[Intel-gfx] [PATCH 14/15] drm/i915: Mechanism to forward clock monotonic raw time in perf samples

2016-11-04 Thread sourab . gupta
From: Sourab Gupta Currently, we have the ability to only forward the GPU timestamps in the samples (which are generated via OA reports or PIPE_CONTROL commands inserted in the ring). This limits the ability to correlate these samples with the system events. If we scale
