Adding a Simple 'Hello World' Kernel Module - Step-by-Step Tutorial

In this step-by-step tutorial, I demonstrate how to add a simple "Hello World" kernel module to the Linux kernel. This module serves as a basic introduction to kernel module development and provides a foundation for understanding more advanced concepts.

I start by explaining the purpose and structure of kernel modules, highlighting their role in extending kernel functionality. We explore the benefits of modular design and the advantages of developing kernel modules.

Next, I guide you through the process of creating a basic kernel module that prints "Hello World" when loaded into the kernel. We discuss the necessary tools, headers, and libraries required for module development.

We delve into the code implementation, step by step, explaining each component and its significance. You'll learn how to handle module initialization, cleanup, and the basic structure of a kernel module.

I demonstrate how to compile the module and load it into the running kernel. We cover the necessary commands and options to compile the module, handle any dependencies, and install it.

Once the module is loaded, I show you how to observe the module's output and debug any potential issues. We explore techniques for monitoring kernel logs and examining module behavior.

Throughout the tutorial, I provide explanations, tips, and best practices to ensure a solid understanding of kernel module development. By the end of this video, you'll have a clear grasp of creating and loading a simple "Hello World" kernel module.
