Practical Embedded Linux Device Drivers is designed to give engineers the knowledge and skills to work confidently with all the components of the kernel to successfully develop device drivers.. Workshops comprise approximately 50% of this 4-day training course, with carefully designed hands-on exercises to reinforce learning.

SysFS in Linux Kernel Tutorial. Sysfs is a virtual filesystem exported by the kernel, similar to /proc. The files in Sysfs contain information about devices and drivers. Some files in Sysfs are even writable, for configuration and control of devices attached to the system. Sysfs is always mounted on /sys. Practical Embedded Linux Device Drivers is designed to give engineers the knowledge and skills to work confidently with all the components of the kernel to successfully develop device drivers.
