Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tilck – A Tiny Linux-Compatible Kernel
> [..] in kernel mode while retaining the ability to compare how the very same usermode bits run on the Linux kernel as well. That's a unique feature in the realm of educational kernels.

Rustaceans at the Border [Linux Kernel]
> How would that work in reality? Re-use the existing tests to build a new kernel from scratch? Sounds like a very far-out idea that wouldn't help with any of the current problems, but I'm happy to entertain the idea and hear your reasoning here.
While I would tend to agree that a full production replacement would be such a massive undertaking as to be impractical, https://github.com/nuta/kerla does something very like that - Linux userspace ABI on an all-new Rust kernel. (And even at this small scale, I find it mind-blowing that this worked)

An OS made from Rust other than Redox
https://github.com/nuta/kerla was mentioned not too long ago - a hobby kernel that aims to reimplement the Linux syscall ABI

OxidOS Automotive
Hi! This is Daniel from OxidOS Automotive (stating this for disclaimer purposes).
Yes, our OS is based on TockOS, and our CEO (Alex Radovici) is #7 in the contributors list (https://github.com/tock/tock/graphs/contributors), with other colleagues contributing in the past years.

Safety vs. Performance. A case study of C, C++ and Rust sort implementations
I'm definitely not the best person to answer this, but honestly it's not bad. Here's an example of a moderately complex peripheral, the cortex-m MPU, and how one rust OS handles it:
https://github.com/tock/tock/blob/3a0527d586702b8ae8cb242391...
Reads and writes turn into volatile reads, so everything works out under the hood. You get the benefits of everything having good names, declared sizes, and proper typing on your register accesses. You can extend that to bit accesses as well.
Rust still has a few areas it isn't competitive in, like your hyper limited or obscure chips (e.g. 8051s, XAP), mature tooling around formal methods, and a certification story for safety critical code. People are working on these latter two issues (e.g. ferrocene) and supposedly very close to public delivery, but you know how slow the industry is to adopt new things even then.

Real-Time Operating Systems 101: Basics for Efficient Computing

Unwinding the Stack the Hard Way
Yeah, and I like I mentioned in the earlier comment, omitting the frame pointer reduces code size by 10% on RISC-V targets, which is huge when dealing with embedded flash: https://github.com/tock/tock/pull/1660

Embedded real time OS
Tock is an excellent embedded OS written in Rust and has some good industrial support. I think Tock gets a lot of stuff right and I highly recommend some of the talks the developers gave on it.

Fedora now has frame pointers
Unfortunately, it increases the code size by 10%. I was looking into this just last week, and can confirm that it's still a problem on the latest version of Rust nightly: https://github.com/tock/tock/pull/1660
I wish we could have frame pointers, because they would make working in embedded land so much easier and more reliable, but a 10% increase in code size just isn't worth it.

Rust OS
TockOS was the first rust RTOS I found. Coincidentally, it has had support for the esp32c3 for over a year now.
