AMD Display Mode Library bandwidth and timing calculations

Internal calculation helpers used by AMD's Display Core to work out memory bandwidth, pixel clocks, and watermark values needed to drive monitors attached to Radeon and Ryzen integrated GPUs. It is shared math code consumed by the AMDGPU display driver rather than something that talks to hardware on its own.

recommendation

This is not actually a driver directory; it is a collection of mathematical helper code inside AMD's Display Core (DC) stack that computes bandwidth, watermarks, and timing parameters used by the real AMDGPU display driver. It has no hardware binding of its own and exists only to support the broader AMD GPU display pipeline.

codex reasoning notes (technical)

Not a driver directory: contains AMD Display Mode Library calculation/helper code under the DC display stack, not a kernel-bound hardware driver entry-point directory.
