/* Switch to f2fs */
As mentioned above, this kernel fully supports f2fs.
However, you are completely free to choose not to use f2fs.
You can selectively convert partitions to f2fs using TWRP provided in the downloads.
You should use the provided TWRP at all times after you switched to f2fs.
/* Disclaimer */
Your warranty is now void.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this kernel
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

Initial release
/* Customizing kernel */
You can install Synapse from the Play store to control voltage and other frequencies.
To control some core kernel parameters, create /sdcard/arter97 as a directory and do the followings
--- Enable Adaptive LMK ---
Enabling Adaptive LMK will increase responsiveness at the cost of reduced multitasking capabilities and battery life.
Create a text file with 1 letter "0" under /sdcard/arter97 named "adaptive_lmk" and reboot
--- Disable LED fade ---
If you have issues with other 3rd-party LED controlling apps, try disabling it.
Create a text file with 1 letter "0" under /sdcard/arter97 named "fade_led" and reboot
/* To kang or not to kang */
I prefer "open" to all stuffs, explicitly except for my personal kernels.
I've once used to use private Git repository for my kernels and just release the source-codes as a tarball,
which means that other developers who are interested in my kernel's changes would not get the specific changes they want while not violating XDA forum rules or GPL.
That was almost 3 years ago which by then, I was a newbie developer on XDA.
I was afraid other big developers merging all of my changes and I'll get buried down.
However, I've changed my mind and opened up my Git access to everyone after thinking my previous actions did not belongs to XDA's spirit.
That was a big move for myself of re-thinking what should be open.
Later down on the road as I gained more development skills, I've contributed into CyanogenMod and other's custom kernel and ROMs for fixing stuffs, introducing new concepts or improving performance.
During such process, there were quite a lot of occurrences where I was actually the first one to do those things.
For those who're familiar with "temasek ROM", you may know that after I became a contributor, temasek rose even more into the center of other AOSP ROMs' attention, as I was the first to introduce new exciting stuffs such as compiler changes or f2fs. And I quickly gained dozens of followers on my GitHub account.
And eventually, people *kang*ed my changes. Sometimes invalidating my authorship.
It surely is not a right thing to do, but I let it slide as it didn't matter that much. I believed that if my changes are good enough, it'd be better to end up with a larger user base rather than being a **** trying to hunt down every ROM developers who're doing it wrong.
Same story goes to my ROMs.
My real first popular ROM was back-to-n00t, which is a ported ROM from Galaxy S3 LTE to provide stable Touchwiz KitKat experience to the Galaxy S3 3G users.
I opened up everything to GitHub. And I even encouraged that other ROM developers to use my ROM as a base to work on their own ROM as I knew there are a lot of Touchwiz ROM cookers who're way better than me on modifying SystemUI or frameworks(via smali) BUT aren't too good on porting ROMs. I hoped that my ports can be a great base for others to work on their own modifications.
Now those spirits repeated on the Galaxy S6, I opened up everything about back-to-n0t3.
However, I do not do or believe those same things with the kernels.
There are far less kernel developers on XDA compared to ROM developers. ROMs are much more appealing for an "Android newbie" to go tweak. You can modify UI, enable some hidden settings and even port features from another devices.
So when ROMs gets copied off, users can easily distinguish if that was stolen or not.
Let’s say a well-known developer A ported S6 designs and features to the S4. Next day, less-known developer B uploads a ROM on XDA that claims to do the same thing. First thing that comes to the users’ mind would be ‘Is that guy a thief?’.
However, same thing cannot be said on the kernels as they work on a much lower level. You can’t distinguish individual custom kernels just by staring at your phone.
If a ROM developer choose to go use other’s custom kernel and integrate it into their ROM, it’s most likely that users won’t appreciate that custom kernel developer whose work powers that ROM. Let’s face it, not all users care about “Thanks to”, “Credits” sections, and let me tell you, those are the majority. Now some custom kernel developers might be OK with that. However, I’m not. Unlike most developers on XDA, I got fascinated to Android because it runs on Linux kernel. Modifying Linux kernel was the first thing I’ve done on my Android device, not modifying ROM. And I spent years and years on gaining information on Linux/Android kernels and tweaking, coding myself. While I don’t necessarily care users choosing to NOT use my kernel, I cannot stand that my kernel would be installed on one’s device which its owner don’t even know which kernel, which developer who made that kernel is. That is why I’m against with the idea of integrating custom kernels into custom ROMs. If you want your users to have a custom kernel, let them learn themselves what that kernel really is, what does it offers, and who developed it. “For the ease of flashing/installation” is not an excuse for me. Take yourself a few more minutes to download a kernel from the web, and a few more seconds to flash a secondary ZIP file from the recovery. Is that hard? Time-consuming? Absolutely not.
I hope everyone gets the idea why I'm sticking with the idea of "don't integrate my kernel into others".
Cheers.

Stuff like this makes me want to root! -_-
Ohhhhhuuuu yes!!!! DT2W ohhhuuuuuuu yes!!!!!
No download link hmmm not working with twrp?
Is it for 5.0.2 or 5.1.1 or both firmware?....can i flash using twrp on my s6 g920f?...TQ
Awesome
Just installed on XtreStoLite DeoModEdition 2.1 and the first thing I noticed was how much faster my s6 boooted up, oh my! Thank you so much! Double Tap 2 Wake doesn't seem to be working for me, any suggestions?
tried to flash recovery on g925f and once its flashed and you try to boot into recovery the screen just flashes and then stays black.

CHANGELOGS IN #2 POST
You can tweak multiple options of this kernel with TricksterMod, FauxClock, Kernel Adiutor, Synapse(r500 and up, definitely recommended to get the most available options) or similar apps. (They are all available on the PlayStore)
Note to MultiROM users : don't use the kernel sharing feature. Flash the kernel on each rom instead. Also, it may take more time booting on secondary roms when using F2FS. Don't worry and wait for a bit

FAQ :
What are the differences between "Full" and "Pure" builds ?
The "Full" builds are using Aroma Installer so you can tweak various options at flash time. At the end of the process, a file containing your settings will be created (/sdcard/glitch-settings.conf). The "full" builds are also able to restore your settings from Aroma after a rom flash or wipe for example.
On the other hand, "Pure" builds aren't coming with Aroma and will try to restore your settings from your SDcard, or use a default profile if none is found. Both Full and Pure builds are coming with a custom Synapse support to let you tweak all the core options on the fly once booted.
If you flash a "Pure" build without a profile, the default preset will be applied. It's been tweaked for a good balance between performance, power consumption, stability and functionality for day to day usage. The default settings applied are as follow :
- 1.7GHz max CPU freq (from 1.5GHz stock) / 1GHz max CPU freq when the screen is off / "Balanced" L2 OC
- msm_hotplug driver in place of msm_mpdecision
- 450MHz max GPU freq (inline with other Snapdragon 600 devices - from 400MHz stock)
- Safe CPU and GPU undervolting for lower heat and power consumption
- Deadline I/O sched / Interactive CPU governor
- Doubletap to wake and fastcharge enabled (Doubletap to wake will slowly drain power during suspend, so disable it if not used)
- Everything else is kept stock
What do I have to do to use F2FS on one (or more) of my partitions ?
First, BACKUP your data if needed, especially if you're planning to use F2FS on DATA partition, as changing filesystem will wipe the partition. Change partition formats as needed in your recovery. It is NOT recommended to convert system partition as F2FS as it'll be slower than EXT4 to begin with (as the partition is mostly read only) and will alter compatibility with many roms (especially CM/LineageOS based). The last thing to do is to flash any Glitch kernel with a revision number past r150. You can restore your settings from SDcard if any, the install process will detect the partitions and modify the ramdisk accordingly so you can finally boot and use your fresh FS.
What L2/cache OC setting should I use ?
This setting will overclock bus speed and RAM so it's a bit delicate to tweak, yet it can give a nice "free" global performance boost. A simple test to check for stability is to run the camera app 3 or 4 times in a row while waiting for 10 seconds between each launch. If your device freezes, it's unstable ! It's also the only setting you can't change on the fly once booted, either from Synapse or sysfs, and requiring a reflash (using Aroma or changing the value in /sdcard/glitch-settings.conf).
Let me give you some details about the available settings so you can choose wisely :
Stock (1.13GHz-4.26GBps) is the regular, out of the box, non OC setting.
Improved (1.19GHz-4.26GBps) is the same as "ElementalX" setting in Flar2's kernel.
Balanced (1.22GHz-4.66GBps) is the same as "Ultra" setting in Flar2's kernel.
Fast (1.35GHz-4.66GBps) is a nice jump over "Balanced", yet stable for most devices. A kind of sweet spot.
Extreme (1.43GHz-4.80GBps) is were most users will start to get issues. Provides a great boost if stable.
Glitchy (1.49GHz-4.80GBps) pushes your hardware to the limits. Will be unstable for most devices.
Thanks to everyone helping me to debug and find new useful things to integrate !
Without all of you, this kernel wouldn't be !

Latest release's changelog with words for humans :
14/09/2017 - r574 :
- Synced with latest LineageOS 14.1;
- Updated toolchain to Linaro GCC 7.1.1-2017.08;
- Added touchscreen-calibration fix patch by parrotgeek1;
Previous changes below :
17/07/2017 - r572 :
- Synced with latest LineageOS 14.1;
11/07/2017 - r571 :
- Synced with latest LineageOS 14.1;
29/06/2017 - r570 :
- Synced with latest LineageOS 14.1;
- Updated toolchain to Linaro GCC 7.1.1-2017.05.
03/06/2017 - r566 :
- Synced with latest LineageOS 14.1;
- Changed the behaviour of the permissive/not permissive switch to either force permissive or keep rom default (instead of forcing enforcing before) to prevent issues with some implementations;
- Added a service that restarts GMS (Google Mobile Services) post boot to fix memory leak/battery drain linked to them - Curently working in permissive mode only (like init.d and some advanced Synapse settings);
- Updated toolchain to Linaro GCC 6.3.1-2017.05.
07/05/2017 - r565 :
- Synced with latest LineageOS 14.1;
- Added a simple check for the MPDecision service starting mechanism used by your rom : If it's using the same trigger as LineageOS (init.flo.power.rc), you'll be able to enable/disable the service at will after boot. If it's using a different trigger, the binary will be nuked the old way (renamed to mpdecision_bck) if you're using the in-kernel msm_hotplug driver (effectively preventing you to play with it after boot). It's not a solution that pleases me, but it will fix cases of both hotplug drivers loaded at the same time on non-LOS-based roms, and that's all that counts for now.
14/04/2017 - r564 :
- Synced with latest LineageOS 14.1;
- Corrected HZ reference in touchscreen driver.
30/03/2017 - r563 :
- Fix potential touchscreen inconsistencies on some panel revisions
- Fix gesture switch (S2S/S2W/timeout)
27/03/2017 - r561 :
- Synced with latest LineageOS 14.1;
- Backported high-resolution support for sched-clock;
- Fixed CPU detection on subsystem_restart;
- Make rpm clocks sleeping clocks;
- Pushed updates from franco kernel regarding GPU, CPU freq and video;
- Added Zen I/O scheduler (pretty nice sched to say the least);
- Enabled I/O is busy flag for msm_hotplug driver by default (boosts CPU freq during heavy I/O load -> big smoothness gains in many apps and games);
- Added compiler fixes and optimizations from alesaiko (breakfast kernel);
- Moved to latest Linaro GCC 6.3.1 compiler (as the changes above fixed high power consumption issues on GCC5+);
- Consolidated Synapse support. The path of the generated config file is now /data/synapse instead of ramdisk to keep it safe during rom upgrades and reboots. If you get a "No UCI support" message on first Synapse launch, just kill the app and relaunch it. It'll not happen again after that unless you wipe data or I'm forcing a regen in a future update.
- Fixed init.d injection not using the correct path for busybox since a few releases and updated the execution process to N standards;
- Changed the way we get rid of mpdecision to prevent the service from starting in the init process instead of renaming the binary. This enables the possibility to enable or disable mpdecision on the fly after boot, even if using msm_hotplug as default hotplug driver.
- Fixed missing options in Synapse;
- Added various smaller performance patches and optimizations as well as a few more variables to play with for nerdz and lolcats (see github commits);
- Tweaked debugging config;
12/03/2017 - r544 :
- Sync with latest LineageOS 14.1
- Disabled backlight dimmer by default - Added a note to Aroma installer about potential issues with some panel revisions
23/12/2016 - r543 :
- Sync with latest CM14.1
18/12/2016 - r542 :
- Enable RPFILTER (CM14.1 tethering fix)
05/12/2016 - r541 :
- SElinux switch now works on boot without needing root access. As a result, also removed related post-boot script hooks
- Added prebuilt config file for Synapse for faster launch and fix possible error on first launch (clear Synapse data if you get issues)
04/12/2016 - r540 :
Due to some of the changes in this build, restoring settings from sdcard backup (by flashing Pure Edition or restoring through Aroma) may lead to different settings being applied depending on what you set before. It is strongly suggested to use the Full installation at least once to update your settings or delete glitch-settings.conf on the root of your sdcard before flash to use the default preset.
- Post CM14.1 merge cleanup pass. It was definitely needed ! Including, but not limited to :
- Removed Lazyplug and Intelliplug hotplug drivers (due to conflicts leading to performance issues)
- Removed Dynamic Fsync / Added switch to disable Fsync (after corrupting ~15 installations with DynFsync, I don't feel like it's worth the slight I/O perf boost)
- Replaced Showp1984's DT2W by flar2's S2W/S2S/DT2W (the touchscreen issues I faced with it aren't reproducible anymore)
- Removed LZ4 and use XZ compression instead
- Removed WQ_POWER_EFFICIENT (couldn't see a measurable gain with it enabled)
- Removed ROW ioshed
- Rollback'd to older Intellidemand governor- Reworked settings application and restoration system to work with CM14.1/without SuperSU and load it early during boot by init hooking (CM14.1 PCC livedisplay related race condition "fix" included). Note : MultiROM users, you may want to disable MultiROM menu if you have it enabled to further reduce the chances to trigger the issue (completely fixed it on my side). Feel free to report your findings on the matter.
- Added flar2's ElementalX governor
- Updated default profile (the one you get while flashing Pure package or using restoration option in Aroma without sdcard backup)
- Updated thermal profiles
- Updated available options in Aroma
- Updated busybox to 1.25.1 YDS and moved from /sbin to the more convenient and standard /system/xbin
- Updated Selinux switches to work with more roms (now working on CM14.1)
- Moved Synapse files from /data/synapse to /res/synapse in ramdisk
- Updated Synapse presets
- Updated Synapse settings (Aroma installer will give more gestures-related options though, at least for now)
29/11/2016 - r534 :
This kernel will only work with AOSP 7.x and latest CyanogenMod 14.1 based roms. If you get incorrect colors and slow UI, rollback to r533 CM.
- Rebased using CM14.1 tree
- Updated color controls to mimic CM's PCC implementation (Thanks @flar2)
07/11/2016 - r533 :
- Added SDCardFS support
- Fix for CVE-2016-3903
- Fix for CVE-2016-3934
- Fix for CVE-2016-7117
- Added LazyPlug switch and settings to Synapse (hotplug tab)
- Added DT2W switch to Synapse (misc tab)
- Fix GPU voltage range formatting in Synapse
- Fixes regarding power efficiency
- Contextual fixes and speedups
- Now building CM variant of the Nougat kernel too. AICP is the first N rom on this device to require a CM compatible kernel.
14/09/2016 - r530 :
- Modified rom injection/flash time mods logic to be more robust and universal. Fixes inconsistent boot or even bootlooping on hybrid F2FS roms like CyanogenMod or PureNexus THIS CHANGE MAY FORCE YOU TO REFLASH YOUR ROM TO BE ABLE TO BOOT (even on a non-hybrid rom - no wipe required)
- Fixed settings not applying after setting them through Aroma/glitch-settings.conf
- Security patch to avoid invalid access to ashmem area
- Security patch for vulnerability CVE-2016-2059
- Removed deprecated binary injection code
- Default thermal presets calibrated for better efficiency and performance (they were too aggressive in r520)
- Little naming change for the builds. Full is still "Full", but "Restore" is now "Pure". Pure edition is now fully standalone and doesn't require a previously generated profile from Full edition (but will gladly restore it as before if found during install). It can be fully tweaked through config file and/or Synapse like Full edition.
- Nougat build "Full edition" now has a Nougat themed splash screen for Aroma
- Synapse presets are now working. Make sure to press apply when Synapse comes back if you want to keep it ! (Make sure to clear Synapse data after first boot to force a regeneration !)
- Small things you won't notice
24/08/2016 - r520 :
- Rebase from latest AOSP sources
- Synapse support with many more features and personnalization available than ever before ! Aroma settings are a joke compared to what you'll have in Synapse. Don't flash UKM on top by the way, and make sure to clear Synapse data if you've flashed one of the previews. Even more to come soon.
- Updated Neobuddy89's msm_limiter driver to latest from Nexus 6
- Updated Neobuddy89's state_notifier driver to latest from Nexus 6
- Moved to Faux123's Intelli-thermal driver
- Added some memutils optimizations and more for performance
- Updated Xbox One gamepad driver
- Removed loads of dead code and buggy merges
- Switched to Linaro 4.9.4 toolchain - After weeks of testing, my tab runs cooler, stabler, and longer than with 5.x for an invisible performance difference. Worth it !
10/08/2016 - Preview r516 is available here. More options available in Synapse which is now also enabled with the "full" build, merged android-6.0.1_r0.105, and various other tweaks for speed and power savings. Full changelog here.
04/08/2016 - A preview (r513) is available here. Synapse part still needs some work. Notably, some hotplug drivers options are missing and you can't apply presets. The kernel itself should be stable enough for day to day usage.
12/07/2016 - r499 :
- Fix for glitch settings not applying if the rom doesn't use the init.trace.rc file (Dirty Unicorns is one of them)
- Sync fstab with latest cm13 (may fix usb otg on cm13 based roms in some specific configurations)
11/07/2016 - r478 r498 :
- Synced source up to android-6.0.1_r0.98 changes (latest)
- Getting ready for rebase and Synapse-compatible release
- Removed deprecated libs from r478 installer (fixes setperm errors on some custom/recent roms)
- Fixed CM compatibility
10/12/2015 - r412 :
- Merged with android-6.0.1_r0.1 changes
- PowerHAL patch to fully disable touchboost calls when Qualcomm MPdecision isn't used. This gets rid of the touchboost log spam and (small) overhead.
- Updated F2FS
- Installer scripts fixes and cleanups
- Added back CM build - untested
02/12/2015 - r410 :
- Updated base to linux 3.4.110
- Merged with android-6.0.0_r0.1 changes
- Added Neobuddy89's MSM Limiter driver, enabling max/min/suspend frequencies tweaking on the fly. No more need to reflash for that (/sys/kernel/msm_limiter/ for who's interested). Also added his state notifier driver for further tweaking.
- Removed MSM Sleeper as it's covered by MSM Limiter already
- Changed how settings are applied (moved from init.d script to service) to prevent permission denied issues (Thx Flar2). Due to changes to the way your settings are handled, it's recommended to make a full installation. Settings aren't retrocompatible with previous Glitch kernels !
- Performance and stability improvements by removing coresight from Adreno drivers and better CPU management/scaling through MSM Limiter
- Aroma slight changes to reflect internal changes (note : CPU uV is now applied for both 384MHz step and lower ones)
15/09/2015 - r361 :
- Fixed no mobile network issue on DEB
- Disabled unnecessary debugging
13/09/2015 - r360 :
- Merged with android-5.1.1_r0.17 changes

- Updated F2FS
- Updated BFQ to v7r8
- Added experimental Nvidia relaxed power savings
- More fixes and various optimizations regarding performance and efficiency
09/09/2015 - r353 :
Note : CM related issues some are encountering aren't adressed with this update. CM team is breaking more and more stuff while using AOSP bases for the kernel and I won't make a CAF based version again. The updated toolchain and added fixes in this release may or may not help, but I won't provide support for CM related issues anymore. Sorry for the inconvenience.
- Fixed SELinux switches (You'll need to use the restore function in full package or just the restore package to switch between permissive and enforcing modes. Enabling it in glitch-settings.conf isn't enough for it to work.)
- Disabled Android Logger by default for less overhead
- Updated toolchain to Linaro GCC 5.2.0 with LTO support
- Tiny fixes
02/07/2015 - r350 :
- Merged with android-5.1.1_r0.13 changes
- Fixed missing governors from previous release
- Added native support for Xbox One controller from Linux 3.17
- Fixed a potential instability case in idle state
- Updated base to linux 3.4.108
- Under the hood fixes
- CM and AOSP kernels are now sharing the exact same base for better stability and maintenance
08/05/2015 - Hotfix - r344 :
- Rolled back various GPU driver patches to fix some Chrome scrolling lockups and possible RR linked to the underlying bug linked to them
- Send enforcing=0 to kernel command line if you're using the permissive ramdisk mode (may fix boot on some non-standard roms - AICP still not booting for me though.. If you know why I'm all ears)
- Modify fstab.flo file in ramdisk even when using CM kernel (enables some non-standard CAF based roms with no "multi-mount fstab" support to boot - it mustn't exist, but better safe than sorry)
08/05/2015 - r343 :
- Merged with android-5.1.1_r0.10 changes
- Removed UKSM
- Disabled KSM
- Removed transparent compression support
- Replaced Flar2's S2W/DT2W by showp1984's DT2W
- Various F2FS changes from arter97 and Jaegeuk Kim
- Various backported drivers from arter97
- Updated Intelli-Plug
- Cleaned up base and bumped back to latest 3.4.y (3.4.107 atm)
- Enabled back kernel mode NEON
- Removed PIE bypass patch from Aroma
- Added Motorola's Qualcomm optimized memutils
- Added BFQ v7r7 ioshed
- Updated Intelliactive governor
- Fstab patching changes to fix boot on some non-standard roms
- Updated Random
- Updated toolchain to Linaro GCC 5.1.0 with LTO support
- Added LTO optimizations
19/04/2015 - r330 :
After breaking my partitions while attempting to improve F2FS mounting time, I was forced to format everything. After my backup restoration and system reinstallation, r327 F2FS implementation is now booting faster than EXT4 on my tab (with mounting times of ~5sec versus 30+ before). So I've then decided to revert the planned F2FS changes for r330 (which made it 1sec faster before formatting, but much slower after) as it didn't make sense. If F2FS mounting time is bothering you, fully formatting your partitions and restoring your data will give you a nice performance reward in return.
- Added flush_merge to F2FS mount options for faster flushing
- Added "transparent compression" support (CM sync)
- Added back optimized ARM RWSEM algorithm
- Enabled back unaligned memory access
- Switched to SIO ioshed (from ROW) at boot time as well as others small tweaks for possible further boot time improvements and smaller file size
16/04/2015 - r327 :
- Merged with android-5.1.0_r0.10 changes
- Updated F2FS implementation using Motorola's sources
- Cleaned up permissive ramdisk patches (fixed related SODs with it enabled)
- Introducing "restore" builds. You can now update your Glitch setup without Aroma using these builds. Your settings will be restored from the SDcard backup made by a previous Glitch installation, so if you don't have a "glitch-settings.conf" file in the root of your SDcard, please use a full build first to generate it ! The "full" builds are using Aroma as before.
- Updated toolchain to Cortex A15 optimized Linaro GCC 4.9.3-2015.03
07/03/2015 - r320 :
THIS UPDATE WILL NEED YOU TO REINSTALL YOUR ROM AND TO MAKE A FULL INSTALLATION OF THE KERNEL IF YOU'RE COMING FROM A PREVIOUS GLITCH RELEASE
- Updated F2FS implementation and bumped to latest
- Various scheduler optimizations - Better hardware use means potentially lower max OC !
- Improved boot times (At least with EXT4. F2FS mounting time feels a bit longer with the updated F2FS implementation)
- Reverted Slimbus OC as some users got issues with it
- Removed some ramdisk mods interfering with permissions
- F2FS/EXT4 detection script rewrite to preserve rom's fstab structure
- Added another permissive switch to disable SELinux enforcing (it will be enabled if you tick the permissive patch in aroma)
- Removed wifi patch from Aroma as it's now useless with lollipop
- Added some security patches from CM source
- CM kernel rebased on Glitch AOSP (again) - Looks good after a few days of intensive use
- A few little glitchy tweaks
- Updated toolchain to Cortex A15 optimized Linaro GCC 4.9.3-2015.02
16/01/2015 - r307 :
- Disable wake gestures by default
- Fix for a little color tweaking bug
- Updated CAF variant for CM12 support & sync with Glitch AOSP r307
Note : r307-CM is NOT compatible with CM11. It must be used with CM12 only.
12/12/2014 - r306 :
- Added vmalloc setting to command line to fix some video playback issues. Thanks to @szale9001 for pointing this out !
16/11/2014 - r303 :
- Added Chainfire's partial root ramdisk patch by default
- Added cernekee's PIE patch to Aroma (allows third party native executables to run, lowering security. Fixes various apps)
- Added SELinux permissive + sepolicy ramdisk patch to Aroma (enables full root access but lowers security. Fixes various apps)
15/11/2014 - r300 :
- Updated AOSP kernel with lollipop-release - BREAKS COMPATIBILITY WITH 4.4.x due to GPU driver changes !
- Removed interactive GPU governor
- Merged GPU patches from codeaurora & franciscofranco for better responsiveness and battery life
- Cleanups
26/09/2014 - r226-disabledAVS :
- r226 variant with disabled AVS for users with recurrent instability issues. Higher power consumption than standard build when used without uV.
Follow up to this post : http://forum.xda-developers.com/showpost.php?p=55566837&postcount=1943
22/09/2014 - r226 :
- Added experimental support for Kali Pwn Pad (as it was requested by some - Thanks for the list Flar2 )
- Disabled compaction (a little higher RAM consumption for higher performances - Doesn't seem to affect multi-tasking in a negative way)
- Disabled MSM hardware adaptive voltage scaling (should fix the last remnants of SoDs/RR happening for some even on other kernels - May lead to higher power consumption) I will make a test build with it disabled for who wants to try in the next days
- Updated Faux Sound to 3.6
- Enabled more TCP congestion-avoidance algorithms
- Enabled NFS support
- Moved exfat to built-in instead of module
- Added black magic

- Lowered "Glitchy" L2/bus settings to make it usable by more users
- Enabled various compiler optimizations (like some GCC graphite optimizations)
- Updated toolchain to Cortex-A15 optimized Linaro 4.9.2 2014.09
- Echo touch firmware version to logfile (/data/local/tmp/glitch-kernel.log)
10/09/2014 - r220 :
AOSP kernel only (CAF kernel will follow as soon as possible) :
- Rebase using latest Google source (fixing various bugs like SoD, random shutdown, slowdowns etc.) and staying on 3.4.0 base for now to prevent issues til I'm able to fix them all with latest Linux upstream
- Aroma Installer rework for less pages on fresh installation mode, similar to Flar2's presentation
- Added new options to Aroma installer
- Updated Flar2's S2W/DT2W system, enabling gesture support
- Replaced Showp1984's MPDecision by Fluxi's MSM Hotplug driver - new default
- Updated Faux123's Intelliplug hotplug driver as well as intellidemand & Intelliactive governors
- Updated/fixed Smartmax and Smartmax EPS (extreme power saving) governors
- Updated FauxSound
- Updated Flar2's msm_sleeper
- Added a backlight dimmer function
- Cleaned up/removed a vast amount of old patches
- Added release number to internal kernel naming so you know what version you're on
- Added a wlan firmware override setting in Aroma. This is basically the same as using 4.4.4 PRIMAtor to enable 4.4.3 or lower support or to fix wifi on a few roms that are using older wifi blobs
- Slight tweaking here and there
- Removed kernel-based NEON support - Needs more testing
- Switched to LZ4 kernel compression - Higher kernel size but faster boot times
- Updated toolchain to Cortex-A15 optimized Linaro 4.9.2 2014.08
05/07/2014 - r151 :
AOSP kernel only :
- Base update from Linux 3.4.86 to 3.4.96
- Removed some unnecessary Aroma pages for faster navigation
- Removed Qualcomm-Optimized Dalvik/Bionic from Aroma to prevent users from softbricks when used on incompatible ROM
- Added F2FS support
- Added F2FS partition detection script to modify ramdisk accordingly at flash time. You will need to launch Aroma installer each time you change FS on supported partitions (DATA, CACHE & SYSTEM) to refresh the ramdisk configuration (you can restore your glitch settings to do that btw, no need to clean install). You can use all of them as F2FS, or just one, you decide.
- Enabled Intelliactive governor

- Added 81 MHz CPU frequency
- Updated ondemand governor
- Switch to Cortex-A15 optimized Linaro 4.8.3 toolchain
- Disable input-boost by default in Aroma
07/02/2014 - r140 :
- Update to Linux 3.4.79
- Switch to XZ compression
- Add kernel mode NEON support as well as NEON accelerated AES & XOR implementations
- Fix CPU load miscalculation
- jbd2 and ext4 optimizations
- Add max screen off frequency support - Thanks to Flar2 (if disabled in Aroma, changing frequency in apps won't have any effect)
- Add UKSM 0.1.2.2 support
- Add dynamic management of dirty page writebacks
- Enable Wiimote HID support
- Enable USB printer support
- Bugfixes
Aroma installer overhaul :
- Reworked installation process to be clearer and more customizable
- Added an automatic backup of your settings to the root of your internal SDcard
- Added a restoration mode to get your settings from internal SDcard backup back on any rom (cross-compatible with Glitch kernel variants)
- Renamed /system/etc/settings.conf to glitch-settings.conf to make it more obviously glitchy
- Removed the need to set CPU OC, L2/cache OC and auto-uV again when keeping previous settings (now reading it from your settings at flash time. Note : editing this part in /system/etc/glitch-settings.conf requires a reflash using the "already glitched" option)
- Added Qualcomm optimized Dalvik/Bionic libraries into the installer (bionic only on CM variant) so you can install/restore them with the kernel
- Added I/O scheduler, CPU governor, read-ahead buffer size, fast charge, max screen off frequency and maximum multi-core power savings to available settings
- Fixed how the min CPU clock is applied to make it more robust and work better with governors
- Fixed how the min CPU freq uV is applied to make it work independently of the min freq (by subtracting the uV amount to the original voltage instead of forcing plain values) - Also, make it capable of setting uV for all freqs for future use.
- Changed the auto-uV menu to reflect the internal changes
- Fixed some permissions issues
- Added hotplug driver check so it's possible to restore it as well from settings without interference
- Change theme

- Faux123's LCD color control driver updated to Flo version (thanks to him to make it opensource), adding gamma control. (You'll need FauxClock to tweak it - color is still available from TricksterMod)
- Some GPU driver related bugfixes
- Implemented LoUIS API for cache maintenance operations
- Update base to Linux 3.4.77
- Revert some CAF updates (fixes some L2 corruption that could lead to random reboots / black screens)
- Battery life improvements
- Some cleaning

Thanks.
That's what I'm trying to make. And I *think* (may be wrong though) I'm the only one yet using a fully working GPU OC implementation on flo kernel. It's an adaptation of Galaxy S IV's (i9505) GPU OC code from Team Hydra.
It seems 627 MHz is around the max possible with stock voltage, probably even 600 MHz for many. I'll see what it can do with a bit more juice.
Other things to do : add more frequency steps for the CPU, lock the default freq, and make the L2/bus speed configurable.
After that I think we'll be able to push the thing to the limits if we want to.
Thanks for your hard work I'm going to try it on pacman ROM I'll let you know how it goes

I wanna show u my settings, I use trickster, so sound and faux kernel app to get the results I need was going to show you pictures but all the sudden XDA premium has no picture button I'm a little lost their. Touch responses phenomenal and just like faux kernel the sound is this did really well I can finally listened stock sound sucks on this product even know what has supposedly way better speakers, thanks to people like you I can actually hear the videos I watch without headphones now. Thank you very much I've been using it for about 5 minutes swimming around on everything and everything smooth as hell

The problem exists on the free app as well ^^
Try scrolling up and down away from the images and back on them, it'll eventually show up at some point.
Thanks for your work. I'll give this kernel a try.
Coming from N4 motley kernel I'll love to use init.d scripts to set up color "calibration", sleep states, etc. What do you think about implementing / documenting such features for your kernel?
Otherwise, let me see if I need something. Hm, what about USB OTG and ntfs/f2fs support?
USB OTG is working out of the box. NTFS/F2FS support isn't. I'll look into adding them =)
Your idea is nice, I'll think about it.
Thanks =)
Do you plan on adding Faux's color mod? I will give this kernel a shot and report back.

I am running the kernel right now. All I can say is "wow".
You did a fantastic job cherry-picking the best features from various kernels. I notice a slight increase in smoothness compared to Faux's kernel plus D2W and all the other great features you added so I think this may be my new main kernel.
I will use it over the next few days and report any issues I find and how the stability is. Thanks a lot for your work.
Edit: Also, I am running CleanROM and everything seems fine.
Thank you, so it may work with any rom then ! Good to know CM didn't break too much stuff leaving AOSP base.
sleep to wake, doubletap to wake disabled by default? don´t need it xD
need a fast stable kernel and especially want to disable fsynch. if u run a stable rom it justs takes useless power xD
i´m pretty new to the nexus7 like the most of us . is that kernel stable?
atm i´m using faux´s, also used franco. i dunno, but on franco´s i couldnt change gpu govenor and the 3dmark benchmark was about 3000points, stock is about 6000-7000. pretty strange.
i am a pretty minimalistic user, want best batterylife/performance ratio. only using psx, best rom for me
i think i´ll try that kernel
edit: what does "Snake Charmer" do?
edit2: read s2w stuff enabled by default, can it be disabled via trickster?
My N7 is running great with your kernel. Let's see what about perfomance and stability in two or three days. After checking and playing with trickster I miss a kind of dynamic fsync and a color calibration interface - compared to N4 m+ (motley) kernel.
Perhaps you can implement some upstream changes / patches directly from CAF or newer kernels.
It would be nice if you post some information about L2 speed hack, etc. So that everyone can see what this hacks do.

/* To kang or not to kang */
I prefer "open" to all stuffs, explicitly except for my personal kernels.
I've once used to use private Git repository for my kernels and just release the source-codes as a tarball,
which means that other developers who are interested in my kernel's changes would not get the specific changes they want while not violating XDA forum rules or GPL.
That was almost 3 years ago which by then, I was a newbie developer on XDA.
I was afraid other big developers merging all of my changes and I'll get buried down.
However, I've changed my mind and opened up my Git access to everyone after thinking my previous actions did not belongs to XDA's spirit.
That was a big move for myself of re-thinking what should be open.
Later down on the road as I gained more development skills, I've contributed into CyanogenMod and other's custom kernel and ROMs for fixing stuffs, introducing new concepts or improving performance.
During such process, there were quite a lot of occurrences where I was actually the first one to do those things.
For those who're familiar with "temasek ROM", you may know that after I became a contributor, temasek rose even more into the center of other AOSP ROMs' attention, as I was the first to introduce new exciting stuffs such as compiler changes or f2fs. And I quickly gained dozens of followers on my GitHub account.
And eventually, people *kang*ed my changes. Sometimes invalidating my authorship.
It surely is not a right thing to do, but I let it slide as it didn't matter that much. I believed that if my changes are good enough, it'd be better to end up with a larger user base rather than being a **** trying to hunt down every ROM developers who're doing it wrong.
Same story goes to my ROMs.
My real first popular ROM was back-to-n00t, which is a ported ROM from Galaxy S3 LTE to provide stable Touchwiz KitKat experience to the Galaxy S3 3G users.
I opened up everything to GitHub. And I even encouraged that other ROM developers to use my ROM as a base to work on their own ROM as I knew there are a lot of Touchwiz ROM cookers who're way better than me on modifying SystemUI or frameworks(via smali) BUT aren't too good on porting ROMs. I hoped that my ports can be a great base for others to work on their own modifications.
Now those spirits repeated on the Galaxy S6, I opened up everything about back-to-n0t3.
However, I do not do or believe those same things with the kernels.
There are far less kernel developers on XDA compared to ROM developers. ROMs are much more appealing for an "Android newbie" to go tweak. You can modify UI, enable some hidden settings and even port features from another devices.
So when ROMs gets copied off, users can easily distinguish if that was stolen or not.
Let’s say a well-known developer A ported S6 designs and features to the S4. Next day, less-known developer B uploads a ROM on XDA that claims to do the same thing. First thing that comes to the users’ mind would be ‘Is that guy a thief?’.
However, same thing cannot be said on the kernels as they work on a much lower level. You can’t distinguish individual custom kernels just by staring at your phone.
If a ROM developer choose to go use other’s custom kernel and integrate it into their ROM, it’s most likely that users won’t appreciate that custom kernel developer whose work powers that ROM. Let’s face it, not all users care about “Thanks to”, “Credits” sections, and let me tell you, those are the majority. Now some custom kernel developers might be OK with that. However, I’m not. Unlike most developers on XDA, I got fascinated to Android because it runs on Linux kernel. Modifying Linux kernel was the first thing I’ve done on my Android device, not modifying ROM. And I spent years and years on gaining information on Linux/Android kernels and tweaking, coding myself. While I don’t necessarily care users choosing to NOT use my kernel, I cannot stand that my kernel would be installed on one’s device which its owner don’t even know which kernel, which developer who made that kernel is. That is why I’m against with the idea of integrating custom kernels into custom ROMs. If you want your users to have a custom kernel, let them learn themselves what that kernel really is, what does it offers, and who developed it. “For the ease of flashing/installation” is not an excuse for me. Take yourself a few more minutes to download a kernel from the web, and a few more seconds to flash a secondary ZIP file from the recovery. Is that hard? Time-consuming? Absolutely not.
I hope everyone gets the idea why I'm sticking with the idea of "don't integrate my kernel into others".
Cheers.
/* Customizing kernel */
You can install Synapse from the Play store to control voltage and other frequencies.
To control some core kernel parameters, create /sdcard/arter97 as a directory and do the followings
--- Enable Adaptive LMK ---
Enabling Adaptive LMK will increase responsiveness at the cost of reduced multitasking capabilities and battery life.
Create a text file with 1 letter "0" under /sdcard/arter97 named "adaptive_lmk" and reboot
--- Disable LED fade ---
If you have issues with other 3rd-party LED controlling apps, try disabling it.
Create a text file with 1 letter "0" under /sdcard/arter97 named "fade_led" and reboot

I don't understand why everyone is testing if phone call works fine.
Was that an issue on the existing custom kernels? lol

Other custom kernels had random reboot issues. Most notably, they would reboot after a few minutes of a phone call.
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.

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.

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.

Changelogs:
Version 1.8
*Added LED fading control made by @AndreiLux
Version 1.7
* Fixed interactive governor logic. I forgot logic code for CPUFREQ_RELATION_C. Now interactive is 50% more responsive.
* Backport some ASLR changes
* Added ZEN IO scheduler and set it as default (beware that Synapse will auto reapply YOUR settings after boot, so ZEN won't be set. If you want it set it in Synapse I/O tab)
* updated GPU ION memory allocation code
* Exposed HMP up/down threshold tuning in Synapse ---> "HMP tuning" tab
* Fixed false adaptive LMK triggers --> less RAM clearing when not needed
Version 1.6.1
* GPU control code revamped
* GPU frequency scaling logic revamped. Fixed various bugs introduced in stock and in min/max control code + optimizations
* Synapse: added monitoring current values for DVFS Interactive governor (for GPU).
* DVFS Interactive governor is now working very good.
* Sensorhub wakelocks reduced (sensorhub and ssp wakelocks)
Version 1.6
* Disabled TIMA and some other Exynos specific non needed stuff
* New GPU Governor - Interactive
* GPU governor Interactive tunables exposed in Synapse
* Many GPU control code optimizations
* Reverted to stock DVFS OC table
* Fixed DVFS table for our SoC
* Set SELinux permissive on boot --> But after 20sec some ROM binary sets it back to enforcing.
Who wants SELinux permissive, he can set it in Synapse. But ROM boots permissive
* Better min/max GPU freq guards
* Updated touchscreen with powersuspend driver to see if it's possible to use wakeup gestures.
Version 1.5
* Disabled GPU tracing to squeeze out 3-6FPS more in games. Also should run smoother now.
* Framebuffer cmap buffer overflow check
* GPU OC --> 600MHz and 677MHz steps
---> use very carefully
* GPU min/max clock control
Version 1.4
* LMK fix
* Beefed up ASLR to give hackers more headache now if they try hacking the phone
* Upstream commits for lowlevel ARM optimization from ARM themselves
* New compiler flags. Should run about 40% faster
Version 1.3
* IRQ code updated --> critical code updated
* updated NET code that works with internet
* ALSA and Arizona (WM5110 audio chip in our phone) fixes
* SCHED, TIMER, RCU code updated
* REGMAP updates
* MM: new shrinker API --> many drivers use this (such as LMK)
Version 1.2
* Fixed critical bugs in ADJ RBTREE code, used by LMK driver
I recommend you to critical update kernel now.
* Disabled adaptive LMK by default and added userspace switch to turn on/off adaptive LMK in Synapse (in Misc tab)
* Tuned LMK minfree values.
* Updated BINDER and FS critical code
Version 1.1
* Fixed Synapse power efficient workqueues checkbox --> now works good
* Disabled PE workqueues by default
* Added SELinux enforcing/permissive switch in Synape (it's last checkbox in Misc tab)
* charge_control: new charge control made by @duki994 (me) (based on @Lord Boeffla's code, but refactored and reworked from scratch)
-->It's harcoded in max77804 charging chip. Now charge control should work and obey set values.
* Fixed miscellaneous things

Known bugs:
* Turning headphone EQ on will lower headphone output volume.
* If you set any of Headphone EQ bands to 3dB, Wolfson audio chip will produce very unpleasant noise and stop playing.
It seems that it's inner HW components don't like that gain.
Every other setting will work, just don't set any band to 3dB Works after audio updates
* Charger controls for AC current are not reacting to change.. New charge control driver is good now.

CPU OC is unnecessary for our device.
And CPU underclock won't save more battery.
It'll actually drain more battery.
On very low freqs CPU can't finish task and needs to bump freq up. The freq changing is much more power costly than being on stock 500mhz min for A7 and 800mhz min for A15.
Look at power curves.
We have power curves similar to those on 5433, just about 20% lower I think
This are high performance cores (A15, A57, A72...)

"lightbox_toggle_sidebar": "Toggle sidebar"
}
And this are for power-saving cores (A7, A53...)
The shape of curve for our chip is almost same, only with lower consumption. Look how exponentially it increases as you put frequency after 1.2GHz.
So if I enable OC to, let's say, 2GHz, then power consumption would be 20% higher than on 1.9GHz and performance would be 4% higher.
But don't let that fool you. Phone may last 2s-3s on 2GHz. Then it would throttle down when it overheats due too much power dissipation.
So in the end you get much lower performance than you would have on 1.9GHz.
And keep in mind that Exynos 7420 is built on 14nm FinFET technology, and Exynos 5422 is 28nm HKMG.
So we may use a bit more power than 7420.
My observation:
I get maximum performance on 1.8GHz. Phone is heating at least 10 celsius degrees less than on 1.9GHz so almost no thermal throttling.
For games and high performance apps, I suggest that you lock A15 core cluster on 1.8GHz.

kernel still enforcing,hope can permisive next build,hard 2 install audio mod like dolby
hope there will be overclock options and lower min freq.
the gpu voltage @266mhz weirdly high @default in synapse.
cpu workqueu checklist doesnt stick after rebot
kernel dont boot in BPC4 but runnin fine in BPC8 strange because i use the same BL
stuttering in music with screen off
other than that great kernel waiting 4 d next build
Good work.. Thxx
nice work mate... phone is not laggy now..
Bro I guess selinux is still enforcing. can we get a permissive feauture in next update.

I know about PE switch. I mady typo in ramdisk. Will be fixed
I use BOL2 ramdisk and BOG4 (latest kernel sources given by Samsung).
It should also work on BPC4. But use BPC8 if it doesn't.
GPU voltage is bug or made intentionally by ARM/Samsung. I lowered it to 25mv higher than 177mhz voltage and it works.
Also new charging driver made by me will be included in next release for testing

Probably SELinux enforcing.
I will leave it on by default due to Stock ROM apps need, but I'll add checkbox/switch in Synapse to switch it enforcing/permissive. It should fix those problems with dolby sound.
Why install Dolby sound? WM5110 is awesome and as good as my ASUS Xonar Essence One DAC. And I'm audiophile. That's why I bought this phone

nice work mate... phone is not laggy now..
Bro I guess selinux is still enforcing. can we get a permissive feauture in next update.

I will also disable PE workqueues by default. They drain battery more in heavier usage and make sound stutter.

Installed.. And using it as it is.. But having more battery drain than stock kernel..
Where did i go wrong?
Thanks mate

Hi @duki994, would you be able to include doubletap2wake or swipe2wake in your kernel in the next release or future releases? It will be really cool if the phone wakes up on double tapping the screen!!! THanks
Version 1.2
Changelog:
* Fixed critical bugs in ADJ RBTREE code, used by LMK driver
I recommend you to critical update kernel now.
* Disabled adaptive LMK by default and added userspace switch to turn on/off adaptive LMK in Synapse (in Misc tab)
* Tuned LMK minfree values.
* Updated BINDER and FS critical code

@jawzf
Yeah. That would be cool. I have exams next week, so I don't know if I can merge those changes for sweep/tap functions until then, but I want those features too. I come from G2.
Double tap is natural to me. Maybe only sweep functions can be implemented. I know LG's double tap drivers. It's coupled with custom synaptics touch chip firmware which has HW level support for double tap,
Note that sweep/double tap funcs may drain much more battery. And our driver is different from G900F.
But I'll merge and adapt 'em when time allows
EDIT: Charge current control driver is working as it should
Well looks like is time to test your kernel

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 and is based on stock BOL2 source
Features:
* Wolfson Audio control adapted to G900H implementation (thanks to @AndreiLux)
* Battery charging current control
* 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
* MM and FS powersuspend mods ported from @dorimanx's LG G2 kernel
* SCHED code fixes
* SCHED: HMP thresholds changed and new patches implemented
* OF code updated --> better/faster reading of DTS and faster operation
* Many changes related to ARM instruction code and lowlevel ARM core management
* Enabled NEON mode in kernel with full VFPV4 support
* Added new SHA256 , SHA512, SHA1, ASH2 and AES NEON accelerated algortihms - now blazing fast
* 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)
* WiFi: fixed enormous battery drain during standby/suspend
* NET updates
* LMK updated and added new feature: Adaptive LMK --> better multitasking
* Enabled all TCP congestion protocols and set Westwood as default (best wireless performance)
* Disabled KNOX
* Wakelock disabler: You can disable some common Samsung wakelocks in Synapse "Misc" tab if some of them are draining your battery
* Fully configurable in Synapse (download from Google Play)
/* Important note to other devs */
You cannot include this kernel in 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, as so people would know where to ask if kernel problem arises. I would do the same for you
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 that can't handle low voltage.
If someone happens to have bug with WiFi saved password being lost every reboot, here is fix:
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 CAN make your WiFi forget password each reboot. 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.

Known bugs:
* Turning headphone EQ on will lower headphone output volume.
* If you set any of Headphone EQ bands to 3dB, Wolfson audio chip will produce very unpleasant noise and stop playing.
It seems that it's inner HW components don't like that gain.
Every other setting will work, just don't set any band to 3dB
* Charger controls for AC current are not reacting to change.. New charge control driver is good now.

Hello!
I want to introduce my first custom kernel for the SM8250 family of Snapdragons. This is based of latest Samsung OneUI 2.5 Sources and I cherry-picked commits to make improvements to the stock base. I'm not a developer, but i really like to port stuff over .
I will try to have this Kernel updated as soon as new source tarballs are drop by Samsung. If you want to request for specific features, let me know and i'll do my best to bring them over.
Special Features:
Changelog is in post #2
How to Install:
First, make sure you are in any OneUI 2.5 (BTH* or BTI*) ROM and have TWRP on the device. Make sure you take a backup of your current boot partition in twrp, now install either the boot.img (extract from the tar file) or use ODIN to flash in Dowload mode. Please make sure to read Post #3 regarding issues with the current OS Patch Level. Images from 1.5.0 onwards are pre-rooted but you will probably need to update magisk either manually or by flashing latest magisk.zip file.
Keep in mind the following table to determine your phone model:
x1q = S20 - G981X
y2q = S20+ - G986X
z3q = S20U - G988X
r8q = S20 FE - G781B
c1q = Note 20 - N981X
c2q = Note 20U - N986X
IMPORTANT NOTE: It seems some users need to flash a vbmeta image file provided by Google in order to boot and user the Custom Kernel. If you find yourself in a situation were you are not able to boot, please flash the attached vbmeta img along with the Kernel and if still bootlooping share the last_kmsg to determine what's driving the issue.
Download:
Disclaimer: I am not responsible if you use this and brick your device or if your device blows up, implodes, flames start shooting from it or it kills your neighbor's dog. Flash at your own risk. I am not responsible.... It was the other guy... I swear....

Added a fix to hide Magisk Mount for Isolated Processes. This is a critical leak in MagiskHide that can be exploited by apps trying to determine if the device is rooted. I had an issue with two payment apps that after applying this fix, they work. Not sure if they were finding magisk with this method lol. Read more here https://darvincitech.wordpress.com/2019/11/04/detecting-magisk-hide/
Finally removed the warning upon boot. EdXposed compatibility was not affected by the removal of it.
10.27.20 - JimboK-1.5.0
Rebased to S20 FE source as baseline for all models. This is to ensure support for the S20 FE is added and to keep the most up date source from Samsung
Streamlined even further the 'common' defconfig and updated all other variant defconfigs to make it easier to build individual Kernels.
Removed GPU OC - This is to test drive if performance takes a small hit but battery is gained. I have this as *temp change* consider it a 'test' phase so i will need your feedback on it to see whether if we keep it or not. Also, the OC was causing issues to boot in N20 units and some weird hiccups in the System-UI for my S20U.
Added BBR2 TCP CONG protocol. By far, the best TCP CONG to speed up the network connections overall. Read out more here: http://dl.ifip.org/db/conf/networking/networking2018/2B1-1570416152.pdf
BBR2 is now default TCP CONG for the Kernel. I recommend ya'll to make the switch
Several Upstreams to NET/TCP in order to improve Network Connectivity and Speed.
Kernel comes pre-rooted now (via ramdisk). In the event of a magisk update you will only need to update through Magisk Manager. This is for the sake of simplicity
10.16.20 - JimboK-1.4.0
Removed several DEBUG options from defconfig that should not be present in a Production Kernel
Disabled ZSWAP and VBSWAP (this will create conflict with ZRAM) and ZRAM has proven to be more effective and create less wear than ZSWAP
Disabled LZO, updated LZ4 compression algorithms
Enabled ZSTD Compression, it is recommended to enable this for ZRAM moving forward
Disabled KPERFORM in defconfig
Enabled .gz compression for Kernel. Kernel is now almost 1/3 in size of what it used to be
Added and Enabled HID: NINTENDO SWITCH controllers support
10.13.20 - JimboK-1.3.0
Unified Sources a bit more. Removed the individual defconfigs to have one single plus each variant
for X1Q and Y2Q moved dts sources from CHN OPEN to KOR to keep it in line with main (Z3Q) sources and also for CXQ sources. BTI3 (latest software release) is now used for those models.
Enabled a few drivers inside of Kernel: CDC, NTFS, CIFS and some native gaming devices as well
Disabled DM_VERITY checks. This will help with the booting times

OS PATCH LEVEL set as 2099-12 (Read post #3 - Mandatory)
OS PATCH LEVEL PROBLEM
This is a modified version of @evdenis post HERE
My Kernel uses an OS Patch Level of 2099-12 to maximize its compatibility among all releases by Samsung across all the supported phones. That's it. No other reason as to why choose that date, now, when you continue using my Kernel update after update there will be no issue, but if you change the kernel to any other (specially stock) chances are that Kernel is using the current month OS PATCH LEVEL which will cause two things:
You will not be able to pass beyond your lockscreen. No matter what you try, it won't let you unlock upon reboot
Your Samsung Account will warn you to log off and log back in but you will not be able to do so
The problem is not in sources. It's due to os_patch_level mismatch with you current kernel. As mentioned JimboK Kernel does not uses common security patch date to be in sync with the official samsung firmwares. You can check the default os_patch_level in build.mkbootimg.* files. However, this date can be higher than other kernels use. When you flash a kernel with an earlier patch date on top of the previous one with a higher date, android activates rollback protection mechanism and you face the problems stated earlier. It's impossible to use a "universal" os_patch_level because different users use different custom kernels and different firmwares. JimboK Kernel uses a highest date by default in order to suite most of users.
How can you solve the problem? 6 ways:
You can restore my kernel and the problems will be gone
You can flash the attached zip file. backtothefuture-2099-12.zip, it will make your new Kernel Patch OS Level 2099-12 thus avoiding the issues above. - read more about the zip HERE. You will have to flash this with any new kernel if you ever use mine (unless you do a full wipe as mentioned at the end of this list).
You can check the os_patch_level date of your new kernel here https://cruelkernel.org/tools/bootimg/ and patch the kernel image image to the same date. If your previous kernel is mine (JIMBOK), patch your new Kernel to 2099-12 date.
You can reboot to TWRP, navigate to data/system and delete 3 files those names starts with 'lock'. Reboot. Login, set a new pin. To fix samsung account login, reinstall the app
You can rebuild JimboK Kernel with os_patch_level that suites you. To do it, you need to change the OS PATCH LEVEL to the desire date when using mkbootimg.
You can do the full wipe during the new Kernel flashing
Update 10.20.20
Updated the zip file to add support for W models.
Update 10.19.20
Updated the zip file to remove Exy devices and focus solely in N20 and S20 Snap line.
Finally kernel for s20 thanks a lot.
Works great!
I've got bootloop with my S20U G9880 after flashing this kernel even with a full wipe

Strange I have G988N which is just about the same and I don't have that issue. Did you come from a rooted device? Were you in a custom ROM before?
Can you tell me a bit more of your setup?
Are there any other G9880 users with the same issue?

I flashed this and did a minor debloat and gained roughly 30 minutes of screen on time.
I also noticed the animation from recents to home screen is slightly snappier.
Could be placebo but I like it.

Hey man, how's it going? Did you do anything special to get kcal working on the kernel? Mental made a kernel for the Note 20 Ultra but said he could not get Kcal working.
Also, even better, would you consider making a common kernel for the Note 20 Ultra Snapdragon? I'd definitely send a donation your way.
