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

SYNTAX cpufreq-set [options]

DESCRIPTION cpufreq-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.

OPTIONS -c --cpu <CPU> number of CPU where cpufreq settings shall be modified.

-d --min <FREQ> new minimum CPU frequency the governor may select.

-u --max <FREQ> new maximum CPU frequency the governor may select.

-g --governor <GOV> new cpufreq governor.

-f --freq <FREQ> specific frequency to be set. Requires userspace governor to be available and loaded.

-r --related modify all hardware-related CPUs at the same time

-h --help Prints out the help screen.

REMARKS Omitting the -c or --cpu argument is equivalent to setting it to zero.

The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter except the -c CPU, --cpu CPU parameter.

FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre- quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).

On Linux kernels up to 2.6.29, the -r or --related parameter is ignored.
