[KERNEL][3.0.Y][LINARO][OC/UV] Skull Kernel - v1.0 [18/06/2013 | FEATURES & TWEAKS]

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
• Overclock UPTO 1804 MHz & slightly undervolt
  Please be aware overclock could damage your phone!
  IF YOU DON'T NEED IT, CHANGE BACK TO DEFAULT MAX FREQUENCY AND LEAVE IT THERE
• Voltage Control (VDD Sysfs Interface)
• Optimized asynchronous I/O latency on solid state disks
• Optimized ARM RWSEM (read/write semaphore) algorithm
• Optimized kernel memory process to improve performance
• Optimized auto-scheduler
• Tuning LMK minfree value
• Battery Life eXtender (BLX)
• Dynamic dirty page writebacks (check here for more details)
• Dynamic File Sync (check here for more details)
• Frandom (fast random generator) with hard link urandom and random to frandom
• Dynamic readahead size based on device disk size
• Included tweaks on kernel/ramdisk to help with system responsiveness
• Sync with upstream arco changes, as always

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

1. Boot to recovery.
2. Mount system and data (optional as I already set these when flashing the kernel)
3. Flash the kernel now.
4. Wipe cache & dalvik cache. Fix permission also. (RECOMMEND)
5. Reboot to OS.
6. 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.

Battery life extender (BLX)

Thank you..
downloading..:good:

with this kernel and cusrom liquidsmooth = GREAT :good:

 

[bhun]

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:

 

[bhun]

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.
