Sharing common code among subsystems is not a problem. Many of our more-sophisticated helpers are located in DRM because no other subsystems have the requirements yet. Maybe AI now has and we can move the rsp shareable code to a common location. But AI is still no GPU. To give a bad analogy: GPUs transmit audio these days. Yet we don't treat them as sound cards.We actually do, there are full blown sound drivers for them over in sound/ (ok I think they're all in sound/hda for pci gpus or in sound/soc actually). There's some glue to tie it together because it requires coordination between the gpu and sound side of things, but that's it.
I know. But we don't merge both subsystems, just because the devices have some overlap in functionality.

Also I think it would be extremely silly to remove all the drm_ stuff just because it's originated from GPUs, and therefore absolutely cannot be used by other accelarators. I'm not seeing the point in that, but if someone has convincing technical argument for this we could do it. A tree wide s/drm_/xpu_ might make some sense perhaps if that makes people more comfortable with the idea of reusing code from gpu origins for accelerators in general. -Daniel
