Linux Kernel Programming Part 2 — Char Device Drivers and Kernel Synchronization

Description

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.

Get to Know the Author

Kaiwan N Billimoria taught himself BASIC programming on his dad’s IBM PC back in 1983. He was programming in C and Assembly on DOS until he discovered the joys of Unix, and by around 1997, Linux!

Kaiwan has worked on many aspects of the Linux system programming stack, including Bash scripting, system programming in C, kernel internals, device drivers, and embedded Linux work. He has actively worked on several commercial/FOSS projects. His contributions include drivers to the mainline Linux OS and many smaller projects hosted on GitHub. His Linux passion feeds well into his passion for teaching these topics to engineers, which he has done for well over two decades now. He’s also the author of Hands-On System Programming with Linux. It doesn’t hurt that he is a recreational ultrarunner too.
