Subject: [PATCH v2 0/2] perf tools: Add PMU alias support
Date: Thu, 29 Jul 2021 15:06:17 +0800 [thread overview]
Message-ID: <20210729070619.20726-1-yao.jin@linux.intel.com> (raw)
A perf uncore PMU may have two PMU names, a real name and an alias name.
With this patch set, the perf tool can monitor the PMU with either the
real name or the alias.
Use the real name,
$ perf stat -e uncore_cha_2/event=1/ -x,
4044879584,,uncore_cha_2/event=1/,2528059205,100.00,,
Use the alias,
$ perf stat -e uncore_type_0_2/event=1/ -x,
3659675336,,uncore_type_0_2/event=1/,2287306455,100.00,,
v2:
---
Add test case to verify the real name and alias name having same effect.
