[Intel-gfx] [PATCH i-g-t 2/9] tests/perf: Test i915 assisted command stream based perf metrics capture

2017-09-13 Thread Sagar Arun Kamble
This tests different performance metrics being streamed by i915 driver. This feature in i915 also referred as Driver Assisted Performance Capture (DAPC) provides userspace an ability to sample the OA reports at execbuf boundaries and associate other metadata like CTX ID, PID, TAG with each sample.
