--- Comment #11 from Alex Deucher <alexdeucher at gmail.com> ---
The GPU dynamically adjusts the clocks and voltages at runtime based on the
load on the particular engines or hw subsytems.  You can use the
pp_power_profile_mode interface to adjust the heuristics that determine how the
GPU transitions through power states.
