perf report: Group stat values on global event id
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 Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20170824162737.7813-10-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
