XT Operating System

XT Operating System is a modern, multitasking, and multiprocessor operating system designed for 64-bit architectures. Developed by Timur Nazhmetdinov, the project focuses on minimalism and portability, maintaining a very thin dependency layer.

Key Features

• Multitasking: Efficient handling of concurrent processes.

• Multiprocessing (SMP): Designed to utilize multiple CPU cores.

• Minimal Dependencies: Requires only UEFI headers and a printf implementation.

• Architecture-Ready: Built with future multi-architecture support in mind.

• 64-bit Native: Engineered strictly for systems with virtual addressing and at least a 64-bit word size.

---

Roadmap

• Bootloader: Completed and functional.

• Kernel Memory Manager: Currently in development.

• Scheduler: Refinement for multi-core multitasking.

• Multi-architecture Support: Porting to other 64-bit platforms.

• User-space Environment: Libraries and basic shell.

Prerequisites

Before building the project, ensure you have the following:

1. UEFI Headers: You must have UEFI headers installed on your system.

2. Configuration: Specify the path to your UEFI headers in the config.mk file.

Building the System

The build process is divided into two main stages:

1. Environment Setup:

   Bash

   make setup
   

2. Compilation:

   Bash

   make build

Running XT OS

To test the operating system, use the pre-configured QEMU command:

Bash

make run

---

License

This project uses a layered licensing model:

• GNU GPL: Applied to the Kernel and System Components.

• GNU LGPL: Applied to User-space Libraries.
