H A D | perf_event.h | diff 67266c1080ad56c31af72b9c18355fde8ccc124a Wed Nov 21 04:16:11 CST 2018 Jiri Olsa <jolsa@kernel.org> perf/x86/intel: Add generic branch tracing check to intel_pmu_has_bts()
Currently we check the branch tracing only by checking for the PERF_COUNT_HW_BRANCH_INSTRUCTIONS event of PERF_TYPE_HARDWARE type. But we can define the same event with the PERF_TYPE_RAW type.
Changing the intel_pmu_has_bts() code to check on event's final hw config value, so both HW types are covered.
Adding unlikely to intel_pmu_has_bts() condition calls, because it was used in the original code in intel_bts_constraints.
