Internal support code inside the amdgpu graphics driver that handles the System Management Unit version 11 power-management firmware interface used by AMD Navi (RX 5000 series) and Sienna Cichlid (RX 6000 series) generation GPUs. It manages clock, voltage, and thermal control on those cards rather than being a separate driver in its own right.
This is not actually a standalone driver directory; it is a subcomponent of the amdgpu DRM driver that implements the SMU11 power-management protocol for recent Radeon GPUs. It lives or dies with amdgpu itself and is not subject to independent removal review.

codex reasoning notes (technical)
Not a driver directory: contains amdgpu SMU11 power-management support code under the AMD DRM subsystem, i.e. an internal helper/component directory rather than a standalone kernel-bound hardware driver.
