Hi,

nvidia:
At the moment, nvidia gpu passthrough is not supported by upstream. I
have a small patch stack for nvidia [1] but it's not well tested and I
don't know for which guests and cards it works.

amd:
Should work properly on 13.2, 14.0 and onward. Note that there's a
hardware bug on many cards [2].

intel:
Requires a patched EDKII firmware [3]. Unfortunately, it's not merged
yet. Btw. even if you only have an Intel card available you can use it
for GPU passthrough.
