Kernel builds are currently tested against a stock rom and CM7, while they may work unchanged in other roms, your mileage may vary.
All source code is available on my github (see signature).
Be safe, -ALWAYS- make a backup before flashing!

*Standard Disclaimer: All packaged builds are provided with no guarantees as to their safety. By flashing, you assume any and all potential risks that running a custom kernel might entail.*
*A note to overclockers: If your phone is unstable when running an overclock speed, your particular phone probably can't handle that overclock and you should choose a lower clock.*
All kernel builds mirrored HERE.
*It is generally a good idea to wipe Cache and Dalvik-Cache when flashing a new kernel build to avoid certain problems usually related to Dalvik-Cache*

Changelog:
Revision 1.4.1:
- Updated Ezekeel's Touchkey Dimmer to version 3.0 bugfix 4
- Integrated Ezekeel's Deep Idle mod, current to bugfix 5
- 45,333 rabid naked bunnies were harmed during the making of this kernel
Revision 1.4.0:
- Revert a patch that caused random reboots in certain usage situations
- Added Ezekeel's backlight dimmer sysfs interface (See instructions in second post on how to use)
Revision 1.3.9:
- Return to Deadline as default IO scheduler, using BFQ v2 could cause bugged encounters such as a never ending boot
- Applied kernel tweaks from the recent 2.3.5 OTA (mostly relevant for sprint users)
Revision 1.3.8:
- BFQ updated to BFQv2-r1
- Some build options that may have contributed to random reboots have been modified
Revision 1.3.7:
- Voodoo Sound driver updated to v10
- Testing out tiny rcu
- Touchscreen tweaks are no longer applied by default on boot. Users can still custom tweak touchscreen settings if desired
by editing /system/etc/init.d/98touchscreen and rebooting as before.
Revision 1.3.6:
- Wifi driver changes, rolled back some code that was causing problems
- Added Cyaniris' touchscreen tweaks back in the form of a user customizable sysfs interface (courtesy of work by Cyaniris).
Users can set custom values by editing /system/etc/init.d/98touchscreen , followed by a reboot for the changes to take effect.
Currently the default values are set, users that find the defaults not optimal might want to try some suggested settings by Cyaniris
of 35 for touchthr, and 20 for noisethr.
- Corrected a bug that would have caused reboots and/or other assorted badness when having the phone sleep at a frequency other than 800mhz
(Confession: I was an idiot and forgot to move over this fix from my 2.3.3 kernel trees when making the new kernel trees for 2.3.4, woops!)
Revision 1.3.5:
- Wifi driver updates, bugfixes
- JHash3 Added
- Cpu cache clearing fixes
- New compiler toolchain for builds, using gcc 4.5.2
- Interactive governor adjustments
- IO scheduler set to Deadline, seems to have a nice balance in performance
Revision 1.3.4:
- Remove touchscreen adjustments for now, they were causing problems on some phones.
Touchscreen tweaks will be revisited for a future build
- Add auto group process scheduler for CFS builds
Revision 1.3.3:
- Touchscreen adjustments that may improve touch response
- Update Voodoo Sound driver to version 9
Revision 1.3.2:
- Update BFS builds to BFS404
- Add Simple IO Scheduler and set as default
Revision 1.3.1:
- Smartass screen-off speed adjusted to address unresponsive programs during screen-off
- Smartass adjustments to improve responsiveness
- SLQB slab allocator added to help optimize memory allocation performance
- Some build configuration changes that may improve overall feel
- Ondemand governor up threshold adjusted to improve battery usage while still maintaining responsiveness
Revision 1.3.0.12:
- Adjustments to smartass to improve performance (there is probably still room for improvement)
- Default I/O Scheduler set to CFQ (previously BFQ), this may prove to be more stable in certain situations
- Some adjustments made to the CFS scheduler that may result in a better overall feel to CFS builds
Revision 1.3.0.11:
- Added Smartass Governor
(Not enabled by default, use setcpu or CM's cpu performance
settings to change if you want to try it out)
- Raised voltage cap to 1600mV for crazy people that
want to turn their phone into a reactor ;D
- Set config options in 2.3.4 kernel builds that should enable
NS4G compatibility for our newly arriving sprint friends.
Welcome to club nexus ;D
Revision 1.3.0.10:
- Update kernel base to 2.6.35.13
- Excessive stuttering in apps such as Gun Bros should be resolved
or significantly improved; some problems with memory handling
were introduced in 2.6.35.12 and are resolved in .13
Revision 1.3.0.9:
- The cause of super-lag has been found (Big thanks to twitch153 for helping me test)
- Introducing Universal builds! These universal builds are designed to be flashed on any
non-stock rom of the series marked (ie; Universal 2.3.3)
- Misc other tweaks to the kernel config that may result in an even smoother overall
experience
Revision 1.3.0.8a:
- Fix issue preventing USB debugging (and adb), and sdcard space from working
Revision 1.3.0.8:
- Updated to support the 2.3.4 rom update
- Lots of updates from upstream, including components needed to support
the forthcoming nexus s 4g (yes that means that I will be supporting the ns4g)
- Back to the 2.6.35.12 kernel base, the sdcard tweak has been scaled back
as it appears to have been causing excess lag
- BLN work for i9023 models from akent included (not tested), i9023 users may
find they can now use BLN
Revision 1.3.0.7:
- Revert back to 2.6.35.11 base until I can track down the cause of ridiculous lag in the .12 base
(Not that .11 was a bad performer by any means ;D)
- BFS builds updated to BFS401
- BFS users should find that they have regained their bootanimation
Revision 1.3.0.6:
- Voodoo driver updated to v8
- Custom voltage sysfs interface has changed,
the method used in 1.3.0.4 and 1.3.0.5 is not compatible.
See the guide in the 2nd post for details on the new method.
Revision 1.3.0.5:
- Raised max voltage cap by 50 mV for people who want to try raising the voltage a little bit on 1.4ghz
- More tweaks to try and address instances of "super-lag"
Revision 1.3.0.4:
- Corrected a bug that could cause a slightly higher voltage to be used at certain speeds (resulting in slightly faster battery drain)
- Added a sysfs interface for manipulating voltage levels at various speeds, see 2nd post for details
(read: this allows the possibility of custom under/over volting in realtime)
- Used a different build configuration that may address the occasional "super-lag" that appeared in 1.3.0.3
Revision 1.3.0.3:
- Update kernel base from 2.6.35.11 to 2.6.35.12
- Updated BFS version from BFS 363 to BFS 400 (BFS builds only)
- Raised default read-ahead value from 128 to 2048 (read: sd speed tweak built-in, scripts not necessary)
Revision 1.3.0.2:
- Updated Voodoo Sound driver to version 7
- Fixed a bug that made the sysfs file "scaling_available_freqs" not exist
Programs that must read this file for discovering/controlling available cpu speeds can now do so.
(This also means that CM7 users can set their cpu speeds from the cyanogenmod performance
settings instead of having to use SetCPU)
Revision 1.3.0.1:
- Add initial BLN support (Currently only functional on SAMOLED models [i9020])
Download the BLN control app from the market to use BLN functionality
Revision 1.3.0.0:
- More adjustments to the default colours to try and de-smurf the
previous adjusted defaults while still avoiding "Yellow tint shock"
- Voodoo sound updates (see github commit if you want more details)
- Fixed a bug that caused boot times to take significantly longer than necessary
Revision 1.2.9:
- Voodoo Sound v5 driver update
- Adjust default colours to avoid the initial "Yellow tint shock"
Revision 1.2.8:
- Voodoo Color gamma fix
Revision 1.2.7:
- Voodoo Color driver updates/fixes
Revision 1.2.6:
- Bring panel code up to date with official kernel
- Update Voodoo Color driver to v2
- Release initial cm7 2.3.3 compatible builds
Revision 1.2.5:
- Add 2.3.3 compatible builds
- Incorporate many updates from the newer 2.3.3 kernel sources,
including wifi driver updates, touchscreen updates, drivers for
future SLCD nexus-s variants, and more
(far too many bugfixes and updates to list, review the commit list on my github if you want details)
- Ext4 tweak should be working again in stock builds
Revision 1.2.4:
- Add NFS modules
- Make TUN built-in rather than modular (this may address issues some have had loading the driver)
- Add Voodoo Color
Revision 1.2.3:
- Update kernel base to 2.6.35.11
- Removed the ~56fps cap
- Conservative governor tweaked to perform better for users that choose to use it
- Greater rom compatiblity, particularly with roms that use specialized init scripts
Revision 1.2.2:
- 1.3ghz and 1.4ghz added to the frequency table for overclockers
- Default cpu speed on boot is 1000mhz, use a tool such as SetCPU to overclock
(No doubt I'll get some flack for this, but it's a very bad idea to boot into the max possible overclock when not all phones can tolerate it, so I consider it a necessary evil)
- Interactive Governor added, use a tool such as SetCPU to change to it if you want to try it out (Probably needs a bit of tuning to avoid annihilating battery, we shall see)
- CFS and BFS variants are now available
- Infused with the power of 1000 rabid naked bunnies
Revision 1.2.1:
- Ext4 hack should be working properly now
Revision 1.2:
- Fixed a condition where limiting max speed to 1000 would result in
potential underclocking to 800 (Thanks DebauchedSloth)
- Set hi-res timer to 1000hz
- Gave a little more power to the cpu at 1.2ghz, this may help those
having trouble running at 1.2 be more stable
- Integrated ext4 hack into the ramdisk builds
(ext4 hack is not technically a kernel issue but worth pointing out)
Revision 1.1:
- 1.2ghz overclock *really* works now -Thanks for the help Morfic-
- Cpu policy fix to avoid crashes with SetCPU and screen off profiles
(Courtesy of work by coolbho3000)
Revision 1.0:
- Initial release
- Add BFS scheduler
- Add 1.2ghz overclock
- Add BFQ
- Add Voodoo Sound driver
- Add CIFS support
- Add TUN support
- Update kernel base to 2.6.35.10
Custom Under/Over volting 101:
Code:
**As of 1.3.0.6 the method of custom voltage control has changed, read carefully!**
It is now possible for users to define custom levels of under/over
volting via a new interface in sysfs.
The interface file in sysfs can be found at
/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table
By default, the custom values are all zeroed out, so a
` cat /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table `
will show:
1400mhz: 1450 mV
1300mhz: 1400 mV
1200mhz: 1350 mV
1000mhz: 1250 mV
800mhz: 1200 mV
400mhz: 1050 mV
200mhz: 950 mV
100mhz: 950 mV
Modification of voltages is possible by echoing a string of 8 values
to the sysfs interface via the console, where the order of values
goes left to right from highest frequency affected to lowest.
To adjust the mV for a particular higher or lower than the default,
echo values divisible by 5 like in the following example from an adb shell (this is JUST an example, not guaranteed working values ;D):
` echo "1500 1400 1325 1275 1200 1050 900 850" > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table `
Which has the following effect when examining UV_mV_table:
1400mhz: 1500 mV
1300mhz: 1400 mV
1200mhz: 1325 mV
1000mhz: 1275 mV
800mhz: 1200 mV
400mhz: 1050 mV
200mhz: 900 mV
100mhz: 850 mV
Rom developers, you can conceivably create custom scripts to
apply various under/over volt settings
For reference, these are the default voltages:
Default Frequency Voltage Table:
1400mhz: 1450 mV
1300mhz: 1400 mV
1200mhz: 1350 mV
1000mhz: 1250 mV
800mhz: 1200 mV
400mhz: 1050 mV
200mhz: 950 mV
100mhz: 950 mV
Additionally, there is currently a safety cap of 1600mV for max voltage,
setting a value higher than 1600mV will currently not have an effect greater than 1600mV.
(Read: You can set a value higher than 1600, but it will get dropped to 1600 behind the scenes)
This can be altered for future builds if I get feedback asking for it.
Backlight Dimmer:
Ezekeel said:
Based on the latest BLN version 9, I made some modifications to implement a backlight dimmer which does not need an external program (like cron) to trigger an off-switch.
To activate the dimmer, just echo the dim interval in ms (this is milliseconds; 1000ms = 1s) into /sys/class/misc/backlightnotification/in-kernel-dimmer. If you pass a value of 0, the dimmer will be deactivated.

FAQ:
Code:
Q: I'm getting a "Device or Kernel version not supported" error in Voodoo Control Plus!
A:The error is referring to the generic modules that voodoo control plus comes with to support
kernels that don't already have voodoo built-in (such as a completely stock kernel).
You can safely ignore this error, as voodoo is already built into the kernel.
Q: I'm getting SOD's (Sleep of Death) when undervolting!
A: You are probably undervolting too far
Q: OMG I'm getting a black screen (no boot animation) when booting a 2.3.3-based rom!
A: This tends to happen mostly on BFS builds, though it *can* occur on cfs builds (and even on the
stock kernel). The exact cause of this glitch is not known at this time, however, it is purely cosmetic.
You will notice that the bottom buttons are lit, and if you were to run adb logcat, you will see that the
phone is active. The phone is actually booting, just be patient.
Q: What are BFS and CFS?
A: They are task schedulers (they determine what processes get cpu time, how much, etc).
CFS (Completely Fair Scheduler) is the default scheduler in the official mainline kernel. It's a tried, tested, stable scheduler.
BFS (Brain **** Scheduler) is a third party scheduler written by Con Kolivas that must be patched into the kernel, and replaces the CFS scheduler. It tends to be faster in certain tasks, and is usually pretty stable, but sometimes there can be performance quirks.
Downloading and Testing! THx
Is using setCPU advised?
EDIT: Removed to avoid confusion as the info previously contained in this post is now outdated and invalid.
Someone give a shout out if this works with cm! Haven't got time to test it myself today. And thanks for your work!

Thanks
Just a heads up
Doesn't work with CyanogenMod 7 nightly
netarchy said:
SetCPU is not necessary.
You're free to use it of course, just remember that the NS idles at 800mhz, so if you use a screen off profile, take that into account.

To make it cm7 compatible he can split_bootimg the cm7 kernel.

Koush's anykernel can serve that purpose. It splits out the ramdisk from the current boot on the phone and combines it with the zImage of the new kernel (meaning no having to manually repack ramdisks to make various rom-compatible builds), then flashes the new boot image.
Once I have it playing nice with the NS I'll be able to post universal builds. One of the many things on my todo list ;D
Nice. Loved your work on my evo and stoked to try it here. More kernel devs means more choice and hopefully a richer collaborative spirit

[KERNEL] [2.6.29.6] [Flashable-.zip] [LAGFIX][BFQ][Oc][Uv] #3 "Patches 'O Klick"
So after countless hours of failure, I finally found my issue. It was an embarrassing one, but O well. What we have here is a fully stable kernel for the Vibrant. I have spent many hours on this and have been running it on my vibrant for some time now. Be sure to read the changelog for full info. At 1.2 Ghz I was getting MFLOPS scores pushing 10 MFLOPS! Performance is surely nice on this one. Another thing to note is the undervolting on my kernel. This will give optimal battery life for users. So, please enjoy, and post and errors with a logcat
This is compiled for the stock ROM. It will work on FrankenTwiz, Bionix, and many ROMs. Let me know what ROMs you try it on, and what ones it works best with.

This would be my first time using an oc/uv kernel. I know to get the oc, I have to go into setcpu and put the scaling to conservative, which I've already done. Ran quadrant, and got a score of 2790!

ok ima give it a shot and report back
This is gonna sound noob but here it goes. I've never done research on what exactly kernels are and this is all new to me.
This new kernel I can flash like Rom will over clock my device to 1.2ghz or will it give me the option to? Can overclocking hurt my device in the long run?
Does this come with tools to over and underclock when I need to?
Any other info would be great. I'm on Eugene Franklin twis v2, no voodoo or lagfix yet.
Any other info would be awesome.

Installed, booted fast. Thanks for your hard work.
Good to see you back, King! Do you think this will work ok on Eugene's Hybrid R3? Also, I know some Vibrants (like mine) didn't like jacs OC kernel. Same issues here, or did the undervoltage kernel fix it?

Kernel builds are currently tested against a stock rom, while they may work unchanged in other roms, your mileage may vary.
All source code is available on my github (see signature).
Be safe, -ALWAYS- make a backup before flashing!

*Standard Disclaimer: All packaged builds are provided with no guarantees as to their safety. By flashing, you assume any and all potential risks that running a custom kernel might entail.*
*A note to overclockers: If your phone is unstable when running an overclock speed, your particular phone probably can't handle that overclock and you should choose a lower clock.*

FAQ:
Code:
Q: I'm getting a "Device or Kernel version not supported" error in Voodoo Control Plus!
A:The error is referring to the generic modules that voodoo control plus comes with to support
kernels that don't already have voodoo built-in (such as a completely stock kernel).
You can safely ignore this error, as voodoo is already built into the kernel.
Q: I'm getting SOD's (Sleep of Death) when undervolting!
A: You are probably undervolting too far
.
lol when I do this my thread gets deleted/moved/renamed by the devs. I suggest you hurry
yehhhs...netarchy is coming back...
i hope so it make change for nexus ICS..
Good to see you back dude.
Nice! Thx

Welcome back most awaited kernel for me. Downloading now.
Flashed it. No problems so far.
can you please up the available voltage range to 1475 mV? my device needs at least 1400 to handle 1.3ghz.
right now it's capped to 1350 for me in setcpu.

, cap was supposed to be 1600, woops! I'll fix that in the next build.
Welcome back! Just like the good old days.
Beamed from my Nexus S
YES NETARCHY FOR ICS
Now I can really start playing with ICS.
Will be LiveOC and Deep Idle suppport?
any performance tweak in this kernel?
That weird dim-green tint thing when turning the screen on and off is back. I can't seem to get rid of it like I did in GB.
welcome back netarchy
Yay Netarchy is back!
Nuked from Nexus S with ICS using XDA Premium app
my first impression is that this one is blazing fast. No delays whatsoever. Good job so far!
will keep it for a while and see how the stability works out. is it a bfs or cfs kernel by the way?
NS4G please
fps kernel by dr4go
This kernel is based on the newly released LG v20Q sources, but also includes every (still) needed fix from imperticus' NeoBlaze kernel. It should work on both Froyo and Gingerbread stock and MoDaCo based ROMs. It won't work with CyanogenMod based ROMs.
Prerequisites:
For the SWAP Enabler you need at least 384MB of free disk space on your /data/ partition. And because the swap enabler just triggers the creation of a swapfile it would be best if the data partition wouldn't be too full when executing it (fragmentation will decrease the swap performance by a whole lot!)
Features:
- EXT2/3/4 built in
- NTFS R/W built in
- OC/UV support, overclocking up to 1552MHz [based on cpasjuste] - I recommend SetCPU (http://forum.xda-developers.com/showthread.php?t=505419)
- SDRAM, VDE and GPU overclock [morfic]
- Voodoo Sound [supercurio]
- VR I/O scheduler
- BFQ I/O scheduler (default)
- SLQB memory allocator
- CIFS, TUN
- SWAP support (including swap notify patch for people who want to play around with compcache)

INSTALLATION
1. Remove "boot settings" from Pimp My Cpu to reset to default values
2. Reboot into CWM (v5.0.2.7-r2 recommended)
3. Install zip file from SDCARD
4. Reboot
Kernel sources: Github
Personal note: Although I've already been built a lot of kernels (for the HTC Desire HD and also the LG Optimus 2X) I've never released them to public. And I mainly decided to do it, because I'm really really unsatisfied by the performance of this device. Imho it could and should perform a lot better. Join me if you would like to be part of this adventure.
And to conclude with imperticus words: Please also don't forget the 'Thanks button'.

FAQ
1. Does fps stand for frames per second?
No, it doesn't. And I will never ever release this information to anyone here. Sorry folks.
2. What is the difference between the normal and the safe version?
Only the installer. If you're stuck when booting, please try the _safe version. Otherwise it is the same kernel.
3. ...more to follow...
It's a great news to have a new kernel to try!
Edit:
ROM:Gueste2x_v2.1(base on v20e&v20m)
1.After 3 times test, quadrant score is about 2800 at 1Ghz.(HP SR1 is about 3300)
2.Andrev OC can work. I really like Myrt's apps to set UV&OC.
installed kernel on stock gingerbread rom.
got a quadrant score of 5700+ at OC 1.2 ghz (VR I/O scheduler)
changed I/O scheduler to BFQ and my score jumped to 6000+
dr4go,
Will you add swap support to your kernel? Because this is really great feature for our low memory device )
Fast. Smooth. Thanks!
Sent from my LG-P990 using XDA App
How come these kernels doesn't work with both CM7 and stock (like MCR) based ROMs? Isn't it possible to fix it? Modles? Kernel version? Too much patches provided by LG?
Remember HTC Hero development back in the days; almost all kernels worked independent on ROM. It was an exception (more or less) if the kernel didn't work with a specific ROM.
Looks like a great kernel, but won't flash a stock based ROM over CM.
What about battery life?

Thanks, that is exactly the information I need to improve the kernel. During HTC Desire HD days, there was no better scheduler than the VR I/O scheduler.
Could you also share your results you get with the Anticipatory-, NoOp- and Deadline-I/O scheduler? That way I could select the best one of those.
Thank you in advance.

Noted. Imo you are right, that it would be a great feature for the LG Optimus P990.
Still a lot on my todo list... I already wanted to release it a few days back (as you may have noted I made the last commit on December 12th - since then I'm using it on my device.
Lastly... regarding the todo list: it's done when it's done - and as always: No information released to public before a new kernel it's out.
Stay tuned folks.

Don't get me wrong: I never had CM installed on any of my previous Android devices. My kernel may work on CM, but honestly... I have no clue.
Yes I've also wanted to try CM once, but as you know... you don't have time for everything.
If you are willing to test it, just flash my kernel (but leave also any other working CM kernel on your SDCARD just in case it doesn't boot anymore) and if you do so... please report back... also what works or what doesn't work...
Thanks in advance,
dr4go
I dealt want to try this kernel buy I do not want to f**k up my phone because it is very good with v20o and rock stable.
is it possible to post a stock kernel so I can return without a flash?
thanks

This is your current kernel you have.
To restore it, there are two possibilities:
1) Copy it to your sdcard and flash it inside a root terminal using the commands:
Code:
dd if=/dev/zero of=/dev/block/mmcblk0p5
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p5
2) Copy the boot.img file inside your nvflash folder, and execute:
Code:
nvflash --bl fastboot.bin --download 10 boot.img

tnx ..i made a nandbackup with CWM from my current rom and now a have flashed your kernel so if anything goes wrong I can go back
I will test this kernel for a couple of days for stability and battery use.
what's with the "windowsmgr.max_events_per_sec 120 " ??
LG 2X lcd screen has a refreshrate of 72hz so anything higher than 72 fps (120) could cause tearing in animations (?)
thanks for your effort and time

Max_events_per_sec sets OS(software opengl related params) related frames. While actual hw fps is setted in tegra frame buffer kernel driver. Increasing refresh rate at HW level(at kernel level) gives fake higher 2d (as benchmarking software read hw refresh rate to judge 2D),Infact worsen performance and in a long run it damages LCD Controllers and can be dangerous Actual supported refresh rate is 60hz for mobile QVGA and HVGA and you may find 60-62 with other company except LG.

Disabled a lot of debugging
1.2
Implemented Dynamic Filesync and enabled by default
Proportional Rate Reduction for TCP

Enabled Compaction and linked it to LowMemoryKiller
Updated Deadline(now it's better than ROW)
Changed kernel compressor/decompressor from GZIP to the much faster LZ4.
Writeback tweaks from Linus Torvalds
Added TCP congestion algorithms: Hybla, Westwood, Highspeed-TCP. Default is Hybla because in tests, performed better than the rest.
1.3

New 652 MHz undervolted frequency
CPU Unaligned Access (much faster booting time because of better kernel decompression)
Buffer values updated from Samsung original sources(Triple Buffering, Camera)
SmartassH3 and KSM parameters tweaked for better battery life
1.5
CPU clocks rework

Recalculated Frame Buffer Size for Triple Buffering
Clean-up(remove deprecated CPU governors)
1.6
Add newest Adaptive RED Net Scheduler from 3.4 kernel and make it default.
Replace Snappy Compression with LZ4 Compressor(this is the fastest compressor on the market)

Fixed the Deep Sleep states verification for scaling
Added GPU Control Driver
Added Sampling Down Momentum for dinamically changing the factor for scaling down
Updated OnDemand governor (it's pretty good at the moment)
Remove Badass and Lazy as they were deprecated
Link BoostPulse to the touchscreen driver for SmartassH3 and OnDemand
Optimize the CPU clock structure for WheatleyPlus

Introduce Timer Slack Controller (aka Timer Coalescing, explanation below)
Deep Sleep tweaks
Backport OOM Killing algorithm from 3.8 kernel
Backport LowMemoryKiller and Timed GPIO drivers from 3.8 kernel

Android Binder update
CFS kernel scheduler optimizations
GPU driver optimizations and code cleanup
Make sure that the GPU turns off when the screen is off
Make the sleep states transitions faster
1.9.1
Finetune WheatleyPlus for better responsiveness

Fixed graphical glitches(hopefully)
1.9.2
Every bug fixed
Removed WheatleyPlus
Updated Interactive governor to the latest version from 3.8 sources
Add Dynamic Interactive governor (98% the same as Interactive, but it dynamically changes its parameters according to the load)
Dynamic PLL Overclock
Further undervolt until 768 MHz (the latter allows us to do this without losing performance)
Predefine minfree and adj values
Fully functional App Whitelist (example script here)
Forced unaligned access
Fast Charge (use this to enable it: FastCharge.apk - 1.29 MB) [Disconnect USB Cable - Turn ON - Connect USB Cable]
Timer Slack Controller: (this is a copy-paste from boype's thread)
What does the timer slack feature do?
Timer slacking aims to synchronize applications' and processes' CPU requests. The goal is to wake up the CPU less often in oder to save battery. What you need to know here is the following: waking the CPU up and putting it back to sleep again consumes power. Imagine that four apps wake the CPU up four times each in one second. While without timer slacking the CPU would be woken up 16 times, it is desirable to coordinate the wakeups. If done right, the CPU would wake up less often, effectively allowing power savings and longer sleep periods. This is what timer slacking does.
I have activated timer slacking only for background applications, so that everything else stays as responsive as you know it.
Apple has recently introduced this feature under the name 'timer coalescing' with their Mac OSX Maverick (link).
More information: How Apple does timer slacking ('Timer coalescing') (Scroll a little down to the diagrams)
LZ4 Compressor:
LZ4 is a very fast compressor, based on well-known
LZ77 (Lempel-Ziv) algorithm. Originally a fork from LZP2, it provides
better compression ratio for text files and reaches impressive decompression
speed, in the range and beyond 1GB/s per core (!), especially for binary files.
These speeds are scalable with multi-threading modes, quickly reaching
RAM speed limits on multi-core systems.
ROW I/O scheduler:
The ROW scheduling algorithm will be used in mobile devices as default
block layer IO scheduling algorithm. ROW stands for "READ Over WRITE" which
is the main requests dispatch policy of this algorithm.
The ROW IO scheduler was developed with the mobile devices needs in mind.
In mobile devices we favor user experience upon everything else, thus we want
to give READ IO requests as much priority as possible. The main idea of the ROW
scheduling policy is just that: - If there are READ requests in pipe - dispatch them,
while write starvation is considered.

Various tweaks
Script for adding apps to LowMemoryKiller's whitelist:Whitelist
(you have to edit it to add your own apps, then move it to init.d and set correct permissions. right now you can only add one app, I'll fix this in the next version)
Script to enable zRam with optimized disksize for our Mini: View attachment zRamV2.zip (flashable zip) [UPDATED]
Jeeko's PureAudio fixed for CM10.1 and AOKP: View attachment PureAudio__1.0_-_STUDIO.zip [ Please thank Jeeko for this awesome mod. ]
NOTE: This version of PureAudio is compatible with absolutely any equalizer or player.
If you have Titanium Backup installed, in the menu you'll find an option named "Integrate sys Dalvik into ROM". Use it.
This is something like odexing your system, but keeps the classes.dex files inside the apps. Don't worry if you don't have a lot of system space, Titanium will odex as much as it can until the free space runs out.
TIP: So in latest version of CrossBreeder, the OP added some system tweaking which interferes with our kernel. So I edited those parts to match our settings and device limits.
If anyone wants to install CrossBreeder:
-First uninstall by flashing this file: CrossBreeder_Uninstall_7.2.13.zip - 943.12 KB
-Then install this custom version: CrossBreeder_7.2.13-Badass.zip - 1.59 MB

LOL, forgot to tell you, they done it in only 5 hours ! I'm proud how fast they work. BTW, kernel didn't work for GB, i'm stuck at Bootsplash
Sorry, I forgot to mention the compatible roms
The kernel is for 4.2.2 and that includes CM10.1, AOSPA, PAC and AOKP.
Yes, changing the ramdisk would make it compatible with every rom based on 4.0+ .
I mentioned CyanMobile because that is the name of the maintainer of the repository on github. I think it is based on the kernel used by squadzone for CyanMobile because it has traces of those weird governors (lulzactive, darkside, smoothass etc.)

Upload your boot.img here and I will change it.
And none of those would interfere with the kernel.
In the meantime, I will upload a script to enable zRam, you might wanna check it out after you flash the kernel.

Man, I'm already impressed with A_U's Kernel , and wanna test yours. Here's the boot.img (I think it's from cm9 but it's still ICS, same thing, right?) Thanks BTW.
Tested and everything work like a charm to restart, phone got restart and stay on boot animation
Edit .: manual reboot make phone boot

Hello bro...!! i am uploading stock Android AOSP ICS kernel built by Paul.... i.e. not from any modded roms based on dat...
thanks a ton.. and finally I am happie that even our device is seeing some new kernels.. i always wondered why almost all devices have so many kernels and ours not as dat much..
plz change the ramdisk... anytime your free. no ETA's right now m using ur undervolted AU kernel for aosp ics.. wanna say this.. no deep sleep in my phone... bt still i get insane battery backup now... like 8 hrs... thats too much THANKS
i seriously dont want to change from TW UX V5 to 4.2.2... .
I would say that the kernel is very good, but I think that it could add things known to speed mod kernel (no speed mod for galaxy mini). Please Alin.p kernel to develop even better and allowed the acceleration of 10.1 cm (speed)

Here is the kernel: View attachment BadassKernel-ICS.zip
You have the same ramdisk so this should be compatible for both of you.
Deep sleep is working with this kernel. What your problem might be: constant wakelocks from badly written apps (use Wakelock Detector to check that) or min frequency of the CPU set too high. 122-600 MHz with SmartassV2 and Deadline I/O and you won't have any problem.

Thanks for telling me about SpeedMod. I'm looking into it and see what I can port.
As for the acceleration, are you talking about Hardware Acceleration? Because this is already working in this kernel.
can u upload/commit ur sources? i would like to see some stuff..thanks.

No bro.. my problem is with Power button.. Itz not working.. hence my deep sleep is not working in any rom at all...
itz definitely not the kernel prob. I am sure.. and all these days i used to get worst battery backup.. this hinders me from using 4.2.2 rom for a long time.
Any way now thankz to you and A_U combined efforts with this kernel I feel like a BEAST and with TW UX v5.. Man my phone is Legendary now.. I love it more than ever...!! Thankz a lot.. and yeah.. already pressd THANKZ button a lot....

It is right here: https://github.com/alin23/android_kernel_samsung_msm7x27
I'll update the OP in a few hours with the source and a new update.
The first commits are really messy because I didn't know much about git.

Well, there are applications that can put your device to sleep by touching the overlay or the shortcut on the homescreen. It is exactly the same as pressing the power button.
Here is one of the most popular: https://play.google.com/store/apps/details?id=com.jiubang.goscreenlock.plugin.lockscreen
Introduction
The idea for creating this kernel came up around a year ago, during early LP custom ROM builds. I thought it would be a nice idea to fork the most advanced kernel at the time, EvoMix, developed by our renowned Olivier, Joe (SuperHanns) and Alex, and add to it the latest upstream 3.4 patches as well as mix its features with another good kernel, KMA.
After that experiment turned out not so bad, me and fellow xda user BrateloSlava got an idea to continue developing that mixed kernel with our own cherry-picks from the best kernels available for various devices, and use it in my builds of RR and later GZR Tesla ROM.
Now, one year later, I continued the development that BrateloSlava did on the kernel for the last months for my Tesla and Validus ROMs, and I thought it would be a nice idea to extend this kernel's availability to the users of all custom ROMs around at the moment.
So, here is Airless Kernel for Xperia Z, compatible with all CM/AOSP based Marshmallow ROMs.
Features:
CPU
- Governors: ondemand, interactive, performance, intellimm, yankactive, yankdemand, zzmoove, barry_allen
- Multicore Power Saving - tries to group tasks into the least cores possible
- Schedule workqueues on awake CPUs
- CPU Frequency underclock (192 MHz) and overclock (1.7 GHz) capability
- Voltage regulation
Thermal management
- Simplified and efficient thermal driver
- Flexible ramp threshold temperature
GPU
- Governors: simple, ondemand, performance
- 27 MHz idle frequency for ideal power saving
- Overclocked to 487 MHz
Sound
- Faux Sound Control allowing amplified speaker, headphones and microphones volume
Misc
- RGB subtractive color control
- I/O Schedulers: sioplus, bfq, fiops, zen, row, deadline, noop
- Dynamic FSYNC
- Kernel Samepage Merging
- ARM Auto Hotplug (mpdecision replacement) - no tunables
- Gentle Fair Sleepers
- PM: Power Suspend as a replacement to Early Suspend
- TCP congestion protocols: westwood, highspeed, cubic, reno
- Disabling of some well known wakelocks (e.g. msm_hsic_host)
- Double Tap to Wake
- Fast Charge
- Vibration Strength control
- Compiled with latest UBER 5.x GCC toolchain
- Latest upstream patches: 3.4.112
- Many build flag optimizations (graphite, Ofast)
Download
Latest version (20160901)
Installation:
- Make sure you're running a CM or AOSP-based Marshmallow ROM (Resurrection Remix, AOKP, etc..)
- Flash the zip in TWRP 3.0 (tested, recommended) or other compatible recovery
- Reboot

Version Information
Status: Stable
Stable Release Date: 2016-09-01
Created 2016-05-09

Tunables for reducing minimal brightness:
Code:
### Reduce backlight brightness
## to revert to default - enter 0
echo "8" > /sys/module/leds_lm3533_ng/parameters/lm3533_bl_reduction;
## values of brightness, lower than lm3533_bl_brightness_min, are being decreased by lm3533_bl_reduction
echo "30" > /sys/module/leds_lm3533_ng/parameters/lm3533_bl_brightness_min;
Important: disable mpdecision in Kernel Adiutor. This kernel has its own hotplugging driver.
Oh god thanks, i can't wait to try this kernel :fingers-crossed:

How do I make make use/activate it?
Also, could you please add pre-tuned Gamma settings like Tommy-Geenexus did for his Zombie Kernel? As you are well aware, the XZ screen by default is very dull and could do with extra constract/saturation.
Thanks
Edit--
After flashing this kernel, it feels a bit sluggish as if it's saving too much power.
Will install it now. Can you add lower brightness like in zombie kernel?
There is already lower brightness, you'll just need to set up a init.d script with these lines:
Code:
### Reduce backlight brightness
## to revert to default - enter 0
echo "8" > /sys/module/leds_lm3533_ng/parameters/lm3533_bl_reduction;
## values of brightness, lower than lm3533_bl_brightness_min, are being decreased by lm3533_bl_reduction
echo "30" > /sys/module/leds_lm3533_ng/parameters/lm3533_bl_brightness_min;
I may add pre-tuned gamma for next builds, until then use the RGB control in Kernel Adiutor -> Screen.
If you feel it's slow, just tune some parameters in kernel adiutor, like up_threshold in the cpu governor, disable multicore power saving etc. Also check if there's a stuck throttled cpu max frequency, that can happen sometimes if it throttles during boot.
Anyway for me it's not sluggish at all, I wouldn't have published it if it was.
Also I'd like to kindly remind all to use the devdb feature and at least provide logs for any problems you encounter and state the ROM you use and its version.
Devs are not psychic to know what's going on with your usage.

Sorry, I'm not planning to make blind builds.
If there's any dev that owns odin and is willing to do it, he can freely rebuild my kernel for it, just keep the source references and filename.

Nice to see a Custom Kernel for our old phone . Thank you for your hard work, it really made a difference in speed on my phone running the latest version of RR.
As a request, can you add to the GPU the 400Mhz option? I mean I'm not fond of overclocking, and prefer to use the stock speed regarding the CPU and the GPU.

Unfortunately an additional frequency cannot be added due to known problems with frequency decisions of the driver when it's added, so it would have to be fully non-overclocked if we want to have 400 MHz.
I can assure you that there's no significant battery drain with 487 MHz nor any other issue, but if you totally insist on having stock max frequency, I can provide an optional version of the kernel with GPU OC disabled.

No need to do this. I will just downclock to 320Mhz, since the difference in performance isn't that big to affect my daily use. Anyway you are awesome for making this offer.:good: You don't see this kind of thing everyday.
Sd card corrupted error after flash((
How to fix?(
I don't want to format it
I tried sd card on computer and it worked...
Is it safe for those who are on customized rom??
