Re: [Xen-devel] [Intel-gfx] [Announcement] 2016-Q3 release of XenGT - a Mediated Graphics Passthrough Solution from Intel



Hi all,

We are pleased to announce another update of Intel GVT-g for Xen.

Intel GVT-g is a full GPU virtualization solution with mediated pass-through, 
starting from 4th generation Intel Core(TM) processors with Intel Graphics 
processors. A virtual GPU instance is maintained for each VM, with part of 
performance critical resources directly assigned. The capability of running 
native graphics driver inside a VM, without hypervisor intervention in 
performance critical paths, achieves a good balance among performance, feature, 
and sharing capability. Xen is currently supported on Intel Processor Graphics 
(a.k.a. XenGT).


Repositories

-    Xen: https://github.com/01org/igvtg-xen (2016q3-4.6 branch)
-    Kernel: https://github.com/01org/igvtg-kernel (2016q3-4.3.0 branch)
-    Qemu: https://github.com/01org/igvtg-qemu (2016q3-2.3.0 branch)


This update consists of:

-    Preliminary support new platform: 7th generation Intel® Core™ processors. 
For windows OS, it only supports Win10 RedStone 64 bit.

-    Windows 10 RedStone guest Support

-    Windows Guest QoS preliminary support:  Administrators now are able to 
control the maximum amount of vGPU resource to be consumed by each VM from 
value 1% ~ 99%”

-    Display virtualization preliminary support: Besides the tracking of 
display register visit in guest VM, removing irrelative display pipeline info 
between host and guest VM

-    Live Migration and savevm/restorevm preliminary support on BDW with 2D/3D 
workload running



Known issues:

-   At least 2GB memory is suggested for Guest Virtual Machine (win7-32/64, 
win8.1-64, win10-64) to run most 3D workloads

-   Windows8 and later Windows fast boot is not supported, the workaround is to 
disable power S3/S4 in HVM file by adding “acpi_S3=0, acpi_S4=0”

-   Sometimes when dom0 and guest has heavy workload, i915 in dom0 will trigger 
a false-alarmed TDR. The workaround is to disable dom0 hangcheck in dom0 grub 
file by adding “i915.enable_hangcheck=0”

-   Stability: When QoS feature is enabled, Windows guest full GPU reset is 
often trigger during MTBF test.  This bug will be fixed in next release

-   Windows guest running OpenCL allocations occurs to host crash; the 
workaround is to disable logd in dom0 grub file by adding “i915. logd_enable =0”


Next update will be around early Jan, 2017.

Note: The XenGT project should be considered a work in progress. As such it is 
not a complete product nor should it be considered one. Extra care should be 
taken when testing and configuring a system to use the XenGT project.
