AMD DCN 4.0.1 Display Hubbub Subcomponent

Internal support code for the "hubbub" memory-request arbitration block inside AMD's DCN 4.0.1 display controller, which is the display engine paired with the latest AMD GPUs. It is one piece of AMD's larger display core library rather than a hardware driver in its own right.

recommendation

This is not actually a driver directory; it is an internal building block of the AMD display core (DCN 4.0.1) used by the larger amdgpu graphics driver. It implements the hubbub memory-arbitration logic for AMD's newest display pipeline generation and only ships as part of amdgpu, not as a standalone module.

codex reasoning notes (technical)

Not a driver directory: contains AMD DCN4.0.1 display-pipeline hubbub block support code, an internal DRM/AMDGPU subcomponent rather than a standalone kernel-bound hardware driver.
