AMD DCN 3.21 Display Mode Library helpers

A subdirectory of AMD's Display Core code containing the Display Mode Library (DML) calculations specific to the DCN 3.21 display hardware generation, which is part of recent Radeon and Ryzen integrated graphics. The DML computes bandwidth, watermark, and pipe configuration parameters that the actual amdgpu driver consumes when programming the display engine.

recommendation

This is not a standalone driver but a support module inside the larger amdgpu display stack. It provides the per-generation math and timing models that the real driver relies on to drive DCN 3.21 displays, so it lives or dies with the surrounding AMD Display Core code rather than being evaluated on its own.

codex reasoning notes (technical)

Not a driver directory: contains AMD DC display-mode-library (DML) generation-specific helper/model code for DCN 3.21, not a kernel-bound hardware driver entry point.
