Hi all,
We're pleased to announce an update to Intel Graphics Virtualization Technology (Intel GVT-g, formerly known as XenGT). Intel GVT-g is a complete vGPU solution with mediated pass-through, supported today on 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. Though we only support Xen on Intel Processor Graphics so far, the core logic can be easily ported to other hypervisors.
The news of this update:
- Project code name is "XenGT", now official name is Intel Graphics Virtualization Technology (Intel GVT-g)
- Currently Intel GVT-g supports Intel Processor Graphics built into 4th generation Intel Core processors - Haswell platform
- Moving forward, XenGT will change to quarterly release cadence. Next update will be around early October, 2014.
This update consists of:
- Stability fixes, e.g. stable DP support
- Display enhancements, e.g. virtual monitor support. Users can define a virtual monitor type with customized EDID for virtual machines, not necessarily the same as physical monitors.
- Improved support for GPU recovery
- Experimental Windows HVM support. To download the experimental version, see setup guide for details
- Experimental Hardware Media Acceleration for decoding.
Please refer to the new setup guide, which provides step-to-step details about building/configuring/running Intel GVT-g:
https://github.com/01org/XenGT-Preview-kernel/blob/master/XenGT_Setup_Guide.pdf
The new source codes are available at the updated github repos:
Linux: https://github.com/01org/XenGT-Preview-kernel.git
Xen: https://github.com/01org/XenGT-Preview-xen.git
Qemu: https://github.com/01org/XenGT-Preview-qemu.git

Perhaps the info is available somewhere already (in which case, sorry),
but what's the (if any) upstreaming plan/status/ETA?
I think this info could well be part of these updates. :-)
Thanks and Regards,
Dario

Thanks for your opinion :-)
We plan to start the upstreaming work in this quarter. For your information,
Wei's IOREQ server enhancement(aka "Extend ioreq-server to support page write protection")
is actually part of the upstreaming effort.
Patches for different components will be sent out later.

Hi all,
We're pleased to announce a public release to Intel Graphics Virtualization Technology (Intel GVT-g, formerly known as XenGT). Intel GVT-g is a complete vGPU solution with mediated pass-through, supported today on 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. Though we only support Xen on Intel Processor Graphics so far, the core logic can be easily ported to other hypervisors.
The news of this update:
- kernel update from 3.11.6 to 3.14.1
- We plan to integrate Intel GVT-g as a feature in i915 driver. That effort is still under review, not included in this update yet
- Next update will be around early Jan, 2015
This update consists of:
- Windows HVM support with driver version 15.33.3910
- Stability fixes, e.g. stabilize GPU, the GPU hang occurrence rate becomes rare now
- Hardware Media Acceleration for Decoding/Encoding/Transcoding, VC1, H264 etc. format supporting
- Display enhancements, e.g. DP type is supported for virtual PORT
- Display port capability virtualization: with this feature, dom0 manager could freely assign virtual DDI ports to VM, not necessary to check whether the corresponding physical DDI ports are available
Please refer to the new setup guide, which provides step-to-step details about building/configuring/running Intel GVT-g:
https://github.com/01org/XenGT-Preview-kernel/blob/master/XenGT_Setup_Guide.pdf
The new source codes are available at the updated github repos:

Thanks for this very good project.
I did a fast look to xen patch about it, I have some small advices:
change to tools/examples/xmexample.hvm should be to
tools/examples/xlexample.hvm instead since is implemented in xl and not xm.
I think is good rebase the patch to latest xen-unstable git that have
many changes, for better reviews and for propose it upstream for xen 4.6
if will be good.
Thanks for any reply and sorry for my bad english.
