Adding new working point - frequency in linux

Mohamad Ahmad 




Deciding what frequency within the CPUfreq policy should be used is achieved using "cpufreq governors".
Inside the CPUFreq we can find:







cpu0/cpufreq/
 .
 .
 ....affected_cpus
 ....cpuinfo_cur_freq
 ....cpuinfo_max_freq
 ....cpuinfo_min_freq
 ....scaling_available_frequencies //available frequencies
 ....scaling_available_governors //available governors
 ....scaling_cur_freq
 ....scaling_driver
 ....scaling_governor
 ....scaling_max_freq
 ....scaling_min_freq


scaling_available_frequencies shows all available frequencies for example:








cat scaling_available_frequencies
2997000 2664000 2331000 1998000


















How can I add more frequency values?


Can anyone please help me to add additional intermediate frequency values?


Is that can be done in Linux config (kernel compilation) or in the cpufreq driver?
