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.

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

Enjoy!
I've found a bug, what shall I do?
First of all, make sure this bug does not occur on the non-linaro Franco kernel. Second, make sure it's not caused by your rom, if you've flashed this kernel at the same time you flashed a linaro ROM, it's much more likely the issue is caused by a bug in the ROM.
If you're sure that the bug is definitely specific to the linaro franco kernels, post your logcat and kmsg (from /proc/last_kmsg - if you encounter a bug, reboot first in order to generate /proc/last_kmsg, then grab it and upload it), along with the name of the kernel .zip you flashed and ideally instructions on how to reproduce the bug.
Current Known Issues:
None
READ THIS:
What's different about the *.5pcOC.* archives?
This kernel is built with a 5% static board overclock, as of r186 Franco's normal builds no longer use any static board overclock. Your phone may not be able to handle this, if you get stuck on the google logo flash back to another release without the overclock.
What's different about the *.10pcOC.* archives?
This kernel is built with a 10% static board overclock rather than a 5% static board overclock, give it a go if you want.
Builds 207 and onwards are Jelly Bean only
Download link for all builds: http://franconexus.servehttp.com/
Thanks, will give it at try...

Great job thanks for this thread! Can you perhaps create builds without the 5% static board over clock doo daa so people like me who's nexus' don't like it will be able to boot?

This is a known issue with certain phones that arises because they are unable to run the 5% static overclock, the *.doc.* zips in the OP don't include this and they should allow you to boot up as normal.

I just added a freshly compiled doc.512GPU to the OP, I'll add the doc.384GPU one tomorrow.
For reference "doc" in the filename stands for Disabled Overclock, it means the build does not have the 5% static overclock. It does still allow you to apply a CPU overclock.

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.
If you need help, feel free to gtalk me, I don't bite (most of the time): [email protected]
Also, if you feel I have helped, up my rep or even donate

Features
________________________________________________________________________________________________________
Bold = Default
CPU Governors
PegasusQ - A mix of performance and battery life that hotplugs the cpu at low use
Interactive - Boosts frequency based on load put on by the user. Modified to also boost on touch of the screen.
Ondemand - Basic scale on demand governor with no hotplugging
HotplugX - Ondemand modified to hotplug at low use and screen off
Wheatley - Basically ondemand (scales depending on demand) that is modified for performance
Lazy - Basically conservative (scales gradually depending on load) that is modified for performance
Schedulers
SIO - A mix of NOOP and Deadline made for flash memory, like the GNex has
BFQ - Currently experimental. For heavy IO load
CFQ - Attempts to distribute the disk fairly among processes
Deadline - Imposes a deadline on processes to prevent lack of resources
NOOP - Simplest scheduler. Good for flash memory.
CPU Frequencies (MHz)
230, 384, 729, 1030, 1228, 1305, 1420, 1536, 1612, 1728, 1804
GPU Frequencies (MHz)
Set by running: echo # > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
echo 0 = 308MHz
echo 1 = 384
echo 2 = 512
If you don't like using command lines, you can edit the gpu_oc file with es file explorer and change it from 0 to 1 or 2

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.

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.

p_4
Added phase 1 thru 3.1 from old kernel
Bumped to 4.
cherry-picked from AGAT_GB27_kernel. Thanks agat63!

Fixed smartass2 governor.
Added vr-ioscheduler.
p_3
Bumped to phase 3.
Added hypervTNT (with phase 2 and 3 stepping) and smartass2 governors.

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.

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.

ZOHAN makes your hair...emmm Kernel silky smooth .
Well, since it became popular to add something like " for better battery life" I´m renaming my Kernel into Silky Smooth now
There are 2 versions now. First one is the pure kernel and the secound one with Turbo Boost included. (Credits are going to delta-roh)

Created with stability and battery life in mind. Each modification was tested separately, so everytime I added a tweak or a new feature, I tested the new kernel for a couple of days before adding the next one.
So what it has included:
- UV and OC options
- lowered WiFi voltage
- lowered LCD voltage
- slightly lowered standby / deepsleep voltage
- Battery life eXtender
- Fixed 100% battery notification after charger unplug
- 377MB RAM
- ROW scheduler as default scheduler
- Lulzactive Governor as default governor
- tweaked Lulzactive for battery life and smoothness
- added new frequency - 518MHz
- added new frequency - 633MHz
- added new frequency - 902MHz
- Screen Off frequency set to 518 MHz max. in Lulcactive Governor
- Dynamic Read-Ahead
- Dynamic Dirty Page Writeback
- CK3 tweaks (Credits to Con Kolivas) - adapted by Christopher, hurtsky and me
- LowMemoryKiller management of not killable processes - credits to christopher
- with and without Turbo Boost Mod
- no other compilation tweaks just to make the list longer
The max. Screen Off frequency is the maximum frequency your device can clock to while the screen is turned off. It´s a kind of limitation to lower the consumption.
other suggestions:
- enable KSM
- enable 16bit transparency
- greenify your apps
If you follow these suggestions, your ROM should run absolutely smooth without the need for other tweaks.
To use Battery Life eXtender:
Use RootExplorer and go to: '/sys/class/misc/batterylifeextender'. Change the value in 'charging_limit' for example to 90 (default 100). This will set a limit for the capacity to which the battery will be charged. So in this example the battery will be charged to 90%.
----------------------------------------------------
After flashing the kernel whipe your cache and dalvik cache and fix permissions.

- educk (for helping me doing the first steps)
- Christopher83 (for his great commits and tweaks)

honeyx said:
This kernel is a port of the CM9 honeyx 7up kernel. It´s build with Arcos 3.0.83 sources for CM10. There are two versions aviable. The minimalistic and one with all the tweaks listed below. The minimalistic is more close to Arcos kernel. It includes OC/UV options, all the tweaks for battery life, 374MB RAM, the new 518MHz frequency, BLX and Lulzactive governor as default governor with 518MHz screen off frequency. The other one has all the other tweaks included.
Created with stability and battery life in mind. Each modification was tested separately, so everytime I added a tweak or a new feature, I tested the new kernel for a couple of days before adding the next one. This is not the case with this kernel, but these tweaks were already tested in the CM9 kernel.
You will notice my kernels do not offer as much tweaks like other kernels because these are cherry picked to not to affect battery life and stability.
So what it has included:
- added Governors
- UV and OC options
- lowered WiFi voltage
- lowered LCD voltage
- slightly lowered standby / deepsleep voltage
- Battery life eXtender
- Fixed 100% battery notification after charger unplug
- 378MB RAM
- ROW scheduler as default scheduler
- Lulzactive Governor as default governor
- tweaked Lulzactive for battery life and smoothness
- added new frequency - 518MHz
- Screen Off frequency set to 518 MHz max. in Lulcactive Governor
- Dynamic Read-Ahead
- Dynamic Dirty Page Writeback
- Incrased Audio Volume
- new Low Memory Killer for better memory management
- no other compilation tweaks just to make the list longer
I didn´t test this kernel as I´m still using CM9, but made sure the tweaks are ported correctly to this kernel.
The max. Screen Off frequency is the maximum frequency your device can clock to while the screen is turned off. It´s a kind of limitation to lower the consumption.
other suggestions:
- enable KSM
- enable 16bit Dithering
- disable CPU rendering
- greenify your apps
If you follow these suggestions, your ROM should run absolutely smooth without the need for other tweaks.

Good Idea. Madridis kernel has also a modified Ramdisk included if I remember correctly, so this could be the reason.
See first if it works with Arcos stock Kernel and then you can try the minimalistic first.

Well, I flashed CM10 yesterday to check this. Made a pristine installation by whiping and formating everything and used the phone for a while with Arcos stock kernel. Unfortunally the rom didn´t work as good for me as expected. Sometimes the camera stopped working after the phone lasted for a while in deepsleep, so I had to reboot the phone to get it working again. I´ve spend some time outdoors and made some pics of my wife, but when watching the pics in the gallery some of them were displayed to be black. However in the the file explorer they were displayed correctly, but not in the gallery. When I scrolled further the gallery often also simply closed for no reason. Even whiped the thumbnails and all the data for gallery and mediaserver, but this didn´t help either.
I´m not telling you this to tell you this rom is buggy because I know my device is very anal about roms and kernels, just to show you why one and the same thing might work for one but not for the other. I´m pretty sure CM10 is working perfectly for many others but this seems not to be the case with my device.
So well after comming back home I flashed my custom kernel to it and all went well. Just after testing this I decided to revert back to CM9 for the obvious reasons.
Don´t know why, but my phone obviously loves CM9 so I will stick with it.
But the point is. As long CM10 is working well with Arcos stock Kernel for you, there should be also no problems by flashing my kernel over it.
Hi guys, I've been working on a kernel for fun, so I thought I'd share it. The cm10.1 version is based off cm-10.1 branch of team hydra's source. I'm working on a cm10.2 version based off cyanogenmod's cm-10.2 branch. I can't tell you what rom it'll work with, since I mainly use cm10.1, but I'm fairly sure it'll work without problems on other AOSP roms.
Features:
OC/UV to 1600mhz
650ma charging over usb (Yes, it acutally charges when plugged into a computer while in use now..)
UKSM
Always tracking the latest version of Linux 3.0.y
Optimized SHA routines
Dynamic fsync enabled
mmc tweaks
use gnu version of lib/string and memcopy for better performance
Proportional Rate Reduction for TCP
lzo compressed with updated implementation
zram enabled with snappy compression by google
many other low level tweaks cherry-picked from popular kernels for other devices

Seems to be running nicely so far. Oc to 1400 with -50 under volt across the board. Has anyone had any success with lower uv than that? I'm too tired for

The OC/UV is the same used on agat63's kernel and LZ, so you can expect similar results.

Ok...just tested this for a few minutes. Instantly rebooted after flashing....which I really wan't expecting. Thought maybe I had bricked my phone for a sec since I don't have USB access to my phone BUT nope! Booted right up. Played with the gov's...all worked well. 1600 worked just fine. Had to rebuild my scripts for link2sd for ext4 which I expected. Then the bad news......GPS is totally whacked out. Didn't work at all. I used both of my gps apps and not a single sat was found. Other than that it was great! Had to switch back to stock CM till the GPS is fixed because I'm new to Az and don't know my way around yet. Thanks for the work though!
I'll be checking this out, I'm working on building pure vanilla jellybean 4.2.2 so I'll give this a try once the source finishes syncing and I compile it.

I'll look into the GPS issue when I get off work, because I never use it. As far as the reboot, sorry about that, I'll remove it from the next build.
Next order of business: messing with governors isn't really my thing, but are there any that you guys would really like to have in a kernel? IO schedulers as well?

PQ has always been my favorite. I think everything else is awesome. Just went back to Dastin's stock cm kernel and GPS came back. Also, the reboot isn't such a huge deal. I just wasn't expecting it is all. Overall it looks great man
