запустите команду и запишите ее профиль в perf.data (Run a command and record its profile into perf.data)
PERF-STAT:
If there is no -e specified in perf stat, on hybrid platform,
besides of software events, following events are created and
added to event list in order.
cpu_core/cycles/, cpu_atom/cycles/, cpu_core/instructions/,
cpu_atom/instructions/, cpu_core/branches/, cpu_atom/branches/,
cpu_core/branch-misses/, cpu_atom/branch-misses/
Of course, both perf-stat and perf-record support to enable
hybrid event with a specific pmu.
e.g. perf stat -e cpu_core/cycles/ perf stat -e cpu_atom/cycles/
perf stat -e cpu_core/r1a/ perf stat -e cpu_atom/L1-icache-loads/
perf stat -e cpu_core/cycles/,cpu_atom/instructions/ perf stat -e
{cpu_core/cycles/,cpu_core/instructions/}
But {cpu_core/cycles/,cpu_atom/instructions/} will return warning
and disable grouping, because the pmus in group are not matched
(cpu_core vs. cpu_atom).
