I have been using this for a while and have not faced any problems (I am using the last January build of BAM and Trickster from the market to modify) - I am now sharing with you today, a custom kernel for our device. I have permission by the developer to share this now, it was not intended to be shared at first as the developer has changed handsets and has removed links and source from the Russian Forum it originated. This was last updated in December 2013, so it might not be perfect with current CM sources as I know there were a lot of changes in the kernel and ramdisk! - This kernel might not be perfect, might not work at all for you but it sounds like the best kernel we have access to right now.
I have permission to use the source by my good friend mcaserg and share it with you all. Anybody who knows what they are doing, please update this in line with the latest changes from CM, and feel free to keep using it for every further release but give appropriate credits to mcaserg and if you really want to, me for finding it

To my understanding, (replaces hotplug control) and smooths out the way the cores work together and controls them more efficient. On paper it is supposed to be battery friendly without reducing performance by a great deal.

Oh? I like the sound of that. I'll test them both heavily for a couple of days and report my findings.
--edit--
So far it seems that CPU quiet will definitely eat up more battery life than Intelliplug. It likes to kick on all 4 cores with at least 3 of them kicking at 1.7GHz with the slightest touch. This is with mpdecision on and off. Dropped 4% in the last half hour with full screen on and and just playing with the settings through trickstermod. Bad for tge 9300mAh ZL battery in which i could do the same with maybe 1% drop. Just a heads up! Switching back to the intelliplug one for awhile.

Use the terminal emulator in ROM toolbox and run: dmesg | grep PVS
This will reply with a number from 0-4. 0 being slowest binned and 4 being fastest. The lower the number, the higher the voltage you need for higher frequencies to run with stability. I learned this through my old LGOG. Not all processors are made the same so this WILL vary between different devices of the same model. If the value is between 0-2, you will need to up the voltages of frequencies higher than the stock 1.7GHz otherwise you WILL end up with boot loops and crashes. 3 and 4, probably not. With fast (3), the stock voltages for frequencies that are included with this kernel will most likely work without issue. I have a fast binned CPU and have no issues. I have a fast binned CPU and haven't had any problems. Faster (4) should actually be able to UV the frequencies above 1.7GHz without these issues. In stock ROMs with the stock kernel, this is already taken into account and will UV automatically according to your CPUs binning. This will also determine how well your device handles lower frequencies. Mine, being a 3, handles 162MHz just fine. But I end up getting SoD (Sleep of Death) meaning the screen won't turn on after turning it off for some time, at 81MHz. From my knowledge, 81MHz minimum will work on 4s which the developer of this kernel probably has. Why put in something you've had time to test and it just NOT work?

Trickstermod is my app of choice for kernel customizations.
EXFat support has to be built directly into the ROM or can be installed by a mod. As far as I know, none exist for our device. There are a number of free programs for windows that allow you to format a 64gb sdcard to fat32 which will work on ANY ROM and ANY device running Android. I've had my 64gb class 10 SanDisk card formatted to Fat32 since my Atrix HD days and it still works on my OGP.
I posted a thread here in the general section about OC/voltages. Just waiting on someone to post the voltages on the stock kernel before I further my research into creating a list of voltages that will support up to 2.3GHz on our device.

I don't think it will mate. However, if you read through the original forum it was posted on (found in OP at the bottom of the page) you might find someone made a modded version, as someone did get it going with MIUI and some others.
For all of you OC fans or anybody that wants the most out of the kernel, read through the original forum (found in OP at the bottom of the page) as well and you can see other people that have played with the settings and have given screenies for it. There is so many helpful tips and setups through those pages, plus it has other cool stuff so have a read
Man this is really exciting!

THIS COMES WITH ABSOLUTELY NO WARRANTY.
I AM NOT RESPONSIBLE FOR WHAT THIS KERNEL MAY OR MAY NOT DO TO YOUR PHONE, ESPECIALLY WHEN YOU OC!
This is based on CM's 2.6.35.13 kernel.
Credits include Cyanogen, x99percent, scaryghoul, faux123, -snq, LordClockaN, and others that I couldn't find out who to credit for. If I used your code and you're not mentioned here, let me know!

- Added SLQB
- Added OC up to 1.9Ghz - SetCPU failsafe profiles are a MUST!
- Allocated more GPU memory
- Enabled swap
- Compcache is still disabled until I can get it working properly
Version 1.01
- Fixed 1.9Ghz OC
Version 1.02
- Fixed modules inside zip
Version 1.03
- Minor bugfixes
- Added TINY_PREEMPT_RCU (should help with multitasking)
Version 1.04
- Fix smartass (wouldn't go below 768mhz while awake)
- Minor bugfixes
- BFS
Version 1.05
- Added USB Mass Storage speed tweak
- Tweaked ext4 extensively
- LOTS of bugfixes
Version 1.06
- Added new governor "GreaseLightning" based on smartass

- Added Simple I/O Scheduler and set as default
- various PM fixes
- Merged HTC's vision-2.6.35-gb-MR release
- Tweaked charging code to "overcharge" for ~2 hours, should be safe and improve battery life
- Fixed netflix playback issues
GOVERNOR EXPLANATIONS:
'minmax' - this driver tries to minimize the frequency jumps by limiting
the the selected frequencies to either the min or the max frequency of
the policy. The frequency is selected according to the load.
Originally posted by erasmux -
smartass - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 - why?! - it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!
Originally posted by scaryghoul -
Scary - A new governor I wrote based on conservative with some smartass features, it scales accordingly to conservatives laws. So it will start from the bottom, take a load sample, if it's above the upthreshold, ramp up only one speed at a time, and ramp down one at a time. It will automatically cap the off screen speeds to 245Mhz, and if your min freq is higher than 245mhz, it will reset the min to 120mhz while screen is off and restore it upon screen awakening, and still scale accordingly to conservatives laws. So it spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It will give the same performance as conservative right now, it will get tweaked over time.

I hope to add some more user-friendly control to UV/OV, hopefully in the next version.
I tested this on my device, but as stated below, there's no guarantee it will work on yours.
This kernel should only really be used on CM7 nightly 78 and above. Not sure what'll happen if you use it on earlier nightlies, but it's definitely not supported.
Performance should be as good as or better than stock kernel.

not to get off-topic, but your sig says youre using the pyro kernel with the CM nightlies. You do know that blah said the recent nightlies are no longer compatible with that kernel, due to the CM kernel being rebased on a different kernel than the base of the pyro kernel. However, I can attest that this kernel DOES work with both nightlies and pyromod
Thanks for the 1.9GHz Will test in conjunction with the latest CM7 nightly when I get home!

I know the og post said that this should mainly be used with CM7 nightlies, but I decided to give it a try with the MIUI ROM that I'm using. No dice. Wouldn't even load the bootscreen. I'm thinking I may flash over to the current CM7 nightly to give it a try though.

I think it's just under a meg, for a total of 4 megs of GPU ram instead of 3 megs.
I don't know what kind of performance gain comes from it.. I'll have to benchmark it and let you guys know.
The added memory doesn't look like it was being used by anything else, though.

INFOBFS (Brain **** Scheduler):
BFS: The objective of BFS, compared to other schedulers, was to provide a scheduler with a simpler algorithm, that did not require adjustment of heuristics or tuning parameters to tailor performance to a specific type of computation workload. The BFS author asserted that these tunable parameters were difficult for the average user to understand, especially in terms of interactions of multiple parameters with each other, and claimed that the use of such tuning parameters could often result in improved performance in a specific targeted type of computation, at the cost of worse performance in the general case.[4] BFS has been reported to improve responsiveness on light-NUMA (non-uniform memory access) Linux mobile devices and desktop computers with fewer than 16 cores.
Information Source: http://en.wikipedia.org/wiki/Brain_Fuck_Scheduler & http://ck.kolivas.org/patches/bfs/bfs-faq.txt
Swap:
Swap: Swap is a way to extend your physical memory. The OS moves the less accessed memory pages to slower, and cheaper storage medium. This frees up RAM for things that require the speed.

Governor: this governor is rather similar to the 'ondemand' governor both in its source code and its purpose, the difference is its optimisation for better suitability in a battery powered environment. The frequency is gracefully increased and decreased rather than jumping to 100% when speed is required. Based off a lag free concept, with screen off profiles built in. demonspeed has not been tested against battery life performance, but rather for speed and user interaction.
[*]SuperBad Governor: A "superbad" super smooth rendition of a highly optimized "smartass" governor! Low latency and more responive to the user.
[*]SCARY Governor (@Scaryghoul): Scary - A new governor Scaryghoul wrote based on conservative with some smartass features, it scales accordingly to conservatives laws. So it will start from the bottom, take a load sample, if it's above the upthreshold, ramp up only one speed at a time, and ramp down one at a time. It will automatically cap the off screen speeds to 245Mhz, and if your min freq is higher than 245mhz, it will reset the min to 120mhz while screen is off and restore it upon screen awakening, and still scale accordingly to conservatives laws. So it spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It will give the same performance as conservative right now, it will get tweaked over time.
I/O Schedulers:
V(R) I/O Scheduler: V(R) is similar to, and based on, Linux's deadline I/O scheduler. It implements request deadlines which try to limit starvation, but provide no hard guarantee of request latency. It also merges and batches requests in a similar manner, but unlike deadline, read and write requests are issued together. This means there is no preference to reads over writes. Thus, higher throughput can be achieved at the cost of interactive performance. Secondly, V(R) could be used for situations where maximal throughput it the primary concern, such as batch processing systems, where per-request latency is not important. By scheduling read and write requests together and setting sufficiently high deadlines, V(R) can theoretically produce a better schedule than deadline, AS or CFQ.
RCU SubSystem:
RCU Concept: The basic idea behind RCU (read-copy update) is to split destructive operations into two parts, one that prevents anyone from seeing the data item being destroyed, and one that actually carries out the destruction. A "grace period" must elapse between the two parts, and this grace period must be long enough that any readers accessing the item being deleted have since dropped their references. For example, an RCU-protected deletion from a linked list would first remove the item from the list, wait for a grace period to elapse, then free the element. See the listRCU.txt file for more information on using RCU with linked lists.

Tiny Preempt RCU: This implements a small-memory-footprint uniprocessor-only implementation of preemptible RCU. This implementation uses but a single blocked-tasks list rather than the combinatorial number used per leaf rcu_node by TREE_PREEMPT_RCU, which reduces memory consumption and greatly simplifies processing. This version also takes advantage of uniprocessor execution to accelerate grace periods in the case where there are no readers. The general design is otherwise broadly similar to that of TREE_PREEMPT_RCU.

Yeah speeds are good but nothing compared to cm7 or miui.. I was testing the kernel on VU for a few hours and I forgot how much different sense really is.. The high quad score I got was 3500, I hope that is on par for a sense rom.. The responsiveness is there, just hope battery life is good?? I basically ported all the stuff from my. Other kernel, so should be good.. Going to need feedback on this one cause I don't really use sense, not my cup of tea... So let me know all you sense users and abusers

- Misc compiler tweaks
[B][U]v0.08[/U][/B]
- Up patched to 2.6.35.13 source
- merged some changed with Da_G's skyrocket source to fix cpu1 hot-plugging
this shiould solve issues of users having min clock stuck at 384mhz and/or max
stuck.
- fixed vdd_tables, system tuner will be supporting my kernel in up coming releases for this
system tuner, should no longer cause issues. as the hotplug fix solved this
[B][U]v0.06[/U][/B]
- Found tome Carrier IQ **** in tty consoles, removed it
sneaky sneaky...
- patched for call recording <--- DERP apparently it works with out my patch LOL
[B][U]v0.05.6[/U][/B]
- redid source tree from scratch
- Switched on OTG config options again (had them shut off)
- Battery issues resolved
- minor tweaks to autogrouping
- set kernel HZ to 300 for a smoother more responsive feel
- minor tweaks to lag free and smartass
- undervolts have been tested stable by many users and are in this release
[B]- PLEASE UNINSTALL SYSTEM TUNER AND CLEAR DALVIK CACHE THIS RELEASE[/B]
[B][U]v0.05.2[/U][/B]
- loosened up lag free so its not so twitchy at low freqs and ramping up and down constantly
- undervolted all freqs a fair bit
- added smartassv2 back in *Please TEST, i think i have solved the hang at max freq on wake*
- probably forgetting something else i messed with
[B][U]v0.05[/U][/B]
- sourced a multiprossesor service that actually wasnt ****ed and added to kernel
- turned on multi prossesor service and set it to shut off the second core on screen off
or when not needed, and only turn back on when needed
- Patched in BLN *thanks to romanbb*
- Patched services.jar to allow bln to notify you for most notifications from apps now
eg: gtalk, mms, sms app and ect..
- spiffy new boot logo ;)
[B][U]v0.04.1[/U][/B]
- removed smartassv2, its useless in its semi-working state, causing battery drain. I will figure out what its up to.
[B][U]v0.04[/U][/B]
- Lowered stock voltages a bit to get some better battery
- Fixed (i think) smartassv2 ramping up to max clock and then neglecting to ramp back down on wake from sleep
- Recommend using lagfree :)
[B][U]v0.03.2[/U][/B]
- fixed scheduler settings for new min freq, causing me SOD's on screen wake with notification
[B][U]v0.03.1[/U][/B]
- disabled 192MHz in the clock table so users cannot select it and cause a sleep of death situation.
- Default min freq now 384MHz
[B][U]v0.03[/U][/B]
- added in BFQ scheduler if users choose to use it you can use system tuner or other favored apps to change from CFS
- Added SmartassV2 and Iterative schedulers
- Tweaked SmartassV2 for our device
- Added ability to change voltage on the cpus with vdd_tables
[B][U]
v0.02:[/U][/B]

- Autogrouping of scheduler added
- lagfree cpu scheduler added, with fully working sysfs interface to edit settings not set by default but recommended! its TITS!
- optimized build flags
- removed sysfs for vdd tables, we have not got it working yet. no worries you shouldn't need it yet ;)
- kernel compression changed for much faster boot times
[U][B]v0.01[/B][/U]
CK3+ Patch Set (Thanks to fellow Team Synergy member Ziggy471 for backporting)
OC 1.8 (Thanks to Romanbb's source tree)
Global UV Tables (Thanks to Romanbb's source tree)
All Debug shut off except samsung debugging (needed)
LZMA compressed
Carrier branded boot splash removed
init.d support
Voltage Control
You can control it via shell/init.d scripts as follows
To over volt ALL frequencies by 10000 uv:
Code:
echo "+10000" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_table/vdd_levels
To under volt ALL frequencies by 10000 uv:
Code:
echo "-10000" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_table/vdd_levels
To set a specific frequency (ie 1.8 GHz) with a specific voltage (ie 1.25 volts) ]
Code:
echo "1836000 1250000" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

Here is a kernel Houstonn and I have been working on. It's based on Faux123 kernel for nexus 4, however, it has evolved into a "buffet" kernel. I keep choosing what i believe is the better interface / way of doing things in a choice of various way or what could give us better battery / performance. I'm trying to maintain a certain balance.
This version is for geehrc (Sprint/Internationnal) with the 13mp. If you have the 8mp phone (E973/E971/E970), use that thread : http://forum.xda-developers.com/showthread.php?t=2229742
I won't link to Faux123 kernel in the nexus 4 for the simple reason that 99% of the people don't read and on these 99% of people, a few will end up flashing nexus 4 kernel which mostly flash by partition number and not by partition name thus hard bricking their device.
Reason to at least try it :
CPU voltage table
Intellidemand and Wheatley governor added
All the block I/O scheduler
TCP Westwood algorithm
Faux123 sounds interface
Faux123 gamma interface (color control)
Newest Prima (wifi) driver.
In-kernel thermal watching
Msm_mpdecision (In-kernel OpenSource MPDecision)
Frandom module loaded at boot.

FransicoFranco Drivers
Thanks for making this kernel, it is much appreciated. I'm wondering where to get/enable the generic hotplug driver and the sound driver by FransicoFranco. Thanks.
I have a sprint lgog and I tried running the eos 4.2.2 ROM for a few days. The battery life was pretty bad compared to the lifeless ROM so I restored back to that. Anyways, will this kernel improve the battery life?

I've managed to get pretty comparable (not 100% sure) battery life on AOSP compared to Stock Roms. Not to speak for the developer but yes this will increase your battery life. The only thing is that there is a lot you can tweak which will have an effect on your battery life. This is what i do.
Turn mpdecision off. MPdecision is a hotplug driver made by qualcomm that can be disabled in AOSP. As of now its always active on stock roms. I'm still trying to figure out where to get the Francisco Franco hotplug drivers, which are prefered.
Underclock your cpu/gpu - I like to keep my max at 1026mhz and my gpu at 200mhz. I don't notice any significant lag.
Undervolt your cpu
Use a intellidemand/tune your on demand governor
Obviously wake locks come into play as well. I like to use better battery stats to see whats keep my stuff awake.
Finally keep your mobile data off when your not using it
Sorry if I'm just telling you stuff you know, just trying to be informative.

No more mpdecision. Msm_mpdecision in this kernel is different. It's opensource, in-kernel and doesnt force you to 1026mhz minimum freq,

sweet. I was using fauxclock to control my cpu. I am a little confused on msm_mpdecision
is msm_mpdecision the generic hotplug driver by FranciscoFranco?
Is there a more appropriate app than fauxclock to use?
If I disable mpdecision in fauxclock, does that automatically enable msm_mpdecision?

Nope, msm_mpdecision is not franciscofranco hotplug drivers. I had franco driver before and it lagged too much. Also, there is no mpdecision at all. I remove the executable on installation of houcha. Seems as fast as mpdecision without the locking the minimum freq to 1026Mhz.

cool, just for some feedback I feel that there definitely is a difference in my processor states when I enable/disable mpdecision in fauxclock.
When it's enabled, the first core sits at 384mhz until i touch the screen, then the first two cores jump to 1026mhz or 1516mhz.
When I disable it my first core sits at 384mhz and jumps up to 700-1100mhz when I touch my screen, the other cores stay quiet.
In both circumstances I'm using Intellidemand governor.
As long as I'm bugging you, My gpu frequencies are a bit wonky. It goes to 400mhz on boot. When I lower it to 128mhz it will sit at 128mhz and not jump up no matter what max frequency or governor I reset it to.

Try downloading the newest version. fs version have faux sounds, others have franco sounds. I believe faux app read gpu freq incorrectly. If you swipe tab (which is gpu demanding compared to stay to same tab) you will see the gpu freq actually lower.

I'm not sure what sounds to use, does anyone want to explain the differences? (I'm using faux right now but considering trying out franco since I use the franco updater app to control everything)
Cerux Kernel for TW JB 4.1.2 ROMs:
For Samsung Stock = TouchWiz 4.1.2 ROMs
Features:
Updated kernel to 3.0.66 (will continue updating it as build continues)
OC up 1836 Mhz
GPU OC: 2D 160-266, 3D 266-320 MHz
Kernel msm_thermal control
Force min/max frequency changes for both cores when changes are applied to one core, this is useful for those using built-in performance settings or using a cpu app that changes only core0 while keeping core1 intact. (enabled by default)
Modified ondemand governor with touch boost to have a snappier scrolling/typing, and with a second phase which will go first to configured frequency 1242 MHz before reaching max.
Kernel based mpdecision. This will control CPU secondary core (core 1) hot-plugging and unplugging depending on CPU load
Frandom support
Fixed a bug where phone hard reboot after trying to make a call before device is ready.
Added BadAss governor
Added SmartAssV2 governor
Added Wheatley governor
Added Intellidemand governor
Added V/R scheduler
Added SIO scheduler
Added BFQv6 release 1 (read second post)
Added BLN support (you need software/rom support)
Ondemand is the default governor
BFQ is the default scheduler
Other things I might forgot and will add later

Recommend using this ROM and if coming from a different kernel wipe.
ROM: http://forum.xda-developers.com/showthread.php?t=2249770
Go thanks: @Rushing
Please don't report problems without wiping.
If you get on splash screen after a reboot on any rom try this in recovery:
Code:
adb shell
e2fsck -yfDC0 /dev/block/mmcblk0p25
then reboot.
TricksterMod recommended for the tweaks
Few notes:
To other devs:
Lets play fair, if you are going to use any source of this kernel, make a pull request and/or PM me any findings you have.
To user: don't compare this kernel to other ones, I consider it rude. If you like other, you are free to use them.
No ETAs
No Sweep2Wake... I will look into it later

Enjoy the kernel.
Since version v1.02 BFQv6r1 has been added and set as default scheduler. Advantages of BFQ:
Low latency for interactive applications - Whatever the background load is, the disk is virtually as responsive as if it was idle. Normally applications experience high latencies or become unresponsive until the workload terminates (especially SSDs)
Low latency for soft real-time applications - soft real-time applications, such as audio and video players or audio and video-streaming applications. These applications do not suffer from almost any glitch due to the background workload.
See a demo here: http://youtu.be/J-e7LnJblm8

Use trickstermod to enable it...
Edit:S2W will come... and maybe screen sweep, not just the keypad

Probably you have fast charge enabled... It works excelent for me.
Check with:
cat /sys/kernel/fast_charge/force_fast_charge

0 means it is disabled. Are you testing in windows? I always use Linux, windows just in the office but I will try with it.
