| |
From: Jin Yao <yao.jin@linux.intel.com>
It would be useful to tell user the pmu which the event belongs to. perf-stat has supported '--no-merge' option and it can print the pmu name after the event name.
Now this option is enabled by default for hybrid platform.
Before:
root@otcpl-adl-s-2:~# ./perf stat -e cycles -a -- sleep 1
Performance counter stats for 'system wide':
10,301,466 cycles 1,557,794 cycles
1.002068584 seconds time elapsed
After:
root@otcpl-adl-s-2:~# ./perf stat -e cycles -a -- sleep 1
Performance counter stats for 'system wide':
11,190,657 cycles [cpu_core] 669,063 cycles [cpu_atom]
1.002147571 seconds time elapsed
