Subject[PATCH v2 0/4] perf tool: Skip invalid hybrid PMU
Date
On hybrid platform, such as Alderlake, if atom CPUs are offlined,
the kernel still exports the sysfs path '/sys/devices/cpu_atom/' for
'cpu_atom' pmu but the file '/sys/devices/cpu_atom/cpus' is empty,
which indicates this is an invalid pmu. So we need to check and skip
the invalid hybrid pmu.

Also we need to update some perf test cases for core-only system.

Jin Yao (4):
perf pmu: Skip invalid hybrid pmu
perf tests: Fix 'Parse event definition strings' on core-only system
perf tests: Fix 'Roundtrip evsel->name' on core-only system
perf tests: Fix 'Convert perf time to TSC' on core-only system

tools/perf/tests/parse-events.c | 16 ++++++++++------
tools/perf/tests/perf-time-to-tsc.c | 3 ++-
tools/perf/util/pmu.c | 9 ++++++++-
