In this webinar we investigate the why and how of managing peripheral devices in an Arm-based embedded Linux system. Although this is a huge and complex subject area, we can still introduce some of the key concepts and start to appreciate the steps involved in writing a device driver.
- How devices are represented in the device-tree description
- The basic framework used for a Linux kernel device driver
- Fundamentals of device driver programming, including interrupt handling and memory allocation
- How devices can be managed from user-space and a comparison with kernel-based management
- Some of the tools and techniques available for debugging device drivers.
