Subject: [PATCH v6 07/26] perf stat: Uniquify hybrid event name
Date: Tue, 27 Apr 2021 15:01:20 +0800 [thread overview]
Message-ID: <20210427070139.25256-8-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210427070139.25256-1-yao.jin@linux.intel.com>
It would be useful to let user know 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, such as:
"cycles [cpu_core]"
Now this option is enabled by default for hybrid platform but change
the format to:
"cpu_core/cycles/"
If user configs the name, we still use the user specified name.
Signed-off-by: Jin Yao <yao.jin@linux.intel.com>

v6:
- Rebase to tmp.perf/core branch.
v5:
- Move 'evsel->use_config_name = true;' from
'[PATCH v5 12/26] perf parse-events: Support event inside hybrid pmu'
to the patch.
v4:
- If user configs the name, we still use the user specified name.
v3:
- No change.
