[Xperia Tablet Z Original Android Development] BlackAfghan:
This is a kernel for Cyanogen Mod 12.1, which is based on the EvoMix kernel by Alx31TLse, olivieer and SuperHanss (full credits to them). It is compiled by a Linaro 4.9.3 toolchain, which was optimized for Cortex A9 CPUs (thanks to Christopher83). It has a focus on stability, performance, endurance and overclock-ability (roughly in that order).

It uses the original ramdisk of the installed kernel (thanks to osm0sis), for maximum compatibly in the long run and instant adaptability to most source changes of CM. For now, it probably

only works

with the very

latest unofficial CM12.1 built

by qsnc (http://xdaforums.com/showpost.php?p=58006383&postcount=1), due to the introduction of new sensor drivers! It should now works with other CM12.1 based ROMs, like crDroid and PAC, too. Please don't report bugs to qsnc, if you are using this kernel!

Features:

CPU: over/under-clock 1728MHz-192 MHz possible

governors: ondemand(plus), intelliactive, wheatley, ElementalX, ...

GPU: over/under-clock 487MHz-27MHz

governors: simple, performance, powersave, ondemand, conservative

File-systems: ext2/3/4, F2FS, exFAT, NTFS

Schedulers: noob, deadline, row, cfq, bfq, sio, fiops, zen, vr

intelli-plug hot-plugger and power saver (disable MPDecision first!)

Voltage Control (OC/UV)

Sound Control 3.x

poweramp controls (loudness enhancements)

screen colour tweaks

full NEON support

KSM support (Kernel Samepage Merging)

multicore power saver (recommended: enabled)

multirom compatibility

...

Performance: about 10% faster than original CM12.1-kernel with same settings, and some additional 20% speed by using maximum over-clocked frequencies (use at your own risk, every device is different!)

Configuration: Kernel Adiutor (https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor) or PerformanceControl 2.2.6 (http://xdaforums.com/devdb/project/?id=600#downloads)

Install

: just flash the attached zip with CyanogenMod Recovery, TWRP (http://xdaforums.com/xperia-tablet-...very-twrp-2-8-7-0-pollux-polluxwindy-t3187811) or CWM

Install a custom recovery first! The simple CyanogenMod Recovery, which comes with most ROMs, is pretty useless anyway..

Uninstall

: re-flash the complete ROM (just re-flashing the original kernel is not enough!)

Special thanks to Alx31TLse for his help and permission to post it!
