Bananymous c4670f49d4 Kernel: Refactor some IDT code 2023-01-25 19:19:28 +02:00
Bananymous ba53582f23 Kernel: Rewrite APIC and PIC more OOP friendly
x86_64 port is slowly coming together
2023-01-23 20:13:57 +02:00
Bananymous 54043288cb Kernel: Move CPUID out of arch/
CPUID instructions behaves the same on x86 and x86_64. I am not
planning on supporting any non x86 based architectures.

Bananymous 1b9f7aa815 Kernel: Rewrite the whole VESA driver
We dont support vga text mode currently. I might add it later if needed.

I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer

Bananymous cdd27ae3db Kernel: rename MMU::m_page_directory_pointer_table -> m_highest_paging_stuct
This might not always be pdpt. In x86_64 it is pml4/pml5
