Linux Device Drivers Development Course for Beginners

This beginner course introduces Linux device-driver development through sandbox setup, kernel and user-space concepts, loadable modules, file operations, and /proc filesystem programming. Learners create a kernel module, implement read operations, and pass data from kernel space to a user-space application.
