NAME¶

cpupower-powercap-info - Shows powercapping related kernel and hardware configurations

SYNOPSIS¶

cpupower powercap-info

DESCRIPTION¶

cpupower powercap-info shows kernel powercapping subsystem information. This needs hardware support and a loaded powercapping driver (at this time only intel_rapl driver exits) exporting hardware values userspace 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 cores.
