Linux distribution (or distro): Ubuntu 22.04 LTS (‘Jammy Jellyfish’) free security and maintenance updates guaranteed until April 2027, EOL is April 2032 Linux kernel version: 5.10.y LTS (longterm) End Of Life (EOL) is December 2026 Very briefly, for the purpose of this book, here’s what we’ll select:
LINUX KERNEL PROGRAMMING INSTALL
It's key that you install a recent and well supported Linux distribution, along with a (custom-built) recent long-term Linux kernel. You can clone and work on it by cloning the git tree, like so:Īs discussed previously, a practical and convenient alternative to using a native Linux system is to install and use the Linux distribution as a guest OS on a VM. Of course, the downside is performance – working on a high spec native Linux box can be up to twice as fast when compared to working on a VM!Ĭloning our code repository: The complete source code for this book is freely available on GitHub at. Working within a guest VM also adds an additional layer of isolation and thus safety. So, we shall assume that you are working on a Linux guest. However, for the purposes of this book, we cannot assume that you will always have a dedicated native Linux box available to you. Like any seasoned kernel developer, I would say that working on a native Linux system is best. It should be pretty obvious – the more RAM, CPU power and disk space the host system has, the better! This is as performing tasks such as building a Linux kernel from source is a very memory- and CPU-intensive process. I’d suggest you go with a system well beyond the minimum recommendation, as powerful a system as you can afford to use. Ubuntu Desktop specifies "recommended minimum system requirements" for the installation and usage of the distribution here. You will need a modern – and preferably powerful - desktop PC or laptop. This chapter will take you through the following topics, which will help set up your working environment:
LINUX KERNEL PROGRAMMING DRIVER
Hence, this book gives you many hands-on experiments and kernel code examples that you can and indeed must try out yourself this will greatly aid in your making real progress, learning deeply and understanding various aspects of Linux kernel and driver development. So, remember: Right at the outset, something I like to emphasize, is this: the best way to learn something is to do so empirically – not taking anyone's word on anything at all, but trying it out and experiencing it for yourself.
We will also clone this book's code repository on GitHub, and learn about a few useful projects that will help along this journey.
LINUX KERNEL PROGRAMMING SOFTWARE
We will install a recent Linux distribution, preferably as a Virtual Machine ( VM), and set it up to include all the required software packages.
LINUX KERNEL PROGRAMMING HOW TO
This chapter will teach you exactly how to do this and get started. To get the most out of this book, it is very important that you first set up the workspace environment that we will be using throughout the book. Hello, and welcome to this book on learning Linux kernel programming. You’ll understand the deep issues of concurrency, and gain insight into how they can be addressed with various locking technologies (mutexes, spinlocks, atomic / refcount operators and even lock-free technologies).īy the end of this 2nd Edition book, you’ll have a better understanding of the fundamentals of writing Linux kernel and kernel module code that can be used in real-world projects and products. You’ll then get to delve into key kernel internals topics including Linux kernel architecture, memory management, and CPU scheduling. You’ll then learn, step by step, how to write your first kernel module by leveraging the kernel’s powerful Loadable Kernel Module (LKM) framework. In this new edition, you’ll start the journey by learning how to build the kernel from source, including doing a kernel build for the popular Raspberry Pi. This book uses the recent 5.10 Long-Term Support (LTS) Linux kernel series, which will be maintained until 2026, showing 5.X/6.X new features. The 2nd Edition of Linux Kernel Programming is an updated, comprehensive introduction for new programmers to the Linux kernel.
