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. FILES
