Perception

Perception is a hobby operating system. It is a x86-64 operating system built around a microkernel.

The kernel is written in C++. I use a custom build system. I provide a C++ runtime for libraries, services, drivers, and programs. I created an interface descriptor language known as Permebuf.

Features

Very few right now.

• We have a C and C++ standard library for user applications.
• Programs can discover and register Permebuf services and send RPCs to one another.
• We have a tiling window manager (floating windows are also supported!)
• Mounting ISO 9660 disks and reading files.
• Press ESCAPE to open the launcher.

Building and running

See building.md. Perception has only been tested in QEMU. Has a graphical interface and also outputs debugging text via COM1.

Directory Structure

• Applications - Applications/user programs.
• Build - The build system.
• Dump - Code from an old version that will be useful at some point in the future.
• Drivers - Drivers.
• fs - The root file system that is turned into a disk image.
• Libraries - The libraries for building user programs.
• Services - Services and the kernel.
• third_party - 3rd party code I didn't write. They have different licensing.

Repository scope

The scope of this repository is strictly for the core of the operating system. Applications and libraries beyond what would be considered the core of the operating system should live in their own repositories.

Contributing

Being a personal hobby project, I'm not currently accepting other contributors. Feel free to build applications on top of my OS and let me know about them!
