My microkernel-based OS built from scratch now has basic Unix commands
This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root…
In plain words
This is a from-scratch microkernel-based operating system with no code inherited from existing systems. It includes a pure microkernel handling multiprocessor scheduling, memory management, and interprocess communication, along with a partial C library and driver servers for keyboards, NVMe SSDs, and Unix-like file systems. Built for OS research and design exploration, the project aims to address microkernel performance limitations while developing a general-purpose Unix-like system suitable for real hardware.

In the maker’s words, at launch
This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root mountpoint, /dev, /proc, etc.) and several other necessities. The main goal of this project is to research OS design and try to overcome some of the performance penalties associated with microkernels, while also building a general-purpose usable Unix-like OS on top of it. It's also intended to make the study of OS development and theory a little more approachable through self-documenting, clean, and readable modular code.
