cpupower powercap-info
DESCRIPTION
cpupower powercap-info shows kernel powercapping subsystem informa-

this time only intel_rapl driver exits) exporting hardware values user-
space via sysfs.
Some options are platform wide, some affect single cores. By default
values of core zero are displayed only. cpupower --cpu all cpuinfo will
show the settings of all cores, see cpupower(1) how to choose specific
