  • Unix-like OS in Rust inspired by xv6-riscv
    7 projects | news.ycombinator.com | 25 Jul 2023
    My company, https://www.auxon.io. We created https://github.com/auxoncorp/ferros originally to enable a customer project early in the company's life cycle.

    Some time later we had another customer interested in using it and having us add some features to it (e.g. some device drivers and a persistence layer utilizing https://docs.rs/tickv/latest/tickv/). It was becoming a massive pain in the neck to work out source code sharing agreements with them, so we decided to just open source it.

    There are quite a number of things that we would do differently if we had to build it again, and at some point will likely do that work to revise it. The biggest one of those is root task synthesis. The other is to build and bring in facilities for running tasks that are compiled to WASM.

    When we add WASM support to https://github.com/auxoncorp/ferros it'll sorta be like what you're angling at there in your description.
  • My Fear of Commitment to the First CPU Core

    We've built things on seL4 (https://github.com/auxoncorp/ferros). We like to joke that it's the most perfect piece of nearly featureless software ever made.

    There's... A LOT... of work to do before seL4 is going to be anywhere near usability parity with something like Linux, unfortunately.

    Rather than make a general purpose OS, we decided to use it more like a unikernel or "library OS" where you're trying to make a well defined kind of "appliance" image to deploy to specific hardware rather than try to fake being a POSIX-y shaped OS.

  • FerrOS: Rust-y unikernels on seL4

    For what it's worth, here's FerrOS's repo as well as the underlying selfe repo

    That's basically what we did with https://github.com/auxoncorp/ferros, Bundle Rust programs together as tasks to run atop the formally verified seL4 microkernel.
  • Hubris – An OS from Oxide Computer
    7 projects | news.ycombinator.com | 30 Nov 2021
    We also built a Rust framework called FerrOS (https://github.com/auxoncorp/ferros) atop the formally-verified seL4 microkernel.

    It has a similar set of usage idioms to Hubris it looks like in terms of trying to setup as much as possible ahead of time to assemble what's kind of an application specific operating system where everything your use case needs is assembled at build-time as a bunch of communicating tasks running on seL4.

    We recently added a concise little persistence interface that pulls in TicKV (https://docs.tockos.org/tickv/index.html) from the Tock project you referenced above, and some provisions are being added for some more dynamic task handling based on some asks from an automotive OEM.

  • OSv Unikernel – Optimizing Guest OS to Run Stateless and Serverless Apps
    4 projects | news.ycombinator.com | 9 Oct 2021
    I tried and failed to bring unikernels to my former work when I was at Visa. Specifically, LING.

    At my current company, Auxon, we recently open sourced[1] some work we did a couple years back which is more or less an attempt at the basic foundations for blending the seL4 microkernel with fairly normal no_std Rust application development and assembling them all together to make a purpose built OS/application to deploy directly to hardware or within a VM. We have some work to do to keep building it up as a foundation for broader use, but we're looking into partnering with the seL4 Foundation (now under the Linux Foundation) to iterate on it further with some of our other mutual partners. The developer experience is much closer to that of developing for an RTOS than it is like typical general purpose computing development.

    I'm of course biased, but I think there's a lot of room to innovate in the space of use case specific software stacks where the domain and constraints are well understood and too many degrees of freedom are actually a hindrance and a liability, not an advantage.

  • Open sourced: Easier builds and stronger types for seL4 with Rust
    2 projects | /r/rust | 10 Sep 2021
    On top of that is ferros (no relation to to ferrous-systems), a higher-level userland of unreasonably strong types for compile-time resource tracking. No more discovering you need more memory, or capability slots or IPC rights at runtime. These types help you fit the right seL4 screw to the right seL4 screwdriver.
