Comment # 21 on bug 66963 from Sergey

Here is '/sys/kernel/debug/dri/0/radeon_pm_info' output I get:

1. with dpm=1
    uvd    vclk: 0 dclk: 0
    power level 1    sclk: 30000 mclk: 40500 vddc: 900

2. without dpm=1
    default engine clock: 500000 kHz
    current engine clock: 499500 kHz
    default memory clock: 500000 kHz
    current memory clock: 495000 kHz
    voltage: 1000 mV
    PCIE lanes: 16

The output format differs, but if clocks values dimensions are the same, then
it is about 10 times less the in (2)
