cpufreq−info − Utility to retrieve cpufreq kernel information
cpufreq−info [options]
A small tool which prints out cpufreq information helpful to developers and interested users.
−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).
−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.
−h −−help
Prints out the help screen.
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.
