hi i will soon be discontinuing support and closing down my (DooMKernel) threads for the following devices:
Xperia Ray
Xperia Mini
Xperia Mini Pro
Xperia Neo
RIGHT NOW I AM CLOSING DOWN THIS THREAD
since i only have the Xperia ARC with me, its becoming difficult for me to manage so many devices, especially since CM7 kernel will require different kernel sources (even MiUI), the task is going to get tougher for me... also I am getting busy with some personal work so wont be able to dedicate a lot of time for the devices which i dont even have...
i have asked the Xperia Play users to think abt donating a device to me...
if they want then they can do so, then i will continue work on PLAY too... but if they are not willing, then even that kernel will be closed down...
currently hartej has Xperia Ray and will be working on the kernel for that device (i will help him get started and working )...
another thing, my dear friend Napstar is an awesome dev, he is currently working on Ideos X6 kernel/recovery/other stuff, i keep helping him out when ever he needs help ... he is willing to help me out but we will need that device with us to continue work... so if for any of the above devices you guys are willing to donate a device to him/us, i am sure he/we will continue work on kernel and much much more
i invite advanced users who have knowledge abt compiling kernels to contact me... i can help them out to keep the kernels up for that device...
for technical queries u can always send p.m. to me
hope u guys understand this...
regards,
DooMLoRD
---------------------------
hello guys!
i am new to kernel development but i think this kernel would be useful for a lot of ppl using stock SE 4.0.A.2.368 FW...
I DONT HAVE THE DEVICE SO NEED SOMEONE TO TEST IT!

[ additional info ]
ok time for some gyan!
see each cpu/chip is different
each is unique and has different tolerances
slowly keep increasing the frequency
check its stability for 5-10 hrs
check for random reboots
check which one is best suitable for ur device
if u start getting reboots/freezes then throttle back and use lower frequencies
remember just because someone elses device was able to work at that frequency/voltage doesnt mean that ur phone can support/handle that frequency/voltage
i would recommend that u DO NOT use high frequencies for long time! this may damage ur device!
[*]the high frequencies are just for temporary boost/benchmarks/showoff
[*]you have been warned!
[ how to install ]
download the boot.img
save the boot.img in the folder with fastboot binaries (fastboot.exe files)
power down device
start device in fastboot mode
use the following command to flash the boot.img
Code:
fastboot flash boot boot.img
reboot phone and enjoy the kernel
FOR OVERCLOCKING
start SetCPU/NoFrills CPU Control app on ur Mini (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

NON DEV ISSUES AND QUESTIONS ABOUT KERNEL POST HERE. THIS IS A WORK IN PROGRESS THREAD
HISTORY
I have been given Permission by the Kernel's Author (Gokhanmoral) to create this thread. Please put your issues or questions you have with the Kernel in this thread. Also functional request should also be made here. The aim of this thread is to filter out excess questions regarding the use and experience from the development thread. The author of the kernel and many experience users\testers and primary dev contributors need to use the Development thread in order to help Gokhan to implement his kernel. Would also request the community to contribute in terms of info to compile a knowledge base if you will. Many Thanks Gokhan and future contributors.

FAQ (WIP)
General
Q: Does this kernel support latest i9100 ROM which is based on android 2.3.5 -2.3.7?
A: Yes, it does.
Q: Can I use this kernel on I9100G?
A: No, you cannot. Only International i9100 and Canadian (Bell Mobility) models are supported (Chinese or AT&T T-Mobile US are not supported). Also, I compile ntt-docomo version for each release but beta versions do not support gps and digital tv on ntt-docomo devices.
Q: Does this kernel support CM7 or any other AOSP based roms?
A: Yes, but it only support CM7 or MIUI based roms for now from 2.0 and above. If you are using another AOSP based Rom tell me and I will support it.
Q. What is the latest version of the Kernel?
2.6.3 is the latest and can be found here:
SiyahKernel Edition v2.6.12 (Please ensure you choose the right one for your phone)
Q. I have an International i9100 can I flash NTT version?
A. Important Notice: the one with "ntt" in the filename is NTT DoCoMo SC-02C version. do not flash it if you have EU version
Q. Where can I get the latest Kernel Source for this Kernel?
A. It can be Found Here: Kernel Source
Q.Are there any Variants based on this Kernel?
A. Yes there is DK SIYAH KERNEL
Q: Can I use app protectors with this kernel?
A: Yes, you can. But you have to flash EnableLogger.zip using CWM after flashing the kernel.
TO ENABLE ANDROID LOGGER USE THIS:
ENABLE LOGGER
TO DISABLE ANDROID LOGGER USE THIS:
DISABLE LOGGER IF IT IS INSTALLED
Battery & Performance Factors
Q: What is battery life like on this kernel?
A: Some have said the battery life has improved. Others said not as good as others, this however maybe down to rogue apps creating wakelocks. Could be the rom is does not take advantage of the kernels features or could be a bad battery. Let's just say your Mileage may vary...
Q. I keep hearing about AOS having a factor on performance, whats all this about?
A. The Android OS using quite a lot of resources. AndreiLux wrote and in depth reference post about this which you can find here: [REF][Rewrite 26/10] What the Android OS usage is and what it's not
Q: What can I do to improve battery life?
A: put your phone into airplane mode or do not use packet data when you are not using it. Check for Rogue Apps and also check for unnecessary wakelocks and close them.
Q: I get random reboots or freezes. What should I do?
A: Make sure you boot in Recovery wipe cache and dalvik, then reflash the kernel. Although the kernel will do this if you apply the CWM.zip of the Kernel. It can still leave data behind.
If you are undervolting revert back to stock values. Then start reducing voltage by.25 and test. If that does not work make a note of:
1. When did it happen?
2. Which rom are you using, can you reproduce it
3. do you have any custom init scripts which changes kernel parameters such as freq voltage or anything else?
Post in this thread and we will try and help you.
Q: My phone doesn't go into deep sleep. What is wrong?
A: Make sure that you have cleared cache and dalvik-cache after you install the kernel. Also, reboot once more after the flashing. the phone doesn't go into deep sleep if it is connected to a charger or to a computer. There may be an application running in the background which is preventing deep sleep. In that case you can check which app causing the problem with "BetterBatteryStats" application (search in Google).
Q: do I need to recalibrate the battery?
A: You don't need to calibrate battery for SGS2. Thanks to Entropy512 to pointing out that our device uses MAX17042 which is specifically designed not to require calibration.
OC/UV and init Scripts
Q. What tools can be used to manipulate the clock speeds of this kernel?
SetCpu : http://www.youtube.com/watch?v=X9Sn4Uz4pkM Just an overview
Voltage Control: http://www.youtube.com/watch?v=XkhBFVUKBTQ Just an overview
No-frills cpu: More Info here about the tool
And Initialization Scripts
Tegrak Overclocking app is currently NOT SUPPORTED by this kernel
Q: What is an init.d script?
A:init.d scripts are the scripts which are executed during the boot time. actually, they are meant to initialize and deinitialize system daemons and manage some startup/shutdown tasks. but in android world they are just "autoexec.bat"s. so, it is a mix of rc.d and init.d directories in linux distros. everything in /system/etc/init.d are executed during the booting process. since it is not standard in every android device,some developers choose to execute files starting with "S" and some execute everything. in this kernel, everything in /system/etc/init.d is executed. you can create a script to change, lets say, voltages, schedulers, apply tweaks, run overclocking daemon or run anything else you can imagine.
Q. Okay how do I start to create my own Init.d Script for the kernel?
A: KWERDENKER has written a reference guide to help you get started. You can find his excellent Guide on POST #2 of this thread.
example of Kwerdenker scripts are also in Post 2.
DROIDPHILE'S NOOBS SCRIPTING GUIDE:
http://forum.xda-developers.com/showpost.php?p=19519757&postcount=10699
Here are other examples of init.d scripts supplied by Fenomeno83:
Another couple of nice init.d scripts created by fenomeno83
Q: where is the interface to change GPU clock and voltage?
A:There is now a GUI to change GPU voltage and Charging current it's voltage control and probably one by Gokhanmoral soon
For Undervolting your GPU use this Script from AndreiLux as a Reference:
Example CWM-flashable /system/etc/init.d/99gpuv script
Q: Which governor is the best? Which I/O scheduler is the best?
A: You have to try them and select the one you like. There is a very good explanation about governors and i/o schedulers here:
http://forum.xda-developers.com/showthread.php?t=1242323
HERE IS DROIDPHILE CONCISE GUIDE TO GOVERNORS
http://forum.xda-developers.com/showpost.php?p=19339524&postcount=10023
More info might help those you get a better understanding for schedulers:
https://github.com/CyanogenMod/cm-k...m-2.6.37/Documentation/cpu-freq/governors.txt Source: Cyanogenmod Githubs
Info about Lulzactive Governor.
http://tegrak2x.blogspot.com/2011/07/lulzactive-governor.html
Q: What is smartassV2 governor?
A: It is a governor to control CPU frequency. This governor has a built-in "profile" similar to SetCPU but the profile has no upper frequency limit. It tends to stay on lower frequencies when the screen is off and scale up very slowly, so screen off will use lower clock rate thus conserve more battery, but it also has a fast wake up feature so that user interaction will not see the lag when switching from Sleep to Wake state.... (So SetCPU Profiles are sorta redundant when using this governor, you can still use SetCPU to OC to higher than default Clock frequency).
Q: What is the best UV settings?
A: There is nothing as best UV settings. You have to find the best settings for your device for yourself. Start by decreasing 25mV on each freq and decrease it every day until your device becomes unstable.
Q. I notice one of the features is the ability of customizing Voltages for Charging?
A. Gokhan has written a script which he converted to be applied using CWM recovery (PLEASE BE CAREFUL WHEN APPLYING THIS, IF YOU ARE UNSURE PLEASE ASK IN THIS THREAD BEFORE DOING IT)
Set AC and MISC charging current to 1000mA - CWM flashable (keeps USB charging current at 450mA)
Q. I read that different frequencies would assist in better battery performance do you have any examples of this so I can use it my script?
A. Bene2K11 Created some scripts which allows you modify the bus frequencies when using this kernel, they can be found here:
3 flashable zips for the lowest, mid and highest bus frequencies
MISCELLANEOUS
Q: Which version is the best?
A: supposedly, the latest version is the best. But if the latest version is beta there may be unstable code in it. testing the beta version and reporting bugs will help me. but it's your choice... try and see... maybe this kernel is not stable for your device at all, who knows... I will not answer any "what is the best?" questions and I kindly ask you not to ask that kind of questions since there is no answer to that.
My Thanks for their contribution to this thread to Gokhanmoral, AndreiLux, ChadouMing, Nilste, Matriak31,Ger5,Kwerdenker,Fenomeno83, Bene2k11,Droidphile

[REF]Init-Script Reference Guide By kwerdenker
MANY THANKS KWERDENKER FOR THIS. REPRODUCED WITH HIS AUTHORIZATION.
Original post from kwerdenker here.
I hope some of you find this useful as a reference for creating your own init-scripts. This contains everything I use or at least remember about the options in this kernel. If I forgot something or made an error somewhere, please send me a PM and I will gladly correct it.
How to use these settings:
If you want to test some settings before you commit them to a script, you can use either the adb shell if your on a pc with adb installed or you can use Terminal Emulator directly on your phone. Remeber to enter superuser mode by entering su in the terminal before you try to set anything or you will get errors. After that just enter the line you want with the values you want to test (if the values are incased in "", keep them that way!). If you want to see if it worked just enter cat followed by the part behind the > of the lines and you will get the values that are currently set. Everything you do in this fashion will not survive a reboot of your phone, if you want to make them permanent you'll have to use an init-script. A how-to on that is (currently) out of the scope for this post. Have a look/search in the kernel release thread as there are many examples for that there. I'm sure with this post and these examples you can figure it out by yourself

I will try to keep this post up to date with any relevant changes in the kernel.
Example GPU/CPU undervolting and underclocking scripts by kwerdenker please just use for Reference
Improved version of CPU undervolting script by kwerdenker please just as a reference
P.S.: I will not respond to request what settings you should use to achieve the highest score in a benchmark or how you get the most battery life. This is just to gather the information that is already floating out there. What you do with it is up to you
BETA and RC
beta releases will be available when gokhan releases them
Someone asked in another posting about whats the difference between the governors you can choose in Siyah kernel.
Here is an informative article from Github that explains the difference. The governors are from Cyanogen but I beleive it will give you a fair insight in their caracteristics for Siyah also.
https://github.com/CyanogenMod/cm-k...m-2.6.37/Documentation/cpu-freq/governors.txt
There are also a couple more governors you can choose in the latest RC. Maybe others can give some info. about their caracteristics.
Is it normal, that on 2.1 rc3 i cant see how much juice every app consumes???

Corndude How does insanity do its reporting? is it like miui where you can see the app usage in battery usage section like stock's app manager?
Did you get the stats before on the last kernel you use? I am not on insanity but if I cannot answer your query others can.

i did get the stats before rc3, also doesn´t show the monitor´s use. Insanity is just like cm7, same stuff.

i do not know if it helps but a bit more regarding governors..

Did you just install Rc3 without wiping dalvik? Just want to check . I always do a dalvik and cache wipe before I use CWM to apply the kernel update or If I use Odin to apply the kernel I then boot up into CWM recovery and perform a cache and Dalvik afterwards
Nice thread. Can anybody explain/point me to a good guide on cpu schedulers? This kernel allows changing the scheduler, but i don't know which one is the best for my kind of usage: movies-games-browsing, gpu intensive stuff i guess. Thanks.

Any help is appreciated Mat. Ty for your input
No probs mate.. good idea regarding the thread...At least now the Siyah one can stay just kernel related and all the Q&A can be moved here now..Great job
Issue I had with RC2:
-3G not functional, I didn't realize this until a few hours later when I wasn't at home enjoying my network; tested phone signal, was able to make calls, was in a bit of a cellular black hole but others on the same, and other networks, were able to access data easily,
-Restored my APN's from b/u to address 3G connectivity and at this point I lost all signal, no IMEI, phone number, etc... and would get an FC if I attempted to open the dialer, this was back at home where I have no data issues ever,
-Restored a nandroid b/u and all was good; did not try restoring EFS prior to this.
Just curious what the issue might have been; EFS corrupted (seemed to be a step wise loss), other?
And yes, at this point I realize I should learn a lot more before testing betas, etc... it's on my list Other than that I was thoroughly impressed with the lulzactive governor.

Siyah wipes it all by itself when installing via cwm.

What rom you using?
I am on RC2 on Miui as far as I am aware I did not think it would interfere with EFS or change modem. Was there any think else that might have cause the EFS corruption or APN changes.

You tried clear data on the app manager and reboot the phone?
i have this problem whereby UV settings are applied during boot. am using init.d scripts. it sticks for 5-10mins and then it automatically reverts back to stock values. anyone else facing this prob?
am running gingermod 0.7

I'm on DlevROM (XXKI4 based); Siyah 2.0 does back up EFS, so there must be a chance for corruption somewhere along the line.
