Here's a simple kernel for AOSP based ROMS like CM9 and AOKP. Works for my tab. Can't say how it will run for you. Let me know.

v2 - Big Update. There may be bugs or issues I haven't noticed on my device.
  • Added Wheatley Governor and some associated CPUidle and C4 sleep patches to maximize effectiveness of the governor (thanks to Ezekeel)
    • allow cpu to go to sleep/deepidle while using hardware accelerated video/audio playback
    • enable powering down mpu logic during C4 / deep sleep to reduce power usage
    • Doh. Forgot to enable them when building the kernel...
  • Other misc. tweaks to Cpufreq and governors
  • Set 150mhz fuse opp to 50 OPP offset for voltage stability at lowest frequency
  • Change 150mhz slot to 180mhz to prevent SODs
  • Lower mpu vdd max to maximum value allowed by omap twl
    • Gets rid of errors and problems when using 1350mhz+
  • Removed Samsung's "Touch Boost"
    • Before, every time you touched the screen, the cpu frequency would shoot up, whether it was needed or not.
  • Removed Samsung's CPU frequency limits and locks
  • Removed touchscreen factory debug stuff and an annoying debug that was notifying you every time you touch and lifted your finger off the screen
  • Fsync off to improve file system read/write performance
  • Probably some other stuff I'm forgetting...
v1
  • MPU frequencies from 150mhz to 1350mhz
    • 150mhz slot given unique FUSE_OPP for lower SmartReflex calibrated voltages seperate from 300mhz slot
    • 1350mhz slot running at 1200mhz FUSE_OPP to keep voltages down
  • GPU overclocked to 448mhz
    • 448mhz GPU slot using same OPP as stock 307mhz slot to keep voltages down
  • Undervolted across the board
    • but really irrelevant due to SmartReflex calibrations
  • SIO scheduler
  • Lazy governor added
  • RCU priority boosting
  • Other tweaks
OnDemand or Lazy recommended

Just flashed this today and holy shit snacks! That boost to 1350 really brought my tab to life. Thank you!

I am running the V1 Kernel on my AOSP Tab 2. Is it safe to try the V2 yet??
I've been running v2 for three days now. No problems...

Yes. I've heard it even works on newer builds of aokp now.

will this work on stock rooted?
If you are rooted and on stock rom you would be so much better off just flashing tab2lite rc1 rom/kernel.It is exponentially better in every way over stock.IMO of course.If you like stock you will not be sorry flashing that rom.and I wouldn't think so since op says its for aosp/cm roms.and I don't believe its compatible with new cm9 that was recently posted.

i did try that ROM,and it was very nice,the one drawback for me was the video playback of 1080p movies.. was really choppy and out of sync.On stock they played just fine.. but i did love the Rom he put together.. and was that a yes or no to the kernal working with stock rooted ?
I am 90% sure it wont, it it may but with broken areas. This kernel is for the CM9 and AOSP code and is not meant for the stock Samsung ROM. The TouchWiz based ROM has proprietary code in it that is not 100% compatible with the open source based kernel

I would say no since it says aosp only.but I have never tried.If you look a little lower in the thread there is a stock kernel posted by dsb.Maybe you will have some luck with that.I also know metallice posted just a tab2 lite kernel only zip.I don't know if that would work either but prob a better chance of that than this.sorry I don't have a straight yes or no answer but hopefully I helped a little.

thanks for the help
I just picked up a GT P3113 yesterday, Today I flashed CWM , then CM10 and Gapps, They work great, but when I tried this V2 kernel it locked up on reboot. Any suggestions for overclocking to 1.2 - 1.3?
Thanks to all you android experts that make our tablets and phones better.

BTW I reflashed CM10 and Gapps w/wipe, working now but no kernel V2

Antutu score went from 5000 with stock rom up to 5500 with CM10

I believe CM10 is Jelly Bean based right? This kernel was one of the first developed and is made for Ice Cream Sandwich based ROMs. So it would work with CM9, but I dont think it will work right with CM10. I also dont think this kernel or the other one for the Touchwiz stuff has been in development for a very long time now

Hello everybody,
I would like to know if this kernel is also running on a GT-P3110 with stock ROM and root.
If not where can i find this kernel ?
In advance, thank you
