I am still a pretty newbie beginner, I am trying to implement ps2 keyboard and I only have keyboard scan codes that I don’t know what to do with. github. Could anyone help me out?

Any good beginner 64 bit bootloader guides?
So would that bootloader load the the font into the kernel? Because I define everything inside the bootloader. You can look at it in main.c in gun-efi. https://github.com/VirusFusion/VirusFusionOS/blob/master/gnu-efi/bootloader/main.c

I can not make kernel or make run my OS on macOS
I have been trying to run my OS on my Mac after successfully running it on my windows PC with ubuntu 20.04 LTS wsl terminal. This is my GitHub if anyone wants to test it out and figure out the problem themselves https://github.com/VirusFusion/VirusFusionOS. I changed the makefile for my Mac and it fixed some errors. This is my macOS makefile https://pastebin.com/RPXUaXE1. When I try to run my kernel I get this error "make: *** [link] Illegal instruction: 4" and when I try to make run for Qemu I also get this error "qemu-system-x86_64 -drive file=bin/VirusFusionOS.img -m 256M -cpu qemu64 -drive if=pflash,format=raw,unit=0,file="../OVMFbin/OVMF_CODE-pure-efi.fd",readonly=on -drive if=pflash,format=raw,unit=1,file="../OVMFbin/OVMF_VARS-pure-efi.fd" -net none

A self-hosting and educational C optimizing compiler
Yes, consider the case of shecc. It requires just a handful of C code lines to interpret directives set in the C preprocessor. Unlike relying on existing tools like cpp, as, or ld, shecc stands alone as a minimalist cross-compiler. This design could be particularly beneficial for students delving into the study of compiler construction. See https://github.com/sysprog21/shecc/blob/master/src/lexer.c#L...

Compiler Class
I'm looking at this one for a CPU design I've been working on. :)
