This is a toy operating system I wrote from scratch as part of Cal Poly's CPE 454 - Implementation of Operating Systems course.
It currently targets x86_64, but there's nothing preventing it from being ported to other platforms.
It supports:
- Virtual Memory and automatic physical memory detection from multiboot headers
- PS2 keyboards
- Graphical console (currently targeting IBM's standard VGA Text Mode)
- Serial console
- Kernel-space threads and scheduling (with blocking queue support)
- ATA block devices
It's a little rough right now, but I hope to clean it up at some point it the future and add proper filesystem and userspace support.
All the code was written from scratch by me, with these exceptions:
- The course provided some snippets to help us properly bootstrap the CPU to long mode (see
arch/x86_64/boot.asm) - The snakes demo program to stress test our multithreading was written by Professor Niko for his operating systems course (see
init/snakes.cpp).
