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.

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.

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
