AMD DCN 2.0 HUBBUB display pipeline component

A small internal building block of AMD's Display Core (DC) code inside the amdgpu graphics driver, covering the HUBBUB memory-request block of the DCN 2.0 display pipeline used by Navi-generation Radeon GPUs (RX 5000 series, around 2019).

recommendation

This is not a standalone driver but a subdirectory of helper code that the main amdgpu/DC driver compiles in to drive one specific hardware block of the DCN 2.0 display engine. It has no independent lifecycle of its own and lives or dies with the larger AMD display stack.

codex reasoning notes (technical)

Not a driver directory: DCN2.0 hubbub display-pipeline subcomponent under amdgpu DC, not a standalone kernel-bound hardware driver.
