The Zephyr Project is a new generation real-time operating system (RTOS) that supports multiple hardware architectures. It is based on a small-footprint kernel specially designed for use on resource-constrained and embedded systems. The Zephyr OS can be used for a wide range of applications: from simple embedded environmental sensors and LED wearables to sophisticated embedded controllers, smart watches, and IoT wireless applications.

We love macOS, but we’re not a fan of the ever-closing hardware and ecosystem. So we are creating ravynOS, an OS aimed to provide the finesse of macOS with the freedom of FreeBSD. This is a developer preview image that’s mainly intended for helping build the system. We recommend running in a virtual machine, although it should work on any hardware supported by FreeBSD-CURRENT (14.0) with at least 2GB (8GB recommended) RAM. PLEASE NOTE: On 2022-02-14, we decided to abandon the current path of using X11/KDE desktop components and write from scratch a new UI that will align better with our goals. This stepping back will slow the project but ultimately should result in a better outcome. We intend to bring many of the features you’ve come to love from macOS to ravynOS like clean design, global menus, and drag-and-drop installs. All of your FreeBSD ports and apps, Linux apps, and even trivial Darwin & macOS binaries can now run on ravynOS. And we’re actively working on improving it!

ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.

This project maintains the Linux Console tools, which include utilities to test and configure joysticks, connect legacy devices to the kernel's input subsystem (providing support for serial mice, touchscreens etc.), and test the input event layer.

ToaruOS is a "complete" operating system for x86-64 PCs and experimental support for ARMv8. While many independent, hobby, and research OSes aim to experiment with new designs, ToaruOS is intended as an educational resource, providing a representative microcosm of functionality found in major desktop operating systems. The OS includes a kernel, bootloader, dynamic shared object linker, C standard library, its own composited windowing system, a dynamic bytecode-compiled programming language, advanced code editor, and dozens of other utilities and example applications. There are no external runtime dependencies and all required source code, totaling roughly 100k lines of (primarily) C, is included in this repository, save for Kuroko, which lives separately. Through out the project, ToaruOS has also attracted quite a few beginner OS developers who have tried to use it as a reference.

The Xbox Linux Project aims to privide a version of GNU/Linux for the Xbox, so that it can be used as an ordinary computer. Linux should make use of all Xbox hardware and allow to install and run software from standard i386 Linux distributions.

FreeDOS is an open source DOS-compatible operating system that you can use to play classic DOS games, run legacy business software, or write new DOS programs. Any program that works on MS-DOS should also run on FreeDOS.

October 2025 ISOs have been released! 3 new ISOs - PLASMA, GNOME, XFCE have been released. Thank you to all the members in the ALG community for their support.

IEEE 802.1d ethernet bridging (plus Spanning Tree protocol) for the linux kernel. Kernel code is in Linux 2.4 and 2.6 kernels.

xone is a Linux kernel driver for Xbox One and Xbox Series X|S accessories. It serves as a modern replacement for Xpad, aiming to be compatible with Microsoft's Game Input Protocol (GIP). Installing Xone will disable the Xpad kernel driver. If you are still using Xbox or Xbox 360 peripherals, you will have to install xpad-noone as a replacement for Xpad.

Providing an easy to use platform for running Ancient UNIX & BSD on windows.

A port of the Linux operating system kernel and assorted GNU userspace to the GameCube and Wii gaming consoles from Nintendo. Please, see http://www.gc-linux.org for additional information.

Please find the linuxwacom project's new home on Github: https://linuxwacom.github.io/ Previous Description: This project manages the libraries, configuration, and diagnostic tools for Wacom tablets running under Linux. It also maintains updated Linux kernel drivers and Xorg/XFree86 XInput drivers.

Tilck is a tiny, monolithic operating system kernel designed to be partially compatible with Linux at the binary level while maintaining extreme simplicity, low latency, and minimal resource usage. It is built primarily as an educational project, allowing developers to experiment with kernel development while still being able to run real Linux user-space applications without modification. The kernel is written in C and designed to run on architectures such as i686 and RISC-V, with future plans for broader hardware support. One of its defining characteristics is its deterministic behavior and very small memory footprint, enabling it to run on systems with extremely limited resources. Unlike Linux, tilck intentionally avoids complexity and large-scale features, focusing instead on clarity, robustness, and ease of understanding. It includes its own bootloader and supports integration with existing ones like GRUB, making it flexible for experimentation.

Cryptic Allusion Dreamcast-related development: KallistiOS, Ghetto Pong, etc.

An effort towards porting Linux and related open source operating systems to the Xbox 360. Another goal is to write homebrew applications with a legal and free Software Development Kit consisting of the Library (LibXenon) and the appropriate cross-compiler toolchain (Xenon-Toolchain). You can get informations and Source-Code on the following Pages: Wiki: http://www.free60.org Forum: http://www.libxenon.org Source Code: https://github.com/Free60Project

EasyPeasy is a lightweight operating system for netbooks, designed for the Internet and low power consumption.

This is the source release of the NVIDIA Linux open GPU kernel modules, version 530.41.03. Note that the kernel modules built here must be used with GSP firmware and user-space NVIDIA GPU driver components from a corresponding 530.41.03 driver release. Currently, the kernel modules can be built for x86_64 or aarch64. If cross-compiling, set these variables on the make command line. Any reasonably modern version of GCC or Clang can be used to build the kernel modules. Note that the kernel interface layers of the kernel modules must be built with the toolchain that was used to build the kernel. This code base is shared with NVIDIA's proprietary drivers, and various processing is performed on the shared code to produce the source code that is published here. When packaged in the NVIDIA .run installation package, the OS-agnostic component is provided as a binary.

Zen Patched Kernel Sources. This is the top level of the kernel’s documentation tree. Kernel documentation, like the kernel itself, is very much a work in progress; that is especially true as we work to integrate our many scattered documents into a coherent whole. ARC processors are highly configurable and several configurable options are supported in Linux. Some options are transparent to software (i.e cache geometries, some can be detected at runtime and configured and used accordingly, while some need to be explicitly selected or configured in the kernel’s configuration utility.
