AMD DCN 4.01 HUBP display pipeline helpers

Internal helper code for the Hub Pipe (HUBP) block of AMD's Display Core Next 4.01 hardware, used by recent Radeon and Ryzen integrated GPUs to fetch pixel data from memory into the display pipeline. It is one piece of the larger amdgpu display stack rather than something users load on its own.

recommendation

This is not actually a standalone driver directory; it is a sub-component of AMD's amdgpu display core (DCN 4.01 generation) that handles a specific stage of the display pipeline. It only makes sense as part of the wider amdgpu graphics driver and should be evaluated in that context, not on its own.

codex reasoning notes (technical)

Not a driver directory: internal AMD DCN 4.01 HUBP display-pipeline helper block within the amdgpu display stack, not a standalone kernel-bound hardware driver.
