.TH CPUPOWER\-POWERCAP\-INFO "1" "05/08/2016" "" "cpupower Manual" .SH NAME cpupower\-powercap\-info \- Shows powercapping related kernel and hardware configurations .SH SYNOPSIS .ft B .B cpupower powercap-info .SH DESCRIPTION \fBcpupower powercap-info \fP 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. .SH "DOCUMENTATION" kernel sources: Documentation/power/powercap/powercap.rst .SH "SEE ALSO" cpupower(1)
