Introduction:
This module implements undervolting for the stock SE kernel of X10 based on the latest baseband/kernel.
From Wiki: Undervolting is the term used when the voltage of a component, usually the processor, is lowered in order to increase stability and/or reduce temperature.
Undervolting can also result in better battery performance, which is actually the reason to use this module.
Notes:
This module is based on doixanh's ingenious hijacking of kernel calls which has proven precious for X8/X10mini owners by helping us enhance our devices (e.g. undervolting, overclocking, dual touch), see: X8uv.
My friend, My_Immortal, is supporting with testing/debugging this module.
She asked me to work on that and without her help and patience it wouldn't have been possible. Thank you very much My_Immortal

Yes, we do have custom kernels for X10 - this has nothing to do with those and it won't work on those.
If one of the posted version works for you, keep it, no need to try the others! Basically try them in this order: v.001 -> v.002 -> v.003
In case you want to uninstall this mod, go to xrecovery -> partition tools -> mount /system -> flash the attached uninstall_uv.zip and you are back to normal!
Requirements:
- Rooted
- xRecovery preinstalled
- Baseband > 52. (If you are using an incompatible BB, you will get battery drainage issues. You can see this via 'lsmod' from adb shell with the module reported as 'loading')
Installation:
Automatic:
- Flash the attached zip via xrecovery. (Note that you need to have a ROM with a /system/etc/hw_config.sh script, I think every stock/custom ROM has this)
- Enjoy better battery life
Manual (via root explorer):
My_Immortal said:
From the zip take the x10uv.ko and copy it on /system/lib/modules.
Then, go to /system/etc/hw_config.sh, long-press on it, and select Open in text editor.
Add the following line:
insmod /system/lib/modules/x10uv.ko
Save & Exit
Delete the .bak file that Root Explorer created.
Exit, reboot the phone

Sorry, but what exactly do you mean by "latest baseband"? Version .58?
Undervolt for Stock? I thought Bootloader crack/bypass is required for Undervolt?
@OP: Could you elaborate how it works? Thanks!
@ Devs: This could be an addition for every rom out there?
Think ill backup and give this a test!
@[email protected]:
Do you plan to port X8Overclock for X10? It may prove useful until custom kernels will become stable.
Im on baseband 52. Can i use it?
Sent from my X10i using XDA App
great to see devs from other Xperia devices helping out here...
Nice work.

I'm not quite sure which basebands are compatible, sorry
I built this module using the 2.1.A.0.435 kernel sources by SE.
So then it will probably work on BB 54,55 and 58 so the latest should work all.

OK, that's good enough. Any sources/git repo available?
This is for undervolting the stock kernel, yes. We are hacking our way for this to work
Basically we reduce the voltage levels for each available frequency. I'll post the moded voltage levels vs original ones shortly.
I know for sure that it works on Trip's CM6 rom (which My_Immortal uses). To be honest, I don't have an X10 device

I will look into overclocking too in the next days if it's useful for you guys.
We, the mini users, do have overclocking (600Mhz -> 768Mhz working without a glitch), and fake dual touch thanks to this hack

So it seems to be really useful and quite powerful. Well, at least it's more stable than current custom kernels.
Will this work on Wolfbreak's CM6.1.3 (Android 2.2.1)? I don't dare to try yet. Need my phone and don't want to reflash in case something goes wrong.
OR
Does this works only for 2.1?

I've been working with doixanh on netfilter but we got stuck.
Basically we hijacked all needed calls but we got lots of panics at many occasions (e.g. when x_tables.ko was loaded, unloading the wifi driver would cause a panic).
This belongs to another thread though

Beware! After overclock, you will feel a bit hotter than before and battery drains much faster!! Flash it at your own risk.
What you need to do is:
1) Install SDE
2) Get the initramfs from this post (download the kernel+init.zip and extract it): http://forum.xda-developers.com/showpost.php?p=9948644&postcount=1
3) Replace the zImage with the new overclocked kernel
4) Boot into SDE recovery menu and copy the initramfs.cpio.gz and zImage through USB cable
5) Boot into SDE developer OS
6) You should get all your apps here and have superuser right now
You will now have read/write access to /system/ or /data/ ...etc.
Next step: You can download GScript from the market (free) to make some custom scripts to remove unnecessary apps and replace the hosts file, etc.

Give us a "Thank" if you think this kernel works great for you

Oh thanks man! I'll impliment this into my own version of Auron's, yeah there was some confusion about your method, thanks for clearing that up!
Nevermind XD I don't know enough to add that, but Auron heavily uses EXT4 which he compiled into his kernel, which is probably why it isn't working for you, he explains in his topic the things he did or did not do.

Thanks. BTW, it would be good if Auron will release his source such that we know what exactly is changed apart from the EXT4 things.
New kernel updated!!!
Get it at the #1 post
Now, it is EXT4 support and can be used together with $aur0n initramfs !!!
Down-clock to 1100Mhz seems to make it more stable
Thanks man really appreciate your quick work! works perfectly with Auron's
Although I'm curious how that overclock works, I've read up on it and it seems that everyone else is making overclocking modules etc. your solution seems a lot more efficient. Do other people know about it too?
I first though it was just a soft change, something that didn't affect the hardware, but something that just forced the digit 1100 instead of 1000, this doesn't appear to be the case since I get some speed gains in Quadrant
~ benched a 2438 ^^
edit: is it possible for you to change the LOWEST value as well? i'm not sure how it would react but I imagine a 100Mhz/200Mhz feature would save up some standby-battery-usage also is it possible to change the intervals with this method? so that we can get 300/400/500/600/700..1100?
edit2: would it be theoretically possible to compile a kernel with driver support for gamepads and others? perhaps ntfs-3g to mount ntfs external drivers... thinking about this we have usb host on this device and an open bootloader

The most difficult part is to determine how much voltage to be given to each frequency. So, it would take some efforts to study.
In addition, setting too low frequency is not necessary be good because the machine might go into deep sleep and never wake up.
Have you run any Super PI tests (or something similar) to see if there are stability issues with the increased clock rates?
Typically when I over-clock my CPU on my PC I increase the voltages at the micro or mini level (CPU, Front Side Bus, Memory, Memory Controller, etc.). As an example 1.3500 may not be stable but 1.3501 could be. Typically You can find the voltage tolerances typically at CPU manufacturer website (ie Intel for me). of course you also have to deal with the temperature of the CPU and other supporting components that regulate the voltage. I will run a Super PI type application to test stability for a few hours. If it works then dont add voltage.. if it comes back with a miscalculation OR an application/OS crash then increase the voltage by a micro amount...
You are correct when you saw it not performing at a higher clock rate... typically what happens if the CPU does not have enough voltage to perform at the expected clock rate it seems to throttle the execution rate to ensure some level of integrity of the executing transaction..
Unfortunately over-clocking is not a science..

its using the same cpu as a lot of android phones are and i daresay that most of the work (working out optimal cpu voltage etc) has already been done
The question is for non-standard clock rates. Standard clock rates should have well defined voltages.

While this kernel has been OC, it only allows you to choose higher frequencies. BUT, you can still choose 1000 Mhz as the highest by setting it in SetCPU.
After setting min/max as 1000Mhaz in SetCPU, this kernel is just like any other kernels, except that I have applied some of the newest kernel patches (fix bugs?) so that this kernel MUST be better than the stock one.
Hope you enjoy using it
no no, the problem is that after installing oc kernel(without touching anything about frequency), angry birds doesn't run and asphalt 5 doesn't run well and it closes when init a race...So, what's the problem? I have returned to original kernel(with rooting), and now are perfectly running(angry birds and asphalt5)...

It is quit strange, coz I can run angry birds, dungeon hunter, etc.. very smoothly even when I use 1100 Mhz, have you tried to install SetCPU and set the frequency?
Any one have similar problems?
Working great on my A101! It's subtle, but I do notice a slight performance increase in pocket legends. Keep up the great work ardatdat!
ok so i did it and now the youtube app freezes up with 1100 or 1200 mhz...the video plays for like 3 or 4 sec and than freeze leaving only audio playback.. video plays normal at 1000 mhz and down...

i still have probs with forced closes on boot so i set the voltages to "SEMC Default" (1200mV on 1024Mhz) to make shure that to low voltage dont cause problems !!! it seems that it cured my problems at boot. i you like to undervolt use a prog like SetXperia for this.
here the values from orginal 4.0.1.A.0.283 sources-->>
Code:
{ 1, 806400, PLL_2, 3, 0, UINT_MAX, 1100, VDD_RAW(1100), &pll2_tbl[0]},

BTW i use [email protected] for v2 now!!!
because of my probs with voltage at boottime and because doomlord doesnt plan further development i tryed to compile doomlords sources
BTW really big thx to DoomLord for your Hard Work !!!
at this point i like to share my first selfcompiled Kernel for NEO stockrom 2.3.4 based on DoomLord's sources.
i made a few tweaks:
-removed swap support (because swaping to /cache partion does not work so its useless)
-removed unused govenors (i leave smartassv2 because i thing it is the best ;-) )
-set smartassv2 as default govenor
-set noop as default scheduler
-raised the voltage for 1024mhz from 1000mv to 1100mv (for stable booting)
if you try is Kernel you do at your own risk. but everything should work if you follow DoomLords guide in this thread-->>

max is 1.8 ghz because 2ghz is unstable . i think its for arc-s witch comes with 1.4ghz default. so i removed it,else neo would boot with 2ghz on 1.47 volt and this is useless imho
you can set voltages with SetXperia i use smartass2 for powersave on 800mhz with threshold set to 99%
for 24/7 use i set samartass2 max 1.4ghz with a threshold of 85%

I love this, nice work, and thanls for Support C:
Smartass2 for Powersave? ok.
And which Profile for Normal?

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.
THANKS:
Samsung, supercurio, hardcore, Hacre, RAvenGEr, tegrak, cattleprod, codeworkx, hellcat, creams, vitalij, arighi, ninpo,netarchy .. Any others that I missed.

Custom boot animation support
Supports SetCPU (OC upto 1600MHz, UC downto 100MHz)
User customizable frequency steps. You can edit "freq_table" and use 25MHz as the lowest step and 1696MHz as the highest. You have 8 steps (it is fixed) but the frequencies can be set.
Supports undervolting (UV between 800 mV and 1500 mV)
Supports voltage control via SetCPU (thanks to netarchy, ninpo, hacre)
Stock voltages as default
smartassV2, lulzactiveV2 governors. and lots of other governors which are available as modules
Default governor is lulzactive (200-1200MHz)
Tweaked ondemand and conservative governors
no compiler optimization. it is just a myth.
Touchscreen fix (thanks to vitalij)
Increased touchscreen sensitivity
GPU clock (thanks to netarchy), voltage and scaling thresholds control interface.

Charging the battery stops when the battery draws less than 100mA (stock value is 200mA).
CIFS, SLUB, FUSE, NTFS, cgroup_timer_slack, autogroup,... and lots of other mambojambo that I forgot...
TO FLASH ZIP:
Use CWM Recovery and install zip file. Wiping cache&dalvik cache is recommended for those who use BLN.
if you lose root after flashing the kernel (unlikely), flash http://goo-inside.me/superuser/su-2.3.6.3-efgh-signed.zip in CWM.
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:

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

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???

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.

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.

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.

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

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.

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.

New UPDATE 13-07-2012: Youtube fixed, CleanCache include, Gov Optimisation, include Interactive Sched., remove SIO Sched (unstable ATM) => PLEASE REPORT
Hi guy,
I would like to share my work and try to see if my hardware is limited to OC.
I can OC with great stability to 1080 and 1100 with little crash (after 2 days of use). 1150 and 1200 no boot.
Kernel include:
-Based on 2.4.83 Archos kernel
-SIO - BFQ Schedulers include - BFQ by default
-Lagfree and MinMax CPU Governor include Conservative by default
-OC to 1100/1150 with 300/600/900/1010/xxxx step Frequency
-OC to 1200 with 300/600/1000/1100/1200 step
-Ext4 - you can applied WhoDunnit's tutorial
-Jenkins hash support update (less CPU consumption)
-Completely Fair Scheduling (CFS) upgrade better stability
-Others tweaks (I don't remember all ^^)
You can choose step, SIO, CPU Gov. with Voltage control.
The kernel is compatible with A43 - A70S/H/IT/IT2 - A101 and works well on BULL RC or Original Firmware from Archos. I CANNOT TRY IT WITH URUKDROID (My device hasn't same partitions :s).
You can download Kernels here:
V0.1 => 1100MHz: http://www.mediafire.com/?421uilfwbhx2em3
V0.1 => 1150MHz: http://www.mediafire.com/?u9bx28132jwln0c
V0.1 => 1200MHz: http://www.mediafire.com/?ta2f7m64d7aor4j
UPDATE:
V0.2b => 1000 Swap is useless on ours devices and compcache need more ram. I upgrade the voltage of CPU, and try to oc to 1200
UPDATE:
V0.3 => SEE LAST POST (kernel are attached on it)
How to use:
Just rename it to zImage and install it with your favorite initramfs.cpio.gz ( Bull or Archos) on SDE Menu.
I AM NOT RESPONSABLE IF YOU BRICK YOUR TAB. Thanks .
Kernel works fine on my tab, but i can't assure that's similar on others tabs.

WORK IN PROGRESS ACTUALLY:
-GPU OC => think that the freqs are hardcoded by register (see OMAP3630 doc)
-GPU OC => BUS MEMORY OC, but don't know if it works in reality.
-STABILITY IMPROVE => Clean the code!!!!!!
-YOU TUBE WORKS

Say me if you have any pb at 1150 and 1200Mhz please
I must clean the code and undo modifications to oc gpu (it is oc to 230Mhz and memory bus but it doesn't worked).
I find the 3d perf bad.

Are you planning future improvements? I can help you testing it. Glad to see improvements for our devices.
I will try it later and tell you the results, going to try all of the kernels and check the stability.
EDIT: The device didnt boot with 1200 zImage.
EDIT #2: A question out of the topic. Is using swap going to kill my SD card faster?

I have made this kernel because archos stop dev of ours devices. I am not a great dev lol, i haven't developped code since 10 years . But i have a brain, and try to use it
I would like port LiveOC code to our device, it exists for i9003 equiped with omap3630 but the code to select frequency is very different, i don't know if i can do this.
And port Smartass2 governor. The code is included in the kernel but desactivated i have lot of errors.
I try to oc gpu ATM, without result...i think that the freq is cable in the hardware...
My purpose is to know if ours devices can go up to 1100Mhz with the actual code. I need tester :thumbup: !
OC stability can changed for each devices.
Edit: Is it stable with 1150? I have crashed when i used wifi strongly. Like a big dl.
Verify that you have all frequency active with voltage control.
Edit2: i think that you will have changed of tablet before the sd die

I will check 1150 when my tab is fully recharged. When I disconnect it when its half charged the calibration goes crazy.
Thank you very much for this.

Thanks in advanced!!

I tested all the zImages as I said and the results are:
1100 is stable without any problems.
1150 isnt stable with many problems, the first time the boot hang on OpenAOS logo. The second time I couldnt enter settings. The third time it hang when I entered settings.
1200 doesnt boot at all. Reboots on OpenAOS logo.
Keep up the good job, dont get disappointed.
@bizcuite:
What vsel's are you using for the frequencies?
I know from the Milestone that we had a wide variation of vsel's that where working on diff devices.
If you look into the oc posts here you see that ( when we had that on from sibere ) vsel=80 was working for many at 1200MHz

I use 64 (0x40) ~= 1.38v. I will try differents steps to OC to 1200 my Tab.
I have seen a table of vsel by freq on TI website, i must find it again!!
Thanks for information
Edit: i have tried it with 75 and 80, no boot at 1200....
Bizcuite
First its nice to see a dev taking care of our tablet
And thank you so much for that !
I've just formatted my tablet (was having lags and lots of crashes) and installed your kernel over OpenAOS (the last non-official build) and wahouh !!
So smooth !
I've installed the 1100MhZ, I'll run it for a day and after I will test 1150 and 1200
Thanks again dude !
NEW UPDATE: CompCache and Swap Enable
NEW UPDATE - SEE FIRST POST:
CompCache and Swap enable by default
1 GHz ONLY FOR TEST
1000 - 1100 - 1150 - 1200 - released later if test are good!!
EDIT: if you want to see if Swap is active just download terminal emulator on android market and tape: free
PLEASE REPORT IF IT WORKS ON YOUR TAB.
Edit2: swap doesn't work and is useless :thumbdown:
Bizcuite
Thank you Bizcuite for your kernels. I tested your 1100 kernel on my A70 running cm7-bull and the speed was very good. I have found the kernel seems to break something with video streaming apps. TvCatchup, Vulkano and Youtube (LQ and HQ video) all fail to work but work fine with the original cm7-bull kernel.

Right!!
After read this article from Wiki, we don't need this: http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache.
Swap and compcache are disable and code is erase.
I will upload a new version with better VSel values and original GPU driver (It was a test with i9003 driver and OC :silly: ).
Bizcuite
Ok. Waiting for you to upload the updated zImage as it seems I have a day off.
EDIT: Lets reach 1.5GHz
Bizcuite could you upload your sources to github please?
And what does that mean ? (on hte build config)

Known problems:
Some users get a "kernel panic" at boot time, I don't know why this happen and I don't know how to solve it ..
Offline charging isn't working

I've got problem with github, source code is on gitorious.
nice
usb otg is not working..its now smooth i hope it saves battery

Thanks for the feedback
The pegasusq governor will drain more battery then the stock kernel now.. I have to optimize it.
You can set smartassv2 with setcpu/antutu cpu master, it will save battery.

yes i have changed it to smartass v2 ..i didnt get kernel panic ..i hop you continue to add some more features ..and what does this means "/storage/external_SD/Android/data" will be mounted in "/storage/sdcard0/Android/data" at boot time.
"/storage/external_SD/Android/obb" will be mounted in "/storage/sdcard0/Android/obb" at boot time.
Where are sources?

Would it be possible to incorporate on your kernel a patch for 2WCR support (2 Ways Call Recording) ?
This don't work for me.

You're right... I'm fixing it in the next version. You can mount that directories with this command (terminal emulator):

I will try to add 2WCR.
Yeah, 51.1 fps in Epic Citadel benchmark. On stock gpu there was 44 fps, so the oc works.
Thank you for fast reply, great work and keep doing.
Can you readd the 1300 step?

thanks finaly a kernel for stock rom that what we need^^
i will wait till it's some sort of stable thing, i have the time, hope you will keep updatinh the kernel etc
thanks to the dev for this work.
i will flast, test and report, but the downloadlink is broken for me?!?
What is the different of battery between this kernel and the stock kernel? Will it still draining the battery while using WiFi like stock kernel?!Can anyone post the battery stats screenshot with this kernel?!, I am quite interested in this kernel, I will try it later. BTW thx for your developing
