AMD DMUB Display Microcontroller Support Code

Internal source files supporting the DMUB (Display Microcontroller Unit) firmware interface used by AMD's amdgpu display stack on modern Radeon and Ryzen APU graphics. It is a helper subtree inside the larger AMD display driver, not a standalone driver of its own.

recommendation

This is not actually a driver directory; it is a nested source subtree within AMD's amdgpu display code that provides the host-side glue for talking to the on-GPU DMUB microcontroller. It lives and dies with the broader AMD display driver and is not separately loadable or removable.

codex reasoning notes (technical)

Not a driver directory: nested `src` subtree for AMD DMUB display microcontroller support code within the amdgpu display stack, not a standalone kernel-bound hardware driver.
