Internal power-management code shared by AMD's open-source Radeon graphics driver, implementing clock, voltage, and thermal control for pre-Navi GPUs such as the Polaris, Vega, and earlier GCN families. It is a subcomponent of the amdgpu driver rather than something that binds to hardware on its own.
This is not actually a driver directory; it is an internal helper library inside the AMDGPU graphics stack that handles power management logic (clock and voltage scaling, thermal limits) for older Radeon GPU generations. It has no standalone module entry point and exists only as support code consumed by the main amdgpu driver.

codex reasoning notes (technical)
Not a driver directory: AMDGPU PowerPlay hwmgr is an internal DRM power-management helper/library subtree, not a standalone kernel-bound hardware driver entrypoint.
