AMDGPU DCN 4.2 Display Power-Gating Support Code

Internal helper code within AMD's Display Core that manages power-gating sequences for the DCN 4.2 display hardware block found in recent AMD GPUs and APUs. It is one piece of the larger amdgpu graphics stack, not a separately loadable driver.

recommendation

This is not actually a driver directory; it is a small piece of internal support code inside AMD's Display Core (DC) subsystem that handles power-gating for the DCN 4.2 display engine. It is built as part of the larger amdgpu graphics driver rather than being a standalone module, so it cannot be evaluated for keep-or-remove on its own.

codex reasoning notes (technical)

Not a driver directory: AMDGPU DCN4.2 display power-gating support code under display core (`dc/pg`), not a standalone kernel-bound hardware driver.
