CPUPOWER-FREQUENCY-INFO(1)					  cpupower Manual					CPUPOWER-FREQUENCY-INFO(1)

NAME

       cpupower frequency-info - Utility to retrieve cpufreq kernel information

SYNTAX

       cpupower [ -c cpulist ] frequency-info [options]

DESCRIPTION

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

OPTIONS

       -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.

       REMARKS

       By  default  only  values of core zero are displayed. How to display settings of other cores is described in the cpupower(1) manpage in the
       --cpu option section.

       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.
