NAME

6       cpupower-frequency-set  -  A  small tool which allows to modify cpufreq
7       settings.
8

SYNTAX

10       cpupower [ -c cpu ] frequency-set [options]
11

DESCRIPTION

13       cpupower frequency-set allows you to modify  cpufreq  settings  without
14       having   to   type   e.g.   "/sys/devices/system/cpu/cpu0/cpufreq/scal‐
15       ing_set_speed" all the time.
16

OPTIONS

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

35       REMARKS
36
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.
