Kernel
Kernel is an educational hobby operating system and low-level systems programming project written in Rust. Designed for students and hobbyists, the project provides a minimalist environment to explore computer architecture, CPU design, and kernel development directly on hardware without relying on a standard library or underlying operating system.
The implementation features a freestanding language runtime and a custom target specification that replaces standard library components for bare-metal execution. It includes a multiboot bootloader interface to parse early-boot hardware handoff states, an interrupt descriptor table to route CPU exceptions and hardware interrupts, and direct hardware communication layers using both memory-mapped input-output and port-mapped hardware control mechanisms.
Features
- Operating System Kernels - Executes a basic operating system kernel to demonstrate low-level hardware interaction and systems programming concepts.
- CPU Port-Mapped Controls - Communicates directly with peripheral chips using dedicated CPU port instructions and low-level I/O mechanisms.
- Bare-Metal Runtimes - Provides a freestanding language runtime and custom target specification to replace standard library components for bare-metal execution.
- Interrupt Descriptor Tables - Implements an interrupt descriptor table to route CPU exceptions and external hardware interrupts to specific handler routines.
- Multiboot Standard Implementations - Parses early-boot hardware handoff states via a standardized multiboot bootloader interface.
- Memory-Mapped I/O Interfaces - Interacts directly with device registers and display buffers through designated physical memory addresses.
- Educational Environments - Provides a minimalist environment intended for students and hobbyists learning computer architecture directly on hardware.
- Operating System Development - Enables building a custom operating system kernel from scratch in Rust to explore low-level hardware interaction.
- Operating Systems - Builds a custom operating system kernel from scratch using Rust to explore low-level hardware interaction.
