Hi
If I use the command line option "profile=2" while booting the system, why /proc/profile file is not created? Should I have to create it manually?
Thanking You' Shesha

Start with the file linux/Documentation/basic_profiling.txt (it's in Linux 2.5.66-or-so or later).
It explains how to use oprofile and readprofile.
You can read about oprofile at http://oprofile.sourceforge.net/ .
You can read about basic in-kernel profiling using /proc/profile and readprofile via 'man readprofile'. It's simple to use.
