Root How do overclock kernals actually reach their max speed?

[andrew53517]

So I was wondering how they actually reach their max speed? If you have a kernal that has 250, 600, 800, 1000, 1200. Does it start at 250 then go 600, 800, 1000, then finally hit 1200? Or does it jump to the necessary speed that your using (like start at 250 then it could go to 1000 then 1200)? Because if it has to go through each speed to get to its max, then a kernal with 5 different ones would be much better than 10 wouldn't it? I've never seen this question asked before, so does anyone know how they actually get up to their max?

Just so everyone knows I'm rooted and running overclock of 1200.. I have it set up. Just want to know how it works.

You choose the speed you want via setcpu (autodetect)

No i know that, I have mine set to 250 and 1200. I was wonder how they it gets there when I'm using my phone. Like does it have to go to 600 then 800 then 1000 then finally hit 1200? Or will it skip speeds and go to like 1000 then 1200?

What I'm asking is when it trying to get to it's max speed, how does it go about doing that? in what increments?

From what I've observed, the processor ramps up to a speed proportionate to system demand.

There is a widget available on the market called overclock widget which displays the current clock speed (though it only updates in 5 second intervals minimum). I use it occasionally just for fun, and I've seen intermediate speeds reported between my max and min. It's not exactly an accurate real time assessment, as a lot can happen in those 5 second intervals, but I've definitely seen intermediate speeds.

However, this doesn't necessarily mean that the processor throttles up in a stepwise fashion. In fact, I would think that the processor would throttle directly to the max setting if needed.

See this is what I would think.. But I'm not sure.. I have a feeling it would. Thanks for you're opinion, anyone else care to share what they think?
