Hey guys, I'm using kernel Zerogravity and there are several options governor, some being easier to understand as: powersave, ondemand and lgfree, but others are not so clear.
Could someone help me understand better how to work each of these governors?
Another question is about the options for I / O scheduler that can not fully understand the function of each option.
If complidado much explain everything, could you pass me some stuff where I can search on the subject?
Sorry my English, I use google translator.

Great, I didn't know all these things!
Up this thread just to ask if someone as tried any governor on V30b and how it work...
Inviato dal mio LG-P970 con Stock V30B
If you're on stock kernel, dont use the default ondemand governor cuz it wont get into deep sleep.
Instead change it to Interactive.
And about zero gravity kernel, I didnt really try it, but many people said many governors had weird scaling between freqs, so just a few governors acted normally. Someone made a small review about how governors are working on the kernels thread. =)

Updated kernels that now include this fix:
.35 = francos v1.1-02102011 and newer
.32 = fserves gbs v18b2 and newer
It seems that some phones experience camera flicker when overclocking and some don't.
Example of Camera Flicker
I noticed that I didn't experience camera flicker with Paulos .35 kernel so I dug through his sources and found the routine that solved my problem.
Note - I'm not a developer and I've only tested this with francos .35 sources.
Extract acpuclock.c to arch/arm/mach-msm and compile
I've contacted franco and fserve via PM with my findings and I know that franco is including it in his next release. However, if you can't wait.... do it yourself!!
THIS IS NOT A FLASHABLE ZIP.
is it .35 only, right?

I don't think so. I know that I get camera flicker with both francos and your .32 kernels but not with Zacks. He has also implemented this or some variation (wish I could see his sources).
If you'll compile golldenleaf or gbs with this fix I'll test it for you.

I hate people that don't share their sources... It's completely against GPL. But well like I told you before thanks for that finding. I'll update my .32 and .35 when I have time.
CAF FTW! =), nice finding btw!
CAF patches/code can do wonders sometimes ;D
well that sounds good waiting for franco next release along with the integration

Guess where he got the CAF patches from...
1. No, smartass it's obsolete, you have smartass2
2. No, recompile the kernel yourself if you want vsync off
3. No, there's plenty of documentation and explanations about that

He does now in his newest versions but he applied this fix in version 3.3 or something (sites down now can't confirm the version number). This is when he stated in his changelog that he applied Paulos camera fix.
He also neglected to mention that he was using francos sources as his base (so wrong). Comparing franco and Zacks changelog and looking at the date/time stamps it's hard to argue this.
Edit - Sorry franco I didn't see you post before I began mine.

I recommend you start from fresh again. Install the rom, then wipe cache and data before reboot. And don't set minimum frequency to 700MHz, as that will keep the phone running at that frequency while it's at sleep, effectively causing battery drain. Also if you restore apps after installing CM9, only restore the apps itself and *not* apps settings. That can cause all sorts of problems.
Does anyone know why the email app generates a force close?

installed as it should be. flashed to alfs rom, installed ginger dx v028, then installed alfs update patch and it seems to work fine.. Fresh install and after entering settings happens strange things, sometimes loading facebook app is just the same. Screen attached. Anyone know how to fix this? Never happened with earlier gingers on stock rom.
The thing is.. you have to touch a bit left of buttons, as the touch matrix is in correct position, but the graphics a float to the right. If i did not reboot, it floats more and more.
any help appreciated

Please atleast check what all features you're phone provides you..
And read the bug log in the rom's thread b4 using any rom or kernel..
Now for you're problem go to performance settings as you did b4 change governor as b4
(recommended 600mhz smartassv2 overclocking will drain battery and is not good for cpu) (overclocking cpu means when you push you're cpu beyond its default limits, ours have 600mhz)
and at the bottom last option would be to "set on boot" just click on the box beside, it will be checked..
Now you shouldn't have any question, i guess..
to the point, please someone take a look at my attachment. this's Xperia V.
*last changed i had before :
-updated to .140, and flash vKernel, removed bloatwares, installed init.d via PimpMyRom, use intellidemand gov.

thats screenshot i taken from catlog. it something like cant access/open files from interactive gov's folder at /sys/device/system/cpu/cpufreq/
when i take a look at that error (/sys/device/system/cpu/cpufreq), it doesnt have folder named interactive.
i think this path is telling 'what' governor are im using now.
now, i think i resolved my own problem
the problem is that when i change governor besides interactive (default V's governor), that error will appears continuously at catlog.

Of course i have root.
im using doom's kernel and installed superSU after flashing .140 ftf.
if i dont, i cant change the governor.
take a look again properly this SS (see this post attchmnt), its weird.
i dont have this problem before when i changed governor.
it happen when i change other governors EXCEPT interactive.
for now, that continuously error dissapeared bcoz use interactive gov.
Yes that was my point, the governor is not actually changing, hence the reference to interactive whilst using another governor.
Do you have any init scripts running?

that script is script created from SystemTunerPro app. so when i change gov from that app, the script will rewrite it automaticaly.
i already removed that script and use SetCPU, it still have same problem.
i can only thinking it happen from kernel related.
maybe the only way i can do is re-install ROM and kernel, but later.

ONdemand use to put the cpu on full throttel and have a considerable battery drain i think interactive doesn't does this?ONdemand rarely uses the middle step frquency? my earlier phone have the tegra 2 processor and it used the interactive governor it has awesome standby mode it rarely looses 1% battery overnight anybody have any solution for our s3 mini because it have considerable amount of battery drain while in standby mode nearly 10% overnight

has anyone else tried out this new Samsung kernel?
performance down...
IT seems that they cheated us again the new governor doesn't seems to work like most of the interactive works i think they might be renamed the ondemand or it has been bymistakley happened because to work interactive efficiently more middle step frequencies are required like 650 hz 920hz etc more the frequency switching option better the interactive will work but in our case we have 400 AND 800 only and moreover i fell some lag in the ui and some games while using this kernel
