AV's Rusty OS

Operating System made in Rust for x86-64 machines. A new alternative to Windows, Linux, and MacOS!

Description

AV OS is an experimental, bare-metal operating system kernel built in Rust. Designed as a no_std environment, it circumvents the standard library to establish low-level control over hardware.

The project has these features:

• Hardware Interface: Manages the system via VGA buffer for text display and serial port communication. Now comes with different colors in chaos mode!

• Custom Shell Application: Boots up by default. Has a couple of commands for managing memory(writing files) and misc.

• Asynchronous Architecture: Implements a cooperative multitasking model using a custom Executor, enabling task management

• Memory Management: Uses a physical memory frame allocator and a virtual memory mapper to support a dynamic heap. Uses Linked List Allocator

Overall, I learned a lot during this project... 25 hours of gibberish. Between Rust and C, I think Rust was easy to learn and use.

Demo

In case you don't want to install and run it, here's a little demo of how it would look!

Dependencies

• In case it's not obvious, you'll need to run Rust code. Make sure you have cargo, and rustup!
• Rust Nightly, to run unsafe features. Install using rustup default nightly
• rust-src, install using rustup component add rust-src
• bootimage, install usign cargo install bootimage
• You will need some way to run the .bin file. I've been using QEMU as an emulator, but you could boot to a Real x86-64 Machine

Installing

• Go to releases and download the latest bootimage-av_os.bin file.
• Or, if you've installed all the dependencies, then run the commands:
  • cargo build --release
  • cargo bootimage --release
  • Go to terminal and make sure you're in the same directory as target\x86_64-av_os\release\
  • There, you will find the bootimage-av_os.bin file!

Executing program

If you are using QEMU as emulator

• Make sure you have installed QEMU
• Open terminal and navigate to the same folder as your bootimage-av_os.bin
• Then, run the command: qemu-system-x86_64 -drive file=bootimage-av_os.bin,format=raw
• Enjoy the magic!

If you are running on a real machine

• I've never tested on a real machine...
• So... I'm not really sure...
• I think you need a USB or something

Warning

I've never ran this code on a real machine. It might work great! It might explode :( I am not liable for whatever happens!!
