This is a list of custom kernels, not ROMs and there are kernels that aren't listed here yet (either new kernels or newer versions), so be patient - I'll try to update ASAP (or when I feel like it )
It is meant for people who want's to find out what kind of different kernels there are in XDA forums and then users are able download/install kernel that he/she wants to try out.
This is not about comparison of kernels (but you can vote the best kernel), just a simple list of links to kernels and some basic info about those - so users don't need to search the whole 'Galaxy S I9000 Android Development' thread to find suitable kernel.
Thanks for feedback and updates. You can write a reply or send PM if you see new kernels lying around (that are not listed here) or just if you have any questions or so...
NOTE: Me or kernel developers are not responsible any problems caused by installed kernels. By flashing your SGS (or even installing su?) might void warranty.
Before flashing check that your phone can go to download mode.

Some important information about the listed items.
The information about listed kernels are stripped due to size limitation of single message and therefore I couldn't include all posible information about each kernels.
Remember to check peroidically this list of kernels from their threads for possible updates (once a day/week/month).
These are Gingerbead kernels. List of Froyo kernels are here
http://forum.xda-developers.com/showpost.php?p=13509694&postcount=23
The reason for splitting list to two messages is the limit on one message size.
Remember that some kernels have both Froyo and Gingerbread versions (and some even eiclar), for example [16.04.2011][CF-Root 3.1] JP*,JS*,JQ3,JV1/K/B - su+bb+2e/CWM - rfs+ext4
and that's why it is listed in both lists
Please notify me (pm or whatever) if I have made a mistake and some item should be in other list or both lists.

Thread: http://forum.xda-developers.com/showthread.php?t=788108
This rooted kernel is for the "rooting beginners" and those who want to keep as close to stock as possible. CF-Root takes the kernel from an original Samsung firmware, and just adds root, busybox, unprotected recovery, and CWM compatibility.
If you are looking for highly optimized kernels or kernels that perform specific functions, look elsewhere. All CF-Root's are based on original Samsung kernels, they are NOT recompiled, and thus ensure maximum compatibility.
THIS IS NOT A ROM - it is only a kernel. You need to have a firmware already on your device. You do NOT need to wipe anything for this patch. You DO need to read the instructions.
MAKE SURE YOUR PHONE CAN ENTER DOWNLOAD MODE USING THE KEYCOMBINATION WHILE BOOTING BEFORE FLASHING CF-ROOT (or anything, really)
Donate
There have now been over 200.000 downloads of CF-Root and many more if you include ROMs, kernels, ect that use it. Don't be a leech, buy me a beer (and use the "Thanks" button!)
Features
- The kernel is fully stock and taken from the original firmware, with just the following added:
- Root
- Superuser 2.3.6.1
FROYO ( CF-Root < 2.4 versions )
---- Busybox 1.15.3 or 1.17.1 (if not mentioned in the filename it is 1.15.3)
---- "2e" recovery (can flash unsigned update.zip's)
---- Integrated fix for ClockworkMod's nandroid (2.5.0.4+)
GINGERBREAD ( CF-Root >= 2.4 versions, JVK and newer )
---- Busybox v1.16.2androidminimal (from CWM)
---- Integrated CWM 3.0.0.5 / RFS

Another Sticky material. I hope you keep updating this list for it to remain stickied.
I have rated this thread with 5 stars.
PS : You could actually make sections for 2.1, 2.2, 2.2.1. For example, there are some old 2.1 kernels lying out there that can be helpful to some users. Maybe you can include lagfixes like OCLF with warnings on when & when NOT to use it.

Thanks for feedback. I added voting.
Have been a hardcore fan of hardcore's SpeedMOD kernel But as of late, I've been experimenting a bit and now I'm torn between DamianGTO's Ultimate kernel and FuguMOD!
First advanced voodoo, then speedmod, and now on tegraks. Completely different from the rest, unique.

Best to ask in Darky's thread.
Also all information should be there in the OP. Or ask in the thread of the kernel creator.
If Darky has CWM or 2e recovery, then you should be able to flash as per normal.

@K4P1: maybe you want to include these in your first post.
Tools/Methods for flashing a kernel:
SGS kernel flasher (android app) by me - requires root
Heimdall - Open-Source Cross-Platform Flashing Suite (Linux, MacOS, Windows) by Benjamin Dobell
Flash Firmware and kernels using Odin (post in the FAQ by Darkstriker)
This list is sorted by the required level of skill in usage and by the easiness to break the phone with the particular tool/method...
And these are threads with videos that show how to use these tools:

Thank you !! :good:
Basic kernel description:
this is a Gingerbread LG O2X Stock kernel! not for use with Cyanogenmod
focus on stability, smoothness and great power consumption
Linux 2.6.32.9
allows Ramhack from 0-96 MByte (this means 0-96 MB additional real RAM, lowering GPU Ram), can be set easily with GuesteOC app, reboots aren't affected by ramhack.
comes with TrymHansen's famous GuesteOC app - following kernel-features can currently be controlled with it:
stepless or stepful over- and underclocking from 216 MHz - 1450 MHz
complete deactivation of second cpu core (and reactivation of course)
setting of maximum screen-off frequency
second cpu core activation speeds/times and auto-calculation of those
change of IO schedulers and read-ahead buffer
swappiness
2-way virtual RAM enhancement: you can choose between Swap & ZRam and enable/disable them on the fly
disable fsync (can be used for higher benchmarks) - attention, disabling is bad for your data in case of sudden power loss and also it can both decrease or increase power consumption
touch-light brightness (101 intensity steps choosable)
special feature: changing auto-backlight intensity (8 intensity steps choosable)
on-the-fly changing of virtual RAM size (16 - 256 MByte)
slider for vibration intensity (from very low to strong)
changing Ramhack-Size directly from within GuesteOC with a slider - 0-96 MB; modifying boot image and reboot happens automatically on applying
app for Undervolting included (MyrtUV by TrymHansen)
Default CPU speed is 1000 MHz - but you can OC using the included app of course
OnTheFly-changing of kernel logging policy:
Code:
kernel_logging
(OTF name)
It accepts values 0, 1 or 2
0 = no logging [GuesteOC-default, set on boot after kernel flash]
1 = logging only when screen is on
2 = logging all the time [kernel-internal default, used until overwritten by GuesteOC]
This can be controlled/set via GuesteOC app.
[Kernel logging is what you see when you open the app "aLogcat"]
less or no logging is believed to save some battery juice
merged/included FORCE_FAST_CHARGE - credits to chad0989
...
For this kernel + the GuesteOC app to work properly you need init.d scripts to be working on your ROM. You should be able to enable them using the latest AROMA installer of guestekrnL >= v2.1, if they are not working on your ROM.The toolchain affects: stability, smoothness, performance & power consumption.If you can't enable ZRam, upgrade to Rebuild 2 release of guestekrnL v2.0 or to a newer releaseIf something else doesn't work: Recommended is Busybox 1.19.4 -- install it with JRummy installer, not a different installer!@ROM-CHEFs (important!):
If you want to directly include guestekrnL v2.x in your Stock ROMs, you will have to set the command line parameters of your ROMs boot.img (via Android kitchen -> modify boot image -> modify command line params) to the following (otherwise Ramhack can't be enabled by the users):
Code:
[email protected] [email protected] loglevel=0 muic_state=1 lpj=9994240 CRC=3000001a323ed07 vmalloc=256M brdrev=1.0 video=tegrafb console=ttyS0,115200n8 usbcore.old_scheme_first=1 tegraboot=sdmmc tegrapart=recovery:35e00:2800:800,linux:34700:1000:800,mbr:400:200:800,system:600:2bc00:800,cache:2c200:8000:800,misc:34200:400:800,userdata:38700:c0000:800
(This will enable the default 32 MB RamHack right after the installation of your ROM with latest guestekrnL included.)
Also in v2.0 the setup script and many setup files of guestekrnL have changed - make sure to merge all the important parts into your ROM setup. Also do not include boot-up scripts which modify LED brightness or virtual RAM and similar stuff or disable kernel logging because that's the job of GuesteOC app.
Changelog latest version:
v2.2.1
smoothness-related changes for higher smoothness
tun.ko now built-in in kernel again
spica toolchain edition now is default preselected on in AROMA installer
v2.2
smoothness-related changes for higher smoothness
better RAM management
tun.ko now as kernel module instead of built-in in kernel
dropped symbi0sis-toolchain edition, instead added spica1234 toolchain edition (like the name says this toolchain has been built by spica1234, credits for this chain go to him)
new unique feature: introducing dual-vibrator support:
in GuesteOC you can set the kernel's vibration intensity (like you already know)
new: intensity 1500 - 2700 uses "weak" vibrator output device for vibration (the one used in original stock kernel)
intensity levels >2700 - 3700 use the "strong" vibrator output device
some prefer the weak device because it seems to be more "accurate", others prefer the stronger one
now it's completely up to you which one to use, without having to change the kernel version! Enjoy
Changelog version 2.1:
v2.1
also read the v2.0 Changelogs!
smoothness-related changes for higher smoothness
added FlixEdition-Power by and for flix123 with the following differences to official version: https://github.com/StefanGuendhoer/guestekrnL_for_stock_v1.6.2_upwards/compare/master...FlixEdition - the differences are minimal because I merged some good changes into the official version of the kernel. Nevertheless thanks to flix123 for his endless efforts to make this kernel smoother :good::victory: Currently the FlixEdition-Power is only different from guestekrnL-Flix123-Chain in it's default GuesteOC settings (heavy use of second core, different scheduler, stock led brightness,...) and in the default ramhack size. Still flix123 has earned his own edition named after him, as he is the creator of the very smooth flix-toolchain I use for 2 of my builds as well and the one responsible for some more smoothness improvements in the kernel in general.
Still I recommend to use the normal/official build as of the default heavy use of second core of FlixEdition-Power (higher battery drain during use) and because fsync is disabled by default - not everyone likes that.
AROMA Installer is now able to enable init.d, apply smoothness tweaks and convert filesystem to ext4 if a user selects this option - however this option can only be experimental as it replaces the boot image, which should but might not work fine on every stock ROM. Backup first!
Changelog version 2.0 part 3/3:
v2.0 Rebuild 2
this kernel version is still the same as v2.0, so also read the other v2.0 Changelogs!
fixed ZRam not working for everyone - see the changes here: https://github.com/StefanGuendhoer/...mmit/55eac20be15cffe001c5d2ce9452f3887e7fff74
This rebuild has been made for all those who had problems enabling ZRam
Who already got ZRam working and already has latest GuesteOC v2.3, does NOT need to upgrade to this release!
Changelog version 2.0 part 2/3:
v2.0 Rebuild 1
this kernel version is basically the same as v2.0 so please read the changelog of v2.0 additionally!
introducing 2 new editions (built with a toolchain by flix123) for provision of maximum smoothness + an extra AROMA version with ALL kernel editions inside:

new GuesteOC v2.3 directly included with undervolting AND overvolting (new) - TrymHansen is the creator of guesteOC, thank you very much for this awesome new version, Trym! :good:
complete sources of guestekrnL v2.0 will be published soon - this means the Ramhack for stock, vibration strength for Stock, tweakable kernel logging and other features introduced by me for guestekrnL will be available for other developers too - please don't forget who introduced them first.
Advice:
Please try the new edition(s) compiled with flix123 toolchain (by flix123, thanks to flix for provision!) - you can test & install them along with your preferred settings with the cool new AROMA installer package!
Changelog version 2.0 part 1/3:
v2.0
introducing ramhack + changeable ramhack size (!) (details some lines below) - never seen on any LG O2X stock kernel before
introducing completely adjustable vibration intensity (!) (details some lines below) - never seen on any LG O2X stock kernel before
additional UHOC (ulta high OC) version is available too with default clock of 1,1 GHz and max clock 1,536 GHz - the frequency/voltage table looks like this:
<=216 MHz - 770 mV \ <=389 MHz - 770 mV \ <=503 MHz - 800 mV \ <=760 MHz - 875 mV \ <=912 MHz - 925 mV \ <=1150 MHz - 1025 mV \ <=1312 MHz - 1125 mV \ <=1408 MHz - 1225 mV \ <=1536 MHz - 1325 mV

(9 steps because symbi0sis offers one faked additional freq/volt step unlike other kernels)
only use UHOC version if you really need overclocking > 1,45 GHz! otherwise use default version (HOC) with OC up to 1,45 GHz
new symbi0sis toolchain v2 with full arm hard-float ABI support instead of softfp, updated components and tweaks
4 kernel versions:
Which version of the kernel should I take?
only take a version with "-UHOC" at the end of the filename if you really need highest overclocking
symbi0sis toolchain is always changing and work in progress. its purpose is to beat guestekrnL toolchain in kernel smoothness, performance and battery.

hmm which version to choose? guestekrnL tool chain or symbiosis tool chain? what is the difference?

As mentioned the compilation toolchains are used for compiling the kernel under linux (= making binary kernel image out of kernel source files) and affect battery, stability, smoothness (scrolling) and performance of the kernel.
guestekrnL chain is from May 31 2012 (initially created for guestekrnL) while symbi0sis v2 is from October 10 2012. guestekrnL chain is the "good old stable&smooth one" and symbi0sis is the one aiming to beat (be better than) gueste --- war of the chains :laugh:
Some differences:
- symbi0sis chain v2 uses gcc compiler v4.5.4 (2012) while guestekrnL uses gcc v4.5.3 (2011)
- symbi0sis chain v2 uses some newer libs and components than guestekrnL chain
- symbi0sis chain v2 is a full hard-float chain while guestekrnL chain is softfp (probably performance improvement)
- some differences in build flags
- minor other differences
Feedback on the performance of both chains by different users:
- symbi0sis chain v2 seems to provide a bit better power consumption than guestekrnL chain
- symbi0sis chain v2 seems to provide the best overall performance
- guestekrnL chain seems to provide the smoothest slow-scrolling (so the fewest lags when scrolling very slowly)
- guestekrnL chain seems to be a bit more stable than symbi0sis chain (so if you use symbi0sis and have freezes or something you might want to try guestekrnL chain edition)
So just try whatever edition you like, they are both not bad at all.
enhanced kernel building script which automatically builds all 4 versions of the kernel (2 toolchains + UHOC/nonUHOC) - advantage for me basically because it saves time :laugh:
switched back to ZRam without snappy compression due to some lagginess reasons
drastically improved smoothness
various changes in kernel configuration, inspired by 1.1.2 of my CM7 symbi0sis kernel
added full arm hard-float ABI support for performance
there have been some changes in the kernel & GuesteOC default values, so the currently recommended settings will be set in GuesteOC automatically after kernel flash. Try them.
changed auto-brightness steps: the lowest step now is 99% identical to CM7 kernel original default auto-brightness
new build flags for kernel modules
updated GuesteOC app by TrymHansen (thank you!!!) for controlling new kernel feature, supporting new kernel modules structure & mounting and fixing some bugs
tweakable kernel logging (logging disabled by default)
screen-state-based kernel behavior: giving for example the possibility of kernel logging only when screen is on
kernel modules can now be loaded with "modprobe <module-name>" and don't need to be loaded with "insmod <full_module_path/module-name.ko>" - advantage: modprobe doesn't need full module path and also loads dependent modules if there are dependencies
stability improvements
removed Compcache (ZRam is better)
I introduced a completely new kernel OnTheFly feature: (never seen on any LG O2X stock kernel before)
Code:
kernel_logging
(OTF name)
It accepts values 0, 1 or 2
0 = no logging [GuesteOC-default, set on boot after kernel flash]
1 = logging only when screen is on
2 = logging all the time [kernel-internal default, used until overwritten by GuesteOC]
This can be controlled/set via GuesteOC (see screenshot).
[Kernel logging is what you see when you open the app "aLogcat"]
less or no logging is believed to save some battery juice
Amazing new features by TrymHansen for GuesteOC:
on-the-fly changing of virtual RAM size (16 - 256 MByte)
slider for vibration intensity (from very low to strong)
changing Ramhack-Size directly from within GuesteOC with a slider - 0-96 MB; modifying boot image and reboot happens automatically on applying - THX again to TrymHansen, you are the best!
optimized AES and SHA1 routines
current size of Ramhack is OTF readable in /proc/gueste/ramhack_size -> default: 32 MB Ramhack [changebale in GuesteOC]
OTF changeable vibrator (haptic feedback) intensity in /proc/gueste/vibe_intensity (values 1500-3700) [changebale in GuesteOC as well]
enabling optimized crypto routines in defconfig
added 3 small binaries to kernel setup zip for providing GuesteOC app the possibility to change ramhack size
many changes in kernel configuration
battery-related changes
some other, minor things
some tweaks
credits during changes of this release to TrymHansen, morphic, wkpark, vadonka, faux123 and benee - If I forgot someone he/she is most likely mentioned in the git commits or source code merges or the changelogs and commits of my symbi0sis kernel

Questions:
What does virtual memory/RAM mean? Virtual memory means that the real available RAM (the more the bigger Ramhack is) can either be compressed to simulate additional RAM (= ZRAM) or it can be enhanced using a Swap file which will be stored on the SD card. Swap is slower than compressed RAM, and compressed RAM is faster but needs more battery!
I OC'd / UV'd too high and get bootloops - what now? If you OC'd too high and get bootloops, re-flash only the kernel, it will remove OC / UV ! No need to re-flash whole ROM.
Download all versions: http://www.mediafire.com/?9lvnkfthj9dbo
Installation: Just flash. Preferably use a clean system without many left-overs from other kernel so you don't get a wrong impression of symbi0sis kernel.
Stefan Gündhör said:
Hi! Nice to hear that you are willing to try guestekrnL :good:
Well since some version guestekrnL deletes some init scripts and some additional stuff flashed along with other kernels like HorsePower, but there might be some files (left-overs) not being deleted by guestekrnL setup script.
Easiest way would be if guestekrnL cleaned the whole init.d folder, but I always criticized this about kernel DEVs doing this because in this cause all custom init.d scripts added by creators of custom ROMs would be lost too.
However there are some things guestekrnL can't/doesn't clean: Tweaks by other kernels in /system/build.prop file per example. These entries will be left over even if you change your kernel.
You could of course replace this file with the original file of the ROM you use.
Additionally in past some kernels also replaced some system files with tweaked or different ones. You can't really undo that.
But basically this is no problem, the tweaks will work with guestekrnL as well. I just mentioned it because user experience / power consumption / stability of "clean ROM + guestekrnL" versus "ROM with different kernel previously + guestekrnL" might be different.
But just go ahead, try guestekrnL and if you think you need a full wipe you can still do that later on

extremely small kernel and modules sizes (even without -Os compilation flag)
both ZRam (+369 MB Ram) and Swap (+383 MB Ram) enabler/disabler available for download - freedom of choice (ZRam enabler will disable Swap and vice-versa) ; Zram should be more performant than Swap, but eventually also drain the battery faster ; both ZRam and Swap are disabled by default
BFQ scheduler updated
many entries added to global kernel configuration file "include/linux/guestekrnl.h" (only important for users interested in compiling guestekrnL from source)
bug fixes, performance tweaks
compilation flags changed (-O2 instead of -Ofast)
some kernel logging removed
xz-compressed kernel image, xz-(de)compression (boot-time) support added
reverted some changes in lowmemorykiller
many voltage and clock/speed adjustments
new version of ZRam enabler, the old one won't work!
stable, not too highly undervolted kernel -- you can UV yourself using UV tools though (only overclockable edition)
Changelog:
March 03, 2012 -- guestekrnL v1.2.1:
Overclocking bug fixed - once CPU is OC'd it will stay OC'd now
changes in cpu speed steps: new steps are 216, 324, 503, 800, 1015, 1100, 1216, 1408 (same steps as etana kernel currently uses)
kernel default cpu speed now 1.0 GHz like stock kernel

revert second core activation & treshold back to stock kernel settings for better battery
there will be an additional version with stronger vibration soon (thanks and credits to spica!)
currently two downloadable & flashable kernel ZIPs:
guestekrnL_v1.2_FINAL_withAndrevOC_normalVibration.zip -> Andrev OC Adjuster and Myrt Undervolt GUI will be installed directly with the kernel
guestekrnL_v1.2_FINAL_Bulk_normalVibration.zip -> Only the kernel will be installed
-- pending: version with stronger vibration
Changelog:
February 18, 2012 -- FINAL version of v1.1:
new cpu speed steps & voltages
again more smoooothness (scrolling, responsiveness)
max. ScreenOff CPU frequency lowered to 316 MHz and some other changes (hopefully saving some juice)
3 versions of kernel with different cpu speed steps:
Low overclock version with cpu speed steps 216-316-503-655-816-912-1015-1100 (MHz) -- recommended version!!
Medium overclock version with cpu speed steps 216-316-503-655-816-912-1015-1216 (MHz)
High overclock version with cpu speed steps 216-316-503-655-816-912-1015-1312 (MHz)
the first 7 cpu speed steps are the same in all 3 versions, because I decided these steps are the best choice -- there is only one OC step because there can only be 8 CPU steps (handled by OC tools)
try 1,1Ghz max version, it is smooth enough for nearly everyone I hope, even at 1,0 GHz!!
default max cpu clock (screen on) is 1015 MHz

I'll not use this moment, because I use CM7 + vadonka's kernel. But I followed the topic and kernel development, for future testing based on a stock rom. Thanks Stefan.
totally agree with your initial paragraph, personally I envy the knowledge that shows every day spica, but for the ignorant like me, is much more useful to mention kernel set, and while this is a personal opinion, maybe instead so many parameters to configure, it would be more useful, use presets as a function of the tastes of each user, power, response, saving battery etc etc, well, maybe not the right place here, well, in principle, its kernel is installed normally, it may seem silly but I assure you it is not, say my phone is very special in terms of internal modificaiones already the slightest forces blocked at the moment I tried connecting wifi perfect, seamless gPS, fM radio without problems and later proves the bt. As for the rom, I'm wearing the carburano and is perfectly smooth, no lags etc., for the moment .... we know that android is the opposite of wines worsen over time. Best regards, and I hope this is not really your last job for our phone, I say sincerely.
Stefan,
Thank you very much for this kernel, installed without thinking and testing it now. Couple of observation I made, and opinion I have about the testing stuff.
1. I have no experience in android and stand in minus on technical aspects. You opinion about letting users do the testing of kernels is kind of valid BUT since IMHO, what spica doing is the right thing here. Since this is a development section. So technically developers release their work here so that others developers can test it and contribute 'technically' to improve their work. Honestly speaking dumbass users like me have absolutely no place here .
Everyone who uses the work of a developer have to , should and must understand that what he is doing is testing a possible experimental work and it can lead to unpredictable results. Then analyze what happens, look for possible workaround or solution and give it back to the developer and others, to improve his work.
Dumb users like me have no place here because I don't understand what happens if I use a particular switch or parameter. So there is absolutely no point doing something that I have no clue and then come whining and spoil the developers thread with statements like "helppppppp or my phone is deadddd " or similar things, without even bothering to give details like - for example - what kernel they use, what BB / ROM combination they have, What other application they installed that possibly can create this problem.
Having said that, there are a lot of good developers who patiently help people like this because of the goodness of their heart - you are on of such person. Yet, this being a developer's section should not be treated by noobs as a personal helpdesk to get instant technical support for FREE. If that happens, it affect the development very badly because it wastes everyone's time - especially of the developers.
Phew..! Since my rant is over, I will get back to you 'if' I understand what happens after installing your kernel and eagerly waiting for your latest gift to us .
Congrets for new kernel, nice to see you back
No offence, I don't like even to write this, first time in my life I'm writing this.
OP:
It's not only the instability of current kernels, it's also the "overkill" especially spica does with his latest RC12 kernel - I prefer to keep things simple, users are users and not developers, and so I don't really like this "outsourcing" of sensitive kernel settings to users. There are various good CM7 kernels and they don't need this stuff either. Also spica compiles his kernels with the O3 optimisation flag instead of the usual O2 flag. O3 means even higher code optimisation, but so high that it can easily result in broken kernels or weird issues and bugs. Almost nobody uses O3 flag for kernel compilation. So I tried to create a stable, performant and hopefully not too much battery-consuming kernel myself. The sources of ironkrnL and Swiftextreme kernel (both CM7 kernels) have been very inspiring and helpful.
==>" it's also the "overkill" especially spica does with his latest RC12 kernel - I prefer to keep things simple, users are users and not developers "
What I do is something you can't, that's why want to keep it simple What I do is something *new* which needs more skills, knowledge of HW and programming Yes users are user not Devs, That's why I've set simple 'Powersave" and 'Nitros' profile for them who have no more knowledge. And we've an APP now to control these values
==>" and so I don't really like this "outsourcing" of sensitive kernel settings to users"
SENSITIVE? None of my max values are above your or any other Kernel's max values. I've given an opportunity to lower the values not increase the value. And my default values are lower than your or anyother kernel So in terms of SENSITIVE, atleast RC12 values are not sensitive, And I've written kernel modules to not accept any SENSITIVE values,You don't like thiis "outsourcing" values. What you like applying various pre-available *patches* which berely are made for android? Or you dislike someone's coding knowledge?
==> " There are various good CM7 kernels and they don't need this stuff either"
Nobody needs nothing as per your psychology. And as per your psychology CM Devs should have abandoned development after they had released first stable version. As per your psychology they should have stopped adding new features and releasing nighties and RCs? What can we say in other words? "End Of Development?" Nothing is needed until it's valued. Do you know what SR and RC means? PPL who wants stability can stick with SR series. CM7 kernel don't need this stuff cause they've more important other things to concentrate on
==>"Also spica compiles his kernels with the O3 optimisation flag instead of the usual O2 flag. O3 means even higher code optimisation, but so high that it can easily result in broken kernels or weird issues and bugs. Almost nobody uses O3 flag for kernel compilation"
Where you learn this? Yes nobody uses O3 but Ofast which is 2 steps more optimized flags. Swiftextreme uses Ofast and many devs use Ofast. So as per your theory does these kernels are resulted broken kernels with bugs and issues?
Then I think you should e-mail GCC to remove this O3 flag
==>"So I tried to create a stable, performant and hopefully not too much battery-consuming kernel myself"
Your kernel obviously should be stable cause You've done nothing creative. What do you think is resposible for stability? You used LG base source, merged Oc and Voodoo codes and other codes available. So definately it should be stable. But is that stability is credit of yours or LG and other Devs? There is a way much difference in compiling kernel and developing kernel. Anybody can merge changes with basic linux knowledge and issue few commands and kernel is ready. Developer in real mean is someone who creates something out of nothing, who has knowledge of stuff and how stuff work, someone with knowledge of programming to write codes, read and to be understood codes and knowledge to rectify wrong code and correcting them. There is a way much difference in Kernel Compiler and Kernel Developer.
This is no personal, I dont want to hurt anyone but to clear somethings Dont mind
There are some users who prefer simple and stability rather than something with many new features but not so stable.

Yes you're absolutely right but whats the theory and logic of writing that paragraph in OP thread?
Does it make sense?
Sent from my LG-P990 using Tapatalk
the difference between the v20l and the v20q kernel is almost nothing.
better off pick any v20l based OC kernels what is tested by the users already
some people believe that the new v20q kernel is have a new features and better stability. i was compared the v20l and the v20q kernel, an other thread im posting the difference and a patch file too. i can say the lg developers did not force themselves.

Can we stay on topic?? Thanks
Yes that would be bad to close this thread...... for some words that should never have been written....
+1 for spica, critizing a developer for doing something new is not right IMO. if u want stable then stick to stock.
BTW loving the flaming going on ;-)

I do not think anyone has criticized spica, quite the contrary, two different views and equally positive in the absence of our device as usual and once again the LG more interested, however, the thread is to talk Kernel, not if I like something or other but ultimately developers to present their work and the rest to try them. and our opinions to help improve the whole story. Greetings to all.

if u wanna talk about kernels and not personal views about who likes what, then stefan should not have said this line " It's not only the instability of current kernels, it's also the "overkill" especially spica does with his latest RC12 kernel - I prefer to keep things simple, users are users and not developers "
Yes that's what I'm pointing, on the first page(OP) of this thread, he should write describtion about his kernel like what other dev does, not about what I or anyone is doing
Never mind

im +1 for spica because if my english aint so bad this line he said looks like criticism to me " It's not only the instability of current kernels, it's also the "overkill" especially spica does with his latest RC12 kernel - I prefer to keep things simple, users are users and not developers "
for my issue resolved, but absolutely sure that the intention of stefan is not apparently be interpreted, also without a doubt, and now please, to the point, the kernel, and I must say that I tried the BT's car and has not been disconnected at any time, not blackscreen not freezes at least for now the battery issue, I can not say for now.

How to install:--On S-OFF devices--
-Flash the zip via recovery! (twrp or cwm)
-Reboot
--On S-ON devices--
-S-OFF your device, then use above steps!
(Yes, i highly recommend to S-OFF before using any custom made things!)
or
-Extract the boot.img from the .zip.
-Get in fastboot and flash via [highlight]fastboot flash boot boot.img[/highlight].
-Reboot into recovery.
-Flash the zip via recovery.
-Reboot
[highlight]The same thing applies if you update to a higher version or if you downgrade to a lower version of the kernel.[/highlight]
README!- JB Versions recieve OTA updates over Goo Manager!
-Do a nand backup before testing!
-[highlight]Test[/highlight] versions are for testing, therefore expect bugs and please report them in detail.
-Beware that you use this at your own risk and please provide feedback in order to get it stronger/better/bla bla bla
-The versions of kernel for ICS Sense around here should work on all OFFICIAL ICS 2.31.401.2 RUU based roms, and the official one of course, so if you use a different firmware, make sure you make a backup as there are BIG chances it will not work.
-The versions of kernel for JB will work only on AOSP based ROM's like Cyanogenmod, Paranoid, PAC, AOKP and so on, version 4.2 and up!
-The JB build already have this kernel included as it's the only one right now to support JB for our device, but here you can get the latest changelogs and eventually updates for the kernel if not available otherwise.
-[highlight]ION[/highlight] versions of kernel are for ION versions of ROM's, don't use it if you don't know what that means!
-[highlight]DO NOT USE JB KERNELS ON SENSE/ICS ROMS![/highlight]
-Use SetCPU or CPU Master Free(<<my personal choice) in order to activate OC or other Governors and Schedulers, can be found on market
What i say here is just my opinion for the best freq usage possible:
-Stock: Conservative 245 - 1500 Mhz
-Battery friendly: Conservative 149 - 1200 Mhz
-Balanced: SmartassV2 149 - 1497 Mhz
-Kickass: Ondemand 245 - 1800 Mhz
--Best Graphics score: 1497 Mhz
--Best CPU score: 1800 Mhz (you don't say?)
(1497 Mhz was introduced in LTX since 0.7.6)

As the source-code may help others, or if you simply want to see what the code looks like, here it is the gihub link of my kernel, it will be updated as soon as changes are made on it, enjoy the open-source creations!
FAQ:Q: How can i use SWAP?
You need to find a script or to activate it manually, check the xda forum for a init.d script for that.
Q: Will battery last more with this kernel?
On stock values yes, it can be improved by changing VDD voltages and Underclocking.
Q: Will performance be better with this kernel?
It also depends on the ROM you are using, but YES, performance will be better.
Q: What are all the terms around here about?
Check this beautiful and plentiful GUIDE!
Q: Why should i use this kernel?
Because it's better than stock, don't believe me? Try it!
Q: Will you port this or that kernel for our device?
No, but i can include features, just ask for them
Q: With what Toolchain is this kernel compiled?
This kernel is compiled with official Google toolchain version 4.6.3
Q: Why don't you use this or that toolchain to compile your kernel?
Because there is no difference, check this thread for details.
Fanbar:As now the kernel has a little personality, i decided to make a fanbar

Works great with Sense 4.0, thanks mate! Just wondering, after installing setCPU is it only necessary to set mhz to 1804 and nothing else such as governors etc? Anyway, works very fast, good start!
Yes, a so fast battery drain is the only little problem with the kernel...
thanks for this kernal, now my battery consumption in sleep mode is Awesome,,, the day before when i was not using ur kernal it took 30% of battery for one night,,now after flashing this Awesome kernal it consume 3% for whole night... Loved it . Keep going .

WARNING :
This kernel is only for Galaxy S3 International (GT-I9300) version,
and running Android 4.3 (Samsung ROM's) !
Click below to read the full story..
Many of you knows already knows me from my older LiteGX kernel series (for Android 4.1.2 & 4.3).
This time for SimpleGX, I would like to be closer of stock than LiteGX by removing a lot of unneeded things which finally were not gaining any battery stat at all. I had to review everything from zero (once again !).
SimpleGX is only looking for simplicity and stability, trying to aim for best battery life, smoothness and performance experience, than a pure stock kernel.
SimpleGX will now abandon all scripts that I created for LiteGX (even if some of them are still compatible but not recommended).
I really would like to create back a kernel which was my main idea, a kernel “flash-and-play”, nothing to configure, no need to be a nerd, every newbies can have directly best battery life and smoothness once flashed. Of course that’s every kernel cookers wants, but I would not qualify mine as a real “custom kernel”, since it’s not offering any app to configure it and having much more opportunities, at the cost of many random instabilities (freezes, lags, reboots, etc).
There is many differences between LiteGX and SimpleGX, you will have to compare threads if you want to know them.
I really would like once again to give a huge thanks to my friendly devs (post #3) who helped me a lot during all kernel building phase, learning me, and making adventure possible. I can tell also that Google is really a good friend, I confirm that ^^
I still don’t qualify myself as of a real developer, but just a basic person with some android/linux knowledge already.
As always, I’am enjoying sharing my contribution here on XDA for free, which taking me a lot of time to release, so if you can offer me a little beer (as I’am still jobless yet), I will really appreciate that and you will be added into post #4 ! LiteGX had more than 10000 total downloads, I let you imagine if everybody gave me at least a single dollar ! ^_^
This kernel must be only flashed over an official Samsung ROM and not AOSP/AOKP !
Feel free to include my kernel to your ROMs / Threads but please don't forget to inform/ask first via PM and credit me in your original thread.

29.11.2014 : v3.5.1 released.
Updated ZZMoove governor to 1.0 beta4.
Upgrade full ramdisk from XXUGNJ2.
23.11.2014 : v3.5.0 released.
Stock ZRAM activated back with stock values (excepted 80% swappiness, instead of 60 by default), (no more launcher force close within my whole day experience).
I decided to bring back some interesting performance tweaks from my old LiteGX kernel (which are safe, absolutely close to stock and finally sufficient proved):
- writeback: fix occasional slow sync.
- slub.c: little tweak for performance improvements.
- random: increase entropy levels (both read and write).
Overall kernel experience is now more smooth and reactive.
I also changed all download links from the thread to point to my new personnal ftp (so you will now have to click "download link" from post #1). Downloads will now be faster than ever (no more need of dropbox, etc).

Change default governor from pegasusqplus to ZZMoove.
17.03.2014 : v1.1.0 released.
New more "stylish" UI when flashing the kernel.
Revert: "unstable power charging ignored" (charging was really faster but battery was draining much faster also, so back to stock).
Add native xbox controller support.
09.03.2014 : v1.0.0-noIUPC released.
Same version as initial, but with ignore unstable power charging removed, so USB tethering should work again (at the cost of a slow battery charging back).
FYI : the "no_IUPC" version means : no Ignore Unstable Power Charging.
08.03.2014 : v1.0.0 released.
Initial release (check actual features on post #1).

by the way, is there any app by which i can configure the settings? like Stweaks or Boeffla Config?

It's a plug and play, but if you want, you can try trickster for setting stuff like zram on or off, but nothing much to do though.
Your Kernel really rocks. I have been always using your Kernel for close to stock. I am still using LiteGX.
I have tried several one but was looking for one which is hassle free. Your is the one.
This one I will not use now due to USB tethering broken, will wait for next version with that fix.

As long as you flash it on android 4.3 and that the automatical script during procedure won't stop you before checking, then you are good to go
When samsung release his (for example 4.3) source, you can be sure that it will be compatible with every 4.3 future coming firmwares :good:
Sometimes a ramdisk upgrade can also help in some case, so if needed I will do it, no worries

As stated in the story part of post #1, and as Mosh Edd said, this is a flash and play kernel :good: but you can still configure governor settings or some options directly via TricksterMod/SetCPU, etc (don't forget to keep settings after rebooting).

I intentionally disabled stock ZRAM which was on by default via defconfig so no way to activate it manually :angel:
I decided to always disabled it now on SImpleGX, since zram is eating battery a bit and after some ours of use you will face some random lags.

I informed Lord Boeffla about this bug which affects every kernels, he will take a look as soon as he can :good:
By waiting, I will maybe release a "no_IUPC" (no Ignore Unstable Power Charging) version in parallel for each releases, so each one will choose directly if they prefer fast charging or slow charging but with USB tethering working. I intentionally used IUPC as default because wifi it still working to share (for the few I'am using it..) and that I prefer to not wait hours to charge only 10% of my device

Thanks for the reply mate. I just installed and all seem to be fine so far. will test couple of more days and update here.
BTW do we need to clean init.d folder ? i know boeffla andi frequently recommends cleaning up init.d folder. is this necessary with your kernel. Note, i dont have any issues so far (only used few mins though).
Thanks for the advise.

He is right because some init.d scripts can affects stock settings from governors for example or try to enable/disable things that is not from my kernel, etc :good:
For exemple, I'am using NeatROM 6.5 and I can see that there is a lot of scripts in init.d already by default bur they don't affect any of kernel part so it's ok
There's no other solution that checking manually each of them, sadly.
Hi,
Thanks for the new kernel!
I come from the latest LiteGX kernel, so I run the cleaner script before flashing this one. My phone hangs when I reboot. I restarted my phone to get it to boot, but then I now have SwiftKey not loading. What could be the problem?
I reverted back you LiteGX for now.

I flashed kernel last night and waited until phone settled. Checked if all works fine, and it does, and then put the phone in flight mode.
This morning I checked battery stats and it looks like battery was charging a bit while in flight mode (phone was not connected to any power source).
Funny
All is super smooth. Thank you :thumbup:

Strange, as I'am using SwiftKey also and no problem here. If phone hangs at boot this it not normal, did you tried to re-download the kernel from first post ? (maybe a bad download).
If problem still here, maybe try to Try to wipe cache + dalvik from your recovery :good:

I confirm this is funny :laugh:
By waiting, I advice you also to try a wipe cache and dalvik before reaching another 100% and disconnect again to verify :good:
I will try this night aswell to confirm or not if I have the same bug
3.0.31? Why no update to 3.0.101?

Welcome to the official thread for Primal Kernel project for the Exynos Galaxy S7 edge (SM-G935F/FD/W8/S/L/K) running TouchWiz based ROMs (Nougat only currently).
The aim of this project is to provide a rock solid, ready to use tweaked kernel, without useless features.
Introduction:
Primal Kernel, formerly known as The Outsider Kernel, is the first S7 edge kernel for TouchWiz based ROMs sporting the AnyKernel2 installation approach.
The most widespread method consists of flashing a complete prebuilt boot image (this means that it will be flashed straight away without any modification).
This is the most practical method for providing a working kernel, but it has disadvantages too:
1) the installation package will be bigger.
2) the developer must keep the ramdisk updated with the newest from stock kernels. This requires rebasing the patches and keeping up with the newest firmwares sometimes with frequent releases.
3) it makes the compatibility with older ROMs a little more complicated as a newer ramdisk could add modifications not supported by the older ROM.
4) for the ported ROMs the developer has to manually patch the ramdisk with the required changes from the ported device's one. So you have to create a different boot.img for every ported device for every S7 edge variant.
But we have an alternative...
AnyKernel2 is a different approach to the installation of the kernel: the package only contains the prebuilt zImage (the actual kernel), the dtb (basic hardware instructions like reserved memory and so on) and the patches for the stock ramdisk. AnyKernel while installing unpacks the previous kernel and replaces zImage, dtb and, after patching it, the new ramdisk.
This implies various benefits:
1) smaller installation package.
2) you can always have the most updated ramdisk without the need of waiting an update from the developer.
3) better compatibility as you can flash it on top of any stock (or close to) boot image.
4) it makes life a lot easier for the developer with many ready to use patching functions.
5) with some efforts from me, the package can adapt the stock S7 edge ramdisk to work on any S8 or Note FE ported ROM, making it even more adaptable.
All this sounds great (and it is great) but introduces a problem: you can't flash it on top of another custom kernel. This because custom kernels almost always have scripts and other modifications to the ramdisk, which might not be compatible with my kernel.
Installation instructions:
If you correctly follow these instructions you'll be able to run Primal on any ROM (as above).
If it doesn't work, read twice and try installing again before asking for help.
● Instructions for BatMan ROM (S8 port) users:
1) install the ROM (you can dirty flash if you already have it installed) make sure to choose stock kernel (so it doesn't install the new GPU libs, which aren't supported by Primal).
3) after the ROM flashing process has been completed flash the Primal kernel zip for your device.
4) flash your preferred root method.
5) reboot and be patient as first boot might take a little more time.
● Instructions for any other ROM (any other S8 and Note FE ported ROM and, obviously, any S7 edge ROM) running a custom kernel:
1) make sure you have the stock S7 edge kernel zip (or any stock boot.img from any S7 edge Odin package or ROM zip containing the stock kernel) and Primal Kernel zip.
2) if you have a boot.img flash it to the boot partition using Flashify or TWRP itself.
3) if you have the flashable stock kernel zip and Primal Kernel zip reboot to recovery and flash in this order: stock kernel zip, Primal Kernel zip and then your preferred root method.
● Instructions for any S7 edge ROM running stock kernel:
1) reboot to recovery and flash in this order Primal Kernel and your root method of choice.
If you get into a bootloop...
● if you're running a port make sure it says dream2lte (if an S8 port) or gracerlte (if a Note FE port) in the build.prop; if there isn't any add a line at the bottom, "primal=dream2lte" for S8 or "primal=gracerlte" for Note FE.
● make sure your ROM doesn't come with the new GPU libs installed, if it does restore the old libs somehow (flashable zip coming soon!).
Thanks and Credits:
● Samsung OSRC for the kernel source code
● @Tkkg1994 and @jesec for their clear and vast source code and scripts
● @flar2, @UpInTheAir, @franciscofranco, @eng.stk, @osm0sis, @andip71 and others for their great contributions to the community and Android
Features:
● based on the latest Samsung kernel source code G935FXXU1DQH8 merged with G935SKSU1DQG1
● always have the latest ramdisk for your specific model and variant, thanks to AnyKernel2
● ported ROMs are supported (like S8 and Note FE based ROMs)
● compiled with custom built Uber Toolchain 6.4.1 (20170826) and optimization flags
● custom scripts with tweaks applied at boot, optimizations and wakelock fixes
● init.d support
● added a few tested and updated CPU governors (blu_active, conservative, ondemand, powersave, interactive, performance).
default: interactive
● added a few tested and updated I/O schedulers (noop, deadline, row, cfq, bfq, zen)
default: cfq with custom parameters
● added a few TCP congestion algorithms (westwood, reno, bic, cubic, htcp, lia, olia, wvegas)
default: westwood
● full f2fs support from jaegeuk's f2fs-stable plus OnePlus improvements
● fstab mount tweaks for both ext4 and f2fs
● fixed various bugs in the Linux code like improved cyptography algorithms, filesystems, network...
● architecture specific fixes
● cpuidle improvements
● random (entropy) generation improvements
● power managemnet, schedulers, governor and memory management improvements
● unlocked lower CPU frequencies with correct voltages and set recommended defaults (312MHz big - 338MHz LITTLE)
● schedule workqueues on awake CPUs enabled
● improved hotplug and idle with interactive governor
● added 112MHz minimum GPU frequency and clock control
● voltage control for GPU
● LED control with fading option
● voltage control for big and LITTLE clusters
● preset I/O scheduler tunables
● disabled SWAP and ZSWAP for best performance
● preset VM tunables
● SELinux permissive
● Knox 0x0, Samsung security checks and SafetyNet spoofed to pass
● Fsync switch added
● Software CRC control switch added
● and many other changes (too many to be listed here)...
Notes:
● If you want root, you need to flash the root zip after flashing this kernel (Magisk is recommended to pass SafetyNet).
● If you want to access the advanced kernel controls MTweaks by @morogoku is the only app which supports all the features (download it here).
Everything has always been stable, and almost bug free, so no notes on that side at the moment :laugh:
Latest stable version is 2.3.4.

How to set up your phone with f2fs:
1) First you have to install a compatible recovery. Recent TWRP releases can format and mount f2fs, but they don't handle a few installation scripts correcty. I recommend TWRP 3.1.1.0 by @lyapota which has the correct patches. You can find it here.
2) Then you have to backup all your data (internal storage will be wiped too, so make sure to copy ALL your files in the INTERNAL storage). So, any TWRP backup should be taken on external SD card.
3) After this, reboot into TWRP. From Wipe / Advanced Wipe check only /data, then select Change Filesystem and check f2fs. Do the same for /cache. At the moment I don't think there are ROMs that support f2fs on /system too (All the TouchWiz based ROMs force ext4 and format despite settings).
4) Reboot into recovery once again, so we're sure that it can mount everything.
5) At this point you're done. Flash your ROM of choice, this kernel and whatever you want.
Reboot and profit!
ROMs supporting f2fs formatted /system will be listed here when available.
Great to see outsider kernel here ?
Awesome kernel dude!! Thanks for your work
Good work, mate !
nice kernel... quite stable n good performance ...

Thanks for the explanation. But I am confused at the point 3 and 5
In point 3, It is explained that we changed the filesystem to f2fs. But in point 5 explained we are free to flash any rom/kernel. Which I am not clear, with flash rom in f2fs system, will it (force) change to ext4 again? Or even flash fail? Thank you very much

No, it's written that you're free to flash any ROM of your choice and this kernel. As I wrote every TouchWiz ROM forces /system to ext4 so you can only format /data and /cache to f2fs.
Plus, obviously, you're not forces to change filesystem if you don't want to.

I have successfully downloaded 10 hours ago. Just wait for execution only
Download worked finally. Will give it a try soon
like the kernel. Keep up the good work. Can't wait to see how this one develops
how's battery with this kernel?
