[Nouveau] [RFC v2 0/6] PMU engine counters

[Karol Herbst]

reworked this series quite a lot.

Now we want the Host to configure the counters through the PMU.

The series isn't complete though because it needs:
1. reordering
2. better commit messages

but I felt like sending those out before doing a final version.

I also found some weird register overwriting issue on the PMU I have to track
down, because it interfers with the counter read out. I am quite sure it is not
cause by any of my changes.

Anyway this feature is required for implementing dynamic reclocking. As a side
effect it shows us a coarse load of several engines, allthough the counters can
only report "idle" or "non-idle".

Karol Herbst (6):
  pmu/fuc: add macros for pdaemon pwr counters
  pmu/fuc: read out counters and store them
  pmu/fuc: implement GET_SLOTS
  pmu/fuc: implement SET_SLOT
  nouveau/debugfs: add interface for current load
  pmu: setup counters
