Linux Kernel Programming in Practice: Build Kernel Modules, Device Drivers, and Debugging Skills to Write Safer, More Reliable Low-Level Linux Code

Linux Kernel Programming in Practice: Build Kernel Modules, Device Drivers, and Debugging Skills to Write Safer, More Reliable Low-Level Linux Code Stop treating Linux kernel programming like unreachable expert territory. Build real low-level Linux skill through safe, practical, hands-on work.

Do you know C, use Linux, and want to understand what happens below ordinary application code? Are kernel modules, device drivers, memory rules, locking, and debugging workflows still difficult to connect in a practical way?

Linux Kernel Programming in Practice gives you a structured path into kernel-level development without burying you in theory first. You’ll set up a safe Linux lab, build loadable kernel modules, work with module parameters, write character device drivers, manage kernel memory, handle synchronization, expose procfs and sysfs interfaces, use timers and workqueues, and test your code with a disciplined debugging workflow.

Inside, you’ll learn how to:

Build and load kernel modules safely
Use kbuild, insmod, rmmod, lsmod, modinfo, and dmesg
Write practical character device drivers
Move data safely between user space and kernel space
Handle memory allocation, cleanup paths, and failure cases
Protect shared state with kernel synchronization tools
Debug with logs, dynamic debug, ftrace, trace-cmd, and kernel tools
Complete final projects that reinforce real driver-development habits

What makes this book different is its workshop-style approach: complete commands, Makefiles, test workflows, reusable patterns, final projects, and checklists are included directly in the book, so you are not dependent on a separate repository.

This book is for C programmers, Linux users, embedded developers, systems programmers, cybersecurity learners, computer science students, and engineers who want practical low-level Linux development skills.
