Linux Kernel Development and Internals

Understanding the heart of the operating system is essential for anyone looking to master low-level systems programming and high-performance computing. This course provides a clear path into the complex world of the Linux kernel, enabling you to understand how hardware and software interact at the most fundamental level. You will transition from a user-space developer to someone who understands process management, memory allocation, and hardware communication. By reading through detailed explanations and analyzing code examples, you will gain the confidence to navigate the kernel source tree and contribute to system-level projects. What you'll learn: - Understand the fundamental architecture and subsystems of the Linux kernel - Practice writing, compiling, and loading custom kernel modules - Apply core concepts of process scheduling and memory management - Implement basic device drivers to interact with system hardware - Explore modern kernel features including eBPF for system observability - Understand the emerging role of memory-safe languages like Rust in kernel development The course begins with essential terminology and environment setup before moving into deep dives of the VFS, interrupt handling, and synchronization primitives. It concludes with an introduction to modern tools and safety standards used in contemporary kernel engineering. This course is designed for programmers and students who are new to kernel development and want a structured, text-based approach to learning system internals.
