for JB 4.2.2
Since arco had switching to kernel 3.0.Y on latest CM10.1 alpha. I decide to open a new thread for my custom 3.0.Y kernel.
Hope not confuse all
Some warning to all users before flashing away!
Please do not install this kernel on any Android version lower than 4.2.Y
By flashing this kernel, you are accepting any outcome that might happen after using this kernel
I'm not responsible for any damage and your warrantly will be void!
(damage should seldom happen as I always getting this kernel tested and ONLY release it when it come stable )

with this kernel and cusrom liquidsmooth = GREAT :good:

Thanks alot !:good:
Just flashed it! My rom is Ehndroix III 4.2.2 I'll give some feedback if there sould be any problem.
I do not game, but i use my phone in various ways (everyday average use), i'll report on performance also!
Nice work mate! Keep it up! Great fan of your kernels and work.:good:

Hi there!
As i promised i'll report on performance i do now:
What's good:
1. Battery drain was only 1% during the night not in airplane mode. Awesome!
Question: increased audio loudness is missing here? I have the feeling that my phone is not as loud as with the other kernel of yours (3.4...).
Problem:
1. it just occured today, i was putting the phone in deep sleep by power button and next in an hour or so it will not answer to home button.
By (long) pressing power button the device woke up (i thought it turned of itself, but there was no pin unlock request, it just started as if it was returning from deep sleep).
Edit:
As i had Battery Doctor installed, and since then this problem occured for the first time, so i think it is related to the app not kernel.

Instructions for switching to F2FS
/!\ WARNING: This operation will wipe all your data as well as your internal storage /!\
Download an F2FS version of Pimped Kernel
Flash it in recovery
Reboot recovery, you should now be in the included modified CWM
Go to 'mounts & storage' and select 'format /data and /data/media (/sdcard)'
Go to 'mounts & storage' and select 'format /cache'
Reboot & Enjoy
Why using F2FS?
I recently compared ext4 & f2fs in a series of benchmarks, and F2FS clearly provides better performance than ext4.
You can read the full comparision & benchmark results here: http://forum.xda-developers.com/showthread.php?t=2697069
Please note that f2fs might be more prone to data corruption or otherwise be less stable, although I have not encountered any issue at the moment.

Great, flashed it. Works like last one, but still can't disable MP-decision
And can't CPU OC yet.
I don't know if Honami control will fix these issues.
Thanks, great anyway!

Subscribed. Cannot wait for this to be an awesome "pimped" kernel for CM11.
Will you have a flashable zip?
I fastboot flashed the boot.img, however no more root / superuser.
Update: flashed supersu zip - now have root.
Kernel is working fine, however getting random soft reboots every now and then.
FIOPS / 2048 readahead / Intellidemand / ECO on / intelliplug on / mpdecision off
min 300 / max 1267200 / multicore power saving 1

Thank you for your hard work, @Androguide.fr , you are making awesome things.
Testing the kernel now.
[OT Mode ON]
Also, a little bit OT, but.. does omnirom support theme chooser?
[OT Mode OFF]

Is there any possibility of including gamma control like as in Xperia Z??

Could you add pegasusq governor?

I will look into it but I don't think I'm a good enough kernel dev to do the port, if DooMLoRD ports it to DoomKernel then I will probably merge it.

If you have a link to its implementation on an other msm8974 device's kernel, please send it to me and I'll take a look.
InteractiveX2, SmartassV2 & Lagfree are merged but not enabled as they cause build errors when enabled in defconfig , I will try and fix those when I got time.
Same for the VR I/O Scheduler, it's merged but not enabled in defconfig atm.

Nice, there has been an avalanche of commits merged on the CM kernel, apparently related to the remaining camera & hardware overlays bugs, I merged those and I'm building right now.
EDIT: here's a link for the flashaholics, this one has the Omni boot logo as I'm at work and I forgot to commit the Pimped Kernel boot logo, but otherwise it's the same kernel with the new CM commits included.
I'll rebuild it tonight with the correct bootlogo and version name.

Great kernel! runs great with Omni Honami ROM (latest build) :good:

Can someone make a flashable zip of the new kernel? Iam @ work and want to flash this "on the fly"
Ty for your awesome work

@Androguide.fr there is a problem with your kernel, I get strange random reboots and sleep of death...
I tried to set governor to interactive, but no luck at all...

I won't be able to help unless you provide me with more infos such as which rom you're running and a logcat of you trying to set the governor for example.
A kmsg of the random reboots would be nice, too.
I suspect the issue is with the ramdisk as none of the above issue seem to occur on Omni.

Ok, today i will switch to aosb and then if it happens i will provide logcat an kmsg... Any app to use for that? (Apart of echo from terminal?)
Inviato dal mio Xperia Z1 utilizzando Tapatalk

Nice...wow...cool!
I am running this kernel on the new cm11 4.4.2 rom AOSB. Without problems. Now I can run my *.flac Music whith more GAIN...YEAH!
Only thing is that for example Bard´s Tale wont save the data to sd-card. Can it be solved with the kernel? I just heard in the AOSB thread its a Android 4.4 related problem. In this moment I am saving my sd-data and try to partitioning it. Or maybe this is useless? Can I get the apps to save to sd-card with this kernel maybe?

For the logcat you can use the "Catlog" app.
For the kmsg I don't think there are any apps, you'll need to use adb or the terminal:
Code:
cat /proc/kmsg > /sdcard/kernel-message.txt
or, after a random reboot to get the kmsg from before the reboot:
Code:
cat /proc/last_kmsg > /sdcard/last-kernel-message.txt

Did you have this issue with the CM kernel or the previous kernel you were running ?
If you didn't then it's probably due to the mass storage support for sdcard commits included in the ramdisk, it might not be compatible with other roms.
I will rebuild the kernel with the stock CM ramdisk tonight.

Was on stock rom before (Monx´s Rom for Z1 and DooM´s Kernel), no problem at all. Since I´ve flashed AOSB yesterday, with stock cm-kernel or this one, I have this problem.

Didn´t had success with partitioning sd-card in any way. Neither with Win7 Software or TWRP. Bad thing. Is there any patch or workaround for Android 4.4 ?

Frequently asked questions
Q: Will this conflict with any mod I'm using?
A: As long as it doesn't have any entropy related stuff, its okay. Since the kernel already comes with an inbuilt entropy generator, it will conflict with the ones from mod, causing a poor, stuttered performance!
Q: Deep Sleep isnt working for me, Google Services causing wake-locks, what to do?
A: Go to settings, Privacy, Privacy Guard, All apps, long press Google Services, and deny/disable wake-locks! (Thanks to @Paget96 for the solution)
Q: Which version should I flash
A: Flash kernel to respective model number (E612)
Q: Which frequency is the safest
A: The default frequency, 800MHz, is the safest!
But, there's no harm in overclocking upto 1100MHz.
You MAY face some issues on 1100MHz-1300MHz, but 1050MHz is stable as 'rock'!
Q: WiFi doesnt work for me
A: Reflash ROM and Kernel
Undervolt Interface:
The current voltage information is available at:
Code:
Code:
/sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
Defaults for L5:
Code:
Code:
[email protected]:/ # cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
245760: 3
320000: 4
480000: 5
600000: 6
800000: 7
900000: 7
950000: 7
1000000: 7
1050000: 7
1150000: 7
1200000: 7
1250000: 7
1300000: 7
To change for example the voltage level of the 800000 frequency, you could do:
Code:
Code:
echo '800000 6' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
If you cat this file again, you should see that the voltage level is picked up.
The new voltage level is picked up when the CPU will scale to the particular frequency level.

Long live L5!

i clean installed again cm13 with the Floppy Kernel and sometimes infinite "Rebooting Device" Screen!
Here is the logcat with ALL what happened with the phone:
http://pastebin.com/80Svhp0n
And the cpu frequency of 245-1100 causes the same effect.
Sorry for the repost.

it's a complete logcat, extracted from adb when the "rebooting device" is already displayed.
if you want I can try to cut the logcat activity in which he began to restart
PS: my phone still in "Rebooting device"

- Sound control
- KCAL Color control
- Ability to block/allow wakelocks. They are blocked by default.
- Several subsystems converted to use power efficient workqueues
- WireGuard support
- CPU Boost
- Vibration control
- lz4 as default ZRAM compressor
- ZRAM enabled by default (You can disable it)
- Ability to use fingerprint sensor as home, power and other buttons

r10:
- Oreo release, don't flash over Nougat
- Removed some useless features, check first post
- Updated to 3.10.108
r11:
- Fixed lower&higher frequencies don't show up
r12:
- Added 64 bit support, you need 64 bit TWRP to flash. Don't flash over 32 bit ROMs.
- Includes all features from R11.
- Added GPU overclock up to 600 mhz.
- Added more CPU frequencies.
r13:
- Added maple I/O scheduler, cfq is still default.
r14:
- Added ability to control wakelocks. They are blocked by default.
r15:
- Fixed remapping fingerprint as power and other buttons
- Several subsystems converted to use power efficient workqueues
- Improvements to CPU Boost/Input Boost
r16:
- Added WireGuard support
- Updated AnyKernel2
r17:
- Improved RAM management with memory leak fixes
- Set noop I/O scheduler on boot to decrease booting times a bit, cfq is still default after boot
r18:
- Reverted lastest change about setting noop I/O scheduler while booting. Confuses users because our init script in device tree doesn't set that for external. Got too many reports about it. Small hotfix.
r19:
- Added KSM, enabled by default

My usage profile for Kernel Adiutor with Frostbitten R19
These are not the best settings for performance or battery. I'm sharing to give idea. You can change anything for your usage pattern. I use social media and messaging apps.
You can find all settings in EX Kernel Manager too. I give this for Kernel Adiutor because everyone can use it, free app.

V5 works perfectly with Resurrection Remix 7/30/17 Unofficial version on AFH. Smoother than stock kernel on that specific rom.
V4 wouldn't boot with Resurrection Remix 7/30/17 Unofficial version on AFH

Does this work with 6.0 los unofficial? Or any other cm\aospcaf based rom mm?

Wow.. r5.. thank you for this great kernel keep up the good work. Keeping it updated along with du

You can use any governor mods and tweak kernel with EX Kernel Manager or Kernel Adiutor.

Please do add sweep to sleep(at least to left) because it's more comfortable than double tap the nav bar.

Working well with CarbonRom 7.1.2 latest :good:

For disabling touchboost I just have to change the value to 0?

Is there an explanation of the lazyplug profiles anywhere?
