       cpupower frequency-info - Utility to retrieve cpufreq kernel information


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


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


       -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.


       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

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