Gokhan,

Thanks! Will keep try your latest update.
[Galaxy S II Original Android Development] OrangePL:
Hi,

Quick question - do Thunderbolt! scripts (+addons) need to be re-flashed after updating the kernel to new version?

Thanks.
[Galaxy S II Original Android Development] jaher:
Does anyone phone ever randomly freeze somtimes. Mine froze when my alarm turned on and i had to take the battery out. And it froze once on the touch screen lock screen battery out again. I think its to due with siyah maybe not sure do.
[Galaxy S II Original Android Development] :
Birdman you do love your steps don't you:D your like little baby Dj Steps;)

And note to Gokhan...This version so far is by far the smoothest when scrolling and no lags what so ever......feel like i am flying with this version..i shall report battery results in a few days.:) thanks again

yes buddy..there is new scripts by Pikachu in his thread. 2.3.6:)
[Galaxy S II Original Android Development] OrangePL:
Ok, assuming I already had Tb! 2.3.6 installed prior to flashing new kernel...?
[Galaxy S II Original Android Development] :
just flash kernel then and do nothing else..just check with script manager that all the settings for remount and sqlite have there permissions and if they are then you are good to go..also check in your init folder if you have the files that Pikachu mentions in his thread and that is it...or if you still have doubts just reflash:D

Im also having wifi issues. connects to the AP no problem but i cant browse the net. Works fine on stock firmware so i have no idea whats up.....

any ideas?
[Galaxy S II Original Android Development] :
do not if this helps but have you tried changing modem?
[Galaxy S II Original Android Development] VFO:
Seems to be working fine for me with no issues surfing Web on wifi. Out of curiosity what type of router are you using? I am on a NetGear router.

ETA: have your tried resetting your wifi profile? I know this has worked for me in the past when I had wifi issues.
[Galaxy S II Original Android Development] ercxar:
I think it's because of your aggressive UV, try increase voltage like 25mv for every frequency to see if that happens again.
[Galaxy S II Original Android Development] b2rdetor:
can't see any improovements compare 2.6.4 but OC with 2.6.6 gives me bad performance ALWAYS worse than maxcpu1200 because cputrotling limits enabled. seems like my cpu hotter than others or may be other users just isn't test that issue.

think to go back to 2.6.4...
[Galaxy S II Original Android Development] ajvulcan:
I have make a complete wipe and flash the rom again and kernel again and it continues the same... Lulzactive (with default parameters) freezes in one frecuency and doesn´t scale as it should. I'm with miui v2.1.6
[Galaxy S II Original Android Development] seaweeduk:
I'm having the same wifi issues described above, can connect to router and have connectivity with other computers on that router but no internet connectivity.

This isn't the first time I've had this problem I have two routers one is a repeater bridge one is my main router. I can use the internet fine on the main router but connectivity with computers behind the repeater is extremely slow.

In the past clearing dalvick and cache and reverting to an older kernel or a non siyah kernel has fixed this problem but I've tried this and it still remains strangely even on the stock CM kernel :/ Even did a factory reset as last time I had problems this solved it but also no luck this time. This is definitely not an issue with either of my routers.

Are the people experiencing wifi problems also using CM7 or are you on other roms? The rom is pretty much the only thing I haven't tried changing to fix this and I really don't want to have to.

edit: should also add I have tried a variety of modems using KP8 at the minute but had the same problem on KL1

Same here.
[Galaxy S II Original Android Development] :
Check your PM Pingu feet:D:p
[Galaxy S II Original Android Development] seaweeduk:
As others have already said 2.6.6 also seems to stick at 1200mhz a lot and enters deep sleep a lot less than previous versions.
[Galaxy S II Original Android Development] :
For me i had issues with Voltage control and my cpu clock stayed stock frequencies. That meant it stayed 1200-200..It is nothing to do with the kernel it is the app side there is a conflict with...I use No-Frills to overclock and it works perfectly...Regarding deep sleep issues again nothing here...I am using lulzactive governor, Noop scheduler and thunderbolt scripts with the screen scaling whatever you call it add on. My phone seems to be flying.....

Regarding undervolting yes Gokhan said it is fine to combine the two apps but for me i do not like to mix them..I have deleted the voltage control script from init folder and rebooted my phone only by using No - Friils now so over clocking and no undervolting...I shall test battery life and post shots in a few days..But so far this is the best version for me

EDIT: Thought there was a problem with KL1 so i reverted back to KK5 just to check..Again same problem..Voltage control does not want to overclock for some reason but everything else saves fine...Yes i wait for the phone to load up and all scripts to be executed upon reboot before entering VC and still nothing...Not a big issue though i shall wait till Xan fixes the problem
[Galaxy S II Original Android Development] seaweeduk:
Every new kernel release I get rid of my voltage control profile and run the kernel stock for a couple of days before I touch the volting. The issues I'm having are on stock settings unfortunately.
[Galaxy S II Original Android Development] gokhanmoral:
can you just change your cpu governor to ondemand and see if you still have those problems?

I know there are some problems with lulzactive and I will revert some of the changes today.
[Galaxy S II Original Android Development] seaweeduk:
Will reenable my old VC profile and put it to ondemand and let you know if it returns to normal behaviour.
[Galaxy S II Original Android Development] cooldfuzion:
With this new version the battery is drained fast!
[Galaxy S II Original Android Development] Higgins12:
+1

had that already with 2.6.5 and went back to 2.6.4 will stick with it for a while i guess
[Galaxy S II Original Android Development] VFO:
Can report that using conservative governor that voltage behavior is normal. Using CPU spy it shows normal time in state as compared to previous versions. Although it does seem a lot more peppy than before.

Gohkan, can the lulzactive tiger be tamed with the lulzactive app or are the changes made in 2.6.6 overwriting changes made with the app?
[Galaxy S II Original Android Development] VFO:
Double post due to defective Swype user. Sorry for inconvienence.
[Galaxy S II Original Android Development] CamoGeko:
Check your voltage settings.

I flashed 2.6.6 earlier and now using my config version 3 with it. So far not getting this excessive battery drain people keep talking about.

[Galaxy S II Original Android Development] gokhanmoral:
you can use lulzactive app to tweak the governor but some of my modifications made the governor to jump to the max frequency no matter what you set the pump up step. I will fix that part and everybody will be more happy then :)
[Galaxy S II Original Android Development] jaher:
Im on siyah 2.6.6 on wicked rom do i need to flash in battery scripts. To make battery life run longer. Do i need to flash anything on after flashing on siyah to make battery life better or should i just leave it as it is.

Alot of ppl are saying flash other scripts on. Heck i only use set cpu to save battery
[Galaxy S II Original Android Development] XDA mark:
I just updated to 2.6.6 and something is wrong. After my phone rebooted and was done starting itself up, apps still opened very slow. SetCPU showed me 1200 MHz all the time, where on 2.6.5 (and before) it would show 200-500MHz. I entered recovery again and wiped cache and dalvik, flashed 2.6.5 again. But in SetCPU its still showing 1200MHz a lot of the time, so looks like stuff from 2.6.6 is still here.

Anyway, now on 2.6.5 (after a visit to .6), everything seems to have speed up. Youtube opens and plays super fast for my feeling, actually everything seems super fast. Though Im concerned about the battery life.

All is goos though, remaning relaxed and keeping an eye out on this thread and waiting for a new version :)

I love this kernel btw :D
[Galaxy S II Original Android Development] SignalX:
hi

i cant install 2.6.6 on my miui rom! and phone will fall into boot loop!

this is the first time!!

there was no problem with older versions!

can anyone confirm this pls?

anyway, back to 2.6.5 for now

cheers,

SX
[Galaxy S II Original Android Development] xcarecrow:
I usually use ondemand, but now i'm trying lulzactive in 2.6.6 version and i must say that is working perfect, and no issues with wifi never, and deep sleep perfect too. I never had problems with any of your kernels, keep your awesome work gokhan, i will make you a donation.

thanks!
[Galaxy S II Original Android Development] Crazy-Silver:
Gokhan when can i use your kernel on cyanogenmod9?

From my Samsung Galaxy S II With CyanogenMod 9
[Galaxy S II Original Android Development] tolis626:
Hey Gokhan,first off,2.6.6 is running perfectly,as expected after all.I only have a problem with time in state stats not showing anywhere(CPUSpy,SetCPU,SysTune etc),but it remains to be seen whether it's kernel related or not,so don't count this as an issue yet.

Anyway,I had a question I wanted to ask...Would it be possible to overclock our RAM chips?Not that I'd expect too much from it,but it wouldn't hurt to try,right?Unless you're planning to overclock the bus first.Or unless you're planning to not let us overclock anything else. :p
[Galaxy S II Original Android Development] cmangalos:
To answer your curiosity, i have used to wifi. First is from my router, the other one is via connectify (using windows7) laptop. Both not working for 2.6.6, upon reverting back to 2.6.5 it worked. I also tried to reset everything. Ipad is working on those wifi's so i believe i got a kernel problem (2.6.6)
[Galaxy S II Original Android Development] veyka:
I would imagine when we get kernel source for ICS.

Also, wifis working fine here, always has, Netgear N600 DGND3700 (the adsl router one).
[Galaxy S II Original Android Development] barondebxl:
As far as im concerned 2.6.6 is perfect. i dont mess with any OC/UC apps tho.
[Galaxy S II Original Android Development] mabmed:
Gets bootloops after flashing via CWM.. Solves after flashing via Odin.. Any idea?
[Galaxy S II Original Android Development] tolis626:
Yes,flash through Odin instead.Simple,right? ;)

You can also use DarkyROM tool or,even better,Chainfire's CWM app(Not CWM recovery!) to flash the tar version of the kernel via the "Flash Kernel" option.
[Galaxy S II Original Android Development] Café King:
Flashed the zimage of 2.6.6. via HC-kTool and it resulted in a boot loop as well...

/CK
[Galaxy S II Original Android Development] tolis626:
Tried with the .tar instead of the ZImage?Maybe something goes wrong during the decompression.Else,redownload.

As a last resort,you may try wiping dalvik cache.Although it has absolutely nothing to do with kernel,something else might be clashing with it and it may help.It most probably won't though.
[Galaxy S II Original Android Development] N6666661:
Can someone tell me what are the SiyahKernel 2.6.6 default GPU clocks/voltages?

and also plz what are the defaults GPU thresholds?

thanks
[Galaxy S II Original Android Development] Simba501:
Just remove boot settings, reboot, and observe.

Sent from my Galaxy SII
[Galaxy S II Original Android Development] N6666661:
no you can't : tools like Tegrak OC or Voltage Control only list 2 frequencies where Siyah has 3 - plus none of them gives thresholds values.
[Galaxy S II Original Android Development] PedroMRP:
Why using apps when you can with a Terminal check the gpu values by doing "cat /sys/class/misc/gpu_clock_control/gpu_control" ?
[Galaxy S II Original Android Development] N6666661:
ah! nice tip I will try that.

EDIT : obviously it didnt return the voltage :(
[Galaxy S II Original Android Development] PedroMRP:
"cat /sys/class/mic/gpu_voltage_control/gpu_control"
[Galaxy S II Original Android Development] N6666661:
no such file or directory :(
[Galaxy S II Original Android Development] PedroMRP:
Sorry my mistake...

You are the man!:D

thanks a lot!
[Galaxy S II Original Android Development] Holgott:
For me 2.6.6 works perfect overall. Normal state times with most times in 1200Mhz state, but thats no prob for me. When reading or smthg like this phone seems to stay in 200Mhz state. For me best kernel after 2.5.1GT release. Using stock sio with lulz 200-1200 Mhz.
[Galaxy S II Original Android Development] buxz777:
love the kernels etc and the work done to them but 2.6.6 is also keeping my phone at higher frequencys when idle

mine seems to be sticking at 1.4ghz quite a bit

i use smartass v2 via set cpu

i haveny noticed my speeds sticking like this before on siyah kernels so thought id mention it here

i know its not much help but others seem to have the same troubles as well so thought it was worth mentioning it

thanks for all the hard work and i hope your all having a nice weekend
[Galaxy S II Original Android Development] JmPTaz09:
Just a note that 2.6.6 working flawlessly here with lulz, sio and a small uv. No wifi issues at all. Good work!
[Galaxy S II Original Android Development] xavihernandez:
Hi! Thanks again gokhan!

I have noticed like you peeps that governor lulzactive scales frequency to 1200MHz. I have tried with ondemandX (my favorite since it has been added) and frequency does not scale too high. I don't know if it's a normal behavior or if lulzactive has to be fixed I only wanted to give a feedback.

(I have checked CPUSpy and refresh the list for sometimes to have those infos)
[Galaxy S II Original Android Development] Piemo:
Hi,

just a question. If I remember right the Sammy ROM possibility to connect a USB drive to the microUSB port is something "written" in the kernel.

Is possible to add it on this Kernel so also CM7 user can use this feature?

Thanks in advance

Hello I just wanted to ask whether thisbos good battery life for heavy usage(3 hours of south park and other games.)
[Galaxy S II Original Android Development] ajvulcan:
I have problems with all governors, overall with luzlactive. They are always in high frecuencies (if not stuck in 1200 Mhz or other). If I modify lulzactive parameters it seems that have no effect or very little on lulzactive behaviour. Now i have to tweak convervative and rarely goes to 200 Mhz. The phone doesn´t normally enter in deep sleep and the battery is draining a lot.

No wifi issues or other, but thats important, in previous kernels like 2.6.5 it didn´t happen.

Some people here says that it works perfectly for them... I use miui, maybe is an issue with this kernel here.

I only want my kernel scaling up very fast with great performance, but in moments of low load scaling down to 200 Mhz and keeping the frecuency more o less. I think I archieve that with some teaks of lulzactive in 2.6.5 (the performance in 2.6.4 was amazing but when i was some time playing a game the phone got extremely hot and shut down automatically sometimes with some strange and disturbing electric sounds).
[Galaxy S II Original Android Development] stevehkim:
GoKhan, I believe ondemandx is a interactive based governer. So would this governer have some issues as well in 2.6.6? I've tried using ondemandx and your default settings as well as pikachu's thunderbolt scripts and deep sleep seems to be an issue here. My wifi is ok. It's just deep sleep. Like's to hang around 200 mhz or so when screen is off more than deep sleep. And nothing out of the norm in bbs. I flashed back to 2.6.4 for a few hours and deep sleep levels were at 90% within a 40 mins. span. Either way doc I'm sure you are already on it. Just leaving some feedback boss.
[Galaxy S II Original Android Development] incubus_fr:
I'm on 2.6.6 for 17 hours with ondemandx and no deep sleep issues (actually no issues at all).

Not using thunderbolt btw...
[Galaxy S II Original Android Development] stevehkim:
really? sorry not being sarcastic just wondering what could be the cause. are you checking with cpu spy?

tweaked - by me

[Galaxy S II Original Android Development] runedrune:
Don't you think it would make more sense to believe ondemandx was an ondemand based governer?

I've flashed Thunderbolt 2.3.6 - could anyone share a 'tried & tested' stable + battery saving VC and GPU settings that work best with Thunderbolt?
[Galaxy S II Original Android Development] stevehkim:
Crap my bad guys. typo. I was thinking about something and mistyped. ondemandx=ondemand. either way did some more testing for deep sleep from 2.6.6 and 2.6.4 and definitely something is up. so maybe it's my phone that can't handle 2.6.6. it's all good cause GK always makes up for it in his updates.
[Galaxy S II Original Android Development] tolis626:
@stevehkim

Regarding your issues with deep sleep,did you by any chance install Tegrak Overclock?
[Galaxy S II Original Android Development] stevehkim:
tolis. no. just use setcpu and voltage control. with setcpu only use it for cpu scaling. voltage control for voltages and io scheduler. i didnt change anything from 2.6.4. just flashed back to 2.6.4 and deep sleep is already at 85%. within 15 min time span. where as 2.6.6 after 15 mins would be 30% deep, 30% @ 200 mhz, and some other % @ 800 mhz. i left it for an hour and deep sleep only rose to 40%. and all other frequencies were used as well.

tweaked - by me

kernel - siyah the og

rom- me you eeee.
[Galaxy S II Original Android Development] N6666661:
Regarding ppl that have their CPU sticked to 1200mHz or other frequency I think I have find something.

When I first installed 2.6.6 over 2.6.4 I have kept my init.d script I have never face any issue with deepsleep or bad working CPU frequency switching.

Then I have deleted my init.d script and reboot the phone : frequency was 98% of the time at the top default frequency : 1200mHz with no deep sleep at all!

Then I put the script back, rebooted : bingo!:D everything was fine again : deepsleep as it is supposed to be, and a very well scaled CPU frequencies.

I hope it can help some of you waitting for 2.6.7:cool:
[Galaxy S II Original Android Development] fusionjack:
Just wanna sharing my experience using 2.6.6 with lulzactive. Overall I don't have any problems with 2.6.6, but as I used Skype's voice chat with screen-off, lulzactive scaled down to 200 MHz which I think too low for voice chat. As result, the voice didn't clear enough. As I change the governor to ondemandx, it scaled down to 500 MHz and it worked really well for voice chat.

I'm not sure whether this relates to 2.6.6 or overall with lulzactive. I don't use any scripts and don't set screen-off profile.

From my opinion, it seems that lulzactive is not smart enough as ondemandx. I know that lulzactive is a wild governor :)
[Galaxy S II Original Android Development] tolis626:
****...Well,I don't know what's wrong with my device,but since I installed 2.6.6 everything that shows time in state for the CPU doesn't work.CPUSpy shows no frequencies,just deep sleep state at 100%.SetCPU fc's when I press the "Time in state" button.SysTune just doesn't react,it acts as if nothing is wrong,but doesn't show time in state.I don't know wtf is wrong,but I don't really care that much.

Why doesn't anybody uses BFQ+Conservative combo?

I expirience stability, no lags or freezes or reebots and good battery life even with some extreme undervolting.

I get almost 2 days with 6 + hours screen time(not that i need it).
[Galaxy S II Original Android Development] tolis626:
Nope,it's not related.Thanks for trying to help though. :)
[Galaxy S II Original Android Development] JmPTaz09:
I use conservative and sio
[Galaxy S II Original Android Development] XDA mark:
After reading your sig I undervolted a little bit more. I just made one -25mV step in my life, so when I saw your setup I realised I could go a little more :P

Why are the standard mV settings higher then needed? What happens when you chamge them? The current CPU frequency uses less energy? Resulting in a possible shortage and rebooting your phone?

Just intrested in learning better what I am actually doing :)
[Galaxy S II Original Android Development] Simba501:
Because every device is different. Considerable undervolting that works well for you may cause instability for me. The stock values work for every device.

Sent from my Galaxy SII
[Galaxy S II Original Android Development] XDA mark:
Its weird that every device is different. They all have the same processor and stuff I would think... though I have seen the same devices be able to do something and other not. Eh, let me not bother you guys with this stuff. I believe you ;)

Edit:Veyka answered my question. Thank you!
[Galaxy S II Original Android Development] veyka:
Because cpu fabrication is not a perfect science, every chip is slightly different, and need a slightly different amount of power todo the job, they grade chips, and the better the chip the lower the stock voltages, but at the same time they still want it to be 100% stable within defined limits.

That means they are never going to be to aggressive, as end-users who are inclined to tweak our phones, we can push the envelope, but we have to understand the risks.

Basically, it may SoD (sleep of death, never wake up from deep sleep), or it may be randomly unstable, reboot, crash, you play the game you take the risks.

Undervolting should never dmg your hardware, it may even make it last a little bit longer (less power, less heat, less dmg over time), but the reason we do it, less power used it more power left in the battery to help it last longer.

And for the fun, dont forget the fun!

hi gokhanmoral

why are you remove intellidemand again from 2.6.6? this is the best battery saver for me so far.. I stay on 2.6.5 and I hope u will put it back again on yours next release..

intellidemand+undervoltage give me 4days+ battery time.
[Galaxy S II Original Android Development] Jokesy:
Which of these CPU Governors give best battery life? Lulzactive or Ondemandx or Smartass V2?

I need a quick response because i just noticed my favourite Governor i.e. Lulzactive always scale to 1200MHZ in about 99% of use. Strange! So i need a good alternative.

Thanks
