sorry for the last mail that i was not able to convey what i was meaning to, i have noticed for almost all ARCH when i will do $ cat /proc/cpuinfo ,it will shows all cpu related info including cpu frequency but for my case i am getting almost everything except cpu frequency in /proc/cpuinfo.
Now my question is how i can add this cpufreq related info into /proc/cpuinfo ??

Also what all other alternatives /methods are there to get cpufreq related info from kernel ??

I am sorry, but I can not parse this very well, can you please explain
exactly what you wish to do and why the "normal" apis that expose the
current frequency of the processor do not work for you?  (hint, it's not

Also, who is demanding this requirement?
