AMDGPU SMU13 power management helpers

Internal support code inside the AMD GPU graphics stack that talks to version 13 of AMD's System Management Unit, the on-chip microcontroller that handles power, clocks, voltages, and thermals on recent Radeon and Instinct GPUs (RDNA 3 / CDNA 3 era, roughly 2022 onward).

recommendation

This is not actually a standalone driver; it is a sub-component of the larger AMDGPU DRM driver that implements the SMU13 power-management protocol. It only makes sense as part of AMDGPU and is not a candidate for independent lifecycle decisions.

codex reasoning notes (technical)

Not a driver directory: this is the SMU13 power-management support subdirectory inside the AMDGPU DRM stack, an internal helper/component rather than a standalone kernel-bound hardware driver.
