AMD Display Core DCN 2.0 DIO Helpers

Internal plumbing within AMD's Display Core stack that handles the Display Input/Output block on DCN 2.0 display hardware, the generation introduced with Navi GPUs (Radeon RX 5000 series, around 2019). It is a sub-component of the larger amdgpu graphics driver, not a separate driver in its own right.

recommendation

This is not actually a driver directory; it is a set of internal helper files inside AMD's Display Core (DC) component of the amdgpu graphics driver, specifically handling Display Input/Output (DIO) for the DCN 2.0 generation of display hardware (Navi-era GPUs). It builds as part of amdgpu rather than as a standalone module and has no independent lifecycle.

codex reasoning notes (technical)

Not a driver directory: internal AMD display-core DCN2.0 DIO helper code inside the amdgpu display stack, not a standalone kernel-bound hardware driver.
