Ondemand - hotplug - mot_hotplug

[bhp117]

What does each of these settings different from each other?

Ondemand
Hotplug
Mot_hotplug

I've googled it and there wasn't much info on these settings

I just wondering which can save more battery and still keep responsiveness

I just know how ondemand works but not sure how hotplug and mot_hotplug different from ondemand

Thanx
