cpufreq−set − A small tool which allows to modify cpufreq settings.
cpufreq−set [options]
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.
−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.
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 =ˆ Hz * 0.001 =ˆ MHz * 1000 =ˆ GHz * 1000000).
On Linux kernels up to 2.6.29, the −r or −−related parameter is ignored.
