Bananymous c035d3c82c Kernel: Start all processors on kernel boot
Processors don't do anything, except print hello message and halt.

Bananymous 284a012509 Kernel: Add framebuffer information to kernel image 2023-12-09 17:33:58 +02:00
Bananymous 84040e64b8 Kernel: Don't use multiboot2 explicitly. Parse it to common structure
This allows support of multiple different bootloaders

Bananymous c17cdb39d5 Kernel: Map multiboot2 memory in PageTable initialization
It cannot be assumed that multiboot data lies between kernel_end
and 2 GiB mark, so I properly allocate virtual address space for it.

Bananymous 69a39b7077 Kernel: Start using multiboot2 instead of multiboot
This allows better compatibility with (U)EFI and gives RSDP location
instead of me having to scan ram to find it.

Bananymous 921d95d18f All: Clear lines with only whitspace in them 2023-09-10 00:31:42 +03:00
Bananymous f75adab9d8 Kernel: Move structures in boot.S to .data section 2023-08-11 00:26:12 +03:00
Bananymous 68691faca1 Kernel: boot.S is back to 2 MiB pages
bochs doesn't seem to support 1 GiB pages

Bananymous dcb23f686f Kernel: boot.S maps GiB as single pdpte 2023-05-31 00:51:15 +03:00
Bananymous 81cf389754 Kernel: Booting with higher half kernel gets to Heap initialization 2023-05-30 22:21:12 +03:00
Bananymous 0907965dc5 Kernel: start work on higher half kernel 2023-05-30 08:00:17 +03:00
Bananymous 210d90ec79 Kernel: We now identity map full GiB in boot.S
The paging structure is pre-built so no unnecessary calculations are done
2023-05-30 00:08:52 +03:00
Bananymous 6a3b3213cf Kernel: Kmalloc now has its memory statically allocated
We don't use the memory map given by bootloader since this automatically
maps the memory to a available space.

Bananymous df8811fc1a Kernel: Remove "a" from .section .text 2023-03-07 01:57:09 +02:00
Bananymous 06db890d49 Kernel: Add ubsan
My brain has been melting since I'm getting very random bugs.
I hope I can debug them better with ubsan :)

Bananymous 7fcbb869e1 Kernel: Initialize GDT in kernel code
We dont use the boot GDT only while booting
2023-03-01 21:21:56 +02:00
Bananymous 7f8cad83b1 Kernel: x86_64 boot script now makes GDT with null, kernel code and data 2023-03-01 21:21:56 +02:00
Bananymous cb3b62d665 Kernel: Only allocate single GDT entry during boot.S
When we need more, we should probably initialize rest of them
in cpp code
2023-01-31 18:43:09 +02:00
Bananymous 6418d7cfc3 Kernel: Add Other GDT entries to x86_64 2023-01-26 12:53:04 +02:00
Bananymous b315fdc27f Kernel: Finally managed to get 64-bit working
I had weird problems with interrupts but everything should work now
