Developing Linux Device Drivers (LFD430) Learn how to develop device drivers for Linux systems. This course will teach you about the different types of Linux device drivers as well as the appropriate APIs and methods through which devices interface with the kernel. Device Drivers A global device hierarchy allows each device in the system to be represented in a com-mon way. This allows the core to easily walk the device tree to do such things as prop-erly ordered power management transitions. Struct devicedriverin Listing 1 de-ﬁnes a simple set of operations for the core to perform these actions on each device. Linux device drivers (second edition). This book is available for free on the internet. Jonathan Corbet. Porting device drivers to the 2.6 kernel. This is a very valuable resource for porting drivers to the new 2.6 Linux kernel and also for learning about Linux device drivers. Device drivers literally drive everything you're interested in-disks, monitors, keyboards, modems-everything outside the computer chip and memory. And writing device drivers is one of the few areas of programming for the Linux operating system that calls for unique, Linux-specific knowledge.

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:

struct platform_device_id {char name[PLATFORM_NAME_SIZE];kernel_ulong_t driver_data;};

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).
