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.

       -r --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.

       -n --no-rounding
	      Output frequencies and latencies without rounding off values.

       -c --perf
	      Get  performances	 and  frequencies  capabilities	 of CPPC, by reading it from hardware (only available on the
	      hardware with CPPC).

       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.
