/* More informations */
Based on stock SHV-E210S kernel source
Samsung has put massive updates in their Android 4.4 kernel compared with Android 4.1 kernel. By being based on stock SHV-E210S kernel source, arter97 kernel is miles ahead of where other CyanogenMod-based kernels are slowly catching up behind.
Dual-booting
arter97 kernel implements simple yet seamless multi-boot solution that does not need a dedicated recovery. It's also faster, thanks to raw extracted method instead of slow loop mounted images.
To start, enter recovery(CWM, PhilZ) and flash arter97-multi-boot.zip. The ZIP files you flash afterwards will be stored in the 2nd-ROM slot(/data/arter97_secondrom) until you exit or restart recovery.
Reboot back to 1st-ROM, and use newly installed 'aSwitch' to control 2nd-ROM. You cannot select between two ROMs on the initial start-up time.
* 2nd-ROM's /system partition will be always mounted R/W due to its limitations.
* Backup & restore will not work for 2nd-ROM. Don't try it unless you want your entire device screwed all over.
* Do not select data wipe on 2nd-ROM installation! 1st-ROM data might be lost instead.
Advanced mDNIe control
arter97 kernel offers advanced mDNIe control by AndreiLux, leaving every single controls available for the screen in the palm of your hands.
Knock-On
arter97 kernel offers full Touch Wake functionality(by Ezekeel & Yank555.lu) with additional 'Knock-On' feature. Within the desired timer you set, Touch Wake will only work by double-tapping.
Touch Wake
Touch Wake has been improved in arter97 kernel. Not only the implementation of 'Knock-On' feature, you can now set a seperate timer on charge, force to also work on physical button pressed.
Compiler
arter97 kernel uses the latest Linaro-toolchain. Linux kernel's compiler profiles has also been backported from Linux 3.16 for more compiler bug-fixes, performance improvements.
Memory managements
arter97 kernel is fully upstreamed to the latest Linux 3.0.101. This provides improved stability, performance and memory management. But many developers forget to properly match Samsung's CMA memory management to Linux 3.0.101. arter97 kernel is the only kernel properly upstreamed to Linux 3.0.101 with CMA, meaning better memory management than other kernels.
If you're using Android 4.4 KitKat, ROM can work together with arter97 kernel which improves memory managements even further.
File-system
Battery and access speed to /sdcard is also improved by utilizing Samsung's sdcardfs and ditching Google's fuse implementation. Users can disable sdcardfs allowing FolderMount to work properly.
FAT32 latency is improved, and AIO(Asynchronous I/O) is backported from Linux 3.6 with latency improvements.
f2fs
arter97 kernel is the first Android kernel(since 2013/08) to feature full f2fs support with selective partitions preferences. If you manage to make a switch from ext4 to f2fs, theoratically, your device's flash storage can perform up-to 2x faster. arter97 kernel also continously backport the latest f2fs from Linux 3.19+. This f2fs will be even more faster, reliable than other Android kernels.
PhilZ recovery dedicated for f2fs makes users easy to switch. Install kernel and recovery, wipe /data and /cache, that's it.
Boeffla Sound Engine
Boeffla Sound Engine is the only custom audio engine available in arter97 kernel. Go and download 'Boeffla Sound Control' from Google Play store.
Android logger control
Android logger, aka logcat can produce a lot of garbage datas even when you don't need them. You can explicitly disable Android logger completely, or make it clear itself when the screen goes off(which is the default).
Mali graphics
arter97 kernel uses the latest Mali driver available for Samsung's Exynos 4412 phones, r3p2. It also uses the latest Mali blobs from N7100 ROM, which is built more recently than GT-I9300 ROMs.
Automatic kernel panic log dumper
When you use a custom kernel, you may experience unexpected malfunctions like sudden reboots. You should dump the kernel log and report it to the developer to help, but it may be very tiring to manually dumping and sending it. To make your life easier, arter97 kernel automatically dumps kernel log when kernel panic happens, and stores it on /sdcard/arter97.
Kernel-side Camera shutter sound control
arter97 kernel can force and turn off the speaker while the rear camera is operating. Since this is a kernel-side implementation, it doesn't need any ROM side support. Control available from aTweaks.
Powerboost
Powerboost is a function that dynamically boosts your device's performance when an external charger is connected. Since none of the power savings are needed while the device is charging, you can experience much more faster speed during that period.
Boost-boot
Boost-boot is a function that can reduce boot-up time up-to 20 seconds. It uses 'performance' CPU governor, 'no-op' I/O scheduler and 1024kB readahead when the device is booting.
aTweaks
aTweaks is a live-kernel-controller dedicated for arter97 kernel based on STweaks. You can control almost every aspects that arter97 kernel offers. Installing BusyBox before using is recommended.
aSwitch
aSwitch is a dual-boot settings for arter97 kernel. It can wipe 2nd-ROM's /system, /data and /cache. You can also set /sdcard sharing option within aSwitch.

/* FAQ */
I get 'status7' error while installing!
Your recovery is out-dated. Go and install a newer one.
Any recommended kernel settings?
The defaults are the most recommended settings. Try and use the default settings for several days before tweaking it yourself.
No GPU clock controls?
No. I personally don't like exposing GPU clock controls to users. I have no plans of adding these controls to my kernels.
I'm experiencing data-losses, device shutdown while downloading torrents!
Please turn off 'Dynamic Fsync' from aTweaks. Note that this may make your device slower.
Screen mode settings are not working!
mDNIe settings is moved to aTweaks. Please use the settings from there.
My screen color is inverted!
Tap the home-button 4 times. It's a kernel feature, please read the entire post.
The boot animation is laggy after installing this kernel!
The root cause is unknown for now, but it is normal and doesn't affects anything else.
Personal Hotspot is not working after switching to another kernel!
It's due to hostapd binary change. Go and re-flash your ROM.

Great work man
I am already downloading the note 2 KitKat port and will give this a shot.
Thanks for your support man :good: :good:

Installed on Achi Preview1 4.4.2 TW rom.
Booted fine - none of the 2 apps worked.
Lost root.
Manual installing root and returning here if any problems.
--EDIT--
After manual root install it works.
Just don't have the USB connection when using the apps, and it works fine.
THX for the initial kernel

Not installed im using kk Archi port ??

Shoot, it actually happened to me, I thought I'd installed the ROM wrongly, seems like the kernel may be the root cause.
Will try to fix it in 2.0.1... xD

/* User configurable vnswap toggle */
vnswap is a virtual ramdisk driver from Samsung that can be used with zswap.
The goal is to efficiently replace zram.
Enabling vnswap will try to compress 50% of your RAM, resulting in
6GB+ usable memory on Galaxy Note 3 and
4GB+ usable memory on Galaxy S4 LTE-A.
Enabling this will drastically improve multitasking experience at the cost of slightly reduced power efficiency.
This is recommended for users who heavily multitasks or do not turn off the phone for days.
This is turned on by default on all Touchwiz ROMs.
You can manually enable or disable it via writing 1 or 0 to /data/.arter97/vnswap and reboot.
(You will have to create /data/.arter97 directory and create vnswap textfile yourself.)
You can check if the vnswap is working properly by checking /proc/swaps

/* FAQ */
Why are other CPU governors disabled?
I personally don't want any of my users to play around CPU governors. It'll start be a mess when I try to add support for other CPU governors.
Can I use stock mpdecision and stock thermal engine?
This one too, I'd like my users to stick with Lazyplug and intelli-thermal. Stock implementation is faulty, cores can lock down with stock mpdecision. As for intelli-thermal, the benchmarking score may reduce but will help for a lower temperature of the device and increase the efficiency of the thermal control.
How can I switch to another or stock kernel?
You may have to reinstall the entire ROM. Wipe /system and install the ROM. The included addon.d script helps the kernel to survive on nightly upgrades, but you need to remove it or wipe /system to switch to another kernel.

The link for 5.0 touchwiz it s not working!!!

Just retry some times. It works

Great to see kernel supporting f2fs

Stock i9506 Lollipop support lacks a bit.
I can solve Wi-Fi now, but it'll still lack stability compared with stock kernel.
I'll rework after Samsung releases i9506 Lollipop kernel source.

The new kernel made me revert back to CM12 - happy for it! Even though the touchwiz 5 is not bad - CM12 i still faster/better. The only thing I miss is the native camera app and the s-view.
As always great job.

Does this support also CM11 ??

I agree with you. Camera app (using touchwiz Framework though) is the only thing that makes me stay on official samsung release.

Great if you can resolve wifi ! I think it's the only thing that does not work (with Knox boring notification that I don't Know how to resolve)

Unknown security issue is detected by system after installing kernel v4

Yeah, you get that on stock lollipop, better to use stock kernel on the official rom.

Version Information
Status: Stable
Current Stable Version: 2.4.2
Current Beta Version: 3.1.0
Created 2017-02-26
Last Updated 2017-07-26

Changelogs
While searching the Internet you might also find versions which aren't listed here: these are Beta versions and their changelog isn't available (but included in the one of the next stable version, so you don't miss anything).
All the changes I made are listed on GitHub.
Version 2.4.2
Code:
- update sdcardfs
- updated build scripts and recovery scripts
- changed toolchain to a better version (Linaro Android gcc 6.3.1)
- widely improved ramdisk scripts
- updated ramdisk to latest version from RR with 7.1.2 support
Changelogs for previous versions:
Version 2.4.0
Code:
- updated with latest Linux patches
- various fixes (including thermal management and network communication)
Version 2.3.0
Code:
I'm constantly working to provide a better kernel. This implies a lot of research, testing and stressing my eyes staring at code. I'm adding a lot of small fixes.
So, try to understand me if I don't always have time to report a changelog.
As always, you can check GitHub for a detailed changelog.
Version 2.2.1
Code:
Sorry if I didn't write down a changelog for the last releases, I've been quite busy.
Anyway: since version 2.1.6b there are a LOT of changes, performance, battery, stability... Just check it out (and check GitHub for a full changelog).
Version 2.1.6b
Code:
- updated busybox and sqlite3 binaries with more convenient versions
- changed optimizations, enabled safety features and possibly fixed f2fs cryptography
- getting ready for the Synapse restyling
- build the kernel uncompressed
The latter fix solves most lagging issues and noticeably improve performance over compressed version; I'll look into the kernel size issue soon!
Version 2.1.5
Code:
- ramdisk rebased over RR's one
- kernel size reduced
Version 2.1.4
Code:
- updated interactive governor with Samsung optimized version
- implemented the AMOLED flicker free patch
- updated ramdisk for both herolte and hero2lte to the one from latest LineageOS builds
- updated ramdisk to be compatible with SlimROM (untested)
- removed a few redundant tweaks
- fireactive it's on its way to debut, but still disabled because incomplete, sorry :(
Version 2.1.2
Code:
- init: added a few tweaks
- ramdisk: changes in sepolicy
- ramdisk: try to fool safetynet and fix wakelocks
- updated to DQBO kernel source
- fstab: reworked mount options
- fs: add exfat support
- fs: implement optimised and stable f2fs (from oneplus/QC8996_N)
- enabled Swap (I had the idea while looking into the OP3 sources)
Version 2.1.0
Code:
Many beta versions came before this one, and all of them had their list of fixes... I'll try to summarize:
- some configs were tweaked
- enabled init.d support
- Synapse support
- implemented elementalx
- various fixes
- faked Knox 0x0 and try to hide from SafetyNet
- switched back to cfq as default scheduler
- probably other stuff I can't remember now... I need to sleep ahahah
Version 1.2.4
Code:
- temporarily reverted to Linux 3.18.14 (and so fixed the video playback issue)
- updated mount options to reduce I/O overhead
- tweaked the kernel configuration to have better performance
- enabled additional compression algorithms and cryptography utilities
Version 1.2.3
Code:
- updated zen sched driver to version 1.1
- SELinux is now set to Permissive by default
Version 1.2.2
Code:
- now using zen as default I/O scheduler
- changed the default frequency range for the CPU
- updated to Linux 3.18.17 (still working to bring the latest patches)
- switched to a custom Makefile optimised for our architecture
Version 1.2.0
Code:
- overclock and underclock support for both CPU and GPU
- voltage control (see notes in the OP [B][**][/B])
- moved to Uber Toolchain 7.x (aarch64-linux-android-7.x)
- improved recovery installation script
Version 1.1.0
Code:
- First public release

[TUTORIAL] How to set up your phone with f2fs
1) First you have to install a compatible recovery. Recent TWRP releases can format and mount f2fs, but they don't handle a few installation scripts correcty. I recommend TWRP 3.0.2-4 by @lyapota which has the correct patches. You can find it here.
2) Then you have to backup all your data (internal storage will be wiped too, so make sure to copy ALL your files in the INTERNAL storage). So, any TWRP backup should be taken on external SD card.
3) After this, reboot into TWRP. From Wipe / Advanced Wipe check only /data, then select Change Filesystem and check f2fs. Do the same for /cache. At the moment I don't think there are ROMs that support f2fs on /system too (LineageOS, for example, forces ext4 and formats despite settings).
4) Reboot into recovery once again, so we're sure that it can mount everything.
5) At this point you're done. Flash your ROM of choice, this kernel, any GApps and whatever you want.
Reboot and profit!
ROMs supporting f2fs formatted /system will be listed here when available.

Awesome. Will this make oasp run better as there based on proper drivers etc? Can this improve the camera? Sorry for questions I have really messed with aosp on s7e yet

The idea is to have more customizations, features and overall a better user experience than the kernel the maintainers of our device provide. The changes I made are listed under features.

Yes. It's a simple .zip that just flashes the kernel (not rooting or anything, but maybe in a future I can upgrade to an aroma installer).

I just posted in another thread regarding use of your kernel
https://forum.xda-developers.com/s7...extended-rom-v3-1-t3559696/page4#post71203867
I had hoped that using your kernel would allow for full functionality of Magisk -- unfortunately it did not
I really think that since Magisk works well with Stock ROMs it has to do with repacking of the boot img
Hopefully you would be willing to touch base with @topjohnwu to work on obtaining full Magisk compatibility with AOSP Galaxy S7 Edge ROMs
Thanks for you work

wow! thanks so much was hoping for a custom kernel for AOSP! i hope you will consider adding undervolting and synapse support. Thanks for your efforts!

The next in my to-do list are underclock and overclock, followed by voltage control.

I flashed it right now on RR . and im impressed as its smooth af. Im not too sure about battery life , but i fully admit its improvement on performence . good job dev . keep it going

Warning: If you come from some other custom kernel or have any issues, you should dirty flash your ROM before flashing Oxygen Kernel to avoid problems.
Reflash ROM -> Flash Oxygen Kernel --> Flash Magisk if you want to root
If you are upgrading between Oxygen Kernel versions, just flash the kernel zip. Also uninstall or clean data of any kernel control app you're using.
Going back to stock: You can backup your boot.img with TWRP before flashing Oxygen Kernel and restore the backup whenever you want to revert.
1] This kernel removes forced encryption, if you face "encryption process failed" error upon reboot then you need to format /data. This is generally needed if you are installing this kernel on stock tw rom.
2] In OneUI Pie ROMs you may get a warning at boot saying "There's an internal problem with your device". You can safely ignore this warning and causes no harm. It's due to some mismatching KNOX/mobicore stuff. I'll fix it soon.

Thanks for the awesome work, my friend!
One question: how to enable the real frontal flash for G610M? Here I keep getting just that white screen (virtual flash).
Kernel is working fine, but frontal flash isn't.

If you're on stock rom then it should turn on the real flash. If on custom rom then kindly ask the dev to add support in rom

Try formating /data after flashing kernel

Loved your kernel :good:
Only bug I'm facing : Camera effects are not working (both front and back).
Thank you.

Camera effects working for Me, maybe dirty flash?

Does it work if u flash back stock kernel? Actually the kennel would not affect camera filters. Maybe check your rom for the act.

can i use this in 6.0?
sorry for stupid quesion . just asking. ty

Kernel Special Features:
Version Information
Status: Testing
Created 2019-09-04
Last Updated 2019-09-04

Tweaks part 1​
Cpu governor
this kernel come with many cpu governor hoewer i suggest to choose only :
interactive (default)
blu_active
ondemand
lolz_snappy
Intelliactive
The best governor for:
everyday usage (light) = interactive or smartax or smartax_eps
everyday usage (moderate) = interactive or ondemand or intelliactive
everyday usage (intensive) = blu_active or lolz_snappy
games = performance
music/video playback = intelliactive or smartax or smartax_eps
Note: some governor performs better when they are tweaked, at the of this post you will find a zip with some amazing profiles (IHMO).
==========================================================================================================
Cpu Hotplugs:
this kernel is shipped with AUTOSMP, Lazyplug, Bricked hotplug, blu_plug
there are many guides out there that explain their best use scenario
hoewer is suggest interactive with bricked hotplug for moderate usage
when you are using a hotplug is hightly suggested to enable cpu.notify_on_migrate
the sysf path is "/dev/cpuctl/cpu.notify_on_migrate" (0 = disabled) (1 =enabled)
==========================================================================================================
Cpu-boost driver:
This kernel come with 2 cpu input boost driver:
Caf cpu boost(enabled by defautl) and Sultan's cpu input boost
both are tweaked by default
Caf cpu boost has the ability to boost all online cpu to the max freq when an app is launched to reduce latency, to enable this option you need to change the parameter in
"/sys/module/fork/parameters/boost_when_app_is_launched" from "N" to "Y" (N = disabled) (Y = enabled)
IMPORTANT:
use only one at the same time
AUTOSMP and blu_plug have their own input boost so when you use one of them disable both caf and sultan's cpu boost
==========================================================================================================
Gpu governor:
I reccomend to stay with the default governor and enable adreno_idler if are wathing video or play music to reduce power consumption
==========================================================================================================
I/O scheduler
i suggest to stay with maple since is tweaked by default and perform better in any case scenario that i tested
==========================================================================================================
Ksm:
i writed some modification to the ksm driver, now it can be disabled or it can use differt tunables when screen is off
"ksm_thread_pages_to_scan_display_off" & "ksm_thread_sleep_millisecs_display_off"
which are equivalent to ksm_thread_pages_to_scan & ksm_thread_pages_to_scan but they are enabled when screen is off (so you should use more relaxed values)
syfs path for both values are "sys/kernel/mm/ksm"
if you want disable ksm whem screen is off the parameter can be found in "sys/module/ksm" (N = disabled) (Y = enabled)
==========================================================================================================
Misc:
when the screen is off the kernel can compact zones and drop cache in the RAM;
to enable this feature the sysf path is here "sys/module/compaction/enable_drop_cache" (N = disabled) (Y = enabled)
you can even modify the interval "sys/module/compaction/interval"
==========================================================================================================
Kcal settings:
I collected some kcal profiles to archive a better color reproduction those profiles can be found in zip at the end of the post
==========================================================================================================
Filesystem:
Our phone support both f2fs and ex4
Ext4 is suggested for system partition
F2fs for data and cache partions

Tweaks part 2​
I made a collection of the best governor settings; kcal profiles and the all kernel parameters mentioned in the upper post (that aren't avaible in any kernel manager by default)
if you are using elementalx you can directly insert the folder inside your memory and enjoy, if you are using any other kernel manager you can benefit anyway but you will need to apply manually those settings

i don't exactly know if it's kernel's problem...
device is taking more than 5-8 hrs to fully charged.
device shutdowns if charger is unplugged after 90%
I'm on Lineage OS 16 official rom

New version
Changelog:
1.Underclock cpu to 268Mhz
2.Underclock gpu to 100Mhz and idle to 27Mhz(is disabled by default so you need to enable it)
3.Set optimal value for cpu input boost(is disabled by default so you need to enable it)
4.Add adreno idler
5.Disable some unnecessary debugs

Probably a logcat would be useful...
anyway on my phone i don't have problem with charge mode( i NOT touched charger stuff on my kernel)

noob question, how do u enable those features (hotplugs, cpu input boost, etc..) that is disabled by default? cant see them in kernel manager im using FK's

New version
Changelog:
1.Merged last Lineageos kernel commits
2.Dropped 02 in favor of Os
3.Dropped f2fs support
This version like the others is not backward compatible

Hi linckandrea,
First, thank you for your great work, it is great to see our old moto x 2014 is still alive
Do you think it is a good idea to flash your lastest kernel for android 9.0 with the lastest version of Lineage OS 16 for victara? If not, I would like to merge your kernel source for android 9.0 with the one from Lineage OS 16 and built it. I am going to follow this reference https://forum.xda-developers.com/android/software-hacking/reference-how-to-compile-android-kernel-t3627297 Is this procedure ok? or Am I missing some intermediate step?

hi you can flash the latest version for pie with the latest version of los16 without problems

Download version for Android 10 but gives error in twrp when flashing, error 1 wrong Android version even though I'm on Android 10

BIG UPDATE !!!
Changelog:
1.Merged last Lineageos kernel commits
2.Added wake gestures ( D2W, S2W, S2S )
3.Reworked lazyplug hotplug (all cores are now online when screen is on)
4.Added bricked and AutoSMP hotplug
5.Tweak intelliactive governor to not boost when screen is off
6.Added zzmoove cpu governor
7.Simple gpu algorithm by faux
8.Add some tweaks to ksm by me
Now you can disable it when screen is off in order to allow the device to go in deep sleep much easier
you can also set
"ksm_thread_pages_to_scan_display_off" & "ksm_thread_sleep_millisecs_display_off"
which are equivalent to ksm_thread_pages_to_scan & ksm_thread_pages_to_scan but they are enabled when screen is off (so you should use more relaxed values)
"ksm_thread_pages_to_scan_display_off" & "ksm_thread_sleep_millisecs_display_off" tunables can be found in "sys/kernel/mm/ksm"
if you want to disable ksm when screen is off, the parameter can be found "sys/module/ksm" , parameters allowed are "Y" (to enable) and "N" (to disable)

Hi, all, have this kernel in Android Q support for Texas Instruments audio chp? in other releases of android more old, yes.

Hey, I've been using your kernel for ~half a year now and it's great.
I installed it, the Smartpack Kernel Manager and Magisk (for root for the manager).
It's awesome, K-Lapse is much nicer than Live Display, GPay didn't break (yay), I could tweak a few minor things that always bugged me, and through undervolting (and -clocking) I could even mitigate (to almost eliminate) the battery-shutdown-issue!
The only thing I was missing, was the "wave to preview notifications" feature from Ambient Display. But a few weeks after I installed the kernel, it started working again. (Im 90% sure I didn't update LOS, it just suddenly started working.) I have no idea why, but I didn't dare to update LOS or Magisk since for fear it might break again, maybe you have any
Now that LOS 18.1 is out, I was wondering - if this kernel doesn't work for 18.1 (which I assume it won't?) - are you planning to update it to do work? It's really amazing how much more useful live I was able to get out of the phone by tweaking the kernel.
Thanks for your work.
