Internal support code inside the open-source Nouveau driver for NVIDIA GPUs that handles the on-GPU Performance Management Unit, a small microcontroller embedded in NVIDIA cards used for tasks like power and clock management. It is one piece of the larger Nouveau DRM driver rather than a separately loadable driver of its own.
This is not actually a driver directory; it is an internal subcomponent of the Nouveau GPU driver under drivers/gpu/drm/nouveau. Lifecycle decisions for it follow Nouveau as a whole, so it should not be evaluated for keep-or-remove on its own.

codex reasoning notes (technical)
Not a driver directory: this is an internal nouveau NVKM PMU subdevice implementation under the DRM driver, not a standalone kernel-bound hardware driver directory.
