Shows powercapping related kernel and hardware configurations

## 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)](/cpupower/1.md) how to choose specific cores.**
