perf/x86/rapl: Add core energy counter support for AMD CPUs
Add a new "power_core" PMU and "energy-core" event for monitoring
energy consumption by each individual core. The existing energy-cores
event aggregates the energy consumption of CPU cores at the package level.
This new event aligns with the AMD's per-core energy counters.
Tested the package level and core level PMU counters with workloads
pinned to different CPUs.
Results with workload pinned to CPU 4 in core 4 on an AMD Zen4 Genoa
machine:
$ sudo perf stat --per-core -e power_core/energy-core/ -- taskset -c 4 stress-ng --matrix 1 --timeout 5s
stress-ng: info: [21250] setting to a 5 second run per stressor
stress-ng: info: [21250] dispatching hogs: 1 matrix
stress-ng: info: [21250] successful run completed in 5.00s
Performance counter stats for 'system wide':
S0-D0-C0 1 0.00 Joules power_core/energy-core/
S0-D0-C1 1 0.00 Joules power_core/energy-core/
S0-D0-C2 1 0.00 Joules power_core/energy-core/
S0-D0-C3 1 0.00 Joules power_core/energy-core/
