Writing A Simple Linux Kernel Module

The first example that is always depicted in understanding any coding language (or kernel programming in our case) is to write the hello world example. Let us write a simple kernel program which outputs ‘hello’ and ‘goodbye’.  Below is the sample code for the driver – it has comments placed to explain what each line […]
