Read the Known Issues section of this post below along with the FAQ a few posts down before posting.
A few people have asked about I9100 builds of my Daily Driver kernel for the SGH-I777. I normally hate blind development, but since most I9100 guys are doing it for I777 targets, I may as well try going the other way. Since it fails the definition of being a "daily driver" as I own an I777 and not I9100 - it will not be using the Daily Driver name.
This should be compatible with most stock-derived Gingerbread firmwares, with a few exceptions listed below. It is NOT compatible with CM7/MIUI or any other AOSP-derived firmware. It is NOT compatible with ICS and WILL NOT BE until ICS kernel source for the I9100 is released. At that point a new thread will be created for those kernels. I am testing it currently with self-deodexed/debloated/Hellraised XWLA4.
The following firmware bases are likely to deliver poor battery life with this kernel due to wifi bugs in the firmware:
XXKI3, UCKK6, XWKK5 - especially UCKK6 and XWKK5
This kernel series is intended to be similar in spirit to my Daily Driver series for the Infuse at http://forum.xda-developers.com/showthread.php?t=1212795
It is built from sources at https://github.com/Entropy512/linux_kernel_sgh-i777/commits/oc_codeworkx, and initramfs at https://github.com/Entropy512/initramfs_sgh-i777/commits/master
My general goals are to focus on stability and battery life. If it comes to a tradeoff between performance and the above two, I will choose stability/battery life. In general I will choose stability first, with the exception of undervolting.
I keep my initramfs clean - There are no tweaks or other automated scripts built into this kernel. For a collection of tweaks I am working on and documentation on them, see http://forum.xda-developers.com/showthread.php?t=1378080
Current features:
I9100 Update3 base
Touchscreen drivers from I777 source code base
codeworkx's cpuidle patch - should improve battery life a bit. In most cases it will likely not improve things much, but in rare cases it will result in significant improvements. (I only have one partially-reproducible test case on the Infuse so far)
JHash 3
BFQ I/O scheduler
CIFS module in initramfs
CWM 5.0.2.8 compiled from CM7 sources on 2/28/2012
"insecure" kernel (meaning root in ADB)
CPU governor set to Conservative by default to conserve some battery - this will make your device slightly less responsive, use SetCPU or a similar app to return to ondemand if you want it, or reduce the conservative polling interval
Filesystem readahead tweaks in initramfs
netarchy's Sleep of Death fix
netarchy's conservative governor tuning patch - should improve responsiveness of devices when using the conservative governor if you reduce the polling interval (misnamed as sample_rate) - the I9100 community calls this "lionheart" even though it's really only a 2-line patch
Battery charge current monitoring (CurrentWidget) support - only reports charge current and not discharge, and reports a value 2.85 times the actual current. Use CurrentWidget's "operation on value" to divide by 2.85.
Miscellaneous bugfixes pulled from Ninphetamine and CM7 sources - see github for details
/system/etc/init.d support in initramfs - Note that this only runs stuff in /system/etc/init.d - ROM developers or you need to create it. Attached is an example script that will change the CPU frequency governor to ondemand if placed in /system/etc/init.d and set to executable
Four "use at your own risk" features that trade performance for stability - See Post #4 for details
Standard bootanimation support
/proc/last_kmsg crash debugging support
NFS modules in initramfs - note that they must be insmodded in a specific order: sunrpc.ko, lockd.ko, then nfs.ko
Fix for fuel_alerted perma-wakelocks
Fix for wifi tethering on I9100 ROMs that have been Hellraised to I777
Bump up TCP buffer sizes in initramfs to match that of the Infuse - may help network performance in some cases
cpuidle driver from Tab 7 Plus kernel - allows entry into AFTR more often - includes MFC interoperability fix (Should not break video playback.)
Support Bluetooth HID on newer firmware bases
3-step GPU clock/voltage control
Extended hotplug tuning
Support for Xan's ExTweaks universal tuning app - https://market.android.com/details?id=com.darekxan.extweaks.app
Planned features, short term:
Determine if issues with PINlock when running I9100 firmwares on I777 have kernel involvement, and fix them if this is the case.
Planned features, mid-term:
Potentially my first departure from "standard" governors, with a focus on improving hotplugging logic
Planned features, long-term:
Improved battery charge algorithm for faster charging - Initial research indicates we have an alternate battery charger chip (MAX8922) that differs from the MAX8997 used in the I9100. We DO have an 8997 also - but on our device for some reason Samsung decided to use an alternate chip instead of using the 8997's built-in charging. This means we have far fewer options (90,400,660 mA) in terms of charge rates compared to the I9100 (from 200 to 950 in 50 mA steps). So we might not be able to implement any fancy charging algorithms.
Features not planned:
BFS process scheduler - I have only once ever seen a test case where this clearly outperformed the mainline Linux scheduler (multithread x264 encoding) - The mainline schedule was fixed in the next release and BFS now has no performance benefits
Any feature that trades off stability or data integrity for performance unless it can be disabled entirely and defaulted to "off"
Any feature that cannot have functionality tested without a paid app. Interface-only checks don't cut it - I don't want users complaining that the app they paid for didn't work because an interface check worked but function didn't
Touch recovery - too prone to unintentional user input in dangerous situations. I will reconsider this with ICS.
ARM_TOPOLOGY/SCHED_MC - See http://forum.xda-developers.com/showpost.php?p=23193259&postcount=100 for details
Known issues:
Power management regression somewhere between 12/8/11 and 1/2/12 - Intermittent high drain without high AOS or reduced deep sleep percentage when on some wifi networks - seems more likely if GPS is used when connected to wifi. Wifi with high AOS/reduced deep sleep is not a kernel problem. This appears to only happen on some firmwares - it happens on XXKI3 but not XWKL1. It is likely connected to a wifi power management bug in some firmwares. A debugging feature in 2/7 and later will allow identification of such firmwares - see http://forum.xda-developers.com/showpost.php?p=22581928&postcount=1777 for details
Some people have reported touchkey lights becoming disabled until the screen is turned off and back on again. Under investigation - seems to mainly happen on firmwares with BLN-modded liblights even if the BLN app isn't used
Internal and External SD card are swapped in CWM currently
Keymap is a little funky in CWM for I9100 users. VolUp/VolDn to move, Power to select is reported to work, but bottom keys are funky. Working on it
A few users have reported that when Hellraising I9100 firmwares to I777, they are unable to set up a PIN-lock. If this occurs for I9100 users on their own devices, I need to look into initramfs fixes and this will be my top priority.
Basic flashing instructions for .tar releases (NOTE - There are currently no releases in this category. These instructions only remain for heimdall+ZIP users:
(Tested on Linux, not tested MacOS/Windows but should work) Heimdall - Extract the contents of the tar file, enter download mode, and flash with the following command line:
Code:
heimdall flash --kernel zImage
Flashing instructions for .zip releases:
Flash in CWM, or extract the zImage and use the Heimdall instructions above.
Please do not ask how to enter download mode or install Heimdall/Odin in this thread - these are basic generic skills anyone flashing custom firmwares on Samsung devices should know and plenty of documentation exists elsewhere. If you really need to ask, use the General forum, or if created, the Q&A forum. I want to try to keep this thread clean and only with bug reports and issues specific to this release, not general HOWTO or troubleshooting posts. Some of the information you need is in jivy26's FAQs thread at http://forum.xda-developers.com/showthread.php?t=1288112 - Reading at least the first post of this thread in its entirety is STRONGLY recommended.
Bug reports:
If you have a crash (reboot all the way to Galaxy S I9100 screen), use ADB dump the contents of /proc/last_kmsg and post
If you have oddball behavior, include a clearly reproducible test case with your report, or use ADB to obtain a dmesg and logcat capturing the odd behavior at the time of error.
Similar to flashing - using ADB and obtaining last_kmsg, dmesg, and logcat dumps are basic skills that anyone working with custom firmwares on Android devices should have. If you need help with these, do some searching, or post in the General forum or Q&A forum.
Firmware ("ROM") Developers:
While I cannot restrict anyone from putting this kernel into a ROM as long as links are given to the github sources for GPL compliance, I request that anyone who includes this kernel in a firmware release does the following out of courtesy:
Link to this thread
Clearly indicate in your firmware changelog which Daily Driver kernel release is included in your firmware release whenever you change DD releases - this lets users identify whether a fix is present in the kernel they're using or not
Kernel Developers:
Similar to my request for ROM developers, while I can't restrict you from doing anything, I ask as a courtesy that if you cherry-pick my commits, you do the following:
Please don't rebase my commits into a large multi-feature without consulting me - rebasing related bugfixes together is OK.
Please try not to implement lots of unrelated features or bugfixes in a single git commit - it makes it hard to reimplement that when Samsung drops new sources or releases a new device
ALL OF MY RELEASES ARE NAMED BY RELEASE DATE - MMDDYYYY. See the changelog for differences between Experimental (exp) and non-exp versions for days where dual releases are made.
Change Log
The primary change log will be kept in my I777 kernel thread at http://forum.xda-developers.com/showpost.php?p=18129037&postcount=2

Here Be Dragons
This post is for features present in the kernel that are "use at your own risk" - They have either potential or guaranteed negative side effects if used.
Overclocking (CPU):
Enable using SetCPU or a similar app
USE AT YOUR OWN RISK. DO NOT REPORT BUGS OR PROBLEMS IF YOU ARE OVERCLOCKING OR UNDERVOLTING. IF YOU EXPERIENCE ANY STABILITY PROBLEMS, DISABLE ALL OC/UV
Overclocking (GPU):
See Ninphetamine kernel for documentation - Same control method
USE AT YOUR OWN RISK. DO NOT REPORT BUGS OR PROBLEMS IF YOU ARE OVERCLOCKING. IF YOU EXPERIENCE ANY STABILITY PROBLEMS, DISABLE ALL OC
Per-File fsync() disable:
This allows you to disable per-file write forced syncs. (e.g. if an app tries to force a write straight to disk, it'll just go to cache). This achieves the same goal as the modded sqlite hacks seen in tweaks such as USAS, however it can be disabled at runtime.
WARNING: THIS CAN CAUSE DATA LOSS OR CORRUPTION IN A CRASH
To enable, do the following in a terminal, or add it to an init.d script (look at my ondemand script as an example):
Code:
echo "1" > /sys/module/sync/parameters/fsync_disabled
And to disable (return to the default):
Code:
echo "0" > /sys/module/sync/parameters/fsync_disabled
Good for around 200 points of epeen in the database benchmarks in Antutu or 500-600 points of epeen in Quadrant. Real-world benefit: Probably not worth the data integrity risk, but you've got a choice now.
Backlight Notifications (BLN):
This allows the touchkey backlights to be used for notifications. Some stock apps (such as stock MMS) don't support it. Supposedly services.jar mods can change this.
This WILL drain your battery when a notification is active due to a wakelock that holds deep sleep. Sorry, it's either this or instability for the time being.
In addition to the BLN control app, the ROM needs a modified liblights file for this to work
Attached here - Liblights - both BLN-modified (extracted from VillainROM 3.0) and stock I777
To install, take the file and push it to /system:
Code:
adb remount
adb push <file> /system/lib/hw/lights.SGH-I777.so
adb chmod 644 /system/lib/hw/lights.SGH-I777.so
Then reboot
Note that on a Hellraised ROM, you need to replace SGH-I777 with GT-I9100. This includes manually ported ROMs like Cognition 777
Like my prerooted system image, this file is compressed using 7-Zip to prevent people from trying to flash it with CWM
OK, right now this post only has documentation of one "special but safe" feature:
To enable debugging of high deleted_wake_locks time, I've set this up to allow wake_lock_destroy() to be debugged without enabling DEBUG_WAKE_LOCK (which spams dmesg with a ton of stuff not needed for wake_lock_destroy() debugging). To enable, add 32 to the value of /sys/module/wakelock/parameters/debug_mask - This defaults to 3, so the proper value is 35.
Code:
echo "35" > /sys/module/wakelock/parameters/debug_mask
Return this to 3 to set it back to the default.
With this, you'll see wake_lock_destroy debugging information in your dmesg output. This is only needed if you have very high deleted_wake_locks times.
The following is known to cause deleted_wake_locks:
Turning off wifi will convert all wlan wakelocks into deleted_wake_locks
FAQ
Q: I installed this and still don't have root?
A: I keep a clean initramfs. There are NO tweak scripts in it, and no autoinjection scripts. To root your device, flash one of ChainsDD's Superuser packages in CWM
Q: I don't like the default I/O governor, why is it this way?
A: Clean initramfs (if you need to flash a kernel cleaner script after my kernel, I have failed or an app cluttered up your init.d) - If you want to change the default governor and tune the filesystem, see my init.d scripts thread.
Q: Why is it so laggy by default?
A: I don't believe in having half my patches tuning default values of things the user can change. In addition, as stated above - battery life is valued over performance, so default governor settings will be biased towards battery. My personal recommendation if you wish to increase performance (at the cost of battery life) is to drop the sample_rate for the conservative governor using SetCPU or a similar tool - this will significantly improve performance. It provides nearly all of the benefits of the original "lionheart" without allowing the sample_rate to go dangerously low. In a future release I'm going to drop the minimum a little bit more.
Q: Something went wrong. I'm using some stupid comprehensive tweakscript. Y U NO FIX?
A: I will not support anyone who is using a comprehensive tweak script (Thunderbolt, V6 Supercharger, etc. - ESPECIALLY V6 Supercharger, as its developer has multiple times in the past put in dangerous tuning options. For example, he disabled the panic reboot timeout, which combined with Samsung's ****ty wifi driver on the Tab 7 Plus, led to multiple Tabs draining their battery all the way to the battery's failsafe cutoff.) If a specific individual tweak causes a problem, let me know - but you'd better know EXACTLY which tweak it is. In addition to the above issues with V6SC, many "tweak scripts" achieve their goals by trading filesystem integrity for performance, and irresponsibly don't warn the user about this fact. See, for example, the fsync disable feature above - it's dangerous, but don't say I didn't warn you it was.
Q: What voltages do you use?
A: This is irrelevant. Every device is different, if a given set of voltages worked on all devices, Samsung would've made it stock. I will report any discussion of voltage recommendations to the moderator for cluttering the thread. If you're undervolting, you need to take responsibility and do it on your own.
Q: Why don't you support AOSP firmwares (CM7, etc.)?
A: I know that the CM team frowns upon alternate kernels as it makes their testing job more difficult. Similarly, supporting too many firmware bases makes my job more difficult. Out of respect for the skills of codeworkx and atinm, I will not release kernels that could make their life harder. I periodically give them the heads-up on patches that I think are important though.
Q: What's with the toilet humor of the name?
A: Long ago in the Infuse community, there was a person (lemons) that was starting to do some smali hacks (camera modding and such), and was planning on eventually releasing a ROM. He was a pretty good guy, and had lots of potential. He and others joked that since it was his first attempt, it should be called ****ROM. Sadly, lemons never followed through and just disappeared, so for months, ****ROM never became a reality. Eventually it was realized in the form of a deodexing/porting/basic modding guide for I777 users at http://forum.xda-developers.com/showthread.php?t=1505685. In addition - I hate hype and marketing, better to set expectations low and let the code prove itself on its own merits. Since I'm blind-developing, I can't just say it's my daily driver because in this case, I am unfortunately not eating my own dogfood.
Q: Why don't you base on 2.6.35.14?
A: That would be my Experimental series. It's temporarily on hold for a variety of reasons but will return once I finish reimplementing some patches. The great thing about git branching is I've been able to maintain .7 and .14 trees simultaneously with ease.
Q: Sometimes my touchscreen is unresponsive right after a wakeup, why?
A: It seems, based on reports from khartras and teiglin, that TouchScreenTuner does not play well with the I777 touchscreen drivers. I'm not sure if it's even necessary with them - in the months since October, the only time I have ever received touchscreen complaints from I777 users was when running I9100 update3 touchscreen drivers. TST may just be working around broken drivers...
Reserved for ?????
Thanks for this. I will try later.
Again very thanks.

Going to try this kernel for the sole reason that I think you're a great guy on here and I enjoy reading your informative posts - you always seek to educate rather than put people down.
Thanks Entropy.
Uploaded a new release, this has just a few small patches, bringing it up to the same base as Daily Driver 2/26/2012
As a compulsive lurker, reader and searcher, ive been looking forward to this release..
Alongside Pulser and Ninpo, your informative postings and professional ethic enable users like myself to maximize the potential of our devices.
Thanks mate, i have no doubt this will be brilliant..
Thanks Entropy, I've missed your work since I moved from Infuse over here instead of to I777-land. I do have a question, though--I note the only "nonstandard" I/O scheduler you included was BFQ. Do you find sio/vr problematic, or do they just not provide any benefit from your perspective?

I'm considering adding these - I've found that alternate governors/schedulers often cause more problems than they solve.
Thanks for sharing your kernel with us i9100 users Enthropy. I really like your stability+ battery approach. Will be giving the kernel a good go.
Sorry...this kernel is comparible with jkay brightness profile?

No - And right now, I am unaware of any kernel that is. As much as I like JKay's work, I believe he lacks understanding of how screen brightness works on the I9100 and I777.
Even JKay is unaware of any kernels that support those profiles. See entry 12 in his FAQ.
To implement additional brightness steps, an additional gamma table for each brightness step needs to be implemented - https://github.com/Entropy512/linux_kernel_sgh-i777/blob/master/drivers/video/samsung/ld9040_gamma.h
So until FAQ section 12 has clearly defined (and achievable) requirements for compatibility, or JKay declares a specific kernel compatible in FAQ section 12 of his mod, I won't be doing anything. Creating a custom gamma table entry is not easy as it requires a LOT of tweaking and good colorimeter hardware. Supercurio has done it at high brightness levels to my knowledge, but I don't think he's done it for low brightness levels and I don't think he's added extra gamma tables for additional brightness steps.
Edit: I have seen that Speedmod and Redpill do change the table entries for the lowest two brightness settings - however, they don't add any new bins, so the brightness change is achieved even on JKay profiles that don't supposedly require kernel support. e.g. JKay's "dark, requires kernel support" are pointless because the only kernels that actually provide dimmer minimum backlight do so even with his profiles that don't claim to require custom kernels. (And the "super dark" and "dark" profiles will behave the same regardless of kernel.)
What's interesting is hardcore did it for only two of three available panel types. Either two of Samsung's panel types are brighter than others, or hardcore did this without testing on some panel variants and just thought "the numbers are different, I'll change them". I'll look into playing with this as it would be nice to have lower minimum brightness, but it's somewhat low priority as it's easy to simply make things look like **** if you're not careful.
its possible to make your kernel fully compatible with the cmw manager of chainfire
for now some fonctions are desactivate
anyway i m testing it now and all seems to be good
So far so good mate.
Batterylife we will see in a day or two but all in all running fine.
Thanks and go ahead with ur work.
CHEERS ;-)

Although some parts can be considered as original, all are based on inspirations, examples and other people's code.
I have no claim to be original. I am only trying to make my (and probably other's) SGS2 experience better and fun.
I do this for fun. so, if you just want to argue with me please don't. use the energy coming from your youth in something useful.

If you already have root, use DarkyOTA app from the market ( https://market.android.com/details?id=com.ficeto.darkyromota ) .
If not, use ODIN.
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.

Who Should NOT Use This Kernel?
If you are going to use very low voltage settings and complain about having lockups, you SHOULD NEVER use this kernel... just run away! This kernel is just as stable as the stock kernel if you do not modify any settings. Do not blame the kernel if you change the voltage or clock settings. If you do so I will blame your stupidity. I will not remove any feature just because some dumb users select wrong settings. If you are a rookie with an uncontrollable instinct of modifying advanced settings please use speedmod or stock kernel.
This kernel generally contain some experimental code and some of them may be even undocumented. I have different release strategy. I always use the latest version and if I notice any problem I try to fix it. However, I do not use all the features of the phone. So, if you notice any problem please report it. bug reports are welcomed, whining is not.
If you judge a kernel by quadrant score, please, I beg you, don't use this kernel. I don't have enough time nor motivation to answer your questions... Some people got 8000+ quadrant (search the thread) and there is no way you can beat them anyway.. so, go away...
If you are one of those who judges a kernel while sleeping ("oh my god!! lost %1 during sleep"-guy) please use another kernel, sleep and never wake up. it will maximize your battery and minimize the tension in the thread.
If you still believe in battery calibration, discuss it in some thread else. we respect all religions but missionary acts are not welcomed in this thread.
99.9% of the code belong to others. I have some modifications and/or additions to the kernel as C code or scripts but they are so little compared to the original code base. If you think you are better developer than I am, don't waste your time (and mine) as I accept it beforehand so please just go away.
FAQ
Q: Does this kernel support Samsung's ICS leak, CM9 or any ICS edition?
A: No, it does not.
Q: Does this kernel support latest Samsung i9100 ROM?
A: Yes, it does. Unless otherwise stated, you can use this kernel on latest Samsung ROMs (official and leaks). it is tested on 2.3.4, 2.3.5, 2.3.6.
Q: Can I use this kernel on I9100G?
A: No, you cannot. Only european i9100 models are 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. If you are using another aosp based Rom tell me and I will support it.
Q: Can I use app protectors with this kernel?
A: Yes, you can. Android logger is enabled by default.
Q: Some custom lockscreens or protectors do not work with this kernel. Can you fix it?
A: see the question above.
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: What can I do to have the best battery life ever?
A: put your phone into airplane mode. if you don't like to do it read the guide below.
Q: Which roms are supported?
A: All android 2.3.4 and 2.3.5 roms are supported. Try the latest version. if you have any problems leave a post to this forum and ask for help.
Q: I get random reboots or freezes. What should I do?
A: Before reporting any problems you have to make sure that you are using stock voltage values. Some phones cannot handle undervolting. Secondly, you have to give details. When did it happen, which rom are you using, can you reproduce it, do you have any custom init scripts which changes kernel parameters such as freq voltage or anything else?
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.
Q: do I need to perform any wipe?
A: no. you don't have to wipe anything. however, try wiping cache and dalvik cache if you have any force closes or any other issues before reporting the issue.
Q: Is the battery life better/worse?
A: maybe... you'll never know if you don't try... People are reporting that they are having the best battery but it may not be the case for your device.
Q: where is the interface to change GPU clock and voltage?
A: There is no GUI (graphical user interface). the interface is used via device files. you have to use init.d scripts to adjust the values. there are some examples in the first post about how to use init.d scripts and gpu voltage/clock interface.
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
Q: My phone doesn't go into deep sleep mode. Why?
A: try to clear cache and dalvik cache by using CWM recovery and make sure that your phone is not connected to a charger. it does not go into deep sleep when it is charging.
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.
Q: How does the automatic battery calibration work?
A: Automatic battery calibration feature is removed as it was useless for SGS2.
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: 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: I want more info about CPU governors.
A: There is a great post about cpu governors (thanks to droidphile): http://forum.xda-developers.com/showpost.php?p=19339524&postcount=10023
If you still want more info, try them by yourself.
Q: Can I use this kernel with I9100T?
A: Yes, you can. the only difference between I9100 and I9100T is that they have different SAR values.
quick and dirty guide to have less battery drain:
- use 2G-only if you don't need 3G
- monitor programs which cause wake-lock. use betterbatterystats and either uninstall or tweak them
- do not use task killers. see the previous item and find the malicious programs instead of repeatedly killing them.
- do not activate google latitude on maps.
- if you don't need pushmail, uncheck gmail sync and use k-9 mail to pull mail, lets say, every 1 hour or so.
- go to settings / location and security. disable "use wireless networks" and "use gps satellites". enable them when you need them, other than that keep them disabled.
- disabling auto-brightness and using a low brightness level helps. do you know that you can adjust the brightness by swiping your finger across the notification bar? try it...
- using juicedefender may help, but it may also cause more drain. test it yourself.
- if you need more speed than 2.5G (i.e. edge) disable HSDPA (*#301279#, select 2 then select 1). you will have 3G instead of H(SDPA) and I think it is fast enough
- disable fast dormancy. dial *#9900# and disable.
- disable auto sign in for google talk (search for talk in appdrawer and use settings to disable automatic sign in)
- disable samsung update and don't use samsung gadgets if you are not in love with them. (this part may be taken care of the rom developers)
- try several radios. I recommend you to try KE7, KG2 and KH3 and choose the one which suits you best. KG2 seems to be the best for me. however, in terms of battery life, there is not much difference between those three.
- be aware that more you use your phone more the battery drains don't complain like "my battery drains quite fast but I did not use my phone. I only played angry birds for hours without making a single call" or don't expect to have a decent battery life if you use your phone as a computer or download torrents using your phone.
i think i will wait 4 feedback because it's based on u2 source.
But good job anyway
cheers

you have to try.
smartassv2 governor with 200-1200mhz setting is very satisfying and the battery lasts at least as long as speedmod-v27 for me.
bfq scheduler maybe
..........will u add it in the next release?
CFQ scheduler really drain too much power.....

I haven't tested it, but theoretically smartassv2 governor that I am using in the kernel should give better battery life than ondemand with a little (not even noticable) sacrifice of performance. you don't need to use any setcpu profiles with smartass governors.
test it. it may or may not give better battery life for you.
I will. Thank you.

Features:
based on JB sources
DISABLED CAP_ERASE (No superbrick bug)
All-in-1kernel because it supports CM9, CM10, Samsung, MIUI and Boot-to-Gecko (B2G) ROMs with a single kernel image. (no Sense4all support)
Dual booting support for all supported ROM types. See droidphile's post for Dual Booting FAQ
Custom CWM touch recovery with swipe gestures and double-tap selection
6-steps CPU freq
5-step GPU frequency levels. VPLL Mode to have additional frequency steps. defaults frequencies: 66-108-166-267-330.
Auto-root. You can also remove root via STweaks app and install it without rebooting your phone again. Auto-root can be disabled as well.
CPU Overclock/Undervolt support (we have two interfaces for that. both of them are defacto standard)
Tweakable vitalij's value (set to 5 as default)
Adjustable touchpad led brightness
Fixed fuelalert wakelocks
You can completely disable android logger using STweaks app
Faster charging for misc and USB modes. There are 3 modes (AC, Misc, USB) and normally last two of them support only slow charging. You can have charging speed of AC by increasing it (especially user while charging in car or using USB port)
Cpu governor optimizations
Gpu voltage, clock and stepcount interfaces (GPU Overclock/Undervolt)
Screen brightness curve settings with original panel gamma values. panel values unchanged, so you will get stock colors and will be able to use supercurio's voodoo display app when it is released. brightness modification will only change auto-brightness response.
BLN support both for Samsung and CM ROMs (you can use STweaks, Nstools or BLNControl app from the market to enable it)
Breathing or Blinking effect for BLN. (Make sure you don't enable blinking in any other BLN app) Use STweaks to select one of them.
Better touch sensitivity
Available CPU Governors: Pegasusq (default), Ondemand, Lulzactive, SmartassV2, Interactive and Conservative, Performance, Userspace, Powersave
CIFS as module
Available I/O schedulers: CFQ (default), noop, Deadline, SIO, V(R)
J4FS as module
ARM topology support (SCHED_MC)
Automatic EFS Backup
Lots of I/O tweaks and filesystem optimizations via some parts of thunderbolt scripts.
USB Mass Storage mode is working in CWM Touch Recovery and you can mount both internal and external sdcard as a disk drive
NTFS automounting for USB sticks. When you plug in an NTFS formatted USB flash it will be automatically mounted to /mnt/ntfs folder.
USB mouse and keyboard support
built-in profile support with default, battery and performance presets (you can change them in CWM Recovery). Even using everything default will save you a lot of battery juice.
Eargasm for headphone amplification (in STweaks) as free Voodoo Louder replacement
Almost everything is configurable such as scheduler features, hotplug thresholds, GPU frequencies, voltages, arm topology modes... and they are configurable via simple and free STweaks app which is embedded in the kernel and soon in Google Play & Opensource
Adjustable mDNIe settings
optional sharpness tweaks from hardcore
mDNIe negative effect toggle with home button (press it four times)
Touch gesture support by Tungstwenty. (http://forum.xda-developers.com/showthread.php?t=1831254)

troubleshooting
READ THESE FIRST
Never report any bugs to CM9/CM10 threads if you use it together with SiyahKernel
Do not ask questions to me directly. This is a common thread, not my personal inbox. Ask your questions in the thread and do not target them to anyone.
Do not expect answers to all your questions. There are some questions which nobody knows the answer of.
Do not forget that this is a development thread. There is another thread in general section for those who wants to discuss battery life and chats. If your post does not include a feature request, bug report or suggestion it should be posted to the other thread.
No ETA for new version. Even if I sometimes talk about release dates those may change and they change for some good reason or because of my real-life obligations.
Make use of "Search this Thread -> Advanced Search"
Never ever discuss anything deep-sleep related in this thread. I do not make modifications to prevent sleep and 99% of deep sleep problems are application/ROM related. discuss it in general section. I do not want any positive ("this kernel sleeps like a baby") or negative ("There is a big problem with deep sleep. Please fix it") messages in my development thread.
If you do not provide details about your configuration and settings nobody can help you or nobody will care about your problem/bug report. The problems without details (ROM, settings, preferably the version that the problem first happened or the one that you don't experience the problem) will be ignored.
Never ever report any SOD issues if you are undervolting/overclocking and make sure you attach last_kmsg log. If you don't know what it is report the problem to the other thread because one more post without any useful information on dev thread will help noone including yourself.
FAQ:
Q: I am having some random lockups with some apps
A: try removing root by using STweaks app and restart.
Q: What is the difference between STweaks and ExTweaks?
A: Both have similar functionality. ExTweak is Xan's implementation of the UCI interface (which is designed by Xan and me with the helps of AndreiLux and implemented in the kernel as open scripts by me) and STweaks is mine. I was hoping Xan would release the sources of ExTweaks (without profile support) but he changed his mind and I decided to open STweaks. Soon they will have almost identical functionality, so you can use whichever you like.
Q: Does this kernel work on XXXXXX-ROM?
A: If the ROM is based on Samsung Stock ICS Rom LPQ or newer, it should. Otherwise, search the thread... If you cannot find any reference to that ROM, try the kernel. You won't lose anything by trying this kernel. Worst case scenario is to reflash your previous kernel or ROM. You can backup your previous kernel with Hellcat's k-tool from the market.
Q: Where is CM9, MIUI or Samsung ROM versions?
A: There is only one version. Both ROMs are supported with a single kernel image.
Q: What is the best settings?
A: It is the one you try yourself and like.
Q: I have just lost 20-30% battery by just rebooting/flashing the kernel. Is it a bug?
A: No. It happens because of our fuel gauge chip which doesn't require calibration goes crazy sometimes. It is not related with kernel or ROM. Just reset fuel gauge chip using STweaks app (or remove the battery and wait 3 minutes) and then charge your phone.
Q: BLN doesn't work.
A: you need to enable it in stweaks or BLN app. if you have more than one app to configure bln make sure all of them use the same settings.
Q: BLN works in test mode but it doesn't work otherwise.
A: if test mode works you should blame the apps. Stock messaging and email apps may not support BLN and in some other applications you may need to enable notifications. Either find another application or change your ROM.
Q: Can I use breathing effect without using BLN?
A: for now, breathing effect only works in BLN. There is no way of using it otherwise.
Q: I need to disable and re-enable BLN in stweaks to get it working again. What is the problem?
A: You may have another BLN related application (BLNapp, nstools, or a script) which disables BLN after stweaks apply the setting at early boot stage. you have to either uninstall that app or enable BLN in that app as well.

PS: really want to see your new cpu driver....i really understand almost nothing on the new one lol
Wireless & Ad hoc network
Hopefully it will support wireless and ad hoc network connection like the one you created for gingerbread kernel.

I am talking about touchscreen responsiveness same as in CM9 with LP6 kernel.
I slept off on the keyboard waiting. GM can we expect download link soon? Its 5:00am here and I think I need to catch some sleep before going to office... I havent waited for my GF so much.. Damn..
I'll make myself a coffee and test it for 10-20 mins then upload to my blog as first beta...
I finished everything except for BLN. I tried, but could not finish it because of lack of complete cm9 repository in my vm. if anybody can compile liblights, everything else is in the kernel now. If nobody compiles it by then, I will do that in this week, hopefully.
I am surprised with the changes in the platform specific parts. I wasn't expecting that Samsung would make a change in that crap but they did and it looks much better. I have a theory that they outsourced the kernel part (maybe to odroid guys) because some parts look very good which is not something I expect from Samsung softwarewise
anyway. it was a real fun for me. I hope it will be at least as much fun to use it for you.
let the celebrations begin
it's up
and a last minute addition was made for smartassv2 lovers
I guess I take the credit of installing it first.. Installed .. Siyah 3.0b1 CWM . Thanks Golkhan...

yes, I do. but I think samsung used another mali driver in the release. that may cause blank (black) screen. I am not sure if latest CM9 can use LPQ or LP7 kernels but if it can then this beta will support CM9 and most clones.
Hey guys!
So from observations by @rkoby13 and myself, there seems to be a demand for regular builds of DorimanX's kernel!
This thread will serve as a place for logs, reports, and discussion relating to these unofficial builds by me.
Currently the plan is to compile v9 builds, whenever @dorimanx adds major updates or significant modifications to his source, however this may, and probably will, result in UNSTABLE AND EXPERIMENTAL RELEASES
Disclaimer:
Dori tests highly experimental commits prerelease, and if your device is damaged, wiped, or in any way negatively affected by these releases it's not the fault of Dorimanx, or me. In flashing these releases you accept full responsibility for any consequences of its use.
In this op, I'll have a log of which builds are most stable and which ones have bugs reported or major issues in code, and builds with extreme issues will be removed.
As x.39 was just released, the first build will be uploaded after the next major addition to the kernel sources, and every major change after that.
If there is a commit that I have not considered major but is important to you, either reply to the thread or pm me with a link to the commit, and I'll probably update the build to include it. In future, I may also build v8 kernels until their end of life, if many people show a desire for this
Finally, just a reminder not to post logs or reports/discuss these builds in any other thread, thanks
I'll also soon be adding my new and improved stweaks settings guide, nearly everything is covered now.

Eskriminal's New and Improved DorimanX Stweaks Guide!
Starting off, I will not be covering stock standard info such as cpu clock, voltage, or the most basic governor variables. @droidphile has a brilliant comprehensive guide to these things and more, search!
Now let's get started! This guide will be in the same order as stweaks itself, and if i miss anything that you wanted, pm me
Topic 1. Advanced/Custom Cpu Governor variables
Here will be discussed governors such as nightmare, darkness, and perhaps zzmoove (if i have time), and their variables.
Freq_step
this controls how large the step up should be when the cpu load hits either the up_threshold, or the inc_cpu_load, depending on your governor.
It is a percentage, where the percentage involved is that of the cpu clock prior to the switch.
Down_threshold/dec_cpu_load
same as up_threshold or inc_cpu_load, but in the reverse, these dictate at what load to decrease frequency
Cpu_up_rate/cpu_down_rate
these values determine how many readings of cpu load will be collected (i.e. 60% or 80%) before being compared to the inc_cpu_load or dec_cpu_load respectively
Freq_step_dec
the same as freq_step, but for decreasing frequency
Freq_step_dec_at_max_freq
identical to freq_step_dec, but while cpu is at values above freq_for_responsiveness_max
Up_sf_step/Down_sf_step
both have detailed descriptions in app from alucard
<more to come>
Topic 2. Memory Management
This tab in stweaks dictates whether Dorimanx kernel should control the Android memory management system (Auto Oom Control switch)
The settings here control how it should control it, with the more aggressive the setting, the quicker apps will be killed at low memory.
<more to come>
Topic 3. GPU Tab
The GPU settings are all identical in function to the way CPU control works, with the frequency steps available and voltage/threshold changes.
The GPU utilisation timeout controls how fast the gpu should respond to a heavy load.
With the thresholds, as with cpu the higher they are the slower it will scale frequencies up, and the faster it'll scale down.
<more details to come>
Topic 4. Screen Tab
Here all screen settings and brightness controls are changeable.
min_bl controls how fast auto-brightness should increase screen brightness level, when this value is higher the screen will stay on minimum brightness for longer.
min_gamma and max_gamma control the minimum and maximum brightness available to auto-brightness
LCD Power Reduce lowers screen brightness to save battery
Screen colour modes control colour levels
Gamma Shift changes all brightness system-wide up or down based on the value put in
FB early suspend delay controls delay after sleep should activate before running the screen off animation
Vibration force controls the power of vibrations system-wide
Slide2Wake toggles waking the device by swiping across the screen from left to right
mDNIe Negative Toggle enables or disables inverting colours by pressing the home button the number of times set below
Touch screen tweaks control sensitivity options - They're advanced, and usually don't need to be touched
Topic 5. Sound Tab
Most settings are self-explanatory, if anyone wants this actually explained, shoot me a pm.
Topic 6. Big Collection, all Misc. Kernel settings! (BLN, CRON, Logger, Auto wifi etc.)
BLN controls whether to switch on backlights when notifications are received during phone sleep.
The bln effect controls the light mode of these keys (doesn't work with BLN without wakelock)
Notification timeout controls the maximum length of time the keys should be on before turning off (doesn't work with BLN without wakelock)
LED timeout controls the timeout on backlight keys during phone use
BLNWW sets BLN to run without forcing the cpu to stay out of deep sleep, saving battery
LED fadeout controls the effect when the keys switch off
LED on touch determines whether the keys will turn on when pressed during use
LED voltage level controls the key brightness
CRON is a timed automatic service which can be used to run various optimisations and updates as detailed in the 'Other' tab in Stweaks
Fix Permissions may solve fcs in apps
Zipaligning apps may optimise them to run faster
Database optimising will clear and compact the system data, potentially increasing system performance
GPS zone changes to your local ntp server may decrease gps lock times and increase accuracy
USB settings control the device storage mount mode.
Charge current levels control speed of charging from various sources, with the higher the current, the faster the flow and therefore charge
Resetting the fuel guage chip may solve issues when battery appears to drop after reboots, as the chip will recalibrate
The Ad-blocker will block advertisements by ip in most apps
Filesystem tools attempt to recover corrupt partitions on the disk
Root settings control device root security
Cortexbrain controls the switching between various things based on screen state including cpu governor and clock, io scheduler, auto wifi, auto data, and logger control
The android logger writes logs of system errors, disable unless you plan on using this
auto data disables mobile data when the screen is off, with the delay before doing so below it (auto wifi is the same for wireless internet)
Various tweaks change system values relevant to each one
Eco tweaks modifies hotplugging logic when battery drops below the eco-level threshold to save battery by preferring use of only a single cpu core
This is just a preliminary guide, my corrupted hdd destroyed the other one I'd been writing for @rkoby13
Reserve one more! Just in case!

I bought an optimus g for wife, but started to play with it, lock bootloader, hard to root, no custom kernel for oc. It's nice to see that s2 community it's still active.
Regarding domain, maybe ApriliaM3 from neatrom thread, he has an huge one with mods, kernels, rom.

I have a question. What is a "V8" kernel and if its good stuff, why isn't included in Dorimanx official build? I'm assuming because of possible bugs?

maybe you lost track....but dorimanx kernel has 2 branches....8.xx & 9.xx....
8.xx has support for Samsung stock JB roms...aswel as aosp/aokp/cm....<---4.2.2 and bellow...to 4.1.2...
9.xx branch supports 4.2.2 and 4.3 only...aokp/cm/aosp roms and dualboot between them....and with 9.xx you have more ram avaliable ....other things you can find in original dorimanx kernel thread....
v8, for official roms. v9, custom roms.
Dorimanx put sources in git daily and build his kernel. Anyone who could and want, take his sources and make an kernel, based on his sources. So, that's what we are here on this thread, we wait to grab and test an custom kernel

dude! I totally lost my mind. Lol. I totally got confused, I know there is a version 8 of the kernel. I was thinking that this was like the "V6 Supercharger" mod that some people use. I thought there was a new version or something that was kernel based. Hahaha. Thanks for clearing that up for me bud.

ALL THANKS AND CREDITS GO TO THE ONE AND ONLY KTOONSEZ FOR THIS AWESOME KERNEL AND GIVING ME THE OPPORTUNITY TO PROVIDE THESE BUILDS.
Welcome!
I am in no way affiliated with Ktoonsez or his work. I’m just a simple member of the XDA community who happens to be a huge supporter of this kernel and its creator. This is just my way of giving back. I am aware of some of the issues that may occur on specific kernel builds for some users as well as the difficulties faced when fine tuning the kernel and this is my response to that:
This is by no means intended to replace any of the original KT-SGS5 kernel threads. The purpose of this thread is simply to work in conjunction with them by providing a variety of builds for which users can experiment with and see which versions perform as intended on each of their respective device models. As on previous Samsung devices I am also bringing back the Ktweaker Shop filled with tons of pre-configured settings compiled by myself and others in attempt to further assist S5 users with improving their overall experiences on this device or to simply use as a baseline to work upon tweaking further. So I’ve gathered just about all of the current and previous kernel builds I had hidden within my pc as well as all the various Ktweaker settings and am sharing them with the public. I hope this makes a difference for all you guys. ENJOY!! :good:

If at any given time you aren't already on the kernel and Ktoonsez hasn't updated his links, there'll be no need to flash previous builds when you want to receive OTA's as ALL posts will be updated regularly upon future releases. So please be sure to refer back here for all builds from this point moving forward!
I will NOT be held liable for anything that may occur to your device nor will Ktoonsez. So please...
***FLASH AT YOUR OWN RISK***
If you encounter any suspicious issues when updating the kernel, follow my recommended procedure for the best possible results:
1) Backup current Ktweaker settings
2) Open any root browser (make sure it's mounted as r/w) then navigate to /system/app/ and delete the Ktweaker and KTmoniter apk's
3) Navigate to your sdcard and delete the Ktweaker folder OR rename it by adding a ".bak" extension without the quotes.
4) {Optional} Clear all Superuser logs
5) Reboot Recovery
6) Flash kernel
7) Reboot
8) Copy any saved profiles back into /sdcard/Ktweaker/Profiles/
9) Restore Ktweaker settings
10) Profit?
NOTE: If at any point Ktoonsez no longer wants this thread open it will be closed without question.

Welcome to the Ktweaker Shop!
Here you will find all of the pre-configured settings provided by myself and some of our fellow users. As a proud member of Team Kernelizers, I am offering a variety of profiles specifically for S5 users with their personal needs in mind as it's pretty clear no everyone favors the same governor, scheduler, etc.. Any suggestions are always welcome. All future settings will be added here for sharing and discussing our settings as well as gaining approval on a profile to be added into the built-in Shop in Ktweaker. Keep in mind that results will always vary per device regardless on the settings being used.
All profiles have been grouped into 3 sub-categories; "Conservative", "Balanced", and "Performance", which are used to classify each profile based on their overall performance and what they are expected to deliver to your device. The 4th sub-group is where you can find some of our best "Projects" in which offers 2 or more profiles for each. Make your selections based on your usage and apply what works best for you and your phone. We're here to help eachother out and with more options comes better experiences for everyone running this kernel. Big thanks to ALL who have contributed!
So shop around.. pick and choose.. load and go!!
Installation
Download links will include the specified profile(s) as well as an "Adjustments" and "About" file. The "Adjustments" file is just a simplified view of all the changes made to a profile compared to stock settings.
1. Download the file(s) to your phone.
2. Copy ONLY the XML(s) (DO NOT copy the "Adjustments" or "About" file) to "/sdcard/KTweaker/Profiles" using a file Manager of your choice.
3. Open the Ktweaker app and click on the "Profiles" setting at the top of the slider drawer OR scroll to the bottom and select "Profiles & Scripts" then click "Restore Profile from sdcard".
4. The file you just copied should be listed there. Select the one you want to apply and confirm.
5. Make sure the "Set options on boot" setting at the top of the slider drawer shows a little green boot icon below it, indicating the settings will be applied upon reboot.
6. Profit!
Conservative
Asking Alexandria
This is a battery driven profile in which focuses on saving as much juice as possible while also maintaining stability and providing an extremely snappy feel to your phone. It is quite possibly one of the smoothest and snappiest battery saving profiles available.
Why Asking Alexandria?
It's named after yet another one of my top favorite metalcore bands and I chose this because Alexander The Great basically ruled the world at one point and "Alexandria" is the female equivalent to that name, which has become known to mean the "one who comes to save warriors".
"Asking" was an addition to the title name as an indication in the sense that we are all asking Alexandria what she can really do to our phone.
https://copy.com/X8tAZauB2Nw7DDmF
Bless The Child
Based on Ktoonservateq and aimed towards battery. This is specifically for all the battery hungry users out there wanting to conserve as much power as possible. So don't expect the BEST but rather decent performance out of this one.
https://copy.com/DnyKoDtbGzFeBhKj
Dead By April v3 (updated: 5~7~15}
This profile attempts to bring some of the best battery life possible to your device. It is similar to Bless The Child but takes things a step further . It now focuses more on snappiness but still maintains it's well known battery conservation. It manages to maintain a smooth ui for your average daily use.
https://copy.com/YbVh8fJui0Wg
Balanced
Balanced Bull v4 (updated: 5~7~15}
These settings are very special to me as they were my very first, dating back to the Galaxy S3, and is a profile designed for my own personal usage pattern. It has become notable for it's fairly smooth interface and amazing battery life. If this stacks up to your standards then I encourage you to use it!
https://copy.com/XaUC96AHpYd0
ECLIPSE v3 (updated: 5~7~15}
This is a performance oriented option where great battery life is also expected to intervene. This not only will bring an incredibly stable, smooth, and snappy feel to your device but will also benefit towards longer lasting battery so you can love and enjoy your phone the way you were meant to.
https://copy.com/YolJstsJPAFb
Ktoonsified v4 (updated: 3~25~15}
This profile was put together by none other than the BOSS himself, @ktoonsez! This is a performance oriented option in which also offers a great deal of battery life. Haven't tried these settings yet? then what are you waiting for!! Load em up and be prepared for one of the smoothest and snappiest experiences ever!
https://copy.com/VPykcXYipZea
Ktoonsified {MOD}
This profile is intended to work as an alternative to the original Ktoonsified profile. It was modified to slightly boost performance and is specifically for the users experiencing issues on Ktoonsified such as screen wake and incoming call delays, media stutters, or 3D frame drops. Use this profile to repair most if not all your issues and expect an even faster and smoother UI.
NOTE: The adjustments text file will show you the changes I've made from the original Ktoonsified profile.
https://copy.com/JgW2M2wjkmat
SmoothManic v2 (updated: 7~16~14}
This profile was put together by none other than the BOSS himself, @ktoonsez!
The idea with this is to get the CPU really high on 2 cores when screen is touched and then bring them both back down really quick so UI is super smooth but don't kill the battery by hanging out at that high Mhz step.
Click to expand...
Click to collapse
https://copy.com/G7m7dWYh9u6j
SmoothManic {MOD}
Smoothmanic v2 was slightly modified in order to bring the profile up to speed with the most recent kernel changes. It should provide a slight boost in performance but continues to follow a similar scaling mechanism as the original.
NOTE: The adjustments file will show you the changes I've made from the original profile.
https://copy.com/1hHIF7rtw1Rcqwz4
Undisputed 3 (updated: 5~7~15}
This is a universal performance setup in which combines the essential elements of other profiles by providing equal battery life, speed, performance, and stability to bring the ultimate experience to your device.
https://copy.com/nuMTnp4wkQpW
Performance
Feed The Machine v3 (updated: 5~7~15}
The exact opposite of Bless the Child. This is a performance oriented option for all hardcore users. If battery isn't a priority for you then this is a great option.
https://copy.com/FFvQ3DRRUbu1iedM
From Ashes To New
This is a straight performance profile. It's similar to Feed The Machine and Rebirthing in the sense that it syncs the cores to the boosted frequency on touch and almost instantaneously jumps right back down to 300MHz. The difference between the profiles is that this one makes better use of all the cores. However, due to the rapid scale down I think most people will find battery life to be surprisingly good for this type of profile
https://copy.com/WQRuc72k8Faarx4j
KTGaming v2
This profile was put together by none other than the BOSS himself, @ktoonsez! This is a super performance oriented option which allows me to play any game with ZERO LAG!!!!!!!
Click to expand...
Click to collapse
https://copy.com/q7URWZu7qnzV
SmoothGaming
This profile is based on the SmoothManiac MOD but with performance enhancenents to provide a much smoother gaming experience. These enhancements include a much higher sampling interval as well as offline blocks to allow frequencies to scale and hotplug at a more reasonable pace.
https://copy.com/qeqe7fw9o0Xs0gxw
Projects
Comatose
This project was inspired by the album of the same name by my #1 favorite rock band of all time, Skillet. It consists of 3 profiles of which are also named after 3 of my favorite tracks from this album (included in the "Extras" folder) and all focus on one key element; VARIETY.
As the name suggests, "Comatose" is geared towards battery conservation. It focuses on keeping CPU low for a prolonged period but utilizes 3 of the 4 cores on touch and the 4th on demand for fluidity. Sample rates have been decreased heavily as to increase polling and allow the other cores to quickly spike towards higher frequencies for a given task then immediately drop back down as if the component had been knocked unconscious.
The second profile is "Rebirthing". This profile will counteract the affects of Comatose by heavily boosting performance as a means to bring life and energy back into this profile that remains unconscious. Rebirthing is intended for those seeking a performance-based version of Comatose but who knows... For such a power hungry profile you may just be surprised by the great battery life it also delivers.
Some of you may not favor the heavy battery conservation that "Comatose" offers or the overall power consumption of "Rebirthing" and much prefer a mashup of elements delivered between the 2 and that is the purpose of "Whispers In the Dark". This profile is directed towards finding the right balance between these 2 profiles while still acting as a it's own profile. It utilizes most of the performance aspects from "Rebirthing" Like "Comatose" it uses a fairly high up_threshold for that extra boost in battery performance. The profile also idles at the same minimum cpu as "Comatose" but ALL profiles run at stock 2457Mhz.
All profiles maintain the same concept of rapid cpu polling. So yes, cpu will be working consistently but my theory here is that more polling will allow the kernel to rapidly check CPU usage, thus allowing CPU to change more frequently according to the load, which in turn will prevent persistent pegging of even higher frequencies and instead consume various amounts of power in various scenarios depending on your usage, consuming even less when a specific task has completed and immediately dropping the load.
This also applies to screen off states but that goes back to what was explained in this post regarding high vs low sampling rates and how they can greatly increase idle times depending on your screen off max.
https://copy.com/wzq0Edm2xueOxZJd
If you'd like to contribute to the Ktweaker Shop all you need to do is post the profile you'd like to share and include a brief description of it's purpose. It will then be tested thoroughly by the community and based on feedback will be submitted here in the Shop for approval and sent out to the dev so he can add the profile to the Shop in Ktweaker!

Wiping caches before flashing should have the same result as wiping after. It's just what KT recommends. I also have never had issues wiping beforehand.
As far as the typo goes, I copied and pasted that post from my S4 Thread and haven't completed my edits yet lol.
I was just busting your ballz about the s4 > s5 typo. I figured as much. Hehe.
Anyways, thanks for the explanation on wiping cache / dalvic.
I haven't had any issue in doing it before or after either, just wanted it to be clear.

Anyone using dead by april? Just wondering how much better battery life it gets you. I've been running it for a couple days and I'm seeing a bit worse battery than stock.

Depends on how you use it. The profile is intended for conserving battery by undervolting the CPU and throttling it. If you have cpu intense apps that require phone awake all the time, the results won't be great. In that case its not a profile for your usage pattern.

Back up just the boot partition in twrp. Then restore it.
I think that's what you mean. Correct me I'm wrong.

Hi all,
some of you know me from the Samsung devices area, where I provide my kernels already for more than two years to Galaxy S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.).
Maybe you also know me from my OnePlus One kernels I added in winter last year to my portfolio.
Finally I got a Samsung Galaxy S5 afew weeks ago and decided to port my kernel also to this device. This is a sponsored device, so I want to say a big thank you to the people that made it possible, namely the ones in the German Smartphone Forum www.hubo.in !!!
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other, good existing kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
For the CM Boeffla-Kernel, please go HERE.
Important notes
When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
Compatibility
Important: This kernel is only meant to be compatible with official Samsung stock firmware and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app.
Click here to learn about using the config app.
I will refuse to give support if you do any undervolting and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.

Based on latest Samsung sources
Kernel runs with SELinux enforcing by default, just as Samsung stock kernel for S5 - but can be configured to work in permissive mode in Boeffla-Config settings
Knox and Samsung rom security warnings removed
Note: I do NOT upstream the kernel to higher Linux kernel versions anymore as this usually has zero benefit but likely introduces new issues + is a waste of effort in the end

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the Galaxy S5 kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
f2fs - it is known to cause various issues and compatibility problems
a CAF based kernel
anykernel method to use the ramdisk of the installed rom
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the correct kernel depending on whether you are on Samsung Stock, CM12 or CM11 !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.
You need at least version 2.1.72 or higher for the Galaxy S5 Boeffla Kernels.
Donation
If you like my work, feel free to donate: Donation-Link
If you donate at least 2,49 EUR (to be in line with the donation app prices on Google Play store), you will receive a personal donation code which unlocks some nice little comfort functions in Boeffla-Config V2 on top.
Source code
All sources can be found in my Github repository: http://github.com/andip71
Credits to developers
Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:
* ZaneZam
* Yank555
* ktoonsez
* Hardcore
* Chainfire
* AndreiLux
* Netarchy
* Gokhanmoral
* Entropy512
* Faux
* Ak
... I just hope I did not forget someone. If so, please let me know and I will add you of course.
Thanks to all of you for your great work !!!
Disclaimer
*** As always - Flash on our own risk! ***
Make sure you flash the correct version depending on your firmware version!
I can and will not take any responsibility for bricked phones or lost data.
It is generally recommended to run a complete Nandroid backup in your custom recovery and safely store your personal data before you flash a new kernel.
Cheers and enjoy

*** You want my support? Then stick to my rules ***
Guys, I am receiving more and more completely useless support requests in different threads. Useless because people provide nothing to be able to help, not even the minimal possible information they could give.
Hence, I will now remind anyone again on the support guide lines stated here:
http://boeffla.de/index.php/support/support
Also you need to ensure you follow the installation guide lines incl. trouble-shooting stated here:
http://boeffla.de/index.php/support/installation-how-to
And to cut a long story short: If you do not at least provide what I request in the support guide lines, I will IGNORE YOUR REQUESTS IN FUTURE.
Straight and simple. I have enough of people wasting my time just because they are too lazy to write details.
Period.
Also as a reminder:
you use xposed? -> no support, everything is your own issue
you use a custom rom and not the official stock or CM one? -> good luck, you are on your own
you undervolt or overclock? -> have fun, but without my support
Sorry, this might sound harsh (and it is meant to sound harsh), but you cannot imagine about how crappy support requests can be. Stating something does not work is just not enough.
Please consider that!!!
Andi
yeahh, dr andi so glad to see you here ..
You can also submit g900h variant? I can a beta tester

I am sorry, nothing changed in my attitude and golden rules over the past years.
No device, no kernel.
Apart from that, I need to stop adding new kernels now, it just gets too many already. And once I realize quality does drop, I have to stop.
Andi
Thank you,Andi
Thanks to @Lord Boeffla, finally today you've released your awesome kernel. Of course I saw @ZaneZam thanks to you too and I know we might have another version will be compiled and supported. Nice
Hi all,
Great kernel
Works very fine
Check this out...
Thanxxxx to the Lord for the hard work in the last week's
It's hard to access root rights on my device with Stock Deodexed Prerooted Rom. I've flashed Update-SuperSu 2.46 in TWRP, but RootChecker checked with no Root installed on device

Not a problem with Samsung Stock BOB7 firmware.

Hey Lord,
thanks for your awesome work! I really liked your kernel for the S3, even better you're now developing for the S5.
Immer weiter so men Jung!

We need you guys to find that out, the S5 is not my daily-usage phone. So all I get is quite hypotethical at the moment.
Andi
Andi, forgive me, does it work on ANG7?
Never mind, Lollipop upwards
Looks good so far on XtreStoLite!
I'm just wondering if you are planing to add full sound configuration options?
Your sound implementation options allowed superb sound on S3 and I guess I'm not the only one missing it on S5
Looking forward to next versions!

See OP, first line. Clear "maybe"... I tested against BOB7 only as I cannot install 10 different roms. But you will tell us?

Would love to. But it is a completely different sound chip used in the S5, compared to the S3.
And it seems there is no way to get hold of any documentation for it (wdc9230), which would allow us dev to explore more of the chips capabilities.
If you saw a kernel providing more sound options, I am happy to get the information about it and checking if it can be ported. Then we would even know what the audio hub can do and what not...
Or someone can get Qualcomm to hand me over the documentation of their audio hub, then also more is possible. But many devs for sure have tried that in the past years already, so I am not very optimistic.
Andi
Battery friendly seems so good for daily usage at the moment, but Battery Saving with zzmoove / battery yank seems pretty lags. Hope it be implemented some next versions.

Yes, it lags. And it is a hardly battery focussed preset, so it must lag.
That is why you have the choice.
