Info about some mods:
1.4Ghz Overclock + UV. Kept Qualcomm's frequencies table as proved to have less battery drain for some reason.
The undervoltaging is max -50mV on most frequencies, as to avoid error corrections from low voltage (errors in calculations increases drain a lot) and also to avoid cpu halts. Needs further investigating for lower values.
Now using aire's values, the best for battery for over a year.
11mb ram freed from camera and adsp pmem. This came from many tests that showed that when taking 8mp pictures, 720p video (w/ or w/o stabilizer), playing 720p video with hw decoding and hw audio decoding audio, the used pmem was max 42MB for camera pmem and 6MB for adsp. Can be freed 7-8Mb more but didnt do it for stability reasons under multimedia multitasking.
That also shows us that the stabilizer lag in camera doesn't come from the pmems. I'll try to check the camera sources and see if it's driver related.
If you find anything strange with anything that use the camera or the DSP tell me and please provide logcat logs.
Triple Buffering. At last some JB goodies to us using stock. This gives great UI and game Frame rates (tested). It uses the normal mode (as we don't have the vsync sync pulse like JB, which also auto disables it when not needed), and that means that it doesn't introduces slight lag to input. In games if you see something strange though please reply in this thread.
Random Entropy Generator. Fixes and tweaks to random generator. And also to binfmt_elf, no more entropy depletion through using shell, scripts and generally any binary. Say no to blocking random, and enjoy a smoother UI.
Now with frandom for 50x more performance.
Governors/IO scheds. No bloating here. Kept only the best for battery and performance.
The default ones are the highly optimized. If you have some tweaks for all schedulers that will increase battery and performance (always in balance), don't hesitate to tell me.
Key reset. You can reboot your phone when kernel halts or something brought your phone to its knees by pressing
Power + Home for 5s. Don't do it just for restarting it fast! This does not good to your filesystem because they can't sync,
so you can lose changes made the last seconds. Also after initiating it you don't have to press both buttons for the remaining 4s.
In 2.8 the combination is Power + Home + Volume Up for 5s.
Twrp and Cwm differences. TWRP and CWM are both recovery apps but use different apis.
CWM use nandroid backup and TWRP uses it's own.
CWM uses and old recovery API (v2) and TWRP use the newest recovery API 3
That means that you can't use a backup made with cwm in twrp, and vice versa.
In TWRP, some flashable zip will not work, until they have a newer update-binary (that supports API 3).
(That's the one provided by Team Win: update-binary-3)
If you want other info, again write here. And last but not least the kernel version number 0.8a doesn't mean that's beta. The kernel right now is highly optimized and working. The version just means that I'll try many things more to make our phone better.
Thanks:
wedgess for his great Lupus kernel sources.
aire and vdsirotkin for their great kernels that i used for many months at both GB and ICS.
DooMLoRD Well you all know why
thomas1991_12 and championswimmer for help and twrp binary accordingly
And to all Freexperia Project members for their great patches and fixes to our phones.

DISCLAIMER for sharing outside xda:
It got to my attention that the kernel is shared in many boards outside xda
and especially in many Asian ones. It's fine to make a complete copy of OP and changelog,
I don't mind, but you have to provide a link to this thread.
Also, the most important, please use my links for kernel binaries. If you don't do this, I can't see usage stats of my kernel.
That's why I use mediafire. It's fast, supports multiple connections, no wait time and is usable in every country.
Downloads and Sources:
Main Version:
CTCaer Kernel v2.8 1.4GHz + UV
or
CTCaer Kernel 2.8.2 UKSM special version
The special version may not work for you, cause of lower voltages. After 20 sept, i'll do proper releases.
Vdd Version:
DISCLAIMER: I will not provide help on reboots and bootloops on 1.6GHz + VDD control version.
It's here for people that need 1.6ghz and voltage control only. Default speed is 1.0Ghz.
CTCaer Kernel v2.8 1.6GHz + VDD control
If you want to use usb storage, ntfs and more you can flash these modules (if not, they are optional):
Modules for CIFS, NTFS, FUSE and USB Storage v2 ** Updated **
The updated modules bring: Updated cifs,fuse,ntfs,usb-storage and adds nls_utf8 for Unicode support, plus oprofile for people that want debugging.
CTCaer Kernel needs stock wifi modules. If you changed them, flash this:
Stock .13 WiFi modules
If you came from a kernel that you had to flash custom modules, use the flash zip above to have the stock ones again.
Some kernels, like Lupus, change the modules on their own, by just flashing the kernel and powering on the phone.
The original with Lupus are moved in /system/lib/modules.old.
Info for going back from Lupus
Many thanks @arcatarc for providing the flashable update zip.

Changelog:
Older:
v0.8a:
*Initial Release.
v0.9 (renamed to v2):
*Added 1.6Ghz (UVed)
*Removed Ondemand
*Added OndemandX cpu scheduler
*Added CFQ i/o scheduler
*Removed autoroot
*Changed ro.secure to 0 for rooted ADB on default
*More ram (because of ramdisk's reduced size)
*Fixed Kernel Samepage Merging startup.
*Reduced freq to 1Ghz for kernel booting (to avoid 1.6ghz's drain). Comes back to 1.4Ghz for at bootanimation.
*Some more ramdisk changes
v2.5:
*New logo. SE strikes back with energy logo
*Deep undervolting. Thanks to Intuki for providing aire's values
*Fixes to binfmt_elf. No more random entropy depleting through using cat, ls and well every binary and script.
*Random entropy generator tweaks. I scream more UI smoothness
*Enabled cpu group scheduling
*Better pmem (updated to 2.6.35.x. For full changelog: pmem patch)
*Removed unused modules and some non-usefull debugging for a lighter Kernel
*Fixes to memory leaks on the networking side
*Fixes to android binder
*Usb network tethering support
*Added ipsec tunneling support
*Fix to cpufreq. Now you can see available frequencies through /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
*Removed KSM because after so many days nothing in our phone calls it
*Tweaks to ramdisk for faster boot
v2.51:
*Reverted pmem code to stock to fix broken adsp for videos. Sorry about that :/
*Known bug on 2.50-.51: Unstable 1.6ghz because of low voltage.
v2.52:
*Added 1.5ghz and stabilised 1.6ghz more
*Changed PATH variable at boot end so busybox is not taken from /system/bin or xbin
*Increased 720p vidc default input buffer for smoother video playback
*Fix a race in pid generation that causes pids to be reusedimmediately
MIUI compatibility:
*Added MIUI shelld service (stock based roms are not affected by this), thanks to stillka
*Reverted binder patches
v2.6:
*Split kernel to 2 versions:
1.4GHz with Undevolting
1.6GHz with Vdd (voltage) control
*More Undervolting to lower frequencies for even better battery for main version. (3 days test showed 1% per 7hours with gsm+wifi on+widget updating every 1 hour)
*Stabilized higher frequencies.
*frandom implementation inside kernel. No need for module. It's 10-50 times faster than random/urandom
Replaced random and urandom with frandom and erandom. No need for apps to do that and it's done at boot so no app or process use the old ones.
(For ramdisk modders: the script is in /sbin/bootrec. You need it for frandom replacement before android boots.)
*Enabled bfq i/o scheduler cgroup
*Fixed PATH variable for good. Now it will report the right busybox in scripts and apps that can't use their own path.
*Tweaked cgroup values for background apps and more
*Enabled memory suspend deep power down. (This will do nothing for roms that can't use it, or without a script calling it)
*Enabled scheduler tunables (like sched_latency_ns, sched_wakeup_granularity_ns and more). Here's a good read about them: sysctl scheduler tunables
Tuning them will provide some more boost to your ray. Have in mind results are different from system to system and different workloads.
v2.7:
*Default scheduler is now SIO for nand and sd
*More total ram (4MB)
*Tweaks and fixes to msm_fb and mdp, for optimized and faster rendering plus less ram usage.
*Optimizations in memory management
*Updated LMK to the latest aprl-2013 version and added some tweaks
*Updated to a more optimized Compaction
*Optimizations to RCUTiny
*Optimized smartassv2 and added Boost pulse
*Added ROW scheduler, thanks to @kast
Experimental!
(Also some optimizations from the k3.4 version are missing for now)
Any benchmark on SIO vs ROW are welcomed.
*Performance optimisations on SIO and Deadline i/o schedulers
*Updated CFQ i/o scheduler
*Reordered functions in input driver for faster touch responce
*Removed Superbad and Lulzactive to lessen the kernel threads and free ram
*Kernel decompressor optimazations to Lzo
*Added Reset by pressing Power+Home keys for 5s
Only use it when you have to. (example: kernel halt) Don't make it your new reboot way!
*Made vibrator worqueue's priority higher to lessen the lag in big cpu load
*Added compact mem per node
*Fixed performance calculation in vidc (video codec)
*Enable Fsync
*Protect a proccess from killed by LMK far too many times
*Fix to suspend power management
*Fixed init.d support not working when having install-recovery.sh for int2ext and other scripts
*And more performance and memory optimizations..

I'll consider it. I'll maybe add one with 1.6ghz or with one capped at boot at 1.4ghz. Will see
How i wish their is interactiveX & CFQ. ehehe
From the features it seem a really good kernel(i like the fact it use stock wifi modules too),tnx,but i have some questions:
1)It is undervolt embedded in kernel?
2)Can you make a version without autoroot (or can i modify your ramdisk to use in my rom)?
Tnx in advance and keep the good workin..
Sweet candy, baby! Sounds AWESOME! Flaaaashing immediately! OMG, LOL!
Triple Buffering=project butter?
OK flashed, looks promising. I am on Zelly Cream and superuser doesn't start. What now?
EDIT: Cleaned dalvik, cache, fix permissions, cleared data on superuser app. SuperSU also not able to update binary. Sorry if it's a stupid situation.

It was in my intentions to add CFQ but forgot to re add the kernel flag. Have in mind that cfq maybe is one of the most configurable io scheds but bfq does a better job in fairness (because it's an improved cfq).
As for interactiveX I'll review it.

1) Yep to avoid reboot problems. (even in stock voltages and configurable vdd for example, my ray reboots.)
I'm open though to suggestions about levels. In the next days I'll play a little with the current_now and try some new voltages until i find the
sweet spots before the error corrections begin. Also if for example 750mV has the same drain with 800mV I will keep the 800 one for stability. No need for extreme undervoltaging.
2)Well to be true I didnt wanted to included but many ppl need that feature from the kernel. If will remove it? Dont know yet.
But for sure you can edit the ramdisk. Just comment out the autoroot service in init.rc or delete the autoroot.sh in /sbin.

Yep. Well almost. It's what the project butter is based off.
Until now (testing it for 8days) it does a good job and the UI feels a looot better.
Need some tests from games though. I heard that triple buffering made some glitches in xperia T JB. If it's kernel related maybe i can add the patch to our sources.

Well it's not. The superuser is the latest 3.2 and does not have update ability (the button that says update is cosmetic and version informative). The autoroot script is copying the superuser and the su. You are ready to go.
Also no need for wipes. If something doesn't work it has nothing to do with caches.

THIS THREAD HAS BEEN RETIRED | THIS IS FOR ANDROID: 2.3.4, 2.3.5, 2.3.6, 2.3.7
Developer: Gokhanmoral | Donate | Website | Original ThreadDownload: SiyahKernel v2.6.14 | ZIP | TARExTweaks - The Kernel Tweaker
2.6.14 (Latest):
Preempt_rcu
Xz compression (to reduce bw on the servers. other than that, don’t believe anybody telling you that it is faster)
New touch recovery (the one in my ICS repack) with gestures
GPU staycount implemented (this is the main reason of this release. this was droidphile’s request and I could not say no to him )
Disabled autogroup (samsung ICS kernel doesn’t use it neither)
ARM_ERRATA_754322 (once again, ICS has it)
Reverted workqueue implementation to old one
Some cleanup of redundant and non-necessary code
Reverted BFQ changes which were causing lags and lockups (thanks to Entropy512. I used the version in his repository. it was the easiest way )
Added “reboot into download mode” in advanced menu of CWM recovery and also added power-off back in. I had no time to remove dual-booting options. instead, I put “not implemented” message. they are ready but I am having a tiny problem while prompting user to choose the rom. you’ll have it in ICS, I hope.
Some fixes and corrections in extweaks interface (thanks to Entropy512 for some of them)
Initialization of led buttons to off (thanks to myfluxi)
Enabled cpu alignment (thanks to codeaurora)
Some other tweaks and “small changes”
2.6.13:
Fixed decoding issues because of the new cpuidle driver (thanks to Entropy512)
Set default I/O scheduler to deadline
Reverted lots of code back to v2.6.9 (based on the user experience, it is the best version until now)
Completed universal config interface implementation (the app will be posted when it is finished. the implementation at the kernel side is ready)
You may need to flash this in CWM recovery if you mess with the default config (especially when trying too much undervolting. although most of the settings are safe, changing gpu voltage and freq settings may cause lockups or bootloops): siyah-resetdefaultprofile.zip. this script will reset default profile and your device will boot with default settings.
This will be the last GB kernel release of SiyahKernel.
2.6.12:
Fixed BTHID issues (thanks to Entropy512)
Some wifi driver changes to prevent wlan_rx wakelocks preventing the device to sleep
New cpuidle driver from galaxytab (thanks to Entropy512)
Reverted top-off current back to default
2.6.11:
Replaced the recovery with Hyperdroid Redpill Kernel Recovery. (Thanks to Hyperdroid team and Redpill kernel developer(s)). this recovery can also mount both internal and external sd. (thank you [email protected])
Set the default cpu governor back to ondemand. conservative governor settings are still the same. ondemand governor settings are tweaked a bit (50000-90-5)
Changed some mali internals (set staycounts for steps to: 0-1-1 and down threshold for second step is set to 35). I did not use AndreiLux’s settings for not breaking the compatibility with voltage control app but I highly recommend you try it because it can save a lot of battery juice.
Some patches from upstream
2.6.10:
Default governor is set to conservative with sampling rate of 20msec. those who still say that lionheart is different than conservative governor should inspect the sources or those who don’t know how to do that should try this kernel to get a proof. if you still want EXACTLY the same lionheart governor, just flash lionheart.zip. Unlike what others say it will behave EXACTLY THE SAME as lionheart governor in void kernel if you flash it on this kernel, neak or several others who use netarchy’s change on conservative governor.
(Postponed to 2.6.11 to make a fair comparison of the conservative governor effects) drastic changes in gpu frequencies (thanks to [email protected]). you can use voltage control app to use modify them if they cause any lag in games or video playback but I didn’t feel any lag and they are just perfect. freq set is (40,167,267) with thresholds 85% 30% 80% 30%.
(Postponed to 2.6.11)Some other tweaks for performance and mostly battery life (made cpu hotplug threshods a bit high and some patches from upstream etc)
Set default i/o scheduler to bfq. it seems that song skipping doesn’t happen with bfq @ 100MHz (thanks to [email protected] for the feedback)
Applied Mel Gorman’s patches to SLUB allocator.
This release may not be as battery friendly as v2.6.9. I will make ondemand governor default and use different settings in v2.6.11 to target more battery life. apart from the slub allocator change (which should not effect the performance anyway) all changes in this release can be applied to v2.6.9 by using init scripts or voltage control app (just flash lionheart.zip and set i/o scheduler to bfq).
External SD/Internal SD are mounted backwards, careful when deleting information from them (emmc/sdcard) - Backup first!
Works with Samsung / CM7 / MIUI
Gokhanmoral - "Although I compile at&t version, Entropy512's kernel may be a better choice because there are some differences which I cannot test. He knows what he is talking about and I mean it..."
Flashing .ZIP's in CWM will change once flashing this KERNEL. You will now use the POWER BUTTON to select, and CHOOSE ZIP FROM INTERNAL SDCARD. Same goes for doing Backup/Restore, choose the Internal Card.
USB Debugging is turned off first flash, Just turn it back on Settings->Applications->Development
Great Explanation of Governors & I/O Schedulers
Using lulzactivev2? More control of the Governor from his Application
Overclock & Undervolt

Battery Life
BetterBatteryStats - Thread (Bottom 2nd Post) - With BetterBatteryStats you can analyse the behavior of your phone, find applications causing the phone to drain battery while it is supposed to be asleep and measure the effect of corrective actions
CPU Spy - Market - This is a simple app to display the time the CPU spends in each frequency state. This can be a useful tool in diagnosing battery problems or tweaking your over-clock settings.
It also displays the current kernel information.

Can be flashed on Samsung ROMs and AOSP Based ROMS. Currently all Samsung 2.3.4, 2.3.5, 2.3.6, 2.3.7 based ROMS, CM7 and MIUI ROMS are supported. Based on linux kernel 2.6.35.14 + drivers from Samsung sources
Auto-Rooting
ClockworkMod Recovery v5.0.2.7 with back button support
Touch Recovery
Boot animation support
Supports SetCPU (OC upto 1600MHz, UC downto 100MHz)
User customizable frequency steps. You cannot change the step count but you can change the frequencies at each step.
Supports undervolting (UV between 800 mV and 1500 mV)
Supports voltage control via SetCPU (thanks to netarchy, ninpo, hacre)
Stock voltages as default
smartassV2, lulzactive, lagfree governors. and lots of other governors which are available as modules
Default governor is ondemand (200-1200MHz)
Default I/O scheduler is deadline
Tweaked ondemand and conservative governors
Compiler optimizations

Although some parts can be considered as original, all are based on inspirations, examples and other people's code. I have no claim to be original. I am only trying to make my (and probably other's) SGS2 experience better and fun.
About source codes: I do not release source codes during beta testing. I do not use git. I have already proven that I share source code, but only once per release. I don't think that mods will be uncomfortable with this but if they are I can create an account in github and share an old code just like most of the other developers do. I will not choose that path if I don't have to. You can download sources for the releases using the links below. I will simply ignore mails and posts asking about the source code because they are already shared. Also, GPL doesn't force me to use github nor it forces me to release the source code as soon as possible. Therefore, releasing the source code may be delayed for several days. If you don't like this sue me

Question? If were running a hellraised rom will this kernel work our do we need an att rom?
Edit: just looked at his thread in the i9100 section. the kernel said compatible with aosp roms as well as in cm7 and miui. Is this true for this one?
Sent from my GT-I9100 using XDA App
Any issues with it? Wifi, reboots, battery life, ect, ect?
Edit: flashed it and everything went smoothly. No issues to report on. According to his thread it's just as stable as stock. Hope it stays that way for us.

Here's a quick link to the Siyah kernel over in the i9100 forums. Everything as far as information about the kernel should apply to our phones except the obvious (battery charging steps, anything with the home button, in other words strictly hardware difference related points) as he now has made an i777 kernel version.
http://forum.xda-developers.com/showthread.php?t=1263838
This kernel should get posted in the development thread by someone willing to keep up on all it's changes as the Siyah kernel seems to get updated all the time. Unfortunately once I heal up from surgery I won't have the time to be able to do that.

The CWM .zip will not download via phone browser, and when downloading from a windows 7 (IE browser) PC it successfully downloads but when flashing it says the package is bad. I think he needs to reupload it or put an MD5 checksum in place.
For stability, I ran a setcpu stress test on my phone all morning at 1.6 (nearly blew up my battery) and had no issues at all on conservative governor.

Included in Kernel-
-24 governors (ondemand default)
-6 io-schedulers (sio default)
-O/C up to 2ghz although not recommended
-fudgeswap
-slqb memory allocator
- Increased zram disk size
- Increased zram to 30%
- Changed LZO --- Benchmarks show compression and decompression times performance increased by double
- Linaro optimizations from my ics-beta
Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency
Virtuous (recommended) change with nothrills cpu or similar app
Virtuous is a modded smartassV2 which gives even more battery time then smartassV2
Intellidemand - Thanks to faux123
This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.
Lazy - Thanks to Ezekeel
The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand.
Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state
on a step overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.
-Ondemandx
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
BadAss Governor ?:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
Overclocked to 2ghz--- don't think its to stable though---
Please give feedback wether its stable for you or not if you overclock
FudgeSwap
-Helps improve multi-tasking in low memory situations forcing apps to swap.(already in DooM's sources)
SLQB - (SLAB allocator with Queue)-
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate).

VM tweaks (explained below)
VM Tweaks
dirty ratio and dirty background ratio 1 & 2
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.
dirty_expire_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.
dirty_writeback_centisecs
This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.
min free kbytes
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.
overcommit_memory
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.
Swappiness
A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.
VFS Cache Pressure
File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.

What is CIFS???
Server Message Block (SMB) or Common Internet File System (CIFS) are normally used to provide shared access to files on a network, mostly involving computers running MS Windows.
It allows you to conveniently mount/unmount your network accessible file resources and access the files transparently via your favourite Android app (playing music / videos, accessing documents etc.) Settings are stored on your SD card with permissions to write also to your SD card.
Now download CifsManager or similar app and configure it
Zram is not enabled by default- to enable it flash the wedgess-NEW-Zram-Enabler.zip below
If for whatever reason you want to disable it after you have flashed the .zip, just go to ect/init.d and delete 00zram
Cool, glad to see you got it working even if its not liking some of the governors.

So what do you think is the best combination of governor/scheduler for gaming?
Update your ROM and tell us how it goes.
Good news,
thanks for your work man, tonight i'm gonna put some Wolf in my phone.
I hope it is as performant as your ics work.

No lag here. Will post if there's any problems.
Wedgess thanks for making a gb kernel but can you add CDMA support for those of us on R800x on your spare time? If you dont mind I will fill you in about my xperia play.
This is a thread from doomlord that has a working CDMA kernel which is based on version 2.3.3 gb. Doomlord was able to create a 2.3.4 kernel for us R800x users but camera functionality doesn't work at all. (I was hoping for the thread to be revived but it seems development has been put to a stop) So were stuck on doomlord gb 2.3.3. Currently I'm using kernel v1 from doomlord that has a working recovery and i am not using v2 posted in the thread below.

Mybe i'm doing something wrong. Nova 3 seems to act pretty weird to. I really wonder... Mybe i should giv it a day or 2 just to get it use to with me phone hardware. Thanks again.:thumbup:
Edit; Do u think i should wipe cache n dalvik cache on the 1st boot after switching?? Mybe i should just do it just to be sure.

Strange alright i tried nova3 earlier and had no problems with it, it ran smooth for me, I say wipe it to see if it makes any difference for you, no hatm in trying.

Just did. Yupp it does makes a diff. Thanks man. Nova 3 respons a bit faster n the graphic seems a lot better too. Weird...
Mybe u should make a GB Linaro rom to match this kernel.

good stuff, glad to hear I know but my linux is running out of space due to the amount of kernel sources I have lol.ill have to push them all to github to make the 25gb+ space needed, which will take awhile Hoping some rom devs will release linaro built roms now, we’ll see though

I'll give this a try with DiXperia 2 rom this rom is fastest I've seen so far with doomkernel v14. I used lupus v4 with few ics roms and ran beautifully. Missed the great gaming in gb so this is very welcome as doomlord has moved onto htc one x thanks so much can't wait to try your kernel
I'm on dixperia 2 as well , will test it too. bye the way is this kernel support CIFS mounting ?
EDIT : working great, using Virtuous governor with SIO and it's really fast, coupling with dixperia2 its hell fast
I'm using a lot of launched apps (holo launcher, holo locker, whatsapp, viber, maps, setcpu for profiles, button sevior,
callrecorder, incredicontrol, exdialer, ivona, facebook, tasker, jellyB live wallpaper) have 87 Mo free RAM and its still fast and snappier than ever thanks to ZRAM and dixperia2 tweeks
CIFS isn't enabled and still have insmod problems like in doomkernel , @wedgess could you enable it in next update plz !

LuPuS-CM9-Kernel HERE
LuPuS-STOCK-GB Kernel HERE
LuPuS-iCs-BeTa Kernel HERE
Just after downloading AOKP jellybean last night and wanted to use my kernel so thought I would
make another LuPuS and release it, obviously certain things are still meehhhhh like the CWM glitching
and the camera which are things in all Xplay JB kernels/ROMS. So I reduced it down a bit from FXP and
given an extra 18mb of Ram so its not 368mb Ram, don't wanna go any lower. Once camera is fixed i'll make a 720p
version as well. Everything else thats added is the same with my most recent CM9 update.
This kernel was just built so its up-to-date with all of FXP's sources

- Deadline

Added Governors --
- lagfree
- brazillianwax
- smoothass
- scary
- savagedzen
- smartass
- smartassv2
- interactivex
- minmax
- + the 5or6 that are there with FXP
Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency
Virtuous
Virtuous is a modded smartassV2 which gives even more battery time then smartassV2
Intellidemand - Thanks to faux123
This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.
Lazy - Thanks to Ezekeel
The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand.
Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state
on a step overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.
-Ondemandx:
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
BadAss Governor:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
Superbad -
A "superbad" super smooth rendition of a highly optimized "smartass" governor!
Darkside -
A "slightly more agressive smart" optimized governor!
What else-----
-SLQB - (SLAB allocator with Queue)-(both)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate).
- Added Cleancache
- Updated zRam
- Lzo compression/decompression speed doubled on average

Multiboot[/SIZE][/U][/B]
For help and support on Multiboot, please check fma965's thread - "Noob friendly guide to Multibooting Jellybean"
Requirements:
Unlocked Vendor partition (see "Download/Installation" below)
System size below 310MB
ICS Only - AOSP-based ROM (not stock-based)

Features:
Huge thanks @CosmicDan
ICS and JB Support
One kernel, two worlds... you can install any AOSP-based ICS ROM (e.g. CM9, AOKP, etc) in any Slot (as long as it's multiboot aware, see below) and it will work automatically.
Team Win Recovery Project
CWM-Recovery has been replaced with the powerful TWRP. Full touch interface, file browser, backup names with keyboard, batch ZIP install, and more.
Multiboot RAMDisk
Pressing Vol-Down will now show a GUI for selecting which slot you want to boot or enter recovery on. Slot 2 and 3 are stored in ext2 images on your SDCard, and the process is fully automated and well-detailed to guide you through it. Please note that you can only install a ZIP in Recovery for Slot 2 and 3 if it is marked "Multiboot-aware" (see Compatibility section below).
Repair Tools
The Tools > Repair menu allows you to check your sdcard and sd-ext for errors and repair them. Also fix permissions and scan/repair Slot 2 and 3. This solves a lot of common problems with data and app2sd issues.
609MB data partition space
Cache is reduced to 8MB and system reduced to 280MB, giving a total size of 639MB for data. The ROM must be smaller than 280MB for this to work obviously (see "tested" section below). The cache is only 8MB so the kernel automatically links /cache/dalvik-cache to /data/dalvik-cache (simulates MIUI behavior).
Wifi Module auto-install
If the wifi module on the system doesn't exist or is different to the one in the ramdisk, it will be installed/replaced automatically. As an additional fail-safe, the kernel has magic checking (module version) removed - so any module will install on this kernel (but that does not mean it will work!)
Click to expand...
Click to collapse
Compatibility
The kernel has been tested and working on the following ROM's -
Turbo UI Preview (CosmicDan's source build) (Multiboot-aware)
Project Jellyzeus AOSP (CosmicDan's source build) (Multiboot-aware)
SlimBean for Xperia Play GSM/CDMA (cj360's source build) (Multiboot-aware)
P.A.C Man-PA (wedgess' source build) (Multiboot-aware)
Paranoid Android (wedgess' source build) (Multiboot-aware)
CM10 (Not multiboot-aware)
CM9 (Not multiboot-aware)
Please report if it works or not for other Jellybean/ICS-AOSP ROM's.
Click to expand...
Click to collapse
Bugs/Important Caveats
If your ROM has a "Reboot to Recovery" option, using it will load a broken Recovery where no mounts work. I can't fix this, so simply don't use it (just use Vol-Down on normal reboot).
Using Fastboot may trigger a "boot menu loop" - simply enter CWM-Recovery for any slot and then select reboot to solve it.
Click to expand...
Click to collapse
Important info regarding safe Multiboot
Do NOT install a ROM ZIP in Slot 2 or 3 until it is marked "multiboot-aware". Otherwise the ROM will format/install to your internal, no matter *what* you do. For details on how to make a ROM multiboot-aware, see this post.
To get around a ROM not being multiboot aware (if you want to install it in Slot 2 or 3), simply install in Internal (Slot 1) as normal, then set up the second or third slot with "Copy from Internal" instead of "Blank". Then of course you can reformat and reinstall on Internal.
Make sure your SDCard is free of errors. If you encounter *any* issues with a ROM, do a full Repair in the Tools menu before reporting any issues.
*Never* unmount SDCard in Recovery for Slot 2 and 3. But Mounting USB Storage is 100% fine.

First-time users - Enter Multiboot Menu (Vol-Down key) and go to Internal > Recovery, then format system, data and cache before doing anything else. Very important.
If you cannot enter the Boot Menu or Recovery after flashing, you need to flash the FTF first.
If you are running LuPuS-jB-v6 or older, the partition map has changed (30MB moved from data to system). You MUST Nandroid Backup before flashing the v7 update, then Nandroid restore after flashing. Otherwise you WILL lose your data.

VM tweaks (explained below)
VM Tweaks
dirty ratio and dirty background ratio 1 & 2
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.
dirty_expire_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.
dirty_writeback_centisecs
This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.
min free kbytes
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.
overcommit_memory
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.
Swappiness
A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.
VFS Cache Pressure
File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.

Considering ur on the PLAY development thread no. Go to the ARC thread
Sent from my GT-I9300
Why should I use this as opposed to the default kernel that comes with FXP?

VERSION 6
GB kernel for ALL MDPI can be found on this thread http://forum.xda-developers.com/showthread.php?t=2295108
Will update the OP later.
This kernel is based on the LuPuS Kernel for Arc/S by wedgess. All the changes in the kernel are done by him. A big thanks to wedgess. I have made this with his permissions and support. The Ramdisk is modified by me using the Stock from the ftf files.

Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency
Virtuous
Virtuous is a modded smartassV2 which gives even more battery time then smartassV2
Intellidemand - Thanks to faux123
This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.
Lazy - Thanks to Ezekeel
The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand.
Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state
on a step overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.
-Ondemandx:
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
BadAss Governor:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
Superbad -
A "superbad" super smooth rendition of a highly optimized "smartass" governor!
Darkside -
A "slightly more agressive smart" optimized governor!
What else-----
-SLQB - (SLAB allocator with Queue)-(both)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate).
- Added Cleancache
- Supports ext 2,3
- Updated zRam
- Lzo compression/decompression speed has doubled on average.
- Init.d support
- Fudgeswap
- And much more

All thanks to you for making such a great kernel. I will port your CM10 kernel next. I will start that few days later.
Couldn't thank you today. Limited to 8 thanks per day.
OMG !!!! just a couple of days ago i was recommending this for a friends of mine with an arc s wishing i could have a linario kernel like him for ics , cuz i have M66B's for cm10 and it's perfect !
now i have not only a linario but the same kernel, might be reverting back to ics afterall !
thanks sooooooooooooooooooo much !
Great work bud, keep up:good:
need to test this

VM tweaks (explained below)
VM Tweaks
dirty ratio and dirty background ratio 1 & 2
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.
dirty_expire_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.
dirty_writeback_centisecs
This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.
min free kbytes
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.
overcommit_memory
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.
Swappiness
A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.
VFS Cache Pressure
File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.
Show your support for the kernel and my work by putting this in your signature, its only a quick one I done up with my limited time

Perfect. Exactly what I needed. Will test it tonight

Nice work I take it this has fully working camera and USB Storage for stock based ROM's? A good choice for those who don't want JB.
Still cant boot my rom, doesnt even show the bootanimation :s

Ye well for the next few hours just ICS :silly: Ye fully working non multiboot of course, plus the script needs a big fix up, possibly make an app for it.

Wedges thamks for hard work on another kernel. Assuming you use Ubuntu to compile/build kernel, which version do you use? Im having problems on 12.04 with even setting up the environment.

I think he uses 12.04 or maybe still on 11.x when he told me. But I'm on 12.10 and had no problems setting up environment a while ago, using this guide.
P.S. You need 64-bit. Don't try on 32-bit, I did and spent days - can't be done
Oh man, I tried both 480 and 720 versions and my rom doesn't even show the loading animation.
It's an Xperia ICS based rom.

What ROM is it?? Having some strange problems with it not booting on Gin2Jellybean, but so far its the only ROM I can't get it to work with that i've tested
I'll download and test a few others to see how it goes
Hold on. I'm using the fastboot command line tool and seems I have something wrong because when I went back to Lupus v12 the phone didn't boot either. I'll try to flash it with Flashtool.
My actual rom is one of the Markphyton releases: ICS 4.1.B.0.431 (Patch 3)

Ok perhaps because u need to flash the unlocked vendor ftf which dan has a link to, ill update OP on awhile, so format partitions. Ive just also tested on my own ICS ROM I done awhile ago and its fine also. Need to figure out wht it wont boot on Gin2Jellybean now
Sent from my GT-I9300 On Official JB
SO, about ICS stock roms, this kernel needs having first flashed phoenix vendor ftf, like TurboKernel?
Ok, I'll wait for the updated info but with Flashtool I can't return to a previous kernel neither. Both Lupus v12 and this new kernel don't boot the rom, can't let me enter to recovery mode and reboot the phone a couple of seconds after the vibration.

well..i just flashed the kernel 720p version,volume down to enter recovery,did a full wipe and install krisdee ICS hybrid rom..get to bootanimation and reboot,reboot and nothing..
Back button doesn't do anything and pressing volume down shows me Aroma Filemanager.
Can be a way to flash another kernel and get the phone working again? Seems this flash has broken something.
so after flashing the 4.1.B.0.631.ftf firmware from Neo L and then this kernel I can say it works pretty well
