Example of a Simple Linux Kernel Driver

Let's take a look at a simple example of a Linux kernel driver. This is a basic 'Hello, World!' driver. It doesn't do much, but it's a good starting point to understand the structure of a Linux driver. This code is written in C, which is the primary language for Linux kernel development.

#include 
#include 
#include 
MODULE_LICENSE("GPL");
MODULE_AUTHOR("Your Name");
MODULE_DESCRIPTION("A simple Linux driver for beginners");
MODULE_VERSION("0.1");
static int __init hello_init(void) {
   printk(KERN_INFO "Hello, World!\n");
   return 0;
}
static void __exit hello_exit(void) {
   printk(KERN_INFO "Goodbye, World!\n");
}
module_init(hello_init);

module_exit(hello_exit);

In this code, we first include the necessary header files. Then we define some information about the module (like its license and author) using MODULE macros. The 'hello_init' function is called when the module is loaded into the kernel, and 'hello_exit' is called when it's removed. The 'printk' function is used to print messages to the kernel log, which can be read with the 'dmesg' command. This is a very basic example, but it serves as a good starting point for understanding Linux kernel driver development.

🛠️ Your Toolkit: Practical Tips to Kickstart Your Linux Kernel Driver Development Adventure
