I Wrote A OS For Neuro-Sama(AI Vtuber), also a tribute I used to TempleOS, Its 64-Bit UEFI!
Its MIT License And Open Source, Welcome Fork!

My operating system has these features:
- HDAudio & AC97
- SATA & FAT32 & GPT & AHCI & RedSea
- JIT & HolyC-JIT & HolyNeuro-JIT
- La57
- MSI & INTx & MSI-X
- REP MOVS/STOS & AVX256 & SSE1~SSE4.2 & NT(Non-Temporal) & FPU
- PS/2 Keyboard & PS/2 Mouse
- Identical mapping
- I/O APIC
- ACPI
- SIPI
- IPI
- INIT
- GOP
- CISC Instruction Length Parser(In IDT)
- Ring0
- KMalloc
- WAV
- AMP
- WM
- GUI(But ugly)
- Task

Under development:
- xHCI
- xHCI Keyboard & xHCI Mouse

Features under planning:
- E1000
- IwlWiFi
- E1000E

For me, this is unnecessary: ​
- Ring3
- Non-identical mapping
- eHCI & oHCI & uHCI

CC:
clang
LD:
ld.lld
AS:

I wrote this by reading Intel manuals. I don't look at other OS codebases.

But, Im Sorry, Because I Got Ban In Github, So All Github Link Is 404, Im Trying Upload File To My Web

Interesting! You may have mentioned it and I did not see (I looked at the Github but not the website), how come you don't plan to have a Ring 3/userland?

I don't really like ring 3, so I'm using a pure ring 0 system.
Moreover, this project is a tribute to Terry A. Davis and is a fan work of Neuro-Sama (the AI Vtuber).

Where is the folder organization

I just like flat structure. That's intentional.

I del HDAudio,And rewrite

VirtIO Is ****

No GPU, Only CPU

HDAudio Polling is EZ, Right?

direct mapping粪完了，你猜猜为什么amd要在64位模式下强制开启分页

Translation: Direct mapping sucks. Guess why did AMD force enabling paging in 64-bit mode.

不过小学生能拾起一样爱好当然难能可贵，至少比我这个老废物强

啥？

I Think SDL Is Better Then GTK.
