The DMCUB is the Display MicroController Unit B, a display microcontroller that is required for Renoir to support realtime display features (ABM, PSR) and display hardware initialization. This patch series adds the required firmware loading support in amdgpu and the DMUB service support for amdgpu_dm and dc to interface with the DMCUB. The term DMCUB will generally refer to the actual microcontroller while DMUB will generally refer to the software interface.
