Hi folks, I hope this is the correct way to ask for some help. I've recently cloned Grub2's code so I can try and add some functionality for a secure boot chain. I was looking at a friend's modifications to GRUB and noticed that they include <grub/cpu/io.h> but there is no cpu directory that exists (and subsequently, no io header). Confused, I checked GRUB's repo to see if the cpu directory exists and low-and-behold, it doesn't: https://git.savannah.gnu.org/cgit/grub.git/tree/include/grub.
What am I missing here? In addition, this is my first time setting up a GRUB development environment. My research has led me to install GDB. Is using GDB + a CLI the "correct" way to debug and step through GRUB? Thanks, Sean
