Re: [iGVT-g] [ANNOUNCE][RFC] KVMGT - the implementation of Intel GVT-g(full GPU virtualization) for KVM

by Jike Song

Hi all, We are pleased to announce another update of Intel GVT-g for KVM. 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. KVM is supported by Intel GVT-g(a.k.a. KVMGT). Repositories Kernel: https://github.com/01org/igvtg-kernel (2015q3-3.18.0 branch) Qemu: https://github.com/01org/igvtg-qemu (kvmgt_public2015q3 branch) This update consists of: - KVMGT is now merged with XenGT in unified repositories(kernel and qemu), but currently different branches for qemu. KVMGT and XenGT share same iGVT-g core logic. - PPGTT supported, hence the Windows guest support - KVMGT now supports both 4th generation (Haswell) and 5th generation (Broadwell) Intel Core(TM) processors - 2D/3D/Media decoding have been validated on Ubuntu 14.04 and Windows7/Windows 8.1 Next update will be around early Jan, 2016. Known issues: - At least 2GB memory is suggested for VM to run most 3D workloads. - 3Dmark06 running in Windows VM may have some stability issue. - Using VLC to play .ogg file may cause mosaic or slow response.

XenGT and KVMGT share same iGVT-g core logic. - fix sysfs/debugfs access seldom crash issue - fix a BUG in XenGT I/O emulation logic - improve 3d workload stability Next update will be around early Jan, 2016. Known issues: - At least 2GB memory is suggested for VM to run most 3D workloads. - Keymap might be incorrect in guest. Config file may need to explicitly specify "keymap='en-us'". Although it looks like the default value, earlier we saw the problem of wrong keymap code if it is not explicitly set. - When using three monitors, doing hotplug between Guest pause/unpause may not be able to lightup all monitors automatically. Some specific monitor issues. - Cannot move mouse pointer smoothly in guest by default launched by VNC mode. Configuration file need to explicitly specify "usb=1" to enable a USB bus, and "usbdevice='tablet'" to add pointer device using absolute coordinates. - Resume dom0 from S3 may cause some error message. - i915 unload/reload cannot works well with less than 3 vcpu when upowerd service was running - Unigen Tropics running in multiple guests will cause dom0 and guests tdr.

KVMGT support Intel VCA?

by Eddie Yen

Hello, everyone. I had another question again, as title that I survey these days that Intel also released VCA card. It included 3x E3-1285 v4 /w Iris Pro Graphics P6300. Does KVMGT support this device?

Xeon e3 chips

by Brad Bozarth

I was looking at Skylake chips on which to run iGVT, and was interested in the e3-1275 v5. I noticed on Intel's site, all the i-series consumer chips have 64GB listed as "Graphics Video Max Memory," whereas the e3-12xx v5 Xeon chips have 1.7GB listed. Does that present a problem for running iGVT? The e3-12xx series seems to be the only ECC supporting chip that has integrated graphics, has iGVT been successfully run on it? Thanks, Brad

by Zhou, Chao

Hi all, If you just want to try and experience what Intel(r) GVT-g is, now you don't need to build source code from scratch. All you need is to plug-in a USB flash disk into an Intel 5th Generation Core platform machine (code name: Broadwell), boot from this USB disk. We're pleased to announce that a GVT-g demo ISO is ready for download, use this ISO file, you can select either booting from a USB disk as a LiveCD or deploying GVT-g into the computer Hard Disk. Features: - Support both XenGT and KVMGT LiveCD - Support deployment of XenGT and KVMGT in local Hard Disk - Include one Dom0/Host (Ubuntu 14.04) and one Guest Linux (Ubuntu 14.04) - Linux 3D workload pre-installed in Linux Guest. - Shortcut to launch Guest or to start 3D workload User guide: - Detailed User Guide please refer to the README inside the ISO. Supported hardware: Intel 5th Gen, Broadwell Download link: https://sourceforge.net/projects/gvt-g-iso Project portal: Official iGVT-g portal: https://01.org/igvt-g If you have any questions, please subscribe to join the mailing list: https://lists.01.org/mailman/listinfo/igvt-g Note: The XenGT and 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 XenGT and KVMGT project.

KVMGT

by info＠delphi-real-estate.com

I am trying to figure out how to set up a KVM guest, and it seems hopelessly complicated without virt-manager. Host is RedHat 7.2 Minimal running the iGVT 4.3 kernel and QEMU. Guests are all LVs in one VG, and are set up and ready to go. NICs are SR-IOV VFs set up and ready to go, 1 or 2 per VM. But in the Setup Guide, I just don't have the days it would take to analyze, learn, fail, and experiment every in and out of creating a guest. (Section 4.1.2) And that's assuming the docs are up to date, which it appears they may not be. There doesn't seem to be a way to connect a specific NIC (MACs are randomized every boot with VFs) to a given VM, given the options available. Then there's setting up video which seems hopelessly complicated. I have only two VMs that need video; the rest can be SSH. I don't have a GUI on the host as this is a Minimal install. Is there a quicker way to get running?

(doesn't boot at all) With -vgt_low_gm_sz 128 -vgt_high_gm_sz 384 VM is running quite good but sometimes I get: kwi 20 01:18:42 cc_l540_arch kernel: [drm:i915_gem_object_do_pin [i915]] *ERROR* fail to allocate space from whole GM space, size: 8 I have seen some info that min GM size is 64MB for linux, and 128MB for Windows, so even 256MB should be fine for one Win VM guest. It looks like my win7 VM needs more than 128MB of gm? And it looks like my host also uses 128MB of gm, so only 128MB is available to VM? In general - what affects GM usage on host and VM? Could you point me to some info about it? Thanks, and regards.

gpu hang when using Windows 7 as guest

by Michael Müller

Hi, I am trying to use Windows 7 as guest and don't have much luck. After installing the driver in the guest system, it won't boot Windows any more and gets stuck while/after displaying the Windows logo. The dmesg output contains information about an untracked MMIO write, followed by a gpu hang. I attached the full output as file. I am also unable to terminate qemu properly after this (needs kill -9). Information about my setup: CPU: i7-4790K Kernel branch: 2016q1-4.3.0 Kernel cmdline (relevant part): i915.enable_vgtbuffer=1 intel_iommu=igfx_off conring_size=4M i915.propagate_monitor_to_guest=0 i915.enable_cmd_parser=0 Qemu branch: 2016q1-2.3.0 Qemu cmdline: qemu-system-x86_64 -m 2048 -enable-kvm -M pc -machine kernel_irqchip=on -vgt -vga vgt -vgt_low_gm_sz 128 -vgt_high_gm_sz 384 -vgt_fence_sz 4 -drive file=win7.qcow2,if=virtio -net nic,model=virtio -net user -usbdevice tablet -soundhw ac97 -smp 2 -vgt_monitor_config_file ./monitor.config -display sdl The monitor.config is copied from the setup guide. Windows driver version: 15.40.4352 Not sure if it makes a difference, but I am not using the intel gpu for rendering on my host system. I slightly modified the vgt ui code to fallback to mmap-ing the dma buffer and transferring the texture content using glTexImage2D when the EGL_MESA_drm_image extension is not available. This allows me to use the egl code with my nvidia card. The hang is unrelated to these changes though as it also happens with an unmodified qemu version. If anyone is interested in it, i can share a patch. Regards, Michael

Problem about setting up Windows guest

by moreD

Hi, I'm setting up a Windows 10 guest using 2015q4 release but having problem on installing driver. Windows boots normally while using Microsoft's basic video adaptor driver, but it always turned to black screen while installing intel gfx driver and stuck at windows logo when rebooting (I guess it is the time it loads intel driver). My system configuration is as follow: Lenovo thinkpad t440s intel i7-4600u (haswell) with vt-d a nvidia gt730m dGPU, but it won't boot whether pass-through it or not I'm running Debian sid and I've tried both KVMGT and XenGT. my qemu args when using KVMGT are: -cpu host -smp 4 -enable-kvm -m 4096 -M pc -machine kernel_irqchip=on -hda ./win10.qcow2 -s -v gt -vga vgt -vgt_low_gm_sz 256 -vgt_high_gm_sz 384 -vgt_fence_sz 4 -net nic,model=e1000 -net user -soundhw hda And my dmesg until stuck: [ 0.000000] pcpu-alloc: s93208 r8192 d29672 u524288 alloc=1*2097152 [ 0.000000] pcpu-alloc: [0] 0 1 2 3 [ 0.000000] Built 1 zonelists in Node order, mobility grouping on.

Code 12 while using QEMU compositor mode

by Eddie Yen

Hello, everyone. Today I'm tried the 2016Q1 version of KVMGT already, but I got code 12 error on my P6300 in Windows 7 Guest when I try on QEMU compositor. Here is some information about my setup, GRUB： GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=igfx_off i915.hvm_boot_foreground=1 i915.enable_cmd_parser=0 loglvl=all guest_loglvl=all conring_size=4M noreboot i915.enable_vgtbuffer=1 i915.propagate_monitor_to_guest=0" QEMU cmd： #/bin/sh qemu-system-x86_64 -m 8192 -smp 3 \ -enable-kvm \ -M pc -machine kernel_irqchip=on \ -hda /home/ubuntu/test.img \ -net nic,macaddr=52:54:00:12:34:56 -net tap,script=/home/ubuntu/qemu-ifup \ -vgt -vga vgt -vgt_low_gm_sz 128 \ -vgt_high_gm_sz 384 -vgt_fence_sz 4 And there is the dmesg message when starting Guest: http://pastebin.com/HfpWeXmh There is one thing I feel strange is, when I configure the QEMU, I got this at beginning "Intel GVT-g compositor egl will be disabled due to EGL library missed." And I check configure result, found that: Intel GVT-g support yes Intel GVT-g compositor egl no Intel GVT-g compositor blt yes Is that cause Code 12 issue? Many thanks, Eddie.
