leanKernel is not for everyone. My philosophy is to keep the kernel footprint as small as possible by trimming as much fat as possible, and at the same time keeping it stable, power efficient, and fast. You will find that it's lacking some of the bells and whistles of other custom kernels, so if you like features you came to the wrong thread.
The "warranty bit" message at boot is normal.

FAQ
What are ondemandX and interactiveX?
ondemandX and interactiveX are very very close to "stock" ondemand and interactive governors, respectively. The only difference is screen_off_maxfreq sysfs support. This means that it gives you the ability to limit phone's max frequency when screen is off. This feature could be effective in reducing battery usage, especially if you have a misbehaving app (or two) that consume cpu cycles while screen is off. The default value is 1267200 - if you change the value to your top speed you're effectively disabling the feature and restoring stock behavior completely. You can use an app like Trickster to modify screen_off_maxfreq.
Code:
cat /sys/devices/system/cpu/cpufreq/interactive/screen_off_maxfreq
1267200
What is this purple hue/push issue, and do I care?
First if you don't already know about it then you're better off not discovering this. So ignore and move on.
Otherwise, read this thread: http://forum.xda-developers.com/showthread.php?t=2462078
On leanKernel, you can set panel temp to -25 or lower, or panel color to 3 or higher to fix/circumvent this issue.
mpdecision on or off?
leanKernel (for all phones) is a drop in replacement for stock kernel. It is designed to work with mpdecision - I would not turn it off. But then again if you like how the phone is running with it off, go ahead.
my cores are stuck!

Love all these kernel options! Nice work!
THIs is great - thank you. I have tried to flash other kernels that offered OC - but I couldn't get my phone to boot -kept rebooting - not with your kernel - flashed nicely - working very well so far - of course I just flashed it so I need to "play" for a bit but so far so good.
Thanks for your work!

Yup I've been developing custom kernels for a long time. Currently still maintaining gnex (tuna), s3 (d2*), and nexus7 (grouper) leankernels. Been almost exclusively on Verizon until about 2 days ago. Mostly known for my "X" governors - speaking of, I will start working on ondemandX and interactiveX soon.
Glad to see you on this side. Looking forward to seeing more of your work. Hope your enjoying your N3.

I bet you will be able to - I flashed and was able to OC - first time from any of the kernels that are available right now - working really well too - looking forward to running for a while....am on Wicked ROM and all is good!
I only tried Saber, couldn't over clock, but the green kernel was fine. I just changed my max freq with setcpu to max, fine so far. I'm not one to OC, don't see the need, but was more curious to see if it worked.
Sent from my SM-N900T using Xparent Skyblue Tapatalk 2
Which APP for OC Undervolt?
I tried to use Trickster to Undervolt a little and to OC _ but I could not see the frequencies or even change them - SO I used ROM Tool Box and was able to do everything I needed to - do you have a preferred App you suggest or is ROM Tool box as good as anything for this?
Setcpu seems to be the most common. I don't see what would be wrong with rom toolbox, I like their apps.

Imoseyon, I remember your work for the s3 I believe. You make some outstanding kernels! Can't wait for this to hit stable status.

Does the phrase custom undervolting in op mean that this kernal is already undervolted by default?
Not quite sure why Trickstermod does not work right. I think it's a permission/selinux issue. I sent a note to Team Trickster. I think any of the other tools mentioned will work fine.

No the default voltages are stock (for now) - you can use one of the cpu apps to undervolt and go crazy.

Ok thank you sir for your work
Here's another beta update (0.4b): http://androtransfer.com/?developer=imoseyon&folder=hlte
Samsung code is a bit behind CodeAurora, especially the GPU code so I started updating them: gpu, row scheduler, msm cpufreq, etc. Will take a while to completely modernize everything I think. If you run into issues with 0.4b report it here and go back to 0.3b.
Edit: 0.4.2b is the latest - had to revert cpufreq updates due to some bootloops.
Bootloop for me. Anything you want me to try?

Nyan Colonel was originally created for the Epic 4G as an effort to bring all of the features from other Hummingbird devices to the Epic. Now I have used my upgrade on a Galaxy Nexus and have been trying many different kernels and every one seems to have some features and be missing others. I have attempted to add as much features I can while still keeping the kernel lean and fast with great battery life. This does not require you to be some crazy linux enthusiast in order to modify, or charge you for an app capable of tuning it. It comes with the trickstermod app in order to tweak the kernel to your needs in case the preset settings don't fit your user type.

I will attempt to support this as much as I can on xda, but for several reasons (not that xda sucks... it is a great site, but there were some issues with OP length, etc. and it is hard to update on multiple sites), I have my main thread over at rootzwiki...
Anyways, get the full feature list at rootzwiki and I'll just post a basic overview here on this thread.
Source: http://github.com/marcusant/Nyan-Tuna-JB
Description:
Nyan was originally created to port GSM Galaxy S 1 mods over to the Sprint variant. I have since moved to the Galaxy Nexus and have noticed that whenever I would get a new kernel, I would really miss features from the kernel that I was using prior, so that inspired me to make my own kernel for the Tuna.

This is a minimalistic Galaxy Nexus kernel. Imoseyon philosophy is to keep the kernel as lean and stable as possible, at the same time to keep the kernel as modern and close to latest mainstream linux as possible. You will see that my kernels will lack some of the bells and whistles from other kernels.
DOWNLOAD
JB 4.3: [ stable builds | exp builds ] [ change log | exp changes ]
JB 4.2.x: [ stable builds | exp builds ] [ change log ]
Terminal Emulator not finding my scripts? Read this post.
FEATURES
Patched to latest in Linux 3.0.x branch.
All unnecessary kernel components removed to make kernel lean and fast!
OC to 1.65ghz. Boot speed is maxed at 1.2ghz within kernel (in addition to ramdisk) for stability.
User voltage control
InteractiveX V2 (screen-off hotplug of cpu1) added. Select it using setcpu if you want to use it.
Ramdisk tweaks (sysctl, vm, filesystem speed, etc.)
SWAP & zram (next generation compcache) support. Run "zram enable" in terminal.
init.d support in ramdisk.
lk.conf for basic kernel configuration.
HotplugX governor (Hotplug optimized and modified for screen-off suspend).
wakelock tweaks for wlan and lte modem
lkflash - script to flash latest versions of leanKernel from Terminal (type "su" without quotes, hit enter, then type "lkflash" without quotes and then hit enter)
checkv - voltage checking script (for custom undervolting) - detailed at bottom of this post.
checkt - script that displays 1) your current temp, 2) # of times you were throttled due to temp "recently", 3) CPU trim type, and 4) CPU silicon type, etc. (sample output)
Fast USB charge (by chad0982) and "ffc" toggle script by me. (Open terminal, and type "ffc" without quotes then enter)
ColorControl from both CM9 and Ezekeel (compatible with all ROMs). Helpful posts: 1and 2.
TempControl - sysfs interface to control the CPU temp threshold. Read these two posts: 1 and 2.
Variable GPU OC - sysfs interface to select GPU max speed between 307MHz (stock), 384MHz and 512Mhz. The changes take effect immediately. Check FAQ for more info and how to use it.
Custom SR Tuning - override kernel default minimum voltage for SR calibration. More info here and here. V2
SoundControl
Gamma Control
ROW scheduler v4

Yeah. The main thread is on RootzWiki. It is a very popular kernel there. I have had people tell me to try all the other kernels because they're better. I've tried them all and I keep using this one. Its light,runs smooth,and helps battery life. What more could you want .

LeanKernel is my every day kernel i used and use now with every ROM i tried on GNex.
My last two days of using the kernel and its great... I never gave any comments for any thread in favor of it but this is first one ) even franco or other kernels.. They have some hot stuff to offer but at the cost many things, specially battery..this one is optimized for battery specifically...

For those who have stuck with the Incredible 2 through thick and thin, we finally have an ICS kernel for Sense. Here is my personal build for everyone to use as they so desire. This is built from the Chinese source.
This kernel includes: Overclocking, Governers, IO Schedulers, Forced Fast Charge, Dynamic Fsync, BFS & CFS versions, tiny RCU, and more to come...
Difference between this kernel and bsmitty83's:
BrYCS - built with arm-eabi 4.4.3 toolchain
KaPoW - built with gcc linaro toolchain, and patched up to 3.0.xx (and more frequent updates - the guy is a machine)
RIOT ACT: ...blah blah blah...flash at your own risk...if you brick your phone...you're a dumba$$...I am not responsible.

Yeeeeeeeesssss
i'd like to thank our good friends over in china for releasing the kernel source for the s710d
I can confirm that the kernel works on the ICtazz rom
Tried this kernel on the 7.01.605.01 Verizon Sense Vivow Ics rom...
Everything works! Quickly ...
brymaster5000 - you're super!
Nice Job! This should improve the viper rom's stability no? I'm also assuming you will be adding OC's and governors?

You got it. I wanted the kernel to be out first before I started messing with it. But yes, my next step (hopefully later today) is to add oc and governers.

I'm a bit confused, I thought this was for ICS sense roms. Exactly what will this kernel work with? Sense only? ICS only? AOSP only?
So this is to be only flashed on sense based roms?

Awesome, let us know how viper works. Viper is one of my favorite roms but I quit using it because of lag, im hoping this kernel takes care of that. I would test if I could right now but need my phone for work right now.

I used Viper for the configuration file - and am running it now. Works great. Not sure about the Psycho 9.1 ROM...can't say I even knew about it until now.
On your custom kernel bry you should enable fastcharge
and maybe UV :beer:

Added some governers...and getting some build errors. Will try again later.
I will look into fast charge.
Can one possibly love the devs of this phone too much?
im trying to port MIUIv5 using ROM Porter with chilli's cm10 as base and the IncS miuiv5 as port
apparently my phone does not like to go past the loadscreen when the rom is signed, but when unsigned it boots just fine after one forced reboot (does it by itself first boot)
at first it was giving me endless com.process.phone and com.process.acore errors
now its just sitting there in the boot screen again.
Any advice guys?
Screenlock won't let me enter a numeric pin, the keyboard is absent.
Password works though.

Wait 10 minutes
Enjoy the Lightning Zap!
See 3rd post for further instructions on improving and customizing your Lighting Zap! experience.
**The first boots always takes the longest especially after a fresh install. If you pull a logcat during the first boot, you may see a few errors with the vacuum script. This is normal, and will be "fixed" after the phone has built the databases for the apps.
Please allow 24 hours after install and 1 full charge cycle before reporting results. Always provide me with a logcat with any issues you may experience.
Phase 1: Introduction of LZ kernel to device

elport for testing
and the rest of the testers (pm me and I'll add your names guys)
Download links and changelog
If you have rotation problems try this (thanks to bilgerryan): http://db.tt/b6GG7eU1
If you use TWRP, you may have to fix root perms before you reboot...
ATTENTION: I am only updating the smdk4412 (new kernel) at this time. I believe most ROM devs have updated thier sources to use the smdk4412
If your ROM isn't yet compatibile with the new kernel, first talk to your ROM dev. If you ROM dev is not willing or unable to update
then let me know, and I will try to make the time to configure my sources for compiling the smdk4210 and update it. Otherwise, you
will have to wait till I can get to it.
smdk4412_p4.zip New kernel (link coming soon)
p_4
Added phase 1 thru 3.1 from old kernel
Bumped to 4.
cherry-picked from AGAT_GB27_kernel. Thanks agat63!
Added OC to 1.6
Added UV
Edited bus frequencies and a whole bunch more
Voltage Control app still not working properly, but well enough...lol (I'm still working on it)
smdk4210 Old kernel
p_3.1
Bumped to 3.1.
Added lionheart governor.
Fixed smartass2 governor.
Added vr-ioscheduler.
p_3
Bumped to phase 3.
Added hypervTNT (with phase 2 and 3 stepping) and smartass2 governors.
Working on voltage control app compatibility
E4GT_p2.zip
Bump to phase 2
Minor adjustments on system control values
Added Xan's Voltage Control App (This will come in to play very soon)
E4GT_p1.1.zip
Introduction of Lightning Zap!
Known bug. This might goober up gapps. So, be aware you might have to reinstall gapps. I'm working on it now...
More tips and tricks
The governor tweak is set for a fairly balance of performance and battery life. If you find yourself needing battery life over performance, you can make some minor changes. Here's how:
1 Download Script Manager from the market (it's free)
2 Open Script Manager and navigate to /system/etc/init.d
3 Press menu/more/advanced options and select mount as RW
4 Select 01governor and select "edit" at the top (this will open the file in a text editor)
5 Uncomment (remove # in the particular line) and change:
Code:
echo "45" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold;
To:
Code:
echo "[COLOR=red]70[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold;
Only change values in increments of 5 for the up_threshold.
6 Select menu/save
7 Press the skull and cross bones icon at the top (this will allow Super User)
8 Press run, close app and enjoy
This will result is slightly slower performance but higher battery life.
When running in a higher performance mode (especially for gaming) you can disable powersave_bias by changing the 1 to a 0 like this:
Code:
echo "1" > /sys/devices/system/cpu/cpufreq/ondemand/powersave_bias;
echo "[COLOR=red]0[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/powersave_bias;
Powersave_bias only allows the CPU to peak for small increments at a time, and not allow the CPU to remain peaked even when the system calls for it. In gaming, that could result in choppy, laggy perofrmance and slow FPS..
This is now controlled by the kernel. You can still change the values, but be careful as too low can result in camera and graphics issue and too high can seriously drain your battery
Changing the sampling rate controls smoothness and responsiveness. I set 150000 as default
Code:
echo "[COLOR=Red]150000[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate;
I am not responsible if you do something wrong. Make a back up just in case.
How to incorporate LZ kernel into your ROM.
First you would add the kernel and vendor files to your manifest, then repo sync. I'm not going to tell you how to do this because I think if you are compiling a ROM you probably already know how. If not, let me know, and I'll post that up to.
Then, in device/samsung/d710/d710.mk add:
Code:
# Adding Lightning Zap! vendor files
$(call inherit-product-if-exists, vendor/lz-kernel/E4GT/lightningzap.mk)
Then compile as normal, and you will have the complete Lightning Zap! kernel package.
You are the man thanks again for taking this on can't wait

its a pretty bad ass kernel man im loving it
To start the on demand gov is set as the default gov and is the one that is optimized for the kernel...
You can play around with the govs but keep that in mind
Also as far as tweaks go you shouldn't use any because they could mess things up.. If you do use them and have problems please don't waste my nor Thomas time until you reflash the kernel to remove the scripts and verify that the problem is the kernel thanks

Ask AGAT about making sure the kernel is Extweak compatible once you get to that phase. It allows CPU/GPU Overclocking, OV/UV, etc ,etc. You can sample it using GB27+AGAT's Custom Kernel, but it isn't saving the settings right now on GB27.
Awesome work. Possible bug when screen rotates to landscape it won't go back to portrait workout turning phone upside down then as fast as I can flip the phone otherwise it goes back to landscape, locking and unlocking screen also fixes, more of a work around. Running pac.
