Learn how to write high-quality kernel module code, solve common Linux kernel programming issues, and understand the fundamentals of Linux kernel internals
Key Features
Discover how to write kernel code using the Loadable Kernel Module framework
Explore industry-grade techniques to perform efficient memory allocation and data synchronization within the kernel
Understand the essentials of key internals topics such as kernel architecture, memory management, CPU scheduling, and kernel synchronization
Book Description
Linux Kernel Programming is a comprehensive introduction for those new to Linux kernel and module development. This easy-to-follow guide will have you up and running with writing kernel code in next-to-no time. This book uses the latest 5.4 Long-Term Support (LTS) Linux kernel, which will be maintained from November 2019 through to December 2025. By working with the 5.4 LTS kernel throughout the book, you can be confident that your knowledge will continue to be valid for years to come.
This Linux book begins by showing you how to build the kernel from the source. Next, you'll learn how to write your first kernel module using the powerful Loadable Kernel Module (LKM) framework. The book then covers key kernel internals topics including Linux kernel architecture, memory management, and CPU scheduling. Next, you'll delve into the fairly complex topic of concurrency within the kernel, understand the issues it can cause, and learn how they can be addressed with various locking technologies (mutexes, spinlocks, atomic, and refcount operators). You'll also benefit from more advanced material on cache effects, a primer on lock-free techniques within the kernel, deadlock avoidance (with lockdep), and kernel lock debugging techniques.
By the end of this kernel book, you'll have a detailed understanding of the fundamentals of writing Linux kernel module code for real-world projects and products.
What You Will Learn

Configure and build a kernel from source
Explore the Linux kernel architecture
Get to grips with key internals regarding memory management within the kernel
Understand and work with various dynamic kernel memory alloc/dealloc APIs
Discover key internals aspects regarding CPU scheduling within the kernel
Gain an understanding of kernel concurrency issues
Find out how to work with key kernel synchronization primitives
Who this book is for
This book is for Linux programmers beginning to find their way with Linux kernel development. Linux kernel and driver developers looking to overcome frequent and common kernel development issues, as well as understand kernel internals, will benefit from this book. A basic understanding of Linux CLI and C programming is required.
Discover how to write high-quality character driver code, interface with userspace, work with chip memory, and gain an in-depth understanding of working with hardware interrupts and kernel synchronization
Key Features:
Delve into hardware interrupt handling, threaded IRQs, tasklets, softirqs, and understand which to use when
Explore powerful techniques to perform user-kernel interfacing, peripheral I/O and use kernel mechanisms
Work with key kernel synchronization primitives to solve kernel concurrency issues
Book Description:
Linux Kernel Programming Part 2 - Char Device Drivers and Kernel Synchronization is an ideal companion guide to the Linux Kernel Programming book. This book provides a comprehensive introduction for those new to Linux device driver development and will have you up and running with writing misc class character device driver code (on the 5.4 LTS Linux kernel) in next to no time.
You'll begin by learning how to write a simple and complete misc class character driver before interfacing your driver with user-mode processes via procfs, sysfs, debugfs, netlink sockets, and ioctl. You'll then find out how to work with hardware I/O memory. The book covers working with hardware interrupts in depth and helps you understand interrupt request (IRQ) allocation, threaded IRQ handlers, tasklets, and softirqs. You'll also explore the practical usage of useful kernel mechanisms, setting up delays, timers, kernel threads, and workqueues. Finally, you'll discover how to deal with the complexity of kernel synchronization with locking technologies (mutexes, spinlocks, and atomic/refcount operators), including more advanced topics such as cache effects, a primer on lock-free techniques, deadlock avoidance (with lockdep), and kernel lock debugging techniques.
By the end of this Linux kernel book, you'll have learned the fundamentals of writing Linux character device driver code for real-world projects and products.
What You Will Learn:
Get to grips with the basics of the modern Linux Device Model (LDM)
Write a simple yet complete misc class character device driver
Perform user-kernel interfacing using popular methods
Understand and handle hardware interrupts confidently
Perform I/O on peripheral hardware chip memory
Explore kernel APIs to work with delays, timers, kthreads, and workqueues
Understand kernel concurrency issues
Work with key kernel synchronization primitives and discover how to detect and avoid deadlock
Who this book is for:
An understanding of the topics covered in the Linux Kernel Programming book is highly recommended to make the most of this book. This book is for Linux programmers beginning to find their way with device driver development. Linux device driver developers looking to overcome frequent and common kernel/driver development issues, as well as perform common driver tasks such as user-kernel interfaces, performing peripheral I/O, handling hardware interrupts, and dealing with concurrency will benefit from this book. A basic understanding of Linux kernel internals (and common APIs), kernel module development, and C programming is required.

Описание: Twenty five years ago, as often happens in our industry, pundits laughed at and called Linux a joke. To say that view has changed is a massive understatement. This book will cement for you both the conceptual `why` and the practical `how` of systems programming on Linux, and covers Linux systems programming on the latest 4.x kernels.
