Hi guys.
I would like to know the differences amongst various governors. I googled a bit and both on the net and XDA I found some explanations, but not all the governors I have are properly explained. Some of them are not explained at all.
Is there anybody able to help me?
I found some info here and here
The governors I have with FM1.5 not explained are:
  • lazy
  • lulzactive
  • lagfree
  • intellidemand
  • smartassv2
  • ondemandx

Ok, some of them like lagfree could be self-explanatory, but I would be grateful if somebody could be more clear...

Thanks as usual to all!!

I was in Prague for a week

Ok, so, to be honest using only Google I found this:
lazy (http://forum.xda-developers.com/show....php?t=1276092) - is ondemand but with an added option to stay longer on a certain frequency. This is due to the fact that some CPU's dont like too quick freq changes when sampling rate for decision making is set too low. See link for more.

lulzactive (http://tegrak2x.blogspot.com/2011/11...vernor-v2.html) - is basically interactive governor with added smartass bits and variable (as opposed to fixed amout) frequency scaling, based on currently occuring cpu loads. Has, like smartass, a sleep profile built-in. See link for details on exact scaling.

lagfree (http://forum.xda-developers.com/show....php?t=1272933) - seems to be ondemand but with a lessend tendency to ramp up to 100% but rather also use steps available in between 0-100%.

intellidemand (freely translated from http://www.android-hilfe.de/root-hac...-governor.html) - behaves like ondemand when the system is under heavy use, it behaves differently when the system is mostly ideling. That mode is colled "browsing mode" or "browser mode" or whatever. It seems to be some sort of "intelligent" demand sensing/analysing ondemand governor.

smartassV2 - this one should be known. It's the same as smartass(V1) but tweaked. Same code author. I heard one should use smartassV2 instead of smartass when available.

ondemandx - is ondemand with an added sleep profile built-in. I believe all ...X kernels are the default kernels but with an added sleep profile.

Just in case you wonder: I use Savagedzen, I somehow like it best. And I have to get up at 4:20am thats in 2:48h so you may excuse me if I go to bed.
