Linux Kernel Device Drivers
The Linux Kernel Device Drivers course at Sankalp Tech enables you to write, compile, and debug Linux device drivers for real hardware. It goes beyond theory to help you understand kernel internals, driver models, memory management, interrupts, and kernel–hardware interaction.
Ideal for professionals aiming to specialize in embedded Linux, this course provides hands-on labs and real driver programming experience.
