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

REMARKS

40       Omitting the -c or --cpu argument is equivalent to setting it to zero.
41
42       The -f FREQ, --freq FREQ parameter cannot be combined  with  any  other
43       parameter except the -c CPU, --cpu CPU parameter.
44
45       FREQuencies  can  be  passed  in Hz, kHz (default), MHz, GHz, or THz by
46       postfixing the value with the wanted unit name, without any space (fre‐
47       quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).
48
49       On  Linux  kernels  up  to  2.6.29,  the  -r  or --related parameter is
50       ignored.
