[PATCH v3 0/2] perf tools: Add PMU alias support
From: Jin Yao
Date: Fri Jul 30 2021 - 03:08:49 EST
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,,
v3:
---
1. Use fgets() to replace fscanf().
2. Resource cleanup.
v2:
---
Add test case to verify the real name and alias name having same effect.
