Hi tr4usut,

you may use an alternative extremely undervolted setting with the init.d script you can find here:

01vdd_levels_alt_exuv

- Download the script

- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension

- Copy the new file inside /etc/init.d

- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)

- Reboot

You can find further info on the second post of this thread (look at the CPU voltage control VDD sys interface section):

Cristopher can you add fsync in you kernel are this possible ?

Because cadtaglnt has this feature an this helps to give more performamce in gaming ?

Thank you for your hard work
[Galaxy S Plus I9001 Android Development] Stefano187:
Sorry Christopher,

May I use your 1.8 kernel with ivendor's rc 2.5?
[Galaxy S Plus I9001 Android Development] ktulu84:
Yes, you can
[Galaxy S Plus I9001 Android Development] tr4usut:
Did your instruction, now your kernel working perfectly on my phone.

I think you should public script file on the OP. Change voltage and frequency to suitable and balance battery and performance is a hard and take much time work.

Thanks for your great work. :thumbup:
[Galaxy S Plus I9001 Android Development] Christopher83:
Thanks for this suggestion,

I added the Alternative Extreme Undervolted (ExUV) settings section inside the second post.

I wish you all a nice day!

Christopher i have ivendor cm10 may i use 370 kernel or 390 mb kernel?
[Galaxy S Plus I9001 Android Development] ktulu84:
it depends on what you need... if you don't need 720p video recording use 390 MB kernel. BTW they are both compatible with CM10 RC2.5
[Galaxy S Plus I9001 Android Development] tr4usut:
Waiting for kernel 3.4 :) . Kernel like 3.0 seen still laggy when playing alphalt 7 (when car run on hi-speed). Kernel 3.4 no laggy :)
[Galaxy S Plus I9001 Android Development] psaikia:
I have further reduced 50mV from the extreme UV version and tested it for around 20 days . Its working perfectly.
[Galaxy S Plus I9001 Android Development] molpie:
I installed your 1.8 /370Mb kernel on ivendor RC2.5, but, after installation, the phone don't use the deep sleep status for the CPU. I followed your installation instructions (wipe cache / wipe dalvik cache / fix permission / reboot / fix permission again), so, where is the problem ?

Thanks in advance
[Galaxy S Plus I9001 Android Development] Christopher83:
Could you post me a screenshot of your current battery stats, please?

Thanks!

It might happen if u have enabled bln... Coz bln wakes up the device... So it might happen....
[Galaxy S Plus I9001 Android Development] ktulu84:
It could be also viber or apollo
[Galaxy S Plus I9001 Android Development] molpie:
The bln was disabled and I have installed viber and apollo before the kernel upgrade and the deep sleep works very well.
[Galaxy S Plus I9001 Android Development] ktulu84:
I tested and I'm using this kernel, deep sleep works. Is some app wakelock. Post a screenshot of your battery stats, and if you can post a log with better battery stats. If is media server using too much CPU try to play a sound, deep sleep will work then, and use viber 2.3.1, the wake lock is a known issue (said by the viber team) with jb 4.1.2 and the latest version of viber that happens even on stock s3 firmware
[Galaxy S Plus I9001 Android Development] molpie:
You're right! I uninstalled Viber and deep sleep works correctly. Thanks.

[Galaxy S Plus I9001 Android Development] spaazm:
It seems I suffer from the same issue. An occasional fc of a heavy game. The longer I play it the bigger the chances.

Your script did the work. Since I installed it none fc whatsoever.

Kernel is behaving flawlessly. Since 1.7 I no longer overclock and still get a great performance. This and probably Intellidemand governor provide me the best battery life ever experienced.

Thanks for all the work you put into this kernel.

First of all thank you christopher for awesome work ,

Really good kernel

I have a question , I think its not related to this kernel so Im sry :

I couple of weeks ago I rebooted my phone will listenning to music and phone was charging after reboot phone got into bootloader.charging mod I pressed power , phone waked but there was no antenna ! Just as when in airplane mod ; IMEI said unkown and my phone was shutting down suddenly every few minutes also while in twrp it was like that ; phone some times turned off ! I tried all wipe but no success ! Finally I managed to restore System & Boot of GB so my phone returned to normal mod, IMEI returned and.....

I'm really amazed ! I do not think it was a sudden efs messed up ! Really unblievable !

Hi Christopher,

As requested some days ago, PFA my battery drain ( Very good, in my opinion)
[Galaxy S Plus I9001 Android Development] TwinHeadedEagle:
Yes, battery is great, maybe the best for 4.1.2

I have to say one more time that this kernel along with PFK Manager is exceptional :)

I have to commend Christopher for his contribution to this community because every new version is better then previous :)

how big are the lmk-changes in 3.4? i noticed that every now and then all apps are kicked out of cache even if i dont use apps which require a lot of ram. i just went down to 143mb used ram which went up to 250 a few seconds later. my ram doesnt get as full as it does with other kernels. i dont know what i should think about that. its as if a taskkiller is running on my phone.

K^Kernel 3.0.78 v1.9 for JB 4.1.2 and JB 4.2.2

Hi guys,

I released the new v1.9 kernel:

- Kernel 3.0.78
- Sources synched with jb-3.0 repos of Ivendor and Arco68 for JB-4.1.2 (CM 10) kernel builds
- Sources synched with cm-10.1_3.0 repo of Arco68 for JB 4.2.2 (CM 10.1) kernel builds
- Built with my latest custom Linaro 4.7.3-2013.04 toolchain optimized for Cortex-A8
- Removed pop-up noise at the end of power off sequence (Thanks to CastagnaIT)
- Fixed bluetooth files transfer, the issue was present only on CM 10.1, ported from 3.4 kernel branch (Thanks to Arco)
- Changes to fix the suspend problems caused by BLN

Thanks to [MENTION=5041268]ktulu84[/MENTION], [MENTION=4643755]Stefano187[/MENTION], [MENTION=4436612]TwinHeadedEagle[/MENTION], [MENTION=4453300]EB20XY[/MENTION], [MENTION=4530487]spaazm[/MENTION] for their support in testing!

Testing in progress

I've got some question concerning your changelog:

1) Which pop-up noise is mentioned - never heard about it ? :confused:

2) Has the BLN-Wakelock -issue been solved with this release ?

For now - the kernel is pretty smooth (390MB exUV) - If i got newer results i will post it later ...

THX in advance for your work and your answers

Rhonin
[Galaxy S Plus I9001 Android Development] ktulu84:
i try to answer yout questions if i can :)

1) the pop noise happens when you play a sound just before you turn off phone (e.g. when you have touch sounds enabled)

2)for the BLN-Wakelock i tested the kernel and tried BLN with BLN Control and it seems is working good
[Galaxy S Plus I9001 Android Development] Christopher83:
Hi Rhonin,

this issue occured sometimes during shutdown, expecially when using "Sound on screen lock"

Yes, I made some changes on bln and cypress-touchkey modules to prevent possible not released wakelocks which caused the deep sleep problems, you can find the commit and more details about it on my GitHub...

Thank you too! :good:

Is there somewhere listed some sample values for the autobrightness sensor? I'm using Xinstnace's beta 2 and that still contains the old values, which cause the display to be way too dark. I woiuldn't want to start to experience myself for those if someone has good values already.

Perhaps it would be a good idea to set a link on the first post behind "- New display drivers from Samsung Galaxy SII "

or even to an patch ZIP config file if possible to get a good "standard setting" for 4.1.2 (CM10 RC2.5) and 4.2.2 (CM4.2.2) ? :confused:

I installed this kernel in Broodrom JellyBean because I had a problem with phantom key presses. Along with the app for this problem. Look at my screenshot.

Everything works fine now but my battery life is not as good as with one of Broods own kernels.

I don't know if [MENTION=4354408]broodplank1337[/MENTION] made additional changes/optimizations on kernel side, however, as I can see inside the OP, it is based on my kernel sources/branch but it is a 3.0.72 kernel (the same kernel version of K^Kernel v1.5.5) while the latest K^Kernel v1.9 is 3.0.78... Between these two kernel update version, many things have been added/changed/updated.

Does this kernel support loop devices?
[Galaxy S Plus I9001 Android Development] Stefano187:
Hi all,

I know that this question should be a noob's one or maybe I'm going to ask something obvious but... I've switched to CM10.1 6.2.1 by davidteri since a couple of days and I'm using 1.9 kernel on it. All works great, but wifi hotspot is not working. Sometimes my phone activate hotspot and sometimes it stucks on activating the service. But when it can activate it, the other devices can't see the AndroidAP connection. Is there a way to let the hotspot work or is it impossible because CM10.1 by davidteri is compiled with 3.4.x kernel?

I'm sorry for asking this question here but I suppose that it is a problem kernel related because on stock kernel and BroodKernel v4(3.4.45 version) hotspot works.

Regards

Stefano
[Galaxy S Plus I9001 Android Development] DreamerTKM:
Agree with you...I tried it before...same problem and didn't work~
[Galaxy S Plus I9001 Android Development] Christopher83:
I never tried it, to be honest...

BusyBox seems to support the mount of loop devices, eg:

mount -o loop /sdcard/test-image.img /mnt/test

where /sdcard/test-image.img must be replaced with your image path, and /mnt/test is the mount point and must already exists (create it before testing).
[Galaxy S Plus I9001 Android Development] Christopher83:
I'll take a look... Thanks!
[Galaxy S Plus I9001 Android Development] Stefano187:
No, thank you for your disponibility Chris :beer:

Edit: on liquidsmooth by educk using your 1.9kernel hotspot works

(Thanks to [MENTION=5041268]ktulu84[/MENTION] for the information)
[Galaxy S Plus I9001 Android Development] DreamerTKM:
So mean that the problem is from ROM side???
[Galaxy S Plus I9001 Android Development] ktulu84:
as [MENTION=4643755]Stefano187[/MENTION] said with stock kernel and brood 3.4 kernel wifi tethering is working on that rom, maybe it's something related to 3.0 kernel on 3.4 rom, maybe stefano you could try with phenom kernel and let us know if it works or not
[Galaxy S Plus I9001 Android Development] Stefano187:
Ok, as you suggested i tryied PhenomKernel 3.8 and LiquidSmooth kernel extracted from build 4 (sorry [MENTION=4922835]educk[/MENTION] for not asking your permission for that) and in both cases wifi hotspot doesn't work. So, as I supposed from the beginning and you suggested in your post, there is a problem with 3.0.x kernels on rom based on 3.4.x kernel.

[MENTION=219148]Chris[/MENTION] I don't know if there are some changes that are needed on Rom side, kernel side or both sides to let 3.0.x kernel work on 3.4.x roms. (If you want I can try to make a logcat or similar, but you shold explain me how to do that...)

But there is something very singular that I need to say: with k^kernel sometimes is possible to activate hotspot even if connection is not shown to other devices, with the other kernel that I tryied hotspot stucks on activation (I don't know if it is a relevant information).

I'm sorry to always rise problems

After using the Kernel v1.9 OC_UC_370MB with CM10 R2.5 my phone start to leg like hell, I tried to fix permission again but it didn't help.

I discover some strange thing at settings->apps->running many of processes are going to re-start all the time. (see screenshot)

Now I installed another kernel and everthing is smooth and normal again.
[Galaxy S Plus I9001 Android Development] Christopher83:
Thank you for your feedback!

You will surely see the same processes with the other kernel too, and if you reboot the device, and in your case wipe cache and dalvik cache after installing a kernel it's normal that the lags go away...
[Galaxy S Plus I9001 Android Development] psaikia:
Thanks for the Battery fix of 3.4 kernel. Are you testing 10.1 rom as per your signature (just curious).
[Galaxy S Plus I9001 Android Development] Rhonin86:
Try greenify

To prevent starting apps again and again you should try greenify. With this little app you can hibernate the not wanted apps, so the continous restarts are stopped.

Just a suggestion

Cheers

Rhonin
[Galaxy S Plus I9001 Android Development] X-Jonte-X:
Sorry I didn’t make it clear. I used the kernel for a while and it works perfectly but after some days it starts to lag and I cleared also the caches and fix permission but it don’t help

Thanks, but I know this app greenify, but I don’t have problem with the running processes, my problem was that these processes are not correct running they tied always to restart and this possible make my phone lagging.
[Galaxy S Plus I9001 Android Development] Rhonin86:
Have you checked the LMK - Values ? And which kernel-version do you use ? SuperMem ?

Rhonin
[Galaxy S Plus I9001 Android Development] X-Jonte-X:

[Galaxy S Plus I9001 Android Development] krislibaeer:
ok long quote sorry for that but i quoted all

here look at this arco made some changes rom side because this flag is not used anymore in 3.4 kernels as he wrote

https://github.com/arco/android_device_samsung_ancora/commit/3654721b755b23abdf4185a248ae39521dff0370

but that means that this commit breaks wifi hotspot/tethering if you are using a 3.0 kernel on a 3.4 based rom

and davidteri deleted this flag too so no chance to get hotspot working with 3.0 kernel but thats not nessaccery because christopher did a great job and fixed the battery drain thanks for that :good:

and thanks for the great kernel you provide us here :good:
[Galaxy S Plus I9001 Android Development] Christopher83:
Thank you too for this clear explanation! :good:
[Galaxy S Plus I9001 Android Development] Rhonin86:
LMK = Low Memory Killer

you can check it with MinfreeManager. Maybe they are too aggressive, but afair Cristophers values are really low....

Another point to check:

What about your memory management setting in the performance menu ? Kernel Samepage Merging ? Release of free ressources ?

Maybe you can find out what the problem is - it seems to be a problem of the rams swappiness .... Have you tried a kernel with more available ram ?

Cheers

Rhonin
[Galaxy S Plus I9001 Android Development] oscarmalo:
waiting new kernel :)
[Galaxy S Plus I9001 Android Development] X-Jonte-X:
I didn't changed anythink at the memory management setting.

But I think I solved my issue. I installed the kernel with bigmen 390MB and greenify to set some of my apps to hibernation and now I have no problems any more. So I guess the problem was related to low memory and I have to many apps installed which are running in backround.

Thanks to Rhonin for you help!
