AMD GPU Legacy DPM Power Management Code

Internal power management code shared by AMD's amdgpu and radeon graphics drivers, implementing the older Dynamic Power Management (DPM) logic used on pre-Vega AMD GPUs before the newer SMU-based power stack took over.

recommendation

This is not actually a driver directory; it is a support library that lives inside AMD's GPU driver tree and provides legacy dynamic power management routines for older Radeon and early amdgpu hardware. It is not loaded as its own module and only makes sense in the context of the broader AMD graphics stack.

codex reasoning notes (technical)

Not a driver directory: AMD DRM legacy power-management support code under pm/, not a standalone kernel-bound hardware driver.
