kush-os VS toaruos

It’s very much doable; I did exactly this with an OS I worked on last year. This takes advantage of many modern C++20 features, most of which work just fine in a bare metal environment. As others have said, you’ll have to disable runtime features like exceptions and RTTI in your kernel. A lot of it is really hacky, but this was just meant to be a proof of concept project that got a little out of hand :)

I’ve written an AHCI driver for my OS which I’ve tested works on a few VM platforms and real hardware. I’m not actively working on this project anymore due to my current job, but maybe it can be a useful reference for you.

Another interesting project to checkout is klange’s toaruos https://github.com/klange/toaruos

In case it's not clear, PonyOS is a joke reskin of my serious OS project, ToaruOS. PonyOS gets a new release every April 1st. All of the libraries and applications in ToaruOS are in-house things I built myself - the whole OS is "built from scratch". PonyOS adds ponysay, which is an external app originally written in Python - and in previous releases of PonyOS I shipped the Python version alongside a port of Python 3.6. This release, though, comes with a port to my own language, Kuroko, which is a dialect of Python - a lot of what went into building the PonyOS release this year was getting ponysay to work well.

There is no correct way to use inline assembly here. You need a stub written in assembly that will save those registers to the stack and pass a pointer to a handler written in C. You may also want to define a struct that matches the stack layout to make it easier to access the stack contents. This is not my code. If you want to use this code in your OS, you must follow the license requirements.

Here's a good example, although it's 64-bit instead of 32-bit.
