IDG and Phoronix on Graphics
The xf86-video-intel 3.0 DDX driver has been in development the past two and a half years without seeing an official release.
Intel has released their first new versions of XenGT and KVMGT for 2016 for GPU virtualization solutions for Xen and KVM, respectively.
These Intel GPU virtualization solutions provide media pass-through of Haswell graphics cores and newer. A virtual GPU instance is exposed to each KVM/Xen VM for "a good balance among performance, feature, and sharing."
