From 886c3b2d677fe248cce8101fa66a1b3e05c3ba16 Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Tue, 22 Jan 2013 22:25:29 -0800 Subject: perf/POWER7: Make some POWER7 events available in sysfs Make some POWER7-specific perf events available in sysfs. $ /bin/ls -1 /sys/bus/event_source/devices/cpu/events/ branch-instructions branch-misses cache-misses cache-references cpu-cycles instructions PM_BRU_FIN PM_BRU_MPRED PM_CMPLU_STALL PM_CYC PM_GCT_NOSLOT_CYC PM_INST_CMPL PM_LD_MISS_L1 PM_LD_REF_L1 stalled-cycles-backend stalled-cycles-frontend where the 'PM_*' events are POWER specific and the others are the generic events. This will enable users to specify these events with their symbolic names rather than with their raw code. perf stat -e 'cpu/PM_CYC' ...
