<span class="maintainers">Maintained by [@phil-opp](https://github.com/phil-opp)</span>

The `bootimage` tool allows the creation of bootable disk images for `bootloader`-based kernels. It also provides a runner executable for `cargo` to make `cargo run` and `cargo test` work using QEMU.

We merged the following changes this month:

- [Add an example kernel that uses the built-in `x86_64-unknown-none` target](https://github.com/rust-osdev/bootimage/pull/104)

### [`acpi`](https://github.com/rust-osdev/acpi)
<span class="maintainers">Maintained by [@IsaacWoods](https://github.com/IsaacWoods)</span>

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:

- [Add support for extracting NUMA information from SRAT and SLIT](https://github.com/rust-osdev/acpi/pull/264)

Thanks to [@martin-hughes](https://github.com/martin-hughes) for their contributions!


### [`endian-num`](https://github.com/rust-osdev/endian-num)
<span class="maintainers">Maintained by [@mkroening](https://github.com/mkroening)</span>

The `endian-num` crate provides the `Be` (big-endian) and `Le` (little-endian) byte-order-aware numeric types.

- [feat: add MSRV of 1.71](https://github.com/rust-osdev/endian-num/pull/7)
- [fix(docsrs): migrate from `doc_auto_cfg` to `doc_cfg`](https://github.com/rust-osdev/endian-num/pull/6)


### [`fuse-abi`](https://github.com/rust-osdev/fuse-abi)
<span class="maintainers">Maintained by [@mkroening](https://github.com/mkroening)</span>

The `fuse-abi` crate provides bindings to FUSE devices. In motivation similar to that of `virtio-spec`, this project aims to provide correct foundational definitions for the FUSE kernel ABI.

We merged the following changes this month:

- [fix(docsrs): migrate from `doc_auto_cfg` to `doc_cfg`](https://github.com/rust-osdev/fuse-abi/pull/1)

<!-- - [chore: upgrade bindgen-cli to 0.72.1](https://github.com/rust-osdev/fuse-abi/pull/2) -->


### [`spinning_top`](https://github.com/rust-osdev/spinning_top)
<span class="maintainers">Maintained by [@phil-opp](https://github.com/phil-opp)</span>

The `spinning_top` crate provides a simple spinlock implementation based on the abstractions of the [`lock_api`](https://docs.rs/lock_api/0.4.1/lock_api/) crate.

We merged the following changes this month:

- [fix(docsrs): migrate from `doc_auto_cfg` to `doc_cfg`](https://github.com/rust-osdev/spinning_top/pull/27)


## 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](https://github.com/rust-osdev/homepage/pulls) with the updates of your OS project for the next post.

<!--
Please use the following template:

### [`owner_name/repo_name`](https://github.com/rust-osdev/owner_name/repo_name)
<span class="maintainers">(Section written by [@your_github_name](https://github.com/your_github_name))</span>

...<<your project updates>>...
-->

### [`metta-systems/ram-map-viewer`](https://github.com/metta-systems/ram-map-viewer)
<span class="maintainers">(Section written by [@berkus](https://github.com/berkus))</span>

Added a little GUI for visualizing memory maps. The application itself currently supports a map format that my initialisation code emits, but
it has a MemorySource trait that you can implement to consume any format.

<video src="https://raw.githubusercontent.com/metta-systems/ram-map-viewer/video/video/ram-map-viewer.mp4" controls></video>

### [`metta-systems/vesper`](https://github.com/metta-systems/vesper)
<span class="maintainers">(Section written by [@berkus](https://github.com/berkus))</span>

Vesper has learned to put nucleus into higher-half memory and added a kernel syscall API with a single syscall - a capability invocation. I have a list of capabilities I want to implement, and first one implemented is Debug Console so you can output execution trace from your domains.

Init thread implementation in progress, now parsing DTB and preparing to launch a user-space "init" process. The video above shows memory map produced by the init thread after parsing a RasPi3 B+ 1Gb DTB.
