Best working set for me is ondemand with bfq..100-1400 oc..I'm not using setcpu only nofrills..also I'm using juice defender with a setting that it has for cpu were I can set in idle max to 500..all these together seems working well..smartass gives me a little lag...also

I had problems with wifi connection in previous beta but with beta 3 the problem just gone..very very promising kernel! Keep good work!

Hello gokhanmoral i noticed that if i use the touch screen my cpu is using 1000 mhz frequency and not 500 mhz that stock kernel is using. I think that this can affect battery life.
[Galaxy S II Original Android Development] Остап:
U were right. I've tried it an battery looses 0.81% per hour. Same thing.
[Galaxy S II Original Android Development] ehmi:
When i change charging current with the echo comand the usb charging value is also changed to the other values:

example:

changing 1000 1000 450

The current file shows 1000 1000 1000
[Galaxy S II Original Android Development] :
Yeah, I think I'll go back to ondemand also, don't like the lag in some apps.
[Galaxy S II Original Android Development] tonysac:
Yep, with ondemand no lag at all!

I removed all new governors as I don't have time to tweak them all. I will add them one by one later...

I have tweaked the smartassv2 governor a bit.

I will release rc1 today

so there will me no new features but only tweaks until I release the final.

Guys I don't kwon why... but tried everything...

Clearing cache and dalvik

Fix Permission

Flash via Odin

Flash via CWM

Flashing an insecure kernel then apply root with scripts or with superoneclick

...

Everytime I flash your kernel (tried 1.7beta3 also) I loose my root... :(
[Galaxy S II Original Android Development] gokhanmoral:
Try to flash this with cwm: http://db.tt/sXuKW18z

I always keep it in my sdcard in case I need it.

I dont know why you lose root but that should give it back.

[Galaxy S II Original Android Development] kwerdenker:
Just a quick warning for those who might use my init-scripts: i need to adapet the UV one for the new steppings in beta3. You should deactivate/delete the script before flashing beta3 or you'll get in trouble. I'll post the new one as soon as I find a more robust way to determine the steppings in the kernel.

Sent from my secret moonbase via space carrier pidgeons
[Galaxy S II Original Android Development] gokhanmoral:
why is it needed?

I just changed 1600mhz to 1504.

1504 can run on a higher voltage.

there is no new step.

I reverted it back for the rc1 anyway.
[Galaxy S II Original Android Development] kwerdenker:
In the current version I explicity check for a 1600mhz stepping and do not count the number of steppings. That sufficed for alle the kernel I used so far but this change broke. But I guess this is a good thing, since the script should be really more robust and I also wanted to make it fail safe, so it rather does nothing when faced with an unknown situation.

Gokhan... noob question, what is the difference between tar. and cwm. flashing? any + or - ?

p.s. sorry my english :o
[Galaxy S II Original Android Development] BoneMo:
just a try--- does Voltage control have root permissions ? have you tried nofrills or setcpu whether it persists ?
[Galaxy S II Original Android Development] bartje885:
Hit menu button and choose Save as boot settings :)
[Galaxy S II Original Android Development] gokhanmoral:
no difference in functionality. the only difference is the flashing method.
[Galaxy S II Original Android Development] gokhanmoral:
it may be related with the decreased delay (from 30 secs to 15) before running the init scripts.

there is something which sets the higher level to 1200MHz during the runtime.

I don't know what it is. does anybody have any idea? is it a service running during boot? a samsung featurish-bug?

I will increase the delay back to 30 secs in 2.1

[Galaxy S II Original Android Development] cloak:
I have made the upgrade from 1.8 to 2.0 now.

I was not positive about the idea building one kernel for standard and cm builds.

I am using the Batista rom.

V2.0 is amazing!

Applications running much faster now. For.i the new Google market app is starting nearly instantly now. Also sygic navigation is running as a rocket now! Gps fix instant sound quality is heavily improved. It seems battery consumption is improved too. For me it seems having a new phone!

I do not know the 2.0 trick but you are a master!

Flashed 2.0 yesterday before going to bed, here are the results in wake mode which is not that bad (wifi + 3G + sync for mail) :) :

-100% until 3h10.

-100% to 95% in 8h30.

the fuel-gauge chip on our phones do not support it, or let's say it doesn't need it.

so, calibrating battery is just a placebo...

don't waste your time calibrating the battery again.
[Galaxy S II Original Android Development] newHere:):
no...

i flashed via the CWM application..

not from the recovery... and it was stuck on the "Flashing kernel..."

after 6 minutes of waiting i had the guts to take the battery off...

i pulled it back on and hoped for good respond...

and the device turn on normally and says Siyah 2.0 is installed...

now i dont know if i have to mount it again and how :p
[Galaxy S II Original Android Development] gokhanmoral:
it may be a bad download.

redownload it. if you cannot boot your phone use odin to flash tar.

deepidle

I read a lot of messages about deepidle and received several PMs as well.

our chip supports deep idle mode.

and the good news is that it is already implemented :P

I've just checked the source code and it is called lowpower mode in the source (cpuidle.c).

we may try to tweak it more, but I don't think we will gain as much as 55% less drain.

Gok,

I went from 2b8 with no wifi issues to 2rc2 with wifi issues. Flashed 2final still had issues. Reflashed a few times.. same result. Flashed the modem and flashed cf kernel. Wifi issues continued. Reflashed rom..same. Flashed back to 2.0final, still issues.

Any idea what would cause this? Could it be one of the init.d scripts from first page not playing nice? Everything worked great till I flashed 2rc2.

Seems odd the problem continues even after changing to cf kernel. I guess i'll have to do a full wipe.

[Galaxy S II Original Android Development] gokhanmoral:
if the problem continues after flashing cf-root kernel then it is not kernel related.

try a stock rom. flash cf-root to have root and then flash 2.0 final.

I do not replace anything in the rom, especially after removing rooting support.

Can anyone please confirm for me that if I installed Lite'ning ROM 6.1 XXKH3 and I now want to install the SiyahKernel v2.0 do I have to revert back to CF-Root XX_OXA_KH3 then flash my phone with SiyahKernel and then reinstall Lite'ning 6.1 or can I just put SiyahKernel on my phone with Odin now?
[Galaxy S II Original Android Development] Остап:
No confirmation. Just install Kernel.
[Galaxy S II Original Android Development] d3l1:
I had the same issue this morning with CWM app. I downloaded the .tar, flashed it via CWM app and the phone froze saying "Flashing Kernel". I removed the battery after five minutes and didn't try to boot the phone but went to CWM Recovery myself flashing the zip (glad I downloaded both just in case :) ) and it worked. Took a bit longer to boot due to wiping cache/dalvik cache but it works fine for 4 hours now. Did a second reboot just to be sure but all seems fine now.

Maybe a bad download (dl via tapatalk).

How to do I change the i/o schedulers if I use daemon controller? Sio is the default and a good choice? Daemon Controller should be the only app, running no-frills, too, will cause issues right? Is there any change to recommended governors in v2.0? I used wake(ondemand 200/1200) and sleep(conservative 100/200) with virtuous_oc on v1.8 and kept the settings for now, though homescreen seems to be a bit laggy since upgrading.
[Galaxy S II Original Android Development] shrooms90:
what rom are u on? i just noticed it for the first time, wifi just quickly dropped and reconnected. im on criskelo v25

But i have a problem with battery :

Every morning, after booting, my phone power off over the night, m'y battery drops up to 10%!!!!

This is very annoying!

Should i calibrate or what...???
[Galaxy S II Original Android Development] gokhanmoral:
I don't know much about the internals of the fuel-gauge chip.

Since you don't have any way to calibrate, try to use airplane mode next time instead of powering it down.
[Galaxy S II Original Android Development] newHere:):
for me it works fine after pulling the battery off and on back...

i think i will leave it that way and do not flash again..
[Galaxy S II Original Android Development] ram3n:
Wow, you mean I have not to power down my S2 now ? :eek:

Before, I never had this kind of issues, every morning, battery didn't change after powering on.

So, there's obviously something wrong with the battery calibration now ...

Moreover, there are many people posting after recalibrating, their battery were better...

So why can't we not do it now ?

I really don't understand my problem .... :(

So I've been playing with SiyahKernel 2.0 tonight and I've found that in 3D applications, the only CPU governors that seem to work properly are Conservative, OndemandX, and Performance.

All other governors vary from extreme lag to some stuttering in 3D apps.
[Galaxy S II Original Android Development] jsompis:
IMO, It worth to try these step:

1. Boot into CWM recovery.

2. Wipe battery stats.

3. Power Off your phone.

4. Charge your phone until battery full.

5. Power on your phone.

Free App Batteryallibration from market will do it easier with onscreen to-do information.
[Galaxy S II Original Android Development] jim-bo:
Bad idea. All phones reall are that different. For example, at 100MHz, some people report stable at 775mV, other people need to be at 875mV for stability, which is a HUGE variation, more than twice the undervolting in one case than the other.

If you want a set of voltages that are guaranteed to work on every S2, then that's easy - Samsung invested a lot of time and money in finding them, and then conveniently set them as the stock values for you.

If you want to know what your phone can do, then there is no shortcut. You need to go through each and every clock speed, setting it as max on the performance govenor, dropping the voltage one step (25mV) at a time, and running a stability tester for at least 10-30 minutes, for each voltage, for each clockspeed. When the phone starts to crash, go back up one (or two) steps, and that is your safe stable voltage at that speed.

You can expect this process to take you most of a day. If you can't be bothered to spend that much time on it, then you could try lowering the voltage for one clockspeed by one step, then running your phone normally for a day or so, and see if you get crashes. This method will take you most of a month to get all of the voltages to their lowest stable level, and that's assuming that you do manage to crash the phone within the day that you're testing a step - there is every chance that it will be the step from a couple of days ago that falls over, and you won't know without starting again or doing it the long way.

And just for reference, here's some numbers, so you can see the ranges involved

Speed Stock Best Mine
1600MHz 1425 1350 Not stable even at 1450mV
1400MHz 1325 1250 1300
1200MHz 1275 1150 1200
1000MHz 1175 1075 1075
800MHz 1075 1000 1000
500MHz 975 900 900
200MHz 950 775 875
100MHz 950 775 875

The "Best" column was the best figures I saw reported by people when I was first setting my own u/v voltages, so I knew what sort of area to aim for. I'm sure that there are people out there with lower voltages, I only scanned a couple of threads, and it was a while back, now.

As you can see, even on one phone (mine) some of the voltages are as good as I saw anywhere, and others are way up from it, (or not stable at all for 1600), so there is no way anyone can give you a rule for what will work on your phone.

Writing this has reminded me... I ought to re-check my values now that 2.0 final is out, some of them may have moved with the new codebase ;)
