Hi everyone.
First of all my name is Francisco Franco, and I'm a kernel developer for several other devices, the LG P500, Huawei U8800 and the Google Nexus S.
Kernel wiki with useful information: http://forum.xda-dev...Ms/FrancoKernel
franco.Kernel features:
* THIS IS ONLY FOR 4.0.3 or 4.0.4. If you ask if it works on older roms I will shoot you
* Overclock up to 1344mhz
* Custom Voltage Control from Ezekeel
* Completely updated CRC32 library that is used for a lot of core functionaties of the system
* CFS scheduler tweaked for the best user experience
* Stock GPU clock - reason(http://forum.xda-dev...&postcount=4731)
* Simple IO scheduler by default
* Ext4 tweaked and patched up for performance
* I/O writeback backported from 3.2
* SLUB memory allocator as default
* USB HOST enabled
* TUN enabled
* ColorControl from Ezekeel
Command: echo "-10 0 -2" /sys/class/misc/colorcontrol/v1_offset
this is just an example, values range between -255 and 255. If you want the values to stick on reboot create an init.d script or use my app
* Custom ramdisk included with proper ext4 mounts for performance
* Kernel config stripped out from debug shit (only logcat and dmesg stayed)
* A lot more stuff that can be seen on my repo
/sys/class/misc/colorcontrol/multiplier
color multiplier triple (default = factory settings; set with 'echo "2004318071 2004318071 2004318071" > multiplier' for example; if the safety is enabled the color multipliers cannot be raised above the factory settings)
Changelog:
# Milestone 4
Changelog since Milestone 3
* Added 192Mhz slot
* Reverted all previous OMAP4 patches forked from Texas Instruments to fix most of the bugs coming from them
* Interactive governor patches from android-omap-3.0
* Screen_off_max_freq re-enabled and available here: /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_freq
* Lowmemorykiller driver updated to 3.4 version
* Fix for random mac id address for some users - from Imoseyon
* Special compiler flags to get some extra bits of performance
* Wi-Fi voltage back to stock to prevent signal issues
* Fix a crash present on stock kernel on i2c remove - patch from TI
* Remove generic_hotplug and Hotplug governor. The device shuts down cpu1 as it see fits so to prevent instabilities what so ever this function is now gone
* Fix to boosted sound when a notification was received - from Ezekeel
* Some OMAP4 patches from android-omap-3.0 for stability purposes
* Kernel 99% cleaned up from warnings that were present on stock kernel for stability purposes
* VDD_MIN voltage back to stock to prevent data loss or any other instability
* Add OMAP GAMMA interface - values range from 1.0 to 2.0 and are to be echoed to this file: /sys/devices/platform/omapdss/manager0/gamma
* Some MUSB patches from mainline kernel to improve battery life calling the correct pm_runtime functions on USB functions
* GPU clock is now 384Mhz by default because it can use the same amount of voltage and the same OPP as the 307Mhz giving us extra performance without taking a battery hit
* Other bunch of smaller patches and fixes that can be seen on my bitbucket repository
F.A.Q:
1. My device rebooted or crashed, how can I help?
A: Get me /proc/last_kmsg or logcat.
2. Battery sucks, my device is not entering deep sleep. FIX PLOX!
A: Fix it yourself, it's an app waking your device up not the kernel's problem
3. Signal is dropping since I flashed the kernel, amg u sucks!
A: The kernel has nothing to do with gsm/cmda signal. Make sure you have the latest radios
4. Do I need to wipe anything when flashing this kernel?
A: No.
5. Does this kernel has X or Y mod?
A: Learn to read, everything you need to know is in the features list, changelog or public repo.
