[Intel-gfx] [PATCH v5 09/11] drm/i915: add oa_event_min_timer_exponent sysctl

2016-09-14 Thread Robert Bragg
The minimal sampling period is now configurable via a dev.i915.oa_min_timer_exponent sysctl parameter. Following the precedent set by perf, the default is the minimum that won't (on its own) exceed the default kernel.perf_event_max_sample_rate default of 10 samples/s. Signed-off-by: Robert Br
