[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
In a way it does have impact on battery consumption. It adjust three paramaters (of many) used by the processor's scheduler in it's multitasking behaviour.

basically it adjust the minimal time interval each running process should get per multitask-cycle(granularity) and the total time-interval in which it will try to give all running processes a turn (latency).

The ratio between these two depends on how many processes are running on your device and needing service.

The preset settings in extweaks are just 3 different ratios (balances) for these values, samsung default having the highest ratio, thunderbolt the lowest.

So it depends on your setup, which one suits you the best, and gives the best result in repsonsiveness and battery consumption.

If it tends to become more unstable with undervolting and a certain CFS setting, this means the processor is being loaded more because of this CFS setting and you should try another balance/setting with a different (higher) ratio (which is in the presets , the samsung one)

If you mean the wifi issue battery drain, no that's not in any way configurable as far as I know. I only have my suspiscions it's in some way related to the su binary (at least in my case, but like I said, time wil have to tell... )

Is it true that pegasusq in 3.3.3d doesn't scale to the freq between min. freq and 500 MHz anymore? If I use 100 MHz as min freq, the 200, 300 and 400 MHz will not be used.
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
From where did you get that idea?

The governor will scale according to the load so if it only requires 300 MHz then it will only use that much. It will use all values between 100 & 500.
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
TBH I recognized something similar after flashing 3.3.3. Before and now I have used pegasusq/sio on default settings.
[Galaxy S II Q&A, Help & Troubleshooting] fusionjack:
It is not my idea but based on fact...
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
the default pegasus settings have been tweaked a little by GM, giving this effect

if you play around a little bit with the pegasus settings, you'll get more usage on the lower freq's ; it's a matter of personal preferences....
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Johnbeete, you are right as usual.

You can tweak a little bit pegasusq governor (using eg. SetCPU app) by your own. Just set freq_for_responsiveness < 500 MHz or even disable it by setting the same value as scaling_min_frequency and see a difference.

i think, that fluxi kernel doesn't support custom init.d scripts. Only the ones mentioned under rom control in aokp are working using liberty.cfg !?

Is there any way to increase the general speaker volume with this kernel? I used fluxi's before which gave me the option to set a value called "DAC ATT". It even made call-in volume louder which is way to quiet on my phone.
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
I just quickly went through fluxi's github repository (kernel sources), and had a quick look at his initramfs

https://github.com/myfluxi/xxICSInitramfs

(where support for init.d is usually allocated), and I couldnt find anything refering to the init.d directory, like in siyah, so I guess his kernel doesn't support the use init.d user customizations, unless fluxi uses a different approach. To be one hundred percent sure you'll have to ask that in his thread (I never used his kernel, so i'm not 100% sure).

So as to your question, how you can enable init.d support?

I'm afraid you'll have copy his sources and do some patching on your own, and rebuild the kernel, to have that.

One thing that differs from 3.3.2 to 3.3.3d at least is that on AOKP roms, is that on 3.3.2 the 'random' but 90% reproducible camera flash is to a 100% fixed on lgCamera 6.4 beta 9, http://rubberbigpepper.com/en/node/201 the only decent cam without a 'random' flash, is at 3.3.3d 100% reproducible, by the first thing you do is chose the videomode from the camera mode.

I've been a really (almost possessed) Siyah fan, and using all the new ones at once they were released.. but the only thing better in 3.3.3d is the ability to remove the annoying 4 fast home presses to invert it.

I never knew a kernel could change a generally flawed galaxy S2 AOKP camera code to the worse?

as I said, before installing the 3.3.3d It was impossible to reproduce the flash bug.. but after it, it's even possible on 3.3.2 sometimes.

I am the XDA's major flash whiner, and reproducer, and can easily with 5 simple steps make anyone using AOKP that claim they have a flash free camera change their mind, and admit it's 'random' .. which it isn't since I just told the way to cause it.

PLZ have a look at this.. I know that even though I've been a loyal follower for a loong time, I only donated 15$.. but I still want Siyah to tower above all others! Since you were so ahead of your time.. and still is when it comes to stable dual booting!

To all who still have slight lags with pegasusq in hardware hungry games:

Set "down differential" to 30.

Some of the tables in Pinball Arcade (e.g. Fun House) weren't 100% smooth.

This has solved it.

Unfortunately i don't know if there's a free app available that can change the governor settings for pegasusq.

I use SetCPU.

Hi. I want to try MIUI ROM, so I want to flash on second ROM but, I don't do a 2nd ROM never before and I want to be sure...

Only need to flash on second ROM via CWM? So, how to select what ROM you want to boot? I see an option to swap 1st and 2nd ROM is that the way?

Also, is there any problem to Flash MIUI on 2nd ROM? Can affect in any way to 1st ROM?

Another question. Activating 2nd ROM will use 2Gb of SD/USB memory, so if later I want to delete 2nd ROM and gain again this 2Gb, how will do?

does anyone try this? what 0 means and 255 means?

what is the difference between “user_cb” and “user_cr” ?

[Galaxy S II Q&A, Help & Troubleshooting] confusedmuse:
Yes.

But: (from Siyah changelog v3.2.3)

-you will have an error when trying to flash to 2ndROM before running ‘Wipe 2ndROM data/cache’ at least once. you need to create 2ndROM data and cache files in your sdcard first.

No. After the Samsung logo you'll have 3 seconds time to press home or vol down to boot into the secondary rom.

If you touch the screen or the time runs out the primary rom will be booted.

The 2ndary doesn't affect the primary rom. But it has to be ICS based.

You can't flash a GB rom as secondary.

Delete the folder ".secondrom".

Mate try to use the whole 18 steps range as it should give u better battery life and better smoothness. I use 18 steps (200-1000) and got 5 hours screen on time. Also try Pegasusq / SIO combo.
[Galaxy S II Q&A, Help & Troubleshooting] spotlight79:
Thanks for the suggestion, but... you had 5 hours screen on with 11 hours stand by. I had 4 hours screen on with 33 hours stand by. I could easily get 5 hours with 11 hours stand by. ;)

I found the 18 steps to be pretty useless as the most used are anyway these 5. And I have the feeling that the battery drain is actually a bit higher with the 18 steps (it's a subjective feeling).

I'm currently using Launcher 7 and it's pretty hard to achieve smoothness with that launcher (that's why I'm not underclocking). When you achieve that this launcher runs smoothly, then everything on the phone is buttery smooth. With my settings I have that, with 18 steps there was some lag.

As for the scheduler, yes, on my next cycle I planned to use SIO.

As a recognized developer, you should know better, no discussion should take place in the development thread anymore, bugs can be reported here, GK would see them, but if you don't have any logs, then you should not be posting in the Development thread, and it has to be excessively policed until everyone knows, look at the CM9 development thread and the way it is policed, and it will always be excessively policed (including huge red font) and moderators handing out bans and you are already the primary cause of the Kernel thread becoming Better Battery Stats part 2.

[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
I would have almost slightly agree with you....weren't it for the fact that I think a lot of the random problems were due to an underlying problem (not kernel related)

namely the interaction with superuser binary. After replacing this with superSU:

Day 4 of testing: not a single incident/misbehaving

Batterylife seems a slight bit better compared to 3.2.7.1 : averaging 1.2%/hr with little use (only syncing every 15 min.). Stable and solid (like we are used to from GM). Going 34 hrs., still 60% battery left.

I wouldn't be surprised that other kernel's in some degree are also experiencing weird behaving's due to the superuser su binary.

[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
when using pegasus as governor, it disables the second core (or not)

I explained in a prior post, that this is not a very useful setting, because the beauty of pegasus is that it's hotplug aware and uses the secondcore efficiently (with the right settings).

Disabling the secondcore with pegasus, you'll just degrade pegasus to just a version of the classical governor (depending on your settings, something in between ondemand and conservative). It's a more useful setting on a the S3, where you can configure pegasus to use 2 or 3 cores instead of all 4.

[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
Personally I prefer it that way, but practically, just installing superSU should be enough. After installing, open superSU, and it will prompt you to install it's own su binary ; allow that, and your set to go, After that all apps needing root will be handled by superSU (despite the fact that superuser app is still present...)

Just open the root management app of your choice and update binary

Samsung Galaxy S II Tapatalk2
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
That would be something like this:

* uninstall superSU (it will unistall it's su binary aswell)

* open the still present superuser app

* goto preferences

* scroll down to general section

* tap on 'check for su binary update' and say yes to update

* this will install the original superuser su binary

* done

If anything goes wrong, you can always hit 'auto-install root' in extweaks and reboot. This should do the job aswell...

EDIT: this was the long version ; you can follow BrandoHD's short version (post above.. ) aswell :) :)

EDIT2: funny thing: I thought I'd give it try and do the walkthrough myself, just to be sure, so I must have been about 5-10 min. on superuser, and guess what....

I started getting weird behaviour almost instantly....so I'm going back to superSU, and staying there :) (so I don't think once you've felt the difference, you'd want to go back...)

EDIT3: another thing I've noticed just now...even the battery charge animation (CM9 version) with phone turned off is working now (it didn't before....)

SuperSU strange observation on apps tab

Hmmm. Although SuperSU is working perfectly after many hours of use (things really do seem smoother) I have noticed a strange thing. When opening the SuperSU app and swiping to the "apps" tab there is nothing listed at all - it's a blank list. Shouldn't this be populated with the apps that have been given superuser access. However, in the logs tab, the apps are shown but not on the apps tab. What is the apps tab for then?

Its not a problem as such, just a peculiar observation.

Anyone else noticed this?
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
It is a problem. Don't know why it would be happening though. Apps that have been given su permissions should be there. This maybe a short in the dark but try clearing the app cache & doing a reboot or maybe install the app again.
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
did you look under the superuser app if they are still registered under superuser?

if yes, you can unregister them there (you will find superSU registered there too ; leave that on there, just to be sure), and they will popup under superSU when you use the app (requesting root) for the first time after that...

[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
Alright now I'm stumped. So based on what your saying it is possible that high usage can be attributed to a root management app? How is that possible? If you could explain, as I have also changed over to SuperSU & I find no changes in deep sleep power drain. I usually get between 0.3% & 0.5% drain an hour.
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
You're probably one of the happy few that were not having any negative effect from the superuser binary, because as I see your battery usage is very good. It all depends on each inidividual setup, apps, data/wifi always on/off, location service enabled or not, syncing configurations, etc.

Apparantly the current versions of this su binary from superuser has some imperfection, that is causing some clogging up of the system in a way that it's functioning less efficient than it could be. How exactly it is misbehaving, I don't know. I just summed up all the strange effects I have noticed during the past week, and couldn't pinpoint any single part of the system or app that could be causing this, until I decided to try superSU (which I was always using prior to ver 3.2.5.2, when it got uninstalled by that particular version). After that everything fell into it's right place and the system respons was totally what I was used to in the past. So the only conclusion I can make is that superSU's su binary does the job better than superuser's.
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
You're right in saying that setups play an important determining factor & it could well be in all probability that superuser's su binary is messed up but I wouldn't go with happy few. More like frustrated few because of the networkstats wakelock:mad:. It's thrown my entire deep sleep into a bloody mess. I used to always use SuperSU till version 3.2.5.2. Did have a bit of lag when on superuser but now it's gone & everything is smooth again. If it weren't for you tip to try out SuperSU I would still be having to annoying lags which would appear randomly so thanks for that.
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Speaking of which. I've been messing around with modems trying to solve this problem, because it's the only thing I hadn't tried. I've been using Vodafone AU's DULP4 modem (with an I9100T) since early yesterday, and the NetworkStats wakelock seems to be gone. Now getting 98/99% deep sleep in idle compared to 80's% (plus drain) when the wakelock is present. I'm not going to start jumping for joy just yet because it has disappeared for a day or two in the past & then reappeared, but this looks promising.

Maybe try some different modems out (particularly later ones released with stock firmware for your carrier ?) & see if that helps ?
