So in GPU offload mode, how does amdkfd wake the GPU up to execute
stuff?
GPU offload is where the radeon GPU is a secondary GPU and we power it
down automatically.
Granted I think our powerdown should probably check if the GPU is executing
anything a bit more, but I don't think amdkfd can even wake it up to submit
work at the moment.
Dave.
