We wanted to use MI50s at work because it was promised they can do SRIOV, but we never got any further with AMD support than "it should work". They took ages to respond, and could not tell what was wrong from the extensive logs and hwinfo we provided them with.

Also the PCI reset bug that plagued multiple generations. There's a guy maintaining a kernel module that works around that issue in a whacky way. According to his research and reverse engineering, AMD could fix that with a firmware update to those cards. Even got in contact with AMD engineers briefly and outlined what the problem was. Then radio silence, and a couple months later AMD added a very similar workaround in their kernel module, the amdgpu driver. It's just that a fix in there doesn't make any sense whatsoever, because you need that fix when you do PCI passthrough, in which case you explicitly do not load the amdgpu module, as you don't use the GPU on the host machine but, well, pass it through to the VM.
