Linux Device Drivers Development

Develop Linux device drivers from scratch, with hands-on guidance focused on embedded systems, covering key subsystems like I2C, SPI, GPIO, IRQ, and DMA for real-world hardware integration using kernel 4.13

Key Features

• Develop custom drivers for I2C, SPI, GPIO, RTC, and input devices using modern Linux kernel APIs
• Learn memory management, IRQ handling, DMA, and the device tree through hands on examples
• Explore embedded driver development with platform drivers, regmap, and IIO frameworks

Book Description

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
