AFAIK at this point AMD APUs are simply CPU + GPU. Even though they're
in the same die, they're basically different devices. So for the GPU
part, treat it like any other GPU. Which means you could PROBABLY
passthru it to ONE domU, but that's it.

AMD's plan for the future is make a chip which can function as CPU or
GPU as needed, but that hasn't happened yet.
