The VisionFive 2 developers are working on getting things upstreamed/open-sourced for their board. IIRC the kernel has already mainlined many (if not all) of the patches.

Some of the real issues are as follows:

1) Most companies use Debian as a base. Debian has a notoriously slow release cycle. This means it takes loads of time to submit patches -> get approval -> get merged in a merge window -> wait for debian to use new kernel with new code.

2) The GPU situation is a mess. No decent (compatible) vendors with open source GPU drivers exist. Imagination is said to be working on open source drivers, but with no real release date, we are stuck using closed source blobs. Once drivers and Mesa get updated, we then have to wait for a new release of Debian to pick these up.

3) Far fewer people use these boards over a Raspberry Pi. This means community support takes longer to develop. The VF2 has other distros like Arch and Ubuntu, for example, but no real active community behind them. Last I checked, hardware GPU acceleration was not working in these distros.
