perf report: Add raw displaying of per-thread counters
If --pretty=raw is given to perf report -T, it now displays one line per-thread per-counter with the raw event id added. We get: # PID TID Name Raw Count 18608 18609 cache-misses 28e 416744 18608 18609 cache-references 28f 6456792 18608 18608 cache-misses 28e 448219 18608 18608 cache-references 28f 7270244 instead of: # PID TID cache-misses cache-references 18608 18609 416744 6456792 18608 18608 448219 7270244 Signed-off-by: Brice Goglin <Brice.Goglin@inria.fr> Acked-by: Peter Zijlstra <peterz@infradead.org> LKML-Reference: <4A802008.5050409@inria.fr> Signed-off-by: Ingo Molnar <mingo@elte.hu>
