AMD DCN 4.2 Output Timing Controller (OPTC) display core component

Internal source code for the Output Timing Controller block of AMD's DCN 4.2 display hardware generation, which lives inside the amdgpu Display Core stack and handles things like generating pixel timings and synchronisation signals for monitors driven by recent AMD GPUs.

recommendation

This is not actually a standalone driver; it is a subcomponent of AMD's amdgpu display code (the DCN 4.2 OPTC block) that is compiled into the larger AMD GPU driver. It cannot be evaluated for keep-or-remove on its own because it has no independent lifecycle apart from amdgpu itself.

codex reasoning notes (technical)

Not a driver directory: contains AMD display core DCN4.2 OPTC subcomponent code inside the amdgpu display stack, not a standalone kernel-bound hardware driver.
