Hi !

>From what I've seen, the OnDemand governor works using a timer/workqueue
pair.

That annoys me a bit as the setup I have on PowerMacs can take several
ms to transition (due to voltage transition mostly). I don't like the
idea of hogging keventd that long.

Wouldn't it make sense, especially for setups where transition latency
is high (by high, I mean significant compared to HZ for example), to
actually spawn a kthread and do the sampling & switching from there ?

Regard,
Ben.
