AMD DCN 3.0 Display Mode Library helpers

Mathematical and configuration helper code that the AMD GPU display stack uses to validate and program the DCN 3.0 display engine, found in Radeon RX 6000 series (Navi 2x) GPUs released starting in 2020. It calculates memory bandwidth, watermarks, and pipe layouts rather than talking to hardware directly.

recommendation

This is not actually a driver directory; it is a set of internal helper and modeling routines (the Display Mode Library) used by the AMD amdgpu display stack to calculate bandwidth, watermarks, and pipe configurations for DCN 3.0 generation display hardware. It ships as part of the broader amdgpu driver rather than as a standalone module.

codex reasoning notes (technical)

Not a driver directory: contains AMD DCN3.0 Display Mode Library helper/model code used internally by the amdgpu display stack, not a standalone kernel-bound hardware driver.
