We do support other GPUs but currently that's through our LibVF.IO pathway (currently supports Nvidia, Intel, and some AMD GPUs):

A full list of supported devices is available here:

There are some limitations involved in LibVF.IO such as pre-defined mdev types. GVM is entirely free/libre open source software and it supports arbitrary mdev types. :)

We'll do our best to add more supported vendors to GVM/mdev-gpu in the near future.
