AMD DCN 4.01 Display Core Clock Manager

Internal clock-management code for AMD's fourth-generation Display Core Next (DCN 4.01) display engine, used by recent AMD GPUs to set pixel, display, and memory clock rates needed to drive monitors. It is one piece of the larger amdgpu display pipeline rather than something a user installs or loads independently.

recommendation

This is not actually a standalone driver directory; it is an internal helper component inside the AMD GPU display stack (amdgpu) that programs clocks for the DCN 4.01 display hardware block. It only exists as part of the larger amdgpu driver and cannot be evaluated for keep/remove on its own.

codex reasoning notes (technical)

Not a driver directory: contains DCN401 clock-manager implementation files for the AMD display core, an internal hardware-specific helper subcomponent rather than a standalone kernel driver.
