AMD DCN 3.1 Display Mode Library (DML) support code

Internal mathematical and bandwidth-modeling code used by AMD's amdgpu display stack to validate display configurations on DCN 3.1 hardware (the display engine in Ryzen 6000-series "Rembrandt" APUs and related parts from around 2022). It calculates timings, memory bandwidth, and pipe arrangements that the actual display driver then programs into the hardware.

recommendation

This is not actually a driver directory; it is a helper library inside the AMD display core (DC) that does the math behind picking valid display configurations for DCN 3.1 GPUs. It ships as part of amdgpu and has no separate lifecycle of its own, so the keep/remove question does not apply to it independently.

codex reasoning notes (technical)

Not a driver directory: internal AMD Display Mode Library (DML) support code for DCN3.1 within the amdgpu display stack, not a standalone kernel-bound hardware driver.
