A few races and bugs in PMU busyness implementation are resulting in a wide range of IGT failures. This series addresses some failures that are easily reproduced. To repro the issues, we run a couple iterations of igt@perf_pmu@busy-hang followed by igt@perf_pmu@most-busy-idle-check-all test. v2: Review rework Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@xxxxxxxxx> Umesh Nerlige Ramappa (3): i915/guc: Reset engine utilization buffer before registration i915/guc: Ensure busyness counter increases motonically i915/guc: Accumulate active runtime on gt reset drivers/gpu/drm/i915/gt/intel_engine_types.h | 5 +++ .../gpu/drm/i915/gt/uc/intel_guc_submission.c | 41 ++++++++++++++++++- 2 files changed, 44 insertions(+), 2 deletions(-) -- 2.34.1
