rc3 .. same thing.
[Galaxy S II Original Android Development] gokhanmoral:
what is the cpu time for android os process?
[Galaxy S II Original Android Development] AndreiLux:
I didn't look at it. I found that to be seemingly useless as I didn't manage to correlate that value to anything at all. You have the CPU times in BBS though, all root processes are part of AOS. I'll check next time. For now I flashed back to rc1 for a bit.
[Galaxy S II Original Android Development] gokhanmoral:
just after a boot my adroid os cpu usage is about 20secs.

this morning I rebooted the phone and just didn't use for 15-20 mins. the android os usage was about 40% but with 30-35 seconds of cpu time.

that is why I asked.
[Galaxy S II Original Android Development] inkiliuks:
Nice to follow the line, thanks
[Galaxy S II Original Android Development] terenceleechan:
gokhanmoral,

i know we're not to trust quadrant scores, but same with some others, i see fps drops down to about 20-30fps in some 3d tests (tunnel and DNA in particular) for governors excepts for ondemand. for ondemand they are normal at 50-60fps. in terms of actual usage, i see fps drops in graphically intensive games, like jelly defense (when there are a lot of alien jellies invading). it's actually noticeable. as i said again, with ondemand, there is no fps drops, but i like to try other governors without fps drops

im on sensation rom which doesn't have any tweaks, and i've tried 100mhz and 200mhz as min freq, still the same results.
[Galaxy S II Original Android Development] :
so no one flashed rc4 except me yet? :D
[Galaxy S II Original Android Development] AndreiLux:
Well I don't even care about the % anymore, but look at the CPU state times in that screenshot. Yea after boot it uses a bit but after that it should literally die and do nothing anymore.

This is the best I've ever had and was with alpha4: just see the CPU states, and this was after 6 hours not 1:
[Galaxy S II Original Android Development] dtekkt:
I'm about it :p
[Galaxy S II Original Android Development] gokhanmoral:
ok I have finished reverting drivers to update2 version drivers.

there are no drivers from AT&T sources anymore...

I have also reverted some changes I had done in rc3.

so, rc4 should be more stable... and "hopefully" this time it will be the last release candidate :)

again, if you have problems with root, flash su package.

and make sure that you clear both cache and dalvik-cache.

give the phone some time to stabilize. a second reboot is always recommended if you have problems.

I will now start to upload EVERYTHING in a tar.xz file for those who want to extract and compile the kernel. I am using ubuntu 10.04. you will just extract the file and run "./build.sh". the package will be complete. so, you can get the kernel, modify or rebrand in any way. it is not my (precious) :)

but of course I will be happy if you give credits...
[Galaxy S II Original Android Development] :
great and well done. thanks for all the efforts and work you did.

Been watching this thread for a while now, gokhanmoral I must say you are the hardest working Dev I have seen, you should be commended for your contribution.

Been running your Kernel on checkrom v5 since 1.7.8 never had an issue.

Thanks for your hard work.

[Galaxy S II Original Android Development] mcreego:
Thank You very much for your hard work. You are the best sgs2 kernel Dev.

[Galaxy S II Original Android Development] :
Please correct me if I'm wrong... Voltage control is better than set cpu for some advanced technical reasons...and sio is the best all around scheduler I should be using for balanced battery and performance?

2nd question: which governors have been tweaked by our master dev? Smartass, on demand, on demand x? The first one being battery friendly, and the last more performance friendly?

Can't wait to try 1.8 final version updated with latest sammy sources ;) this last stock Rom proved to be what the galaxy 2 should have been from the start!

Cheers
[Galaxy S II Original Android Development] AndreiLux:
That was on Cognition 1.5 (KH3) and KI3 modem. I haven't changed ROM in 2 months and if I've learned something from that is that battery life isn't affected at all by ROMs and it's all the kernel.
[Galaxy S II Original Android Development] gokhanmoral:
I have uploaded the sources and put a link in the first post.

since I have reverted some files to update2 sources there may be some additional header files and some of them may contain unnecessary information. However, it is the last version I have compiled.

I will upload the release to that link as well and I will only upload beta versions to the first post.

you will be able to download v1.6 v1.7 and sources using that link.

[Galaxy S II Original Android Development] bala_gamer:

[Galaxy S II Original Android Development] Galaxy_Fan:
Think about.

You made a backup and one day your ROM crashed. You in recovery, to the menu point restore.......and DON'T FIND your backup cause it is on the ext_sd. That's the point. If CWM 5 gives us the chance to go the right folder, then ext_sd would be a good idea but by now not.
[Galaxy S II Original Android Development] jdmcivic:
with the new recovery. seems to have broken the functionality of the CWM app. can't be used to flash files. have to go into recovery manually...

anyway with rc4. my stutters seems so be eliminated. much snappier..
[Galaxy S II Original Android Development] JHalliday0:
Just a little review on the latest versions: the best one is definitly for me a6 wich solved AOS bug for me and was deep sleep capable. Thx for this kernel
[Galaxy S II Original Android Development] :
CWM app works fine for me, reboot before flashing kernel and try again :)
[Galaxy S II Original Android Development] jdmcivic:
i have tried lots of time. did u look at the screen when it starts to boot into recovery? it shows some error and the file is not flashed. its too fast to be readable.
[Galaxy S II Original Android Development] :
flashing .tar as flash kernel or ...CWM...zip as flash update in CWM app?
[Galaxy S II Original Android Development] pepe2909:
Somebody stop the gokhanmoral:)

i joke, YOU ARE THE BEST !
[Galaxy S II Original Android Development] jdmcivic:
flashing update.
[Galaxy S II Original Android Development] :
I always flash .tar with flash kernel from CWM app.. so that's were misunderstanding is.

edit: cwm app is made to work with good old 4.0.0.2 so probably needs to be updated for new cwm, chainfire is still using 4.0.0.2 even in latest kernel releases as it is most stable
[Galaxy S II Original Android Development] HaPe1968:
Does anyone know what this "tvout resume wo" is? It can be found in BetterBatteryStats here in the sceenshots.
[Galaxy S II Original Android Development] jdmcivic:
also i noticed. when backing up via cwm app. it backs up automatically to external sd. it didnt manage to backup fully as i had like only 185mb left.

but when inside recovery mode, it backs up to Internal memory..
[Galaxy S II Original Android Development] frankcilo:
I have used v1.8rc2 this morning.....excellent for me! No freeze, great battery life, all perfect!

Now I test rc4.
[Galaxy S II Original Android Development] gokhanmoral:
good point.

I will use it as well :)
[Galaxy S II Original Android Development] AndroidGX:
Performances on rc4 seems a bit better in 3D now about smartassV2 gov.
[Galaxy S II Original Android Development] jdmcivic:
yes. rc4 is silky smooth

pls revert to the old cwm and release it already. LoL
[Galaxy S II Original Android Development] gokhanmoral:
I have just tweaked smartass2 a little bit...

compiling now...

it will be released in 10 mins... of course if nobody reports anything ;)
[Galaxy S II Original Android Development] ringrover:
is the 1.8rc4 the final ???
[Galaxy S II Original Android Development] AndroidGX:
I'am really wondering if "Voltage Control" app correctly enable UV voltages, because in this kernel my battery drains very fast (4% in 10 mins without doing anything spectatular). Already 2 battery calibrations thought. :(
[Galaxy S II Original Android Development] terenceleechan:
what did u tweak in smartass2? thanks!
[Galaxy S II Original Android Development] :
how much UV-ing are you? too much may cause higher battery drain IMHO.
[Galaxy S II Original Android Development] AndroidGX:
Really ? small values may drain much battery ? damn, didn't know that :(

Here is my values :

1200Mhz/1150mV

1000Mhz/1050mV

800Mhz/950mV

500Mhz/825mV

200Mhz/800mV

100Mhz/800mV

gov: ondemand

I/O: deadline
[Galaxy S II Original Android Development] pac213:
If you're gonna release something new, I won't flash RC4 and wait for the next release. What did you tweak in smartassv2?
[Galaxy S II Original Android Development] gokhanmoral:
no, but it is a strong candidate :)
[Galaxy S II Original Android Development] Galaxy_Fan:
Found the problem.

If you do a backup over therecovery menu everything is fine BUT if you started a backup over the cwm app the problem is there.

So from my side gokhanmoral you can built with the cwm5 :)
[Galaxy S II Original Android Development] :
well that's just my opinion it is not scientifically approved by kernel gurus :), try no UV first and see if you still get such high drain, also you need 2-3 charging cycles for your battery to be fully calibrated
[Galaxy S II Original Android Development] cbeckstein:
same her --- for all three aps:

CWM App flashing an update ZIP

DarkyROM2 flashing an update ZIP and

Romkitchen App Pro flashing mods

it is possible to have CWM app or DaryROM2 boot in to the new recovery and flash stuff manually from there but any attemp to initiate update flashes from the running app cause errors in the recovery session they trigger

as I already mentioned: this is especially bad for the Romkitchen App

tested, 100% reproducable with any rc since the invention of the new CWM 5.x.y.z

and yes: since the CWM 5.x.y.z does not allow to specify a restore pat for nandroids which points to the external SD I now have to over and over again copy nandroid backups from the external to the internal SD to be prepared for desaster... (if the backup default is external, then the restore should be it as well)
[Galaxy S II Original Android Development] Galaxy_Fan:
my values and all is fine here:

1200Mhz/1200mV

1000Mhz/1050mV

800Mhz/950mV

500Mhz/875mV

200Mhz/825mV

100Mhz/825mV

gov: ondemandx

I/O: deadline
[Galaxy S II Original Android Development] gokhanmoral:
so, this way we will be sure that any potential bug you may experience will not be fixed in the release..? :)

I made it more responsive while also making it more battery saver...

set the desired screen on freq to 500MHz again (was 200)

and min cpu load to scale up is now 70 (was 35)

since desired screen-off freq is 100, you will spend less time in higher frequencies. there will be less need for screen-off profiles even if you are listening to music.

and it will be more responsive.

we had similar values in v1.7.6 and I got very positive feedback.
[Galaxy S II Original Android Development] AndroidGX:
Ok, I will report back ater 3 more full cycles :) thanks!
[Galaxy S II Original Android Development] Molitro:
That doesn't make much sense...

With too much UV what has to happen is that the processor stops when the voltage isn't enough (so - reboot), not that it drains more to stay on...
[Galaxy S II Original Android Development] pac213:
Yeah, Start with no UV. I don't have any problems without UV maybe the hardware can't take too low voltages? I really don't know.

Scratch what I said. I just flashed it. Testing it already.
[Galaxy S II Original Android Development] Harvin Dhillon:
Just a question, will this work with the I9100G version?
[Galaxy S II Original Android Development] :
as I said that's just my opinion and me UV-ing the phones for the last.. uhm.. two years.. I really don't want to prove anything, just stating my opinion, okey?
[Galaxy S II Original Android Development] SimpleNick:
the uv range in the change log needs update, it's no longer capped at 800mV..
[Galaxy S II Original Android Development] ringrover:
thanks for answer ... im on 1.6 and its realy a fatastic work ...although with strang drain after 95% from the battery ...

100%-95% = 9_10 hours

95%-85%= only 2-4 hours here is the drain

and the same thing with Abyss2.0......

i tried Abyss 2.0 and the battery drain imadiate from 95% to 85% in in 2-3 hours ...but the first 5% it stay 8-9 hours with me ..

so i hope this strang drain after 95% was solved in 1.8
[Galaxy S II Original Android Development] gokhanmoral:
you need to calibrate your battery and give it 3-4 cycles to stabilize.

that drain is not related with the kernel.

if this is the first time you installed this kernel it is normal. you won't have the same drain 3-4 days later. but make sure that you don't wipe /data meanwhile.
[Galaxy S II Original Android Development] gokhanmoral:

Thanks! :)
[Galaxy S II Original Android Development] terente0081:
As far as I know, when UV-ing, we're not just UV-ing the CPU but the Radio too. So, when the signal is low, the Radio will struggle with less voltage to maintain signal, therefore draining more battery. UV in small steps, there's a point beyond which UV-ing hurts your battery life.
[Galaxy S II Original Android Development] :
thank you. that was my non scientific opinion also.
[Galaxy S II Original Android Development] pac213:
Still can't download 1.8.
[Galaxy S II Original Android Development] :
nothing can be downloaded from siyah xdacloud so maybe a permission error or something, hope it will be fixed soon.

I was on my way home. I will upload 1.8 to the first post in a minute.
[Galaxy S II Original Android Development] Molitro:
If it's true that the radio recieves less voltage too, then it can be.

If it's just the processor, no.

[Galaxy S II Original Android Development] gokhanmoral:

I tried touch-x and revolution roms lately and boot animation was working.
[Galaxy S II Original Android Development] pac213:
No problem :)
[Galaxy S II Original Android Development] :
as I said, I am undervolting phones for 2 years now and that is my experience, -25mv for higher frequencies, -50mV for lower .. everything else causes higher battery drain .. it doesn't matter, maybe it is just placebo. I never stated it as a fact or soemthing that is proved to be correct.

It is the same as I do all the wipes in recovery twice. probably once is enough, but all the different phones and errors have made me do it this way. also reboots, I do always 2 reboots after installing anything.

we are here to share experience. I never claimed anything I said is correct.
[Galaxy S II Original Android Development] sLapshock:
so does that mean, my checkrom v5 does not allow the boot animation to be working?

[Galaxy S II Original Android Development] tomascunill:
I flashed the 1.8 release.

Everything is going phone, the reboot was good and I'm experiencing good smooth results with ondemand.

The only weird thing that never happened to me before was an oscilation in the FPS while doing quadrant, especially in the tunnel and dna animations. The values were going down to 20 and up to 70. I don't know if this is a problem but with 1.7.8 I was getting values always between 58 and 60. I read in previous posts that this was a stability problem but I really can't say anything since I don't really understand what it means, just reporting it so you guys can interpret it.

Anyway, my experience report (based on how I feel), everything is great.
