Kan Liang 91a8c5b840 perf intel-pt: Always set no branch for dummy event ... An earlier kernel patch allowed enabling PT and LBR at the same time on Goldmont. commit ccbebba4c6 ("perf/x86/intel/pt: Bypass PT vs. LBR exclusivity if the core supports it") However, users still cannot use Intel PT and LBRs simultaneously. $ sudo perf record -e cycles,intel_pt//u -b -- sleep 1 Error: PMU Hardware doesn't support sampling/overflow-interrupts. PT implicitly adds dummy event in perf tool. dummy event is software event which doesn't support LBR. Always setting no branch for dummy event in Intel PT.
