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.

Writing an OS in Rust to run on RISC-V
Xous, the OS that runs on the precursor, may be of interest to look at too:
https://github.com/betrusted-io/xous-core
It is written in Rust and is targeted for a RISC-V

Is there any reliable guide for creating an operating system in Rust?
In addition to phil-opp and redox, there's the Betrusted project's Xous kernel, which runs on a RISC-V core that runs on an FPGA. There's even an Xous Book.

Another Vulnerability in the LPC55S69 ROM
You might be interested in Precursor and the Betrusted Platform.
https://www.crowdsupply.com/sutajio-kosagi/precursor
They are trying to have an hardware platform that can be inspected and it is based on an FPGA with a RISC-V Softcore.
Its by Bunnie, and he great talks about the choices and why he made them:
Keynote: Precursor - Trustable Open Hardware for Everyday Use - Bunnie Huang (https://www.youtube.com/watch?v=Fw5FEuGRrLE)
They are also doing their own Rust Message passing OS called Xous that might be of interest.

Kerla: Monolithic kernel in Rust, aiming for Linux ABI compatibility
There are more good efforts, the BeTrusted guys are working on Xous, its a microkernel for a phone like device called the Precurser.
https://github.com/betrusted-io/xous-core
As a embedded service processor OS for a big server rack, Oxide Computer is working on 'HubrisOS'. They seem to have not released it yet, but that will be open sourced.
https://github.com/oxidecomputer
Those are two efforts where I know real resources are going into.
