This kernel extends the CM kernel with some new features:
New init.d scripts to allow some tweaking without needing any 3rd party apps
* See the next post for details.
Replaced HTC's mpdecision with a new custom hot-plug driver that I created:
* This hot-plug driver is more aggressive about bring cores on and off-line to match the load on the system.
* Bringing cores online earlier makes your phone more responsive / smooth.
* Taking cores offline earlier improves battery life.
* It ramps up very quickly on resume to avoid lag.
Replaced HTC's lightsensor table with one that is more sensible and that matches what other devices use. If you have custom auto-brightness settings, you'll probably need to tweak them after installing this kernel.
There are many additional changes to boost performance and battery life:
* Linaro -O3 compiled (Linaro 4.8).
* Overclocking
* I disable tons of HTC debugging crap left enabled and needlessly consuming battery.
* Improvements to the core locking code of the kernel.
* Patches that transform traditional locks into RCU backed data structures.
* CAF version of the ondemand
* CAF changes to power management to sleep faster and waste less CPU during suspend.
* Improved code for moving data to/from user-space and manipulating strings within the kernel.
Other features:
* Voltage control (faux123) to allow user-space under-volting.
* BFQ I/O scheduler.

Version 4.0.12: September 9, 2013: First release
init.d tweaks
I created some scripts that run on boot (init.d) because I install my kernel so many times that I would go insane if I had to use an installer to configure it each time. By using these scripts and configuration files on the sdcard, I can just configure it once and keep installing away to my heart's content.
After installing this kernel, there will be:
/system/etc/init.d/99crpalmer
run at boot, even if you switch to another kernel. It is safe to leave this file there and to let it run as it only makes changes if the kernel contains "crpalmer" in the version. If run with a kernel that contains crpalmer in the version, it will rename mpdecision so it can't run. If you install another kernel it will then rename mpdecision back so that it will run in the new kernel. In addition to stopping the built-in mpdecision it will allow the following tweaks:
CPU Frequencies
* Frequencies loaded from /sdcard/crpalmer-cpufreq-min and /sdcard/crpalmer-cpufreq-max
* Governor loaded from /sdcard/crpalmer-cpufreq-governor
* If you specify either or both of these frequencies, it will lock down all of the CPU frequency controls. I had to do this because HTC overrides them in a script that is run very late in the boot process (thanks HTC!).
* E.g. adb shell su -c "echo 192000 > /sdcard/crpalmer-cpufreq-min"
* E.g. adb shell su -c "echo 1728000 > /sdcard/crpalmer-cpufreq-max"
* E.g. adb shell su -c "echo interactive > /sdcard/crpalmer-cpufreq-governor"
Undervolting
* + or - value loaded from /sdcard/crplamer-uv
* The undervolting in 2.0.23 for FAST binned CPUs would be specified as:
* E.g. adb shell su -c "echo -100 > /sdcard/crpalmer-uv"
Lightsensor
* My light sensor changes didn't sound like they worked well for everyone. If you don't like them you can disable them by:
* E.g. adb shell touch /sdcard/crpalmer-stock-lightsensor
HTC Colour "Enhancement"
* If this file is present then the HTC's colour "enhancement" will be used, otherwise it will be disabled.
* If this file contains the string "m7" then it will use one of the colour enhancement that was used in the M7 kernel for a panel most like ours.
** E.g. adb shell touch /sdcard/crpalmer-color-enhancement
My WIFI Won't Turn On
If your WIFI won't turn on then the most likely cause is that either you didn't flash the boot.img (e.g. not S-OFF) or your modules don't match the kernel. To figure out what's wrong, first boot the ROM after having installed my kernel. Second, verify that you are running my kernel by running
adb shell cat /proc/version
and seeing that it says crpalmer in (it should match the version that you think you installed, but at least saying crpalmer is a good start). Then do:
adb shell dmesg -c
(turn on wifi)
adb shell dmesg
and look for an error that says crpalmer in it (something like a module version mismatch error). If you see that, it should tell you the version number of the modules that are installed and the version of the kernel.
reserved
Note for those of you used to an existing kernel of mine.
This kernel involves reporting all of my changes to a new base. As such, it is likely to have some issues at the moment. Please let me know if something isn't working right.
This kernel is based on Linux 3.4.10 and not the latest 3.4 Linux kernel. I may change that in the future, but for the time being it makes it easier to try to move code to and from the CM repos to leave it at 3.4.10 and therefore I won't be changing that for now.
This kernel does not contain my thermal driver. I haven't spend the time to port it to this kernel yet and the stock seems to be working a lot better than the DNA one. Therefore, I may never bother porting it.
This kernel does not contain force fast-charge. I may add it again the future.
This cant work on the latest unofficial CM correct?

Not sure how relevant this is to folks, but my phone's running PPSSPP games, most noticeably Dissidia 012, much better with this kernel and CM10.2 than it was with the 4.3 roms from about a week ago.
I just posted a new release. I have been completely flicker free today running this kernel. It could be a fluke, but at the moment I am (once again) optimistic that we might have a solution.
If you have bad flickering on CM ROMs, can you let me know how this version works for you?
Version 4.1.1: September 10, 2013: GPU / Display / Clocks / Flicker?
* Synch the GPU code with the M7 / upstream
* Make the display code more inline with the M7 / upstream, use the proper late_init ./ early _off interface
* Add missing clocks
* These changes (most notably the clocks change) may have improved the screen flickering (only time will tell).
I see you added smartmax governor. I've never used it have you? Just wondering.

That'd coming from the stock kernel. I haven't played with it at all.
This kernel is amazing so far; it fixed the wonky boot image thingy, and most of my flickering is gone as well, and mine was pretty bad occasionally. Lets see if it holds tomorrow. Only other thought is maybe USB OTG, but thanks CrPalmer.
Rock solid on my device, but I've never had very bad flickering (knock on wood). Thanks for the great work!
Thanks, could please fix the autofocus of the camera that does not work!
Any positive or negative reports on the flickering with 4.1.1?

Did you have a lot, a little, some flickering on older kernels? How long have you been running it?
Been running cyan since day of release and both Ur kernels for 4.3 l since u put them out a few days ago ... Had slight flickering nothing hard core like some had reported could see it more in bright light but seems to have almost totally took care of mine ...

The goal of this kernel is above all stability with the secondary goals of increased performance and increased battery life. I use this phone for several hours a day for work and therefore it must be reliable. I am not focusing on providing a million options for governors, etc. In addition to those main goals of the kernel, I have an additional secondary goal of removing as much HTC code as possible from the kernel.
This is based on the 2.04 kernel source release from HTC with a huge number of modifications. Thanks to faux123, showp, harsh, mdeejay, zarboz and dsb9938 whose kernels I have pulled some commits from.
The unique features of this kernel are:
New init.d scripts to allow some tweaking without needing any 3rd party apps
* See the next post for details.
Replaced HTC's mpdecision with a new custom hot-plug driver that I created:
* This hot-plug driver is more aggressive about bring cores on and off-line to match the load on the system.
* Bringing cores online earlier makes your phone more responsive / smooth.
* Taking cores offline earlier improves battery life.
* It ramps up very quickly on resume to avoid lag.
Replace HTC's thermald with a new custom thermal driver that I created:
* Unlike all other thermal drivers, it uses "trip-points" to let the phone tell the kernel when it is overheating. The other thermal drivers poll every X ms and read the temperature instead.
* By using trip-points, there is 0 battery consumption unless the phone is overheating.
* By using trip-points, there is an instant reaction to temperature changes.
* It's probably nearly impossible to cause thermal shutdown without being in a desert!
Replaced HTC's bluetooth drivers with Code Aurora Forums (CAF) version.
Replaced HTC's lightsensor table with one that is more sensible and that matches what other devices use. If you have custom auto-brightness settings, you'll probably need to tweak them after installing this kernel.
There are many additional changes to boost performance and battery life:
* Linaro -O3 compiled (Linaro 4.8).
* Overclocking from mdeejay's kernel.
* Underclocking to 192MHz.
* I disable tons of HTC debugging crap left enabled and needlessly consuming battery.
* Improvements to the core locking code of the kernel.
* Patches that transform traditional locks into RCU backed data structures.
* CAF version of the ondemand and conservative governors.
* hsic wakelock changes from dsb9938's kernel.
* CAF changes to power management to sleep faster and waste less CPU during suspend.
* Improved code for moving data to/from user-space and manipulating strings within the kernel.
Other features:
* Include all mainline Linux changes to keep up-to-date on bug fixes.
* Voltage control (faux123) to allow user-space under-volting.
* BFQ I/O scheduler.
* CAF lowmemorykiller.
* Force fast charge.

Changelog from 1.2.x
Version 1.2.6: April 4, 2013: ramdisk fix, lowmemorykiller, hsic wakelocks:
* Fix a problem where the ramdisk was no longer disabling mpdecision and thermald. This issue causes a very minor additional battery drain that has now be fixed (Thanks t1gartist!).

* Bluetooth drivers are the current CAF msm-3.4 drivers.
* Additional CPU speed and governor information added in /proc/cpuinfo.
* Cleaner patching to upstream linux (see my github repo for the clean upstream patching).
* Linaro -O3 compilation was redone from scratch because there were some problems found by kern3l in the original patches I pulled, I wanted to ensure that there were no other problems so I redid the work myself.
Changelog from the 1.0.x series:
1.0.27: Mar 25, 2013: thermald, simple_plug
* Make the previous changes to simple_plug less aggressive about turning cores back off when applications force them online. We now detect that this has occurred and give the application 2 minutes to be in charge before we force the state back to what we want.
* Change thermald default throttling to be slightly less strict.
1.0.25: Mar 21, 2013: Linux 3.4.37, simple_plug, performance
* Linux 3.4.37
* simple_plug: add a verify mode (every 5 seconds => almost 0 cost) that fixes the state when apps bring cores on/off-line (e.g. kernel tuner).
* rwsem performance improvements
* CAF improvements (correctness, performance) of the power management layer
1.0.21: Mar 16, 2013: Linux 3.4.36

* Linux 3.4.34.
* Linaro 4.7: stopped using 4.8 beta builds due to stability fears and lack of apparent benefit from it. The latest 4.7 drop back-ports some optimizations anyway.
* lowmemorykiller: switch to the CAF version of the low memory killer.
* Fixed several bugs in HTC's thermal driver that could cause the termal driver to miss thermal events.
1.0.15: Feb 26, 2013: Battery optimization, performance, thermal & hotplug improvements
* governor: make ondemand the default governor
* GPU: Very minor GPU overclock to 487MHz (from mdeejay).

* Turn off all the kernel code that was polling to compute the state needed for thermald / mpdecision.
* Turn off a bunch of HTC statistic collection and debugging that isn't needed and wastes battery.
* Linux 3.4.33: fixes a kernel memory corruption/hang in all 3.0 and 3.4 kernels
* Sparkco's 4.8 Linaro build is now being used to compile the kernel
* Moved to update.zip format with less commonly used modules moved to loadable modules.
1.0.8: Feb 19, 2013: Switch to different OC values
* Now using mdeejay's over/unclocking (hopefully solving the L2 cache corruption panic).
* thermal driver is less aggressive about throttling the phone with an additional early step down to stock speed
(50C => 1.5GHz, 75C => 1.3GHz, 83C => 918MHz, 90C => 384MHz).
* Linux 3.4.32 (although no changes that would affect our phone).
1.0.7: Feb 15, 2013: thermal driver no longer polls for state
* Linux 3.4.31.
* Now using the 2013-01 build of the Linaro toolchain.
* Major rewrite of the thermal driver to remove polling (now uses essentially no power).
* Tweaks to the hot-plug driver to reduce CPU consumed to reduce power consumed.
1.0.5: miscellaneous optimizations
* Optimization: use optimized memcpy for user-space copies
* Update to linux 3.4.30
* Tons more cleansing of excessive debugging output
* Use RCU_FAST_NO_HZ as caf claims to have found that this improves battery life
* More linaro -O3 fixes from kern3l via dsb
1.0.2
* cm3629 driver, removed power button pocket check (sounds like a good idea, doesn't work and is a likely candidate for an infrequent sensor drain coming from the proximity sensor not turning off).
* cm3629 remove some unused functionality.
* Two small fixes from kern3l via dsb9938's kernel.
* clean some log messages.

init.d tweaks
I really like Zarboz's goal of trying to get rid of the need for 3rd party apps to make the common changes that we want to make to some of the configurable parameters of the kernel. I created some scripts that run on boot (init.d) because I install my kernel so many times that I would go insane if I had to use an installer. By using these scripts and configuration files on the sdcard, I can just configure it once and keep installing away to my heart's content.
After installing this kernel, there will be:
/system/etc/init.d/99crpalmer
run at boot, even if you switch to another kernel. It is safe to leave this file there and to let it run as it only makes changes if the kernel contains "crpalmer" in the version.
The tweaks are:
CPU Frequencies
* Frequencies loaded from /sdcard/crpalmer-cpufreq-min and /sdcard/crpalmer-cpufreq-max
* Governor loaded from /sdcard/crpalmer-cpufreq-governor
* If you specify either or both of these frequencies, it will lock down all of the CPU frequency controls. I had to do this because HTC overrides them in a script that is run very late in the boot process (thanks HTC!).
* E.g. adb shell su -c "echo 192000 > /sdcard/crpalmer-cpufreq-min"
* E.g. adb shell su -c "echo 1728000 > /sdcard/crpalmer-cpufreq-max"
* E.g. adb shell su -c "echo interactive > /sdcard/crpalmer-cpufreq-governor"
Undervolting
* + or - value loaded from /sdcard/crplamer-uv
* The undervolting in 2.0.23 for FAST binned CPUs would be specified as:
* E.g. adb shell su -c "echo -100 > /sdcard/crpalmer-uv"
Lightsensor
* My light sensor changes didn't sound like they worked well for everyone. If you don't like them you can disable them by:
* E.g. adb shell touch /sdcard/crpalmer-stock-lightsensor
HTC Colour "Enhancement"
* If this file is present then the stock colour "enhancement" will be used, otherwise it will be disabled.
* Introduced in kernel 2.0.41.

My WIFI Won't Turn On
If your WIFI won't turn on then the most likely cause is that either you didn't flash the boot.img (e.g. not S-OFF) or your modules don't match the kernel. To figure out what's wrong, first boot the ROM after having installed my kernel. Second, verify that you are running my kernel by running
adb shell cat /proc/version
and seeing that it says crpalmer in (it should match the version that you think you installed, but at least saying crpalmer is a good start). Then do:

(turn on wifi)
adb shell dmesg
and look for an error that says crpalmer in it (something like a module version mismatch error). If you see that, it should tell you the version number of the modules that are installed and the version of the kernel.

That's right. No need to flash the return-to-stock modules either.
Thank you for this! I also find it hilarious that you including instructions for benchmarking. To this day I still wonder why people actually care about benchmarks as they have little to no impact on real world performance.

Self defense... I didn't want to deal with people getting 8K scores and blaming me.
Antutu is actually really useful for testing the thermal driver.
Very nice, does this have the latest changes that were just removed from elkays kernel? Also, could you add the lionheart gov?
Nice to see another kernel to choose from, I will give it a shot this weekend. Will you eventually put any you tweaks? Also, can this be flashed with FlashGui?

I looked at elkays changes and it removes a background task that encourages a USB device to power down. This may or may not be a good thing. I'll see how elkay's testing goes before I pull in the change. If it goes well, I'll give it a try.

What tweaks? It.already has a lot of improvements...
Any idea what flashgui accepts as input?
I didn't see any mention of gpu tweaks so I didn't want to make assumptions, hence my question.
EDIT: I just noticed my autocorrect changed "gpu" to "you" in my post you responded to.

Flashgui worked for me. Renamed file to "boot.img" and ignored the warnings. I like living on the edge. Booted up and shows this kernel version. Thanks for this.
Stay thirsty, my friends
Re: [Kernel] [Linaro] [Linux 3.4.29] Version 1.0.0 - Feb 7
Had a glitch with it already, phone was sleeping, got a message on gtalk and it locked full on vibration, blinking the led, wouldn't wake up and eventually rebooted after maybe 10 seconds. I've had this happen on one of the dsb kernels too, I think. Wiped caches again, hasn't occurred again so far.
Happened not 10 minutes after flashing it so I'm chalking it up to kernel making itself at home, just a note that it happened.
Edit: just rebooted again getting an email notification, UKB 1.3. Seems I can't receive a notification while the phone is sleeping or it jams up and reboots.

After it reboots, can you try to get a log with

Flashed this into PACman, ktoonz kernel never played nice for me. I will report back on my thoughts.
First impressions? Well it boots, strong performance, too early to tell on battery.
Sent from my Galaxy S4
Wake up delay/lag is completely gone for me since flashing this kernel. I'm on the latest CM nightly.
Sent from my SCH-I545 using Tapatalk 4 Beta
So I have been running all day on this kernel. Governor = smartassH3 1998/189 and row scheduler. All set with the native PACman performance settings. No other mods enabled. Not quite the performance I was hoping but not bad considering my slight overclock. Also I have had quite good service today.
Sent from my Galaxy S4
To offer a different perspective, intellidemand, row, 189/1890, no undervolt, CM. Insane so far.
Sent from my SCH-I545 using Tapatalk 4 Beta

Working very well on pac. Too early to tell battery but based on the change log its going to vary on your set up.
Sent from my SCH-I545 using xda premium
I'm enjoying this kernel and can't wait for future updates! So far I'm getting really good battery life with this. I've noticed a couple of issues which I didn't experience when running the KT kernel. I'm not 100% sure it's kernel related, but I never experienced these with KT. 1) Sometimes wifi won't connect and when I try to access wifi settings in the settings menu it freezes and springs a settings is not responding. 2) On occasion I'll get a real system slowdown where I get a bunch of lag. Both of those issues seem to be resolved with just a regular reboot. 3) I use face unlock as my lockscreen and sometimes the camera doesn't work (including after a reboot). So I see like the white "burst" in the box like it usually does when it's opening the camera, but then the camera doesn't initialize and it just shows a black screen.
My settings:
Kernel:
189/1890
Intellidemand
Row
Haven't made any other changes to settings
Rom:
Fitsnugly's (Euroskank) CM10 from 06/07
Otherwise I think this has huge potential to be my go to kernel for battery life.
Albinoman887, just an FYI, flashed the latest kernel build on the 6/12 CM nightly and BT doesn't turn on. Behavior is consistent with what you typically see when a module is missing. Was on the go and couldn't grab a logcat, but will do so if the solution is non-obvious.

Might be some updates to the ramdisk cm made. I'll check it out
Sent from my SGH-M919 using Tapatalk 2
yep looks like its something to do with a CM update. i rolled back to 6/8 and BT works again. they probably changed some permissions or something in the ramdisk. (the lame thing about samsung kernel developing) i'll re-sync the ramdisk code with upstream and see what that does. it should fix it. then i'll release a revised build. until then the June 8 CM build works fine with BT and my kernel, as a temp fix

I have it working now with latest builds let me try and explain it again.
With samsung phones when you flash a kernel you arent JUST flashing the kernel like on HTC. due to limitations in recovery on samsung you have to flash the full boot.img. this img file contains the zImage (kernel) plus a the ramdisk, which is things like init.rc init.cm init.qcom. these are scripts that run at boot to set permissions for radio, wifi, mount points etc.
Since we are limited to flashing the full boot.img these init scripts get flashed during kernel fash as well.
So say you have a kernel build from the 10th. but on the 15th CM changed some paths in the init scripts (which is what they did this time) and you download that update from the 15th, flash it, then the kernel. you lose all the updates to the ramdisk from the 10th on. So if there are some big changes in there it will cause issues like this BT one. usually the ramdisk doesnt get updated much. its just because the device is so new. i predict in a month or so this wont be an issue as all the scripts will be final.
Enjoying some coffee, then i'll post the new build with the updated ramdisk (fixed BT)
Biggest cup of coffee ever! Lol

This kernel extends the CM kernel with some new features:
New init.d scripts to allow some tweaking without needing any 3rd party apps
* See the next post for details.
Replaced HTC's mpdecision with a new custom hot-plug driver that I created:
* This hot-plug driver is more aggressive about bring cores on and off-line to match the load on the system.
* Bringing cores online earlier makes your phone more responsive / smooth.
* Taking cores offline earlier improves battery life.
* It ramps up very quickly on resume to avoid lag.
Replaced HTC's lightsensor table with one that is more sensible and that matches what other devices use. If you have custom auto-brightness settings, you'll probably need to tweak them after installing this kernel.
There are many additional changes to boost performance and battery life:
* Linaro -O3 compiled (Linaro 4.8).
* Overclocking
* I disable tons of HTC debugging crap left enabled and needlessly consuming battery.
* Improvements to the core locking code of the kernel.
* Patches that transform traditional locks into RCU backed data structures.
* CAF changes to power management to sleep faster and waste less CPU during suspend.
* Improved code for moving data to/from user-space and manipulating strings within the kernel.
* And tons of other patches such as scheduler improvements, I/O improvements, networking improvements, etc, etc, etc.
Other features:
* Voltage control (faux123) to allow user-space under-volting.
* BFQ I/O scheduler.
* Track upstream Linux changes

init.d tweaks
I created some scripts that run on boot (init.d) because I install my kernel so many times that I would go insane if I had to use an installer to configure it each time. By using these scripts and configuration files on the sdcard, I can just configure it once and keep installing away to my heart's content.
After installing this kernel, there will be:
/system/etc/init.d/99crpalmer
run at boot, even if you switch to another kernel. It is safe to leave this file there and to let it run as it only makes changes if the kernel contains "crpalmer" in the version. If run with a kernel that contains crpalmer in the version, it will rename mpdecision so it can't run. If you install another kernel it will then rename mpdecision back so that it will run in the new kernel. In addition to stopping the built-in mpdecision it will allow the following tweaks:
CPU Frequencies
* Frequencies loaded from /sdcard/crpalmer-cpufreq-min and /sdcard/crpalmer-cpufreq-max
* Governor loaded from /sdcard/crpalmer-cpufreq-governor
* If you specify either or both of these frequencies, it will lock down all of the CPU frequency controls. I had to do this because HTC overrides them in a script that is run very late in the boot process (thanks HTC!).
* E.g. adb shell su -c "echo 192000 > /sdcard/crpalmer-cpufreq-min"
* E.g. adb shell su -c "echo 1728000 > /sdcard/crpalmer-cpufreq-max"
* E.g. adb shell su -c "echo interactive > /sdcard/crpalmer-cpufreq-governor"
Undervolting
* + or - value loaded from /sdcard/crplamer-uv
* The undervolting in 2.0.23 for FAST binned CPUs would be specified as:
* E.g. adb shell su -c "echo -100 > /sdcard/crpalmer-uv"
Lightsensor
* My light sensor changes didn't sound like they worked well for everyone. If you don't like them you can disable them by:
* E.g. adb shell touch /sdcard/crpalmer-stock-lightsensor
HTC Colour "Enhancement"
* If this file is present then the HTC's colour "enhancement" will be used, otherwise it will be disabled.
* If this file contains the string "m7" then it will use one of the colour enhancement that was used in the M7 kernel for a panel most like ours.
** E.g. adb shell touch /sdcard/crpalmer-color-enhancement

This kernel extends the CM kernel with some new features:
New init.d scripts to allow some tweaking without needing any 3rd party apps
* See the next post for details.
Replaced HTC's mpdecision with a new custom hot-plug driver that I created:
* This hot-plug driver is more aggressive about bring cores on and off-line to match the load on the system.
* Bringing cores online earlier makes your phone more responsive / smooth.
* Taking cores offline earlier improves battery life.
* It ramps up very quickly on resume to avoid lag.
Replaced HTC's lightsensor table with one that is more sensible and that matches what other devices use. If you have custom auto-brightness settings, you'll probably need to tweak them after installing this kernel.
There are many additional changes to boost performance and battery life:
* Linaro -O3 compiled (Linaro 4.8).
* Overclocking
* I disable tons of HTC debugging crap left enabled and needlessly consuming battery.
* Improvements to the core locking code of the kernel.
* Patches that transform traditional locks into RCU backed data structures.
* Different version of ondemand cpufreq governor
* CAF changes to power management to sleep faster and waste less CPU during suspend.
* Improved code for moving data to/from user-space and manipulating strings within the kernel.
* And tons of other patches such as scheduler improvements, I/O improvements, networking improvements, etc, etc, etc.
Other features:
* Voltage control (faux123) to allow user-space under-volting.
* BFQ I/O scheduler.
* Track upstream Linux changes

How do i run the scripts?
I didn't like smartmax anyway...made me feel like I had a droid incredible again. Very VERY smooth. This on crdroid with halo 2.0 is gold. Thanks for sticking with us. Fast charge would be nice, but I'm content.
Do you take donations? Not trying to look haughty or anything...I truly don't know.

Actually smartmax is gone from anything using the CM kernel, not just my kernel. I think crdroid is using their own kernel so it may still be left in there (it's up to them whether or not they cherry-pick my removal of it...).
I don't accept donations. I do all my android work for fun and only for fun. Thanks for the thought though.

Just wondering crpalmer, when you release new kernels like this, do they also contain all of the previous optimizations and such as the kernels before, like an update to work with the new android OS?

See post #2, it contains example adb commands.
Chris, what are your thoughts regarding the performance options in CM where you can allow purging of assets and kernel same page merging?
I used to have those enabled but I turned them off a couple weeks ago and noticed no difference.

The scripts get run every time you boot the phone. Post #2 explains how you configure what the scripts do. There is nothing that you need to run yourself.

No need to use unless you have little to no AFM (absolute free memory). On phones with less than a gig of ram, KSM is pretty much a given need, as it will merge identical bytes to free up more ram. I have never had less than 600mb AFM on this phone to need to turn on KSM.

Q: What is QV version?
A: QV means "qualcomm voltages". qualcomm made a patch and stuck all voltages to 1150mv to improve stability. QV version has got all 1150 mv for each freq (like older 3.4 kernels).Q: I plugged in my pen drive but i can't found it
A: look in /mnt/usbdisk folder.Q: What's and how i enable/disable fastcharge?
A: with fast charge an USB charger will recognized as AC charger. it won't charge your phone faster with an AC charger. it may not charge your phone faster with an USB charger.
with the usb cable UNPLUGGED edit /sys/kernel/fast_charge/force_fast_charge:
0 -> disable
1 -> enable
than plug in the cableQ: i've got random reboots, what do you need?
A: first read here
write this info:

Q: what's BLN and how i enable/disable it?
with BLN on when you received a notify the soft key will blink.
to enable/disable edit /sys/class/leds/button-backlight/blink_buttons:
0 -> disable
1 -> enableQ: what's s2w and how i enable/disable it?
Sweep2wake allows you to wake up your device by swiping your finger across the capacitive buttons from left to right. Swiping from right to left will put it back to sleep (sweep2sleep).
to enable/disable edit /sys/android_touch/sweep2wake:
0 -> disable
1 -> enableQ: what's dt2w and how i enable/disable it?
DoubleTap2Wake (DT2W) allows you to wake the device by double tapping the capacitive buttons.
to enable/disable edit /sys/android_touch/doubletap2wake:
0 -> disable
1 -> enableWhat's sleepy_plug and how can i activate/deactivate it?
sleepy plug it's an hotplug driver (it decide when turn on the second core) i wrote. it's an experimental driver and it may have got performance problem. if you notice some decrease in performance report it.
to enable/disable edit /sys/module/sleepy_plug/parameters/sleepy_plug_active:
0 -> disable
1 -> enableInstall instruction:S-OFF:
- flash the zip in recovery
- wipe caches (optional)S-ON:

Ok....update.
I flashed today's build (QV version), and here are the changes.
- The different governors now show up.
- Sweep/Doubletap options don't show up in TricksterMOD.
- I tried to force sweep2wake to work through Kernel Tuner, but the phone froze after I applied the new settings.
- I didn't notice your post soon enough to try the interactive governor. I will post an update soon.

duki994 Kernel for Stock TouchWiz LP ROMs
A personal project that had good results and I wanted to share it with others
It's based on official Samsung sources for Lollipop firmware.
Important note:
This kernel should work on any custom ROM that is stock lollipop based
Features:
* Wolfson Audio control (thanks to @AndreiLux)
* Battery charging control (thanks to @AndreiLux)
* CPU voltage control for both A7 and A15 cluster (thanks to @AndreiLux)
* Exposed all OPP voltage controls (thanks to @AndreiLux)
* Powersuspend v1.7 by @faux123 and @Yank555
* LMK, MM and FS powersuspend mods ported from @dorimanx's LG G2 kernel
* SCHED code fixes
* SCHED: HMP thresholds changed and new patches implemented
* Many changes related to ARM instruction code and lowlevel ARM core management
* Enabled NEON mode in kernel with full VFPV4 support
* Added new SHA256 and SHA512 NEON accelerated algortihms - now blazing fast
* UKSM (Ultra Kernel Samepage Merging) - algorithm that's better optimized than standard KSM
* WiFi standby wakelocks (PNO wakelock) reduced
* WiFi userspace power mode/DTIM change (for advanced users ONLY)
* WiFi driver switched from deprecated earlysuspend to use newer powersuspend driver (this is to fix some of bugs that could lead device kernel crash)
* NET updates
* Enabled all TCP congestion protocols and set Westwood as default (best wireless performance)
* Disabled KNOX
* SELinux disabled in kernel
* Fully configurable in Synapse (download from Google Play)
/* Important note to other devs */
You cannot include this to your ROMs. I can't be responsible if anything goes wrong, I can't help with any issues without knowing kernel version and users should be routed to this thread if they want this kernel, or if you recommend it. I think that it's best to separately view custom ROM and custom Kernel, so each dev (ROM or Kernel one) can work on bugs/features and make it as compatible as it can.
However, you can add this thread link and mention me in your thread, so people would know where to ask if some kernel problem arises
Warranty void
By flashing this kernel you will void your warranty. I'm not responsible if you brick your device, or if someone starts nuclear war.
Note:
Don't change voltages on "Busses" tab if you don't know what you are doing. It can reboot your phone if your memory controllers, ISP or MMC controllers can't handle low voltage.
WiFi pasword resetting fix:
Code:
1. open your build.prop file
2. find line ro.securestorage.support
3. change it from true to false (if not already false)
This line being on true will make your WiFi not work good with this kernel. This is due to Samsung's rooting restriction and other Samsung specific workarounds to stop rooting and flashing. Any custom ROM probably has this line changed to false.

*Fully updated ROW I/O sched added (experimental)
Version 1.2
* Synapse:
-> disabled min cpu freq control. not needed.
-> added new I/O schedulers
* Massive updates to BLOCK, SHCED, MM, WORKQUEUE critical code
* Added FIOPS and BFQ I/O schedulers
* EXT4 updates to fix possible kernel crashes
* ZSWAP now uses ultra fast and light on cpu LZ4 compression
* CPUFREQ optimizations
* Updated BFQ, FIOPS, DEALINE scheds with fixes and optimizations
Version 1.1
*Synapse:
* Added live cpu stats for all 8 cores (quad A7 and quad A15 cores)
* Added live CPU temperature monitoring
* Added live battery temperature and health status
* Disabled broken battery input current feature (shows 0mA for our PMIC chip)
* Added misc tab:
+ ability to take logcat,dmesg,last_kmsg
+ HMP Little packing switch ON/OFF and explanation
* Added optimized ARM RWSEM algorithm
* Fixed HMP so HMP little packing would work good with our implementation
* thermal IPA(Intelligent Power Aware) now updates power tables immediately when voltage changed from Synapse
* entropy depletion fixes
* Enabled FRANDOM random number generator module for more entropy and less lag
* Added NEON instruction accelerated SHA256/SHA224 algorithm. Now we have SHA384/SHA512, SHA256/SHA224 and SHA1 algorithms NEON accelerated - blazing fast
* HMP little packing switch for Synapse
Experimental option made by nvidia. It groups tasks so more of them would be scheduled across power saving cores (A7 cores in our CPU). It may or may not save battery depending on your usage.

How to build this kernel guide
PREREQUISITES
What you need installed to compile
gcc, gpp, cpp, c++, g++, lzma, lzop, ia32-libs flex
If on 64bit Linux, install gcc multilib
Project folder structure
--project_root/ #### can have any name
-----ramdisk_source/ ## defined by RAMDISK_TMP var in script
-----ramdisk_tmp/ ## defined by RAMDISK_DIR var in script
-----kernel_source/ #### can have any name
-----RELEASE/
TOOLCHAIN INFO
Toolchain is already into kernel dir. You just need to have
correct folder structure and run this script. Everything will be auto-built
FLASHABLE ZIP
Flashable zip will be located in project_root/RELEASE directory
and will have name Kernel-slte.zip
All other explanations here:
https://github.com/duki994/SM-G850_Kernel_LP/blob/master/build_kernel.sh
Clone ramdisk source in ramdisk_source
Clone kernel in kernel_source folder
Be sure to have project directory structure as written above
After that, you just need to run:
sudo bash build_kernel.sh
in kernel folder. And voila. After finished you have Kernel-slte.zip in RELEASE directory
If it show any errors, open kernel source and type in terminal:
chmod -R 755 *
Then repeat sudo bash build_kernel.sh
awesome job, thank you
finally undervolt .. yay

I reduce voltage A15,A7 (every speed) by roughly 20mv
gaming (coc,asphalt,etc) for roughly 1 hour; result=stable :good:
edit: volume in the audio also work, louder headphone.
Thanks, I'll try it.
how the battery with this kernel?

Battery? It's better than stock for me. For screen on, this morning I had 50mins SOT and 87% battery left. That's even better than my LG G2, which is a beast according to tests
My father uses Galaxy Alpha, and yesterday he managed to get 4h SOT with HSDPA data on.
When screen off (in suspended mode) it's very low power consumption due to Powersuspend driver. It's better than stock.

I have no access to G850L model. I don't know if it will work.
During this week, if I have enough time, I'll download G850L source and build it with all mods/features and give you to test it
thanks duki994.
which app I need install to control on the kernel?
hi!
1. how do You undervolt by 20mv, in synapse i have steps like 1x,xxMv and can set up -25Mv??
2. I have strange warning message after installed this kernel. it says phone needs to reboot. after reboot the same. just annoying

1. Our voltage regulator accepts 6.25mV step. So you can UV/OV in multiples of 6.25. When you do math, 6.25mV x 4 = 25mV
You can't UV -20mV. You can UV -18.75m (3 x 6.25mV). Next step is -25mV (4 x 6.25mv).

No UV. All stock. Only changed earpiece volume (incall speaker volume) to higher (+4dB if I recall good from this morning). It's for better hearing incall
UV generally doesn't reduce battery consumption (it's maybe 1%-3% less power usage). Real benefit of UV is lower CPU heat and prolonged life of motherboard.
Some chips can't handle UV at all. Some can be UV by as much as -150mV. It all depends on specific chip that came out of fabric process. Note that UV brings instability on some devices.

On which ROM are you? Everything works for me on stock. I have to see if anything changes it.
Did you set secure storage to false in build prop?
I'l automate that in next build.
Kernel doesn't mess with options like recent buttons and Java written parts of Android OS.

Please read OP before asking. Everything is said there.
Synapse is the app with which you can change settings of this kernel.

I am on ozcan rom 4.1. my recent button only works with Nordic based stock which is NEE G850FXXU2COI3 5.0.2 11.09.2015 5614954 and ozcan rom..and with any other rom like rr and cm12.1 my recent button does not work.. secure storage is false by default on build.prop .
