QP Real-Time Event Frameworks & Tools
Real-Time Event Frameworks based on active objects & state machines
QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows. -

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. -

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. -

stress-ng
This is the stress-ng upstream project git repository.
This is the stress-ng upstream project git repository. stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces. stress-ng was originally intended to make a machine work hard and trip hardware issues such as thermal overruns as well as operating system bugs that only occur when a system is being thrashed hard. Use stress-ng with caution as some of the tests can make a system run hot on poorly designed hardware and also can cause excessive system thrashing which may be difficult to stop. -

ToaruOS
Hobby operating system, bootloader, kernel, drivers, C library
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. -
