When searching GitHub for "Linux Kernel Programming," you will find repositories that serve as companions to popular books. These are often more valuable than the books themselves because they are updated.
The Linux kernel is the core of the Linux operating system, responsible for managing hardware resources, providing basic services to applications, and facilitating communication between hardware and software components. Linux kernel programming involves developing and modifying kernel code to create custom kernel modules, device drivers, and system utilities. Linux kernel programming requires a strong foundation in C programming, computer science fundamentals, and a deep understanding of the Linux operating system.
Create a file named Makefile in the exact same directory as your C source code:
Learn how to create virtual files under /dev/ that allow user-space applications to stream data directly to and from your kernel module using read() and write() system calls.
