Note Intel GVT-g is only available on <=Gen9 GPU's. Gen11 and 12 are not supported.

It also works on Intel's ARC and DG1/DG2 discrete GPUs.

Our software also works on most consumer Nvidia cards and also some consumer AMD cards.

Do you have any specific knowledge of Intels support for graphics virtualization on ARC GPU's?

What are the security implications of LibVF and would it be compatible with the QubesOS security model?

Ya, they are enabling GVT-g on all their GPUs going forward including the ARC branded devices (not just the embedded GPUs with Xe branding). They have no plans to lock out those features on consumer devices. In fact I bought a $700 computer from Best Buy that had an intel discrete GPU in it for development. :)

Ya, I have been talking with the Qubes guys. I'm trying my best to figure out how I can help them ship something with LibVF.IO but they are currently based on Xen which uses Libxl rather than VFIO which may present some challenges.

Just last week Intel confirmed to us that GVT-g is dead with their iris/xe generation of graphics and won't come back. Are you sure you didn't mean GVT-d?

Do you have a source for that intel confirmation?

It was on a call, but a quick search just came up with this:

GVT-G has hard resolution limitations and was never stable with QEMU on Linux

GVT-g uses KVMgt. Intel has not yet upstreamed their patches.
