Currently, for Gen11 and later (in Ice Lake), neither GVT-g nor SR-IOV-based GPU virt options are available. As we're several years past Gen11 launch, seems that Intel isn't interested in GPU virtualisation much anymore on a Linux host.

I'm happy to report that as of recently on 11th generation Intel Xe GPUs and later SR-IOV is now supported!!
Here's the commit to Intel i915 containing SR-IOV feature enablement! :)

Oh nice, will have to play with this once it reaches my distro. :)

We have tools to enable functionality up to Turing. Here's that post:
