[KERNEL][GPL][2.6.35.y][02/12/2012]CAF-ICS Kernel

thachtunganh · Jan 28, 2012

First, i want to say thanks to:

Fserve, Hephappy, PaoloM70, Roqu3, doixanh : For every things. All credits give to you guy, specially is Fserve, Thank you Gerson !

af974, YZ: Thanks for being good Moderators for XDA Forum

Cyanogenmod Team, Code Aurora Forum: Special Thanks for sharing their kernel source with a lot of patches! .

Tasssadar: For many advices .

DJNoxD: Big Thank for helping me and to fix errors

alezardstar, Aspee, RockR172, Andy572: Big thanks for helping me a lot

Der_Caveman, Mik_os, Franco Francisco, selphien and.... sorry i can't remember all people, Thanks for sharing and advising!

All XDA "GOOD" Members .

Bassiclly Features:

Based on "gingerbread_rel" branch from Code Aurora Forum, merged into CM7 official kernel source. Thanks to Hephappy for doing this .

Backported stuffs from 3.0 kernel to make this kernel run on ICS ROM - All Credits to LGICS Team.

Updated kernel version from 2.6.35.10 to 2.6.35.14 with Power Management patches for better battery life.

Completly Fair Scheduler with Autogroup feature.

Overclocking support. CPU Frequencies that added: from 652Mhz - 806Mhz.
- Tip: Most of P500 can overclock to 729Mhz, becareful with higher frequencies.

Implemented SmartassV2 Governor with optimizations. Use as default governor.

Implemented optimized touch screen driver with multi-touching hack and High CPU Usage bug workaround (CPU Usage goes high when you touch the screen).
- Thanks to Der_Caveman for rewriting a better touch screen driver, waleedq and sippolo for implementing Axis Inversion hack, fserve for High CPU Usage bug fixes.

Camera Flickering fix

Tons of patches/tweaks from CAF, Cyanogenmod, me, many other people... All credits to them!

Bugs:

Enabling GPS will bring "GPS wakelock". This will prevent your phone from going to deep sleep
Fix: Reboot your phone after enable GPS.

Random Rebooting... Nothing to say!

Reporting bugs:

Provide logcat when report bugs!

How to install:

Install the Kernel:

Reboot to Recovery.

Backup all thing FIRST!

Choose the caf-p500-xxxxxxxx-xxxx.zip (xxxxxxxx-xxxx is the kernel version)

Done it right? Reboot the system and Enjoy.

Tricks/Tips for getting better battery life:

Use the default governor - smartassv2! Highly Recommend!

Don't use CPU Profiles, SmartassV2 already has that.

Don't over clock your phone to higher than 729Mhz.

AngryWolf80 said:

Is it possible to enable uid_stat in this kernel?
This stuff activates per application traffic counter. Very useful thing with expensive mobile internet...

. Well, thank you for the tip
- Apply some PM patches, hope those patches can improve battery life
- Use XZ compression to compress kernel image.
- Please notice this version is for testing!

09/10/2012:
- Compiled with lastest Android NDK (r8b - new 4.6.3 GCC for ICS and Jelly Bean). And now Wifi module size is reduced from about 3MB to ~400KB .
- TUN/TAP module now is built in kernel image . Well, get more free space on ICS and Jelly Bean is awesome
- Update to Kernel release 2.6.35.14. :victory: (But i haven't apply some Power Management (PM) patches yet).
- Add Snappy compression support to zram. (this patch is from Zeev Tarantov . With Snappy, Zram uses less CPU time and is thus more useful, thanks to him!)

Have you undervolted higher frequencies or just till 748?? 0_o

No, description says undervolted low frq from 122-480

His previous version had 748 undervolted... m running it right now @748 without any random reboots which my phone used to get earlier @ that frequency...

Wait, il flash it n test...

It's also not working with Stock Cm7 kernel may be it's the problem in rom so chill

okay confirmed problem is in ROM

gurpreet9080 · Jan 28, 2012

is it a .35 kernal or .32??

Less power on device, better battery.
But lower performance I think.

And why differs this kernel from Franco, like the ICS kernel? I think we already got enough kernels

Greets!

Oh, you mean the camera exposure , it's the camera flicker right?
If it right , it is the OC method , i use SoC OC method from cyangogenmod source.
The flicker fixed long time ago, i will fix it when i release the ICS kernel

Undervolt will under the voltage of CPU Frequencies , it'll give you bettery battery life and stablity. And about the undervolt 748Mhz freq , i didn't do that.... I didn't test to undervolt 600Mhz and higher frequencies... doixanh (i took the undervolt frequencies from him) told me that it will crash when i undervolt 600Mhz and higher frequencies

santachaos · Jan 28, 2012

Undervolt just decrease stability and only increase battery life by a bit.
