[Intel-gfx] [PATCH v2] drm/i915/perf: per-gen timebase for checking sample freq

2017-04-05 Thread Robert Bragg
An oa_exponent_to_ns() utility and per-gen timebase constants where recently removed when updating the tail pointer race condition WA, and this restores those so we can update the _PROP_OA_EXPONENT validation done in read_properties_unlocked() to not assume we have a 12.5MHz timebase as we did for
