This kernel is based on teamhacksung's kernel, with updated Linux base to 3.1.10
Kernel working for Teamhacksung build 13 to 17 (+ nightlies) and also ICSSGS RC3/4.
Features:
- Brain **** cpu-scheduler (BFS) (this should be much faster than the default cpu scheduler) will be back later
- 378, 391 and 403 Mb Ram available (selectable in kernel, no need for a patch (403 mb breaks 720p) only reboot required)
- 2 different recoveries included (cmw touch recovery + twrp recovery)
- SIO scheduler (default)
- V(R) scheduler (maybe even faster than SIO, can be set as default by using NSTools for example)
- init.d
- Voodoo Sound and CM9 Color Adjusment / Voodoo Color (VC version)
- Devil Idle
- BLN V9 (thx to mialwe)
- USB Host mode driver (for more information about this, and for saying thanks to the guy, who ported this for our phone, please visit this thread: http://forum.xda-developers.com/showthread.php?t=1450298 )
-Ezekeel's Live_Oc
- Ezekeel's Deep Idle V2
- Touchwake
- vibrator intensity control (by mialwe)
- BLX (Batterie Life Extender, I don't think we need it, but maybe one feels better by using it )
- backports from Linux 3.2
- Swap/Zram support
- Zcache, Cleancache and Frontswap
- Smooth_ui included to ondemand, conservative, smartass, lulzactive, lagfree and lazy governor (only one setting for activating/deactivating it in general)
- 3 cpu governor presets (smooth, normal, powersave) for ondemand, conservative, smartass, lulzactive, lagfree (only one setting for switching the mode in general)
- many other small features and improvements

changelog 24.05.2012:
- Smooth_ui included to ondemand, conservative, smartass, lulzactive, lagfree and lazy governor (only one setting for activating/deactivating it in general)
- 3 cpu governor presets (smooth, normal, powersave) for ondemand, conservative, smartass, lulzactive, lagfree (only one setting for switching the mode in general)
- no need for activating/deactivating of selective live_oc anymore --> just change target low and target high
- BLX back in
- fixes to devil idle to be more stable while in call
- 1,5 mb more ram (thanks to mialwe)
- added aroma filemanager to cwm recovery
- added fully working TWRP recovery optional to cwm recovery (to use TWRP, just create a file named "twrp" at /cache)
- added option to select ram config in kernel --> no need for flashing an other kernel to get more ram (thanks to stratosk)
you can change ram setting by doing (or use command center or similar):
echo 1 > /sys/kernel/bigmem/enable (this gives you xl mem of 391 mb)
echo 2 > /sys/kernel/bigmem/enable (this gives you bm mem of 403 mb (this is breaking 720p))
echo 0 > /sys/kernel/bigmem/enable (this gives you cm9 default mem of 378 mb)
you have to reboot to make changes work

- switched to new initramfs from stratosk and mialwe ( now there will be cmw zip and odin tar file of every kernel version)
- added possibility to use Zram instead of Swap
- no need for flashing/using special scripts to make swap/zram working anymore
echo 1 > /data/local/swap_use (for using swap partition on external sd card, you have to create this partition before)
echo 2 > /data/local/swap_use (for using Zram, no other modifications required)
you have to reboot to make changes active. You can't use swap and Zram at the same time

- added zcache
- added frontpage
- added cleancache
- added fudgeswap (thanks to ezterry and faux123)
we will add in fudgeswap as long as its less then the free swap
Setting this to a very large positive number will indicate swap ought
to be fully used as free (and will slow the system down)
smaller numbers will allow you to put some pressure on SWAP without
slowing the system down as much.
small negitive numbers will allow the system to be faster at the same
minfree level.
default is 512 to give a very little bit of pressure to use some swap
but this can be modified at runtime via:
/sys/module/lowmemorykiller/parameters/fudgeswap

changelog 01.05.2012:
- all changes from cm9 stock kernel (including mount points option)
- some fine tuning to deadline and sio
- Devil Idle: limiting bus/ram/gpu speed to 100 mhz for 100-800 mhz cpu freq, while screen off (automatic mode) or always (permanet), both modes automatically reduce the int voltages of the affected freq by 50 mV
activate automatic:
echo 1 > /sys/devices/virtual/misc/devil_idle/bus_limit_automatic
deactivate automatic
echo 0 > /sys/devices/virtual/misc/devil_idle/bus_limit_automatic
permanet on:
echo 1 > /sys/devices/virtual/misc/devil_idle/bus_limit_enable
permanet off
echo 0 > /sys/devices/virtual/misc/devil_idle/bus_limit_enable

- compiled with swap support
- added stratosk's smooth_ui to lulzactive governor (activated by default)
activate:
echo 1 > /sys/devices/system/cpu/cpufreq/lulzactive/smooth_ui
deactivate
echo 0 > /sys/devices/system/cpu/cpufreq/lulzactive/smooth_ui
with this feature enabled, cpu freq jumps up to max freq, by touching the screen.
Click to expand...
Click to collapse
- rest oc_value to 100 while screen off, and back when screen turns on (combined with devil idle automatic, can't be turn on/off without devil idle)
- added posibility for different voltages while screen off (also bundled with devil_idle, with default settings, stock arm voltages are applied, because of live_oc set to 100)
this is an example, how to apply screen_off arm voltages:
echo 1450 1400 1350 1275 1075 975 875 800 > /sys/class/misc/customvoltage/arm_volt_screenoff
this way, it is possible to undervolt while screen off, but overvolt and overclock while screen on
for now, the int voltages can not be changend
Click to expand...
Click to collapse
- added the possibility to set freq limits while screen off (min and max freq)
echo 100000 > /sys/devices/virtual/misc/devil_idle/user_min
echo 800000 > /sys/devices/virtual/misc/devil_idle/user_max
both are independent from devil_idle, and get applied when screen turns off
by default 100 and 1000 mhz are set.
values which can be puth here are all "stock" freq (without live_oc level) multiplied with 1000. live_oc values get applied automatically.

- even better fix to selective live_oc (last one (in test kernel) generated some overhead)
- fixed sampling rate of ondemand and conservative (have ported mialwe's/stratosk's sleep multipliers)
- new tunables for ondemand and conservativ
sleep multiplier and tunables:
mialwe and stratosk had the great idea, to change the sampling rate of conservative and ondemand governor while display of. for this, he introduced the sleepmultiplier (in his case factor 3). this means, if you set sampling rate to 20000, it changes to 60000 while screen off, and back, when screen on.
for ondemand and conservative:
i have made this multipliers tunable. proper values are between 1 and 5, because one could want a higher multiplier while screen off, if sampling rate is very low while screen on (higher sampling rate means, less checking for work load --> better batterie, worse performance). with this tunables you get better batterie, without making the performance worse while screen on.
two other tunables: up_threshold_min_freq and responsiveness_freq
the first one is a very low threshold while on low freq (by default 40), to make the governor scale up faster, until the responsiveness_freq is reached.
the responsiveness_freq is set to 400000 (400 mhz) by default. while the freq is below this value, up_threshold is the same as up_threshold_min_freq, and freq jumps to responsiveness_freq, with skipping the freq between the actual one and the responsiveness_freq. (conservative governor does not jump up to this step)
responsiveness_freq can be set to values between 100000 and 1400000
up_threshold_min_freq can be set to the same values as the normal up_threshold.
not tunable: while screen off, up_threshold is set to 95, no matter your other settings, to save more batterie.
till now, the tunables have to be changend by:
echo VALUE > /sys/devices/system/cpu/cpufreq/ondemand/VARIABLE_NAME
and
echo VALUE > /sys/devices/system/cpu/cpufreq/conservative/VARIABLE_NAME
example:
echo 400000 > /sys/devices/system/cpu/cpufreq/ondemand/responsiveness_freq
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold_min_freq
echo 5 > /sys/devices/system/cpu/cpufreq/ondemand/sleep_multiplier
up_threshold_min_freq is disbaled by default for conservative governor
(this can be done by setting the up_threshold_min_freq to 100.
for ondemand, this also disables the additional jump to the responsivenss freq)
Click to expand...
Click to collapse
for lulzactive:
for this governor, i did similar things, but they are not tunable till now.
when screen off:
- inc_cpu_load is set to 90, and back to the original value, when screen turns on
- up_sample_time is set to 50000, and back to the original value, when screen turns on
- down_sample_time is set to 40000, and back to the original value, when screen turns on
other changes:
- fix to touchwake from ezekeel, and another fix from stratosk
- upstream fix to compass
- building for i9000B now, too (big thanks to F4k for the hints by pn )
- removed some typos from recovery
- removed some annoying "no's" and "yes" from recovery in misc menu
- fixed wifi mode switch (pm_fast is the one with better signal)
14.04.2012:
- new b versions (only stock ram) changend to 377 mb, VC version needs the 720p fix from my ftp server. cmc version already patched
13.04.2012:
- updated wifi driver
- added the possibility to switch between wifi PM_Fast and PM_Max mode (Pm_Fast = better signal, PM_Max = better batterie, default is PM_Max)
echo 1 > sys/module/bcmdhd/parameters/uiFastWifi (pm_fast)
echo 0 > sys/module/bcmdhd/parameters/uiFastWifi (pm_max)

- user interface to disable fsync (this gives more performace, at the risk of data loss on a crash, taken from ezekeel, so it should be ok ), default is off, to be safe
echo 1 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled (fsync enabled)
echo 0 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled (fsync disabled)

to make this settings apply after reboot, select them from recovery --> devil --> misc
- fixed voodoo color kernels (these have the VC in their names)
10.04.2012:
- added vibrator intensity control (by mialwe), presets can be changend in recovery
- stock ram version now available (348 mb ram), XL (390 mb), XL_bm (402 mb)
- removed 1080 mhz freq for now
- small correction to touchwake
- small correction to selective live_oc (now the low freq really are not live_oc'ed)
to change the vibrator intensity on the fly, you have to do the following:
Code:
echo [B]value [/B]> /sys/class/timed_output/vibrator/duty (where value is between 20000 and 43640)
if you want the changes to be applied at boot, you have to use one of the presets from recovery, use an init.d script, or:
echo [B]value [/B]> /etc/devil/vibrator (where value is between 20000 and 43640)
05.04.2012:
- fixed bug in selective live_oc, which caused the target high not taking affect to the highest freq, if highest freq equals target high
- fixed another bug in selective live_oc, which could lead to gpu crashes due to overclocking the ram, but not the cpu freq (for low steps)
- added a switch to change between "normal" and selective live_oc
(can be changend in recovery, devil menu --> performace --> liveoc,
or by (this won't stay after reboot):
Code:
echo 1 > /sys/devices/virtual/misc/liveoc/selective_oc (selective mode)
echo 0 > /sys/devices/virtual/misc/liveoc/selective_oc (normal mode)
by changing the live_oc mode while using it, live_oc value is set back to 100, to prevent strange things
- added possibility to set max. freq for boot (in recovery). This freq is set until init.d is executeted (it is automatically set to 1000 at this point, to make sure there are no conflicts with other cpu settings from users)
#Already in the last version, but i forgot about it:
- deep idle fixes from stratosk (many thanks)
- added possibility to underclock by using live_oc (limit is 90 now, which means lowering all freq and bus speed by 10%, to save more batterie when really needed)
03.04.2012:
For now there are three different RAM versions:
- stock mem kernel has 379 mb ram, everything working
- "slim ics" (XL) kernel comes with 390 mb, this is breaking playback of some high resolution videos
- XL_BM is coming with 402 mb ram, but breaking 720p
(while flashing the kernel, the modded rom files are also flashed, so you don't need to flash a new rom to get 379 or 390 mb)
-added new frequency: 1080 mhz (1100 does not like live_oc)
- fixed SmartassV2 for live_oc (after changing live_oc value, you have to change the smartass values, too, but then they automatically apply to the live_oc value (although you can only select 800 mhz in nstools (for example))
- touch recovery with custom devil menu (for some reason it takes a few seconds to load the first time, missing virtual keys is a warning, because there are no virtual keys yet)
-fast charge (thx to chad0989 for this), disabled by default.
activate fast charge:
Code:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
deactivate fast charge
Code:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
you also can use the widget from chad (to place on homescreen) to toggle the fast_charge mode

Questions and Answers:
Q: What are BFS and CFS?
A: The Brain **** Scheduler (BFS) is a task scheduler designed for the Linux kernel in August of 2009 as an alternative to the Completely Fair Scheduler and the O(1) scheduler.[2] BFS was created by veteran kernel programmer Con Kolivas.[3]
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 16cores.
Q: Is BLN is not working for sms?
A: It is working, but you have to disable "turn screen on" in your sms app.
Q: What the hell are all these governors?
A: here you should find the answer: http://forum.xda-developers.com/showthread.php?p=19846297
Q: What's a good setup for live_oc??
A: No one knows. Every phone is different. It seems like the folling setup is running well for some (many?) users. If you get reboots with it, you have to find the setup for yourself.
if you are satisfied with this configuration, please hit the thanks button of Crack: http://forum.xda-developers.com/showpost.php?p=22194160&postcount=1246

Q: What is Touchwake? Can you explain it?
A: With Touchwake, the touchscreen still recognices your fingers, after turning off (for a predefined time (NSTools)). For a detailed explenation, take a look at Ezekeel's thread: http://forum.xda-developers.com/showthread.php?t=1239240
Q: How can I make Voodo Color settings been saved after reboot?
A: You have to use Voodoo Pro App, because of changes between Gingerbread and ICS, and only the Pro app is updated till now.
Q: Which is the best IO Scheduler?
A: I think SIO and V(R) are the fastest.
Q: How can I enable DeepIdle/Live_Oc?
A: You have to use NSTools. You find it on market. It's free.
Deep Idle Questions:
Q: What's the meaning of TOP=Off and TOP=On when I look at the Deep Idle status?
A: When TOP=Off is used, the best powersaving state is used. TOP=ON will be shown, when bluetooth or gps are running.
Q: In Idle status I only see TOP=On. What's wrong here? I don't use Bluetooth or Gps.
A: You have to flash the modded framework-res.apk, because ICS does not fully deactivate bluetooth by default. Even if you never use it.
Q: Idle Stats only are showing Idle, but no Deep Idle. Why?
A: An App is preventing the use of Deep Idle. At first, you should try closing the cam, running in the background. Also rebooting should solve this problem.
Q: Which CPU governor is the best for use with Deep Idle?
A: As Ezekeel stated, one should use LAZY
What about init.d support?
This looks great, exactly what I wanted. Testing now, will report back.
update: everything installed perfectly, running well. Still testing stability.
Thank I will test it right now

Everything standard, no tweak, deep sleep activated (and modded framework flashed).
Camera Zoom
Great kernel! , Deep idle working fine
However it looks like either the kernel or the framework patch broke camera zoom
How to see if Deep Idle is working? I flashed the zip and enabled, after 20minutes it still show only Idle in stats.

This kernel is based on teamhacksung's Linux kernel 3.08 for i9000 only.
Features:
- Brain **** cpu-scheduler (BFS) (this should be much faster than the default cpu scheduler)
- SIO scheduler (default)
- V(R) scheduler (maybe even faster than SIO, can be set as default by using NSTools for example)
- 337 mb Ram available (720p recording working)
- Voodoo Sound and Voodoo Color (Voodoo Color will be replaced by Pawit's color adjustment with coming build 14, because it will also contain gamma manipualtion)
- Neldar's BLN (for blinking, BLN Pro App needs to be used, known issue: After blinking for the specified time, leds turn off)
-Ezekeel's Live_Oc (I recommend not to go higher than 115% because of overclocked GPU)
- Ezekeel's Deep Idle V2 (you have to flash the attatched modded framework-res.apk, to make this fully working, because ICS is preventing Bluetooth to really shut down)
- many other small features and improvements
For enableling Deep Idle or using Live_OC, you have to use NSTools, which can be found at market for free.
Don't flash the modded framework-res.apk on Onecosmic's rom!
It is taken from perka, and only working for teamhacksung's build.
I try to support this kernel as good as possible, but due to family and university, I do not have much time, so please be kind, if it takes a little bit longer till I will answer your questions.

sorry,differences between the two files are only led and bln?and never undertsnad if deep idle is enabled on stock kernel of pawtip,beacuse my battery life it's ok..
Please read what you quoted. All answers are there.
Specifically:

That's a nice kernel. Deep sleep 100% wow!!...great job, mate.
Very, very good..
my wifi dosnt work, the on and off button just keeps flashing on and off constantly, tried flashing several times, even clean wipe and no luck, i also get a random offset every time i install teamhacksung ics, the offset is always different

Maybe you should wipe caches. I released the kernel 2 days ago in German forum, for stability testing, and no one reported this before
@silitek: this is a bug of CPU spy, due to liveoc. I have to fix this in the next version.

my wifi dosnt work, the on and off button just keeps flashing on and off constantly, tried flashing several times, even clean wipe and no luck, i also get a random offset every time i install teamhacksung ics, the offset is always different
Click to expand...
Click to collapse
The random offset is a new google security feature. Nothing to worry about. It SHOULD be different each time, 'cos it's random innit...

These kernels are provided as-is without warranty. I'm not responsible for any problem you can encounter with your phone or if your cat suddenly dies.
Although, don't expect support even if I will eventually help since I love cats.
Note : These kernels are only compatible with CyanogenMod and MIUI roms !

Overview :
- Up to 1.7GHz CPU OC with added bus/GPU OC (Thanks to morfic for the great base of work)
- Undervolting (using third party apps)
- Voodoo Sound & Voodoo Color (Thanks Supercurio & renaudallard)
- FPS uncap (Screen running 68Hz instead of 60Hz, from 56 to 66 FPS max) from JPX source
- Various tweaks for more smoothness and reliability
- LED notifications using Neldar's BLN
CHANGELOGS IN #2 POSTThe frequency/voltage & informative UV settings table is as follow for V13 kernel :
Note that these UV settings will be unstable on many devices. It's only informative.
1700 MHz - [email protected] 243 MHz - 1.500v / -> Most phones will fail here. -25 to -50mV may help to stabilize. Much stabler as unique frequency for benchmarks.
1600 MHz - [email protected] 229 MHz - 1.500V / -> That's high and many devices will fail on this frequency. Find working UV for you if any.
1500 MHz - [email protected] 250 MHz - 1.500V / -25mV
1440 MHz - [email protected] 240 MHz - 1.475V / -50mV
1400 MHz - [email protected] 233 MHz - 1.450V / -50mV
1300 MHz - [email protected] 217 MHz - 1.400V / -50mV
1200 MHz - [email protected] 200 MHz - 1.350V / -50mV
1000 MHz - [email protected] 200 MHz - 1.250V / -50mV - If you have stability issues, try to let this one by default.
800 MHz - [email protected] 200 MHz - 1.200V / -75mV
400 MHz - [email protected] 200 MHz - 1.050V / -100mV
200 MHz - [email protected] 200 MHz - 0.950V / -150mV
100 MHz - [email protected] 100 MHz - 0.950V / -200mV - (can be very different between two devices)
GPU frequency is linked to bus speed
More volts is not always equal to more stability. Try to add more UV (less volts) if the frequency you're trying to achieve is unstable.
Considering all phones will respond differently to OC/UV, to tweak the values to suit your device will be required.
By default, no overclock/undervolt is applied. You'll need to use one of the tools below to adjust the frequencies and voltages.

03/06/2011 - V10B To use with newest builds only (equal or newer than 28/05) !
- Upstream sync (FM radio, new Voodoo Sound implementation, etc...)
- Back to 4.4.3 toolchain - needed for new RIL
- Big cleanup - rewrite from scratch
- Many fixes
- New tweaks for speed on 4.4.3 toolchain
- New tweaks for stability on 4.4.3 toolchain
- Black magic
17/06/2011 - V10C (Updated) To use with newest builds, #28+ for i9000 or equivalent
- Upstream sync (cpuidle, updated drivers (wifi etc.), Recovery 4.0.0.x, etc...) (updated as of today 17/06)
- More debug stuff disabled
- Dock audio support (experimental)
- Added DIDLE (Deep Idle) support (removed, buggy)

- New step by step frequency switch when scaling down (part of the Galaxy S II port from Bilboa1) - more stability on highest frequencies
- Corrections and further tweaking on smartass governor + some fixes from Netarchy (Nexus S). 400MHz lock when screen is on removed (not needed anymore -> more power saving)
- Higher cache for faster SDcard read speed
- New sleep settings : Effective lock to 400MHz max when screen is off -> fix long wake up/hiccups when playing music or similar use. Be careful with your UV settings on 200 and 400MHz steps to avoid sleep of death problems ! These were not used on previous versions of my kernel (locked to 100 MHz when screen off and locked to 400MHz when screen on with a buggy gap in smartass governor forcing generally 600+ MHz)
- 600 MHz step removed (it was generating instabilities on some phones when jumping to 800 or down to 400 when using UV)

- Little surprise, thanks to Morfic
- Updated to V9A² to fix SOD and some performance issues
21/05/2011 - V9B
- Upstream sync (CWM recovery 3.1.0.1, better screen colors (kills voodoo color for now and looks awful on my 0516 build, but should be good on latest), GPIO fixes, samsung modemctl...) + small changes on my side for official CyanogenMod repository compatibility
- Voodoo Sound updated to V9 / cleaned voodoo color stuff until it works again
- New cleaner bootlogo based on the one in first post, preferred by most users
- Some additional compilation flags from Netarchy and Zacharias.maladroit (better overall performances + NEON)
- Screen refresh frequency bumped to 72Hz (68Hz effective). It'll uncap FPS to 66 again but seems stabler than before on framerate (the divide/2 behavior happens less)
- Added screenstate scaling script from well.heeled.man as a test (with my kernel's smartass default settings). It should give better sleep power consumption as well as better power efficiency on screen off tasks like music playing etc. by switching to conservative governor.
If you want more information, discuss on this or contribute to enhance it, please come here : http://forum.xda-developers.com/showthread.php?t=1087646

(Updated to fix "no service" issue, but still sucks.. unstable on #12 build, very stable on others but no service)
- Upstream sync (PMEM disabled (gives 339MB RAM now), new RIL, headset fixes...)
- Divider changes for MUCH better stability on 1.2GHz at the cost of a slight decrease on performances
- New branch with Voodoo Color display driver and "old" color settings named "VC"
- Fix for Vibrant no service problem - hopefully
- Small changes on smartass governor for better scalability (reverts some old settings not needed anymore with the screenstate script)
- Glitch logo now in update script too for nanu_x2 to be amazed when installing my kernel
24/05/2011 - V9D TO USE WITH CM7 Nightly build #11 OR LOWER (for i9000, or cappy/vibrant equivalent) AND MIUI ONLY
First "D" revision.. Sound like duty. It's basically a fix of a fix done to make the V9C features available for "stable builds" (considering the i9000 #12 isn't)
- Obviously all the V9C changelog
- Using old RIL to be compatible with builds before #12 for I9000 (--> WON'T WORK with #12 for i9000 or equivalent !)
- Replaced 1.54GHz step by 1.6GHz (1.54GHz step was somewhat useless, too close to 1.5Ghz, and slower overall because of the lower bus speed)
- I can't build Vibrant ATM, the CM7 build system is broken on this device or I'm doing something wrong but I wasn't able to fix it. Any help is appreciated. I'm sorry for Vibrant users I'm screwed.V8
07/05/2011 - V8A - To use with 05062011 or newer CM7 build (useable on MIUI RC8 but you'll lose camera - MIUI needs an update)
- Upstream sync (camera fixes etc.)
- More stability fixes
- Cleanups on OC code (found that 1.2 and 1.3GHz were very unstable compared to earlier releases)
- More work on Vibrant/Captivate. The kernels are now available to download but are untested - for now. Feel free to try and report any problem or if all runs well. If I have enough positive reviews, these kernels will be released in their respective device sections.
11/05/2011 - V8B
Upstream sync only :
- USB switch suspend
- TV out stuff
- Fascinate specifics
- Revert "Got back to previous samsung_modemctl" for 05112011 CM7 build
V7
02/05/2011 - V7A - To use with 05012011 or newer CM7 build and MIUI RC8+ only
- Resurrect Voodoo Color killed by 2.3.4 merge.
- New step for 1.5GHz on top of 1.44GHz (now 9 steps total versus 8 before)
- Forcing 400MHz max when sleeping for added battery life (default = 800). Couldn't detect any side effect.
- New tweaked Smartass governor now default (800MHz min when screen on). Please report your experience
- It seems the smartass governor is not working by default, it will revert to performance >< Please force it to get it to work -> Ok found the problem, I'll update in a min
- Now updated to V7A-2 to fix the governor bug
03/05/2011 - V7B - To use with 05012011 or newer CM7 build and MIUI RC8+ only
- Resurrect Voodoo Color killed by 2.3.4 merge - Again - fully working now
- Fixed sleep of death issue when unplugged
- Switched to LZO compression for better overall speed and reduced boot time
- Tweaked smartass governor more for - hopefully - better battery life and a bit more responsivity
- New voltage and frequency table rewrite as a bonus with now 11 frequencies total
- Stability fixes on 1.5GHz step -> please test and report
- Reverted FPS uncap - at least for now - for two main reasons : more stability on high GPU freqs (1.4GHz and more), and to prevent FPS limit at max/2 (33 when unlocked to 66), limiting overall performances in heavy scenes. I think there's a lack of buffering somewhere.. It will give higher scores on some benchmarks, and lower on others. A better battery life can indeed be expected too.
- Upstream sync
05/05/2011 - V7C - To use with 05032011 or newer CM7 build and MIUI RC8+ only
- Upstream sync (better battery life, reboot recovery, etc.)
- A general stability fix missing from V7 branch added back
- Tiny tweaks on the voltage table
- Big bugfix on the V7 branch (redone from scratch, cleaner)
- Switched to 2011.03 toolchain
- Added some optimization flags, "-mfloat-abi=hard" being one of them (up to 40% performance gains in specific cases)
- Small improvements here and thereV6
WIP
22/04/2011 - V6pre - preview/work in progress of upcoming V6A update *test* :
- Reverted PMEM settings to new CM7 default (317MB - same as V5A)
- Reverted some stability fixes that weren't that stable on some devices, or even prevented some to boot
- New voltage table for a more linear increase, improving stability at default settings
- Switched to Deadline scheduler by default as it appears more stable
- Back to 2010.09 toolchain for speed and efficiency

- Voodoo Sound V8
- Various bugfixes on CPU load and schedulers
- CONFIG_CC_OPTIMIZE_FOR_SIZE disabled for speed
- Lower latency on GPU states switch for stabler performances
- Added a stability fix for voltage change latency when frequency is changing. It should give more stability with high undervolt or big voltage differences between two steps - Please test and report ! (Thanks Zach for pointing that to me)
- Two versions for testing purposes : V6pre-u4 is compiled using GCC 4.5.1 toolchain, and V6pre-u4(alt) is compiled using GCC 4.4.3 one. If you get instabilities on the first one, try the other and vice versa. Please report your findings on that because it was the first stability differences source between my kernel revisions. For information, V6pre-u2 was compiled with 4.4.3, and u3 with 4.5.1.
27/04/2011 - V6pre - update 5 >> 6
- Name changed from "TkGlitch" to "Glitch"

- Int voltage lowered for 1.5GHz step because it did have a bad effect on lower frequencies stability
- GPU power latency back to default - but fixed (100ms)
29/04/2011 - V6B - To use with 04282011 or newer CM7 build only
- New initramfs source to fix compass and update CWM recovery
- 1.5GHz replaced by 1.48GHz for stability
- New voltage table as requested by many users (+25mv on 1200 to 1400MHz steps)
- New interactive governor for better scaling and battery life
- New tweaked smartass governor for testing (pretty bad on CPU benchmarks for some reason, please test how it feels in real world use)

V5
19/04/2011 - V5A - Initial release
21/04/2011 - V5B :
- GPU overclock on 1.3 GHz added (217MHz / +8.5% from default)
- New PMEM settings for more available RAM compared to V5A (now 328MB)
- Stability fixes for all frequencies, needing globally less volts. Results may vary depending on the device
- Switched to Conservative governor by default (still switchable by app). It can feel less responsive coming from idle but more battery saving, and plays better with high frequencies.
- New voltage table. Default settings should be stabler for most devices.
- Switched to 4.4.3 toolchain for added stability on some sensitive devices
Captivate and Vibrant support will come later. It will need more time than expected.
21/04/2011 - V5C : Small update to fix a bootloop issue on some devices.

will try and report, thanks
Tried it out, feels amazing, thanks so much! Yet to try 1.4 though
Sent from my GT-I9000 using XDA App
Thanks a lot, goign to try it soon.
I have a question: what is a stock frequency of GPU and is it possible to control it?
If no, can you release 2 versions: with and without GPU OC?

Click to collapse
The stock frequency for the GPU is 200MHz. It's not possible to control it directly because it's linked to the bus. The bus clock being a fixed value by frequency step.
Up to 1300 MHz, the GPU runs at 200MHz. At 1400MHz it runs @ 233 MHz, and at 1440MHz it runs @ 240MHz.
The bus frequency increase will lead to higher memory bandwidth and a better productivity from the CPU.
A version without GPU OC would mean with lower global performances too on the highest frequency steps, but better stability for some sensitive devices.
I'll wait a bit for more opinions if you're okay, and if some of you wants a stock GPU version i'll do it, no problem
Hm.. after flashing i got boot loop..
I'm on MIUI
Sent from my GT-I9000
What kernel did you use before ?
great
man, you are so cool... bilboas kernel died in development, and platypus is soo lagy, and still autorotation problems... thank you for this, everything looking working great, so far...
looking great on first install. I like it! Thanks.

That's OK because I am not going to OC that high and will keep at 1200 as maximum.
Thank you once again for your efforts.
I have zacharias last kernel can install this one over?

@ mosd Sure you can. His init.d scripts could interfere with stability and/or speed though I don't know. You'll have to tell me, I didn't test that at all ^^

To delete the scripts ? Not needed, you can do that with zach's kernel.
For something else.. hmm.. not needed, you can flash mine directly^^
If I'm on Miui and install your kernel do I still have to install the gpu drivers u put up?

@mosd
If it's the latest MIUI, I don't think so. This driver should already be included.
Thanks for answers man

No problem
Since the gpu oc is linked to cpu oc I suppose it's impossible to make gpu clock higher from 1300mhz..right?cause not all phones clock up to 1400
This kernel is based on teamhacksung's kernel, with updated Linux base to 3.0.42
This kernel is working with every ICS based Rom

newer changelog can be found here:
http://www.hellybean.com/ics.html
changelog 02.08.2012:
- bug fix to bln, to prevent kernel panic in some situations (thx to thalamus)
- switched from deep_idle 2 to idle2 (also thx to thalamus)
- updated kernel to linux 3.0.38
- dockaudio sysfs for captivate and fascinate
- automated symlinking from data to system: if one wants to free up some space at /system, without removing an app completely, just copy it from /system/app to /data/sys-parts/app (create the folder if not there), and reboot. during reboot, the app from system gets deleted, and the app from /data/sys-parts/app gets symlinked to system. this is working for almost every app, but i don't recommend doing this with apps, needed for android to work (framework, media provider, settings,...)
IDLE2 can be enabled with the following command:
echo 0 > /sys/module/cpuidle/parameters/idle2_disabled
IDLE2 can be disabled with the following command:
echo 1 > /sys/module/cpuidle/parameters/idle2_disabled
Stats can be obtained from the standard cpuidle interface, which, for
IDLE2 is located at:
/sys/devices/system/cpu/cpu0/cpuidle/state*/time
where * = 1, 2, 3
changelog 25.07.2012:
- updated recovery (no "sdcard format"-bug anymore, external sd card is named correctly)
- vibrant: hopefully fixed froyo ril
- jellybean: galaxy s settings working now
changelog 22.07.2012:
This kernel is for use with ICS only, if you are looking for a kernel, running on teamhacksung cm10 build, visit my jellybean kernel thread[/url]
- updated kernal base to linux 3.0.36
- updated "block" to linux 3.3
- readded fiops io scheduler (kept cfq this time)
- updated cwm recovery to 6.0.1.0 (please create a new nandroid, because of possible incompatibilities between old/new recovery)
- compiled with linaro toolchain (gcc 4.7.1) and O3 compiler flags
- made uksm scan less often (save cpu time and power)
- at first boot: only delte init.d scripts created by other kernels
- increased usb write performance
- lowered ram and display voltages a little bit
- fixed some bugs related to devil settings (they should stick now after reboot, if set by one of the devil apps)
- support for scripts in /system/etc/shutdown.d (thx to Efpophis)
all scripts placed at /data/local/shutdown.d or /system/etc/shutdown.d get executed at shutdown/reboot
you can use this, to play a shutdown sound for example.
by default 00shutdown gets created, which plays a music file, when it is placed at one of these folders/places
/system/media/audio/ui/shutdown.ogg
/data/media/audio/ui/shutdown.ogg
Click to expand...

- disabled some debugging options
- audio (and for fascinate: camera fixes) by Efpophis+
- patch for improving batterie life by CML
- nfts read/write driver built in (for use with usb host mode)
- reverted refreshrate_mod and gpu_oc mod, as both weren't working
changelog 18.06.2012:
- some changes to load balancing
- added ultra ksm (metioned by zach thx for this my friend)
- readded fiops io scheduler (still experimental and could cause instablilities)
- using snappy compression for zram now (2 times faster, but only 2% less compression)
- added the possibility to change zram size (at /data/local/devil/zram_size, with valid values: 50, 75, 100 and 150 (all in mb))
- fixed the applying of user_min/max freq after reboot
- vibrant: fixed gps
- fascinate: fixed nandroid in cwm recovery
what is ksm? http://en.wikipedia.org/wiki/Kernel_SamePage_Merging_(KSM)
uksm is more optimized and also working for single core systems. using this should give much better ram usage, but at the cost of more cpu usage
############# most probably not working (yet)##############
i have added seperate gpu oc from jt1134's galaxy_tab (to switch between 200 and 250 mhz), but i did not get any improvements in antutu...further tests needed
echo 1 > /sys/kernel/pvr_oc/pvr_oc (for 250 mhz)
echo 0 > /sys/kernel/pvr_oc/pvr_oc (for 200 mhz), no reboot needed
and also have changend default screen refreshrate from 60 to 56, with the possibility to change it:
echo 1 > /sys/kernel/refreshrate/enable (60 hz)
echo 0 > /sys/kernel/refreshrate/enable (56 hz)

changelog 01.05.2012:
- all changes from cm9 stock kernel (including mount points option)
- some fine tuning to deadline and sio
- Devil Idle: limiting bus/ram/gpu speed to 100 mhz for 100-800 mhz cpu freq, while screen off (automatic mode) or always (permanet), both modes automatically reduce the int voltages of the affected freq by 50 mV
- compiled with swap support
- added stratosk's smooth_ui to lulzactive governor (activated by default)
- rest oc_value to 100 while screen off, and back when screen turns on (combined with devil idle automatic, can't be turn on/off without devil idle)
- added posibility for different voltages while screen off (also bundled with devil_idle, with default settings, stock arm voltages are applied, because of live_oc set to 100)
- added the possibility to set freq limits while screen off (min and max freq)
19.04.2012
- even better fix to selective live_oc (last one (in test kernel) generated some overhead)
- fixed sampling rate of ondemand and conservative (have ported mialwe's/stratosk's sleep multipliers)
- new tunables for ondemand and conservativ
sleep multiplier and tunables:
mialwe and stratosk had the great idea, to change the sampling rate of conservative and ondemand governor while display of. for this, he introduced the sleepmultiplier (in his case factor 3). this means, if you set sampling rate to 20000, it changes to 60000 while screen off, and back, when screen on.
for ondemand and conservative:
i have made this multipliers tunable. proper values are between 1 and 5, because one could want a higher multiplier while screen off, if sampling rate is very low while screen on (higher sampling rate means, less checking for work load --> better batterie, worse performance). with this tunables you get better batterie, without making the performance worse while screen on.
two other tunables: up_threshold_min_freq and responsiveness_freq
the first one is a very low threshold while on low freq (by default 40), to make the governor scale up faster, until the responsiveness_freq is reached.
the responsiveness_freq is set to 400000 (400 mhz) by default. while the freq is below this value, up_threshold is the same as up_threshold_min_freq, and freq jumps to responsiveness_freq, with skipping the freq between the actual one and the responsiveness_freq. (conservative governor does not jump up to this step)
responsiveness_freq can be set to values between 100000 and 1400000
up_threshold_min_freq can be set to the same values as the normal up_threshold.
not tunable: while screen off, up_threshold is set to 95, no matter your other settings, to save more batterie.
up_threshold_min_freq is disbaled by default for conservative governor
for lulzactive:
for this governor, i did similar things, but they are not tunable till now.
when screen off:
- inc_cpu_load is set to 90, and back to the original value, when screen turns on
- up_sample_time is set to 50000, and back to the original value, when screen turns on
- down_sample_time is set to 40000, and back to the original value, when screen turns on
other changes:
- fix to touchwake from ezekeel, and another fix from stratosk
- upstream fix to compass
- building for i9000B now, too (big thanks to F4k for the hints by pn )
- removed some typos from recovery
- removed some annoying "no's" and "yes" from recovery in misc menu
- fixed wifi mode switch (pm_fast is the one with better signal)
14.04.2012:
- new b versions (only stock ram) changend to 377 mb, VC version needs the 720p fix from my ftp server. cmc version already patched
13.04.2012:
- updated wifi driver
- added the possibility to switch between wifi PM_Fast and PM_Max mode (Pm_Fast = better signal, PM_Max = better batterie, default is PM_Max)
- user interface to disable fsync (this gives more performace, at the risk of data loss on a crash, taken from ezekeel, so it should be ok ), default is off, to be safe
- fixed voodoo color kernels (these have the VC in their names)
10.04.2012:
- added vibrator intensity control (by mialwe), presets can be changend in recovery
- stock ram version now available (348 mb ram), XL (390 mb), XL_bm (402 mb)
- removed 1080 mhz freq for now
- small correction to touchwake
- small correction to selective live_oc (now the low freq really are not live_oc'ed)
05.04.2012:
- fixed bug in selective live_oc, which caused the target high not taking affect to the highest freq, if highest freq equals target high
- fixed another bug in selective live_oc, which could lead to gpu crashes due to overclocking the ram, but not the cpu freq (for low steps)
- added a switch to change between "normal" and selective live_oc
by changing the live_oc mode while using it, live_oc value is set back to 100, to prevent strange things
- added possibility to set max. freq for boot (in recovery). This freq is set until init.d is executeted (it is automatically set to 1000 at this point, to make sure there are no conflicts with other cpu settings from users)
#Already in the last version, but i forgot about it:
- deep idle fixes from stratosk (many thanks)
- added possibility to underclock by using live_oc (limit is 90 now, which means lowering all freq and bus speed by 10%, to save more batterie when really needed)
03.04.2012:
For now there are three different RAM versions:
- stock mem kernel has 379 mb ram, everything working
- "slim ics" (XL) kernel comes with 390 mb, this is breaking playback of some high resolution videos
- XL_BM is coming with 402 mb ram, but breaking 720p
(while flashing the kernel, the modded rom files are also flashed, so you don't need to flash a new rom to get 379 or 390 mb)
-added new frequency: 1080 mhz (1100 does not like live_oc)
- fixed SmartassV2 for live_oc (after changing live_oc value, you have to change the smartass values, too, but then they automatically apply to the live_oc value (although you can only select 800 mhz in nstools (for example))
- touch recovery with custom devil menu (for some reason it takes a few seconds to load the first time, missing virtual keys is a warning, because there are no virtual keys yet)
-fast charge (thx to chad0989 for this), disabled by default.
you also can use the widget from chad (to place on homescreen) to toggle the fast_charge mode
https://play.google.com/store/apps/d...stchargewidget

- added BLX
- upgraded BLN from V8 to V9 (working for missed calls, blinking or static light, configurabel by using NSTools or BLN Pro App)
- added Intellidemand governor
- added mdnie settings to voodoo color version
- readded deep idle v2 again (I think it is the best/only working one, although
- version with CFS (instead of BFS) now also available (maybe better multitasking and batterie life, but slower)
- removed BFQ I/O Scheduler
- tons of smaller fixes and improvements

- Deep Idle V2 back in
- new Cpu governors: MinMax, Lagfree, Lulzactiv
- LED V2 (you can set blinking by using nstools, also working for missed calls in most cases (sometimes it is not working for missed calls, don't know why at the moment))
- Backlight Dimmer (only LED version): used to turn led backlight of, while screen is on, after defined period of time. Deactivating it, makes your backlight stay on all the time
- I/O-less dirty throttling completely backported from kernel 3.2
- Ext4 with 3.2 patches
- Proportional Rate Reduction for TCP - by Google

How to:
you can change ram setting by doing the following ( to make these settings even stick after power off, you also have to echo the same value to to /data/local/devil/bigmem):
echo 1 > /sys/kernel/bigmem/enable (this gives you xl mem of 391 mb)
echo 2 > /sys/kernel/bigmem/enable (this gives you bm mem of 403 mb (this is breaking 720p))
echo 0 > /sys/kernel/bigmem/enable (this gives you cm9 default mem of 378 mb)
you have to reboot to make changes work
Click to expand...
Click to collapse
With setting this, your desired swap mode gets automatically applied at boot time. For swap, you have to create a swap partition at your external sd card before
echo 1 > /data/local/swap_use (for using swap partition on external sd card, you have to create this partition before)
echo 2 > /data/local/swap_use (for using Zram, no other modifications required)
you have to reboot to make changes active. You can't use swap and Zram at the same time

These are the settings for devil idle:
activate automatic:
echo 1 > /sys/devices/virtual/misc/devil_idle/bus_limit
permanent on:
echo 2 > /sys/devices/virtual/misc/devil_idle/bus_limit
deactivate
echo 0 > /sys/devices/virtual/misc/devil_idle/bus_limit_automatic

to set different voltages while screen off (this only is working, if devil idle automatic mode is activated)
this is an example, how to apply screen_off arm voltages:
echo 1450 1400 1350 1275 1075 975 875 800 > /sys/class/misc/customvoltage/arm_volt_screenoff
this way, it is possible to undervolt while screen off, but overvolt and overclock while screen on
for now, the int voltages can not be changend
Click to expand...
Click to collapse
set freq limits while screen off (min and max freq)
enable the limits:
echo 1 > /sys/devices/virtual/misc/devil_idle/user_min_max_enable
disable:
echo 0 > /sys/devices/virtual/misc/devil_idle/user_min_max_enable
set values to be applied if activated:
echo 100000 > /sys/devices/virtual/misc/devil_idle/user_min
echo 800000 > /sys/devices/virtual/misc/devil_idle/user_max
both are independent from devil_idle, and get applied when screen turns off
by default 100 and 1000 mhz are set.
values which can be put here are all "stock" freq (without live_oc level) multiplied with 1000. live_oc values get applied automatically.

Click to collapse
to set responsiveness_freq, up_threshold_min_freq or sleep_multiplier for ondemand and/or conservative governor, you have to do it like this:
echo VALUE > /sys/devices/system/cpu/cpufreq/ondemand/VARIABLE_NAME
and
echo VALUE > /sys/devices/system/cpu/cpufreq/conservative/VARIABLE_NAME
example:
echo 400000 > /sys/devices/system/cpu/cpufreq/ondemand/responsiveness_freq
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold_min_freq
echo 5 > /sys/devices/system/cpu/cpufreq/ondemand/sleep_multiplier
up_threshold_min_freq is disbaled by default for conservative governor
(to disable it for ondemand you have to set up_threshold_min_freq to 100.

Q: What the hell are all these governors?
A: here you should find the answer: http://forum.xda-developers.com/showthread.php?p=19846297
Q: What's a good setup for live_oc??
A: No one knows. Every phone is different. It seems like the folling setup is running well for some (many?) users. If you get reboots with it, you have to find the setup for yourself.

http://forum.xda-developers.com/showpost.php?p=25578231&postcount=83
Q: What is Touchwake? Can you explain it?
A: With Touchwake, the touchscreen still recognices your fingers, after turning off (for a predefined time (NSTools)). For a detailed explenation, take a look at Ezekeel's thread: http://forum.xda-developers.com/showthread.php?t=1239240
Q: How can I make Voodo Color settings been saved after reboot?
A: You have to use Voodoo Pro App, because of changes between Gingerbread and ICS, and only the Pro app is updated till now.
Q: Which is the best IO Scheduler?
A: I think SIO and V(R) are the fastest.
Q: How can I enable DeepIdle/Live_Oc?
A: You have to use NSTools. You find it on market. It's free.
Deep Idle Questions:
Q: How can I activate the deep idle stats?
echo 1 > /sys/class/misc/deepidle/stats_enabled
Q: What's the meaning of TOP=Off and TOP=On when I look at the Deep Idle status?
A: When TOP=Off is used, the best powersaving state is used. TOP=ON will be shown, when bluetooth or gps are running.
Q: In Idle status I only see TOP=On. What's wrong here? I don't use Bluetooth or Gps.
A: You have to flash the modded framework-res.apk, because ICS does not fully deactivate bluetooth by default. Even if you never use it.
Q: Idle Stats only are showing Idle, but no Deep Idle. Why?
A: An App is preventing the use of Deep Idle. At first, you should try closing the cam, running in the background. Also rebooting should solve this problem.
Q: What is fudgeswap?
A:
Setting this to a very large positive number will indicate swap ought
to be fully used as free (and will slow the system down)
smaller numbers will allow you to put some pressure on SWAP without
slowing the system down as much.
small negitive numbers will allow the system to be faster at the same
minfree level.
default is 512 to give a very little bit of pressure to use some swap
but this can be modified at runtime via:
/sys/module/lowmemorykiller/parameters/fudgeswap
why new thread?
damn it, I'm on CM7....
and I want to try your kernel!
CM7 seems to be the stables and fastest for now :\
A very good changelog
I'll give a try when it's done.
@orenzah : Did you try CM9 or SlimICS (for example) ?
Because, I think ICS is really stable for daily use.
For the new thread, I think it's because, now it's Devil3 and not Devil2 anymore.

Zram is better or swap ?
Scheduler
I just flashed Devil3, thanks. Question though - in devil 2, my scheduler was SIO by default, as listed in the feature list, and I always left it like that. After flashing devil3, it's now CFQ. I haven't run benchmarks yet or anything, but noticed the feature list for Devil3 still says SIO by default. Is the default now changed to CFQ? I'm not sure which is the best scheduler to run - CFQ, SIO or VR? I will benchmark, just wanted to hear recommendation as well.
Tx!

wow new thread
thx for the update for the best kernel

IMHO sio is the best in real life and benchmarks
there is no need for an updated devil.json file right?

A very good changelog
I'll give a try when it's done.
@orenzah : Did you try CM9 or SlimICS (for example) ?
Because, I think ICS is really stable for daily use.
For the new thread, I think it's because, now it's Devil3 and not Devil2 anymore.

Click to collapse
yup, i tried both of them...
slim was faster, but I keep feel something is missing... on smothness and stabling... like temple run is working smother on CM7 with glitch and I can reach such of those freq's of course, another thing it's seems that the battery drain is better on CM7...
if things were changed in the last weeks than maybe I will give another shot

well its difficult to tell: swap kills the SD card eventually (NAND is not meant to do continuous re-writes) , ZRam uses only RAM (so its safe for SD) but generates more CPU usage...

no need, the last one works perfectly!
Coming from Semaphore I'm not quite sure where to select the appropriate memory config for the 391 MB version (there used to be seperate versions available to download but now it's just one version). Can't find it in neither NS Tools or Recovery.
There's also one big issue I'm facing regarding video playback. 720p video playback with the 378 MB kernel is not working at all, with both MoboPlayer (w/ codec) nor the stock player, and that's an MP4 file at that (so no codec should even be required). Any help on that?
Also, Any over clock of any sort (live OC or not), renders MoboPlayer useless and it crashes in the first couple of seconds when I open a video file and it reboots.
Still, props for developing this kernel as I do find it to be slightly faster than Semaphore.

bro did u read the OP
- bigmem values get applied at first boot after power on (if there is a value at /data/local/devil/bigmem, 1 for 391 mb and 2 for 403 mb (the last one breaks 720p)
just go to data/local/devil and creat text file called bigmem then open it if u want Xl ram just type 1 and save file then reboot then u will have 391 ram with patched libs for 720p

Default RamDisk: Ordroid 13.0. Should be good for any sense ROM. Please try to use this without repacking on sense ROMs, or else you will lose these tweaks. (But I can't promise that it would work for yours too.)
RamDisk changes:
Disabled pnpmgr. -> Fix for facebook cap resetting, and 25MHz resetting to 100Mhz.
Removed some crazy boot time settings, locking to quad-core, or 1-core depending on some things.

GPU min. clock is 247 again.
Small fixes.
Default ramdisk is CM10.1 Beta 10.
#198 (Still alpha)
Core clocks changed to safer values.
Seems to fix interactive/gaming issue.
#197(Quite much change...it's better to call this alpha version then.)
Interactive and gaming governors seem to quad-lock this to max freq...better not use them.

Notes/Issues/User guide:
The absolute stable version is 188v4, please consider anything above as a beta.
Use smartmax for daily/battery and gaming for performance/gaming.
If you want extra battery, and you are ready to give up smoothness for it, then use "pmc" governor, more info here.
If you want even more performance then you can use interactive or ondemand with gaming boost.
If you have hiccups in music, use interactive there too.
If too much heat generated during games, cap your CPU to 1-1.2GHz, the performance difference will be minimal, also a safe undervolt (25-50mV) should help a lot.
About UV: CPU VDD should be close to Core VDD, by default there is a 100-300mV(depending on kernel) lock between them. Core minimal voltage is 950 at default. This means even if you set 100mV to any freq, it won't go below 650-850. And this also means, if you UV your GPU, while you have CPU UV, CPU UV that seemed stable can become unstable.
So if you plan on UVing GPU, you should UV that first, and CPU only after that.
I'm not responsible for any damage, this kernel might cause.
Thanks to pabx, maxwen, n3ocort3x, tbalden, kozmikkick, showp1984,TripNRaVeR and everyone who contributed to this kernel.
There might be a 1sec delay after wake one sense roms, before the screen processes touches. It's a S2W thing, if you don't want it, disable S2W.(See below)
Here is an awesome guide about how to get the maximum out of your phone, both in battery and performance
Auto-BLN Issues:
Green led might stuck after removing from charger if there is an unseen notification. Just check the notification to solve.
Green led might not come up after a finished charge.
BLN will not work while charging the phone.

Configuring kernel parameters:
S2W Configs:
Turn off:
Code:
echo "0" > /sys/android_touch/sweep2wake
Or you can download "Sweep2Wake-Widget" from Google Play.
Button panel locks to s2w after this distance:
Code:
/sys/android_touch/s2w_register_threshold
Screen turns on/off after this distance:
Code:
/sys/android_touch/s2w_min_distance
Direction independent(1 - Yes, 0 - No):
Code:
/sys/android_touch/s2w_allow_stroke
DoubleTap2Wake Configs:
Turn on:
Code:
echo "1" > /sys/android_touch/s2w_allow_double_tap
Activate fast charge:
Code:
echo '1' > /sys/devices/platform/htc_battery/fast_charge
Enable smartdimmer:
Code:
echo "1" > /sys/devices/tegradc.0/smartdimmer/enable
To get your variant:
Code:
cat /sys/kernel/debug/t3_variant
(Or see it in a root explorer)
cpu_process_id is your variant.
3D Tuning:
If you want to change clocks, you have to write the whole clock table again, from up to down. In case you want to reset to default, this is it:
Code:
echo '520 520 520 520 492 484 380 247' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
If you want to set them at boot, use an init script. Here is one. Just copy to /system/etc/init.d and set the permissions to executable by everyone with a root explorer. (Thx to Byrana)
Here is a flashable script that will work on newer kernels too for everyone. It also enables fast_charge. (Thx again Byrana)
2D Tuning:
If you want to change clocks, you have to write the whole clock table again, from up to down. In case you want to reset to default, this is it:
Code:
echo '520 520 520 520 492 484 380 247' > /sys/devices/system/cpu/cpu0/cpufreq/two_d_oc
You should NOT OC this higher than 3D.
EMC Tuning:
If you want to change clocks, you have to write the whole clock table again, from up to down. In case you want to reset to default, this is it:
Code:
echo '667 667 667 667 408 408 408 408' > /sys/devices/system/cpu/cpu0/cpufreq/emc_oc
If you want to OC let's say to 800MHz:
Code:
echo '800 800 800 800 667 667 408 408' > /sys/devices/system/cpu/cpu0/cpufreq/emc_oc
Auto-BLN Control:
Interface:
/sys/class/leds/button-backlight/auto_bln
Values:
0: BLN OFF/Green led ON
1: BLN ON/Green led ON
2: BLN ON/Green led OFF
Example:
Turn off Auto-BLN:
Code:
echo '0' > /sys/class/leds/button-backlight/auto_bln
The changes will apply from the next notification.
Backlight button brightness:
Interface:
/sys/class/leds/button-backlight/button_brightness
Values:
0-255: 0 is off, 255 is the maximum possible.
Example:
Code:
echo '50' > /sys/class/leds/button-backlight/button_brightness
The changes will apply from the next backlight turn on.
GPU Voltage control:
If you want to enable this you should write '1' to /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage.
In command line that is:
Code:
echo '1' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage
After that you need to restart your voltage control app (Trickster Mod).
Now you will see the GPU frequencies multipled by 1000 to separate them from the CPU frequencies. So you will see 520000MHz, etc.
Be advised that there are a really few HOX's that can handle more UV on Core, than the preset 50.
Also incrasing your Core voltage over 1300mV is NOT ADVISED AT ALL. Almost everything uses this voltage on your motherboard.
If you want to enable the values at boot, you need an init script that enables it, so later Trickster mod or anything can set them.
LP OC:
Interface:
/sys/module/cpu_tegra/parameters/enable_lp_oc
Values:
0: LP OC OFF
1: LP OC to 620MHz
Example:
Turn on LP OC:
Code:
echo '1' > /sys/module/cpu_tegra/parameters/enable_lp_oc
Audio Min. Freq.:
Interface:
/sys/module/snd_soc_tlv320aic3008/parameters/audio_min_freq
Example:
Change audio min. freq. to 204MHz:
Code:
echo 204000 > /sys/module/snd_soc_tlv320aic3008/parameters/audio_min_freq
Save settings:
If you want any of the above settings saved, you can use iba21's recovery package.

REPACKS(Click)
If your ROM is not in the list, then you should repack yourself, or wait until there is a repacked version out.
You can use this tool to repack the kernel: [TOOL]One X One Click v1.9 then please upload it to d-h.st:
username: xmrepacks
password: xmrepacks
For file name use the following: xm_kernel_<num>_<rom>.img or xm_kernel_<num>_<rom>.zip if you include the modules, for example: xm_kernel_95_viper336.img
And for description use the following: XM-Kernel #<num> for <rom>, for example: XM-Kernel #95 for Viper 3.3.6
Tick to Make it public.
I'm trusting you, that you won't upload anything else than repacked XM-kernels. Please don't fail my expectations.
There is an alternative link for repacked boot images, thanks to Whiskey103: http://www.whiskey103.nl/Onex_kernels/index.php?dir=xm/Repacked/
TODO:
Release the next stable version.

The fix for governor switching has actually nothing to do with OC
So you can just use that without any OC - which we dont really need on HOX+
The only OC I have is enabling of 4x1.7Ghz

Hi,
did you check your mac address ? and the rules on your router ?
1.6.9/cm10.1/aosp all fine without WiFi issue.Maybe it's ROM problem.

dont complaint if sound distorts at loud profile
loud profile is mean for full size cans (headphones) n similar things where you need a little more power
dont switch it on if you are using IEM (in-ear earphones) or normal earphones

msm_mpdecision
show-p1984 said:
What is msm_thermal?
What is msm_mpdecision?
100% kernel based multi core decision! (should cpu1/2/3 be online or not?)
This replaces your /system/bin/mpdecision binary which is renamed by the installer to mpdecision_bck.
Check /sys/kernel/msm_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic
delay = time between checks
pause = if something else plugs in the cpu, fall asleep for 10000ms
max_cpus_online_susp = if the screen is off, how many core should be active when the screen is off
enabled = enable(1) or disable(0) mpdecision. This does not affect max_cpus_online_susp
min_cpus = min cpus to be online, cannot be < 1. Default: 1
max_cpus = max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore) Default: 4
idle_freq = a value against that will be checked if a core +/- is requested. (300000)
If cpu0 is below that value and a core up of another cpu is requested, nothing will happen.
If any other cpu is above that value and a core down of that cpu is requested, nothing will happen. (otherwise it would now put down that cpu even though it is still working, which isn't what we want)
Hot plug thresholds (aka now it gets 'complicated')
This small formula calculates which value will be used: (number_of_cpus_online - 1) * 2
The result of this formula will be the nwns_threshold where a new cpu is hotplugged.
The result of this formula + 1 will be the nwns_threshold where a cpu is unplugged.
nwns_threshold_x = runqueue threshold, if this is reached cpuX will be hot/unplugged
twts_threshold_x = time threshold, this amount of time must have passed for the related action to be taken (hot/unplug)
Example:
One cpu is online.
(1 - 1) * 2 = 0 ergo:
nwns_threshold_0 = cpu1 will be hotplugged at this value
((1 - 1) * 2) + 1 = 1
nwns_threshold_1 = cpu0 will be unplugged at this value
Since we can't unplug cpu0 this is '0'.
Two cpus are online.
(2 - 1) * 2 = 2 ergo:
nwns_threshold_2 = cpu2 will be hotplugged at this value
((2 - 1) * 2) + 1 = 3
nwns_threshold_3 = cpu1 will be unplugged at this value
etc...
Some values are:
NwNs_Threshold: 12, 0, 25, 20, 32, 28, 0, 35
TwTs_Threshold: 140, 0, 140, 190, 140, 190, 0, 190
Where the position and function of the number equals the result of the above explained formula.
(all times are in ms)
If you want to see the mpdecision magic happening:
Code:
adb shell
cat /proc/kmsg | grep 'MPDEC'
mpdecision's input event boost, aka project butter
This will boost your min cpu speed if you touch the screen or press a button and gives you full control.
In those events the min cpu freq will be risen to a predefined value (look below) on every online cpu. This boosts overall reaction times and smoothness a lot. (works similar to the qcom mpdecision binary)
Configuration files:
[email protected]:/sys/kernel/msm_mpdecision/conf # ls | grep boost
boost_enabled
boost_freqs
boost_time
All of them work like the usual sysfs files, except one special case:
boost_freqs will list all frequencies from cpu 0 to cpu x. Cpu 3 and any following cpu will share one frequency.
To change those frequencies echo the cpu number + the frequency in khz.
Example: To change the boost freq of cpu3 (and 4,5,6,7,8, etc) the echo would look as follows:
Code:
echo "3 960000" > /sys/kernel/msm_mpdecision/conf/boost_freqs
for cpu0:
Code:
echo "0 960000" > /sys/kernel/msm_mpdecision/conf/boost_freqs
Defaults:
Code:
cat /sys/kernel/msm_mpdecision/conf/boost_freqs
960000
960000
729600
576000
Why do I have no WLAN?
Due to this kernels very high optimization settings it is too big for our boot.img with WLAN included into the kernel, so it is built as a module. That means it needs to be inserted into the kernel upon boot up, which needs to be automated for maximum comfort.

enabling n disabling a hotplug is simple
1 = enabled
0=disabled
to disabling a hotplug here is a example via terminal
Code:
echo "0" /sys/kernel/msm_mpdecision/conf/enabled
you can use third party apps too to make it a macro
i like aero kernel control available in the playstore
goto misc settings
tap "+" sign
navigate to the path you want n set the parameter as a macro
msm_hotplug
enabling n disabling msm_hotplug
/sys/module/msm_hotplug/enabled
other parameters
/sys/module/msm_hotplug/
msm_mpdecision
enabling n disabling the msm_mpdecision
/sys/kernel/msm_mpdecision/conf/enabled
other parameters
/sys/kernel/msm_mpdecision/conf/
intelli_plug
enabling n disabling the intelli_plug
/sys/module/intelli_plug/parameters/intell_plug_active
other parameters
/sys/module/intelli_plug/parameters/
MAKE SURE YOU DISABLE THE OTHER HOTPLUGS BEFORE YOU ENABLE ONE
if you enable intelli_plug make sure bricked_hotplug and msm_hotplug are disabled
if you enable msm_hotplug make sure bricked_hotplug n intelli_plug are disabled
bricked_hotplug is enabled by default as i feel its the best daily driver for max sot n battery life without compromising on performance
The zip adds module insertion to your ramdisk, if that fails for some reason the wlan module cannot be inserted.
if
Code:
adb shell lsmod
doesn't show this:
Code:
tun 14701 0 - Live 0x00000000
cifs 275399 0 - Live 0x00000000
bcmdhd 2964650 0 - Live 0x00000000 (C)
Then something went horribly wrong.
Chances are that I broke it and this should never happen.
One post in the issue tracker will probably fix it with the next release
You can restore wlan for your current bootup by executing:
Code:
adb shell
su
insmod /system/lib/modules/bcmdhd.ko

Flashed it on cm11 RC16 for now, everything seems swift and smooth for now. Gonna leave more feedback soon on CM11 RC16.
Tomorrow I'll move to carbon RC6, will provide more feedback then.
Now, I'm gonna go and play around with the settings. Heh.

So, I played around with some settings and I found a bug. Sweep2Sleep (Also Sweep2Wake) isn't properly implemented, neither is it working nor are its settings proper. https://app.box.com/s/q58sztnn0y8eizuu0go99jlizyngnn3m
Edit : So, I tried the wake settings in trickster mod and when I selected s2w+s2s then s2s is working but s2w is just not working, I tried swiping in many ways, many many times but Its just not working. Also, if u select just s2s then it just reverts back to s2w+s2s probably because s2s isn't working.
I did a standard test I do with all kernels that I try (I have tried all the latest versions of all kernels that are currently available), I close every app that is running in background using greenify, CPU is set to 1.6ghz - 300 MHz, intelliplug (eco mode disabled in urs, no other has eco mode, I use mp-decision on those which doesn't have intelliplug), on demand governer, GPU set at Max (550 on urs and beast kernel and 450 on others) and I play a 720p hevc video, on ur kernel i was getting the smoothest playback among all (It was lagging for the least amount of time, same lag times as beast kernel, so might be just cause of OCd GPU). But in any case, currently this kernel is the best performing and feature rich kernel available. Period.
I'll try other settings (especially eco mode), and will leave further feedback soon.
Thanks, I await further updates. Loving the increasing amount of kernels on our forums.

What do u mean by 'Documentation' ? If u inferring that I didn't read the OP, then I'll inform that I properly read it before flashing the kernel, it says nothing about this. I did notice that the feature list says 'Sleep 2 Sleep' instead of 'Sweep 2 Sleep' but nothing else. What am I missing here, buddy ?

I know that, S2W isn't working in any case.
Great Work.
Using this kernel currently with CM R16, everything is working fine.
Battery life is excellent for me. After nearly 15h - there is still 72% battery left. Usage: Screen on: 30 min, Wifi, Bluetooth always enabled.
Only thing so far is that Netflix is not working, but this might be totally Rom related, as it was also not working with the orginal kernel.

NOTES & INFORMATION
Electroactive governor
The Electroactive CPU governor has been created to get some of the best balances between battery life and performance that you will see on a device. It is a hybrid class governor, using a unique way to merge the best of both interactive and ondemand. It includes some extra additions and enhancements to be more battery saving than interactive governor and some boost tunes and additions that allow better power management and performance in games as well as better power saving when in normal use. CPU boost, graphics boost, fast_start deep_sleep and detection features are built in as well as 300 MHz clock speed in suspend. This governor performs extremely well in games, normal use, battery performance, and just about everything. Some tunables available in the governor:
boostpulse: Immediately boost speed of all CPUs to hispeed_freq for min_sample_time, after which speeds are allowed to drop below hispeed_freq according to load as usual.
boosted_sampling_down_factor: This custom made parameter's set default setting will give several 0.4 second bursts of full throttle CPU to programs. It's about the time that user interface has to produce some meaningful response to your input so to feel smooth, especially while gaming. Besides better responsiveness, this setting will also give better overall speed to many programs which often interchange high CPU demand with IO waits and then suffer because the CPU governor too eagerly throttled down the frequency during those waits.
default_freq_boost_time: this is the default time that the CPU will spend in 'boost mode' before scaling down to normal frequencies, such as when in normal use.
ui_sampling_rate: when you touch the screen, the sampling rate changes temporarily to whatever you set it to.
down_differential: After spending sampling_down_factor*sampling_rate micro seconds at maximum frequency on high load, governor samples the load again to calculate an approximate targeted frequency to scale-down-to which should not trigger up_threshold in the next sample. (Triggering up threshold may cause jumping to max frequency again). Max_load_freq is checked against (up_threshold - down_differential) * current frequency. If found to be smaller, CPU is scaled down to a target frequency as described above. Down_differential also act as the factor to prevent aggressive scale down. Higher value of down_differential corresponds to delayed scaling down.
two_phase_frequency: Two-phase is a battery saving technique where even during max cpu frequencies, there are still gaps of inactivity so instead of running @ max frequency all the time, the two phase will alternate between busy/idle phase. Accepts four frequency values separated by comma, for cores 0, 1, 2, and 3.
input_event_min_freq: takes four values separated by comma. These are the input boost frequencies for cores 0, 1, 2, and 3.
input_event_timeout: this is the length of time in milliseconds that the input boost will be active (default 500). Setting this to 0 disables input boosting.
powersave_bias: this parameter takes a value between 0 to 1000. It defines the percentage (times 10) value of the target frequency that will be shaved off of the target. For example, when set to 100 -- 10%, when ondemand governor would have targeted 1000 MHz, it will target 1000 MHz - (10% of 1000 MHz) = 900 MHz instead. This is set to 0 (disabled) by default. When AMD frequency sensitivity powersave bias driver -- drivers/cpufreq/amd_freq_sensitivity.c is loaded, this parameter defines the workload frequency sensitivity threshold in which a lower frequency is chosen instead of ondemand governor's original target. The frequency sensitivity is a hardware reported in a value between 0 to 100% that tells software how the performance of the workload running on a CPU will change when frequency changes.
ignore_nice_load: this parameter takes a value of '0' or '1'. When set to '0' (default), all processes are counted towards the 'cpu utilisation' value. When it's set to '1', the processes that are run with a 'nice' value will not count aka ignored in the overall usage calculation. This is useful if you are running a CPU intensive calculation that you do not care how long it takes to complete as you can 'nice' it and prevent it from taking part in the deciding process of whether to increase your CPU frequency.
freq_for_responsiveness: up threshold considered for sampling load is up_threshold_at_min_freq. Also during the part where CPU is at maximum load frequency, governor need to find the optimal frequency as the next frequency - which should not trigger up_threshold in the next sampling. When such a frequency_next is found to be a) less than freq_for_responsiveness b) will not trigger down_threshold in the next sample, then the optimal frequency is set to freq_for_responsiveness.
Electroactive Configuration File
Kernel defaults are used to build a configuration file, based off of elementalx's original config file. The config file is found at /etc/electroactive.conf. You can edit this file to change kernel settings. Whatever is set in this file will take effect when the device is booted (unless other scripts or apps interfere).
If settings are not sticking:
Make sure you have busybox installed correctly and updated to the latest version
Make sure the file permissions for /sbin/electroactive.sh are set to execute.
Check to see if any scripts or apps are interfering with your settings.
To execute the script file:
Install Terminal Emulator from the Play Store if you haven't already and open it.
In the emulator type: "su" and press enter
Type: "cd sbin" and press enter
Type: "sh electroactive.sh" and press enter
The values should now be applied, with no need to reboot
As always, you can also edit the values using the Synapse app or reboot to apply.
fsync
fsync can be disabled if you're looking for the last ounce of performance. If you disable it however there is a slight risk of data loss if your phone shuts off unexpectedly before the filesystems are synced.
Max screen off frequency
The default max screen off frequency is 1190MHz, which is a good balance between limiting the voltage/frequency and the time required to complete tasks while the screen is off. This can be changed manually at /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_freq
NTFS and exFAT support
This is for anyone who wants to use OTG cable to connect a USB stick or portable hard-drive formatted with Microsoft's NTFS or exFAT filesystems. (Useful for installing and transporting files from your device) You will need Stickmount or a similar app
F2FS support
F2FS support is built into the kernel. No need to flash any other support patches before installing Electroactive.
Color preset
Some users complain that the Nexus 5 screen has too 'warm' colors, so there are two color presets: stock and slightly cooler. You can edit /etc/electroactive.conf to change the setting on boot.
/sys/module/mdss_dsi/parameters/color_preset
0 = stock color
1 = slightly cooler color
Sweep2wake (flar2)
Sweep2wake allows you to turn on your phone by swiping your finger across the screen. There are four sweep actions that will work
Gesture........Value
Sweep right......1
Sweep left........2
Sweep up.........4
Sweep down....8
Add up the values for each gesture you want to enable and put the total in /sys/android_touch/sweep2wake. For example, to enable all gestures, the value is 15 (1+2+4+8). To enable sweep right, sweep left and sweep up, the value is 7 (1+2+4)
/sys/android_touch/sweep2wake
Doubletap2wake
DoubleTap2Wake (DT2W) allows you to wake the device by double tapping anywhere on the screen. This causes significant battery drain, so you choose at your own choice if you want it enabled or not. You can edit /etc/electroactive.conf to change the setting on boot.
/sys/android_touch/doubletap2wake
0 = disabled
1 = enabled (bottom of screen only)
2 = enabled (full screen)
Sweep2Sleep
Sweep2Sleep allows you to put the device to sleep by sweeping your finger across the navigation bar area. You can choose different directions to swipe. Unlike Sweep2wake, this does not cause any battery drain. You can edit /etc/electroactive.conf to change the setting on boot.
/sys/android_touch/sweep2sleep
0 = disabled
1 = sweep right
2 = sweep left
3 = sweep left or right
Backlight dimmer
Backlight dimmer allows you to adjust the LCD screen brightness lower than is possible with stock. You can edit /etc/electroactive.conf to change the setting on boot.
/sys/module/lm3630_bl/parameters/backlight_dimmer
0 = disabled
1 = enabled
USB fast-charge
This will allow you to charge at a faster rate when connected to a USB port. The default limit for USB ports is 500ma, this increases it to 900ma. This only works on laptops/desktops/any computer but not the phone's charger. You can edit /etc/electroactive.conf to change the setting on boot.
MSM Thermal-X Driver Options
MSM Thermal-X will throttle your cpu speed to keep it cool and unleash it if the cpu has cooled down enough. The input-event boost will temporarily boost the cpu frequency to prevent any lag while not hogging up battery.
Check /sys/kernel/msm_thermal/conf/ for the thermal configuration
allowed_max_high = highest threshold (phase 3)
allowed_max_low = remove the throttling if we cooled down to this (clr_thrshold)
allowed_max_freq = max frequency if throttled (limit)
[...]mid[...] = same as above, just for phase 2
[...]low[...] = Lowest threshold (phase 1)
check_interval_ms = how often shall we check? (sampling rate)
shutdown_temp = if we reach this shut down the device!
MSM MP-Decision Hotplug Options
MP-Decision Enabled
Enables/Disables the hotplug. On disabled the backup cpu-control will be stock Qualcomm mp_decision
# 1 for enabled
# 0 for disabled
echo "1" > /sys/kernel/msm_mpdecision/conf/enabled
Touch Boost
Touch-boost will temporarily raise cpu_min to a frequency determined by an mp_decision algorithm.
# 1 for enabled
# 0 for disabled
echo "1" > /sys/kernel/msm_mpdecision/conf/boost_enabled
Idle Frequency
If the first core is below this frequency, then don't plug the other cores.
echo "300000" > /sys/kernel/msm_mpdecision/conf/idle_freq
EcoMode
Ecomode tries to limit cores to just 2 unless there is a very heavy workload in which cores 3 and 4 are temporarily brought online and won't kick on until both CPUs are maxed out then it will allow for all 4 cores to come temporarily online.
echo "99" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_4
StrictMode
Strict mode functions so only 1 CPU tries to be online at first before bringing up cpu1 and cpu2 online.
echo "85" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_2
echo "99" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_4
Max CPUs online
Max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore).
echo "4" > /sys/kernel/msm_mpdecision/conf/max_cpus
Min CPUs online
Min cpus to be online, cannot be < 1.
echo "1" > /sys/kernel/msm_mpdecision/conf/min_cpus
Screen-off Single core
If the screen is off, don't plug in cpu1/2/3. Additionally: Unplug all cpus except cpu0 when screen is turned off.
echo "1" > /sys/kernel/msm_mpdecision/conf/scroff_single_core
Pause
If something else plugs in the cpu, i.e. CPU-Governor or Thermal, fall asleep for <#>ms.
echo "10000" > /sys/kernel/msm_mpdecision/conf/pause
StartDelay
Time until mpdecision starts to work.
echo "20000" > /sys/kernel/msm_mpdecision/conf/startdelay
Delay
Time between checks.
echo "130" > /sys/kernel/msm_mpdecision/conf/delay
Hot plug thresholds
This formula calculates which value will be used: (number_of_cpus_online - 1) * 2
The result of this formula will be the nwns_threshold where a new cpu is hotplugged.
The result of this formula + 1 will be the nwns_threshold where a cpu is unplugged.
nwns_threshold_x = runqueue threshold, if this is reached cpuX will be hot/unplugged
twts_threshold_x = time threshold, this amount of time must have passed for the related action to be taken (hot/unplug)
Example:
One cpu is online.
(1 - 1) * 2 = 0 ergo:
nwns_threshold_0 = cpu1 will be hotplugged at this value
((1 - 1) * 2) + 1 = 1
nwns_threshold_1 = cpu0 will be unplugged at this value
Since we can't unplug cpu0 this is '0'.
Two cpus are online.
(2 - 1) * 2 = 2 ergo:
nwns_threshold_2 = cpu2 will be hotplugged at this value
((2 - 1) * 2) + 1 = 3
nwns_threshold_3 = cpu1 will be unplugged at this value
echo "#" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_X
echo "#" > /sys/kernel/msm_mpdecision/conf/twts_threshold_X
etc...
Some values are:
NwNs_Threshold: 12, 0, 25, 20, 32, 28, 0, 35
TwTs_Threshold: 140, 0, 140, 190, 140, 190, 0, 190
Where the position and function of the number equals the result of the above explained formula (all times are in ms).
INSTALLATION
If you come from another kernel, dirty-flash your ROM first without wiping any data
If you are an F2FS user, flash the F2FS support patch found below
Flash Electroactive kernel in recovery
Reboot
*F2FS users:
THIS KERNEL USES YOUR RAMDISK, it will just modify it on the fly while flashing. These changes are so to not create any incompatibilities with ROMs or other kernels. Some things to consider when using F2FS:
Use F2FS in only r/w partitions (/data and /cache).
F2FS in /system does not make any difference and requires selinux to be set to permissive, and Electroactive kernel is enforcing by default, although you can change this in the .config file found in /etc/electroactive.conf, but is still not recommended.

Feature Requests
If anyone wants any feature requests, please post them in the feature requests tab at the top of the page. I will try my best to add the most features that I can without sacrificing stability or performance.
Seems stable und fast so far, pretty good work ... A few governors for my taste to much, but the default one is a beast

Thanks,
If you have any features you want me to add to my kernel them feel free to ask.
Everything is fine, unleashed kernel uses alucard hotplug, this would be an unique feature

Good to know that msm_sleeper is a hotplug... I think u missing the all thing.
Hi Electrex,
1st thanks for your awesome work!
2nd your kernel is ukm compatible? (or trickster or elementalx app?)
Tia!
Trickster works fine but due to the config file you did not need such apps

Yes, in the description, I posted all of the compatible kernel managers. I'll put them here too, as my OP is a bit cluttered:
Compatible with ElementalX Kernel app, TricksterMOD, Device Control, Kernel Tweaker, Franco Display Control, FauxSound Control, and Synapse Kernel manager.
You can also edit the .config file in /etc folder without an app to change kernel settings.

Hello,
This is a really nice piece of work, the responsiveness is excellent and battery life is great! Using stock settings. Has all the features i need.
Thank you for sharing your work with us!
Ok so does it work on cm 12 based roms? Blisspop and all?
i'm using "Semaphore Manager" is that okay??
maybe i'm missing on features.

Yes, it works on any 5.1 Lollipop ROM and ONLY 5.1 lollipop versions. Do not use this build for earlier versions of lollipop.
Your kernel is blazing fast and rock solid the last days. Cool project
Bricked Cataclysm
I agree. Great work!
