| .SH "NAME" |
| .LP |
| cpupower frequency\-set \- A small tool which allows to modify cpufreq settings. |
| .SH "SYNTAX" |
| .LP |
| cpupower [ \-c cpu ] frequency\-set [\fIoptions\fP] |
| .SH "DESCRIPTION" |
| .LP |
| cpupower frequency\-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all the time. |
| .SH "OPTIONS" |
| .LP |
| .TP |
| \fB\-d\fR \fB\-\-min\fR <FREQ> |
| new minimum CPU frequency the governor may select. |
| .TP |
| \fB\-u\fR \fB\-\-max\fR <FREQ> |
| new maximum CPU frequency the governor may select. |
| .TP |
| \fB\-g\fR \fB\-\-governor\fR <GOV> |
| new cpufreq governor. |
| .TP |
| \fB\-f\fR \fB\-\-freq\fR <FREQ> |
| specific frequency to be set. Requires userspace governor to be available and loaded. |
| .TP |
| \fB\-r\fR \fB\-\-related\fR |
| modify all hardware-related CPUs at the same time |
| .TP |
| .SH "REMARKS" |
| .LP |
| 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. |
| .LP |
| 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. |
