Hi, My name is Prudhvee and I'm purusing my undergraduate second year. I'm intrested in kernel development but I'm unable to understand how to get into it. Can you please help me to become a kernel developer. I just want to know what I should learn and any suggested books to learn kernel programming. Thank you, Prudhvee.

I would suggest get the foundations right first and let's hope you know good C, tricks are good to know but you should be able to understand code written by others and be able to integrate the knowledge with what you already know. If you haven't used semaphores or mutexes in user space code then do that first, understand why is the need. For example why you need to have a sycall to get a semaphore but when working with pthreads you probably don't need that. Understand compiler and make it your friend. Errors you get while compiling, and things you can do for example why ((struct mystruct*)(0))->member fails when you run code but &(((struct mystruct*)(0))->member) works. Basic idea is to get to understand how would you do it yourself, get some ideas in your mind see if they should work or not. You may be able to write code maybe without going through all that but in the long run it would help.

Take an operating system course first. Get to know the basics then you can try to understand kernel code. You can start with LDD, i think a new version is available now, but take an OS course in parallel or read yourself.
Thank you, Prudhvee.

Hello Prudhvee, I would suggest first start with Kernel Basic and O.S Concept to understand where Kernel really fits in O.;S and then gradually speed up to learn How Kernel works by referring interesting books like Kernel Development by Robert Love and also have source code handy to map the Kernel source code with Book to understand the functionality.I Bet you that once you done with Kernel Development by Robert Love then you can start working in community and then will let you know next step.

While on the subject of books, is Understanding the Linux Kernel - 3rd edition worth reading (it covers 2.6)? On 06/11/2014 02:28 AM, Prudhvee Narasimha Sadha wrote:

Learn C. Learn C *really* well. Especially the way the Linux kernel implements object-oriented concepts using callbacks through structures of function pointers (struct file_ops, etc...) Learn about race conditions and locking. Come to grips with the fact that the Linux kernel of 2014 isn't the kernel from 2004 - most of the code has already been looked over by lots of professional programmers, and a lot of the low-hanging fruit has been cleared out already. So be prepared to accept that these days, not everybody can be a productive kernel hacker. However, Greg KH is *always* willing to accept any coding love you want to give to anything in drivers/staging :) Two very helpful book, even though they are *not* about Linux: Maurice Bach - The Design of the Unix Operating System McKusick - The Design and Implementation of the FreeBSD Operating System Why? It's useful to understand different solutions for how to represent things like processes, files, and devices. And both books are an excellent way to learn about locking in the context of OS design, as they spend a *lot* of time on "We need to lock this data structure from this point in time until this other thing finishes, because otherwise something else could run here and do this other perfectly reasonable thing at just the wrong time, which would unfortunately end up turning your entire filesystem into a steaming pile of dingo kidneys because such-and-such will get trashed..." And if you're bored, Elliot Organick's "The Multics System: An Examination of its Structure" (ISBN 0-262-15012-3) has insights to be understood, 40 years after it came out....
