hey thanx a million andrei... 25.3 is super AMAZING!!!! absolutely perfect.... i've been using it from de time u uploaded... 10 hrs now with wifi connected most of the time and screen on time of about 2hrs 10 mins and my battery percent is still at 58% and I've been using 3g too for a while in between... AMAZING!!! u're a genius mate... hats off to u :cowboy:
[Galaxy S III Original Android Development] AbuYahya:
My idle time battery is good.

Is it possible that those who have problems have the twDVFSapp enabled which is affecting the CPU deep sleep or some other CPU parameter. Try disabling and see!
[Galaxy S III Original Android Development] Steve_max:
Check the "Alarms" tab of BBS.
[Galaxy S III Original Android Development] ArbiterGR:
Interesting, i will check that. Currently i'm on 4.4% per hour for no reason and nothing suspicious on BBS. Will try that.
[Galaxy S III Original Android Development] hanhav:
I have it installed.

It would show in BBS if it was media scan, have had that before too.

Android there with 84 wakeups. I´ll check more.

Thx for suggestions.

Edit: I think the reason was a live wallpaper I installed yesterday or the day before.

Changed it and rebooted. Tadaa, deepsleep came :)

Sorry for bothering and offtopic.

Just thought it would be kernel related...
[Galaxy S III Original Android Development] Carl.Brand.87:
Andrei,

Are you still running these undervolts? I know you can identify the chip by looking at the table but how do i find my stock volts?

Are the volts set in /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table the values i should check in the ASV table?

Also is it possible to find the grade on the GPU?

Also no battery issues here. 19 Hours, 14 minutes - 4 hours, 32 minutes screen on.

Most of the screen on spent playing Radiant Defense :)

Thanks
[Galaxy S III Original Android Development] yhrn:
I'm on 25.2 (haven't upgraded to 25.3 since the changes doesn't matter to me) and see nothing strange with the battery life. In fact, everything is working great.

I really hope people will not turn this thread into another "this kernal stops my deep sleep" thread, which is basically what happened to the Siyha thread. Please just check BBS and use the BBS thread to discuss your findings. In 99.9% of the cases the problem will not be kernel related. Even if you think that everything is exactly the same except for a new kernel version some other little, subtle thing might have changed anyway (complex devices we have these days...)
[Galaxy S III Original Android Development] ArbiterGR:
You're right, on my case atleast. I erased the batterystats file and "recalibrated" it and the problem is now sorted. Something propably corrupted it. I'm back to 1.4%/h now.
[Galaxy S III Original Android Development] nfsmw_gr:
Andrei you said

"Although I might still be able to get one or two steps out of the upper middle frequencies, I spent several hours testing trying to find my voltages and it is annoying and tedious work, and I stopped at the above values. My chip is being attributed ASV5, so middle ground in terms of quality of the chip."

Where can i see what chip quality my phone has?

Also what's the changes for 25.3?

I searched but i can't find anything specific...thanks.
[Galaxy S III Original Android Development] AndreiLux:
For now, compare your stock voltages to the default ASV table in my repository. I'll make the ASV level visible in some future version.

As for the change log, consider what Freddy Mercury sang about: "Open your eyes and see". It's right there in the OP. If you don't have any issues, there is no point in upgrading the minor hotfix versions anyway.
[Galaxy S III Original Android Development] danielsf:
I just had a look, I am also ASV5, and my custom voltages are:

200 @ 675mV

300 @ 725mV

400 @ 750mV

500 @ 775mV

600 @ 825mV

700 @ 850mV

800 @ 900mV

900 @ 925mV

1000 @ 950mV

1100 @ 975mV

1200 @1000mV

1300 @1050mV

1400 @1100mV

and I don't overclock the cpu and have had no instability with these values at all. And for the GPU I have, 160@775mV, 266@800mV, 350@875mV, 440@950mV, 533@1000mV

I have stress tested all the gpu frequencies with those voltages as my max frequency, and those are the lowest I could go without any artifacts. Sorry about this post, just curious how much the tolerances for ASV5 vary by. :)

Sorry for my noob question, but how can I use this script? Can I just copy this into a notepad txt file, edit it as I want and put it is at my init.d folder?

Thanks!!!
[Galaxy S III Original Android Development] :
1. notepad++

2. get any init.d script and delete everything inside with notepad++, of course

3. copy and paste the script you want

4. put it on /system/etc/init.d with rwxrwxrwx permissions

5. done

Hi,

I have nothing to add to marcellocord's instructions but I posted an updated version on the script a bit later. Look at this post.
[Galaxy S III Original Android Development] ctrlaltdel:
Hi,

I am on 25.3 and I am not able to change the Gpu frequency using init.d script which I am able to do so with 25 and 25.1

My script as below

#!/system/xbin/sh

su

echo 640 > /sys/devices/system/gpu/max_freq

echo 108 > /sys/devices/system/gpu/min_freq

I tried to add sleep 60 before echo but still no luck. If I run the echo command in terminal, I can make the change.

Is that something has changed?

Apart from this, the kernel is great!

Thanks.

init script

Thanks for your great work!

Everything rocks, no battery drain on the last wamman lite.

The only problem which i got it is with init script for Gpu undervolting.

I am using the following script:

#!/system/bin/sh

echo 54 650 > /sys/devices/system/gpu/volt_table

echo 108 700 > /sys/devices/system/gpu/volt_table

echo 160 750 > /sys/devices/system/gpu/volt_table

echo 266 800 > /sys/devices/system/gpu/volt_table

echo 350 850 > /sys/devices/system/gpu/volt_table

echo 440 900 > /sys/devices/system/gpu/volt_table

echo 533 975 > /sys/devices/system/gpu/volt_table

On boot It does change just the first two voltage values automatically , leaving the other voltage values untouched. If i run it manually it does work with all voltages.

Could you please help me?

Many thanks in advance
[Galaxy S III Original Android Development] nfsmw_gr:
Woohoo,ASV7 cpu here!

No wonder why i could undervolt so low succesfully! :D

Could anybody give a little howto for undervolting and scoobydoo sound with scrips in init.d ? I used siyah and stweaks till now.. and i dont want to damage my s3 when trying some stuff..

Hi,

i just want to say thanks for your work!

I came here after my stock jb rom stops working with my car dock.

I have a question regarding the car dock mode. when i put the phone in the car dock s voice opens, is there a mod or a tweak to stop that?

simply launching the landscape home screen would be enough. i am not sure that this behaviour is managed by the kernel.
[Galaxy S III Original Android Development] yhrn:
For scooby have a look at the script I attached in this post. The comments in it should make it easy to use for anybody that has used STweaks as they are based on the STweaks descriptions.

Just modify the values and uncomment the settings you want to change. Then rename the file to something like S98scoobydoo (no file extension), push the file to /etc/init.d/ using some root enabled file manager and change the permissions to -rwxr-xr-x. Reboot and your done.
[Galaxy S III Original Android Development] dschense:
Okay,.. i did like you told me and everything seems to run perfekt..

Could you also tell me how to undervolt cpu and gpu properly?

Whe i was using siyahkernel i did uv 100 for cpu and gpu...
[Galaxy S III Original Android Development] yhrn:
Sorry, I have not used scripts to undevolt - I use SetCPU to undervolt CPU. Voltage Control should work as well. However, if you want to use scripts only or want to undervolt GPU I guess you'll have to search the last couple of pages of this thread or maybe somebody else can help.
[Galaxy S III Original Android Development] erto90:

Get your stock voltages from sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

Compare them with this

Match it up and that will be your CPU
[Galaxy S III Original Android Development] mariosraptor:
I have asv4. So? This are the stock voltages that i see
[Galaxy S III Original Android Development] moro30:
i have asv4 too :( what are meaning? my cpu is limited?
[Galaxy S III Original Android Development] AbuYahya:
I have V.N.ASS.

V=very N. =Nice.

ain't you all glad I shared that with you all.*sarcasm*

I hope you get the msg before we flood the thread.
[Galaxy S III Original Android Development] Carl.Brand.87:
Well its limited in a way that you couldn't overclock/undervolt as much as the higher end ones. ASV7 by default already has lower voltage than say ASV4 so you could push it further thats all.
[Galaxy S III Original Android Development] AndreiLux:
There is a difference between uninformed users asking questions and idiotic replies like these. Please stick such messages up your very nice ass next time, because they're half of the problem. If somebody posts something silly, just ignore it and be done with it. I don't want nor need community policing in here.
[Galaxy S III Original Android Development] lokhor:
I have ASV3 :(
[Galaxy S III Original Android Development] rowlers:
can I assume this has to be done before you actually perform any UV. Mine reads the voltage that I have set via setCPU, so I can't compare. Will a reflash of the kernal reset them? Or will removing setCPU reset the voltages?
[Galaxy S III Original Android Development] AbuYahya:
My apologies, I was abit hypoglycaemic at the time!
[Galaxy S III Original Android Development] bazsoczi:
If you uncheck "Set on boot" in SetCpu and reboot, the voltages will revert to stock, and you can check.

still seems to respond well to uv tho...:fingers-crossed:
[Galaxy S III Original Android Development] bigr1979:
Did you get this to work ?

I have just updated to latest wanam rom, also updated perseus from 25.2 to 25.3. I made an init.d folder and put my scripts back, the scoobydoo, max processor scaling and cpu undervolt ones are fine but the gpu undervolting script isnt having effect anymore (apart from the part that sets max gpu to 533mhz)
[Galaxy S III Original Android Development] erto90:
what mean, in know bugs, the audio problem? and how it manifest?

Yes, Perseus have swap support.

[Galaxy S III Original Android Development] andreasy:
I have noticed that an android process (migration/3) gives cpu spikes very often. Now, I'm no Linux expert or something but I've read that it's scheduler related so I'm just reporting it just in case it helps.
[Galaxy S III Original Android Development] kart_y_26:
You can check if theres anything wrong with the script using scriptmanager from the market. Im on 25.3 and the gpuscript i have runs fine, also im pretty sure you don't need scripts to change cpu voltage and frequency, apps like setcpu will do the job fine.
[Galaxy S III Original Android Development] francescozanghetta:
No unfortunately,

I run that script manually by linux script handler and it works like a charm. On boot it just changes the first two gpu vltage value and i don't know why. Any suggestion? Help please

Many thanks
[Galaxy S III Original Android Development] edgarf28:
Caution: I just discovered that the BestMultiTaskingFix doesn't work properly with this kernel!

The minfree & adj values aren't applied in combination with this kernel...

When I flash the Siyah kernel, the minfree and adj values were applied correct.

Can you look at this maybe, Andreilux?
[Galaxy S III Original Android Development] bigr1979:
Hmm. I thought I would try and flash back 25.2 as that was working before but not working on 2.5 now either, i used to be on omega and hasnt worked since being on wanam, dont know if that has anything to do with it....

any way to make it happen without factory reset?
[Galaxy S III Original Android Development] nfsmw_gr:
Stop using the kernel or the script mate.

It gave me lags when i used it(latest version) and i unistalled it right away,it doesn't do anything good,except the lags i haven't seen any difference...

Maybe you need to flash siyah again and disable dual boot..?

Just saying..

Perseus doesn't support dual boot,that may be the root of your issue...

undervolting

Hey AndreiLux,

would you suggest undervolting or is it unnecessary????
[Galaxy S III Original Android Development] erto90:
how i can check if undervolting, in GPU, has been applied?

@psyntific : undervolting save your battery and keep phone colder :cyclops:

because i put ( in a script in init.d folder)

#!/system/bin/sh

echo 54 650 > /sys/devices/system/gpu/volt_table

echo 108 700 > /sys/devices/system/gpu/volt_table

echo 160 750 > /sys/devices/system/gpu/volt_table

echo 266 800 > /sys/devices/system/gpu/volt_table

echo 350 850 > /sys/devices/system/gpu/volt_table

echo 440 900 > /sys/devices/system/gpu/volt_table

echo 533 975 > /sys/devices/system/gpu/volt_table

but under sys/devices/system/gpu in volt_table, values are differents

[Galaxy S III Original Android Development] erto90:
and how you solved? i was reading your posts but haven't found a way to solve..

i'm sure permissions are right!

I made 2 script, 1 for max frequency and the other for voltages, the first works, the voltages one no..

otherwise superb kernel for daily use.i actually thanks for macos file transfer fix.very good improvement.regards
