AMD Display Mode Library 2.1 (DML 2.1) helper code

Internal AMD GPU display-pipeline code, specifically the 2.1 revision of the Display Mode Library that calculates bandwidth, watermarks, and pipe configurations for modern Radeon and Ryzen integrated graphics. It is a math/policy helper used by the amdgpu DRM driver, not hardware support code in its own right.

recommendation

This is not actually a driver directory; it is an internal helper library inside AMD's DRM display pipeline. DML 2.1 is the math and timing engine that the amdgpu display code calls into to validate display configurations and program watermarks, so it lives or dies with the surrounding amdgpu driver rather than being evaluated on its own.

codex reasoning notes (technical)

Not a driver directory: internal AMD DRM Display Mode Library (DML 2.1) helper code under the display pipeline, not a standalone kernel-bound hardware driver.
