AMD DCN 3.2 HUBP display pipeline support code

Internal building-block code for the Hub Pipe (HUBP) component of AMD's Display Core Next 3.2 hardware, which is the display engine found in RDNA 3 era Radeon GPUs and APUs (Navi 3x, roughly 2022 onward). HUBP is the block that fetches pixel data from memory and feeds it into the display pipeline.

recommendation

This is not actually a standalone driver; it is one small piece of the much larger amdgpu display stack, providing DCN 3.2 specific HUBP routines that get linked into the main AMD GPU driver. It only makes sense to evaluate the amdgpu/DC subsystem as a whole, not this subdirectory in isolation.

codex reasoning notes (technical)

Not a driver directory: contains AMD DCN3.2 HUBP display-pipeline block support code within the amdgpu/display stack, not a standalone kernel-bound hardware driver.
