Venkat,

You can use?http://lxr.linux.no/?to browse for kernel source. It's an online tool and you can directly see the usage, declaration, definition of functions, structures, etc.

how to understand the kernerl source? files in a simple way


what header? files i have to understand first


for example? to understand????? do_fork()???? function? for process
creation? which is defined in? kernel/fork.c

In the end the Linux kernel is just a big project written in C.
Instead of asking what files do you need to understand. You should ask
yourself what subsystem do you want to learn?

Focus on functionality and browse the code to understand. As others
pointed before there are lots of good books that will give you a high
overview of the kernel.

The first book that I recommend reading is Linux kernel development by
Robert Love, but only if you have already read a book on operating
system concepts. The best book for me is Andrew Tanenbaum's Modern
Operating Systems.

Hope it helps,
