Linux Device Drivers Development

This is the code repository for Linux Device Drivers Development, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.

Instructions and Navigation

All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter02.

The code will look like the following:

Linux kernel is a complex, portable, modular and widely used piece of software, running on around 80% of servers and embedded systems in more than half of devices throughout the World. Device drivers play a critical role in how well a Linux system performs. As Linux has turned out to be one of the most popular operating systems used, the interest in developing proprietary device drivers is also increasing steadily.

This book will initially help you understand the basics of drivers as well as prepare for the long journey through the Linux Kernel. This book then covers drivers development based on various Linux subsystems such as memory management, PWM, RTC, IIO, IRQ management, and so on. The book also offers a practical approach on direct memory access and network device drivers.

By the end of this book, you will be comfortable with the concept of device driver development and will be in a position to write any device driver from scratch using the latest kernel version (v4.13 at the time of writing this book).

msleep(2000); wake_up_interruptible(&my_data->my_wq); 

should include an extra line of code in between as shown here:

msleep(2000); sleep = 1; wake_up_interruptible(&my_data->my_wq);

Linux Device Driver Development Cookbook

This is the code repository for Linux Device Driver Development Cookbook, published by Packt.

Develop custom drivers for your embedded Linux applications

Device drivers play a critical role in how the system performs and ensures that the device works in the intended way. With a recipe based approach this book gives you practical recipes on character drivers and related kernel internals. It shows you how to start writing Linux device drivers and tools to understand, debug or modify them.

This book covers the following exciting features:

• Become familiar with the latest kernel releases (4.19+/5.x) running on the ESPRESSObin devkit, an ARM 64-bit machine
• Download, configure, modify, and build kernel sources
• Add and remove a device driver or a module from the kernel
• Master kernel programming
• Understand how to implement character drivers to manage different kinds of computer peripheral
• Become well versed with kernel helper functions and objects that can be used to build kernel applications
• Acquire a knowledge of in-depth concepts to manage custom hardware with Linux from both the kernel and user space

If you feel this book is for you, get your copy today!

Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

[ 3.421397] mvneta d0030000.ethernet eth0: Using random mac address 3e:a1:6b: f5:c3:2f 

Following is what you need for this book: This book will help anyone who wants to develop their own Linux device drivers for embedded systems. Having basic hand-on with Linux operating system and embedded concepts is necessary.

With the following software and hardware list you can run all code files present in the book (Chapter 1-9).

Software and Hardware List

Chapter	Software required	OS required
1-7	Text editor such as vi , emacs, or nano	Ubuntu 18.04.1 LTS Linux, Windows, macOS
