while ( !opt_xenheap_megabytes && xenheap_pages > 32<<(20-PAGE_SHIFT) );
    }

    if ( ! e ||
         ( reserved_heap && reserved_heap_pages < 32<<(20-PAGE_SHIFT) ) )
        panic("Not enough space for xenheap\n");

    domheap_pages = heap_pages - xenheap_pages;
