I need to modify the keyboard interrupt routine of the kernel to create a special command located at this level that shutdown the system.
Well, resuming I need:
1 - Discover what's the file to modify, I think the file is "keyboard.c" but the modifications that I do in this file don't take any effects;
2 - Discover what is the kernel functions to shutdown the system, I try this functions but they not work (kernel_hatl(), unlock_kernel(), do_exit(0))
Thanks for all.
