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)

The driver uses 10khz units internally. Without dpm the output adds the extra 0.

30000 = 300 Mhz
