If you want to write code that talks to hardware (USB, PCI, etc.), this is the definitive guide.
The third edition was written specifically for the 2.6 kernel and includes extensive new material on the Linux device model, USB bus support, the serial driver subsystem, and enhancements to the PCI layer. The finished PDF files are available for free download, and the authors have made them accessible to the community. You can find this PDF hosted across various educational mirrors and GitHub repositories dedicated to collecting technical literature.
Every component—from hardware drivers to file systems—shares the same privileged memory space. A single unhandled pointer error can trigger a kernel panic and crash the entire system. linux kernel programming pdf github full
Once you have mastered the basic hello-world module, push your boundaries by implementing these intermediate projects:
, Linux Kernel Programming Part 2 - Char Device Drivers and Kernel Synchronization , serves as an ideal companion guide. It focuses specifically on creating user-kernel interfaces, working with peripheral I/O, and handling hardware interrupts. The code repository for this book is available on GitHub at https://github.com/PacktPublishing/Linux-Kernel-Programming-Part-2 , providing actual project code for writing misc class character device drivers on the 5.4 LTS kernel.

In addition to the books mentioned above, GitHub hosts several community-driven collections of kernel materials that are invaluable for self-study:
Searching GitHub for curated lists (often titled awesome-linux-kernel ) will lead you to crowdsourced repositories containing: You can find this PDF hosted across various
