[KERNEL][AOSP][ICS 4.0.3][09/12/12] Mediapad EX

---

This is my modded kernel for Mediapad. Based on latest Huawei sources

Features:

-updated to newest stable kernel base (3.0.42)
-CPU CAN be overclocked up to 1,9 Ghz , on default boots at 1,2 Ghz, use SetCPU, Sytem Tuner or similar app to set desired freq
-Overclock'd 3D GPU @ 300Mhz (6 Stages 3D GPU scaling)
-Overclock'd 2D GPU @ 266Mhz(3 Stages 2D GPU scaling)
-Boosted L2 cache (1566 Mhz max)
-Increased bus frequency - 360 Mhz from 1,5 Ghz slot upwards
-governors: ondemand (default), badass, interactive, lazy, smartass2, lagfree, conservative
-VDD interface (undervolting range between 750-1350 mv) - to set with System Tuner app from the market
-complied with Snapdragon optimized flags (-O2)
-optimized CRC32 and ARM RWSEM Algorithm
-CPU-supported unaligned accesses
-SIO scheduler(default)
-XZ Kernel Compression -> smaller kernel size
-arkusuma's touchscreen driver mod
-JHASH v3
-KSM and Automatic process group scheduling
-JRCU
-Init.d support
-Fsync control more about this feature here

Thanks to:
SebastianFM, showp1984, simone201, franciscofranco, Ezekeel, faux123, arkusuma, aftersilence and all guys how are involved in development on many different platforms



Installation:
1. Use fastboot mode to flash boot.img
2. Copy all modules to \system\lib\modules


Good lecture about governors and how to tweak them[/SIZE]

Changelog:

07.31 R00 initial version
08.01 R01 new govs: lagfree, smartass2, lazy, interactive; arkusuma's touchscreen driver mod updated (now you can customize it by yourself)
08.02 R02 undervolting fixed, LMK from kernel 3.4, 2D GPU scaling to save some juice, and other minor patches
08.04 R03 smartass tweaked a bit, new CPU OC steps (1,9 Ghz max), GPU 2D/3D OC, second core behavior fixed (it was ramping up to the max no matter what was set as max freq), recovery version thx to aftersilence!
08.07 R04 new governor: badass with two steps at 1188000 and 1512000 and tweaked for performance , fsync control, autobrightness driver: it reports now 6 levels but we need to edit framework to use those new levels
08.15 R05 updated to 3.0.40 plus some "under the hood" fixes
08.25 R06 clean start with all previous features on 3.0.41 base , i hope that i got rid of all those nasty random reboots (voltages are little bit higher on default), no CM9 support - its good enough on its own , fastboot version only (due to problems with recovery update script) , JRCU, autobrightness levels reworked once again, CAF patches
09.03 R07 cpu1 stall at 1,2 ghz fixed, CAF patches to gpu,videodecoder, hdmi, and framebuffer
09.05 R07_1 dialer reboot fixed
09.12 R08 LMK updated, kernel base updated

does it provide better battery life?

i don't now, i didn't test battery life that much

but higher cpu clocks usually means shorter battery life

Looks good. Can you add this to your kernel? http://forum.xda-developers.com/show....php?t=1792713

//ok sorry I didn't see it

it's already there:

-arkusuma's touchscreen driver mod

Already tried that! Mass improvement!!!

Thank you for the great work! Keep up that way and make MediaPad even better!

Tnx dude! Works, and looks fine!

can you explain better what do you mean for "mass improvement"?

thanks

can i specify value for last mod of "touchscreen filtering" on this kernel?

If I tried to change the VDD with system tuner, it automatically jumps to 1350mv and stuck at that voltage.
