Learning Linux Kernel

Learning Linux Kernel

[Kaushal Shriyan]

Hi

I have been working on Linux OS for the last 10 years and it has been very
exiting and challenging to learn new technologies based on Linux. I am
basically a Sys Admin for Linux with bash programming and configuring and
setting up Linux Server including network services like BIND DNS,Apache
etc...

Although i do not know C and ASM Language, I am very much eager to start
learning Linux Kernel Code and contribute to linux kernel codebase
sometimes down the line.
Please guide/suggest me.

Regards,

Kaushal

If you don't know C, you'll probably will want to start with a C tutorial. You can skip learning assembly languages for now, there is very little of it in the kernel sources and it varies a lot from processor to processor, but you'll need to understand C very well in order to really understand the kernel.

Please learn C first, that is essential.

Hello!

I think people appreciate your enthusiasm. I do think that knowing C
programming is a prerequisite. So you need to start with that.
For the theory, if you want to start learning how the kernel works, I
recommend the book Linux Kernel Development [1] by Robert Love.
Another thing I would give you is this video [2] to know how to submit
your first patch.

Hi

Just curious to know about total number of linux kernel developers in the
world who contribute to linux kernel codebase. Any wiki or webpage which
mentions about it?

Regards

Kaushal

These are a statistics page, not sure how accurate it is though:
http://www.remword.com/kps_result/

I think that the best place to look at this are the annual reports of
the Linux foundation:
https://www.linuxfoundation.org/sites/main/files/lf_linux_kernel_development_2010.pdf

The Linux Foundation has a report every year about this detailing this
type of information.  Also, lwn.net reports on this every kernel
release, see those articles for details.

Oh, and as a teaser, for the past year of releases, 2.6.36 - 3.1.0
(October 2010 to October 2011) there was 2889 different developers who
got patches accepted into the Linux kernel codebase.

Hi Kaushal

Goof to hear you want to be part of Linux Kernel, here is a good
article of How to participate on the Linux Community

http://www.linuxfoundation.org/content/how-participate-linux-community-0

Learn GIT (maybe you already know it )

http://git-scm.com/

Clone the mainstream Kernel by it self

http://kernel.org/

Check the code you will see that must of the code is in C

Now after you feel confident on C (recommended book = C Programming
Language Kernighan) you can start to run the latest Kernel on your
Linux machine, subscribe to an specific Mailing list of development
you want to follow, apply the RFC patches and check if it works ,
suggest new ideas or even work on the solution for existing bugs in
bugzila. Have fun :)

Check on the article for this good advice

Andrew Morton gives this advice for aspiring kernel developers

The #1 project for all kernel beginners should surely be "make sure
that the kernel runs perfectly at all times on all machines which you
can lay your hands on". Usually the way to do this is to work with
others on getting things fixed up (this can require persistence!) but
that's fine--it's a part of kernel development.

Hope it helps

Victor Rodriguez

Also you might want to check this video uploaded on Youtube.
Nice explanation on how exactly the Kernel Developers' community works, 
along with the statistics (old ones, though).

Hi Victor,

Thanks a lot for the encouragement. I am obliged and got motivated. You
said  "subscribe to an specific Mailing list of development
you want to follow, apply the RFC patches and check if it works ,suggest
new ideas or even work on the solution for existing bugs in
bugzilla"

Development of Kernel Mailing list -> http://www.tux.org/lkml/#s3-1 is this
correct ?
Not sure about RFC Patches and existing bugs in bugzilla. Please point me
to the relevant web page.

Regards

Kaushal,

There are different mailing lists for the different subsystems/parts of
the kernel. The MAINTAINERS file and scripts/get_maintainer.pl in the
source code list them.

RFC in this case means "request for comments"; these are just patches
that are not finalized/applied to the subsystem maintainers' git trees
yet. Bugzilla (http://bugzilla.kernel.org/) is currently not available.
