perf report: Fix and improve the displaying of per-thread event counters
Improve and fix the handling of per-thread counter stats recorded via perf record -s. Previously we only displayed it in debug printouts (-D) and even that output was hard to disambiguate. I moved everything to utils/values.[ch] so that we may reuse it in perf stat. We get something like this now: # PID TID cache-misses cache-references 4658 4659 495581 3238779 4658 4662 498246 3236823 4658 4663 499531 3243162 Then it'll be easy to add --pretty=raw to display a single line per thread/event. By the way, -S was also used for --symbol... So I used -T/--thread here. perf report: Add -T/--threads to display per-thread counter values We get something like this now: # PID TID cache-misses cache-references 4658 4659 495581 3238779 4658 4662 498246 3236823 4658 4663 499531 3243162 Per-thread arrays of counter values are managed in utils/values.[ch] Signed-off-by: Brice Goglin <Brice.Goglin@inria.fr> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: paulus@samba.org Signed-off-by: Ingo Molnar <mingo@elte.hu>
