Example Before this patch: $perf list --raw-dump hw branch-instructions branch-misses bus-cycles cache-misses cache-references cpu-cycles instructions stalled-cycles-backend stalled-cycles-frontend alignment-faults context-switches cpu-clock cpu-migrations emulation-faults major-faults minor-faults page-faults task-clock ... ... writeback:writeback_thread_start writeback:writeback_thread_stop writeback:writeback_wait_iff_congested writeback:writeback_wake_background writeback:writeback_wake_thread As shown above, all of the events are printed. After this patch: $perf list --raw-dump hw branch-instructions branch-misses bus-cycles cache-misses cache-references cpu-cycles instructions stalled-cycles-backend stalled-cycles-frontend As shown above, only the hw events are printed.
