Intel GVT in not working on Xen

by Asharaf Perinchikkal

Hi All, We are trying bring up xen 4.8 1 on 4th Generation Intel® Core™ i7 with Graphics Virtualization Technology(GVT) support. We are running two guest OS Automotive grade linux and Ubuntu 16.04 on Ubuntu 16.04 as host OS with Kernal Version 4.12.0-rc5+ on both guest and host. The Guests are up and running. But it seems graphics virtualization is not working, frame per seconds(fps) for some graphic application is very low[fps=3-5]. We followed all steps mentioned in setup guide [https://github.com/01org/gvt-linux/wiki/GVTg_Setup_Guide] and details are given below. Request support to resolve the issue.

[GVT-g] [Intel-gfx] [ANNOUNCE] 2017-Q2 release of XenGT (Intel GVT-g for Xen)

by Xu, Terrence

Hi all, We are pleased to announce an 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 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. GVT-g for Xen hypervisor is XenGT. Repositories - Xen : https://github.com/01org/igvtg-xen (tag: 2017-q2-xengt-stable-4.9) - Kernel: https://github.com/01org/gvt-linux/ (tag: 2017-q2-gvt-stable-4.11) - Qemu: https://github.com/01org/igvtg-qemu (tag: 2017-q2-stable-2.9.0) This update consists of: - GVT-g upgraded to new architecture which has been upstreamed from kernel 4.10. - QEMU version upgraded to 2.9 from 2.3. - Xen version upgraded to 4.9 from 4.6. - Supported server platforms: Intel(r) Xeon(r) E3_v4 and E3_v5 with Intel Graphics processor. - Supported client platforms: Intel(r) Core(tm) 5th generation (code name: Broadwell) and 6th generation (code name: Skylake). - Validated Guest OS: Windows7 32bit, Window7 64bit, Windows8.1 64bit, Windows10 64bit and Linux. - GVT-g only supports remote display not local display by this release. - Remote protocol: only guest-side remoting protocol is supported, host-side remoting connection like SPICE is working in progress. For example, user can use X11VNC for Guest Linux VM or TightVNC for Guest Windows VM. Limitation or known issues: - GVT-g can support maximum 7 Guest VMs due to host graphics resource limitation. When user runs 7 VMs simultaneously, host OS can only run in text mode. - In order to support Guest Windows7 32bit VM, user is recommended to add vgt_low_gm_sz=128 in HVM file because Guest Windows7 32bit VM needs more graphics resource than other Guest VM. - In order to support Guest VM high resolution and screen resolution adjustable in Guest Windows8.1 64bit VM and Guest Windows10 64bit VM, user is recommended to configure vgt_low_gm_sz=64 / 128 / 256 / 512 in HVM file to get larger VM aperture size. - In corner case, Guest Windows 8.1 64bit VM may be killed automatically by Xen when Guest VM runs into TDR. This issues happens only on Broadwell platform. - In corner case, Guest Windows VMs may be killed automatically by Xen when user shutdowns the last launched Guest Windows VM. This issues happens only on Broadwell platform. - In corner case, Guest Linux VM virtual display screen may freeze and not be able to recover when Guest VM runs into a TDR, but the Guest VM is still running and alive which can be accessed through SSH. Setup guide: https://github.com/01org/gvt-linux/wiki/GVTg_Setup_Guide This is the first GVT-g community release based on new Upstream architecture design, refer to the following document for new architecture introduction: https://01.org/igvt-g/documentation/intel-gvt-g-new-architecture-introduc...

[GVT-g] [Intel-gfx] [ANNOUNCE] 2017-Q2 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: 2017-q2-gvt-stable-4.11) - Qemu: https://github.com/01org/igvtg-qemu (tag: 2017-q2-stable-2.9.0) This update consists of: - GVT-g upgraded to new architecture which has been upstreamed from kernel 4.10. - QEMU version upgraded to 2.9 from 2.3 (There is no any specific code changes in QEMU for KVMGT, so people could directly use upstream QEMU as an alternative). - Supported server platforms: Intel(r) Xeon(r) E3_v4 and E3_v5 with Intel Graphics processor. - Supported client platforms: Intel(r) Core(tm) 5th generation (code name: Broadwell) and 6th generation (code name: Skylake). - Validated Guest OS: Windows7 32bit, Window7 64bit, Windows8.1 64bit, Windows10 64bit and Linux. - GVT-g only supports remote display not local display by this release. - Remote protocol: only guest-side remoting protocol is supported, host-side remoting connection like SPICE is working in progress. For example, user can use X11VNC for Guest Linux VM or TightVNC for Guest Windows VM. Limitation or known issues: - GVT-g can support maximum 7 Guest VMs due to host graphics resource limitation. When user runs 7 VMs simultaneously, host OS can only run in text mode. - In order to support Guest Windows7 32bit VM, user can only uses vGPU type1, type2, type4 not type8 because Guest Windows7 32bit VM needs more graphics resource than other Guest VM. - Some 3rd party applications/tools like GPU_Z, Passmark 9.0 may read/write GPU MSR directly, it will trigger VM BSOD since those MSRs are unhandled registers in KVMGT. The workaround is to set MSR read /write ignore flag to 1 in host grub file by adding "kvm.ignore_msrs=1". - In corner case, Guest Linux VM virtual display screen may freeze and not be able to recover when Guest VM runs into a TDR, but the Guest VM is still running and alive which can be accessed through SSH.

what can I do with GPU crashes/resets

by Nick S

Hi everybody, I am looking for suggestions how to troubleshoot my guest VM crashing or freezing host GPU. I am running the kernel from the gvt-stable-4.11 branch. When I run a certain game inside my virtual machine, it results in a GPU crash or reset message in dmesg output and a direct-x error in the host. It usually runs for several minutes and then produces the following dmesg output: [ 495.290792] [drm] GPU HANG: ecode 9:0:0x85ddfffb, reason: Hang on render ring, action: reset [ 495.290794] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 495.290795] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 495.290796] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 495.290797] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [ 495.290798] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 495.290856] drm/i915: Resetting chip after gpu hang [ 495.291399] [drm] RC6 on [ 495.306556] [drm] GuC firmware load skipped I am looking for suggestions how can I troubleshoot this. Is the code from gvt-stable-4.11 already merged into the upstream kernel so that I can file that bug report dmesg suggests? Thank you, Nick

Crystal Well / Haswell support

by Ahmad Jagot

Hello, What would be involved in bringing Haswell support back to iGVT-g? I personally have 2 Haswell-era systems bought specifically for playing with this technology. Unfortunately, it seems this is no longer possible, making my investment rather worthless. It is much harder to find machines (especially laptops) with newer-generation, eDRAM-equipped 'Iris Pro' class graphics -- hardware ideally suited to graphics virtualization -- whereas the similarly capable Iris Pro 5200 GPU is still very accessible (eg. in Apple hardware). I realize this is not the first time this has been raised ( https://lists.01.org/pipermail/igvt-g/2017-January/001075.html) -- Would Intel therefore be willing to bring back support for Haswell-era GPUs? Kind regards, Ahmad
