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.
In this section, we give an overview of notable changes to the projects hosted under the
uefi crate provides safe and performant wrappers for UEFI, the successor to the BIOS.
We merged the following PRs this month:
- Implement missing Event-related functions
- Remove attribute to enable
- Use build-std-features instead of rlibc
set_virtual_address_map()to allow remapping of
- Fix new clippy errors
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
Thanks to @ethindp for this contribution!
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:
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.

No tasks were proposed for this section.
If you maintain a Rust project related to operating system development and are looking for contributors, especially for tasks suited to people getting started in this space, please create a PR against the
next branch with the tasks you want to include in the next issue.
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.
