ONLY FOR v17.0 AND ABOVE

Gamma Control

Instructions for Gamma Control - More info

1. Download FauxKernel Enhancement from the play store
2. Adjust your desired color and gamma settings, then press the "apply color" button.
3. If you decided to change your GAMMA settings after you've already adjusted them, you will NEED to RESET by pressing the "reset gamma" button, then proceed to adjust your new gamma settings again!

ONLY FOR v16.0 AND BELOW

Intelli-thermal

v16.5 and above now uses a different method that is slightly more easier to implement

Trickster-MOD has been updated to include better control over intelli-thermal. Here are the recommended settings for a good thermal-performance balance

Click to expand...

Explanation

Frequency Throttle Limit : This is the maximum temperature after which the frequencies are throttled
Core Offline Limit : This is the maximum temperature after which the CPU cores are turned off

Frequency throttling cores : The cores which are throttled after hitting the Frequency Throttle Limit
Offline cores : The cores which are turned off after hitting the Core Offline Limit

Example -above

Frequency Throttle Limit : 85 C
Core Offline Limit : 75

Frequency throttling cores : Cores 0 & 1 are throttled when they hit the thermal limit
Offline cores : Cores 2 & 3 are switched off when they hit the thermal limit

Developer Message

Also, I would highly appreciate any donations for my contribution in helping you enjoy your device better. I am currently hoping to a buy a developer tablet, but don't have the funds for it. So, you could consider buying the following donate app "XzKernel Configurator" from the play store to keep me going

Advanced Xperia Recovery

What is Advanced Xperia Recovery?

This is a new method to boot into the recovery, bootloader or simply power off the phone. It is a modified binary of multirom.

How does it work?

During bootup, the system uses the FOTAKernel (which is useless for unlocked bootloaders). This partition contains the recovery that the user wants.

Advantages -

1 - All kernels that support the FOTA method can use a single recovery. Currently all CM/AOKP/PAC based kernels support FOTAKernel Recovery. Thus, even when you use another CM-based ROM, you can still retain the same recovery.

2 - Reboot to recovery from the ROM works perfectly without the need for any additional app or user interaction

3 - The kernel RAMDisk no longer contains the recovery, thus making it faster during kernel de-compression

How do I install it?

Just follow the instructions in the AROMA setup. Additionally, you can refer to this thread to learn more about FOTAKernel Recovery.
Thanks @championswimmer

How do I use it?

Initially, just tap on the screen when the phone boots up and the "Blue" LED comes up and the phone vibrates. While installing, you can configure whether you want to use the power-button or the volume keys or just use the touch-screen.

Remember! This is a single recovery solution as including multiple recoveries is not the aim of this project.

About CPU/GPU Voltage control

Setting custom CPU Voltages

The easiest method would be install Trickster Mod and perform the necessary changes.

Trickster Mod:

https://play.google.com/store/apps/details?id=com.bigeyes0x0.trickstermod

Setting custom GPU Voltages via sysfs(Only for v18.5 and below)

NB:
- Safe lock is present on MIN/MAX values:

#define GPU_MIN_VDD 900000
#define GPU_MAX_VDD 1200000

The default GPU voltages are:

+ [VDD_DIG_NONE] = 0,
+ [VDD_DIG_LOW] = 945000,
+ [VDD_DIG_NOMINAL] = 1050000,
+ [VDD_DIG_HIGH] = 1150000

Verify the actual settings:

cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_mv_table

945000
1050000
1150000

Adjust to desired values and verify:

echo "930000 1000000 1100000" > /sys/devices/system/cpu/cpu0/cpufreq/gpu_mv_table

About DoubleTap2Wake/Sweep2Wake

If you want to toggle DoubleTap2Wake execute this command on your phone (adb shell or directly), you can also add it to an init.d script

To disable DoubleTap2Wake

Click to expand...

To enable DoubleTap2Wake

echo "1" > /sys/android_touch/doubletap2wake

OR

Use Trickster MOD

Note: Sweep2Sleep is not supported by this kernel (atleast for now). You can only wake the device up.

You cannot flash a custom kernel on a locked bootloader, unfortunately.

the OP said it was stock kernel o.o

Nice to see a new Kernel
Is it possible to create an own Kernellogo?

Maybe he meant FOR STOCK firmware, not that it is stock kernel... it should mean something that this thread is in original android dev

spazzy1912 said:

Yes it did. But you cannot flash a custom stock kernel even for a stock firmware without unlocking your bootloader. The locked bootloader will reject my custom kernel as it is not signed by Sony.

Is this kernel have recovery cwm or twrp??

Both. Press Volume Up for CWM and Volume Down for TWRP

ILikeTheWayYouMove2 · Aug 18, 2013 at 9:44 PM

Nice to see a new stock kernel, looking forward to seeing what features you can implement on this, hopefully will be as good as cyanX

Testing..

alnikki25k · Aug 30, 2013 at 2:26 PM

If no one is interested, I might as well close this thread.

If anyone is still willing to try, I have a bunch of updates pushed to my git sources, which I will release as 2.0 only if necessary.

well I tried it out and it worked well , but I went back to Doomkernel. Not because yours wasnt good , i think doomkernel was just more frequently updated and had more features like fast charge etc . But i do love your work with cyanX roms and all.

ckyy · Aug 30, 2013 at 3:07 PM

Will try it later and report back with some feedback.

It's nice to have several alternatives (kernels) to choose from! Your kernel works fine and I've been waiting for the next release to test it again.

Keep up the good work, my friend! :good:
