A simple barebones 64-bit higher-half kernel for x86_64. At least it works.

Last time I posted here, I was showing off kmscon running on Managarm. While terminal emulators, editors, and all that are good to have, they're boring. Managarm offered nothing to entertain, until recently. We ported SDL2, which opened many possibilities for porting games and such. Initially it only worked under the KMSDRM video target, but yesterday I got it working under Wayland. I first wanted to port DOOM, but I couldn't decide on the source port to use, so we ported tyr-quake instead. After finishing the porting, we decided to do something about the poor graphics performance and worked on finishing the LLVM port and compiling Mesa with the llvmpipe driver instead of the slow softpipe driver. After VVVVVV was open-sourced it also got ported (Serenity OS beat us by a day or two though :^) ).

The picture shows both the VVVVVV port and the tyr-quake port running at once with good performance, on a VM with a single core.

VVVVVV is absolutely not open source.

You are right, I did use the wrong term. By open-sourced I meant the source being released under a license that would allow us to port it.

Here's a very primitive kernel of ExpOS, made on a virtual machine running Windows XP SP3 and Bochs 2.6.10,
A lot of functions are to be implemented soon.

Last week I've been working on a slab allocator heap and integrating a wasm compiler (Cranelift) inside my kernel.
This is a simple wasm program executing and writing a fibonacci value to its memory slice, then the kernel reads it to verify.

Your OS seems quite impressive due to the fact that you implemented an advanced GUI. Looks awesome!

That's absolutely amazing. It looks like a modern UI mockup, not a real GUI running on a hobby OS. Superb work!

Managarm running mednafen. Most of the work was done by qookie (including the pthread implementation). I focus more on core improvements right now.

I can imagine few things more awesome than this (in the original sense: awe-inspiring). Good work!

I recently got back into osdev. I've started again from scratch and this time I'm doing it the right way ( = what I said before my previous attempt). I've completed most of the work on my bootloader, this time it actually does all the things you'd expect from it so that the kernel, when I have a kernel, can be completely agnostic of the firmware. It even has menu's! Some pics of it running on real hardware:

@sleephacker: Sweet! But is the kernel really <= 4096 bytes? $b000 - $a000 = 4096.
