[Q] CPU Governors

---

Hi everyone,

Like most people I've been trying to find that optimum balance between performance and battery life in my Aria. I'm running CM7.0.3 and the latest version of drowningchild's kernel. With that kernel I switched setCPU from ondemand to smartass, and I can already see the CPU spending most of it's time in either 400 or 480 MHz, but when playing a graphic intensive game it'll go up to 806 MHz and run great.

But, here's the problem. With things like less graphic intensive games, or playing videos, smartass doesn't want to scale up to a useful clock speed, and things get choppy. I switch back to ondemand and everything smoothes out again. I don't want to keep it in ondemand all the time though, because then it's spending half the time in 806 MHz and eating up battery unnecessarily.

So, is there a better governor option for me? Or maybe a way to "whitelist" apps within setCPU, to designate apps that always get the max clock speed?

tl;dr: smartass isn't that smart in certain situations. Is there a better way?

Check out the app "Tasker" in the market. It will allow you to reconfig the governors automatically based on a slew of complex conditions.

If you want smartass roll back to 7-5 of my kernel and it should be fixed as I tweaked it to jump around less in newer versions

I'm still messing around with the new kernel released & will add smartass very soon & hopefully optimized

Hey yea you're right, I didn't notice you had a new kernel out. I'm running 7-5 still but I'll upgrade once smartass is working in the new version.

I've been using "conservative" setting. Although when it initial opens a resource intensive app, its stutters a little, and then compensates by clocking up. I haven't had an issue where a game didnt want to run smooth (also at 806mhz).

I run on demand at 320/768. This to me seems to be a very good combo. The 320 min makes a noticeable difference in responsiveness without much sacrifice to battery. I've found the Max cpu setting doesn't make too much of a difference in most situations.
