[Intel-gfx] [PATCH v3 0/7] Enable OA unit for Gen 8 and 9 in i915 perf

[Robert Bragg]

Adds some R/Bs from from Matthew and some updates based on Matthew's feedback

Notably the 'Add OA unit support for Gen 8+' patch now avoids duplicating lots
of fiddly tail race workaround code by adding a vfunc for reading the OA tail
pointer register.

Robert Bragg (7):
  drm/i915: expose _SLICE_MASK GETPARM
  drm/i915: expose _SUBSLICE_MASK GETPARM
  drm/i915/perf: Add 'render basic' Gen8+ OA unit configs
  drm/i915/perf: Add OA unit support for Gen 8+
  drm/i915/perf: Add more OA configs for BDW, CHV, SKL + BXT
  drm/i915/perf: per-gen timebase for checking sample freq
  drm/i915/perf: remove perf.hook_lock
