AMD DCN 3.0 Display Input/Output helpers

Internal source files for the Display Core (DC) component of AMD's amdgpu graphics stack, specifically the DIO (display input/output) building blocks for the DCN 3.0 display engine found in Navi 21/RDNA 2 era Radeon GPUs. They provide link encoder and stream encoder programming used by the larger amdgpu driver.

recommendation

This is not actually a standalone driver; it is an internal subdirectory of AMD's amdgpu display-core code that implements DCN 3.0 specific helpers. It only makes sense as part of the larger amdgpu DRM driver and cannot be evaluated for keep/remove on its own.

codex reasoning notes (technical)

Not a driver directory: internal AMD DCN3.0 display-core DIO implementation subdirectory inside amdgpu/drm, not a standalone kernel-bound hardware driver.
