multiboot2
Rust library that helps you to parse the multiboot information structure (mbi) from
Multiboot2-compliant bootloaders, like GRUB. It supports all tags from the specification
including full support for the sections of ELF-64 files. This library is no_std
and can be
used in a Multiboot2-kernel.
It follows the Multiboot 2.0 specification at https://www.gnu.org/software/grub/manual/multiboot2/multiboot.html and the ELF 64 specification at http://www.uclibc.org/docs/elf-64-gen.pdf.
Background: The Multiboot 2 Information Structure
The Multiboot information structure looks like this:
Field | Type |
---|---|
total size | u32 |
reserved | u32 |
tags | variable |
end tag = (0, 8) | (u32, u32) |
There are many different types of tags, but they all have the same beginning:
Field | Type |
---|---|
type | u32 |
size | u32 |
other fields | variable |
All tags and the mbi itself are 8-byte aligned. The last tag must be the end tag, which is a tag of type 0
and size 8
.
MSRV
The MSRV is 1.56.1 stable.
