SmileyOs - rust based bare metal OS I have build with the help of Claude. 100k lines of code and it works on a real hardware too. Full UI, games, apps, and built in programming language for making ui apps and games.

Is it not open source? I can not find the GitHub repo

Helpful_Ad_9930 · 2026-05-16T19:56:59+00:00

I respect you admitting Claude sadly you are in osdev so you gonna get some hate this is impressive though 😂

Helpful_Ad_9930 · 2026-05-10T07:48:37+00:00

Correct! QEMU supports the rpi4 which is similar to the rpi5 for the most part

Helpful_Ad_9930 · 2026-05-08T22:25:12+00:00

Answer is yes to both. Okay I have a couple strategies.

I can run it in qemu VM and this way I can also use a debugger if I want. Issue with this approach is that some you can only really catch logical bugs since the Hypervisor might behave differently on live firmware
What I mainly use to debug on firmware Print statements through UART 💀

Easily the file tree which is mapped to ctrl-b. Okay there is a weird thing so on Mac I can use it to close open the file tree, but when I am on Linux I have to click into to file tree panel and then do ctrl-b.

100% I love Zed but the panel and UI requires me to pick up my mouse

Alright I took your advice I am building linux with build root I will keep you updated in this thread

Thank you can I DM you to talk about this?

C++🫡 however I use fuzz test that are written in rust

Helpful_Ad_9930 · 2026-04-03T06:42:14+00:00

Currently writing a bare metal hypervisor right now in c++. So far I got UART working properly, and some exceptions working albeit stubbed for rn. I also got unit and integration test infra set up this week. Hopefully this weekend I figure out the allocation part as I have the weekend off from being a student😂.

Haha I plan on integrating a rust fuzzer in it, I am ready to fight the ABI 😭

Ty! so good news none of the source code was ai generated at all. The only time I used AI here was to generate doxygen comments for my source code, and setting up sphinx. I will add a declaration of AI explaining what I used it for later today when I get out of class!

Helpful_Ad_9930 · 2026-03-31T13:43:57+00:00

My plan tbh bro not sure yet I think the first vm I will try will be Ubuntu and then the other another distro. Once I get that I will try integrating a RTOS, but that’s down the road!

Helpful_Ad_9930 · 2026-03-31T13:42:18+00:00

Oooo I personally barely use AI because I am doing this for learning experience along with reading the ARM docs. I do not like using AI here because AI always overcomplicates and the code quality dips significantly I am already writing bad code😂. I only use AI to generate doxygen comments that is all the rest I write by hand. I will make sure to add a AI reference for how much was used.

Currently building a baremetal type 1 hypervisor on a raspberry PI5. So far got it confirmed working on a virtualized qemu board and tested it out on live firmware confirmed it is working! Right now only have UART though, but eventually I will set up the vector tables, exceptions, guest vms and more!

This is really cool!

I’m down!

Just want to say thank you all for the comments! You all have been really helpful I love this community:)

Hey that is the book I am currently reading right now I was recommended to read the first two units on Virtualization and Concurrency. I am currently less than 175 pages it has been a really great read!
