recommendation

This is not actually a driver directory; it is a collection of internal protocol helper modules that live inside the AMD Display Core code shared by the amdgpu graphics driver. It has no independent existence as a loadable driver and is maintained as part of the broader AMD GPU display stack.

codex reasoning notes (technical)

Not a driver directory: contains AMD display-link protocol helper code within the DC stack, not a standalone kernel-bound hardware driver.
