How to write a character device driver to read the processor's GDT
 

I wanna knw how user permissions are granted to the normal user to read the processor's GDT, the administrator will have complete access, but a normal user will not have the privileges, so trying to look into the same. Please lemme know the methods that needs to be implemented

If you want a device driver then have a look at cpuid code in /usr/src/linux/arch/x86/kernel/cpuid.c
