limine VS x86_64

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.

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.

Yes, while it may seem on the surface like the blog hasn't been updated in a while, the whole rust x86 project is under active development:

See here

I see - looking at the source code of x86_64 library, I noticed that:https://github.com/rust-osdev/x86_64/blob/master/src/structures/idt.rs#L516What does that line do? I don't know Rust, but it feels like it repeats the first 32 IDT entries (which are for exceptions) for rest of the IDT.
