perf list: Extend raw-dump to certain kind of events
Extend 'perf list --raw-dump' to 'perf list --raw-dump [hw|sw|cache |tracepoint|pmu|event_glob]' in order to show the raw-dump of a certain kind of events rather than all of the events. 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.
