Re: [Intel-gfx] [Announcement] 2016-Q1 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 - Kernel: https://github.com/01org/igvtg-kernel (2016q1-4.3.0 branch) Xen: https://github.com/01org/igvtg-xen (2016q1-4.6 branch) Qemu: https://github.com/01org/igvtg-qemu (2016q1-2.3.0 branch) This update consists of: -Windows 10 guest is preliminarily supported in this release. -Implemented vgtbuffer(Indirect display) feature on SKL platform. -Backward compatibility support 5th generation (Broadwell) -Increased VGT stability on SKL platform -Kernel updated from drm-intel 4.2.0 to drm-intel 4.3.0 -Xen updated from Xen 4.5.0 to Xen 4.6.0 -Qemu updated from 1.6 to 2.3 Known issues: -At least 2GB memory is suggested for VM(win7-32/64, win8.1 64) to run most 3D workloads. -Windows 7 GFX driver upgrading only works on Safe mode. -Some media decode can't work well (will be resolved in the next version Windows GFX driver). -Windows8 and later Windows fast boot is not supported, whose workaround is to disable power S3/S4 in HVM file by adding "acpi_s3=0, acpi_s4=0" -Sometimes when dom0 and guest have heavy workload, i915 in dom0 will trigger a false graphics reset. The workaround is to disable dom0 hangcheck in dom0 grub file by adding "i915.enable_hangcheck=0" Next update will be around early July, 2016.
