The goal is to provide a lightweight operating system able to use the safety features of the Rust language to be reliable. > This project is still in early stage development, thus it is highly unstable and misses a lot of features. **Do not use it in production!** To stay updated with the project, follow the [blog](https://blog.lenot.re)! <p align="center"> <img src="https://blog.lenot.re/assets/article/neofetch.png" alt="neofetch" width="100%" /> </p> [Neofetch](https://github.com/dylanaraps/neofetch) and bash running on the OS. # Features The following features are currently implemented (non-exhaustive): - Terminal with [VGA text mode](https://en.wikipedia.org/wiki/VGA_text_mode) and [PS/2](https://en.wikipedia.org/wiki/PS/2_port) keyboard (with forward compatibility with USB handled by the motherboard's firmware) - Partial support of [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) - Memory allocation/virtual memory - [Buddy allocator](https://en.wikipedia.org/wiki/Buddy_memory_allocation) - Internal memory allocator, with similarities with **dlmalloc**'s implementation, working on top of the buddy allocator - Processes and [scheduler](https://en.wikipedia.org/wiki/Scheduling_(computing)) ([round-robin](https://en.wikipedia.org/wiki/Round-robin_scheduling)) - POSIX signals - [PCI](https://en.wikipedia.org/wiki/Peripheral_Component_Interconnect) devices enumeration - Files: - Mountpoints - [IDE/PATA](https://en.wikipedia.org/wiki/Parallel_ATA) driver - Filesystem ([ext2](https://en.wikipedia.org/wiki/Extended_file_system) only for now) - Disk partitions ([MBR](https://en.wikipedia.org/wiki/Master_boot_record) and [GPT](https://en.wikipedia.org/wiki/GUID_Partition_Table)) - Virtual filesystems (`/tmp` and `/proc`) - initramfs - Time/Clock ([RTC](https://en.wikipedia.org/wiki/Real-time_clock)) - Linux system calls (roughly 30% are currently implemented) - Kernel modules - [ELF](https://en.wikipedia.org/wiki/Executable_and_Linkable_Format) programs # Quickstart This repository is not a full operating system in itself but only the kernel. You can either: - Use the [installer](https://github.com/maestro-os/maestro-install) to build a full operating system from an ISO file - Build the OS by hand. For this, you can check the kernel's book The OS can then be run by a virtual machine such a **QEMU** or **VirtualBox**, or on a physical machine. ## Build To build and/or run the OS, `cd` into the kernel's crate: ```sh cd kernel/ ``` Then follow the instructions in [README.md](kernel/README.md) ## Documentation The kernel's book contains general information on how to use the kernel. The book can be built using *mdbook*, with the command: ```sh mdbook build doc/ ``` Then, it can be accessed at `doc/book/index.html`.
