This series implements set of testcases for verifying data sampled
through i915 perf/DAPC feature. It tests validity of association of
OA with correct engine/stream, ctx id, pid, tag, timestamps, mmio
samples w.r.t execbuf begin and end. It also adds a testcase to
verify concurrent operation of two stream.
Currently MMIO testcase is failing as HW is reading the RC6 register
as zero if the stream has OA sampling also ON. Testcase however passes
if we sample MMIO along with Timestamps. Need to investigate this more.
More subtests to be added to test the proper interleaving of CS
and OA reports based on timestamps by varying the periodic timer for
OA reports.
