| .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. |
