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.
