Does this work properly for multiple GPUs?  E.g., if one is suspended
and another is not?  E.g., PX laptops where we runtime suspend the
dGPU while the APU is still running.

Hi Alex,

As far as I know, we never tested suspend/resume on the setting you 
mentioned. Theoretically it should work.

When I read the code now, I was wondering whether we should stop kfd 
before amdgpu_bo_evict_vram() and amdgpu_fence_driver_suspend(). If 
that's not needed, it may make more sense to stick to the previous 
design which kept the kfd suspend/resume inside your IP block 
suspend/resume.

Regards,

Yong

Are the kfd s/r entry points global or per GPU?  If you have two GPUs
and you suspend one, will it suspend the entire kfd?  I'm fine with
the change, it's no worse than the current situation.  Mostly just
curious.

I think it makes more sense to put the kfd calls in the common device
s/r code rather than in the soc specific ip functions.  Change is:

kfd s/r is per GPU. If we suspend only one out of two GPUs, the other 
one will keep working.
