Okay.. Most of you people know who I am.. and if you know me you know I am not much of a kernel dev :p ... Regardless, I love AOSP but while running CM10.1, I felt I was missing some things that were more readily available for a Stock ROM.. Things such as (unofficial)Voodoo sound, Overclocking and Undervolting.. So I went ahead and forked CM's kernel and added a few needed things.


Notes:

Thie kernel is for AOSP only!

This kernel include's codeworkx's downgrade to mali r2p4 commit from CM's gerrit.. In this commit codeworkx specifically states that there is a memory leak. Now I will also say this.. This downgrade greatly improves the graphical glitches found in the android 4.2 ROMS, IE no more keyboard funkyness etc... I have yet to see this leak myself and think the trade-off is worth it. If this causes serious issues for people let me know.

Features:

Unofficial Voodoo sound driver (otherwise this has not been reviewed and approved by Supercurio)
OverClock up to 1.8 Ghz
CPU Undervolting
Downgrade to mali r2p4 which fixed graphic glitches

Thanks
Is this compatible with Stweaks for tuning issues?
Is the voodoo like sound a port of "scooby do" code?

no this is not compatable with stweaks nor is is Scoobydoo sound.. It does work with the voodoo sound app though.. I will say this again.. This has not been tested nor approved by SuperCurio so he could very well block the download from the app store which is in his right to do. Regardless I am sure he will eventually release proper support for Voodoo in the near future and when he does I will add it.

This kernel works just fine by my testing and I would like to send my thanks over to you. All I care about is speed, fidelity, and battery life and I have only noticed an increase in each of those fields. Soon I will work with you on this and push some helpful commits!

Definitely can tell a difference in speed and fluidity with this kernel. Thanks for putting this out. No problems so far with the latest Paranoid Android ROM.

Loving this kernel but unfortunately I have seen the aforementioned memory leak. First time earlier today Tasker complained of low memory. Been running Tasker for a while and never have I had it complain until I flashed kernel. Second time was later today when I noticed I only had ~200 mb of ram free and hasn't used my phone in hours. I have a widget on homescreen with system stats so it's hard to miss. Liking the OC/UC ability and voodoo though. Thanks again.

Same, running with the latest CM nightly. My performance has been great and my battery life is even a little better thanks to under-volting. Development for this phone has really started to explode in 2013, very happy with my choice to buy a note 2. Nice work on this kernel!

Pacman is 4.1.2 and this kernel is for 4.2.1 this is a newer version and will probably not work on older 4.1 ROMs ....
If you like pacman try out root box its better imo ....

Obviously I need to follow development more closely, huh? Thanks for the advice!
