Use kernel facilities to develop powerful drivers

Learn core concepts for developing device drivers using a practical approach

Program a custom character device to get access to kernel internals

Description

Linux is a unified kernel that is widely used to develop embedded systems. As Linux has turned out to be one of the most popular operating systems worldwide, the interest in developing proprietary device drivers has also increased. Device drivers play a critical role in how the system performs and ensure that the device works in the manner intended. By exploring several examples on the development of character devices, the technique of managing a device tree, and how to use other kernel internals, such as interrupts, kernel timers, and wait queue, you’ll be able to add proper management for custom peripherals to your embedded system. You’ll begin by installing the Linux kernel and then configuring it. Once you have installed the system, you will learn to use different kernel features and character drivers. You will also cover interrupts in-depth and understand how you can manage them. Later, you will explore the kernel internals required for developing applications. As you approach the concluding chapters, you will learn to implement advanced character drivers and also discover how to write important Linux device drivers. By the end of this book, you will be equipped with the skills you need to write a custom character driver and kernel code according to your requirements.

What you will learn

I’m one of those Linux users who wants to deepen his knowledge into notions that I’ve always found hard to explore: the web offers information here and there, but the point is how to connect the dots together. This book offers exactly what I was looking for: a very useful cookbook that, step by step, introduces the reader to concepts like device tree, interrupt management and atomic operation. All of this is done using a practical approach with examples and snippets of code. Thanks to this book, I could eventually comprehend the nuances between mutexes and spinlock and understand the kernel timer management… the author has definitely removed the fog! I do suggest this book to anyone: both newbies and experts can find such reading extremely useful for their daily job.

I got kindle edition today. But I can't read this book because the edit state is a mess(See the location 900 ~ 1000 pages). Publishing officials should check the publication status right now. Send me a readable book..chunghan.yi@gmail.com
