Hi Milad,

the following helped me a lot while learning the basic kernel concepts:

- Linux Device Drivers, 3rd Edition book (LDD3)
- Linux Kernel Development, 3rd edition book (LDK)
- Linux Kernel Labs: https://linux-kernel-labs.github.io/master/
- MIT OS Course Labs: https://pdos.csail.mit.edu/6.828/2018/index.html

I suggest you start with the LDD3 book which although a bit old, it's
easier and more focused than the LKD book. You can then proceed with the
LKD book which covers more parts of the kernel in a higher level style.

To complement your study of concepts from the book you should follow the
Linux kernel labs. They are a great way to experiment and have a bit of fun.

The last resource is optional but imho it helps a lot to take a good course
on OS design and implementation while studying the Linux kernel, even if
you have previously took one (i.e from your university). The MIT course has
great labs that will force you to dive deep into not so easy concepts like
memory management, page tables etc. that are the core of a kernel. They are
also based on XV6, a very small kernel that you can fully understand in a
reasonable time (Linux is no such case).

Have fun!

Elias
