regarding processor core frequency changes

[kumar D]

can anyone please suggest me that where we can change frequency levels of the core in kernel code.

like in DVFS(dynamic voltage frequency scaling ) we are setting for different frequencies different voltages.

thanks in advance :)

i guess, u can change in kernel .config file...CONFIG_HZ...and try to grep this config in kernel code, u may find appropriate code..its nt difficult..

CONFIG_HZ is not the cpu core frequency.  That is the timer interrupt frequency.

Why not try the system file node like "scaling_cur_freq"  "scaling_max_freq" "scaling_min_freq" bla bla...
