Currently the energy-cores event in the power PMU aggregates energy
consumption data at a package level. On the other hand the core energy
RAPL counter in AMD CPUs has a core scope (which means the energy
consumption is recorded separately for each core). Earlier efforts to add
the core event in the power PMU had failed [1], due to the difference in
the scope of these two events. Hence, there is a need for a new core scope
PMU.
This patchset adds a new "power_per_core" PMU alongside the existing
"power" PMU, which will be responsible for collecting the new
"energy-per-core" event.
Tested the package level and core level PMU counters with workloads
pinned to different CPUs.
Results with workload pinned to CPU 1 in Core 1 on an AMD Zen4 Genoa
machine:
$ perf stat -a --per-core -e power_per_core/energy-per-core/ -- sleep 1

v5 changes:
* Rebase on top of Kan Liang's "PMU scope" patchset [2]
* rapl_cntr_mask moved to rapl_pmus struct in patch 8
* Patch 1 from v4 is merged separately, so removed from this series
* Add an extra argument "scope" in patch 5 to the init functions
* Add an new patch 2, which removes the cpu_to_rapl_pmu() function
Base: tip/perf/core(currently has just 1-5 patches from [2]) + patch 6 from [2] +
diff [3] + patch 7 from [2] + revert [4] + apply [5]
