To make usage of the content of this book, a basic prior knowledge of C programming and basics Linux commands is expected. This book covers Linux drivers development for widely used embedded devices, using the kernel version v4.1, and covers changes until the last version at the time of writing this book (v4.13). This book is essentially intended for embedded engineers, Linux system administrators, developer, and kernel hackers. Whether you are a software developer, a system architect, or maker willing to dive into Linux driver development, this book is for you.

Overview of this book
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).
