Is there a v1.7 tar for the SC-02C? I don't see one listed on the front page.
[Galaxy S II Original Android Development] jaykhan:
Dear Friend,

Got another SOD on 1.7 rc3 and I noticed it happened when I use smartassV2 in Set CPU.

I believe smartassV2 is not working for me, never happened when was using ondemand profile.

Any idea what could be the reason?

Thanks.

im having problem in cwm recovery's backup/restore on this kernel.... when i try to backup, it backups.. but when i try to restore or advance restore it give me error "MD5 miss match" .... is this kernel bug ??
[Galaxy S II Original Android Development] eukaryote:
Investigation so far shows that it appears 100mhz might be too low for some people, as I also experience some instability at 100mhz. Bumping the min speed to 200 fixes this.

Also performance suffers according to benchmarks when using smartarsev2 compared to ondemand/interactive. This is an artifact of the way the processor ramps down to conserve battery life.
[Galaxy S II Original Android Development] beaver2233:
+1, when setting min to 100 my phone would freeze straight away, forcing to perform a hard reboot
[Galaxy S II Original Android Development] antt00:
I have done several CWM backup and restore with rc1 and rc3 (was trying out some themes). Have not encountered any problem with this function. So i think its not a kernel problem.
[Galaxy S II Original Android Development] iamsmallpang:
i agree

set ondemand !

Thanks! gokhammoral :) Great work!
[Galaxy S II Original Android Development] crypticc:
when all this work is going into the beta does it matter whether it

says

final or beta really?

p.s. b14 has logging turned on again before anyone asks before flashing.
[Galaxy S II Original Android Development] joeyfong:
Seems the battery is better than beta 13
[Galaxy S II Original Android Development] :
Working great on stock KJ1 w. b14.. Both ROM and kernel are called "smoothness" ;)
[Galaxy S II Original Android Development] minidou-77:
No one for me ?

I tried both setcpu and voltage control
[Galaxy S II Original Android Development] samsam2:
When i undervolt with setcpu in b14 i get a freeze
[Galaxy S II Original Android Development] bandit79:
u should not undervolt!
[Galaxy S II Original Android Development] rauschkugl:
But you can get similar results on sammy rom. Best for me was 7400 with beta13.

[Galaxy S II Original Android Development] droidphile:
Can somebody shed some light on a init.d script to echo last value in frequency table as 25 (replacing 100). I did search the thread and was actually confused.

Is this correct?

#!/system/bin/sh

echo "Set Frequency Table" | tee -a $LOG_FILE;

echo "1600 1400 1200 1000 800 500 200 25" > /sys/devices/system/cpu/cpu0/cpufreq/freq_table

And what should be the permissions on the file? rwx r_x r_x ? I should check UID and GID also right.
[Galaxy S II Original Android Development] samsam2:
Ok. But with 2.0 it works fine
[Galaxy S II Original Android Development] joeyfong:
Then flash back 2.0
[Galaxy S II Original Android Development] the^one123:
Hi!

B14 ondemand: fast start and deepsleep detection via low-power idle

is this only for ondemand governer or is it used by ondemandx too?

Thx

theone
[Galaxy S II Original Android Development] gokhanmoral:
thanks. I am now looking into the n7000 sources. same hardware, some newer drivers...

I will release rc1 when I have time, with n7000 drivers + some more.
[Galaxy S II Original Android Development] cokeman0:
I'm a noob to...

Created af file in the /etc/init.d folder named "CPU_Freq", containing the above, bu it's not working. no even when changing the filename to CPU_FREQ.SH, and executing the file via root explorer
[Galaxy S II Original Android Development] :
Well T-Mobile SGSII (different hardware) sources are patched up to .11 so it might be (not likely) that Samsung is aware of those issues. Anyhow update3 was released later and still .7.
[Galaxy S II Original Android Development] AndreiLux:
Heads up: The Androidmeda TWD kernel is now using the 500MHz step to enter/leave suspend state, and seemingly it's stable and haven't heard of problems with it. This will increase battery life by quite some margin due to wakelocks. Pongster said they're using a fix by arighi, but I don't know if he's talking about the the old one, or something new.

Edit: It's still the *old* 800MHz fix, he says this , this and this. If I'm not wrong, all of those are already in Siyah now. Maybe a combination of those and update3 changes make it stable.
[Galaxy S II Original Android Development] yoplaboum:
2.1b14 works fine....
[Galaxy S II Original Android Development] Ferdimage:
Can we please get the sharpness fix for Beta14 , i got used to the sharp settings on the previous kernels..

thanks
[Galaxy S II Original Android Development] :
I used it for a day or something and didn't notice increase in battery life, but it is a nice kernel nevertheless.

Regarding battery life, my point is, I don't care if my phone uses 1% or 10% over the night while sleeping, I care that I can use my phone for what I need it and spare some battery, it all depends on usage patterns and I only want that my phone lasts for a day with my usage pattern.
[Galaxy S II Original Android Development] AndreiLux:
It's not something you will notice right away without a controlled test, but fact is 1/3 to 1/2 of the awake time due to wakelocks are spent on the suspend locking frequency and a drop from 800MHz to 500MHz would decrease the theoretical power draw for that specific case by around 50%.
[Galaxy S II Original Android Development] GDT:
I'd like to try to undervolt my GPU at stock speeds and try to overclock it (giving a little fuel if needed). I need some good voltages to start from for 160Mhz, 267Mhz and 400Mhz gpu clocks. Any help?

PS: I'm using voltage control app from the market.
[Galaxy S II Original Android Development] gokhanmoral:
yes, I have both patches now. second patch is introduced in beta14 and I have been using the first patch (not the same but very similar approach) for a long time. also, I am using 800MHz locking before entering deep sleep. I tested 500mhz but it was not stable but I think it may be related with voltage levels. so I will try to use the voltage level of 800MHz with frequency of 500MHz before going into deep sleep and see what happens. this is just a feeling but I feel that it will work :) actually, the testing is easy. I remember you warned me about locking 800mhz before deep sleep even if I change the frequency table. I still did not do that and you may try to change 800MHz to 504 and see if you have any deep-sleep problems.
[Galaxy S II Original Android Development] Auridran:
The only frequency I can help you with there is 400MHz. I need the max 1200mv of voltage to be stable.

At 100Mhz I seem to be fine at the minimum voltage of 800mv. Haven't tried to undervolt any other frequency yet.
[Galaxy S II Original Android Development] :
I definitely agree. I just wanted to say that there are so many usage patterns, I have used most of the kernels and I have similar "drain" with all of them.. no UV, no downclock can do a miracle if you are using your phone. I never did any controlled tests, but I have same setup and I always get similar results, UV, OC.. maybe 10 minutes +- of battery usage with using the phone.

I still think that optimized ondemand without any profiles can produce same results like governors with sleep off profiles built in (ie. Siyah and Hardcore kernel out of the box have similar battery life and if I UV and downclock I can get like +- 10 minutes of more usage so it is just not worth it).
[Galaxy S II Original Android Development] GDT:
Which frequencies do you use for daily settings?
[Galaxy S II Original Android Development] AndreiLux:
Well TWD's still using the 500 voltage for 500, so it may just as well be stable just like that. I'll test it with the freq table changes but until now I haven't touched those since I haven't had a good reason to do it. But I'll do that in a few days since now I'm doing a battery test run (I'm 60 hours in now and battery at 66%) and want to actually get to 0% for once before I start tweaking and breaking the phone again. There's also a load of people who had already played with the freq_table and they've lowered the 800MHz (L5) state too by quite a bit (voltage too) and haven't reported any problems with it, maybe they'll be willing to test stability a bit more meanwhile.
[Galaxy S II Original Android Development] swatsbiz:
I've seen a few people here having wake up issues with this Kernel, but I've not seen any solutions. Using CM7.1, default settings for the kernel and SmartassV2 my phone keeps going to sleep and not waking up.

The last time this happened the phone wouldn't get past the boot animation (obviously corrupt something with the bad switch off)

If I'd UV'd or lowered frequency I would have accepted the problem. I assume there's a minor bug in this kernel with CM7?
[Galaxy S II Original Android Development] joeyfong:
which version & setting are u using?
[Galaxy S II Original Android Development] shrooms90:
Could someone tell me witch freqs i can modify and by wich values i can replace them? i know that i can change 100mhz-->25mhz and since a few posts back i know that i can do 800-->504, are there any others i can change? and is it possible to disable one freq step completely?
[Galaxy S II Original Android Development] hausmanis:
read the entire thread now and still didnt find an answere to this quesiton

"User customizable bus frequency selection. no more overheating. if you are a battery freak, just set it to minimum and your device will last more than ever.

Based on Update3 sources..."

How do i customize the bus frequenzy ?
[Galaxy S II Original Android Development] sunwee:
since 2.0, i've experience "No service" after boot up. But the phone will eventually find the signal after 2 or 3 (sometimes even 5) minutes. is this normal?

in the meantime the phone is fully operational - wifi etc.
[Galaxy S II Original Android Development] BoneMo:
it is not yet included in beta 14...wait for next version
[Galaxy S II Original Android Development] gsan:
can I flash this kernel into my I9100G ??
[Galaxy S II Original Android Development] gokhanmoral:
you cannot add or remove new steps.
[Galaxy S II Original Android Development] gokhanmoral:
I managed to put the device into deep-sleep @500MHz

I do it by changing the step 4 freq in PM_SUSPEND_PREPARE.

I also change step5 freq just a little to prevent having the same freq for two different steps, just to be on the safe side.

when I set 100-500 lower-upper limits with setcpu and put the phone into sleep, I do not have any higher frequency usage in cpuspy.

I think it works...
[Galaxy S II Original Android Development] smallkennwire:
Hi all ,

Please forgive this stupid question , im on siyah 2.1 b13 and my android system was 29% , android os 4% izzit normal ?

the AOS bug still running ?

Thank You
[Galaxy S II Original Android Development] hausmanis:
ah that explains why i didnt find anything, thx for the answere!
[Galaxy S II Original Android Development] gokhanmoral:
I will introduce bus frequency modification in release candidates...

I want to make sure that the kernel is stable enough.
[Galaxy S II Original Android Development] hausmanis:
Sounds logical, thx for answering, and looking forward to that feature :)

Using beta 14 atm and its super stable on low frequenzies on my phone.

keep up the super good work
[Galaxy S II Original Android Development] ebliss:
definitely stable on my phone.
[Galaxy S II Original Android Development] andyx8:
ive tried this one in MIUI but after i installed (without doing anything) i felt a slower performance on animations.
[Galaxy S II Original Android Development] AndreiLux:
The AOS bug is not a bug as it seems. New >.12 patched kernels actually hide the drain rather than fixing anything.
[Galaxy S II Original Android Development] droidphile:
Using smartassv2 governor?

Try ondemand or ondemandx and see if lag is still there.
[Galaxy S II Original Android Development] Try4Ce:
I am on 2.1b14 now, running the latest Galnet 1.10.25 with a german language pack.

This kernel performs absolutely stunning. Not only the overall smoothness is unmatched, ALL, and I mean ALL (CF-Bench, Antutu, Quadrant) Benchmarks have a significant increase in scores. And thats with stock voltage @ stock speed (1,2 Ghz ondemand).

Whats the preferred govenor anyways? the default ondemand already performs great.

Will keep an eye out for battery usage, heat production and maybe features. About to test out FM Radio and BT.
[Galaxy S II Original Android Development] bundi22:
hmm animations through touchwiz launcher and opening/closing apps is a bit choppy compared to other kernels
[Galaxy S II Original Android Development] Molitro:
Final 2.1 looks better and better by the minute.

You're doing a hell of a job.
[Galaxy S II Original Android Development] Try4Ce:
Try to experiment with the govenors. They have great impact of the animation smoothness. I did experiment on MIUI and there it was clearly visible. SmartassV2 for example has great benchmark results, but feels pretty choppy @ homescreen scrolling and animations, since it clocks pretty fast and "harsh".

ATM I use the default ondemand (not ondemandx), results in great balance between 3D/2D Speeds and animation/homescreen smoothness.

EDIT: I kinda miss the BLN feature in this kernel. BLN actually worked pretty well with the fluxi MIUI kernel. :)
[Galaxy S II Original Android Development] jonny68:
It would be good to go back to the earlier version of CWM the latest version is too buggy and doesn't work with the Kitchen Pro in CheckRom Revolution, asides from that this kernel still the best, only 3% AOS and great battery life.
[Galaxy S II Original Android Development] shr33kant:
please report back soon with BT report...I'm on CM7 and bluetooth audio is working on some players when screen off, but I'm losing headset controls after music is paused. I have to wake the screen up for it to respond to commands.
[Galaxy S II Original Android Development] m2smoe:
I like CWM 5.x, works great for me. Don't go backwards, it's pointless. If it doesn't work with KitchenPro, then KitchenPro should be updated, not the other way around.
[Galaxy S II Original Android Development] jonny68:
I don't have my data cable with me can someone make a QR code so i can scan the latest version,cheers.

---------- Post added at 11:58 AM ---------- Previous post was at 11:57 AM ----------

Kitchen Pro is constantly updated, Kitchen Pro is not where the problem lies mate it's the latest version of CWM where the problem lies, it's buggy.
[Galaxy S II Original Android Development] droidphile:
Even for me, using OTA app in GingerMod 0.6 ROM, it reboots to sammy recovery and not cwm. And about AOS usage, it's only masking the usage, and not really fixing the over-use.

I feel sorry for people who doesn't know about this kernel. They don't know what they're missing :)
[Galaxy S II Original Android Development] shr33kant:
Just download the package and flash it manually in cwm...don't be lazy :P
[Galaxy S II Original Android Development] jonny68:
how can i when i have no data cable, i would if i could:eek:
[Galaxy S II Original Android Development] m2smoe:
KitchenPro is not constantly updated, LeoMar just adds new packages to the server, there's a difference. Latest CWM has always worked just fine for me.
[Galaxy S II Original Android Development] jonny68:
i realise it's not totally solving the AOS bug but it's correctly showing it whereas other kernels did not.;)

---------- Post added at 12:06 PM ---------- Previous post was at 12:05 PM ----------

yes it is, in the last few days there have been 2 updates im now on version v1.2.3 previously it was v1.0
[Galaxy S II Original Android Development] AndreiLux:
The low usage is the *incorrect* one, you don't really have just 3% usage. There's a lot of things affecting it.
[Galaxy S II Original Android Development] jonny68:
I was under the impression after reading several comments that Siyah Kernel correctly calculated the AOS but didn't totally solve it, im a bit puzzled now as it shows as 3% and the actual CPU total is 3 mins 37 secs whereas before on standby it was anything from 15% to 70% and anything from 35 mins to 3 hours CPU??
[Galaxy S II Original Android Development] Try4Ce:
Seems to be no issue here. But was adressed once in the Galnet Forum.

After flashing this kernel, just "forget" the BT Device and pair again.

Hope that helps. Will test further later on, since I am at work right now.
[Galaxy S II Original Android Development] AndreiLux:
The CPU time doesn't matter as it all comes down to the same source, some change coming with the .12 kernel patch made it so that some processes are no longer registered to the system and thus actual usage is hidden in the statistics. This baseline value is some CPU time or something, but as it's no longer logged, you can't see it anymore. The AOS percentages are just a calculation based on these statistics, and if they're not there anymore, then of course the percentage will go down. Siyah was just the first kernel to actually implement those patches and during the first days where we were none the wiser and just saw that AOS suddenly went down and thought it was a real fix, but after more investigating, it's obvious that the whole thing is just a red herring and there are no actual benefits to it other than misleading the statistics, no matter if they were completely correct or not before (As I said, there's many other angles to this), they did show a valid correlation to drain.

Not bad for Sammy ROM (kj1) ;)
[Galaxy S II Original Android Development] shr33kant:
here's my antutu scores on cm7 nightly 94 using beta 14 @ 1600mhz on performance governor.

I mean download the package using the kitchen, then click cancel instead of installing it, then boot into recovery, goto install from zip->downloads and your files will be in there ready for you to flash ;). No data cable required.
[Galaxy S II Original Android Development] crypticc:
You may be right, but with it hidden my phone goes for 1.5 days which gets me through a day and back into work the next day if I forget to charge it. (after addressing my underlying drain which was FACEBOOK, google + and Calendar even with the sync turned off in the apps)

where as with it showing it just makes it to 24 hours so conks out on the way to work the next day.

Is there already a thread somewhere we can take up AOS discussions so we don't spam up this one with chit chat about merits of AID? Thanks
[Galaxy S II Original Android Development] sebsasko:
Why using data cable ???

Only download what you want and reboot in recovery to install downloaded kernel or package or anything you can install in CWM
[Galaxy S II Original Android Development] gsan:
can anyone help to confirm this kernel can working on I9100G? pls advise.
[Galaxy S II Original Android Development] cokeman0:
What kind of settings / Govoner / OC etc...?
[Galaxy S II Original Android Development] sebsasko:
It's perhaps because you don't have an external sd card.

CWM5.0.2.6 works fine with Leo's kitchen only if you don't have external SD.
[Galaxy S II Original Android Development] gokhanmoral:
no, it doesn't work on i9100g

Hi,

is init.d support removed/halted ?

Have tried to use Voltage Control to make an boot script, and can see the file in /etc/init.d/

But upon reboot, I does not change min/max CPU freq.
[Galaxy S II Original Android Development] BoneMo:
not sure but i think that i9000G SGSII cannot flash anything from i9100 forum..
[Galaxy S II Original Android Development] dragon546:
Gokhan excellent kernel just runs so well with latest galnet battery life and speed is just awesome.
[Galaxy S II Original Android Development] karlesg:
this is probably caused by something else (power consumption depends on way too many factors) or maybe a placebo effect.

By placebo effect I don't mean to insult you by no means. This has also happened to me sometimes. Sometimes I have the impression of something is better especially when I have seen something changed visually, but when I do a controlled test under completely controlled conditions, my "impression" is not verified.

Anyway let's wait and see the results of Entropy's controlled test about AOS drainage, so we can all have something solid to talk about.
[Galaxy S II Original Android Development] AndroidGX:
beta14 is 100% stable on my samsung rom.

And a bit better battery life from beta 13 thought ! :à

Currently trying ondemand gov, seems better in idle drain than all other olders beta (about this gov).
[Galaxy S II Original Android Development] pimser:
Have same problem. Did you realise that uv is still working with the script?!?!
[Galaxy S II Original Android Development] jonny68:
this is true.

Anyway unfortunately i will not be able to flash anymore more updates on this kernel im gonna have to stick with 2.1b until such time (if ever) that the latest CWM works fine with Kitchen Pro.

I just finished rewriting all the findings and causes of the AOS topic here. And to be honest, telling me about some random usage of yours is useless without knowing exactly what you're running in the background. I'm 65 hours in now with this charge I'm on and I have 63% battery left... so...
