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 )
​
Whats inside the kernel
Kernel version 3.0.82
Build with Linaro Toolchain GCC 4.7.4 2013.06 from Christopher83
O2 optimization
Default CPU governor: lulzactive
Default I/O Scheduling: ROW
A lot governors for user to choose:
interactive, conservative, lulzactive, ondemand, powersave, smartassV2, performance
More IO scheduler present in kernel also:
row, bfq, cfq, deadline, noop, sio, vr
Default max CPU frequency: 1401 MHz, Default min CPU frequence: 245 MHz

New build changelog
v1.0
[DOWNLOAD]
Included features/tweaks from my custom 3.4.Y kernel. But I also added some extra to it.
Below listed some differences:
- Tune lowmemorykiller minfree value.
- Added Dynamic dirty page writebacks.
- Added Battery Life eXtender (BLX).
- Enable Dynamic File Sync.
- Included RWSEM updates and optimizations from 3.10 kernel
- Fixed overclock 1804 MHz.
Instruction
Boot to recovery.
Mount system and data (optional as I already set these when flashing the kernel)
Flash the kernel now.
Wipe cache & dalvik cache. Fix permission also. (RECOMMEND)
Reboot to OS.
Done, enjoy.
Note: If you encounter deep sleep or force close problem after flashing my kernel, please fix permission through CWM recovery. This may help.

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.

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/P705)
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.

Thanks a lot.

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"

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.

Awesome work! I will provide the link of this topic in the topic of my rom

Update to the RC2​

E610
Just to double check:
will this work/cause any problems in E610?

Click to expand...
Click to collapse
yeeh works in e610

I got white screen freezing problems...
Flashed the original kernel again...
Using cyanogenmod 10.2
