# 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
|
