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.

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"

They lack essential things for a kernel that could be used in production, viz. not kernel panicing during out-of-memory conditions, not an easy thing to retrofit when you have designed without consideration of it. It will probably take a bit more than 2 and a half months to rectify that.

They've been working on it for a while so they can get rust into the linux kernel
