cpufreq-info - Utility to retrieve cpufreq kernel information
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.
