Key Features
• Learn to develop customized Linux device drivers
• Learn the core concepts of device drivers such as memory management, kernel caching, advanced IRQ management, and so on.
• Practical experience on the embedded side of Linux
Book Description
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 to 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).
What you will learn
• Use kernel facilities to develop powerful drivers
• Develop drivers for widely used I2C and SPI devices and use the regmap API
• Write and support devicetree from within your drivers
• Program advanced drivers for network and frame buffer devices
• Delve into the Linux irqdomain API and write interrupt controller drivers
• Enhance your skills with regulator and PWM frameworks
• Develop measurement system drivers with IIO framework
• Get the best from memory management and the DMA subsystem
• Access and manage GPIO subsystems and develop GPIO controller drivers
