PixieOS

PixieOS is a minimal operating system kernel written in Rust. This project aims to create a basic OS from scratch, demonstrating low-level programming concepts and Rust's capabilities in systems programming.

Features

• Bare-metal Rust implementation
• Custom target specification for x86_64 architecture
• VGA text mode output
• Panic handler implementation

Prerequisites

To build and run PixieOS, you need:

• Rust nightly toolchain
• cargo-bootimage for creating bootable disk images
• QEMU for running the OS (optional, but recommended for testing)

Setup

1. Install the Rust nightly toolchain:

   rustup override set nightly
   

2. Install cargo-bootimage:

   cargo install bootimage
   

3. Install QEMU (if not already installed)

Building

To build the project, run:

cargo build

Running

To create a bootable image and run it in QEMU, use:

cargo run

Project Structure

• src/main.rs: Contains the kernel entry point and basic VGA buffer output
• Cargo.toml: Rust package manifest
• rust-toolchain: Specifies the Rust toolchain version
• .cargo/config.toml: Cargo configuration for custom target and runner
• x86_64-pixie_os.json: Custom target specification for x86_64
