Hey guys!
Sam and I have been hard at work at releasing our source code for the Project Sparrow work we've been working on for the last year or so, and we just managed to get our first release up at < https://github.com/AmbiML/sparrow-manifest%3E. So, we thought we'd announce it to the devel list!
A bit of background: Sparrow is a project to build an open source low-power secure embedded platform for Ambient ML applications. Our target platform leverages RISC-V and OpenTitan, and all our contributions are licensed under the Apache-2 open source license.
The Sparrow software includes a home-grown operating system named KataOS, that runs on top of seL4 and is written almost entirely in Rust.
We’ve pushed some foundational pieces of KataOS to GitHub together with build glue to run seL4 CAmkES test applications on a 64-bit ARM platform (running in simulation on qemu). These are intended to show the direction we’re headed and enable anyone to start building their own systems in Rust on top of seL4.
This initial tranche of code includes: frameworks (e.g. the sel4-sys crate that provides seL4 syscall apis), an alternate rootserver (needed for dynamic system-wide memory management), and the kernel modifications that enable reclaiming the memory used by the rootserver.
This push does not, as yet, include the CAmkES services that support dynamic loading+running of applications–that will be published as we deem it ready for sharing until eventually all of Sparrow (software and hardware designs) will be available.
While we are developing for an experimental 32-bit RISC-V platform, we intend to push code that runs on aarch64 platforms. Help is welcome to make the code base run on more platforms.
In the long run, we're planning on opening up everything we can, so please watch this space!
