Was the OP asking about methodology to understand the kernel code? In that case, I can see at least 2 options: top-down and bottom-up reading/studying. Top-down could mean you start with main() and work your way down to a specific sub-system or driver or function. Bottom-up could be that you start with a driver's function and work your way up to some main/central point. There are probably other ways to do it. Things you might want to find out: 1) Where are function / macro is defined. 2) Does it call functions outside its file 3) What the callers are (which functions call the function you are looking at) 4) Which functions does this function call? Either way, it will require a lot of time and patience, and reading of the source code and other books. The cscope / ctags programs could also help.
