It's just a prototype windowing environment, very early days. However, I think you can see the inspiration (MacOS system 1 and the like). The grey rectangles up top are font characters. I have pixel font rendering but no font yet haha.

That looks great Am I right in thinking that the name implies you are writing in .NET? That would be rather fascinating.

Yeah. im using .NET and this is what the OS look like now

I just renamed it because it reminds of SharpOS. they are totally different things

Managarm (repo link) can now run sway, including X apps via xwayland. See for yourself:



Edit: I should mention that this is not upstreamed yet. Feel free to check out the PRs, though!

Hello everyone, this months brought lots of improvements to the entire system, we now have fully higher half kernel support, Drivers loaded as kernel-mode module (dll files), Dynamic libraries for user mode processes (dll files), PCI-Express with MSI support, SMP support, SSE/SSE2 support, networking & sound support with Intel HD Audio as hardware sound card.

Here's an image of window compositor with true type font ("Roboto").

I'm currently working on a tiling window manager. It is far from being finished but I'd like to show off what I have already




The WM uses a binary tree to determine how to size each window. Each parent node has a 16-bit ratio (from 0 to 1 inclusive) to determine how many pixels high or wide each child may be. The border is simply a fixed amount of pixels substracted from the final size. It also automatically determines whether to split horizontally or vertically such that the windows have an aspect ratio that is as close to 1 as possible. I do intend to make it possible to resize & move windows though, of course.

I'm using fontdue for rendering the characters. It is simple to use and seems to work very well. I had to implement support for SSE2 though since LLVM seems to use SSE instructions in intrinsics regardless of the soft-float feature but it turned out to be quite easy (though I mistakenly aligned the stack after a call instead of before, that was quite a headscratcher).

Looks neat!


What about -mgeneral-regs-only?

AFAICT it only adds these options: -target-feature -x87 -target-feature -mmx -target-feature -sse

Given that I already specified -sse and -mmx (and the Rust compiler doesn't seem to have a direct equivalent to -mgeneral-regs-only) it probably wouldn't help.

After some fiddling around I got my kernel to boot and work on real hardware!

Cool! Are you aiming for POSIX compliance?

Yup! That's what I was aiming for. Although now I'm rewriting the kernel from the ground up because I had made some design mistakes, and also because I want it to better use modern hardware (it ran in protected mode, for example).

Working on the spiritual successor to my previous OS. This one combines my other pet project, the Stage programming language, with an OS: StageOS. Still pretty early on, but yeah. The message in the Kernel window is loaded from the filesystem (FAT16) at the moment.

It took me a while but I finally got a sort-of working GUI!
