* Sorry for the long delay. Got burnt out on android for awhile and got some new toys as well so was busy
* All the needed updates to kernel and Ramdisk since last release and to comply with CM"s new all-in-one rom build,
because of this we can now use one flashable zip for all qualcomm variants now. I added the auto-loki patching from
CM's rom zips so loki should be done for you. let me know if you have any issues.
* Updated kernel to 3.4.82
* I'm sure there are a few small fixes I forgot since last release but basically you can expect what you did with the last release just up to date.

* Please keep all comments in this Discussion Thread. Any comments not in that thread will be ignored. Feel free to use the DevDB Bug reporting option as you see fit. This is critical in keeping the same question from being asked times in 5 different threads all with the same answer. It was really slowing down development.
* ]If you have problems with frequencies sticking use "No frills CPU Control" and go to Settings and prevent other apps from changing CPU settings
* Although this kernel has now reached "stable" status. bugs still could pop up. please if you find a reproducible bug and decide to post please try and provide a last_kmesg or logcat.
* Versions go as follows: AOSP-JB4.3 = CM-10.2 etc, AOSP-JB4.2 = CM-10.1 etc, TW-JB4.2 = Android 4.2 TW based ROMs, TW-JB4.3: Android 4.3/Google Edition based ROMs

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
might have to try this out
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.
Sent from my SCH-I545 using Tapatalk 4 Beta
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
someone have the older kernel from the 8th

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

lol sorry. got busy with life, and had to reinstall my os for various reasons. back in business now
No complaints, just seemed like a good joke

Just wondering is anybody knows oz this kernel had CIFS support.

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.

* 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!).
* CAF updates to lowmemorykiller.
* Reapply elkay's HSIC fixes by pulling the real commits from CAF (instead of his hand copied commits) which fixes two problems in his commits.
1.2.2: April 1, 2013: linux 3.4.38, lag fixes, bluetooth drivers, cleanup:
* Undo some dubious commits (or extra code included in unrelated commits, what I meant by "early mistakes"). I reexamined every commit in the kernel to decide whether to keep it or remove it.
* 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 3.4.36
* Small bug fixes from CAF
1.0.18: Mar 7, 2013: Linux 3.4.35
* Linux 3.4.35
1.0.17: Mar 4, 2013: Linux 3.4.34, Linaro 4.7-2013.02, thermald fix
* 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).
* msm_thermal: react better when temperature decreases.
* simple_plug: be slightly less aggressive about bringing cores online.
* New suspend mode PM_SUSPEND_FREEZE
* Oprimization for RWSEM lock handoffs.
* RCU locking in cpufreq!
* Disable more HTC debugging code.
1.0.11: Feb 22, 2013: Battery optimizations, Linaro 4.8 build, update.zip format
* Disable HTC's PNP power manager and adaptive policy services (used for thermald / mpdecision which are already disabled).
* 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.
1.0.0
* Merge linux 3.4.29
* simple_plug: a new CPU hot-plug driver (default)
* msm_thermal: a new thermal throttling driver (default)
* faux123's intelli_plug (disabled by default)

FAQ
sweep2wake: I have no plans to add that to this kernel at this time.
FAQs
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.
** 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.

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
adb shell cat /proc/last_kmsg > last_kmsg.txt
and send a link to the last_kmsg.txt file?

Ah, that makes more sense... I'm planning on including dsb's changes to any overclocking, etc. but I don't have the knowledge to tweak these settings myself.

My Github (main): https://github.com/Team-Hydra/android_kernel_samsung_jf
* First off of course cyanogen, the CyanogenMod project and all who contribute.
* A lot of this was taken/based off of flar2's Kernel for the HTC One, so thanks for the source!
* Also grabbed some things from Faux123's kernel
* All the people who have helped me learn more and more over the past 4 months (arco/dastin1018/android1234567) you guys are the best!
I really didn't want to do this but people keep asking so here is a donation link if you want to buy me a coffee or pack of smokes (I go through a lot sitting on the PC messing around lol) go ahead. But not required or expected by any means
Note: The name on the paypal account may say patricia, this is because it's a family paypal account.
Happy Flashing

lol guys just try the kernel....its really stable. ive had it on all the other variants for about 2 months i just forgot about sprint lol. its loosely based off of Ktoonsez's kernel. (we trade fixes back and forth) bot mainly based off of CM with all the additions mentioned plus a few more little ones like frandom support i think its the only kernel with L2 cache overclocked though, which gives a nice boost i think. and battery life is great, and no reboots or anything i'm aware of

Do u plan to cook up a TW kernel or just AOSP/CM??
eh maybe...never messed with TW i flashed CM right when i got my phone so not sure
Been running this since last night. So far so good. Haven't changed any settings because I usually use intellidemand. Are there any settings you suggest changing?

anyone test the TW kernel?
and to set GPU clock open /system/etc/chronic-config.sh and look for the GPU section. it has a list of values you can pick from. then just save and reboot

the upcoming release will feature backports from caf and linux and a rewritten anykernel, but i'll look for dt2w for sure.
New update out!
AnyKernel2 is rewritten, now removes scheduler/readahead overrides present in cm ramdisk.
Kernel is updated with backports and other stuff.
I've added logger control via sysfs:
path: sys/module/logger/parameters/log_mode
// 0: Enabled, 2isabled
Flash and enjoy.
Last KK update
Hi folks, here is my last kk update.
I've rebased the kernel on slimkat-kernel, and added my optimisations on top of it.
I've removed over 40k lines of unused deprecated code!
It will run best with slim.
See here for the changes i made.

Well, this is simple to answer.
I won't include any other than the already included governors.
For a fact all these govs like lionheart, etc.. were designed years ago and deliver subpar performance compared to the included governors, as they are designed with old single or dualcore devices in mind ( and pegasusq uses its own hotplug logic).
Only difference are faux intelli governors which are quite actual codewise, and a few more others which are optimized for modern devices.
But the best performance and battery life will be achieved using a frequently updated interactive or ondemand governor.
@madsponge26
i'm working on bringing dt2w.
I'll see if i can fix a few things such as >2taps mostly and implement a wakeout time like flar2.
It's already working quite good, thanks @blueether for the base.
I can't do much on lollipop as my knowledge is very limited and c only, so i'll let the others who have more knowledge doing their job and supporting them if it's in my range.

wait are you saying not to flash what is uploaded? I know CM12 defaults to encryption, doesn't bother me im encrypted already.

Came in to see the same - guessing from the question going unanswered that there is no sensor_ind fix in this kernel, at least as of now. I'm really, really hoping 5.1 fixes that horrible wakelock.
Sweet.ran your kernel on my nexus 5

Bothers the rest of us buddy, who do not wanna be encrypted in case we decide to try the kernel. You can always decide to encrypt yourself, no need to be forced to do so.
Awhh snap. He's here . woot !!

Synapse gives me the No UCI Error on boot and it persists until I clear app cache. On Dirty Unicorns and latest nightly with set on boot applied - if you need dmesg/kmesg/logcat let me know which.

Criterion is a highly customizable fork of @z3DD3r's LineageOS kernel. It features various popular cpu governors, hotplugs, I/O schedulers, kcal color control, doubletap2wake, sweep2wake etc and is built with Linaro GCC 7.5.0 (O3 and hard-float optimizations enabled). Make sure the latest version of Magisk is installed.

The kernel works completely fine on LOS 17.1. But I couldn't find time to try it on other Android 10 based ROMs. This is a pre-release for anyone interested in testing the kernel. Give it a shot and share your experience.

Congratulations, you have done such a wonderful incredible job :good: :victory:.
If you don’t mind, could you please sent the final file "FKE_v2.1.0.zip" to me ? I am trying to install Magisk v20.3, but the attached file "FKE_v2.0.0.zip" does not work pretty well. It's just useful for my phone within Pie rom. Thanks so much :highfive:
