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.
