8th/9th gen processor with current kernel/qemu?

by Florian Bauer

Hi, I want to try out igvt on my laptop. After reading the docs I have some questions: Documentation* lists support for 5th to 7th generation only. Is this still up-to-date? What about 8th gen? Is is not supported at all or just not considered stable enough? The docs also suggest building a patched 4.14 kernel. Is this still required or does the 4.18 or 4.19 kernel already contain all the patches? Same question for qemu: Are all required patches upstreamed to 3.0 or do I need to stick to the patched 2.12 one? * https://github.com/intel/gvt-linux/wiki/GVTg_Setup_Guide regards, Florian

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

by 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. Useful links: - Setup guide: https://github.com/01org/gvt-linux/wiki/GVTg_Setup_Guide - New upstream architecture design introduction: https://01.org/igvt-g/documentation/intel-gvt-g-new-architecture-introduc... - Please subscribe to join the mailing list if you want to learn more about GVT-g project: https://lists.01.org/mailman/listinfo/igvt-g - Please subscribe to join the mailing list if you want to contribute/review latest GVT-g upstream patches: https://lists.freedesktop.org/mailman/listinfo/intel-gvt-dev - Official GVT-g portal: https://01.org/igvt-g - More information about background, architecture and others about Intel GVT-g, can be found at: http://www.linux-kvm.org/images/f/f3/01x08b-KVMGT-a.pdf https://www.usenix.org/conference/atc14/technical-sessions/presentation/tian 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.

i5-8259U with Iris Plus Graphics 655 (0x3EA5) supported?

by Jonas Grande

Hey, This is probably a dumb question but is GVT-g supported on the 8th gen i5-8259U processor (present in Intel NUC8i5)? (I want to try GVT-g for running macOS under KVM but I'm unsure if I should get an Intel NUC7i5 or a NUC8i5.) According to the below doc it has an Iris Plus Graphics 655 with device ID 0x3EA5. https://ark.intel.com/products/135935/Intel-Core-i5-8259U-Processor-6M-Ca... <https://ark.intel.com/products/135935/Intel-Core-i5-8259U-Processor-6M-Ca...> From other posts I've understood that Coffee Lake and/or 8th gen CPUs are not supported, e.g. https://lists.01.org/pipermail/igvt-g/2018-October/001439.html <https://lists.01.org/pipermail/igvt-g/2018-October/001439.html> https://github.com/intel/gvt-linux/wiki/GVTg_Setup_Guide <https://github.com/intel/gvt-linux/wiki/GVTg_Setup_Guide> However, since the i5-8259U CPU has an Iris Plus Graphics GPU -- similar to the i5-7260U (present in e.g. NUC7i5) -- I'm hoping that it might be supported despite being an 8th gen CPU? :) (..since many other CFL processors appear to feature "UDH Graphics NNN", which I understand is not supported) Here's what https://github.com/intel/gvt-linux/blob/gvt-staging/include/drm/i915_pcii... <https://github.com/intel/gvt-linux/blob/gvt-staging/include/drm/i915_pcii...> says about the Iris Plus Graphics 655 (0x3EA5): /* CFL U GT3 */ #define INTEL_CFL_U_GT3_IDS(info) \ INTEL_VGA_DEVICE(0x3EA5, info), /* ULT GT3 */ \ INTEL_VGA_DEVICE(0x3EA6, info), /* ULT GT3 */ \ INTEL_VGA_DEVICE(0x3EA7, info), /* ULT GT3 */ \ INTEL_VGA_DEVICE(0x3EA8, info) /* ULT GT3 */ For reference, here's what the same file says for the supposedly supported 7th gen i5-7260U (Iris Plus Graphics 640, ID 0x5926): #define INTEL_KBL_GT3_IDS(info) \ INTEL_VGA_DEVICE(0x5923, info), /* ULT GT3 */ \ INTEL_VGA_DEVICE(0x5926, info), /* ULT GT3 */ \ INTEL_VGA_DEVICE(0x5927, info) /* ULT GT3 */ Thank you in advance and have a nice weekend! -- J.
