Just started using this kernel, seems good. Having one question, clarification would be appreciated. The screen gets pretty warm after the screen is on , say for 5 or 10 minutes and when hearing songs in background. Im coming from ninephetamine 2.1.3.
[Galaxy S II Original Android Development] gokhanmoral:
You may try another governor our use screen off profiles when listening to music in the background. Also try underclocking if you don't need 1200mhz all the time. undervolting can also decrease heart dissipation. If you are doing graphic intensive tasks when the screen is on you can also try underclocking and undervolting the GPU. Keep in mind that leaving the phone connected to a charger can make it warm.in that case you can decrease the charging current if it bothers you. See, there are lots of reasons and lots of possible solutions :)
[Galaxy S II Original Android Development] pachinkosan:
I can't see BrazillianWax in governors to choose, but savagedzen, lagfree and smartassv2 are on their places

ki3 stock, oc daemon, 1.8a6

lil question again

what's the difference between savagedzen and brazillianwax?
[Galaxy S II Original Android Development] gokhanmoral:
They are the same governor with different parameters. I will give more details about them later.
[Galaxy S II Original Android Development] jdmcivic:
@gokhan.

is the minimum cpu voltage set at 600 or 800? im hoping it is 600 and what im seeing and setting on my voltages is not some placebo effect. lol
[Galaxy S II Original Android Development] gokhanmoral:
I will check it. but you can also check if it has effect by setting 1200MHz to 800mV.

there is a hardcoded limit in the kernel I think. I did not check it yet. if that limit is 800 than it is 800...

I don't care about undervolting much in the alpha phase...
[Galaxy S II Original Android Development] tonysac:
Does lagfree, needs sleep profile in setcpu?

Also I'm still trying to find out what is the best combination of governor and settings in setcpu for totally smoothness and lagfree..any suggestions?

i have flashed 2.3.4 based rom. is it ok to flash 1.7.8 siyah kernel since it is 2.3.5 base
[Galaxy S II Original Android Development] pachinkosan:
Found some problem in 1.8a6

sometimes (dunno depends on what) wi-fi turning off waaaaaay too long

there wasn't any problem with wi-fi at 1.8a5

OP has mentioned that his kernel can be run off both 2.3.4 & 2.3.5. I am still on 2.3.4, and am running v1.8alpha6 right now. ;)

No problem here as well. On SensatioN v1.6.
[Galaxy S II Original Android Development] Tiger1335:
Hey, nice work!

But whats up with tweaking autobrightness levels?

I think its one of the most important... Display becomes never dark enough :-(

Still using your work ;-)

Thx 4 all & 1 greets

guys i want to flash the 1.7.8v. but failed. no zImage found. why? any help?
[Galaxy S II Original Android Development] gokhanmoral:
try again. it happens sometimes.

I've been flashing the kernel only with darkrom2 tool or cwm manager lately (using tar file, not zip)

does anybody know why we receive that error with CWM recovery sometimes?

is it a case-sensitivity issue?
[Galaxy S II Original Android Development] coolfire:
hey gokhanmoral, I read sometime earlier in this thread that you mentioned for Lagfree governor, screen off is operating between 100-200mhz, and with screen on, it is at min 500mhz. Does this mean that having Screen Off and In Call profiles at min & max of 200mhz, is redundant? Pardon my ignorance... :o
[Galaxy S II Original Android Development] cbeckstein:
same here on stock KI8

happens SOMETIMES but, yes, when it happens then switching takes LONG

dont flash it by CWM ... go to recovery and install it ;)

[Galaxy S II Original Android Development] lynx2k50:
Hey tonysac and grisha1.

Could you tell me details of your settings?

Pretty new to the kernel but it's really great and speedy.

Do you apply the tweaks with deamon? no frill? SetCPU?

Which are you UV settings? Do you set up an "screenoff" profile? Also with ondemand?
[Galaxy S II Original Android Development] zikarus:
Flashed a6 10 hours ago and it is running fine so far. A few observations:

Using OC Daemon with ondemand 200-1200 (wake) and conservative 100–200. Wifi off / Data on I encountered some drain with this setup last night. Leaving the phone with RAM emptied and 26% battery left it had turned out meanwhile after roundabout 9 hours of non touching.

Besides that ondemand on wake gives me a much better Quadrant performance compared to smartass (3700 vs 2700). It seems as if the GPU's fps are more stable with ondemand (on smartass they alter between 35-60+). The difference in performance was smaller on a4/5.
[Galaxy S II Original Android Development] tonysac:
Using setcpu only, 100-1200 ondemand with uv:

@gokhanmoral

There are always loads of solutions as you said, ill try to get the correct combo of settings. Between im not using any graphically intensive tasks, jus brwosing. Reading books also makes the screen warm. I never felt this with other kernel. Am i missing something?
[Galaxy S II Original Android Development] cbeckstein:
I am using the same setup for ocdaemon

one question though which I found no asnwer for in this thread:

ocdaemon does not allow to set a specific scheduler

I could of course use no-frills for that, BUT then that has to be installed along side ocdaemon

and no-frills does not allow me to NOT specify a min and max CPU frequency

sort of a catch22 situation, isn't it?

So:

if i mirror the wake frequency limits of ocdaemon in the no-frills frequency setup and set my favorite scheduler in no-frills, will this guaranty a conflict free side by side of the two tuning tools?

Or is there any other way to use ocdaemon and a scheulder configurator without calling for conflicts?

[Galaxy S II Original Android Development] AndreiLux:
I've got kind of a kernel reboot, Android still running fine and all with no problems, but I can tell because all statistics disappeared; About > Stats still shows up as 10h hour uptime since last hard reboot, but battery stats & BBS show 2 hours, when it about happened, lost 2% after this. I've already had this once on alpha4.

Other than that, great. Over night drain was 2% in 6-7 hours, Wifi on, Trillian & Skype running, AOS at 3%.
[Galaxy S II Original Android Development] 2bullish:
great, only halfway through testing a5 and now a6 any chance of a roadmap Gok on when this will go final i.e are you going a7 a8 a9 a10 ad infinitum. If so I'll wait a while as impossible to test the kernel fully before the next is released. You're a machine :)

w/system.err

Hi

I thought I'd check out this kernel - it certainly looks incredibly feature-rich.

I flashed this over a new KI8 install and I notice the following errors in logcat. lots of them. it's as though dalvik isn't working. I did wipe all the usual things after flashing both KI8 and this kernel -(1.8 alpha6).

What do you reckon? Is this an issue or something I've done?

Thank you

Chris

Restore your efs .... Your modem will be back... This is the only way... No matter how many stock roms or kernels you flash, you ll never get modem back until you restore your efs files

[Galaxy S II Original Android Development] gokhanmoral:
I can compile a custom version and name it final if it will make you feel better :)

I don't know how many versions I will release before reaching final.this version is highly experimental and I don't think I will make it beta until we have no more strange problems. I will go over the sources once again and make sure that I have not made a big mistake. Then maybe I will release another version.

Edit concerning my previous observations post: a6 does not let my SGS2 go into deep sleep mode if CpuSpy is right...
[Galaxy S II Original Android Development] :
Just a quick hi :).. Didn't sleep for over 48 hours, yesterday I flashed a5 (was a bad download I guess) and was stuck on Samsung logo first screen :D. In roaming, no computer, but had another phone with me as I always do. So I am back home, updated to ki8 & a6 and all back to normal :).

I sleep now :).
[Galaxy S II Original Android Development] pachinkosan:

at a5 everything was working fine
[Galaxy S II Original Android Development] AndreiLux:
I've had this too, delete cache partition & dalvik cache and it works again after that.

plugged in? deep sleep doesn't tend to get triggered if phone is powered by AC
[Galaxy S II Original Android Development] gusoldier:
Also no deep sleep here. Removed dalvik and cache 2 times, and reflashed once... no deep sleep...

Also there are no apps causing this, checked with betterbatterystats
[Galaxy S II Original Android Development] lynx2k50:
Wow i have to say it's the best kernel i ever used. AOS bug is complettley gone (using A6). The device is fast and responsive, running it on the default settings. The battery uis anazing, really. Never had better battery life. I didnt see any bugs yet, WiFi on/off is fast without any problems.

Can someone link me to a SetCPU guide? I want to know how to use the tool, like which frequencies to use etc. to reach a better battery life.
[Galaxy S II Original Android Development] pachinkosan:
doesn't helping
[Galaxy S II Original Android Development] gokhanmoral:
how do you check that you have no deep sleep?

if you are using cpuspy, make sure you are using back button instead of the home button to exit...

if you press home it runs in the background and shows you the same "no deep sleep" screen in the next run.
[Galaxy S II Original Android Development] Orka82:
I removed the batterycalibrated-file before going to bed yesterday. Connected to charger all night but no new file this morning..
[Galaxy S II Original Android Development] gusoldier:
Does not help. And I'm also sure it doesn't deep sleep because when I wake the phone, it wakes up right away without delay.

(also battery draining very fast).

Any other thing I can do?
[Galaxy S II Original Android Development] gokhanmoral:
you have to reboot after removing that file to start the battery calibration process which is run at the boot time...

I don't keep it running if the battery is already calibrated.
[Galaxy S II Original Android Development] crypticc:
actually forgive me pls, no deep sleep here either. a trend developing maybe or is this just CPU Spy doesn't know how to read the cpu stats any more?

Does this help at all from dmesg every entry for "sleep" has this? I don't even have BLN enabled.

yeah i'm using back button to exit

i've wiped dalvik&cache partition kinda twice already, couple of reboots etc., but the thing is that there's no deep sleep in a6 at my phone

it was at a5 and i haven't change any of programs installed

also wi-fi delay to turn off wasn't in a5, but exsist in a6 (there wasn't any troubles with wi-fi compare to others here kinda freeze or reboot when turnin wi-fi on or off in a5)
[Galaxy S II Original Android Development] ebliss:
My most choosy phone can run a6 without any problems. Deep sleep is there too. In cpu spy, try press menu, then refresh.

[Galaxy S II Original Android Development] crypticc:
Just changed to smartassv2, still none. enabling 100MHz minimum gets used, but never truly suspends.

I tell you what though, apart from this possible battery slaughterer, this kernel is the best I've tried.
[Galaxy S II Original Android Development] :
Did you guys maybe install any app update that may be preventing phone from deep sleep, due to crash I had I am running clean installation of ki8, rooted with cf kernel and then flashed straight to a6 and there is no deep sleep issue for me.
[Galaxy S II Original Android Development] zikarus:
Agreed. 1.8 is still alpha btw. If all alpha software would be as refined as this kernel there would be no need for betas and rc :-)

I have updated the first post about the changes in v1.6

now, I stop developing new features and start testing.
[Galaxy S II Original Android Development] ashagg:
No offence but I find it redundant to update the change log when 1.6 is not even available for download/test/use right now.
[Galaxy S II Original Android Development] gokhanmoral:
it's a teaser.

and plus, people may comment on new features.

for example some people may find the increase from 650mV to 750mV so disturbing and maybe they will choose to unsubscribe from this thread...

I agree, it is not so useful, but it is not so redundant either...

It will be available today, I hope.
[Galaxy S II Original Android Development] XSilentCobraX:
does anyone know if theres any problems with this kernel running on [KH3]SensatioN ROM by CRYSIS V 1.6 ?

and also is it better then speedmod T40 regarding battery life and maybe some other stuff? :)

thanks :D
[Galaxy S II Original Android Development] Остап:
I beg your pardon for a noob q. Can you explain how to use BLN and bootanimation in THIS kernel ?

Thanks
[Galaxy S II Original Android Development] gokhanmoral:
to use BLN you need "BLN Control" from the market, either free or paid version.

you can use handcent sms since stock sms doesn't support it.

for bootanimation you don't have to do anything. if your rom has a custom animation it will be used during the booting process. if not, default animation will be played.
[Galaxy S II Original Android Development] Остап:
Ok. I see.

1. What apps supports BLN ? SMS-MMS ? Calls ? Mails ?

2. How to name of bootaniation .zip ( simply i've see some variants - bootanimation.zip and sanim.zip ) && where to place it ( /system/media or /system/etc ) ?

And if it possible i suppose that be worth to place your explanation of it in the 1 post .............................
[Galaxy S II Original Android Development] gokhanmoral:
it is placed as /data/local/bootanimation.bin, /data/local/bootanimation.zip or /system/media/bootanimation.zip

the startup script searches for the given order.

generally rom developers put it to /system/media/bootanimation.zip and if you want to override it you put the one you prefer to /data/local/bootanimation.zip
[Galaxy S II Original Android Development] Остап:
Thanks !

And for good work && good stuff ( kernel ) :D
[Galaxy S II Original Android Development] malavan:
cant wait with that change log
[Galaxy S II Original Android Development] AndreiLux:
I saw the change log. Please lower the GPU lower limit voltage if you can. I'm running 267MHz at 750mV for example full stable on the GPU (Tegrak). I understand some can't run that, but there's quite a handful of us which have splendid GPUs.
[Galaxy S II Original Android Development] gokhanmoral:
I have only tested with stock settings (voltage&clock)

I removed v1.5 as well.

don't forget to leave your phones charging overnight... (at least 6 hours)

---------- Post added at 08:00 PM ---------- Previous post was at 07:59 PM ----------

in the next version, it will be lowered. I have made the change already. thanks for the info.

I would be glad if other people share their experience about clock/voltage pairs because I will prepare some CWM flashable zips to adjust frequencies.
[Galaxy S II Original Android Development] AndreiLux:
GPU wise on Tegrak like I said I was running 160/267 both on 750mV because that was the minimum setting that one could input. You might as well put 500mV as an unrealistic lower bottom so that we can slowly step up and find out what's possible and not. I'm sure as hell curious to know what mine can handle. The GPU is on another process node than the CPU so who knows.

And I have to say this: AWESOME ATTIUDE! ;) I've been waiting for a developer so motivated as you are. If you deliver on the next version, tell me where I can do a little donation :D

PS: the charging voltage might be something to consider for those who use the extended 2000mAh Samsung battery, it has ~18-19% lower resistance so it will get hotter than a stock one. I actually ordered one but the thing hasn't arrived yet. Will report on it once I have it.
