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.

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
There's Tock (https://www.tockos.org/), which is written in Rust (with sprinkles of assembly).

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.

Fomos: Experimental OS, Built with Rust
Theseus OS (https://www.theseus-os.com/) is also an OS written in Rust. It's a safe-language OS and I believe it's the future of the OSes due to its unique features.

Asynchronous Rust on Cortex-M Microcontrollers
I believe that Tock (tockos.org) and Theseus (https://github.com/theseus-os/Theseus) are in this area a bit as well, just from an actual OS perspective.
I don't know much about this area, but it would be wonderful if these could work with the Libre compute boards, like the AM Logic S905X (Lepotato) or the Rock chip, since they're so much cheaper than a Pi.

Making a RISC-V Operating System Using Rust
Relevant, also an OS written in and made possible by Rust: https://www.theseus-os.com/
I think Theseus is to conventional OSes what Rust is to JavaScript.

Microsoft is busy rewriting core Windows library code in memory-safe Rust
I wonder if somehow someday Microsoft Windows can be rerooted as something like wine running in user space of a rust os like https://github.com/theseus-os/Theseus

Need help for porting my kernel to different architectures.
We've been working on porting Theseus OS to aarch64 over the past few months, feel free to browse our code if you need help understanding anything. Theseus is written from scratch entirely in Rust, so it's likely quite relevant to your work. You can probably find all of the aarch64-related commits and issues just by searching "aarch64" on the repo.

Exploiting null-dereferences in the Linux kernel
I mean, there are several rust kernel/os projects in progress.
One project that's pushing on the boundary of safety and composability is Thesus, which takes language safety to new ground by shifting traditionally OS-level responsibilities like resource management all the way down to typechecks in the language, and also explores a way of updating any core OS component on a live running system. https://github.com/theseus-os/Theseus
There's also KataOS which google just recently announced: https://opensource.googleblog.com/2022/10/announcing-kataos-...
As you note, these things take time, I agree with sibling that none of them are likely to be "enterprise-grade" or "production ready" this decade.
