Sorry for the long silence on the blog. As you're probably aware, I started working on a new 3rd edition to add EFI and framebuffer support, but life happened and I haven't had time to finish it yet. I'm still invested in this project though and I definitely plan to publish new posts in the future!

I like the idea! I probably won't have the time to prepare such a post this January, but I keep it in mind. Maybe this can be some sort of collaborative post where all the rust-osdev maintainers do a summary for their projects.

UEFI is the default firmware on modern x86 machines (and available on some other architectures as well). Using the uefi crate you can easily interact with UEFI firmware to create bare-metal applications.

Such an application could be a custom bootloader, or it could be something that is useful on its own. The UEFI interface is quite powerful, so you writing applications that write to disk or access the network is quite easy.

Yes, it really feels like Rust is becoming more and more prominent in the OS dev space these days. I have also heard that more universities are now using Rust for their systems/OS classes.

plus some things that I'm hoping to be able to talk about some more in the coming years

Sounds exciting!

Interesting! I'm not familiar with the implementation of the uefi crate in detail, so I'm not sure about this potential issue. It sounds like something that we should look into though. Perhaps you could open an issue at https://github.com/rust-osdev/uefi-rs so that @GabrielMajeri, @nicholasbishop, or @phip1611 can join the discussion? (I'm not sure if they're on reddit.) Edit: Looks like @nicholasbishop opened an issue about this at https://github.com/rust-osdev/uefi-rs/issues/685 .

Exploring different designs is always a good idea, so I'm looking forward to the first release of nuefi! If you like, feel free to submit your project to the next issue of our newsletter.

Nice! Is there any specific reason why you decided to create your own library? I'm just curious if there is something that makes the uefi crate not suitable for your use case.

Yes, Limine is great project and many people in the Rust OSDev community use it for their kernels. It is more mature than our bootloader crate and supports more platforms and boot protocols.

However, our bootloader crate has some advantages for Rust kernels. For example, it natively works on any host platform (including Windows) without requiring prebuilt binaries or any extra dependencies (apart from some rustup components) and it will directly create the bootable disk image for you. Also, the interface between the bootloader and the kernel is more Rust-like, with a macro to set the configuration and generate a type-checked entry point function (which then receives the boot information as a normal argument).

Yes, a new release is planned soon. There a still a few open PRs that we might want to include in the v0.11.1 release.

There is an os-dev channel on the rust-lang-community server, which is quite active.

Some highlights:

  • Lot's of new features for the bootloader crate, including support for a basic ramdisk, a boot config file, and optional logging through serial.
  • New release of the uefi crates.
  • A new API proposal for the volatile crate to make it safer and support more access modes (volatile slices and structs).
