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 release​If 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:

all other editions are the same as before, only GuesteOC has been updated and they have been recompiled (couldn't avoid)!
AROMA installer package has been built automatically by my new enhanced kernel building script
AROMA installer package allows you to choose between 6 different kernel editions, and allows you to set max. CPU frequency, RamHack size, desired IO Scheduler and ZRam enabled/disabled right during the installation of the guestekrnL kernel
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?
Click to expand...

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

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

In any case I think this should stay and finished, sure everything is clarified and two, two developers, along with others are keeping alive our mobile and certainly is welcome. Greetings to all

hi, wow, good luck with the kernel i made my non overclock kernel in our local forum based on v20q for stock based rom like gr6...
make sure you got a lot of free time, doing kernel and rom at the same time takes time a looooot.....

y r u so hooked up on proving stefan innocent, how do u know he didnt mean to critize spica, and y dosent stefan clear the foul air himself on this thread.
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)​

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 ANDROID 4.1.2 (SAMSUNG) !
This is a pure LITE, STOCK WAY & STABLE kernel with MINIMAL features.
If you are looking to a kernel with less features and more close to stock, check out my StockGX kernel.
My goal is to offer a slight modification of our Samsung stock kernel's, with few features, aiming a better battery life than stock without affecting any drain.
This is a kernel "plug-and-play" or I would say more "flash-and-play". No need for tools or apps to configure the kernel. This is the way I wanted it. A bit like speedmod kernel did.
Unfortunately, I'am not a developer but just a basic person with some android/linux knowledge already.
My dream was one day to create my own kernel, and thanks to great developers that answered my many questions, this dream has been possible. I'am very happy and proud to share my first ever kernel to everybody here.
It 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.​​

★ PREREQUISITE ★ :​
Any odexed or deodexed international I9300 Samsung 4.1.2 Jelly Bean ROM.
A custom recovery (CWM recommanded) to flash the kernel.
★ FREQUENTLY ASKED QUESTIONS ★ :​
How can I customize this kernel ? :
> Mainly with ZZMoove/zRam profiles (grab them below) and with TricksterMOD / SetCPU apps.
What does the LiteGX cleaner script ? :
> It deletes all ZZMoove/zRam profiles that you flashed after this kernel. So you can go in another kernel safely. It don't removes anything else since this kernel is pure stock based and don't add any files/folders that need to be deleted after. This cleaner script will be only efficient in this situation only, it does not clean anything before coming from another kernel to mine.
Do I need to wipe cache + dalvik each time I flash a new kernel version ? :
> Nope. Moreover dalvik cache is already wiped automatically during flashing procedure.
Do I really need to flash any profiles/scripts ? :
> Definitely not. It's user choice to do it but zRam profiles for example are highly recommanded to be flashed since it adds a lot of smoothness and performance to the kernel (and on which is disabled by default).
Do I need to re-flash ZZMoove ZIP profiles each time I flash a new kernel version ? :
> Nope. It just install an init.d script, so it will be permanent until you delete files from your init.d folder or flash "Cleaner" version which will do this for you.
Do I need to remove old ZZMoove profiles manually before flashing a new profile ZIP ? :
> Nope. Each ZIP's include an automatic removal of previously used profile.
Android OS usage is very often at top of my battery stats ! :
> Try wiping cache and dalvik cache manually in your favorite CWM, then make a full charging until green led appears.

- Touch-to-Wake_disabled(stock).zip
- Touch-to-Wake_enabled_3s.zip
- Touch-to-Wake_enabled_5s.zip
- Touch-to-Wake_enabled_8s.zip
- Touch-to-Wake_enabled_10s.zip
- Touch-to-Wake_enabled_15s.zip
Updated "LiteGX-KERNEL_full_cleaner.zip" to match new Touch-to-Wake flashable ZIP's (please remove old one).
15.12.2013 : v5.5.0 released.
ramdisk : re-enabled lowmemory killer in 'init.rc'.
SCHED_MC disabled back by default (0) to avoid some people facing some lags due to agressive value (moreover, I prefer to trust ZZMoove stock behaviour).
Added some "SCHED_MC profiles" into scripts folder :
- "SCHED_MC_power_savings_0(stock).zip"
- "SCHED_MC_power_savings_1.zip"
- "SCHED_MC_power_savings_2.zip"
It will be useful for those who wants to change it without the need to use TricksterMOD (etc) anymore.
Updated "LiteGX-KERNEL_full_cleaner.zip" to match new SCHED_MC flashable ZIP's (please remove old one).
05.12.2013 : Flashable ZIP's adding.
Added some "TCP congestion profiles" into scripts folder :
- "TCP-congestion_bic.zip"
- "TCP-congestion_westwood.zip"
- "TCP-congestion_htcp.zip"
- "TCP-congestion_reno.zip"
- "TCP-congestion_cubic(stock).zip"
It will be useful for those who wants to change it without the need to use TricksterMOD (etc) anymore.
Updated "LiteGX-KERNEL_full_cleaner.zip" to match new TCP flashable ZIP's (please remove old one).
02.12.2013 : v5.4.0 released.
zRam is disabled as default again (this time for ever), for battery purpose at the cost of a bit less multitasking (if you want it again : just flash any zRam script).
"GENTLE_FAIR_SLEEPERS" disabled (back), should improve UI responsiveness.
Updated "zRam_disabled.zip" to match new zRam disabling as default (please delete old one).
28.11.2013 : v5.3.0 released.
zRam is now initialized by default once flashing the kernel with 600MB disksize and 100% swapiness. If you feel some lags, try different values with scripts (hope it will help people finding this kernel more smooth than default without it).
All zRam scripts has been reworked and updated (please delete olders and download latest ones). If you want to turn off zRam, this time you'll have to flash "zRam_disabled.zip" file.
zRam initialization is now using a custom busybox binary directly integrated in the kernel, it will avoid some people not having their zRam properly working due to some roms busybox which cannot execute 'swapon' shell command and with priorities.
- A little reminder : to check if your zRam is working, no more need to install Turbo zRam app, on a Terminal, write : "free" (if you see swap values, then zRam is working) or "cat /proc/swaps" (which will give you more informations on both 4 swap partitions).
- I would like to thanks personally my friend @Yank555 to help finding some zRam initialization problems.
Clic below to see older changelog ..

17.11.2013 : v4.6.2 released.
ramdisk : Fixed zRam which was enabled at boot by default.
ramdisk : Modified 'root helper tweaks' (again) to remove many useless lines, which finally now finally looks like more as an 'init.d helper'.
ramdisk : Many useless files in 'sbin' folder has been removed to let only needed ones for 'root helper tweaks'.
Overall kernel size is now slightly lighter than before.
14.11.2013 : v4.6.1 released.
ramdisk : included 'root helper tweaks' from adam kernel but modified to fit the needs of LiteGX kernel only (removed build.prop and pegasusq governor tweaks).
10.11.2013 : v4.6.0 released.
Updated compilation toolchain Linaro GCC from 13.09 to 13.10 (20131014).
05.11.2013 : v4.5.6 released.
AIO enabled.
Backport AIO from Linux 3.6.x.
AIO tweak : Don't plug the I/O queue in do_io_submit().
03.11.2013 : v4.5.5 released.
Enabled "ARCH_POWER" to use 'arm_cpu_topology' power management features.
litegx_defconfig : Added "CONFIG_TOUCH_WAKE".
28.10.2013 : v4.5.4 released.
Disabled "GENTLE_FAIR_SLEEPERS" (should improve UI responsiveness).
27.10.2013 : v4.5.3 released.
"sched_mc_power_savings" set to aggressive value (2) by default.
17.10.2013 : v4.5.2 released.
Decreased touch boost frequency from 1000 to 600Mhz (should slightly decrease smoothness, but be a bit more battery friendly).
15.10.2013 : v4.5.1 released.
Increased touch boost frequency from 800 to 1000Mhz (should boost smoothness a bit without affecting much battery).
09.10.2013 : v4.5.0 released.
Kernel logging (linux printk) disabled (credits to @Lord Boeffla).
litegx_defconfig : disabled some more debug.
05.10.2013 : ZZMoove profiles updated.
All ZZMoove profiles updated to latest revision (thanks to @Yank555).
Removed "ZZMoove_LCDFreq_optimizations_removal.zip" and included it directly in "ZZMoove_Profiles_Cleaner.zip" instead.
Changed priorities into scripts for init.d : "S98" for every ZZMoove profiles and "S99" for LCDFreq optimizations, to override ones already included in S98 profiles.
Modified "LiteGX-KERNEL_full_cleaner.zip" to proper remove new "S98" profiles.
01.10.2013 : v4.4.4 released.
zRam is now disabled by default (to stay as stock as possible).
zRam : set default to 4 devices instead of 1 (resulting Turbo zRam app compatibility from @rlorange).
Removed all zRam scripts to create some new with 4x zRam swaps instead of single ones. Should be MUCH smoother than single zRam (not a single lag detected after hard use of few hours). As always, you can flash new zRam scripts without the need to delete anything from init.d, since it will do it automatically.
Please remember that all my provided scripts are NOT necessary. They are just here for confirmed people or those who wants to increase smoothness or battery life a bit. Stock flashing will always provide best balance. Don't worry, this kernel will always stays like I wanted to do it : a "flash-and-play" one firstly.
29.09.2013 : v4.4.3 released.
Changed default zRam swappiness value from 90% to 80%.
Restored Boeffla Sound v1.6.4 original work with saturation prevention, since it was useless to remove it (just select "Over-saturation Supress" in "Graphical Equalizer" in Boeffla Sound app).
29.09.2013 : v4.4.2 released.
Changed default zRam disksize and swappiness values from 200MB / 10% to 600MB / 90% (thanks to @Yank555 for the tips).
Added 3 new zRam scripts with 90% swappiness.
29.09.2013 : v4.4.1 released.
Updated compilation toolchain Linaro GCC from 13.08 to 13.09 (20130903).
27.09.2013 : some changement about scripts.
All "ZZMoove profiles" has been removed from post #1. You can grab now them directly at top of post #2.
Added several zRam profiles (300/600/800 MB disksize, and 80/100% swappiness) scripts.
Added a full cleaner ZIP for those who want to remove cleanly everything from this kernel and want to migrate to another one.
27.09.2013 : v4.4.0 released.
Introducing zRam (with stock values for the moment). Should increase performance. Use zRam & Swap Control (made by @rlorange) to set your values and make init.d scripts like you want; or directly use my scripts HERE.
zRam : added LZ4 compression and using it as default.
Activated native ExFAT support.
Now using "make mrproper" (instead of "make clean") to stay with local number #1 (thanks @googy_anas for the tips).
22.09.2013 : v4.3.5 released.
ipv4: save CPU cycles from "check_leaf()" (backport from linux 3.8) (thx @googy_anas).
22.09.2013 : v4.3.4 released.

Updated "Dynamic FSync control" from v1.1 to v1.2 again.
NTFS support.
NFS support again.
CIFS support again.
sched: LOAD_FREQ tweak (this time definitely) removed.
18.09.2013 : v4.2.0 released.
Fixed "Dynamic FSync control" which was not working ("dyn_sync_cntrl.c" file was missing).
CONFIG_SCHED_AUTOGROUP enabled again (smoothness should be back).
Added again : Intelli memory writeback (0 when screen ON & 500ms when screen off).
Added again : sched: LOAD_FREQ (4*HZ+122) avoids loadavg Moire.
Touch-to-Wake back from v1.1a to v1.1 for the moment.

Litest release ever (5,42 MB), smoothest and best battery friendly release ever too.
Releases will now be "x.x.x" (latest number for minor fixes/tweaks, the middle one for good ones, and the first one for major ones).
Removed a lot of tweaks since v3.6, which was useless or that I don't want to include anymore to stay as close as possible from stock. I prefered to let only important and relevant tweaks for now.

CIFS / NFS support removed.
Intelli memory writeback removed.
AIO tweak: No plug I/O queue in "do_io_submit()" removed.

Yeah, I will compile it using linaro toolchain soon (already tried but had some errors when compiling resulting an abort. Need to learn a bit more flags configuration for compiling, hehe) :good:
Stay tuned!

Androidgx nice work.
For linaro 4.6 and above you will require this patch https://github.com/AndreiLux/Perseus-S3/commit/71f536fb9957c64cc6274221faa056694e010616
After this you're good to go with Linaro toolchain

Thanks mate :good:
You write at the good moment, was currently trying to compile and learning how to compile right without errors using linaro gcc 4.7
I stay you tuned!

Androidgx,
This is the simple fsync which I wrote in 2012 which turns fsync on untill phone is booted and later after ,it"s booted it turns off fsync.
Plus the code has been optimized with branch prediction feature of cortexa-9 cpu by gcc accembly code and it does use cortex-a9 's preload engine (prefetch) to keep fsync state in L2 cache. Plus by branch prediction there is a less cpu overhead checking about whether fsync is on or off. It assumes fsync is off and with probable branch prediction it executes faster.
Below is the fsync as a patch which I wrote in mid 2012 for my older phone. You can use it .The basic fsync functional code is based on alrahi's code.
Simple Fsunc patch is here: http://db.tt/rdikFoKY

Any idea ?
Maybe another flag need to be removed ?

Androidgx,
Seems like this will solve it.
Open file drivers/video/samsung_extdisp/s3cfb_extdsp.h
Now goto line 154 and remove the word "inline" before struct declaration or add "static" before inline. Save file and try to compile back

Thank you mate it worked almost perfectly after. Just faced the same problem as THIS guy before finishing compiling, followed exactly what he said (replacing the Makefile completely, and it worked, finally :laugh. I just hope it was the right way to do.
Currenty testing my fresh new kernel with linaro 4.7.4 gcc toolchain thanks to you.
Btw, about your fsync tips patch you send me, I have very poor knowledge, is this something really noticable in term of difference as stock ? I mean a good improvement over ?
Many thanks for your explanations :good:

does this kernel supports exfat sd cards ???

hello sir, can you please make early suspend values for CRT OFF Effect Configurable via Trickster Mod App, as i want to set it to 0ms.

thanks for your work, I was looking for a kernel like this. I understand the purpose of this kernel, but do you think it would get your kernel too far from stock if you include row and, maybe, optional zram?

I'm a fan of gx kernel. I'm trying this now.
Suggestions:
- please add mdnie for better readability
- if you ever add zram and/or zzmoove, please make them default and with the best profile so that we don't have to flash profiles, that way, we can really say that it's flash-and-play.

Sorry, no plan to add this. Anyway a value of 100 won't affect battery life don't worry, just ignore it

- ROW scheduler : I can. I will maybe add ZZMoove governor aswell. But this time they won't be set as default for both :good:
- Optional zRam : no plan to add this, I let this feature to LiteGX kernel only

- hardcore mDNIe : no plan for this (only for LiteGX) but I included Black Crush fix for original samsung colors instead.
- zRam : same answer as above.
- ZZMoove gov : same answer as above. It will be default only in LiteGX.
Sorry, overall this kernel will stay very very lite and will almost have no more features included to stay absolutely close as stock as possible. Will keep it updated mainly for samsung sources, ramdisk (if better), and toolchains.

Hi, any chance to see TRIM support enabled in this version of Kernel? Thanks!!!!

Since i have updated to the latest 1.2 version, my phone battery charges very very fast, in 45 minutes but also discharges very very fast, in half a day. Is that a bug or should i flash 1.0?

It reminds me that I had same issue into some other kernels many months ago. Stock charging is not so optimized, sometimes it can charge fast and sometimes very slow, I would say it's the normal behaviour, but did you checked your wakelocks with BetterBatteryStats ? we never know..

UPDATE

WARNING :
THIS KERNEL IS ONLY FOR THE GT-I9300 AND ANDROID 4.3 (SAMSUNG) !
This is a pure LITE, STOCK WAY & STABLE kernel with MINIMAL features.
Many of you knows my Android 4.1.2 LiteGX kernel, here is the 4.3 version !
My goal is to offer a slight modification of our Samsung stock kernel's, with few features, aiming a better battery life than stock without affecting any drain.
This is a kernel "plug-and-play" or I would say more "flash-and-play". No need for tools or apps to configure the kernel. This is the way I wanted it. A bit like speedmod kernel did.
Unfortunately, I'am not a developer but just a basic person with some android/linux knowledge already.
My dream was one day to create my own kernel, and thanks to great developers that answered my many questions, this dream has been possible. I'am very happy and proud to share my first ever kernel to everybody here.
It 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.​​

★ PREREQUISITE ★ :​
Any odexed or deodexed international I9300 Samsung 4.3 Jelly Bean ROM.
A custom recovery (CWM recommanded) to flash the kernel.
Be sure to remove any of your init.d scripts which can meet conflicts with ones I provide.
★ FREQUENTLY ASKED QUESTIONS ★ :​
Do I need to flash any cleaner script before flashing this kernel ? :
> If your previous custom kernel dev provided a cleaner script, then you can flash it before flashing mine.
How can I customize this kernel ? :
> Mainly with ZZMoove/zRam profiles (grab them below) and with TricksterMOD / SetCPU apps.
What is zRam and his pros/cons ? :
> Check THIS interesting answer from @Yank555.
Which zRam script should I choose ? :
> Check THIS interesting answer still from @Yank555.
How to check if flashed zRam script is really currently in use ? :
> You can check it directly by using "cat /proc/swaps" or "free" shell commands via a terminal.
What does the LiteGX cleaner script ? :
> It deletes all ZZMoove/zRam profiles that you flashed after this kernel. So you can go in another kernel safely. It don't removes anything else since this kernel is pure stock based and don't add any files/folders that need to be deleted after. This cleaner script will be only efficient in this situation only, it does not clean anything before coming from another kernel to mine.
Do I need to wipe cache + dalvik each time I flash a new kernel version ? :
> Nope. Moreover dalvik cache is already wiped automatically during flashing procedure.
Do I really need to flash any profiles/scripts ? :
> Definitely not. It's user choice to do it.
Do I need to re-flash ZZMoove ZIP profiles each time I flash a new kernel version ? :
> Nope. It just install an init.d script, so it will be permanent until you delete files from your init.d folder or flash "Cleaner" version which will do this for you.
Do I need to remove old ZZMoove profiles manually before flashing a new profile ZIP ? :
> Nope. Each ZIP's include an automatic removal of previously used profile.
My TricksterMOD settings are losed after rebooting ! :
> I won't learn how to use this app but to make short, once you set any value (or modify anything), click the "V" icon at top right to apply new value, then press settings icon of the app (still on top right) and tick kernel parameters option to apply settings at boot.
Android OS usage is very often at top of my battery stats ! :
> Check THIS interesting thread. Moreover it looks android 4.3 source known related problem, hopefully will be solved in another next source.
My device is getting hot at load (games) or high usage ! :
> Check THIS interesting answer from @ZaneZam.
I lost my WiFi connexion ! :
> Be sure to flash an efsV2 modem (XXUGMK6+ minimum).

Added hardcore mDNIe sharpness & colors tweaks. Colors profiles remains intact, so they still can be activated in display section (which was not the case in LiteGX for android 4.1.2).
Clic below to see older changelog ..
01.01.2014 : v4.1.1 released.
Removed (temporarily) Triangle Away support (incompatible with Android 4.3 yet), to avoid force close messages.
30.12.2013 : v4.1.0 released.
ramdisk upgraded to XXUGML2 (Android 4.3).
29.12.2013 : v4.0.0 released.
Now based from official Update13 XXUGMK6 source from Samsung.
Now compiled with stock Android ARM EABI 4.4.3.
Reverted: "Enabled persistent TRIM support for all partitions" tweak (since samsung already included it in Update13 now).
Touch-to-Wake is now disabled by default (for battery purpose).
Added some "Touch-to-Wake profiles" into scripts folder :
- Touch-to-Wake_disabled(stock).zip
- Touch-to-Wake_enabled_3s.zip
- Touch-to-Wake_enabled_5s.zip
- Touch-to-Wake_enabled_8s.zip

15.12.2013 : v3.6.0 released.
Upgraded to XXUGMK6 Android 4.3 ramdisk (from official LEAK this time). In case your old modem is not working anymore, update it to THIS one.
SCHED_MC disabled back by default (0) to avoid some people facing some lags due to agressive value (moreover, I prefer to trust ZZMoove stock behaviour).
Added some "SCHED_MC profiles" into scripts folder :
- "SCHED_MC_power_savings_0(stock).zip"
- "SCHED_MC_power_savings_1.zip"
- "SCHED_MC_power_savings_2.zip"
It will be useful for those who wants to change it without the need to use TricksterMOD (etc) anymore.
Updated "LiteGX-KERNEL_full_cleaner.zip" to match new SCHED_MC flashable ZIP's (please remove old one).
12.12.2013 : v3.5.0 released.
Upgraded to XXUGMK6 Android 4.3 ramdisk.
05.12.2013 : Flashable ZIP's adding.

- "TCP-congestion_westwood.zip"
- "TCP-congestion_htcp.zip"
- "TCP-congestion_reno.zip"
- "TCP-congestion_cubic(stock).zip"
It will be useful for those who wants to change it without the need to use TricksterMOD (etc) anymore.
Updated "LiteGX-KERNEL_full_cleaner.zip" to match new TCP flashable ZIP's (please remove old one).
02.12.2013 : v3.4.0 released.
zRam is disabled as default again (this time for ever), for battery purpose at the cost of a bit less multitasking (if you want it again : just flash any zRam script).
"GENTLE_FAIR_SLEEPERS" disabled (back), should improve UI responsiveness.
Updated "zRam_disabled.zip" to match new zRam disabling as default (please delete old one).
28.11.2013 : v3.3.0 released.
zRam is now initialized by default once flashing the kernel with 600MB disksize and 100% swapiness. If you feel some lags, try different values with scripts (hope it will help people finding this kernel more smooth than default without it).
All zRam scripts has been reworked and updated (please delete olders and download latest ones). If you want to turn off zRam, this time you'll have to flash "zRam_disabled.zip" file.
zRam initialization is now using a custom busybox binary directly integrated in the kernel, it will avoid some people not having their zRam properly working due to some roms busybox which cannot execute 'swapon' shell command and with priorities.
- A little reminder : to check if your zRam is working, no more need to install Turbo zRam app, on a Terminal, write : "free" (if you see swap values, then zRam is working) or "cat /proc/swaps" (which will give you more informations on both 4 swap partitions).
- I would like to thanks personally my friend @Yank555 to help finding some zRam initialization problems.
21.11.2013 : v3.2.0 released.
Add several TCP congestion control modules :
- Westwood
- BIC
- HTCP
'cubic' TCP congestion will stay as default like stock. You can set your favorite congestion module via TricksterMOD app.
20.11.2013 : v3.1.2 released.
ramdisk : add same root helper files + modifications as v2.1.0. Hopefully it will definitely fix root losing (for some people).
20.11.2013 : v3.1.1 released.
ramdisk : add 'root helper' again to avoid losing root after flashing for some people.
19.11.2013 : v3.1.0 released.
Enabled back: Persistent TRIM support for all partitions.
Enabled back: USB charging increased (to 900mA instead of 475 by default).
18.11.2013 : v3.0.0 released.
Total redesign again from Samsung update1 (SEA) chinese source.
Removed a LOT of tweaks (back to 'stock way' for real), battery life should be much better than before.
List of removed tweaks :
- Removed: NTFS support.
- Removed: CIFS support.
- Removed: NFS support.
- Removed: Proportional Rate Reduction for TCP.
- Removed: Network speed tweak.
- Removed: Decreased touch boost frequency (from 800 to 600Mhz).

Overall kernel size is now slightly lighter (again) than previous version.
17.11.2013 : v2.1.1 released.
ramdisk : Modified 'root helper tweaks' (again) to remove many useless lines, which finally now finally looks like more as an 'init.d helper'.
ramdisk : Many useless files in 'sbin' folder has been removed to let only needed ones for 'root helper tweaks'.

ramdisk : modified 'root helper tweaks' from adam kernel to fit the needs of LiteGX kernel only (removed build.prop and pegasusq governor tweaks).
It was already the case before but I prefer to precise it : in case you encounter the message "fix root" after flashing my kernel before rebooting from recovery, you can choose yes or not, it will be the same : you will not loose root.
11.11.2013 : v1.6.1 released.
touch_wake.c : forgot description of bump to 1.1a.

Many thanks to @letmarebrmbarove ! :good:
Many thanks to @batahulu ! :good:
Many thanks to @sqlpro ! :good:
Thank you to support my work guys !

Hi,
Firstly, thank you for your hard work on this kernel.
I flashed the kernel after wiping cache and dalvik. What I noticed is that Trickster mod does not pickup all 4 cores. Only 1 core is shown. Also, frequency lock is set to On, but no frequencies are shown. No scheduler is shown either. Cpu -z shows all cores.
Other than that, everything is running smoothly so far. The wake lock issue doesn't seem to be present. I'll report back with any other issues I find.
Thank you again. I've been using your Kernels since I bought my phone and I find them to be perfect for my needs.
Edit: I'm using Gorgoid 3.2

flashing right now. thanks
EDIT: wake up bug is gone. everything seems ok for a few hours of using. next is battery life. charging right now.

Thanks, you did it faster than i expected, will flash 4.3 this weekend.

Awesome i will try it now and tonight or tomorow i will give feedback .
Hope batterylife is better than stock and the wake up bug is gone .
Thanks for your work
modded by Xposed Framework.

Thanks for your work! :good:
Waiting some feedbak from users, but for sure I will try it :highfive:

Thanks guys, glad you like it, even if it's still far than my 4.1.2 LiteGX version, still a lot of work to do!

I can confirm this bug, looks like TricksterMOD is not well supported by 4.3 detection for the moment I guess. Try to use SetCPU for the moment which works well, and PerfMon to see behaviour of 4 cores in live, looks like all cores are working properly here :good:

Thanks to informing me about this bug, I wasn't aware of it, since I just migrated to 4.3 yesterday.
For the moment I never encountered this bug so far, but I'll let you know as soon as I'll face it.
I just hope official update12 source solved it, of we will have to wait for non-official dev fix, or future update13 source :cyclops:

Thank you. I'll Perfmon. I don't really play around with cpu settings much, although I do use Trickster mod to check that everything is running the way it should.
Another issue just noticed while typing this post is that my phone is heating up. Cpu-z reading is 40° C. Not sure if it's a 4.3/chrome/kernel issue. I never had this problem 4.1.2 using Chrome.

One more kernel for 4.3. This is really good!
Thanks man!

Thank you

Major update !

Btw, I found the buggish patch who caused a freeze into samsung I9300 boot logo, it was caused by linux printk, so no kernel logging disabled for the moment.

Looks Nice
Added as always ( Pardus HD Rom Premier 4.3 ) :good:

Thank! I will try flash right now!! I Love your kernel for 4.1 , hope this version can fix bug lockscreen delay and batterylife!

Testing on Neatrom..
