WSL2-Linux-Kernel
The source for the Linux kernel used in Windows Subsystem for Linux 2
The WSL2-Linux-Kernel repo contains the kernel source code and configuration files for the WSL2 kernel. If you discover an issue relating to WSL or the WSL2 kernel, please report it on the WSL GitHub project. It is not possible to report issues on the WSL2-Linux-Kernel project. Instructions for building an x86_64 WSL2 kernel with an Ubuntu distribution are provided. The number one way that we recommend you run Linux distributions is by installing Windows Terminal. Using Windows Terminal enables you to open multiple tabs or window panes to display and quickly switch between multiple Linux distributions or other command lines (PowerShell, Command Prompt, PowerShell, Azure CLI, etc). You can fully customize your terminal with unique color schemes, font styles, sizes, background images, and custom keyboard shortcuts. -

Redox
Redox is an operating system written in Rust
Redox is a Unix-like Operating System written in Rust, aiming to bring the innovations of Rust to a modern microkernel and full set of applications. Redox is a general purpose operating system written in pure Rust. Our aim is to provide a fully functioning Unix-like microkernel, that is both secure and free. We have modest compatibility with POSIX, allowing Redox to run many programs without porting. We take inspiration from Plan9, Minix, Linux, and BSD. Redox aims to synthesize years of research and hard won experience into a system that feels modern and familiar. Redox is an attempt to make a complete, fully-functioning, general-purpose operating system with a focus on safety, freedom, reliability, correctness, and pragmatism. We want to be able to use it, without obstructions, as an alternative to Linux on our computers. It should be able to run most Linux programs with only minimal modifications. We're aiming towards a complete, safe Rust ecosystem. -

Linux Surface
Linux Kernel for Surface Devices
Linux running on Microsoft Surface devices. These days, Linux supports a lot of devices out-of-the-box. As a matter of fact, this includes a good portion of the Microsoft Surface devices—for most parts at least. Unfortunately, Surface devices tend to be a bit special. This is mostly because some hardware choices Microsoft made are rarely (if at all) used by other, more "standard", devices. We aim to send all the changes we make here upstream, but this may take time. This kernel allows us to ship new features faster, as we do not have to adhere to the upstream release schedule (and, for better or worse, code standards). We also rely on it to test and prototype patches before sending them upstream, which is crucial because we maintainers cannot test on all Surface devices (which also means we may break things along the way). -

Linux Kernel
Linux Kernel source tree
The Linux Kernel is the core component of the Linux operating system—a free, open-source, monolithic, Unix-like system kernel initiated by Linus Torvalds in 1991 and since evolved into a foundational technology powering everything from servers and supercomputers to smartphones and embedded devices. There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Extensive filesystem compatibility (ext4, Btrfs, FUSE, XFS, etc.) Broad hardware architecture support (x86, ARM, mainframe, embedded, etc.) -

Linux Test Project
Testsuite to validate the reliability, robustness, stability of Linux.
Linux Test Project (LTP) is a joint project started by SGI, OSDL and Bull developed and maintained by SUSE, Red Hat, Fujitsu, IBM, Cisco, Oracle and others. The project goal is to deliver tests to the open source community that validate reliability, robustness, and stability of the Linux Kernel. The testing suites contain a collection of tools for testing the Linux kernel and related features. Our goal is to improve the Linux kernel and system libraries by bringing test automation.
