Dynamic Voltage Scaling (DVS) in QNX?

Hi, I am trying to implement a power-efficient real-time scheduling algorithm in QNX. Thus, I am wondering whether there are any DVS supports in QNX?

If there are, which kind of CPU is supported, such as AMD processor with “powernow”? And where can I find the APIs? Thank you all very much!

Power-Efficient real-time scheduling, what’s that?

I do not know what DVS is.

Powersaving feature are part of a separate package TDK, that must be purchase separately I beleive.
