    perf list: Extend raw-dump to certain kind of events · 5ef803ee
    Yunlong Song authored
    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.
