Overview of this book

Mastering Linux Kernel Development looks at the Linux kernel, its internal arrangement and design, and various core subsystems, helping you to gain significant understanding of this open source marvel. You will look at how the Linux kernel, which possesses a kind of collective intelligence thanks to its scores of contributors, remains so elegant owing to its great design. This book also looks at all the key kernel code, core data structures, functions, and macros, giving you a comprehensive foundation of the implementation details of the kernel’s core services and mechanisms. You will also look at the Linux kernel as well-designed software, which gives us insights into software design in general that are easily scalable yet fundamentally strong and safe. By the end of this book, you will have considerable understanding of and appreciation for the Linux kernel.

Summary


We understood one of the principal abstractions of Linux called the process, and the whole ecosystem that facilitates this abstraction. The challenge now remains in running the scores of processes by providing fair CPU time. With many-core systems imposing a multitude of processes with diverse policies and priorities, the need for deterministic scheduling is paramount.

In our next chapter, we will delve into process scheduling, another critical aspect of process management, and comprehend how the Linux scheduler is designed to handle this diversity.
