Rust OSDev Operating System Development in Rust

This Month in Rust OSDev (October 2021)

Welcome to a new issue of "This Month in Rust OSDev". In these posts, we give a regular overview of notable changes in the Rust operating system development ecosystem.

This series is openly developed on GitHub. Feel free to open pull requests there with content you would like to see in the next issue. If you find some issues on this page, please report them by creating an issue or using our comment form at the bottom of this page.

Project Updates

In this section, we give an overview of notable changes to the projects hosted under the rust-osdev organization.

uefi-rs

The uefi crate provides safe and performant wrappers for UEFI, the successor to the BIOS.

We merged the following PRs this month:

Thanks to @timrobertsdev, @YtvwlD, and @foxcob for their contributions!

acpi

The acpi repository contains crates for parsing the ACPI tables – data structures that the firmware of modern computers use to relay information about the hardware to the OS.

This month, support for the Boot Graphics Resource Table (BGRT) table was added to acpi. This static table is passed from firmware to the OS to communicate information about the state of the screen when control is passed over, as lots of firmwares like to print display a logo when booting. (published as acpi v4.1.0)

Thanks to @ethindp for this contribution!

x86_64

The x86_64 crate provides various abstractions for x86_64 systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.

In October, we merged the following changes:

Thanks to @haraldh and @Freax13 for their contributions!

multiboot2-header (new)

The multiboot2-header crate provides abstraction types for Multiboot2 headers, parsing utilities, and a builder to construct such headers. The initial release took place in early October and now is ready to be used. Because lots of code was published without any in-depth reviews, further testing and code reviews will be highly appreciated.

Personal Projects

In this section, we describe updates to personal projects that are not directly related to the rust-osdev organization. Feel free to create a pull request with the updates of your OS project for the next post.
