Linux Kernel Programming Part 2 - Char Device Drivers and Kernel Synchronization: Create user-kernel interfaces, work with peripheral I/O, and handle hardware interrupts Paperback – 19 March 2021

Glad to read this book. I recommand this book. I continue to read it to learn more things. He is great trainer and author too. I always recommend to read his books and blogs.

the interesting part I like in this book is that the author has made it self-contained and the words used are easy to understand. this book has used the latest kernel release which gave a good understanding of both the concepts and source code, the author also pointed some good websites where you can start your contribution and the challenges conducted by the Linux Foundation. Some other book is also available which gives a good understanding of the concepts about Linux kernel but those books are written during kernel 2.6 release and the source code are outdated which is really a headache when you want to understand both the high-level concepts and the source code written
