Commit: Anthony PERARD CommitDate: Thu Nov 16 15:40:08 2017 +0000 xen/pt: allow QEMU to request MSI unmasking at bind time When a MSI interrupt is bound to a guest using xc_domain_update_msi_irq (XEN_DOMCTL_bind_pt_irq) the interrupt is left masked by default. This causes problems with guests that first configure interrupts and clean the per-entry MSIX table mask bit and afterwards enable MSIX globally. In such scenario the Xen internal msixtbl handlers would not detect the unmasking of MSIX entries because vectors are not yet registered since MSIX is not enabled, and vectors would be left masked.

This causes problems with guests that first configure interrupts and clean the per-entry MSIX table mask bit and afterwards enable MSIX globally. In such scenario the Xen internal msixtbl handlers would not detect the unmasking of MSIX entries because vectors are not yet registered since MSIX is not enabled, and vectors would be left masked. Introduce a new flag in the gflags field to signal Xen whether a MSI interrupt should be unmasked after being bound. This also requires to track the mask register for MSI interrupts, so QEMU can also notify to Xen whether the MSI interrupt should be bound masked or unmasked Signed-off-by: Roger Pau Monné Reviewed-by: Jan Beulich Reported-by: Andreas Kinzler Reviewed-by: Stefano Stabellini Signed-off-by: Stefano Stabellini (cherry picked from commit a8036336609d2e184fc3543a4c439c0ba7d7f3a2) --- hw/xen/xen_pt.h | 1 + hw/xen/xen_pt_config_init.c | 20 ++++++++++++++++++-- hw/xen/xen_pt_msi.c | 13 ++++++++++--- 3 files changed, 29 insertions(+), 5 deletions(-) diff --git a/hw/xen/xen_pt.h b/hw/xen/xen_pt.h index 191d9ca..aa39a9a 100644 --- a/hw/xen/xen_pt.h +++ b/hw/xen/xen_pt.h @@ -180,6 +180,7 @@ typedef struct XenPTMSI { uint32_t addr_hi;

This causes problems with guests that first configure interrupts and clean the per-entry MSIX table mask bit and afterwards enable MSIX globally. In such scenario the Xen internal msixtbl handlers would not detect the unmasking of MSIX entries because vectors are not yet registered since MSIX is not enabled, and vectors would be left masked. Introduce a new flag in the gflags field to signal Xen whether a MSI interrupt should be unmasked after being bound. This also requires to track the mask register for MSI interrupts, so QEMU can also notify to Xen whether the MSI interrupt should be bound masked or unmasked Signed-off-by: Roger Pau Monné

26f9a18485b5daf5215c8032a3049821c374b148 Author: Brian Woods AuthorDate: Tue Oct 31 17:03:08 2017 -0500 Commit: Andrew Cooper CommitDate: Fri Dec 1 19:03:27 2017 +0000 x86/svm: add virtual VMLOAD/VMSAVE support On AMD family 17h server processors, there is a feature called virtual VMLOAD/VMSAVE. This allows a nested hypervisor to preform a VMLOAD or VMSAVE without needing to be intercepted by the host hypervisor. Virtual VMLOAD/VMSAVE requires the host hypervisor to be in long mode and nested page tables to be enabled. For more information about it please see: AMD64 Architecture Programmer’s Manual Volume 2: System Programming http://support.amd.com/TechDocs/24593.pdf Section: VMSAVE and VMLOAD Virtualization (Section 15.33.1) This patch series adds support to check for and enable the virtual VMLOAD/VMSAVE features if available.

Under different modes, it + shows different type of data. + + There are two modes: + Linear mode: the input precision is defined as 100-(MBA_MAX). For instance, + if the MBA_MAX value is 90, the input precision is 10%. Values not an even + multiple of the precision (e.g., 12%) will be rounded down (e.g., to 10% + delay applied) by HW automatically. The response of throttling value is + linear. + + Non-linear mode: input delay values are powers-of-two from zero to the + MBA_MAX value from CPUID. In this case any values not a power of two will + be rounded down the next nearest power of two by HW automatically. The + response of throttling value is non-linear. + + For linear mode, it shows the decimal value. For non-linear mode, it shows + hexadecimal value. + + 2. `psr-mba-set [OPTIONS] `: + + Set memory bandwidth throttling for domain. + + Options: + '-s': Specify the socket to process, otherwise all sockets are processed. + + Throttling value set in register implies the approximate amount of delaying + the traffic between core and memory. Higher throttling value result in + lower bandwidth. The max throttling value (MBA_MAX) supported can be + obtained through CPUID inside hypervisor. Users can fetch the MBA_MAX value + using the `psr-hwinfo` xl command. + +# Technical details + +MBA is a member of Intel PSR features, it shares the base PSR infrastructure +in Xen. + +## Hardware perspective + + MBA defines a range of MSRs to support specifying a delay value (Thrtl) per + COS, with details below. + + ``` + +----------------------------+----------------+ + | MSR (per socket) | Address | + +----------------------------+----------------+ + | IA32_L2_QOS_Ext_BW_Thrtl_0 | 0xD50 | + +----------------------------+----------------+ + | ... | ... | + +----------------------------+----------------+ + | IA32_L2_QOS_Ext_BW_Thrtl_n | 0xD50+n | + +----------------------------+----------------+ + ``` + + When context switch happens, the COS ID of domain is written to per-hyper- + thread MSR `IA32_PQR_ASSOC`, and then hardware enforces bandwidth allocation + according to the throttling value stored in the Thrtl MSR register. + +## The relationship between MBA and CAT/CDP + + Generally speaking, MBA is completely independent of CAT/CDP, and any + combination may be applied at any time, e.g. enabling MBA with CAT + disabled. + + But it needs to be noticed that MBA shares COS infrastructure with CAT, + although MBA is enumerated by different CPUID leaf from CAT (which + indicates that the max COS of MBA may be different from CAT). In some + cases, a domain is permitted to have a COS that is beyond one (or more) + of PSR features but within the others. For instance, let's assume the max + COS of MBA is 8 but the max COS of L3 CAT is 16, when a domain is assigned + 9 as COS, the L3 CAT CBM associated to COS 9 would be enforced, but for MBA, + the HW works as default value is set since COS 9 is beyond the max COS (8) + of MBA. + +## Design Overview + +* Core COS/Thrtl association + + When enforcing Memory Bandwidth Allocation, all cores of domains have + the same default Thrtl MSR (COS0) which stores the same Thrtl (0). The + default Thrtl MSR is used only in hypervisor and is transparent to tool stack + and user. + + System administrators can change PSR allocation policy at runtime by + using the tool stack. Since MBA shares COS ID with CAT/CDP, a COS ID + corresponds to a 2-tuple, like [CBM, Thrtl] with only-CAT enabled, when CDP + is enabled, the COS ID corresponds to a 3-tuple, like [Code_CBM, Data_CBM, + Thrtl]. If neither CAT nor CDP is enabled, things are easier, since one COS + ID corresponds to one Thrtl. + +* VCPU schedule + + This part reuses CAT COS infrastructure. + +* Multi-sockets + + Different sockets may have different MBA capabilities (like max COS) + although it is consistent on the same socket.

Change type of 'cat_init_feature' to 'bool' to remove the pointless returning of error code. 2. Move printk in 'cat_init_feature' to reduce a return path. 3. Define a local variable 'feat_mask' in 'psr_cpu_init' to reduce calling of 'cpuid_count_leaf()'. 4. Change 'PSR_INFO_IDX_CAT_FLAG' to 'PSR_INFO_IDX_CAT_FLAGS'.

Like CAT features, MBA HW info has cos_max which means the max thrtl register number, and thrtl_max which means the max throttle value (delay value). It also has a flag to represent if the throttle value is linear or non-linear. One thrtl register of MBA stores a throttle value for one or more domains. The throttle value means the delay applied to traffic between L2 cache and next cache level. This patch also implements init flow for MBA and register stub callback functions.
