cpufreq-set

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 (frequency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).

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