AMD DCN 2.1 Display Clock Manager Support Code

Internal helper code inside the AMD GPU display stack that programs clocks for the DCN 2.1 display engine, used by Renoir-era integrated graphics in Ryzen 4000/5000 mobile and desktop APUs from around 2020. It is not a standalone hardware driver but a building block of the larger amdgpu display module.

recommendation

This is not actually a driver directory; it is a sub-component of the amdgpu display core (DC) that handles clock management for the DCN 2.1 display IP block. It only makes sense as part of the larger AMD display driver and would not be evaluated for keep-or-remove on its own.

codex reasoning notes (technical)

Not a driver directory: internal AMD display clock-manager support code for DCN2.1 within amdgpu/display, not a standalone kernel-bound hardware driver.
