Mastering Linux Device Driver Development

Chapter 1: Linux Kernel Concepts for Embedded Developers

As a standalone software, the Linux kernel implements a set of functions that help not to reinvent the wheel and ease device driver developments. The importance of these helpers is that it’s not a requirement to use these for code to be accepted upstream. This is the kernel core that drivers rely on. We’ll cover the most popular of these core functionalities in this book, though other ones also exist. We will begin by looking at the kernel locking API before discussing how to protect shared objects and avoid race conditions. Then, we will look at various work deferring mechanisms available, where you will learn what part of the code to defer in which execution context. Finally, you will learn how interrupts work and how to design interrupt handlers from within the Linux kernel.

This chapter will cover the following topics:

  • The kernel locking API and shared objects
  • Work deferring mechanisms
  • Linux kernel interrupt management

Let’s get started!

Key benefits

  • Stay up to date with the Linux PCI, ASoC, and V4L2 subsystems and write device drivers for them
  • Get to grips with the Linux kernel power management infrastructure
  • Adopt a practical approach to customizing your Linux environment using best practices
  • Purchase of the print or Kindle book includes a free eBook in the PDF format

Description

Linux is one of the fastest-growing operating systems around the world, and in the last few years, the Linux kernel has evolved significantly to support a wide variety of embedded devices with its improved subsystems and a range of new features. With this book, you’ll find out how you can enhance your skills to write custom device drivers for your Linux operating system. Mastering Linux Device Driver Development provides complete coverage of kernel topics, including video and audio frameworks, that usually go unaddressed. You’ll work with some of the most complex and impactful Linux kernel frameworks, such as PCI, ALSA for SoC, and Video4Linux2, and discover expert tips and best practices along the way. In addition to this, you’ll understand how to make the most of frameworks such as NVMEM and Watchdog. Once you’ve got to grips with Linux kernel helpers, you’ll advance to working with special device types such as Multi-Function Devices (MFD) followed by video and audio device drivers. By the end of this book, you’ll be able to write feature-rich device drivers and integrate them with some of the most complex Linux kernel frameworks, including V4L2 and ALSA for SoC.

Who is this book for?

This book is for embedded developers, Linux system engineers, and system programmers who want to explore Linux kernel frameworks and subsystems. C programming skills and a basic understanding of driver development are necessary to get started with this book.

What you will learn

  • Explore and adopt Linux kernel helpers for locking, work deferral, and interrupt management
  • Understand the Regmap subsystem to manage memory accesses and work with the IRQ subsystem
  • Get to grips with the PCI subsystem and write reliable drivers for PCI devices
  • Write full multimedia device drivers using ALSA SoC and the V4L2 framework
  • Build power-aware device drivers using the kernel power management framework
  • Find out how to get the most out of miscellaneous kernel subsystems such as NVMEM and Watchdog

I already read the first book of John Madieu and i would like to thank him once more for his advices.A few years ago i had no idea about linux, Embedded systems, yocto, buildroot and drivers, thanks to John Madieu i learned how to go through with and i am still learning. I've been working for John Madieu in His company LABCSMART, and i saw its determination while writing. I learn a lot with his books.

Full disclosure: I'm a fellow author for Packt Publishing.If you have a solid understanding of C-language programming and want to branch out into Linux device driver development, then this is the book for you. It's well-written, with clear explanations of concepts and code. It begins with an explanation of Linux kernel basics, and then progresses into explanations about how to create various types of drivers, for both normal and embedded systems. So, if you want to learn about creating drivers, go ahead and grab a copy without delay.

I have been reading this book for about 2 weeks now and it is really good. The author presents a lot of useful information in a very straight forward format. I wish this book had been around years ago when I was writing Ethernet drivers.

It covers all the topics and uses newer kernels. It focuses more on the frameworks and is crisp and concise. This is a good reference book if you already understand kernel and driver development and have some experience with it. This not an Introductory book on driver development and kernel programming.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

What is Early Access? Chevron down icon Chevron up icon

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.
