Try
and
get native WinXP to boot
and initialise both cards at the same time .. acid test .. you`ll know
if you
are wasting your time or not !
Hi Tim,
I am aware that Magee told me that onboard GMA4500 and PCI-e x16
graphics
cannot work simultaneously.
But Weidong told me in earlier postings that he could get secondary gfx
to work
in the labs, so I am still holding out some hope of getting my
secondary gfx to
be passed through to windows xp hvm domU.

hi
Teo,
I
believe
it is due to your
motherboard - In a previous post to xen-devel, as user said to YOU that
the
chipset does not have enough PCI Lanes to use both Internal IGFX and
PCIe card at
the same time (simultaneously). Primary (IGFX) will need to be disabled
in your
BIOS for PCIe card to work, can you get them both enabled in native
WinXP?
If I
were
you, I would try and
pass through the Primary (IGFX) VGA controller to DomU with the
specific
changes needed to memory addresses in the v1 patches .. see if that
works.
Dont
think you will have much
luck with your secondary PCIe card - (I couldnt get PCIe secondary
working
either, and my secondary does work in native WinXP)

Hi Weidong,
Do you have any ideas why gfx passthrough couldn’t work
in my case?

Hi
Weidong,
Thank
you
for all your hard work
;)
I
have
just successfully passed
through my Nvidia Geforce GTX260 as a fully functional card to my WinXP
DomU
!!!!!
My
findings so far:
1)
Tried
with my 9500 GT
(Secondary card) which DOES load the driver successfully but NO output
on the Monitor
(VGA is sized correctly but monitor is OFF)
2)
GTX260
(Primary card) (Dom0
boot VGA) starting DomU from remote SSH console, VGA Loads and Display
works
!!!!
In
both
cases I am using the
NVidia binary driver in the WinXP DomU.
The
9500GT (Secondary card)
passthrough still has issues, the driver loads without the Monitor
displaying
anything (DPMS?) and if I make ANY changes to the DomU Graphics then
the DomU
locks up hard.
[Weidong]:
I
didn't try
9500GT. Seems it needs extra
hacks.
In
both
cases the VGA card only
works the FIRST time, I.e. FLR is required to reset the card for
re-use,
display become corrupt on second boot of DomU. Restart Dom0 and the VGA
will
work again the first time DomU is started.
[Weidong]: Yes,
it's
not
reset
well. I suspect it's still in graphics mode, so cannot display
the boot
messages in VGA mode. In my experiments, WinXP guest can still
boot into graphics mode, although you cannot see booting
progress.
Is
there
anyway we can
impletement the d3r, sbr or flr functionality that is in XCI? I would
like to
see if a sbr will enable to Card to be reset.
[Weidong]:
these
reset functions
are already in xen-unstable,
but no one can really reset gfx. In my feeling, it needs vendor
specific method to reset it.
I
would
also like to debug the
issue with Secondary passthrough as it seems that this is nearly there
too ...
Regards,
Tim
Dear Magee,
Any luck with the Intel vga passthrough patches to xen
3.5-unstable
on Intel DQ45CB with extra PCI-e x16 graphics card? Are you using pvops
dom 0
kernels 2.6.30-rc3 and 2.6.31-rc6?

That was the problem,
thank you. Now I’ll work on testing the gfx-passthrough patches.
I suspect you are using old hvm config file. The
device_model is
changes in config file.
in old config file:
# New stuff
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
in new config file:
# Device Model to be used
device_model = 'qemu-dm'
Pls check it, and use the latest config file to create
guest.
Regards,
Weidong

Subject: [Xen-devel] xen-unstable pci passthrough
I have not been able to
passthrough any PCI
devices using the latest xen-unstable. I have a DQ45CB, and have
successfully passed devices to guests using 3.4.1.
The latest c/s in my copy
of
xen-unstable
is 20145. I just started playing around with unstable yesterday, so I
can’t tell you if earlier revisions worked. I’ve tried with various
dom0
kernels, the current 2.6.18.8-xen branch, a xenified 2.6.29.6, and a
pvops
2.6.31-rc6, and in every case I get the same error. I’ve tried both
putting pci= in the config file, and hot-adding the device using xm
pci-attach. In every case, the xm command (either create or
pci-attach)
fails with the message “Error: Timed out waiting for device model
action”. The guests in every case are HVM guests, some flavors of
Windows, as well as the Knoppix 5.3.1 DVD.
The relevant xm dmesg
output
is:
(XEN) PCI add device 00:1b.0
(XEN)
[VT-D]iommu.c:1292:d0
domain_context_unmap:PCIe: bdf = 0:1b.0

And the messages from
qemu-log:
dm-command: hot insert
pass-through pci dev
hot add pci slot -2
exceed.
Please let me know what
else
I need to
supply to help resolve this problem. If I need to enable debugging
messages, let me know the best way to do this.
