So I'm unfamiliar with this so let me ask a few dumb questions but first of all great job! My questions are - If you didn't do this work how would you use this soc? When I search, it is stated that it supports OpenGL and Vulkan but was that just ' in theory? ' How can a SOC developer make a product without driver support? Don't they risk messing up and having hardware that doesn't work properly?
The GPU driver itself is largely the same, though it might need some tweaks for the specific variant in the K1.
The bigger hurdle will likely be the display controller. The TH1520 and JH7110 both use the Verisilicon DC8200, whereas the Spacemit K1 uses a custom display controller that will need its own DRM driver mainlined.
The Orange Pi RV2 (Ky X1) uses the Imagination BXE-2-32.
The good news is that firmware is available for that variant. The bad news is that Mesa currently lists the BXE-2-32 as 'unsupported / not under active development' (unlike the BXS-4-64 in the TH1520, which is active).

So while the kernel driver (drm/imagination) is the right path, the RV2 is a steeper hill to climb: it needs the SoC kernel plumbing and likely some work in Mesa.
I agree DisplayPort would be nice, but unfortunately, almost all currently available RISC-V SBCs only have physical HDMI and MIPI DSI connectors. We have to support the hardware that actually exists on the board.

BTW is OrangePI V2 supported?

I will have to wait then. I may choose a supported variant then.
K3 (which succeeds K1 this story is about) is expected to be among them.
just let this worse standard die already - and switch to DisplayPort
