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.
