Great work, very smooth even at 100-1000 using Tricky's optimized miui 1.11.11.

Thanks a lot!
[Galaxy S II Original Android Development] KcDaRookie:
I dont have Android SDK installed and can't use adb therefore ^^

Or can you use adb without the rest of the SDK?

I will think about implementing it, but for now I just want to finish it ^^
[Galaxy S II Original Android Development] :
I think beta15 is the best of all. Very smooth, best score in antutu. Lest hope, is good in battery too.
[Galaxy S II Original Android Development] DJ 1:
So what's better,set CPU or no-frills CPU ?

[Galaxy S II Original Android Development] :
Voltage control.
[Galaxy S II Original Android Development] BoneMo:
i suggest that best is Voltage control...so none of them....or no-frills if it is needed
[Galaxy S II Original Android Development] smitna:
Hi, you only need the adb files. Download the tool "SuperOneClick" http://xdaforums.com/showthread.php?t=803682 and look in the folder ADB. On the phone "USB-Debugging" must be set on.
[Galaxy S II Original Android Development] DJ 1:
just to be sure i got the same thing in the market, Darek xan is the Dev of voltage control....yeah?
[Galaxy S II Original Android Development] DJ 1:
cool ok as it says its the lite versio, but didnt notice any mention iof that in the youtube vid on 1st page...
[Galaxy S II Original Android Development] John E Dante:
Beta15 works great, minimal lag and high speeds. Can't even compare to other betas above 6 (at least not above 9). No issues what so ever so far, battery seems fine as well. Keep up the good work!
[Galaxy S II Original Android Development] :
5807 score in antutu. Most than any other siyah kernel, and every other I have try. Checkrom 3.1.1 luzactive governor 100-1200 mhz, uv everything.

Αυτά αδερφέ!
[Galaxy S II Original Android Development] MrPhilo:
Beta 15 is great but I found a problem, I don't think init.d are working anymore. I could be wrong.

Im using voltage control and saved a 'script' created by it to apply at every start, after flashing beta 15 it just restarts back to stock kernel way (On demand, Sio).

I've already wiped dalvik etc.

Hope for a quick fix :)
[Galaxy S II Original Android Development] Radikaal:
2.2b15 is after 30mins of testing perhaps the best kernels ive tried yet. Same/better smoothness as in 2.1.1 (which been the best stable siyah release for for me in smoothness, been a little disapointed with all betas so far up till now).

Also getting the best benchmarks scores ive been having ever at 1200MHz and a Samsung ROM, and SD card read speed has went up by 100% in Antutu and database IO scores in same benchmarks have gotten up quite a bit aswell (got 520 first run, always have had 400 before on samsung roms). Just benchmarks, but still quite a huge boost.

Battery i can't comment on yet. :p

Thanks!! :)
[Galaxy S II Original Android Development] :
Oh and now you can turn off soft key backlight using screen filter app on miui. Wow.
[Galaxy S II Original Android Development] :
Which rom? It works fine on miui. Try disabling media scan on boot using rescan media root app from market.
[Galaxy S II Original Android Development] Guetta1:
Beta15 is a really great !

I love you gokhan, no more jerky video playback, everything super-smooth again ! ;)
[Galaxy S II Original Android Development] KcDaRookie:
Okey, didn't know that.. will look into it in the future..

So first Alpha is ready...

ATM can only generate script, you have to save by hand, but I will work on it tomorrow.. enoug for today ^^

Sources will follow when the tool is able to save ^^

Should flash it by cwm correct?

tried on checkrom and miui ndt,now lets monitor battery :)
[Galaxy S II Original Android Development] KcDaRookie:
Nope, its an executable for Windows.

Unzip and start.
[Galaxy S II Original Android Development] scorpion667:
Best kernel since Siyah 2.1.1.

Smooth, stable and fast.

Smoothness is always #1 for me, even behind battery life and this kernel certainly delivers =).

I was about to go buy the 4s for smoothness before I flashed this =P. Changed my mind now.

Combined with touchscreen sensitivity set to 3 in TouchMove app, it's iphone smooth 8)
[Galaxy S II Original Android Development] the^one123:
Runs smooth like hell with lulz 200:1200. Great build b15 coming from b8.

B15 works fine ! Perfect for me...
[Galaxy S II Original Android Development] mcreego:
Hi Best kernel out there. Could you implement the New voodoo colour tuning module Frome supercurio too
[Galaxy S II Original Android Development] MrPhilo:
MIUI should work fine but Stock Samsung might have troubles.

Might just be me, but we'll see.
[Galaxy S II Original Android Development] _cummoo:
Two words - just fantastic !!!

Beta 15 - Amazing work Gökhan !

Everytime you think there is no increase possible, this kernel shows you there is !:D
[Galaxy S II Original Android Development] mrjeffery:
Serious question, why isn't the screen sensitivity this responsive out of the box from Samsung?
[Galaxy S II Original Android Development] DobermanS:
and even with 100:1200 ... :)

Compliment for the chef

Compliment for the dev, beta 15 is the best kernel ever. Smooth, fast, stable and battery life is to be seen.

Carry on the great work

Beta15 is still sluggish when launching the app drawer with adw launcher ex with lulzactive governor.
[Galaxy S II Original Android Development] smitna:
No problems with stock rom 2.3.4 / B15. I have a few scripts in /system/etc/init.d

Check the folder and permissions. In a terminal window run manually

/sbin/busybox run-parts /system/etc/init.d
[Galaxy S II Original Android Development] gokhanmoral:
try ondemand. it should give better performance.
[Galaxy S II Original Android Development] crypticc:
You should ask this question on cm7 Q&A thread..it's well known it doesn't always backup gapps which means or appears to lose google settings. Not this kernel fault
[Galaxy S II Original Android Development] Annihlist:
Still getting dual indexing from externalsd card. I have about 1000 photos in the external card.

I also got an FC in gallery before. Rebooting fixed the issue however I didn't experience this before the new mount location.

Btw: beta15 withe delay fix
[Galaxy S II Original Android Development] jlevy73:
You still recommend using the 2nd core app? Beta15 is great, no issues at all :)
[Galaxy S II Original Android Development] antiochasylum:
So looks like 15 is the one to flash. Interesting. Might have to finally try it.
[Galaxy S II Original Android Development] crypticc:
Google tegrak touch tune
[Galaxy S II Original Android Development] gokhanmoral:
Hmm then I should also remove /emmc.

I will try latest cm7 next week. Are you having dual indexing with regular gallery app?
[Galaxy S II Original Android Development] jlevy73:
Yeah, Samsung default the touch sensitivity at 15. With TegraK touch tune one can reduce it all the way to 0 for excellent touch response.
[Galaxy S II Original Android Development] scorpion667:
No wifi issues here with CM7 111 and beta15
[Galaxy S II Original Android Development] Annihlist:
Yes this is with the regular app.

I don't mind the ASOP default mounts. However I don't use CWM Manager to backup and restore.
[Galaxy S II Original Android Development] gokhanmoral:
It is optional. Some people do not need second core and they disable one core to have more battery, some needs both cores on all the time... If you need it use it. I just don't use it because I want to monitor dynamic hotplug behavior. If I wasnt working on this kernel I would disable one core and only enable it when I launch games maybe. You have two options for disabling second core: change pmhotplug threshold or use tegrak's second core application. Tegrak's application is more efficient because it disables hotplug code completely which also prevents unnecessary load analysis. You can also use tasker to change hotplug mode by using misc devices in second_core directory under /sys. You need to echo "on" or "off" to device files. You can, for example, disable second core during night and enable it back when the screen is on etc...
[Galaxy S II Original Android Development] navdra:
Me 2. CWM Manager is nice, but causes a headache with it's mounting scheme which is in conflict with lot's of ROMs. Everything that it does can be done from CWM Recovery. Take into consideration to remove it completely if it can't coexist with other stuff.

Ondemand works great, but lulzactive wasn't giving this issue with previous version.
[Galaxy S II Original Android Development] jlevy73:
Excellent suggestions, thanks. So far beta15 is smooth as butter using ondemand. Appreciate all the hard work you've put into this kernel!
[Galaxy S II Original Android Development] gokhanmoral:
I will optimize governors one by one while trying to keep their objective. Lulzactive may be a little slower than ondemand all the time.

On which version was lulzactive working better? Beta14?
[Galaxy S II Original Android Development] bragon2010:
Beta 9 i think..
[Galaxy S II Original Android Development] peachpuff:
Im still on beta8, i upgrade weekly :)
[Galaxy S II Original Android Development] crypticc:
Never really had much of an issue tbh.

Just gets faster and smoother. browser lag on occasional kernel but is obvious redraw issue on graphic intensive Web site, and 15 definitely doesn't have it.

Beta 15 is very smooth ,lulz . Great work

[Galaxy S II Original Android Development] bragon2010:
Can you post the app please? :)

Thanks!
[Galaxy S II Original Android Development] MrPhilo:
All the other scripts are working fine in my init.d (GPU Undervolt for example is working), just that when I reboot my phone my profile that I've setup in 'Voltage control' apps doesn't automatically change anymore, I have to manually set it. I've tried deleting all the scripts and build.prop tweaks i've added, still have the problem.

I'll see what else I can do. Maybe its just me.

Yeah, MrPhilo is also a great dev !

MrPhilo, i'm using your awesome ROM "Simple & Clean 1.3" and all combined init.d scripts are working like a charm here with Beta 15 ! :p
[Galaxy S II Original Android Development] goose2600:
Hi Gokhan!

Also some lags here on cm7 (116) and laucher pro using b15 with lulzactive governor.

Actually all last betas was a little bit laggy in appdrawer (or when scrolling many sms).

Of course ondemand work smooth... and strangely conservative works smooth like ondemand!!!

@bragon2010

Can you try to use conservative gorvernor and let me know if it works smoother than lulzactive?
[Galaxy S II Original Android Development] omegajester:
I've never experienced any noticeable lag... then agaim, I use launcherpro, which stays smooth despite laggy enviroments (most of the times anyways)... just a thought :)
[Galaxy S II Original Android Development] xeq544:
upgraded from b8 to b15. The ondemandX governor behavior seems to have changed. In B8 it always stayed at 100mhz, rarely going to 200 or 500 while idle(screen on) now it jumps between 800 500 rarely 200 and very rarely 100. Any possibility of going back to that behavior ? It was really good.

Anyway... great kernel :)
[Galaxy S II Original Android Development] Radikaal:
im also having lag/unsmooth issue with luzactive. Not a problem thought, but i remember atleast on beta8 and in MIUI ROM it was supersmooth and gave me best benchmark scores. But now im using CheckRom so not fair to compare.

But Ondemand works flawlessy. The best siyah version (and kernel) so far id say for this device (in terms of performance+smoothness) :)
[Galaxy S II Original Android Development] superleeds27:
B15 Best soo far i think.

Although, my battery life seems to be suspect. Think its down to the ROM though. (KJ3)

May switch back to KI4
[Galaxy S II Original Android Development] lemondroid:
Does that mean that B15 will drain more battery?

Isn't less mhz means better battery life?
[Galaxy S II Original Android Development] Radikaal:
no.. i think its just his governor bugging, happend to me sometimes, just set MHz to your min and then up again, or let phone go to deepsleep and it should be gone.

Atleast ondemand is not having this behaviour, when browsing XDA app for 10minutwes im having 90% of the time in 200-500MHz, like it should be. And screen on (idle) always on lowest freq.
[Galaxy S II Original Android Development] jlevy73:
Are you on cognition or stock KJ3? I was getting battery drain with Cognition but back on stock KJ3 + beta15 battery life has been excellent.
[Galaxy S II Original Android Development] superleeds27:
Yeah, Cognition 777 R2.

Thinking of trying the Simple&Clean ROM, (KJ1)
[Galaxy S II Original Android Development] lemondroid:
I wonder what is good battery life for you? :)

I didn't tried Siyah b15 beta yet, But I used to have Lite'ning with Speedmod and over night the battery lost only 1% in 12 hours.

Now I am with MIUI and trying to get the best out of it, After 8 hours already 3% are gone, With 2.1 :/
[Galaxy S II Original Android Development] jlevy73:
If I can get 14-16 hours I'm happy. My day typically consists of 3-4 hours of calls, an hour of browsing, hour of music and hour of gaming (in addition to the normal texts, emails, etc).

Same here, using lulzactive on b15 really laggy..

[Galaxy S II Original Android Development] CamoGeko:
Definitely time well spent. Massive thanks to you and gokhan for the great effort. :D

Beta 15 largely similar to beta 8 on performance, only quite a bit smoother as well. CWM is all in order as well, cyan is cool.

Transmitted from a Galaxy far far away via XDA lightspeed telepathy.
[Galaxy S II Original Android Development] droidphile:
lulzactive and smartassv2 was smoothest on b9. Looking at all the comments, lulzactive lags were considerably less for aosp roms users and more for samsung based rom users.

Best beta is b15 anyway. Might only require minor tweaks on couple of governors for RCs! (More thanks to Gokhan & Kalpik :) )
[Galaxy S II Original Android Development] xBlackDroid:
all working correct,

unclock 800-100 MHz with lulz and run very smoothy, <-- the fist time i see that

BlueTooth, Leds, etc.. works ok

the best beta
[Galaxy S II Original Android Development] tbong777:
Same here...I am happy to get 14 hours, I have the 2000MAH battery on the way, I want the best performance at 12 hours batterylife. I carry and extra battery and charge every night. Performance is more important with a device like this. I have seen three days of batterylife and wonder if they even use the device or make batterylife a "hobby" LOL
[Galaxy S II Original Android Development] cmd512:
Battery does seem to drain faster on my stock KJ3 with beta15 vs beta9. Will need to test further though.
[Galaxy S II Original Android Development] extract1:
Installed Beta 15 today and first thing i noticed was the quick boot time. So whatever you did to speed that up well done!. However i am still experiencing major Lag in Smartassv2 and Lulzactive governor when scrolling in boat browser. This problem doesn't exist in Beta 11 so maybe look at what you did there so you can hopefully fix it up in the next Beta. Once this little hiccup is fixed up you may as well release the final since the Kernel is perfect otherwise:D.
[Galaxy S II Original Android Development] vijaysivakula:

i'm curious about battery life ^.^
[Galaxy S II Original Android Development] gokhanmoral:
lulzactive users: beta8 or beta9?

which one was more responsive for you?
[Galaxy S II Original Android Development] :
B9 for me.

@droidphile thanks for nice private message.. It really made me think :p

I agree that we need more detail (for example I didn't know there was a sharpness settings in CM7 and I don't know where it is... :) ) or to wait until someone else reporting the same problem but please do not post anything to cm thread if you are using this kernel.

if you can reproduce it with cm kernel then post it of course.

Back to beta9 for me. beta15:

1) Drained battery significantly faster.

2) App drawer had severe choppiness with ADW Launcher Ex on lulzactive compared to beta9.

best for battery life is beta 6!!!
[Galaxy S II Original Android Development] cheewaca:
Great performance with B15, very smooth but my problem with coverage come back.

I don´t know why but with some 2.2 betas i have problem with coverage. I tried to change modem version with this and other betas with this problem and it persist.

If i change to beta 6 or other kernel i haven´t the problem. With beta 15 this problem is magnified, in an area where there is little coverage, 1 or 2 lines, phone always stay without it or sometimes show one line but when people call me the phone seems as if off.

There is something in these betas that affect the performance of coverage.

edit:

Stock rom XWKJ3 and kernel with stock values.
[Galaxy S II Original Android Development] goose2600:
For me beta9 seems more responsive (on cm7), but beta8 is very similar to beta9

By the way, on beta15 sometimes conservative is more responsive then lulzactive
[Galaxy S II Original Android Development] TecQuality:
so we need to connect the device with the usb debugging settled ON and run that executable?

ps. i've already installed the ADB tools.
[Galaxy S II Original Android Development] squall_kay:
gokhanmoral, any chance u will integrate mdnie setting into ur kernel?
[Galaxy S II Original Android Development] :
All the betas since beta 10 have a bug in my cm7.

The external sd card cannot be found, read, or whatever. (I'm talking about the one, that you can actually take out of the phone)

In my statusbar I always have the symbol telling me "searching for sd-card" or something like that.

Would be great if you could fix it, i can't use any of the new betas because of this. "Media" (which is caused by this problem) eats my battery alive.
[Galaxy S II Original Android Development] goose2600:
Runnig executable open a window where you can choose your preferred settings.

Then the program will generate the script and you have to copy it to device by hand
[Galaxy S II Original Android Development] navdra:
Do you have "Storage" option in Settings where you can uncheck "Use internal storage"? That will use removable card for apps and data and it should work. At least that's what I have to do with Oxygen 2.3.2
[Galaxy S II Original Android Development] KcDaRookie:
as goose said ATM you have to copy it by hand to /system/etc/init.d

but I will try to implement adb autopush so that you only have to click a button while the phones connected
[Galaxy S II Original Android Development] SilverMist1:
just a feedback; in a 10 hour idle time, in beta6 cpuspy shows 4 seconds at 100mhz and in beta15 cpuspy shows 8 minutes at 100mhz. (luzactive and cfq in both and both in the latest miui)
[Galaxy S II Original Android Development] midreestaj:
Using now Beta15 with lulzactive 100-1200. No lag at all. Great Job by Gokhan.

However I have seen cpu1 kicks in earlier than beta8/9
