Also if you read boypes thread (maybe this is phone hardware related) you will see that switching to Google GCC 4.7 toolchain is a lot smoother for some. Don't know why (my knowledge about toolchains is limited). Maybe you could make 2 different versions based on linaro and google and see how it goes. In my case it was noticeable the performance.

And about the new feature it is doing the job (I haven't had battery drain like this since ivendor's cm10 release 1 (if I remember right) when it was 1-2% overnight). Since I flashed the new kernel (about 3 hours ago) I lost 5% in battery (using the phone) which is a lot considering the gnex lame battery life. :D

K^Kernel 3.4.51 v1.5 for JB 4.2.2

Hi guys,

I released the new v1.5 kernel builds:

- Sources synched with cm-10.1 repos of Arco68 and DevCon Team
- Built with my latest custom Linaro 4.7.4-2013.06 toolchain optimized for Cortex-A8
- Updates and fix to Interactive CPU governor (credits to Lianwei Wang, thanks to Arco68)
- dpram: Some minor changes from ics-3.0 (credits and thanks to Arco68)
- Revert Temporary workaround for flicker brightness after screen on
- Fixed flicker brightness when turning on the screen (credits and thanks to CastagnaIT)
- Fixes to display and graphic drivers (credits to Suman Tatiraju and Mayank Chopra, thanks to Arco68)
- Fixes to I/O block and ROW I/O scheduler (credits to Lee Susman and Tatyana Brokhman, thanks to Arco68)
- Fixes to ipv6 (credits to Hannes and Lorenzo Colitti, thanks to Arco68)
- Other minor fixes (from CAF sources)
- CK3 tweaks (credits and thanks to Con Kolivas)
- Increased battery check interval from 5 seconds to 15 seconds
- New static Cyanogen boot logo (credits and thanks to Stefano187)

Note:

These kernel builds are fully updated and compatible with ADC CM 10.1 Release 3.

The patch suggested by [MENTION=2905425]stuffynet[/MENTION] is not included yet and it is under test, if everything is ok, will be released with the next kernel v1.6.

Thanks to [MENTION=5041268]ktulu84[/MENTION] for his support in testing!

Thanks to [MENTION=4643755]Stefano187[/MENTION] for the new static Cyanogenmod boot logo!

Hey Christopher.

Thanks for your update ;)

Im experiencing some trouble with "Seeder" (you know that app?) and read in the official xda-thread that this might be kernel releated. Do you know the reason?

The app keeps telling me that it has no root access :(

The same problem i was getting in 4.1.2 also....
[Galaxy S Plus I9001 Android Development] Christopher83:
Seeder uses its own random redirection and has conflicts with the frandom redirection supported by my kernel and other custom kernels.

I'm sorry, but I don't want to remove a feature from the kernel to allow the Seeder execution, you may ask to Seeder team to manage the conflicts with frandom module (/dev/frandom).

I tried many kernels (different developer & different version (BIGMEM / UV / ExUV etc) most probably caused by the 3.4.48 kernel version...use stock kernel or CastagaIT kernel...but CastagnaIT kernel seems having some problem with the zip all of them are BIGMEM EXUV
[Galaxy S Plus I9001 Android Development] Diegocorta:
Instales kernel 390MB UV/OC and i have to say that its the better kernel i have tried so far.

All working perfectly, and battery seems to be aceptable...

I havent seen my phone so fast for a lot...

I have it with the baked blackbeam.

Continue with you awersome work man!

I have tried all 3.4.48 K^Kernel versions (UV, ExUV, 360MB, 370MB, 390MB) and i got few soft reboots when i boot the phone and after using phone for a few minutes it stucks and turns off... The same is with all Phenom 3.4.48 v.4.0.1 kernels.
[Galaxy S Plus I9001 Android Development] Christopher83:
Hi guys,

about the soft reboot, let me have your last_kmsg after the reboot.

You can find it inside /proc/last_kmsg

Thanks
[Galaxy S Plus I9001 Android Development] DreamerTKM:
I don't have soft reboot but just freeze when playing games like candy crush...
[Galaxy S Plus I9001 Android Development] Christopher83:
Could you try this one?

http://db.tt/FMnPJEZR

The kernel has been tested for a week, the only things I added two days ago are the squashed update to 3.4.48 and another commit by Arco from Caf sources...

K^Kernel 3.4.47 v1.1 for JB 4.2.2

Hi guys,

this kernel version should solve the reboot/shutdown issues.

[B]09/06/2013 - K^Kernel 3.4 v1.1 for JB 4.2.2[/B]
- Revert "Squashed update of kernel from 3.4.47 to 3.4.48"
- Revert "ashmem: avoid deadlock between read and mmap calls"

Let me know please...

I'll investigate on the real specific change that causes the problem...
[Galaxy S Plus I9001 Android Development] Azrael^^:
Is this the same that the one you posted before with the link to dropbox?? I have that one right now and it works like a charm. None soft reboot in this half an hour.
[Galaxy S Plus I9001 Android Development] Christopher83:
Yes, the only difference is the built date...
[Galaxy S Plus I9001 Android Development] ktulu84:
There are the 360 390 and uv version in the folder, if you want 370 exuv don't need to download again

Solved issue for me playing "Subway surfers', BIGMEM exUV.

Christopher your the best.

Have a nice day.

---------- Post added at 02:20 PM ---------- Previous post was at 01:50 PM ----------

Christopher,

I tried to configure this feature and I found out, that '/sys/class/misc/batterylifeextender/charging_limit is missing.

Only have a '/sys/class/misc/batterylifeextender', so missing subdirectory '/batterylifeextender' and charging_limit file.

You have any idea how to solve this.
[Galaxy S Plus I9001 Android Development] Christopher83:
It's strange, I have that file:
[Galaxy S Plus I9001 Android Development] JohnKersten:
I did a fresh install (factory reset) of 'Android JB [4.2.2 CyanogenMod 10.1 Devcon' and the gapps.

So maybe it's missing in this ROM or gapps.

Missing more directories.
[Galaxy S Plus I9001 Android Development] Christopher83:
Please, could you open Terminal Emulator and run these commands?

su
cat /proc/version
cd /sys/class/misc
ls -l battery*
cd batterylifeextender
ls -l

Post here the result...

Thanks
[Galaxy S Plus I9001 Android Development] JohnKersten:
Christopher,

I reinstalled gapps and fixed permissions (recovery).

After that I did the above you are asking for.

Regards
[Galaxy S Plus I9001 Android Development] DreamerTKM:
Checked....we have that file in that location...

Hi,

I have the issue in earlier version of 3.4 kernel that I lost my data of my user apps after a restart. Is that fixed ? Thanks. :)
[Galaxy S Plus I9001 Android Development] Christopher83:
Hi KingKuno,

probably it wasn't kernel related...
[Galaxy S Plus I9001 Android Development] adomm420:
Don't know if it's your KERNEL or ADC ROM itself, but my battery lifetime is definitely awesome!!! http://xdaforums.com/showpost.php?p=43135062&postcount=830

Christopher,

The first speed test with cm10.1r3 ADC and KKernel1.5 is done with 1708MHz, the second with 1401 standard. Difference is quite low.

BUT running two consecutive tests with Antutu with the same speed are resulting in different values.

I think this is down to Anturu programming. Do you recommend a better speed test? - Apart of look and feel of course ;)

Thanks for your great exUV Kernel.

[Galaxy S Plus I9001 Android Development] Christopher83:
Thank you too.

Always discard the first Antutu result, it is always the worst, a good approach consists in running at least 3 benchmark tests.
[Galaxy S Plus I9001 Android Development] ZordanKV:
I had situation with better result with 1,4GHz than 1,8GHz. :D

This Kernel has 1-2h longer running time than stock kernel of cm10.1r3 with WiFi and g2 on.

Gorgeous Christopher !

hello, I just installed this kernel K^ exUV 370MB on CM10.1 ADC (before Ivendor RC2.5 + Castagna)... all is good, but when I exit some apps and I return to Go Launcher, it redraws the icons and it spends some time, is it normal? rom fault or kernel fault?

Hi Christopher, how's progress of new apple battery saving technology implementation? I'm very curious and would be happy to be a alpha tester of this new kernel :) thanks :)
[Galaxy S Plus I9001 Android Development] ktulu84:
There are some things to check by now, Chris is working on the implementation.. We need further analysis of some results we are gathering to say if it is really useful

Apple's OSX is based on Unix (Darwin). Therefore similar base than Linux.

Amazing work with the kernel... The baterry duration is about 16 hours, from morning to night, but I have 7 hour and 20 minutes screen on.

The last time I see this was with one custom gb rom.

Best kernel ever I think.
