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.

How to Flash:
1. Download the kernel and place it into your phone storage
2. Reboot into recovery
3. Install the kernel
4. (optional) Wipe Dalvik/ART Cache and Cache partitions
5. Reboot and enjoy!
You need ROM's default kernel before flashing this as this kernel uses Anykernel2 by @osm0sis (huge thanks to him). Make sure you have it otherwise clean flash the kernel with the rom to avoid any issues.(At least dirty flash rom+kernel)

I did at one point and then I clean flashed it with Viper OS to see if the same problem was produced. Sure enough... More specifically videos through my messenger app would not play and the view finder screen in the camera app wouldn't work.

overclocking
hi do you think this kernel source code can be modified to increase the CPU and GPU overclock?

[EOL][KERNEL][7.X][i9300] Koffee

Koffee is the first kernel which has fixes and backports, allowing Magisk running properly.
Only for Nougat(Android 7.x) ROM's!
Based on latest Boeffla, tweaked and extended by patches & backports.
Main idea of kernel is stability, extra features and compatibility with recent apps.
Configurable via Boeffla Config V2, Synapse or Kernel Adiutor
Recomended to use Magisk with this kernel, but other SU implementations also compatible.
This kernel is good choice for ResurrectionRemix N.
Code:
/* #include <xda/disclaimer.h>
*
* Your phone's warranty is now void.
* This is a custom kernel developed by me, A$teroid
* You are flashing this on your S3 at your own peril.
* I am not responsible for hard bricks, damages to SD Cards, thermonuclear war,
* or you getting fired because the alarm app failed.
* I would definitely help you out if you are stuck somewhere, provided that you give
* me clear details of the mishap.
* Don't ask for ETA's cause there is a thing called "LIFE" outside XDA.
*/
Please check for few times that your trouble caused by Koffee and nothing else.
I do NOT accept ANY bugreports if you're:
1. do overclock or undervolt
2. use non-default kernel settings
3. doesn't provide me kernel / system logs if it crashed
4. doesn't provide me info about installed ROM, mods, root-utilizing apps
5. have installed Xposed
6. have installed tweaks
Features:
Boeffla Kernel features
Backported Mount Namespace from 3.8, allows hiding root via Magisk and pass SafetyNet
Fix (v3) for sleep issues when Magisk installed
SDCardFS
@forkbomb444's HWC out-of-the-box
Allowed much lower display brightness(with addon)
Compatibility with experimental LineageOS
Doze Helper - turn on Doze immediatelly after screen off
Pyramid - new cpufreq and hotplug governor
zCache
FRandom - fast pseudorandom number generator
FQ_Codel network packet scheduler backported from 3.5
TCP Fast Open (client-side, ported from Linux 3.6), enabled by default
TTL mangling support
SECCOMP - Secure computation for untrusted bytecode (used, ex., by mediaserver, Google Chrome)
Support for I/O accounting (for iotop)
Sparse Memory model
Enabled ThumbEE CPU extension
----
Read also:
Tweaked page-writeback for better responsiveness. You cannot change vm.dirty{ratio/bytes} values.
zRam configuration is disabled for stability reasons but zRam is present
/system is write protected! Use system-rw-access.zip Magisk module to disable protection if you really need this!
More additional fixes which not exist in other kernels
Various kernel tweaks, config changes & internal improvements
Reduced wakelocks
Reduced debugging code
Boeffla Sound enabled by default
----
Pyramid
tunables:
mc_pseudocluster, mc_pseudocluster_freq:
allow to work on max frequency up to 2 cores and limit it to mc_pseudocluster_freq value when > 2 cores online
Enabled by default.
mc_eco_auto, mc_auto_factor:
when enabled and pseudocluster are disabled, relative maximal frequency will be calculated usind number online cores and mc_auto_factor.
Greater factor values will reduce max frequency.
Disabled by default.
mc_eco_step{1-3}:
when pseudocluster and eco_auto is disabled, old pyramid's behavior will be enabled.
Using this three tunables you can define frecuency at each next cpu core.
screenoff_limit, screenoff_freq, screenoff_max_cpus_online:
when screenoff_limit is enabled, maximal frequency will be reduced to screenoff_freq value and maximal allowed cpu cores will be limited to screenoff_max_cpus_online.
Disabled by default.
min_cpus_online:
you can set minimum of cpu cores allowed to be enabled when screen is on
max_cpus_online:
you can set maximum of cpu cores allowed to be enabled
----
TCP Fast Open
you can use TFO in Chrome browser, just turn it on via chrome://flags. Also Chrome can be used as system WebView provider via Developer settings.
----
Addons:
1. Svelte(low-ram, Magisk)
Enables Project Svelte to increase performance on low ram devices. Also tweaked for responsiveness.
2. Lower Brightness - use, if you prefer darker screen or want to save battery (Magisk) Only for Koffee 78+!
3. SDCardFS (Magisk) - use sdcardfs instead of slower fuse emulating. Reduces overhead on internal and external storage access
4. I9300XXUGOK1 modem (zip for TWRP)
5. I9300XXUGPE1 bootloader (for Odin)
6. System Read-Write access. Install this if you really need write access to the /system.

just download latest zip & flash via twrp

Nice, will give it a go, the only downside about my giving this a try is that I'm using SuperSU. Otherwise I am on RR N
Thanks

Spectre
Does Spectre need to be mitigated by the kernel or the ROM?

can I dirty flash it over the elite-boeffla-kernel-6.0.0.2 or do I have to install RR N again and then flash Koffee-kernel?

No: kernel based on boeffla and on old smdk4412 base.
Kernel in experimental lineage 14.1 based on n7100 kernel sources and has experimental HWC implementation. I'll rebase Koffee to the new codebase in future, but now this code is not enough stable.
And all other custom kernels is NOT suitable with experimental Lineage.

Attack variants are different to processor variants.
The A9 is vulnerable to Spectre (attack variants 1 and 2) but not to Meltdown (attack variant 3).

The best kernel out there! Thank you so much! Now I can pass safetynet!
Best regards!

Hey brother @A$teroid I wanted to ask that what if i wanted to use superSU with this kernel ??
Look , First I have installed Resurrection Remix
then , I have uninstalled magisk and installed superSU.zip
So , Can I install your kernel now ??
I wanted to use your kernel as well as superSU !
Help

You can use Koffee with any Nougat ROM and with (or without) any SU implementation.
I use Koffee with RR + Magisk.

[KERNEL][Z017/Z012][TREBLE][P5] Advanced Kernel for Custom ROMs

Code:
#include
/*
* I am not responsible for bricked devices, dead SD cards, thermonuclear
* war, or the current economic crisis caused by you following these
* directions. YOU are choosing to make these modificiations, and
* if you point your finger at me for messing up your device, I will
* laugh at you.
*/
This kernel should be compatible to all up to date Pie/Oreo custom ROMs. Its goal is to further improve battery life and to offer as many features as possible while maintaining perfect stability. All battery tweaks are toggleable so you can decide whether you prefer performance or battery life.
Every release will be tested with the latest LineageOS 16.0 build before release.
Compatibility to other custom ROMs is very likely but cannot be guaranteed.
Advanced Kernel for Oreo is now discontinued. The non-treble Pie version should work fine with Oreo ROMs.
Features
Built with bleeding edge GCC 10.0.0 toolchain, optimized for Cortex-A53
Linux 3.18.140, CAF Tag LA.UM.7.6.r1-05500-89xx.0
Treble ROM support.
Spectrum
WireGuard VPN
KCAL v2 color control

Adreno idler
Adreno boost
Slimbus OC
Fingerprint boost
State notifier
Boeffla wakelock blocker
CPU wake boost
Vibration intensity control
Force fast charge to enforce maximum charging speed on any charger. (Use at your own risk! Disabled by default.)
Qnovo driver for better charging temperatures
Powersuspend
Toggleable touchboost
Powersaving work queue by default
Tuned interactive governor
Additional lower frequencies: 307MHz and 480MHz
Additional overclocking frequencies: 2208MHz and 2150MHz - Only selectable in OC version.
Disabled CRC check for up to 30% faster I/O, toggleable
Fsync switch
Improved zram with lz4 compression
Native CIFS and BTRFS filesystem support
Support for SMB2 and SMB3
SdFat for FAT and exFAT support
Support for rtl8812au and rtl8814au usb wifi adapters.
CPU governors: relaxed, chill, electron, elementalx, impulse, zzmoove, alucard, darkness, nightmare, yankactive, intelliactive, blu_active, interactive, conservative, ondemand, powersave, performance, userspace
Hotplug governors: alucard_hotplug, thunderplug, blu_plug, msm_hotplug, intelli_plug, lazyplug, autosmp, AiO_hotplug (Pie only)
I/O schedulers: noop, deadline, cfq, bfq, sio, fiops, zen, maple
TCP congestion algorithms: westwood, reno, bic, cubic, highspeed, htcp, vegas, veno, scalable, lp, yeah, illinois
Countless additional improvements
Overclocking
With every version of Advanced Kernel two files are released: One with overclocking support and one without. Be aware that overclocking may physically damage your phone! If you still want to use it, download and install the kernel zip from the "Overclocking" subfolder. The default zip from the main folder doesn't allow overclocking and is "safe".
The overclocked kernel will first boot with 2.2GHz, then the maximum frequency is lowered by the active spectrum profile. To enable overclocking after booting you have to use a kernel manager app to select a higher maximum cpu frequency. The tradeoff is that higher frequencies also come with higher CPU-voltages so your battery level will drop faster while OC frequencies are in use.
Force fast charge:
Available on the OC and non-OC kernel. This feature overrides the detected charging current with the maximum possible current for the Zenfone 3 (1910ma) so that every charger is fully utilized. Please be especially careful when using this feature as possible safety measures are disabled! It's disabled by default and can be enabled by enabling "USB fastcharge" at KernelAdiutor's "Battery" section or in EX Kernel Manager under "Miscellaneous".
Installation
Simply flash the provided zip file via TWRP over your custom ROM installation. No need to wipe anything!
Before flashing you may want to backup the "Boot" partition. Restore it to revert any changes.
Flashing a ROM will overwrite this kernel: You'll have to flash the kernel zip again after updating your ROM.
In order to use all of the features you'll need some additional apps and root:
Spectrum: Offers some easily selectable profiles. These are still WIP and in no way comprehensive!
A kernel manager like EX Kernel Manager (paid) or Kernel Adiutor (free).
Spectrum profiles
Battery: Very battery friendly profile. It sacrifices performance for battery life.
Balanced: As close to stock as possible with only minor tweaks.
Performance: Tuned for CPU performance.
Gaming: Everything always runs as fast as possible. Burns away your battery!
Reporting issues
Before reporting an issue please check that it only occurs when having this kernel installed. Otherwise it may be an issue with the ROM.
The above also applies the other way around: Don't report issues to the maintainer of a ROM unless they also occur without this kernel.
Be aware that performance issues are very likey related to your personal settings. Don't blame me for your decision to run only one core at 307 MHz
Always use the latest Advanced Kernel release with the latest build of you ROM of choice. If the kernel is much newer than the ROM or the other way around weird issues may arise.
Download
All zip files support both the ZE520KL and the ZE552KL.
The treble version is only compatible to treble ROMs using APD as the vendor partition.
The non-treble version is compatible to non-treble Pie ROMs and SHOULD be compatible to Oreo ROMs too.
Flashing the wrong version won't harm your device but will prevent your ROM from booting! This can be easily fixed by flashing the right version or re-flashing your ROM.

Kernel Modules
Here you'll find a description of every currently available kernel module for Advanced Kernel for Pie. (The oreo version is not currently supported.)
Kernel modules are drivers that can be loaded into the kernel in order to use hardware that would otherwise not work. A kernel module comes as a .ko-file and is only fully compatible to the kernel version it was released for. Modules can be loaded by executing "insmod [module].ko" within a terminal as root on the phone.
Every new Advanced Kernel release will come with a new version of all available modules.
The modules can be downloaded from the "Kernel Modules" subfolder (here).
Available modules:
RTL88XXau/RTL8814au
The rtl88XXau module allows you to use usb wifi adapters with the rtl8812au or rtl8814au chipset with your phone.
This driver was forked from aircrack-ng and features monitor mode and frame injection. TX-power can be tweaked too.
Check the readme on github (still WIP) on how to use it: https://github.com/Planet-X/rtl8812au/blob/v5.3.4/README.md
I only ported the driver to this kernel. Check the module's sources for credits: https://github.com/Planet-X/rtl8812au/tree/v5.3.4

I feel like my device is lagging. Even when I set everything to Performance.

So many features...

It's all about finding the right settings
Just take your time to find them - I do admit that default settings are very conservative/battery friendly...
However I can assure you that this kernel can be just as fast or even faster than stock kernel. It's actually based on it so with exact stock settings you should get at least stock performance. The real problem is just tuning all these features which is why my spectrum profiles are still very basic ... too many variables take time for testing.
The next kernel version will move the current "Balance" profile to "Battery" and change "Balance" to be very stock-like. The current "Balance" and especially "Battery" profiles may be a little too extreme... :silly:

The system wide mic gain is working perfectly for whatsapp voice messages,but unfortunately it is not applied to video recording it seems... I tested it with Lineage Camera App and Whatsapp camera
Great, that I dont have to fiddle around with mixer_paths.xml, but can you adjust the kernel to let the mic gaion also apply to the video recordings? Many thanks!

Well, i guess i Flash your new Rom Update and kernel and test it again
Maybe the videos are Sounding low volume to me, because they need more Gain Boost than pure sound records?
The slider for the kernel is raising the gain equally for all inputs in general, but maybe the video recording gain is less sensitive then pure volume.

It somehow is and isn't: Currently there should be no problems and it should work fine.
I can't guarantee, however, that it'll stay this way in the future. Just be aware that issues may arise due to kernel incompatibility.
I can only assure that my kernel is fully compatible to LOS 15.1. With every LineageOS update a new advanced kernel version will be released. As Xenon kernel improvements get merged into LOS and vice versa it should stay compatible but, again, I can't guarantee it...

To go back to the stock kernel you simply have to reflash the LOS zip file in twrp, then reboot. You don't need to wipe any partitions.

0.3 version is out. Read the OP.

Advanced Kernel V0.4
Advanced Kernel V0.4 has arrived.
It's just a minor update to accompany the release of LineageOS build 2018-03-25.
Changelog:
Updated kernel to Linux 3.18.102.

Advanced Kernel V0.5
Advanced Kernel V0.5 is now available.
Changes:
Added vibration intensity control.
Added fsync switch.
Imported a load of other improvements.
Updated compiler to Linaro GCC 7.3.1.
Updated kernel to CAF Tag LA.UM.6.6.r1-07200-89xx.0.

*
* 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. */
1. What is RedLine Kernel?

If you ever flash Magisk before, it got deleted. Reflash magisk or keep unrooted, that's up to you
Reboot
If you face the 'there is a problem with your device' (AOSP GSI), simply ignore it
5. Bugs
You tell me If you want to report, please send me last_kmsg from /proc and logcat when doing the bug. Syslog is helpful too.
6. FAQ
A: Does my data will going to deleted when installing this kernel?
B: NO! The installer script is just replacing boot and dtbo partition, NOT DATA PARTITION. So data will safe.
A: Keep getting bootloop or infinity boot (enter the screen and then goes back to boot animation)!
B: Do you flash in GSI? What GSI you use? And you sure you flash this after Android 10 update, so the Q vendor is installed, not P?
A: You f*cking fake!! This is broken kernel!!
B: Dude, I tested this kernel my self! And it works properly. You want proof? Go to Post 3!!
A: Great! How I can help you? By donating?
B: See number 7 below
6. Screenshots
See Post 3
7. Donate
If you feel this kernel is helpful, and want to help me build by donating, here is the answer : Don't donate to me, donate to other people that more need donation. I'm not being rude, or don't want to be helped, or whatever. This kernel is builded in my free time, so I don't do this for job, but just my hobby
8. Source
Kernel : https://github.com/RedLine-Project/RedLine_j4ltejx
Defconfig: redline_defconfig
GCC: Google GCC 4.9, branch ndk-release-r17
My source is freely used for anyone. You can fork it, clone it, even build it without my permission. But, if you want to rebuild kernel, add other features, and share to somewhere, please add my credit! Atleast my XDA username, 'source forked from RedLine', or anything! It will be very appreciated

Great work bro. I am still waiting for an overclocked kernel for a51 tbh but anyways great work. Also you asked me about the dtbo support in ofox , was that to make this work with ofox?

I'm not sure. At first I just flashing dtb to dtbo partition, with maybe expecting any different, but I think it is little bit useful.
But still can't install in twrp 3.2, since it Android O based (no system_root), so myb will edit the script.
And for A51, I already send query for samsung to release OneUI 2.5 / U4 source, but still no respond. If I develop now, it may useless because there is a chance will cause conflict when importing U4 source in future. And Exynos 9610 is something quite new to me, so need to learn kmsg, log, and dts.
Btw thanks

the link doesn't open bro

Fixed. My website is under deletion, and I upload release in GitHub. Check the new link.

will it work on the J5 Prime? since it has the same chipset (exynos 7570) and I would like to try it.

Hi!
Yes, because it's discontinued. Even the source link is dead too. I'll change the status to discontinued in thread.
But I make new kernel: https://t.me/SamsungGalaxyJ4/13629. However it's still in testing phase, but will released if I have time.
Thanks!

Looks like awesome work! I'm excited to see the performance on others tab S7 devices! Any plans to support SM-T970 tab S7+ wifi?

Kernel nice ..... could use help with twrp

Does this overwrite the entire operating system? Does it add some tweaks to the current operating system? I'm a little confused about what flashing this does. And since we don't have TWRP for this device I don't want to mess up my current set up. Thanks.

Latest release boots on T875BUK2. Device seems to be fine, 4G also works.
Edit: Well, apart from the kernel panic whenever the device wakes up from sleep. Since its not for T875, I guess trying it isnt a very bright idea then..

Why A11. Mostly every 1 on A12.

If you don't know what flashing a custom kernel will do to your device, it as well not be important at all for you to flash it. Just use your device stock.

I don't know. It's why I asked the question as to what this does? Your response didn't really address my question, though I appreciate the response. This is only a kernel and not the full rom? What is the advantage to flashing this compared to root with magisk?

RIP. I’ll play the tiny violin for you while you put it in download mode via the key combo and restore it with Odin and the firmware files from Sammobile

This kernel is a monster!! Thanks
