This project is a freestanding kernel written in Rust that boots on x86 hardware without a standard library. It serves as a low-level system implementation focusing on the creation of a bare metal operating system.
The system implements a bootable disk image toolchain that transforms source code into binaries compatible with a bootloader. It features a custom memory allocator for dynamic memory management and an x86 kernel implementation that includes paging, interrupt handling, and VGA text mode.
The project covers several core capability areas, including low-level memory management through paging and frame allocation, CPU interrupt handling for exception management, and the development of a multitasking system using asynchronous execution patterns. It also provides a workflow for building freestanding binaries, managing build environments via containers, and verifying kernel logic through integration tests.
The compiled disk images can be executed on physical hardware via USB drives or run within virtual machines and emulators for testing.
