[PATCH 28/49] perf pmu: Save detected hybrid pmus to a global pmu list

From: Jin Yao We identify the cpu_core pmu and cpu_atom pmu by explicitly checking following files: For cpu_core, check: "/sys/bus/event_source/devices/cpu_core/cpus" For cpu_atom, check: "/sys/bus/event_source/devices/cpu_atom/cpus" If the 'cpus' file exists, the pmu exists. But in order not
