NAME

6       cpufreq-set - A small tool which allows to modify cpufreq settings.
7

SYNTAX

9       cpufreq-set [options]
10

DESCRIPTION

12       cpufreq-set  allows  you  to  modify cpufreq settings without having to
13       type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed"  all
14       the time.
15

OPTIONS

17       -d --min <FREQ>
18              new minimum CPU frequency the governor may select.
19
20       -u --max <FREQ>
21              new maximum CPU frequency the governor may select.
22
23       -g --governor <GOV>
24              new cpufreq governor.
25
26       -f --freq <FREQ>
27              specific  frequency to be set. Requires userspace governor to be
28              available and loaded.
29
30       -r --related
31              modify all hardware-related CPUs at the same time
32
33       -h --help
34              Prints out the help screen.
35

REMARKS

37       By default values are applied on all cores. How to modify  single  core
38       configurations  is  described  in  the cpupower(1) manpage in the --cpu
39       option section.
40
41       The -f FREQ, --freq FREQ parameter cannot be combined  with  any  other
42       parameter.
43
44       FREQuencies  can  be  passed  in Hz, kHz (default), MHz, GHz, or THz by
45       postfixing the value with the wanted unit name, without any space (fre‐
46       quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).
47
48       On  Linux  kernels  up  to  2.6.29,  the  -r  or --related parameter is
49       ignored.
