What is a Linux kernel driver?

A Linux Kernel Driver job involves developing, debugging, and maintaining device drivers that interface hardware with the Linux operating system. Kernel driver developers work with low-level system components, ensuring efficient communication between hardware and the OS. They often use languages like C and work with kernel subsystems, memory management, and concurrency. The role requires deep knowledge of Linux internals, debugging tools, and hardware interfaces. It is crucial for enabling hardware functionality in Linux-based environments.
