Details |
We currently use the known constant values of the perf event config found here. The RAPL perf event config value for each domain (PKG, CORES, DRAM, etc) should be determined by the corresponding sysfs files. The event config value should be present in /sys/bus/event_source/devices/power/events/energy-<domain>. For example:
cat /sys/bus/event_source/devices/power/events/energy-pkg
event=0x02
