XunilOS

XunilOS is an OS made from scratch in Rust. The repo is based on the limine-rust-template.

It supports aarch64 inside QEMU, and x86_64 even on bare machines!

Features

Kernel

x86_64 IDT, GDT, interrupts, kernel heap, PS2 mouse/keyboard, paging, syscalls and usermode.
aarch64 kernel heap, paging, interrupts, Virtio mouse/keyboard, syscalls, usermode
Scheduler which does round-robin switching as well as sleeping and waking processes
ELF64 ET_EXEC and ET_DYN loading, verifying and running support
A readonly VFS which currently includes the ELF files which can be ran
IPC with granular permissions (read, write, manage)
basic (and insecure) SHM support
Limine bootloader
Framebuffer and serial support
Timing support based on IRQ
Per-process address space, kernel & user stack
Copy to and from userspace

Apps

doomgeneric: Doom ported to XunilOS. Isn't as easy, as i am using Rust and had to write my own libc stub.
badapple: Grayscale Bad Apple by using numbers to represent shades of gray. Pretty easy, but this is the only place where I also used Python.
shell: simple shell with elf running, echo and file read commands.
helloworld: just prints helloworld to serial

Desktop-like experience
Window Management (close and minimize)
Start menu to open applications
BMP background
Mouse support with a BMP image

Basic functions of C (printf, strlen, etc)
File I\O, IPC, time
