On Genode, the current drivers for the Pandaboard comprise USB (for HID
and networking), HDMI, and SD-card. There is currently no driver for the
dynamic voltage and frequency scaling (DVFS) feature of the OMAP4 SoC.
So I would just expect a higher power consumption of Genode compared to
native Linux, which comes with a DVFS driver.

That said, I see no real show stopper that would speak against
implementing such a driver. The DVFS driver would run as normal Genode
process like any of the other drivers.

Are you interested in having a closer look on this topic? If yes, I
would be happy to discuss possible approaches about how to integrate
power saving features with the Genode architecture.

Cheers
Norman
