Subject: [PATCH v3 15/27] perf stat: Filter out unmatched aggregation for hybrid event
Date: Mon, 29 Mar 2021 15:00:34 +0800 [thread overview]
Message-ID: <20210329070046.8815-16-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210329070046.8815-1-yao.jin@linux.intel.com>
perf-stat has supported some aggregation modes, such as --per-core,
--per-socket and etc. While for hybrid event, it may only available
on part of cpus. So for --per-core, we need to filter out the
unavailable cores, for --per-socket, filter out the unavailable
sockets, and so on.
Before:
# perf stat --per-core -e cpu_core/cycles/ -a -- sleep 1
Performance counter stats for 'system wide':
S0-D0-C0 2 479,530 cpu_core/cycles/
S0-D0-C4 2 175,007 cpu_core/cycles/
S0-D0-C8 2 166,240 cpu_core/cycles/

S0-D0-C38 0 <not counted> cpu_core/cycles/
S0-D0-C39 0 <not counted> cpu_core/cycles/

After:
# perf stat --per-core -e cpu_core/cycles/ -a -- sleep 1
Performance counter stats for 'system wide':
S0-D0-C0 2 210,428 cpu_core/cycles/
