limine VS toaruos

I assume this person meant to say `Limine'.

It's what I use for dualbooting Windows and Linux. It's really easy to Install, Use & Understand.

https://limine-bootloader.org/

They also publish a PHILOSOPHY.md page in their MS-source-git (github) that is, which is clearly offensive to us and many linux users:

I'm using Limine for bootloader, and in its documentation, in the Protocol page, we have:

Hello! While reading the Limine protocol specification i noticed that it says that "all non-usable entries (including kernel/modules) are not guaranteed any alignment, nor is it guaranteed that they do not overlap other entries". How am I supposed to get the memory size then? If the memory map entries can overlap, then summing their lengths won't work. Any help is appreciated, thanks in advance.

That's the Limine bootloader

It's way easier to use a pre-existing bootloader. I recommend Limine. It has it's own boot protocol that's designed for x86_64. You don't need any additional setup as it's already booted to long mode unlike Multiboot which needs you to switch to long mode since it's booted in protected mode. You can find an example kernel here.

It uses Limine as the Bootloader but I used Ponchos OS Dev Playlist as a base.

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.
