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.

NAME

       cpufreq-info - Utility to retrieve cpufreq kernel information

SYNTAX

       cpufreq-info [options]

DESCRIPTION

       A small tool which prints out cpufreq information helpful to developers and interested users.

OPTIONS

       -c --cpu <CPU>
	       <CPU> number which information shall be determined about.

       -e --debug
	      Prints out debug information.

       -f --freq
	      Get frequency the CPU currently runs at, according to the cpufreq core.

       -w --hwfreq
	      Get frequency the CPU currently runs at, by reading it from hardware (only available to root).

       -l --hwlimits
	      Determine the minimum and maximum CPU frequency allowed.

       -d --driver
	      Determines the used cpufreq kernel driver.

       -p --policy
	      Gets the currently used cpufreq policy.

       -g --governors
	      Determines available cpufreq governors.

       -a --related-cpus
	      Determines which CPUs run at the same hardware frequency.

       -a --affected-cpus
	      Determines which CPUs need to have their frequency coordinated by software.

       -s --stats
	      Shows cpufreq statistics if available.

       -y --latency
	      Determines the maximum latency on CPU frequency changes.

       -o --proc
	      Prints out information like provided by the /proc/cpufreq interface in 2.4. and early 2.6. kernels.

       -m --human
	      human-readable output for the -f, -w, -s and -y parameters.

       -h --help
	      Prints out the help screen.

REMARKS

       You can't specify more than one of the output specific options -o -e -a -g -p -d -l -w -f -y.

       You also can't specify the -o option combined with the -c option.
