Yes, if you find and problem on we mentioned platform, you can file a bug on 
fd. (https://bugs.freedesktop.org/)  with component "DRM/iGVT-g".

Does this mean that all SKUs from those platforms are supported so that when
users report bugs, they will be worked on?

[Intel-gfx] [GVT-g] [ANNOUNCE] 2018-Q3 release of KVMGT (Intel GVT-g for KVM)

[Xu, Terrence]

Hi all,



We are pleased to announce an update of Intel GVT-g for KVM.



Intel GVT-g for KVM (a.k.a. KVMGT) is a full GPU virtualization solution with 
mediated pass-through, starting from 5th generation Intel Core(TM) processors 
with Intel processor graphics.  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.





Repositories:

-Kernel: https://github.com/01org/gvt-linux  (tag: 2018-q3-gvt-stable-4.17)

-Qemu: https://github.com/01org/igvtg-qemu  (tag: 2018-q3-stable-2.12.0)



Platform Support:

-Server platforms: Intel(r) Xeon(r) E3_v4, E3_v5 and E3_v6 with Intel 
Graphics processor

-Client platforms: Intel(r) Core(tm) 5th generation (code name: Broadwell), 
6th generation (code name: Skylake), 7th generation (code name: Kabylake) and 
7th SoC generation (code name: Broxton), the Broxton is new supported platform



Guest Operation System Validated:

-Windows7 32-bit, Window7 64-bit, Windows8.1 64-bit, Windows10 64-bit

-Ubuntu 18.04 64-bit



Major Changes since Q1'2018 Release:

-This update is based on kernel version 4.17 and Qemu version 2.12.

-Add the Broxton platform preliminary support for KVMGT.

-Improve stability of dma-buf feature with some GPU reset issues be fixed.

-More bug fixing and code refinement, please refer to git log.



Limitation or known issues:

-Due to graphics hardware resource limitation, the maximum number of 
Windows VM is 7.

-The pre-defined type 1, 2 or 4 of vGPU must be created for VM to install 
Windows 7 32-bit. vGPU type 8 is not allocated to have enough graphics resource 
to support Windows 7 32-bit.

-Some 3rd party applications/tools like GPU_Z, Passmark 9.0 running in 
Windows VM may meet BSOD error. The workaround is to add "kvm.ignore_msrs=1" in 
host kernel's command line to avoid this.

-There are still instability issues about Guest VM stability while the 
IOMMU feature is enabled on a few Broadwell and Kabylake machines. The 
workaround is to turn off IOMMU on Intel graphics device by adding 
"intel_iommu=igfx_off"  in Host kernel's command line.
-For Broxton, only Linux guest is currently supported, and the Linux guest 
kernel must be the same as the host kernel.

Important Note:

The KVMGT 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 KVMGT project.
