TeaOS is a teaching-oriented operating system designed for learning modern OS principles. It targets x86_64 architecture and includes multicore support, virtual memory management, and preemptive scheduling.
The kernel is organized into clear subsystems: process scheduling, memory management, a virtual file system, device drivers, and a network stack. A hardware abstraction layer (HAL) isolates architecture-specific code such as interrupt handling, context switching, CPU initialization, and page-table management. A custom bootloader brings the system up before handing control to the kernel.
Key features:
- Modern x86_64 support: 64-bit long mode with SMP/multicore
- Virtual memory: page tables and memory mapping
- Preemptive scheduling: process management and scheduler
- VFS and drivers: extensible file-system and device-driver interfaces
- Educational documentation: architecture, kernel, memory, scheduler, and driver docs
The project is built with a standard x86_64 cross-compilation toolchain, NASM, QEMU, and Make. It is intended for classroom use and self-study of operating-system internals.
