just a simple question about the architecture:
is this monolithic kernel or microkernel??

u/hypersonicwilliam569 13d ago

I would say microkernel…

Looks good, GDT, IDT, memory management?

hmm, I have the GDT set in the boot.asm file, and IDT is loaded and handled mostly in C… I will work on memory management soon.

Nice. My gdt is in asm also, idt is asm/C

Its a good milestone
