Subject: [PATCH 46/49] perf stat: Filter out unmatched aggregation for hybrid event
Date: Mon, 8 Feb 2021 07:25:43 -0800 [thread overview]
Message-ID: <1612797946-18784-47-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1612797946-18784-1-git-send-email-kan.liang@linux.intel.com>
From: Jin Yao <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:
root@otcpl-adl-s-2:~# ./perf stat --per-core -e cpu_core/cycles/ -a -- sleep 1
Performance counter stats for 'system wide':
S0-D0-C0 2 311,114 cycles [cpu_core]

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

After:
