<p class="MsoPlainText">Hi all,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">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.

<p class="MsoPlainText">The news of this update:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"> - kernel update from 3.11.6 to 3.14.1<o:p></o:p></p>
<p class="MsoPlainText" style="text-indent:.5in">- 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<o:p></o:p></p>
<p class="MsoPlainText"> - Next update will be around early Jan, 2015<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">This update consists of:<o:p></o:p></p>
<p class="MsoPlainText"> - Windows HVM support with driver version 15.33.3910<o:p></o:p></p>
<p class="MsoPlainText"> - Stability fixes, e.g. stabilize GPU, the GPU hang occurrence rate becomes rare now<o:p></o:p></p>
<p class="MsoPlainText"> - Hardware Media Acceleration for Decoding/Encoding/Transcoding, VC1, H264 etc. format supporting<o:p></o:p></p>
<p class="MsoPlainText"> - Display enhancements, e.g. DP type is supported for virtual PORT<o:p></o:p></p>
<p class="MsoPlainText"> - 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<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Please refer to the new setup guide, which provides step-to-step details about building/configuring/running Intel GVT-g:<o:p></o:p></p>
