What kind of profiling do you want to do?

Anil Kumar :

after booting system, I am loading my network device
driver module in linux kernel .

I wanna to know how much time is taking by functions
of my module at any time (i.e just after loading
module or just after sending or receiving data etc).
So I  can improve performance of my module by
improving those function which taking maximum time or 
cpu utilization.

Check out oprofile:
in kernel tree, Documentation/basic_profiling.txt (2.6.x)

Basic in-kernel profiling (older version, before oprofile)
does not work with loadable modules, just with in-kernel code.
You could use this if you build your driver in-kernel.

There are also some performance-counter patches, but
I don't know how to use them [if your h/w supports them].

MOTD:  Always include version info.
(Again.  Sometimes I think ln -s /usr/src/linux/.config .signature)
