The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

My RISC-V OSDev journey, so far
How to automate building and running the project using make; in particular, leveraging variables in the Makefile to elegantly apply the same command line options for compiling each file in the codebase - because trust me, you'll need a ton of command-line options ;-) For this, I based my initial Makefile on that found in the source code for "The Adventures of OS", e.g. this

Getting started with OSDev on RISC-V
I would like to thank the authors of RISC-V from scratch and The Adventures of OS for their high-quality articles that go into great detail on how RISC-V works. Without their well-written articles, I wouldn't have known how to get started with kernel development on RISC-V. My initial project setup - the minimal C runtime crt0.s in assembly and the linker script riscv64-virt.lds - is based on the former, while my UART driver code is adapted from the latter and I intend to closely follow the latter going forward.

RV32I Stack and stack pointer in hardware implementation
Here's an example of an interrupt routine (m_trap_vector): https://github.com/sgmarz/osblog/blob/master/risc_v/src/asm/trap.S

rustc + avr = lovelove back again!
Also note that some libraries in the ecosystem might still use a feature called llvm_asm that was removed from rustc in 2021, so those crates might need a while to migrate to the newer asm syntax (this feature is used to provide an inline AVR assembly, e.g. to implement a cycle-accurate delay); so far I've got patches merged to https://github.com/Rahix/avr-hal & https://github.com/Rahix/avr-device :-)

Rust for microcontrollers question
Take a look at the avr-device crate, it also explains how to add a new controller and how to get to the svd files.
What are some alternatives?
When comparing osblog and avr-device you can also consider the following projects:
riscv-elf-psabi-doc - A RISC-V ELF psABI Document
rustsbi - RISC-V Supervisor Binary Interface (RISC-V SBI) library in Rust; runs on M or HS mode; good support for embedded Rust ecosystem. For binary download see prototyper folder.
