anubisos's Issues

Define a global descriptor table (GDT)

Provide interrupt handler code for CPU interrupts

x86_64-elf-gcc: not found

currently in mental breakdown trying to figure out where the fuck i can get this TwT

Let the CPU know where the IDT lives

Define an interrupt descriptor table (IDT)

Let the CPU know where the GDT lives

i hate c and asm

follow up todo

in order to adress the previous issue i figured out that before implementing keyboard driver i need plenty of other things like an IDT
