Sooo... How open is this board? The core designs are XuanTie, which is open / royalty free. What about the GPU? Are any schematics or data sheets posted for the board? Design files?

> Are any schematics or data sheets posted for the board? Design files? Agree. And some VHDL / Verilog while we're at it.

  Here you go: https://github.com/T-head-Semi/openc910 https://github.com/T-head-Semi/openc910 (This isn't doesn't include the draft vector extension present in the C910)

    Hmm but this is just the CPU core. Not the whole SoC or board...

Afaik TH1520 SoC includes an Imagination BXM-4-64 gpu: https://www.imaginationtech.com/products/gpu/img-b-series-gpu/ https://www.imaginationtech.com/products/gpu/img-b-series-gp... They appear open source friendly, but both this gpu & SoC being fairly recent, we'll have to wait & see how this goes. GPU design itself is closed, like for practically any other (modern) gpu. No doubt this board will have many applications. With this powerful cpu+gpu, desktop replacement could be among those. But lack of regular USB connectors (or external hub required) is a big drawback. Also I prefer RPi style gpio header. But that's just me.
