Asterinas: OS kernel written in Rust and providing Linux-compatible ABI

From the README:

> Currently, Asterinas only supports x86-64 VMs. However, our aim for 2024 is to make Asterinas production-ready on x86-64 VMs.

I'm confused.

Yeah, I had to read that a few times... I think they just mean it isn't production ready yet, but that's what they are aiming for.

Sounds like their goal is to improve their x86-64 support before implementing other ISAs.

It's clearer from the book roadmap:

> By 2024, we aim to achieve production-ready status for VM environments on x86-64. > In 2025 and beyond, we will expand our support for CPU architectures and hardware devices.

https://asterinas.github.io/book/kernel/roadmap.html

it would be nice to know how much userspace it supports. supporting the dynamic loader, reasonable futexes, epoll, signals, uring are all big milestones

I think it’s “Currently, Asterinas only supports x86-64 VMs. However, [rather than working on additional architectures this year,] our aim for 2024 is to make Asterinas production-ready on x86-64 VMs.”

Distinction here is between "supports" and "production-ready on", not "x86-64" and "x86-64"
