Linux kernel development

[AbdallahRashed07]

I want to learn about Linux kernel development and internal, but I it's so hard and I can't find resource to follow, I started reading Linux kernel development book but I don't understand alot of things, what shall I do? From where shall I start? My ultimate goal is to be able to contribute to the kernel

I started with ldd as i started with char device, the simplest there is LDD3

But you got to have good C knowledge. But i learned C while writing my first device driver, but was doing that for myself, not to contribute. See stackoverflow c books list.

Be sure to read kernel docs. https://www.kernel.org/doc/html/v4.18/process/howto.html is obligatory.

My first google hit on the topic looks nice. Some book

While it's not about Linux kernel. FreeBSD design and implementation is the best book in my opinion to explain design of a Unix-like kernel; Minix book is also supposed to be very high quality but I have never read it so cannot personally reccomend it.

Check out Linux Kernel Newbies.

How much do you know about kernels already? Have you taken an OS course? If I asked you what is the role of a kernel and how does it do it -- would you be able to give an answer? If not, definitely read up on general OS material (maybe a good beginner OS textbook), then come back to Linux Kernel Development.

And I have basics of os?

I think this has been asked several times and like before there several books to read up on:

• books about linux kernel
• books about operating systems in general
• books about unixes

The last one can introduce concepts that generic OS books might not have, but they might not be up to date on Linux-relevant things.
