Nobody noticed that apparently samsung update2 removes problems with the yellow screen on the edges. Why do the core yellow problems, and low power consumption? yellow on the edges of annoying. especially evident when a gray background.
[Galaxy S II Original Android Development] diddsen:
could used with new ki3 too?

have somebody tried?

nice kernel
[Galaxy S II Original Android Development] Homam Ageel:
hi ma8

once i flash the kernel on stock 2.3.5

the device stock on Samsung logo !!

when i return back stock kernel it works !!!

is this has anything with bootloader or something ?
[Galaxy S II Original Android Development] RAvenGEr:
Not really sure what you are asking, but if you are having problems, the first step is to redownload and flash again with odin.

Hi Ravenger,

Just a quick update on the battery drain during charging problem I have. I have found the problem and it was not your kernel. It was a live wallpaper (Koi Live Wallpaper).

At a random time after the screen goes off, it would start using 50% cpu (I'm guessing 1 of the cores). So I guess it was going to 1.2ghz and full voltage and it was outstripping the usb 500mv supply.

The way I discovered it was with System Panel (full version) by enabling monitoring. It was there I could see the cpu time spent. It would be OK with the screen on, hence why it was so hard to track down.

All good now :) Can't wait for the update 2 version.
[Galaxy S II Original Android Development] brack11:
I love live wallpapers so much but they are really buttery suckers, so far I trade battery life for live wallpaper.

For using on ki3 what version do i download, u1, u1a or u1b?
[Galaxy S II Original Android Development] tietherope:
Whichever you wish. 1.1b will be the best.
[Galaxy S II Original Android Development] ms79723:
I just got a epic 4g touch and noticed that the battery drops to like 97% and then recharges back up to 100% and I'm aware you all know this, but if you want to change that, edit the recharge voltage in the kernel. Its in the sec_battery.c file in the source. Its currently set at 4.150V. So just bump it up to like 4.18 or 4.19V and whenever you pick up your phone off of the charger you'll either be at 99% or 100%.
[Galaxy S II Original Android Development] RAvenGEr:
Thanks for your persistance. Seems it paid off, you now know what was causing the problem. Great work.
[Galaxy S II Original Android Development] Tricky103:
Great kernel. I am using the ki3 full optimized rom from rom kitchen thread. Totally works well with this kernel

Check out screenie. Whip ass :)
[Galaxy S II Original Android Development] KennyLegend:
+1.............
[Galaxy S II Original Android Development] Tricky103:
Now on my slim rom. My mrs asked me how on earth can your phone take a picture of it's screen when the camera is on top of it... Hahaha. I dont get her sometimes
[Galaxy S II Original Android Development] tietherope:
Here is something I posted in another thread regarding battery life using this kernel:

The first day I was still at 89% after using the screen for 1 hour straight.

Right now, I admit I have been busy and have not used it as much as usual but I am at 55% after 1d 3h 13mins, with 1h 15m screen time and 40mins talk time.
[Galaxy S II Original Android Development] didopidobg:
This is simply THE BEST kernel so far! I tested nimph 2.1.3, speedmod v40, siyah 1.7.7. This kernel gives the best battery life stacked with super performance.

Just an example: I have a CPU+Temp widget (refreshed 1 sec) and I made a test:

The phone is like idle, just the screen is on, no wireless, no data, no GPS, no mobile connections, no activity at all.

Siyah 1.7.7

undervolted:

1600Mhz/1400mV |1400Mhz/1300mV |1200Mhz/1150mV | 1000Mhz/1050mV | 800Mhz/950mV | 500Mhz/875mV | 200Mhz/800mV ( i don`t mention 100mHz I don`t use it)

no setcpu or other tools

governor: ondemand (smartassv2 was even worst)

1.2ghz for 20 sec (just screen on, nothing runs in background), goes down to 200mhz, after 5 sec goes to 800mhz, again to 200 and so on. I open app drawer, scroll here and there just to raise the CPU freq. Again 1.2GHz. Stays at this for 15 sec, falls to 200, again at 800.

Quadrant: 2999 (almost like the stock SGS2)

Ragemod U1

undervolted:

1400Mhz/1250mV|1200Mhz/1150mV | 1000Mhz/1050mV | 800Mhz/950mV | 500Mhz/875mV | 200Mhz/800mV

no setcpu or other tools

governor: ondemand

200mhz, steady! Open app drawer, scroll again, open market, close it. The CPU is at 800mhz (no lag, perfect responsiveness). Drops after 2 seconds to 200mhz and stays steadily there! Just plain 200mhz.

Quadrant: 3777

So for me searching for a kernel for my SGSII finished. I stay with Ragemod.

Thanks Ravenger for your brilliant work!
[Galaxy S II Original Android Development] xinfinityoO:
lol..u just made me laugh :)
[Galaxy S II Original Android Development] kaynow:
how can you work with those values!? my phone reboots after a couple of seconds, when i set this values.

no chance to get an stable phone.

im on VillainROM 2.5 (2.3.4) with RAGE 1.1b
[Galaxy S II Original Android Development] aqualeris:
Different chips have different voltage thresholds.. Not all SGS2 can run on 800mv/200mhz. For me, it works, but it will FC very occasionally. Try raising your voltage by 25mv and test each voltage for each clockspeed.
[Galaxy S II Original Android Development] brack11:
Strange, my uv values are even smaller but phone is stable. Well, I guess the phones are different.

[Galaxy S II Original Android Development] fuze_freak:
awesome!!! battery life I can belive that my SGS2 last this long without charging thank you for this awesome kernel keep it coming
[Galaxy S II Original Android Development] tb79:
for me, ragemod is the best kernel too!

best battery life and better benchmark results @1400MHz as with other kernels @1600MHz...strange...

thx
[Galaxy S II Original Android Development] mredfern79:
I was of the same opinion until i upgraded to KI3. I am on Leomar75's revolution rom v2.7.1 KI3 using cf root kernel for KI3 v4.2.

To start on 2.7.1 i used ragemod u1 v1.1b with no OC only UV because of the battery saving. My phone would usually use 4% battery overnight.

Having really many rave reviews on the new stock cf root kernel i decided to give it a go. 1% battery drain at night and very good quadrant score. Obviously as its stock there is no OC or UV.

Sent from my Galaxy S2
[Galaxy S II Original Android Development] AndroidGX:
For me it's the contrary. Once I flashed KI3, I used CF-Root 4.2 before RAGEmod and to concluse I experienced the best battery life on RAGEmod (UVed) :

- CF-Root at night (6h30 IDLE) wifi/sync/zero apps running : 4% (96%)

- RAGEmod UVed at night same settings as above : 2% (98%)

in use (hard using) :

- CF-Root : ~10% in 15 minutes

- RAGEmod UVed : ~8% in 15 minutes

So for me it's clear, RAGEmod is one of the best kernel I've ever tested.

I'am now waiting for Ninphetamine kernel futur release optimisation for 2.3.5, and RAGEmod with Update2 source ;)
[Galaxy S II Original Android Development] nl2008:
Agreed. Ragemod kernel has amazing battery life. Great work.
[Galaxy S II Original Android Development] Priest:
Yes I experienced the same !

Right now ragemod is the best kernel, by battery and quadrant !

Thank you Ravenger !!!! :)

What do we understand by No setcpu or other tools. Are these values preset in the Kernel or do we need to use setcpu to set these values.
[Galaxy S II Original Android Development] AndroidGX:
You can always set it manually by cmd line/shell but it's much better for the mortal common to set this directly by SetCPU app (voltage tab) :cool:
[Galaxy S II Original Android Development] AndroidGX:
Latest speedmod update seems interesting :

Would be nice to see a RAGEmod 1.1c release with this :)

Many thanks !
[Galaxy S II Original Android Development] Mayday_XL:
Very good kernel, thanks.
[Galaxy S II Original Android Development] AndroidGX:
Wow ! this kernel has amazing performances so far ! never hitted any kind of those scores before with other kernels.

Take a look :cool:

All benchs @ 1400Mhz & "Performance" gov.
[Galaxy S II Original Android Development] KennyLegend:
And ur battery life and screen - on time?
[Galaxy S II Original Android Development] AndroidGX:
Didn't took the screenshot about that but anyway it was only pure benchs ;)

About battery, since I flashed RAGEmod, I finally found my KH3 battery drain back, and evenly better. I never think to take screenies about battery life but since I flashed this kernel I can make a whole day with normal/hard using (with 2.30 hours screen on) and end it at ~45%.

I'am very very happy ! :)

ps: I remarked CF-Bench is the most battery bench eater ever (2% per benchs), where on other kernels I had 3 or 4%.
[Galaxy S II Original Android Development] Galaxy_Fan:
It is by far the fastest kernel I've ever used and tested.

Look:

4499 !!! Clock on 1400GHz, undervolted 1400@1250, 1200@1150, 1000@1050, 800@950, 500@850, 200@825 and performance governor on Criskelo V18
[Galaxy S II Original Android Development] wanam:
Does this kernel support customizable charging speed?

If yes, what value must be used:

/sys/class/misc/charge_current/charge_current

or

/sys/devices/virtual/misc/charge_current/charge_current
[Galaxy S II Original Android Development] RAvenGEr:
No, does not support charging 'speed' (current) changing. I don't believe that an end user should be changing this, I have upped the charge rate for un-identifiable cables but will not change other values. Higher charging rates reduce battery life and battery service life.
[Galaxy S II Original Android Development] AndroidGX:
Hmm it seems I have some problems with this kernel, which I never had before on others, here is my 2 problems I encountered :

- random freezes (2 times), the first right during the animation of taking photo, and second right now while FTP transferring.

- freezes of the device + wakelocks (2 times) while screen off right after disconnecting from AC at 100% charge and let the device 1 hour or 2 in IDLE. (first time it was during 2 hours and battery was at 82% after turning it on again; and second time after 1 hour was 92%). Had to charge again after those bugs at 100% back.. :(

Anyone else had those kind of problems before :confused: (the second one is my major problem for me)

I precise that my UV are 100% stable (see my SIG), verified, tested and approved.

I guess that the kernel need to be optimized for 2.3.5.
[Galaxy S II Original Android Development] wanam:
It's for my Rom WanamLite, i think i'm going to remove this feature on my next update.
[Galaxy S II Original Android Development] RAvenGEr:
I would suggest that this is due to UV, it is the most likely cause of random freezes.
[Galaxy S II Original Android Development] KennyLegend:
I had similar issues without being undervolted. Phone got hot and lagged terrible.

I'm on cf root 4.2 now without issues. Maybe a coincidence I was on v1.1b.

Any chance u could have a look Ravenger ?
[Galaxy S II Original Android Development] wanam:
Many people uses this kernel on my Rom, and no similar issues for now, thanks RAvenGEr.
[Galaxy S II Original Android Development] AndroidGX:
My values are 100% stable, here is a screen of StabilityTest app with "Scaling Stability Test (Root)" mode, that I just did until now.

For information, I was at 94% when I started the test --> 24% left after 1h35 elapsed. That is 70% lost in 1h35 :(
[Galaxy S II Original Android Development] RAvenGEr:
You can't be sure that a single test correctly tests each setting, you should use the performance governor and set max to 1200, test, then set max to 1000, test, then set max to 800, test, then set max to 500, test, then use the powersave governor and test. This is the only way you can be sure all speeds and voltage settings are being thoroughly tested.

As for battery use, tests are using a lot of CPU, this behaviour is normal.
[Galaxy S II Original Android Development] RAvenGEr:
Generally this kind of issue is caused by a runaway app, i.e. one that is running in the background.
[Galaxy S II Original Android Development] Galaxy_Fan:
@Ravenger:

Saw for a few minutes that I can change the I/O scheduler on your kernel with the app Voltage control.

Do you or anyone else some experience which one is the best?

The standard scheduler is cfq, right?

What about noop or deadline?
[Galaxy S II Original Android Development] hitendra72:
i am having the same issue... replaced light.XX.so as per the link provided a few posts ago, reinstalled BLN app, rebooted the phone, but no luck :(

[Galaxy S II Original Android Development] hitendra72:
aos bug fixed?

hi

can i check whether the ragemod kernel v1.1b has the aos battery drain bug fixed?

You are talking through your hat.

I've had this discussion a few times in the last few days. The suspend0 process doesn't show up as much so it probably has contributed to fixing AOS bug.

I can get 36 hours + on Siyah kernel with wifi on all the time and over 5.5 hours screen on.

Admittedly i can get better battery life with cf root at the moment but Siyah is fairly good...as is ragemod and speedmod.

Your problem was probably a bad flash .

Every chips are different, so is accepting kernels by them.

We can't say this one if the best over this one (well for each people it's ok but we can't talk about general purpose).

To sum up : it would be useless from me to say that I tested Siyah's kernel for 3 days and I prefer to be back to RAGEmod after a huge battery drain deception from siyah's one :)

BTW, I finally get RAGEmod more stable with much less UV values (here are now my actually ones on my SIG). Since yesterday with intensive use, no more reboot, FC, freezes, better battery life, everything is perfect in KI3 2.3.5, and thus .. with the AOS bug !

Can't wait another release of RAGEmod ! :D
[Galaxy S II Original Android Development] brack11:
I wonder if there is going to be any update at observable time could someone mention at least the road which development is taking? Just out of interest.

Jeffrey promises to publish his speedfrey v4 tomorrow, and then ragemod will be the only one not updated kernel.

I'm not against of stable development and really like ragemod kernel, but this thread is so passive that it gives me some wrong ideas.

Sent from my GT-I9100
[Galaxy S II Original Android Development] RAvenGEr:
To be honest though, why 'update' a good thing?

Updates only mean something if they improve some feature or fix some bug.

I will only provide 'updates' if I believe that there is something to be gained for the end user.
[Galaxy S II Original Android Development] brack11:
Thank you, it is fair enough. But wasn't your kernel based on older stock kernel release? I guess there were some improvement in that?

Is there any point Ravenger updating his kernel new when Sammy are about to release their 2.3.5 sources??

An update post- source release would be far more beneficial.

**Sent from my iPhone 5 using Siri**
[Galaxy S II Original Android Development] AndroidGX:
Here is a list I really would like to see for a future RAGEmod release :

Kernel 2.6.35.14 based on latest samsung update source (which will be released very soon).

jhash v3

"smartassV2" governor and "ondemandX" governor

UC down to 100 Mhz

Touch screen lock frequency to 500 MHz

advanced touch tune driver support (check here)

some more battery optimizations like you said on the first post about Update2 version.

.... and you will get ... a serious WINNER kernel :D :cool:
[Galaxy S II Original Android Development] brack11:
Those are sound like syans kernel, but i agree that if ragemod would have those, and keep it's battery life or even improve it, this would be winner kernel.

Sent from my GT-I9100
[Galaxy S II Original Android Development] akira888:
To be honest, I tried Siyah's kernel for 1 day then changed back to RageMod's,

The customized governors, ondemand, stmartassv2, etc. from Siyah are just not as smooth as the stock one (I assume RageMod's is using stock governor).

They just don't feel as snappy as the stock. You feel the difference straight away after the change, frankly, it is quite obvious.:(
[Galaxy S II Original Android Development] frankcilo:
+1, finally Ragemod Kernel is the best, for now!!
[Galaxy S II Original Android Development] AndroidGX:
You are right, I'am just wondering what's so magical behind the 2.6.35.7 and Update1, which is finally better than all those higher version and more recent sources kernels.
[Galaxy S II Original Android Development] akira888:
And also siyah kernel does not have color over saturation tweak.

Overall, I don't think it is a good idea to bring over some "edges" from Siyah to Ragemod.
[Galaxy S II Original Android Development] RAvenGEr:
Actually I already have jhash 3!

Also, not sure that I need to do (or can do) anything to 'support' touch tune driver.

As for frequency lock, why??
[Galaxy S II Original Android Development] AndroidGX:
Sorry, didn't know about jhash3 ;)

For touch tune driver it for set adjust precision on touchscreen, usefull ingame (0 px), but anyway I saw you already put the value to 10px which is a good mix beween gaming and everyday use (even if I'am not a gamer, I think for these people).

And about lock frequency, I think it's was a good idea from Siyah's kernel to integrate it because it consum less power when you touch the screen, it's very usefull for people who are very often scrolling on their browser for exemple and forget to remove their fingers off the screen after scrolling; and then not only usefull for saving battery about browsing, but many other of course ! :D

[Galaxy S II Original Android Development] AndroidGX:
Update3 is out ! :)

We don't need to wait more for Update2 version I guess... :D
[Galaxy S II Original Android Development] AndreiLux:
Overclocking kernels adding additional frequency states will shift the relative state levels to a higher frequency; the touchscreen driver uses a hardcoded state level to lock to when touching the screen, and has to be lowered down to compensate. Its a simple fix. As for the Tegrak improved driver just apply the patch file which he provides O_o.
[Galaxy S II Original Android Development] RAvenGEr:
I'm not too concerned, as my Kernel has only upped this level to 800MHz. Plus this gives a more responsive feel.

Sometimes when my phone gets up from deep sleep I need to enter PIN to sim card and then unlock the phone using my symbol.

I shouldn't have been asked to enter pin, only the symbol to unlock. Pin is set to be entered only after reboot, not after each phone unlocking.

After that I can see that any connection (wifi/3g) is lost and after a second the phone is restoring connection to the internet.

The issue occurs on XXKI3 and XWKI8.

Hi Ravenger. I've also posted this in the v1-T30 thread

I have been on Siyah for quite some time and have been getting a little frustrated of late with the beta failures I've been having with it, so I just installed RAGEmod v1.1b - U1 from CheckROM Revolution kitchen. I must say I am VERY impressed. I have a few questions if that's ok:

1. What are the advantages of RAGEmod v1.1b - U1 over v1-T30, and vice versa

2. Are you any closer to your U3 release? Do you have a better idea of when this might be?

3. I've noticed on RAGEmod v1.1b - U1 it has the AOS "bug" which Siyah has fixed (or at least masked) Will U3 have this fix

4. Will it be possible to release .zip files in the future for CWM flashing as well as Odin .tar files.

5. Will you be bundling CWM 5.0.2.7 with the next release?

Many thanks, and keep up the good work
