Thanks !!
I looked at the code for top command again and I could see /proc/stat being
used. So I guess
that should be the best way to do it.

Hi,

Is there any other way to do this? If I need to write a kernel module

that

needs to get cpu utilization
should I still use proc/stat ? Is there a kernel function that can be

used

in a module ?

To get the information that's shown in /proc/stat, I'd suggest having a
look at fs/proc/stat.c in the kernel tree.
