OPTIONS -c --cpu <CPU> <CPU> number which information shall be determined about.

-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).

-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.

-h --help Prints out the help screen.
