Before we initialize schedulers we must know which reset
domain are we in - for single device there iis a single
domain per device and so single wq per device. For XGMI
the reset domain spans the entire XGMI hive and so the
reset wq is per hive.

Maybe better put that into amdgpu_ring.c. But not really a hard
requirement, more a gut feeling.

Probably better to set that in the caller and drop the parameters
from the amdgpu_fence_driver_init_ring() function completely.
Christian.
I noticed that at least num_hw_submission is validated within the
function so not sure we should then discard the parameters.
Good point. It also doesn't make sense to move this check up because the
power of two requirement comes from the fences, doesn't it?
Ok in this case just keep it like it is.
Christian.
