AMD DCN 4.01 Display I/O Helpers

Internal helper code inside AMD's Display Core component of the amdgpu graphics driver, specifically for the Display I/O block of the DCN 4.01 generation used in recent Radeon and Ryzen GPUs. It handles low-level encoder and output configuration rather than functioning as a standalone driver.

recommendation

This is not actually a driver directory; it is a sub-component of AMD's larger amdgpu display stack. It only makes sense as part of the full Display Core tree and cannot be evaluated for keep/remove independently of amdgpu as a whole.

codex reasoning notes (technical)

Not a driver directory: internal AMD DC display-core DIO/DCN401 helper subdirectory within amdgpu, not a standalone kernel-bound hardware driver.
