Not having proper (accelerated) graphics drivers seems to a problem that all alternative OSes suffer from.
Is there any effort addressing that which is flexible enough that say both Haiku and Serenity could use it?
Hasn't Linux had issues with this before? (The famous "fuck you nvidia" Linus meme comes to mind).
Even if they just release all the information required to make one, you still need the labor to write the drivers.
I think what parent is really asking is if there is something like rump kernels[0] for GPU.
[0] is this even a thing anymore? rumpkernel.org seems to have become a generic IT news aggregator.
Because 75% of all public servers are UNIX-like and nowadays by default most commodity computing capacity is on the GPU.
Indeed Linux on the Desktop has been a disaster but that's no reason to make OpenCL and similar efforts a disaster too.
