AMD DCN 3.01 Display I/O sub-block

A small piece of the AMD Display Core code inside the amdgpu graphics stack, covering the display input/output block specific to DCN 3.01 hardware (used by Van Gogh APUs that power devices like the Steam Deck, circa 2021). It handles encoder and link wiring for that GPU generation as part of the larger display pipeline.

recommendation

This is not actually a standalone driver; it is an internal sub-component of the AMD Display Core inside the amdgpu driver. It only makes sense as part of that larger stack and is not separately loadable or removable.

codex reasoning notes (technical)

Not a driver directory: AMD DCN301 display I/O sub-block implementation inside the amdgpu/display stack, not a standalone kernel-bound hardware driver.
