Announcements, News, and Blog Posts

Here we collect news, blog posts, etc. related to OS development in Rust.

Infrastructure and Tooling

In this section, we collect recent updates to rustc, cargo, and other tooling that are relevant to Rust OS development.

rust-osdev Projects

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

acpi

Maintained by @IsaacWoods

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. We merged the following changes this month:

Thanks to @fslongjin and @rw-vanc for their contributions!

x86_64

Maintained by @phil-opp, @josephlr, and @Freax13

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.

We merged the following PRs this month:

Thanks to @uglyoldbob, @GZTimeWalker, and @Sxmourai for their contributions!

bootloader

Maintained by @phil-opp and @Freax13

The bootloader crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. This month, we merged the following improvements:

Thanks to @nicholasbishop, and @Freax13 for their contributions!

ucs2-rs

Maintained by @GabrielMajeri, @nicholasbishop, and @phip1611

pic8259

Maintained by @phil-opp

The pic_8259 crate provides abstractions for 8259 and 8259A Programmable Interrupt Controllers (PICs).

We merged the following PR this month:

Thanks to @iTitus for their contribution!

ovmf-prebuilt

Maintained by @phil-opp and @nicholasbishop

The ovmf-prebuilt project provides pre-built edk2 releases to make it easier to set up OVMF. We merged the following improvement this month:

volatile

Maintained by @phil-opp

The volatile crate provides a safe wrapper type for implementing volatile read and write operations. This is useful for accessing memory regions that have side-effects, such as memory-mapped hardware registers.

We merged the following PRs this month:

Thanks to @nspin and @kadiwa4 for their contributions!

linked-list-allocator

Maintained by @phil-opp and @jamesmunns

The linked-list-allocator crate provides a basic no_std allocator that builds a linked list from freed memory blocks and thus needs no additional data structures. We merged the following PR this month:

uefi-rs

Maintained by @GabrielMajeri, @nicholasbishop, and @phip1611

The uefi-rs crate provides safe and performant wrappers for UEFI, the successor to the BIOS. We merged the following PRs this month:

Other Projects

In this section, we describe updates to Rust OS 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.

No projects updates were submitted this month.
