[PATCH v5 0/2] perf tools: Add PMU alias support

From: Jin Yao <hidden>
Date: 2021-08-17 05:21:15
Also in: lkml

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,,

v5:
---
1. Don't use strdup in find functions (pmu_find_real_name and
   pmu_find_alias_name). Just return name and keep the
   'pmu->name = strdup(name);' in pmu_lookup.

2. Remove invalid comment for alias_name in struct perf_pmu.

v4:
---
1. Fix memory leaks in pmu_lookup.
2. Rebase to perf/core.

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.
