.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
|
