Linux Kernel Development: The Complete Hands-On Guide to Building, Debugging, and Mastering the Linux Operating System from Scratch
Master the Linux Kernel from the Inside Out — Through Real Code, Real Tools, and Real Engineering Practice
Modern computing runs on the Linux kernel. Whether you’re building embedded systems, writing device drivers, optimizing performance, contributing upstream, or preparing for a career in systems programming, understanding the kernel is one of the most valuable and respected skills in software engineering.
This book is your complete, practical, and deeply detailed guide to learning exactly how the Linux kernel works — and how to engineer with it effectively.
Linux Kernel Development takes you far beyond theory. Every chapter is built around real-world workflows, hands-on exercises, annotated code walkthroughs, debugging sessions, and official kernel engineering practices. You learn how the kernel schedules tasks, manages memory, handles interrupts, enforces security, drives hardware, orchestrates I/O, and exposes interfaces to user space. More importantly, you learn how to work with the kernel as an inspecting it, modifying it, optimizing it, breaking it, and fixing it.
You will build modules, trace system calls, write device drivers, add new system calls, troubleshoot crashes, optimize performance with eBPF, tune scheduling policies, isolate workloads, and design and debug your own kernel feature from scratch.
By the end, you won’t just understand the Linux kernel — you will be capable of engineering within it confidently.
What You Will Learn
How modern Linux kernels are structured, initialized, and extended
Low-level memory management, virtual memory, page tables, allocators, NUMA, and memory debugging
Scheduling internals, task lifecycle, preemption, real-time policies, and latency tracing
Concurrency tools such as spinlocks, RCU, atomics, and kernel synchronization patterns
Writing, loading, and debugging kernel modules safely
Developing character, block, and network drivers
Filesystems and the I/O VFS, inodes, buffers, journals, and modern filesystems like XFS, Btrfs, and bcachefs
Networking sockets, routing, packet processing, Netfilter, and in-kernel networking hooks
Kernel LSMs, SELinux, AppArmor, stack protection, and exploit mitigations
eBPF and XDP for high-performance observability and in-kernel programmability
Kernel profiling, crash analysis, ftrace, perf, BPF tools, and performance optimization
CI/CD automation for kernel builds, DKMS workflows, and upstream patch submission
Future directions of Linux kernel Rust adoption, AI-assisted tuning, and next-generation observability
