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.

Re: [iGVT-g] [Intel-gfx] [Announcement] 2015-Q3 release of XenGT - a Mediated Graphics Passthrough Solution from Intel
by Jike Song
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); and the core logic can be easily ported to other hypervisors.
Repositories
Kernel: https://github.com/01org/igvtg-kernel (2015q3-3.18.0 branch)
Xen: https://github.com/01org/igvtg-xen (2015q3-4.5 branch)
Qemu: https://github.com/01org/igvtg-qemu (xengt_public2015q3 branch)
This update consists of:
- XenGT is now merged with KVMGT in unified repositories(kernel and qemu), but currently
different branches for qemu. 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.

intel vgpu / pass-through chipset requirements
by Gerd Hoffmann
Hi,
I'm looking over the tweaks the kvmgt qemu code is doing to the intel
chipset emulation, for vgpu (and IIRC the requirements for pass-through
are very simliar). I know you guys are working on untangling chipset
and graphics devices on the hardware and guest driver side to make all
this less messy, so I want go over this and check what is actually
needed and what can possibly go away ...
(1) Host bridge
===============
Starts as i440fx device. seabios signals when POST is done. Device
changes identity then, some config space registers (device id, gfx
config) are filled from host then.
Is there anything beside the config space bits?
I've seen vgpu simply copies over the gfx config registers too instead
of filling in there something virtual, are there any differences between
vgpu and pass-through?
The hack to change device identity needs to go away for merging stuff
upstream. So seabios needs some way to figure what the hostbridge
really is (i440fx / q35) to initialize it properly, without playing
masquerade games. One possible option would be a special subsystem id.
Comments? Other suggestions?
(2) ISA bridge
==============
Lives at 1f.0. Device id filled from host. Looks pretty much like a
dummy device, seems it doesn't actually do anything. Did I miss
something? If not: What this is needed for? Get past guest driver
sanity checks?
(3) opregion
============
what is this exactly? Paravirtual communication path between host and
guest igd driver? If so: Can this be moved to vfio?
cheers,
Gerd

If such a feature added to VFIO, I'm pretty sure it will do good to
GVT-d, the passthrough implementation. As for OpRegion for GVT-g, since
it's virtualized, we are capable to emulate the OpRegion in QEMU as a
malloced 8192-byte memory region, no need to expose the physical one.
BTW, if you want to add this feature, where would you place it?
drivers/vfio/pci/ or elsewhere?

[XenGT][IGVT-g] Device model creation failed
by Oleksii Kurochko
Hello!
We are going to use XenGT on Intel Atom based board(VTC-1010, with 4GB RAM).
For this purpose we use next repos:
xen - https://github.com/01org/Igvtg-xen
dom0 (ubuntu linux, 1024MB or 2048MB ) -
https://github.com/01org/Igvtg-kernel
domU (android-x86, rest memory excluding xen heap, xen, about 1.7GB RAM ) -
same kernel, with some config changes
Guest domain are going to be started in HVM mode.
We follow iGVT-g setup guide (
https://github.com/01org/Igvtg-kernel/blob/2015q3-3.18.0/iGVT-g_Setup_Gui...)
and successfully setup dom0 with iGVT.
But, when we are going to start domU (with enabled vgt=1 switch) domain
creation failed with follow log:
> vtc@vtc-VTC1010:~$ sudo xl -vvv create -c ./a.cfg

Without this flag - are all ok, domain created and running normally.
Do you have any ideas about this issue?
Thank you.

3.11.6 kernel is a very very old version, you can upgrade to 2015Q3 release version for a try.

Are you using KVM or Xen? What does dmesg say?
Can you post the output of "dmesg | grep vgt"?

I've got a Broadwell machine I'm attempting to run XenGT on, but when
I create a Windows domain, as soon as the virtualized graphics adapter
starts initializing, the domain crashes, X crashes and restarts, then
the kernel crashes. Here is the output of dmesg right after creating
the domain:

Are you using KVM or Xen? What does dmesg say?
Can you post the output of "dmesg | grep vgt"?

I've got a Broadwell machine I'm attempting to run XenGT on, but when
I create a Windows domain, as soon as the virtualized graphics adapter
starts initializing, the domain crashes, X crashes and restarts, then
the kernel crashes. Here is the output of dmesg right after creating
the domain:

Are you using KVM or Xen? What does dmesg say?
Can you post the output of "dmesg | grep vgt"?

I've got a Broadwell machine I'm attempting to run XenGT on, but when
I create a Windows domain, as soon as the virtualized graphics adapter
starts initializing, the domain crashes, X crashes and restarts, then
the kernel crashes. Here is the output of dmesg right after creating
the domain:

Are you using KVM or Xen? What does dmesg say?
Can you post the output of "dmesg | grep vgt"?

I've got a Broadwell machine I'm attempting to run XenGT on, but when
I create a Windows domain, as soon as the virtualized graphics adapter
starts initializing, the domain crashes, X crashes and restarts, then
the kernel crashes. Here is the output of dmesg right after creating
the domain:
