|

|

By default values are applied on all cores. How to modify single core

configurations is described in the cpupower(1) manpage in the \-\-cpu option section.

The \-f FREQ, \-\-freq FREQ parameter cannot be combined with any other parameter.
|
||
|
|
.LP
|
||
|
|
FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (frequency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).
|

|
|
.LP
|
||
|
|
On Linux kernels up to 2.6.29, the \-r or \-\-related parameter is ignored.
