Intel Prepares For Mainline GVT-g Graphics Virtualization Support

Intel's open-source developers maintaining GVT-g for Linux graphics virtualization support for their hardware are working on migrating their development workflow from this code that's been out-of-tree since its inception to now being mainline.

With the imminent Linux 4.10 release, the initial pieces of GVT support are mainline for allowing Xen/KVM guest VMs to access the Intel graphics hardware of the host. All the pieces are coming together but it still might be a few months before everything is usable for production standards and running smoothly and mainline throughout all the interconnected components of the open-source Linux virtualization stack.

There is more details on the experimental virtual GPU support in Linux 4.10 via this article for those behind on their Phoronix reading.

Intel's Hongbo Wang laid out more details today on their transition period for Intel Graphics Virtualization Technology as everything works to be mainline. As expected, they will be shifting their development focus to the upstream repositories. For those interested in GVT-g and wishing to learn more details, their transition plan was laid out this morning in this mailing list message.

Once everything is settled with GVT-g in a kernel release or two, I plan to deliver some Intel graphics virtualization benchmarks on Phoronix.
