Linux Driver Code to print machine name, system name, release and Version

init_uts_ns(init/version.c) variable in Linux Kernel contains the information about:

• Operating system name (e.g., "Linux")
• Operating system release (e.g., "2.6.28")
• Operating system version
• Hardware identifier

When you run 'uname' command from user space, values from above structure are retrieved.

Code

	#include <linux/module.h>
	#include <linux/kernel.h>
	#include <linux/types.h>
	#include <linux/utsname.h>
	#include <linux/errno.h>
	static void data_cleanup(void)
	{
	/* never called */
	}
	static int data_init(void)
	{
	/* print information and return an error */
	printk("Machine Name: %s\n",init_uts_ns.name.machine);
	printk("System Name: %s\n",init_uts_ns.name.sysname);
	printk("Release: %s\n",init_uts_ns.name.release);
	printk("Version: %s\n",init_uts_ns.name.version);
	return 0;
	}
	module_init(data_init);
	module_exit(data_cleanup);
	MODULE_LICENSE("GPL");
