[KERNEL][4.4.2][WIP][SGP311/312]UnleaZhed XTZ Kernel v0.2

[nok07635]

Hello! This is my first kernel, The UnleaZhed XTZ Kernel. I'm a noob in developing a kernel, so some bugs may be found in this kernel and I may not be able to fix them! One more important thing, this kernel uses the sources from some developers and I'm here to present my greatest thanks to everyone of them!

FLASH AT YOUR OWN RISK!!​

UnleaZhed XTZ Kernel

Requirements:
4.4.2 Xperia Tablet Z Wi-Fi version (SGP311/312)
Unlocked bootloader
Fastboot driver installed computer

Features:

CPU overclock up to 1836MHz
CPU UV by 100 default
CPU UV control
GPU overclock up to 450MHz (due to some bandwidth problem)
Use auto CPU hotplug instead of MP-Decision
Some minor things
!!recovery has resolution problem ATM!!

Installation:
1. Make your Tablet Z in fastboot mode
2. On your computer, open cmd and navigate to the location of kernel
3. Type "fastboot flash boot Kernel_name.img
4. Type "fastboot reboot"
5. Enjoy!

Nice try but do you have any plans for an aosp kernel?i like overclock and the extra features but it is too tough to say goodbye to pac rom

Will do but it may be done in the next month, Thanks for your suggestion.

First of all THANK YOU for spending your time on this and sharing your result with us!

Just flashed the kernel! Good news...nothing is bricked
CPU Spy Plus indeed shows 1836 Mhz used! I did´t do anything for that.
You might re-think this. Using 1512Mhz instead by default and let the users choose that high speed CPU mode themselves as it may not be stable on all devices.
That 324Mhz added is a huge step...there is no step in between possible?
What about voltages. Did you modify anything? Is the voltage raised to achieve the high cpu frequency? Please post some more information about what happens here...


In fact I´m just running Antutu to see general stability on my device.
VERY BAD score. Before your kenel there were 20300 points. Now with OC only 19746.

=====================================================================

EDIT: Just recognized.... several questions are being answered by Antutu CPU Master.
1512 IS USED by default!
1620Mhz and 1728 Mhz are there to choose and of course finally the 1836Mhz.
Scaling is interactive by default (changed to my fav ondemand)
I/O Scheduler is cfq by default (changed to my fav noop)

Antutu Score @ 1836Mhz: 16077Mhz ???
Lower than without OC? Needs retesting (14230 point when setting max to 1836Mhz and Min to 1512Mhz(!!!???)...maybe the benchmark is wrong...Will give it some time to see if I myself feel a speedup.
After Restart Antutu Score ends up @ 19761 points...not bad. but clearyl not enough looking at the massice OC done. REBOOT! Tab just rebooted! So 1836Mhz is not stable at mine! Trying 1728Mhz now instead.
18139 points....this kernel lacks some serious power if we can believe the scores of antutu. This is a V0.1 so nothing to worry too soon. You´ll make it find it´s power
Switched back to kernel from pulser_g2 (http://forum.xda-developers.com/showthread.php?t=2444452) and 19908 points without any OC! You may look into it.

But please answer the other questiones I wasn´t able to clear myself.

Greetings
Rodger

Sorry for my late,
I've tested Antutu with 1512MHz and 1836MHz. For my Tablet Z, I got ~20000 (1512MHz) and ~23000 (1836MHz).
My Tablet Z has fast binning CPU. Can you please tell me which binning your CPU is? Thank you!

 

[DJ-Tumor]

hard to tell...did taht thing in Terminal emulator....it tells me "1".

Not fast or slow or anything...

How is the battery life?

How is the battery life?

Sent from my SGP311 using XDA Premium 4 mobile app

Don´t know....after the disastrous performance of the first release I of course switched back to stock.

Now there is the new version which does not cut performance in stock mode.
I´ll OC now to 1728 Mhz and see how it performs with that....battery life is not really good with stock so if you are already asking...FORGET ABOUT alternative kernels not optimized for battery.
That is why I don´t use CM oder AOKP on my Note1. I just eats the battery for breakfast....

OK OC just seemed to scale...20300 points (ca. 19300 at stock speed)...trying 1836 Mhz now.
17389 points....clear drawback....possibly because my device seems to have a bad CPU from what I´ve learned....wanted to use the 17xx Mhz anyway....oops....device just rebooted....my device just isn´t capable of the max cpu setting. :crying:


Anyway the working 1728 Mhz working is great news!

Will give it further testing...

I have two APQ8064 devices, Nexus 4 and Tablet Z. Nexus 4 is 0 (slow), it will reboot sometimes even on [email protected], the Antutu would force close and red light of death would happen if you ignore it and attempt to run again. While my Tablet Z is 2 (fast), this can run at [email protected] and got 23XXX in Antutu.
I don't have an idea which frequency can the 1 (nominal) APQ8064 clock at, but I think [email protected] will be OK. Also, keep eyes on the CPU float-point section in Antutu. At 1512Mhz, it is around 2000. At 1836MHz, it is around 2200. If this drop lower, just pull up the voltage BUT NOT TOO MUCH!!!

Raising voltage is not an option to me. But anyway...which app do you use for that on tablet Z?
What App do you use for cou control?

I use No-frills. Do you change "interactive" and or "cfq"?

Numbers right after reboot and stopping some unused apps...just stock apps running...
2729 / 930 / 1112 / 1050 / 511 / 927 / 1436 / 5278 / 696 / 600
>>> 15269 points @ stock !!!
switching back to stock....

I would like to know this as well. Also, how do you check to see which processor you have? (0,1,2; slow, nominal, fast)

What is the terminal command to find out? I also considered custom retelling to add some processing oomph. On a per app basis, but reading this... Stock SGP311 on 4.2.2 is chugging fine just north of 20000 points on Antutu. Can we compare Versions? Mine is 3.3.1. I faintly recall reading they mixed up some benchmarking internals because some corporations found loopholes to cheat / inflate scores on new to market devices, maybe that's the discrepancy there?

Another wild thought, could there maybe be, aside from different CPU Models, different kinds of cache / memory scattered through the devices? Would not be the first time a sub par. Cache/Memory bottleneck severely strangled a nominally and factually quicker CPU into much lower overall results. Much depends on weighting within Antutu

Man, what happened with your kernel? We need some stock kernels for 4.3
