    perf report: Group stat values on global event id · 9933183e
    Jiri Olsa authored
    There's no big value on displaying counts for every event ID, which is
    one per every CPU. Rather than that, displaying the whole sum for the
    event.
    
      $ perf record -c 100000 -e cycles:u -s test
      $ perf report -T
    
    Before:
      #  PID   TID  cycles:u  cycles:u  cycles:u  cycles:u  ... [20 more columns of 'cycles:u']
        3339  3339         0         0         0         0
        3340  3340         0         0         0         0
        3341  3341         0         0         0         0
        3342  3342         0         0         0         0
    
    Now:
      #  PID   TID  cycles:u
        3339  3339     19678
        3340  3340     18744
        3341  3341     17335
        3342  3342     26414
