Linux device drivers are essential software components that enable the operating system to interact with hardware devices. They act as a bridge between the kernel and hardware, allowing the system to utilize various peripherals and components. In this guide, we’ll explore the basics of developing Linux device drivers using loadable kernel modules (LKMs). What are […]
Linux kernel modules are powerful tools that allow you to extend the functionality of the Linux operating system without modifying the core kernel code. In this guide, we’ll walk you through creating your first kernel module – a simple “Hello World” program. This hands-on approach will help you understand the basics of kernel module programming […]
Linux Loadable Kernel Modules (LKMs) are pieces of code that can be dynamically added to or removed from the Linux kernel while the system is running. They extend the kernel‘s functionality without requiring a full system reboot, providing flexibility and modularity to the Linux operating system. Advantages of LKMs Using LKMs offers several benefits over built-in kernel modules: Flexibility: Modules can be loaded […]
In the world of computing, two essential components work together to make our interactions with computers possible: the shell and the kernel. While both play crucial roles in operating systems, they serve distinct purposes and operate at different levels. Let’s explore these fundamental concepts and understand how they differ. What is a Shell? A shell […]
In the world of computing, two terms that often come up are “operating system” and “kernel.” While closely related, these components serve distinct purposes within a computer system.
