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.

Needing advice on creating short delays mostly in C
I'm sorry, but bit banging WS2812 on that hardware is stupid. Find some peripheral that you can use to output WS2812 bitstreams, and use that. For example, for the Raspberry Pi there is a library at https://github.com/jgarff/rpi_ws281x that can use either PWM, PCM or SPI to do this. I know you're dealing with a different CPU, but this should give you ideas about how you can use its peripherals. The data sheet is available: https://github.com/milkv-duo/duo-files/blob/main/hardware/CV1800B/CV1800B-CV1801B-Preliminary-Datasheet-full-en.pdf
- The Milk-V Duo full preliminary English datasheet just dropped on GitHub
- Milk-V Duo received today from Aliexpress :)

Milk-V Duo: A $9 RISC-V COMPUTER
Datasheet: https://github.com/milkv-duo/hardware
Reading the datasheet, it looks like there is one C906 cpu with 700 Mhz without the the vector extension and one C906 cpu at 1Ghz with rvv 0.7.1. The C906 design has been opensourced and is available here: https://github.com/T-head-Semi/openc906
The C906 supports rv64gc with optimal rvv 0.7.1 with a vlen of 128, but a 256 wide ALU.
They list H.264/H.265 support, but I don't think it's a standardized extension.
But see my other comment about using the pre ratification vector extension:

Milk-V Duo: A $9 RISC-V COMPUTER
It has hardware IRQ muxing, this is the driver (https://github.com/smaeul/linux/commit/16eafe2078ebe9306d095...), we already use if for booting off sdcard/ethernet/usb etc..

Linux kernel hangs on Nezha board after enabling additional configs
I was able to compile the default Linux kernel (from https://github.com/smaeul/linux) and boot it on Nezha board.

Nezha board not booting up with updated Linux kernel
Cloned and built the linux kernel with defconfig from https://github.com/smaeul/linux/tree/d1/all. Used riscv64-linux-gnu-gcc 9.4.0 that I installed using apt on Ubuntu for cross compiling.

Can the RISC-V Nezha board with Allwinner D1 run upstream Linux kernel?
I saw some instructions are available to build the Linux kernel for D1 at https://linux-sunxi.org/Allwinner_Nezha and https://andreas.welcomes-you.com/boot-sw-debian-risc-v-lichee-rv/ but they use a custom Linux source at https://github.com/smaeul/linux

Debian on Devterm R-01
I got about as far as before your first edit, but gave up before trying. It's cool that you found the fork point. Looks like quite a lot of work to unpick. Did you see the https://github.com/smaeul/linux/commits/riscv/d1-wip in the other thread, also seems worth looking at.
What are some alternatives?
