[KERNEL][AOSP 4.4]Firekernel for yuga v0.3.1 beta

Futures:
- under voltage support
- gamma control (to use it you need to run insmod /system/lib/modules/msm_kcal_ctrl.ko or add such file in init.d:
- sound control (faux code)
- gpu oc to 450Mhz
- gpu voltage control (you can access it via /sys/devices/system/cpu/cpufreq/vdd_table/gpu_mv_table default values are 945 mV, 1050 mV, 1150 mV to change the voltage run for example
- cpuquiet for best cpu hotplug policy, I suggest to use load_stats for best balance between battery live and performance
- cpu governors (default preservative):

• preservative for best battery live without losing any smoothies in system UI and ever day usage! http://xdaforums.com/showpost.php?p=50173462&postcount=662
• inteliactive for best performance

- LoUIS cache
- kernel runs in NEON mode
- optimized ARM RWSEM algorithm
- memutils optimization
- uksm - optimized RAM usage, using only a little bit of cpu power for that
- dynamic writeback - dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off. more info http://xdaforums.com/showthread.php?p=42354290#post42354290
- interactive gpu governor
- Linaro and compile optimization -Ofast
- other small changes, to read in github commits

Big thanks goes to:
- rebelos for SlimKat (base source for this kernel)
- DooMLoRD, alnikki25k, jeroenqui, aidfarh for they kernel for yuga, often explored they repos for interesting things and changes
- faux123, ak and francisfranco for they kernel for other devices, I have taken much from they work
- And others with I not remember now!
-

FAQ:
- this kernel should run on most AOSP 4.4 based ROM's but I am testing it only on SlimKAT, report on with ROM's it works too
- for now no OC support - Z is fast enough phone, but is is getting hot on high usage and eats the battery fast so I don't think OC is really usefully
- on default settings you will got lower benchmark score in for example Antutu it got ~17k instant 20k - this is because we are using preservative cpu governor as default but since they are no lags in every day usage I don't care about it! Change to inteliactive if you want higher benchmark scores

ROM's on they it doesn't work (for now, tested by other users):
- Vanir
- DU
- Pabx
- OmniROM

Changelog:
v0.3.1
- fixed wakeup gestures - now they should work

v0.3
- gpu voltage control
- force run all cores on one freq when user sets other min/max freq
- small gpu code cleanup form xzaosp
- gamma control
- true cd-rom emulation mode
- doubletap2wake and sweep2wake via generic sysfs files
- fixed wifi speed (I had some problem to get my full network speed on wifi)

Excellent, will give it a shot on Vanir 4.4.2.

EDIT:

Doesnt work with Vanir, get past boot logo, during boot animation, it then goes into a boot loop, without the kernel logo being displayed again, screen gets lit (although still black)and just loops on and off like this,

Cheers

Does other kernels like MOEW works on it? Could you give me a logcat?

usb fastcharge is already , about s2w and dt2w in next version I think. With Gamma Control I will see what can I do.

It is beta because it wasn't tested by many users for now.

MOEW does not work with Vanir, im trying to get logcat during boot, ill also grab a syslog and upload, hopefully it helps. I managed to logcat usin adb and write output to PC, but dont know if it stopped once the device booted up with your kernel.

Will upload shortly

It looks like booth of your ROM's uses different gpu driver with isn't compatible with my, unfortunately I can not do much for now without breaking the support for CM/SlimKat and other ROM's on they it works.

No problem, i had a feeling it may have been ROM specific, any way to 'fuse' the ramdisk with the kernel similar to how alnikki25k does it, he has managed to keep compatibility by doing it this way, although there are still some graphical issues, which I think have been resolved, but not built / released since.

Either way, thanks for your work. I may have to switch ROMS, or wait for a solution.

I know what about are you talking - this needs are reworked flashable zip with generates the boot.img by using ramdisk form you old ROM with zImage (with is the kernel) when you flash it. I will provide such zip, but as you says this will not fix all problems.
