- .TH "CPUPOWER\-FREQUENCY\-SET" "1" "0.1" "" "cpupower Manual"
- .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.
- .SH "FILES"
