Age	Commit message (Collapse)	Author
11 days	add x86 supportHEAD master	Nathan Lee

2026-09-13	EFI boot header support	Nathan Lee

2026-08-30	add buddy allocator and remove the old freelist allocator	Nathan Lee
	- todo later: add other allocators (vmalloc + multi-page allocator) - todo later: initialize memory pages - the current kmalloc will not work anyways
2026-08-30	add support for printk printers in the formatter	Nathan Lee
	- todo: add support for size_t (currently, you can just cast to uintptr_t)
2026-08-30	fix typos + .data section issues	Nathan Lee

2026-08-28	rework early kernel init	Nathan Lee

2026-08-28	change kernel target	Nathan Lee

2026-08-12	move linker into arch-specific directory	Nathan Lee

2026-08-12	rework project structure	Nathan Lee

2026-08-03	create BuildConfig system	Nathan Lee

2026-08-03	create a simple CPIO parser for initrd's	Nathan Lee

2026-08-03	use a shared function for callback registration, for easier GOT linking	Nathan Lee

2026-07-30	create stub for syscalls	Nathan Lee

2026-07-29	create basic MMIO handler for console	Nathan Lee

2026-07-27	separate module ld from objcopy	Nathan Lee

2026-07-26	remove pci subsystem and replace it with console controllers	Nathan Lee

2026-07-26	feat: update ELF parser	Nathan Lee
	- added more header validity checks - create section name retrieval
2026-07-26	fix: km_init fails to find memory	Nathan Lee
	This resolves an issue where km_init would fail to find the memory property if it was not the first node that it looked at.
2026-07-26	create ringbuffer for logging	Nathan Lee

2026-07-19	update Makefile	Nathan Lee
	- removed echo - changed LD to actually use ld.lld
2026-07-12	create elf.h	Nathan Lee
	The ELF parser needs more work, there are more structs to be added. memcpy was refactored from mem.h into common.h endianness conversions were standardized in types.h
2026-06-25	create kzalloc	Nathan

2026-06-25	fix memory allocator logic	Nathan
	- fixed an edge case in `kmalloc` where the broken block from a split may be too small to accomodate another `struct page`. this was fixed such that if we do not have enough room to allocate another `struct page` then `kmalloc` simply returns the entire page. - fixed empty and single-element `free_list` edge cases in `kfree`
2026-06-24	update kmalloc	Nathan Lee

2026-06-24	create kmalloc and km_init	Nathan Lee

2026-06-19	create dtb allocator	Nathan Lee
	the parent commit (b106df2447d23d6b3fcffa7cc87edde218d054f3) discussed the possibility of creating dtb device discovery. for that, we have replaced wdt device discovery with dtb device discovery. in the future, we will use the pci kernel module to use device discovery via a PCI controller
2026-06-17	create wdt device discovery	Nathan Lee
	discuss: per wrv32em status, consider moving custom wdt format to dtb or pci device discovery (potentially both: we have the framework for pci.ko extension after using dtb to discover memory and pci devices)
2026-06-13	create support for kernel modules (but don't implement them yet)	Nathan Lee

2026-06-11	initial commit	Nathan Lee
