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.

Features

A x86-64 native microkernel.
Full C/C++ standard library support.
Processes can discover and register services and send RPCs to one another.
Mounting ISO 9660 disks and reading files.
Basic hardware support (PS/2 keyboard, IDE storage, Multiboot framebuffer and Virtio graphics, Virtio network).
A window manager, custom C++ UI framework, and an interactive UI debugger.
Launching userland applications.
There's a permissions system (e.g. "Allow File Manger to launch applications?") and a registry with an editor.
Some simple applications like File Manager, Calculator, and Image Viewer.
Some simple games (2048, Minesweeper, Snake).

Building and running

See building.md. Perception has only been tested in QEMU. It outputs debugging text via COM1.

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!
