--- Comment #14 from Alex Deucher ---
The information in radeon_pm_info represents the current GPU power state. It
will vary dynamically with GPU load. E.g., if you are rendering stuff on your
desktop, the GPU clocks and voltages will ramp up/down on demand. In the
console without X running, there is no GPU engine load so the clocks stay low.
Note that display requirements can also influence the GPU power state. E.g.,
if you have a large display that requires higher display clocks, the GPU may
have to boost the power state to accomodate the higher voltage requirements of
the display.
