NAME
       cpupower  frequency-info  - Utility to retrieve cpufreq kernel informa-
       tion
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 inter-
              face 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.

       REMARKS
       By  default only values of core zero are displayed. How to display set-
       tings 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.
