THIS KERNEL IS NOW OBSOLETE, DON'T USE IT.
Mine newest and stable kernel releases are now integrated into my version of CyanogenMod 7.2, please use only a kernel provided with that ROM, not this one.
Im leaving it for historical reason or for some geeks


The testing release of kernel for p350 based on kernel by drapalyuk - taken from kernel and rom + sources

I do not take any resposibility for bricked devices!

This kernel aims to optimize the performance, responsivity and battery life so please share your opinion about these factors and your ideas.

If you are experiencing any problems with WiFi or 3G try much less tweaked but more stable LITE version.

Instalation:
  • Download zip to your phone
  • Get the Custom Recovery for p350
  • Reboot into recovery
  • Backup your boot partition (if you like risk you can ommit this step )
  • Choose Flash zip menu
  • Turn off verification (as I dont signed my kernel yet)
  • Flash downloaded zip
  • Reboot and enjoy

Changelog(2.6.32.48 version):
[0.4]
  • Fixed black screen after wakeup issue
  • Added vr and sio I/O schedulers (SIO is default)
  • Added smartassv2 governor
  • VM_MAX_READAHEAD changed to 512

[0.3]
  • Kernel version updated to 2.6.32.48
  • BFS CPU Scheduler
  • Applied few tweaks from https://github.com/arco/buzz-kernel-2.6.32/
  • Some other small tweaks (List of applied patches is on github)
  • Compiled with newest Linaro toolchain with -Ofast flag and tuned to our architecture



LITE version:
For all guys having problems with internet connection on my kernel there is a LITE version.
It contains less tweaks thant normal version but should not have problems with internet. This version is much less tweaked so it should be more stable.
What is in lite version:
  • Kernel version 2.6.32.9 (not updated)
  • Smartass v2 governor
  • SIO and VR IO schedulers (SIO as default)
  • VM_MAX_READAHEAD changed to 512
  • Compiled with newest Linaro toolchain with -Ofast flag and tuned to our architecture

If you dont have any problems with 0.4 version I reccomend NOT to install Lite version


DOWNLOADS
version v0.4: http://hotfile.com/links/139705983/d...x-0-4.zip.html
version Lite: http://hotfile.com/links/139705851/5...-lite.zip.html

Thx for:
  • drapalyuk - for biggest work for this device
  • All other devs for Android kernel - as I can learn so much from all of your work!

Debuging Info
or how to help make it better

If you have any problems with my kernel and you want to help in some way - here it is some info how you can.
Just after apearing of the problem please get logs from your device.
How to do it:
  • Info on CM wiki how to get Logcat
    http://wiki.cyanogenmod.com/wiki/Logcat
  • Info about getting kmesg:
  • Open Terminal Emulator (or shell with ADB if you know how)
  • Write the following commands:
    Code:
    su
    cat /proc/kmsg > /sdcard/kmsg.log
  • There should be new file kmsg.txt on your sdcard. Copy it to your PC.
  • info about last kmsg after sudden reboot/crash
  • Same as for normal kmesg but the command now should be:
    Code:
    su
    cat /proc/last_kmsg > /sdcard/last_kmsg.txt
  • Created file will be named last_kmsg.txt
Of course if you have any programming skills you can tinker with my sources as you wish and send patches to me
