On the other hand, we will eventually get all codes upstreamed into mainline kernel/hypervisor, and it will effectively make the ISO unnecessary - that is, running a KVM guest with Intel vGPU support would be quite easy. Hongbo will make the decision if we should update the ISO before its being obsoleted by the upstreaming effort :-) > Thanks again to you and the entire iGVT-g team for working so hard on > this project! > > Best regards, > GizmoChicken Personally I'm not even the one who made the most incredible thing happen, but hey, I'm pretty sure that everyone in the team will be flattered by your compliment and thrilled to have so passionate users .. :-) -- Thanks, Jike > > > On Sun, Nov 6, 2016 at 10:23 AM, Jike Song <jike.song(a)intel.com&gt; wrote: >> Hi all, >> >> While spending efforts for upstreaming, we are pleased to announce another 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 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. >> >> Repositories: >> >> - 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: KabyLake, 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.
