Again as in your other comment GVM does not actually have anything to do with LibVF.IO right now. They don't even work together. GVM/Mdev-GPU is actually a free software component that virtualizes GPUs, not a wrapper for QEMU/KVM. That's misinformation.

GVM/Mdev-GPU is over here - not in the LibVF.IO codebase which you link to:

https://github.com/Arc-Compute/Mdev-GPU

https://docs.linux-gvm.org/mdev-gpu/

Also Intel's SR-IOV isn't my code. You have to ask them about that.
