Runtime power management

Parent article: Runtime power management

Let's say that there's around 1 billion computers, and 1% of those are running linux - so 10 million linux computers.

At a saving of 0.2 Watts per machine, that's a total saving of 2 mega watts. This is about the power output of quite a small power station.

If the started power management work would stop at USB, it would be rather
pointless.

And for battery powered devices even that's a huge amount. If you want
the device to be able to idle for weeks, all this kind of extra power
usage needs to be fixed.

Just curious: Does the 1 billion computers estimate includes embedded one?
If not, how including embbeded devices will change the estimation?

Thanks
