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

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