Bug Description

spawned from bug 1513450
as well as some investigation by tvoss
devices need to be tuned to utililze the interactive governor; available method employed by android/apple is to switch to interactive when the device is picked up (sensor) or screen is unblanked

this actually applies to all devices, but i could only find/link our reference device projects.

What needs to be changed on the kernel side for this?

I don't think we need specific kernel patches. One thing I noticed:
The interactive governor (which is *the* hook on Android) is missing
on Krilling
The MX4 supports the interactive governor, though.
