Hello Sir/Mam

I am a total new fellow for Linux. I want to understand Kernel source code.., since i am from electronics background, I don't know about implementation of operating system, however i do know the principles/algorithms being used. If you can kindly clarify the following doubts it would be very helpful.

1. Is it mandatory to know Unix., before understanding Linux kernel source code.

2.Which is the best book to refer for understanding Linux kernel source code from scratch.


Thank you.

anup2314,

Not mandatory. Linux is another code trying to be "Unix-like" as possible owing to respectable reputation Unix gained through computing history. If you want to get familiar with Linux you can go directly into it. Since you are concerned with "kernel" programming it is best for you to get some books first that treat the basics of kernel, or go directly to how linux kernel is implemented. Download this pdf book for Linux kernel, or get its .doc format here. It is compressed in bz2 format, if you are using windows, rar app can extract it. If under linux you only enter this command on the terminal: user@host--$ tar xvjf name-of-archive.tar.bz2 <Enter>

Aside from that free downloadable book I have linked to you above you can choose from among these good books: click here.

Hope this helps.

Good luck.

I hope that you have a Linux distribution on your system.

Assuming that you may try these books:

Kernel Specific:
* Understanding the Linux Kernel - O'Reilly
* Linux Kernel Development - Robert Love , Novell Press

For more general discussions you may refer to:

* Operating System Principles - Galvin , Wiley Press


Minix is a Unix like Os , so you may consider starting with that. A very good reason to do so is:

* Operating system design and implementation - A. S. Tanenbaum

This book discusses the full source code of Minix Kernel.

My advice would be first get hands on with a linux machine, i mean learn the commands , shell etc and
then do some system programming(again there are some very boooks on that), and assembly language programming.
Then go for the kernel. I think you will be more comfortable that way.

The site for you is: http://kernelnewbies.org/

Note: Be sure to buy the book(edition) we discusses the kernel version of your interest.

Regards.
