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