AMD DCN 3.2 Display Mode Library

A helper subdirectory inside AMD's Display Core code that holds the Display Mode Library calculations for the DCN 3.2 generation of display hardware, found in Radeon RX 7000-series GPUs and related APUs. It computes bandwidth, watermark, and pipe configuration math used by the GPU driver when programming the display engine.

recommendation

This is not actually a driver directory; it is an internal math and configuration helper library that lives underneath the amdgpu DRM driver. It has no device binding of its own and only exists to support the surrounding AMD display code, so it cannot meaningfully be evaluated for keep-or-remove on its own.

codex reasoning notes (technical)

Not a driver directory: this is an internal AMD DCN3.2 display-mode-library subdirectory under DRM, not a standalone kernel-bound hardware driver with its own device binding/entrypoint.
