[Q] Undervolting the GPU of the I9100 - Galaxy S II Q&A, Help & Troubleshooting

Hallo community,
i was reading here in forums about overclocking the S2 to find the solution matching my needs. I want to UNDER-clock my phone to get a better batterylife.
I allready made many optimizations so I have really good Bat-Time.
Now I'm at the point where it comes to Undervolting. Unfortunately the solutions shown here in forums dont work for my setup.
I have a i9100 + Supernexus2.0 build4 ROM (AOSP 4.2.2) + DorimanX 8.13 Kernel
CPU-Undervolting is no problem......the problem starts when it comes to modify GPU-settings. None of the Software discussed here regognizes my GPU. Antutu for example says "GPU not supported" on GPU-tab. (tryed "voltage control", "antutu", "setCPU" "Tegrak" NS-tools" and many others )
Now I'm on the point where I accept, that there is no simple-software-solution to automize my settings (or perhaps I didn't see it) and I try it with "STweaks"
So what I going to try now is to modify the the different steps and set a voltage/mhz manual everytime I boot-up.
But in other Forum-posts I read, that there are 3-GPU-steps. In STweaks there are shown 5 steps to me ?!
I dont have the right clue what Step is set in which state. What does these steps mean exactly ?
Can anyone help me how to Undervolt my GPU correctly ? I dont need 267MHz+1050mV. I'm happy with 160MHz and 900mV (for example) The games I play are not very hungry. Also I heared from other users that undervolting there GPU gave them +3 Hours playing time, unfortunatly I can't reproduce that here
Is it perhaps because I have 4.2.2 ROM with newest DorimanX, that I cant do the solutions that work for others ?
THX 4 any help
best regards
revnu

[Tests] Improving Speed technics Gen8 devices

I posted in Chulri's thread but here will be better seen from anyone.
Device : A70IT , fw 2.1.08
Is anyone willing to try something I DID and seems to me to give my tablet significant speed increase. I want to check if it is real or just my imagination.
In my latest fw 2.1.08 installed, I flashed 2.1.08 initframs and 2.0.71 zimage (both from chulri files, first post . you know how to : flash kernel from developer menu at boot holding vol- button)
And I set the speed with SetCPU 2.1.1a to 1000mHz both min and max. Also in settings menu I choosed "Overdrive"
Please test and report.
Thanks

Of course it is real, since your tablet will run at maximum speed all the time instead of running at 1000mhz for heavily load task only like default (not count the overclock here). However, it will consume more battery and get hot faster.
If you don't care much about battery life, then it will do the trick.
Before the 2.0.71 zimage kernel I was running at full speed the 2.1.08 kernel. After the switch I noticed more speed gain. That's why I need confirmation from other users.
I have had my A70 set to 1000 min and 1200 max for months now, and I have seen a speed increase, and only a little extra battery drain.

What kind of test you want to?
Have you try OverClock? Archos Gen8 can OC to 1.2GHz as well

[Q] I/O schedulers disabled/not included in kernel

Dont know if the topic name is right but i am interested why when on my tablet install no frills cpu control or antutu cpu master pro i have no option to select io scheduler when on my phone i am able to do this and playing with this helped my phone to be significally smoother. Is there any workaround or kernel parch or something ? Yeah i know about custom roms, i am running one on phone (jellyblast) but there is coming problem that i am using very uncommon tablet (emgeton consul 3) .

For the best CPU performance set the min. CPU frequency to 600 MHz in Settings/Performance/Proccessor, and activate 'Set on boot'
Can GP 3.6 support 1200 Mhz overclock ? I read the motorola defy can be overclock to 1300 Mhz.
EDIT :
With conservative governor (1100-600 Mhz), I get a better antutu score than ondemand governor : 4807 points.
Will the bluethoot pan sharing connection work?
I used my omnia i900 with some other devices (like galaxy s3) and it's work but with gingerbread or ICS devices didn't work

If we've the 4.2 Player, will we have to compile the kernel ourselves? Because the kernel does not compile on my computer.

@Androthan is working on CM11 for the 4.2. Compiling just the kernel isn't enough, you'll need a device tree of the 4.2 made for CM11 and build a ROM with that.

Actually bluetooth isn't working, so I can't tell you.

The kernel source for the 4.2 player, from my github account, are still under constructions and won't work.
And, of course, you don't need to compile it yourself.
I'll start with porting to 4.2 when the build for the 3.6 is a lot more stable.
BTW, the player 4.2 is off-topic here

I'll try to get it to 1.2 GHz (I already know what to do). But I'll to do when CM11 is a lot more stable.
1.3 GHz seems to be a bad idea, it could burn out the cpu and drain the battery

No problem, but I think it's better to add a new frequency entry, not change the 1000 Hz to 1100 or 1200 for a better cpu throttling.
Like this {300, 600, 800, 1000, 1100, 1200}
EDIT : can we have in the future (priority for wifi and video playback) add more governor ? (interactive, smartass, ...)

It's very difficult to add a new frequency entry but I'll try my best.
Yes, I'll add some governors later, when everything is more stable.

I speak a lot, but I don't now how it's difficult because It's too hard for me =P
The bootanimation is kinda big for our screen. Maybe we can resize it?
Also, the home button in US version doesn't work.
Android 4.4.3
***Android 4.4.3 is out***
Google released the Android update 4.4.3. This update contains mostly bugfixes and improvements (Read more here: http://liliputing.com/2014/06/whats-new-android-4-4-3-kitkat.html) Don't expect any new features with this update. CyanogenMod is currently merging Android 4.4.3 into CyanogenMod 11, so we have to be patient. As soon as this is done, I'll update my local source code.
Expect Alpha 3 in the next 4 to 5 days.
Hello,
Thanks for the work to port Kitkat on the Galaxy Player.
Until a more stable version, is it possible to install ClockworkMod 6 and keep the stock rom (2.3.6) ?
This will permit to root the device by flashing superSu from ClockworkMod ?

Sorry but this isn't possible and will end in a soft brick.
Thanks @Quentinga & @Androthan, you saved me from making a stupidity
I keep an eye on this rom and will test soon.
Does music/video playback work on Alpha 2 ? (not able to use the sdcard space and Apollo crash everytime)
Phone feature is enable like in CM 7.2, or it's disable? (It is)
EDIT: (07/06/2014)
1) If the player is plugged in and switch it off, it will restart.
If, however, is not connected, then turns off simply.
2) In alpha2 there isn't the performance menu in option.
Any news with wifi module ? the awesome @zaclimon can't help you ?

[Q] Samsung Galaxy S2 i9100 - EXTREMELY HOT - which kernel/rom would be best?

I saw tons of similar topics, tried many solutions but any profited.
I use kernel cm 3.0.64
tried CyanogenMod 12.1 (Lollipop)
currently using : CyanogenMod 11 M12
CPU Temperature while doing nothing : 30-40 C
CPU Temperatura with GPS + Maps + Wifi - even 77 C !!!
I need to change the ROM, because I have problem with GPS in my C11M12 (tried changing gps.conf and other solutions but didnt help).
I downgraded from CM12 (Lollipop) because I had GSM Service problem and also available fixes didnt help. On both ROMs temperature is similar
As we all know that is common problem with S2 I want to check other ROMs and post my recommendation to particular ROM+kernel for other users.
Which do you recommend me to start with?
PS
As I understand the result of high temperature CPU is extremely battery drainage. Yesterday I started to charge when battery was 10% and after some time while charging and using was .... 7%

CPU / GPU change to Perfomance mode?

Hello all,
how can i change the CPU/GPU mode to perfomance? should i root my phone for this? Sorry if this is a newbie question.. i already saw in some threads here ( benchmark thread ) that some user got better results by changing these to perfomance. also its better for gaming on my opx.
thank you
As far as i know, yes.
You need root to use Kernel Apps, like Kernel Aduitor.

yes, root it and install kernel auditor to change settings. Or install custom kernel(blu_spark is available and its good) and tweak accordingly and carefully.
But be cautious, changing to something you don't know may render your phone to be useless/boot loop or brick. Do only the changes you know.
