This kernel is maded for my custom roms like CM10.2 and Mokee OS and (cooming PACMAN ) and add optimization for proper use on these roms.
Hey this thread open because several users were asking me a zip with the kernel, so I decided that would upload, the kernel for those who wish to try.
And u can try this kernel on Other roms
Tested on
OFICIAL PA 3.99
OFICIAL Cyanogenmod 10.2
and more
Features:
For android 4.3
CPU and GPU overclock
proper undervolt
Support for LZ0 and lz4 compression
Gobernators: Gaming,lulzactie,PegasusQ interactive default
I/O schedulers: deadline , v(R) ,sio, CFQ,noop optimizatios
Kexec hard boot support
better battery consumption
F2FS support
ext4 support
And more...
F2FS info
F2FS is a Filesystem so we have to Format our memory in this mode. How can we do this? We need a moded Recovery LIKE TWRP or CWM
So you need format all system , so you need backup all data, music, movies etc
How to install TWRP only extract my zip and execute script
chmod +x fastboot.sh
./fastboot.sh
Enter in the recovery TWRP
make a format data
MODDED RECOVERY:
TWRP-Multirom-F2FS suppor
[/list]
NOTE: If you change data partition to F2FS only use kernel with F2FS support, backups of TWRP normal not work on F2FS because TWRP use EXT 4, you need a moded TWRP like my version or Legolas version.
Backups of TWRP F2FS not work on TWRP normal, I made 2 versions of kernel for data EXT 4 and data format on F2FS
to restore F2Fs to Ext 4 only need flash normally TWRP and make a format Data.

from OP. "Kexec hard boot support"

Hi, testing this since yesterday and i can say all seems smoother (even at 1100). It's early to see how the battery is going with this, but if there isn't a noticiable battery drain... this will be my default kernel for cm.
Thanks.
BR.

Made me lose root on latest Rasbean. Reflashing latest SuperSU v1.51 did not fix it. Nonetheless, will test this kernel for a few days.

thnks , any issue please report

ive been using this kernel ever since the mokee rom and this update for kernel came out.its the best ive used so far. wondering though if its causing carbon rom to not charge?? on the mokee it runs perfect.

---

Same here, lost root on rasbean, and on cleanrom. Then it is no easy way to get root back, switch kernel doesnt help for me at least. I need to have root where I live, so only quick test, but kernel makes the system very fast and responsive.

ONLY NEED Download superSU form markent and install binary using TWRP or CWM option
and Root work.
