This should be good for radeonsi to implement the feature as well.
FWIW:

Little bikeshed comment.
I'm a little iffy about using a mask instead of an enum for priority
values. It limits the flexibility on the number of levels drastically.
Since you can't really be at two different priority levels
simultaneously, this seems like a waste.
As long as we don't have a need for more than a handful of priority
levels this should be okay. And if the requirement changes, it can be
dealt with in the future.
Regards,
Andres
