[KERNEL] [ROOT][MM | N] [SM-G920P] [19-Jan-2019] SkyHigh Kernel (Port) [v7.30]

SkyHigh Kernel -- Ported to SM-G920P (Sprint Galaxy S6).
This is, unquestionably, the most up to date kernel for the S6 devices. That includes upstream kernel (vanilla) additions bringing it to the latest (3.10.108) publicly released. This project started as a port of the SkyHigh kernel, originally by @UpInTheAir, to the G920P kernel. this kernel, however, has a great deal of further enhancements and optimizations relevant to Sprint Galaxy S6 device. The boot image build is not embedded in the kernel sources, as it is in the original, rather is an automated build in a separate project.
Donations:
I do accept donations, you are by no means required to, it just invigorates me to do more stuff in the kernel . With that said, apparently some devices fail to show the donation link next to posts, so you can click here to donate.

Thread Rules
This thread is for the development and furtherance of kernel features. There are a handful of rules to this development forum with which you must comply or you'll likely get ignored:
This is not a general Q&A thread, it is a development thread. Please use the Q&A thread for general questions.
Do not ask @UpInTheAir for support, this port is not one he maintains;
Do not post anything without first searching the forums, if your issue has been discussed before, you will get no response;
Do post anything relevant to the development and furtherance of the kernel. Please use the Q&A forums for questions and general discussions.

Many descriptions are in the Synapse Application. If you require more info, follow the thread rules above.
Flash Descriptions:
Note that there are two downloads: an Update and Full boot image.
The Updates are for currently running ROMs. If you just want to update the kernel and related utilities (startup scripts, busybox) and have no other modifications to your boot image, download and install the Update version. The Update injects the kernel update into your existing boot image, it does not touch the remainder of the boot image. The update is also useful in cases when folks dirty flash ROMs just to change features or have older ROMs and want to try the latest kernel, therefore do not have the ROM flash install the kernel at all. The issue with that is the ROM flashes generally do not know to keep the kernel modules, so those get deleted. This updater will reinstall those as well. In brief, it is an update of the kernel and its important files only, it does not root the ROM as does the full version.
The Full boot image flash is a complete boot image, which is the normal flash. However, some ROMs install other systems (e.g., my hotspot fixes) which also modify the boot image, specifically files in the ramdisk. For initial, or clean installs of this kernel, download and install the Full flash. It will also root the ROM for you if not already rooted (SuperSU is installed). You will want to add other boot image modifying flashes after that (though there are not that many flashes that actually modify the boot image).
The general rule is this: if you are installing this kernel on a ROM and have never installed this kernel, use the full version. If you are already running tdhite SkyHigh on a ROM, download and flash the Update version of the kernel.

The sky-high module now supports calling a script every time the cortex tuning script executes (appx. every five seconds). Just place a valid script in "/sdcard/SkyHigh/scripts/user.sh" and that will get called by the /system/xbin/cortexbrain-tune.sh script each time it executes in the background. Be very careful, the user.sh script has full root access!

Many new optimizations (even more than beta 4.99b).
Roots the phone with Magisk v12.0
Places the MagiskManager 4.3.3 in /sdcard/MagiskManager-4.3.3.apk for easy installation after flashing the kernel. Just open your file browser and click on the file, then select install.
If you are SuperSU or Magisk v13 rooted, you should uninstall your root manager app and unroot. The kernel flash will re-root you. If you are Magisk v12.0 rooted, no work needed, just flash the kernel and profit!
Both Magisk and SuperSU provide for uninstall applications. If you don't know how to do that, read the SuperSU or Magisk pages. It is not difficult -- basically for SuperSU, you need to: 1) delete the SuperSU app while in Android ROM; 2) boot into TWRP (recovery); 3) delete /data/su.img and /data/stock_boot_*.img; and finally 3) flash this kernel, but not before). For Mgisk, just use the Uninstaller module.
Note, you need to update the MagiskManager app after booting up. The app, as installed by the Magisk installer, will tell you to update from the App store -- your phone is rooted, you just need to update the app. The app installer (apk) is placed by this kernel flash in /sdcard/MagiskManager-4.3.3.apk for easy access (see above).
Remember that when you try to install the manager app, using your file manager, be sure you have "Unknown Sources" checked on in Settings -> Lock Screen And Security.
After you install the Magisk Manager, Synapse will obviously request root access, grant it 'forever' so it will work on boot thereafter. On first time running, Synapse might (rarely) fail and quit or complain there is no root or uci access. To fix that, just open your 'Recents' list and swipe away Synapse. Restart it and it should now have root and work properly. Setup the kernel as you like from there.
The kernel startup scripts are now part of a Magisk module. If you reinstall Magisk by your self, it may clobber that module. I'll post the zip for that if folks have trouble. DO NOT DELETE THE SKYHIGH MODULE in the MagiskManager app.

may i ask about the battery life of this kernel?
is there any known issue list that i should read before flashing this?
thank you very much for this first kernel for our G920P.

Port of the SkyHigh Kernel, originally created by @UpInTheAir, to SM-G920P (Sprint Galaxy S6).
This port is rebase of the SkyHigh kernel commits onto the G920P kernel base sources, as well as other and modifications relevant to Sprint Galaxy S6 device. The boot image build is not embedded in the kernel sources, as it is in the original, rather is an automated build in a separate project.

NOTE: This Thread is Under Construction and will be Completed by End of Evening, 04/03/2016, not before. Please honor good 'dev thread' etiquette and do not post anything until you 1) have the kernel; 2) have installed it; and 3) have a problem or feature request related to it.
This is a healthy effort to both create the port and build the content in this thread so give fair time as we all have important life duties outside XDA. Also, this is not a general Q&A thread. That is why we have multiple forums, please use the Q&A thread for general questions. That forum will autogenerate soon enough.
Thread Rules
This thread is for the development and furtherance of kernel features. There are three rules to this development forum with you must comply:
Do not ask @UpInTheAir for support, this port is not one he maintains;
Do not post anything without first searching the forums, if your issue has been discussed before, you will get no response;
Do post anything relevant to the development and furtherance of the kernel. Please use the Q&A forums for questions and general discussions.

Please use the q&a thread for questions, as stated in the OP, in the future. That said, a kernel has nothing to do with menus.

I flashed this on my S6 and man I sure miss getting to use this kernel and synapse on my Sprint Note 5 but at @UpInTheAir is taking some time off till the end of April until he updates it to work on 6.0.1. I have a couple of java string errors when it comes to the wakelock controls but that might be due to the issue I'm having with the stock ROM. For some reason after I ODINed the 6.0.1 firmware on my phone won't activate and it says it is on Samsung Network but hotspot and everything else works so I wasn't going to mess with it. Great job with the kernel. I cannot wait till my note has it again.

Love this kernel as it doesn't give you that warning "kernel not seandroid enforcing" but I still benchmark slower than stock even with everything set to performance. I don't understand!
Any feedback would be greatly appreciated! Thank you!
Eric

For some reason my phone won't boot up with this kernel :/

my S6 didnt bootup after flashing TWRP 3.0.1-0 actually
i had to use the old TWRP 3.0.0-1 and flashed this kernel after, and it works.

Phone still won't boot up! -__- but now it gets stuck at the "Sprint LTE Plus" splash screen (instead of the Samsung splash screen).

I honestly don't know how to help you. I've asked for logs, rom info yet get nothing. How long did you wait for boot? OP says can take a while. You cannot send a logcat?
Seriously, I'd love to help, but it takes more info when one phone out of many, many others that work fine has an issue. There is clearly something about your rom or apps or whatever, but I have nothing to go on to help you.

OK so I feel like an idiot bro... I didn't know that your kernel script wiped cache/dalvik cache lmao -__-
THAT'S why it was taking so long to boot. Sorry bro! -__- Anyways this thing is smooth as hell!

Nevermind... Had to uninstall this kernel. My phone kept turning off & rebooting itself. No problems what-so-ever with the stock kernel. This kernel was causing some major hiccups with my phone.

[KEXEC] [ARM64] Kexec-Hardboot Patch

Note:
Kernel Developers: I would like to ask you to merge this patch to your kernels, because it is essential part of MultiROM (MR) - it allows MR to boot any kernel without changing the boot partition. I realize that it is no small request, but the patch is not big, touches relatively stable parts of kernel and should not cause any problems outside its intended function.
The Patch:
You'll need to cherry pick a total of 5 commits (if anyone feels like squashing them to help me out, feel free to link me to it).
Cherry-pick against: http://github.com/multirom-nexus6p/android_kernel_huawei_angler.git on the branch 'mm2'.

# CONFIG_ATAGS_PROC is not set # Prevents potential atags related discrepancies, this must be either removed or commented out
CONFIG_PROC_DEVICETREE=y # Allows us to read out the kernel config, and tell that the kernel has all the necessary configs enabled (read out from /proc/config.gz)

Introduction
As of July 11th, 2018, this kernel has been discontinued as I have sold the device. Since I don't recommend using a kernel that is not constantly updating, I suggest looking at RenderZenith if you are on OxygenOS or Singularity if you are on a custom ROM.
Hello everyone, this is my personal kernel for the OnePlus 5. While I am not a super star kernel developer, I do know my way around it. My philosophy on kernels is pretty simple:
Follow stable Linux always. Updates will be delivered within 24 hours of their release to kernel.org.
Stable kernel rules work best (only add small things when possible).
Security and stability are paramount. Vulnerabilities are patched as soon as they are disclosed.
Features will be added only as needed (I have a list of things in the FAQ I will NOT add, even if requested).
Hopefully you enjoy
Important thread information!
I refuse to acknowledge/respond to bug reports that do not include clear steps to reproduce, a logcat, and a console ramoops (if random rebooting) or a dmesg (any other issues). Follow this guide to do this.
Keep things civil, I do NOT tolerate flaming of any kind.
OT is allowed.
Features
NOTE: This list fluctuates with versions, it will not always been 100% up to date
Here are the major features of the kernel (feel free to explore Github)
Up to date with OOS (5.1.3 and Open Beta 12)
Custom branch compatible with most 8.1.0 ROMs (see below)
Up to date with the latest stable Linux version (4.4.140)
Up to date with the latest CAF tag for Oreo (LA.UM.6.2.r1-09300-sdm660.0)
Mainline patches from Linux, focusing on bug fixes/security
Mainline CFQ scheduler improvements
Kernel hardening from CopperheadOS
Several subsystems converted to use power efficient workqueues
The following user facing features:
Accidental touch protection on hardware keys
Backlight dimmer
KCAL color control
Maple I/O scheduler
Sweep2sleep
Sound control
Wakelock control
Latest WireGuard snapshot (0.0.20180708)
Westwood as the default TCP algorithm
Built with a self compiled Clang 7.0 toolchain with a local initialization sanitizer (build script here, previously built with the latest Google Clang 6.0 toolchain here)
Hides bootloader unlock from SafetyNet (can still fail through other means)
Disables dm-verity
Does NOT modify decryption status
Flashed with AnyKernel2 (thanks to @osm0sis)
Downloads
Primary: https://github.com/nathanchance/op5/releases
NOTE: The newer builds of 3.x and 4.x are unified! The zip will dynamically detect if you are on OxygenOS or a custom ROM and flash the correct kernel image.
NOTE #2: 3.x is for OOS 5.x 8.0, 4.x is for OOS 5.x 8.1
Installation
Through TWRP:
If you are on stock:
If you are on the stock kernel: flash the kernel zip and reboot
If you are on a custom kernel: flash the stock boot image matching your build number, flash the kernel zip, and reboot. I would also recommend dirty flashing the latest OOS zip as well.
If you are on a custom ROM:
If you are on the kernel that came with your ROM: flash the kernel zip and reboot
If you are on a custom kernel: dirty flash your ROM zip, flash the kernel zip, and reboot
Upgrading from one Flash version to the other:
Just flash the kernel zip and reboot
Through Franco Kernel Manager (requires root):
Getting back to stock if necessary (only needed if coming from another kernel):
Grab the latest stock boot image from the OTA zip.
Click on "Manual flasher", select the boot image, and select "Just Flash".
Reinstall Magisk through Magisk Manager (Install -> Direct Install).
If on stock or upgrading from another Flash release:
Download the zip (and optionally, the md5) from the link above
Tap on "Manual flasher"
Navigate to Download
Tap on the zip, select Auto-flash, and choose one of the options.
Reboot and enjoy!

Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably, I'm not going to fix the issue.
1.2 Q: What ROMs are compatible with the custom builds?
1.2 A: As of March 14th, 2018, I have confirmed the following ROMs are 100% compatible with Flash:
LineageOS
Dirty Unicorns
Codename: Phoenix
GZOSP/Validus
OmniROM
AICP
If you are using a ROM with no issues, let me know and I'll add it here! If you are having issues, following the above steps and I'll attempt to fix whatever incompatibility there is. If I can't do it without breaking LineageOS/Dirty Unicorns, you're out of luck.
1.3 Q: Can you add xyz feature?
1.3 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration. I will NOT add the following:
Overclocking or underclocking of CPU or GPU
Undervolting
Any governors other than interactive
Any schedulers other than cfq and maple
Anything that compromises performance
1.4 Q: How do I control the kernel?
1.4 A: I want to be very clear: the kernel does NOT need to be tuned to be useful. Most of the improvements are under the hood and don't require any user intervention to take advantage of them. In fact, if you don't know what you are doing, you could degrade the experience.
To control the user visible features of the kernel listed above, I recommend using either @franciscofranco's Kernel Manager for Franco Kernel (which has Flash Kernel support for downloading and automatically flashing the latest kernel zip along with some nice, user friendly ways for tuning the kernel) or @flar2's EX Kernel Manager.
1.5 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
1.5 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.
1.6 Q: I am not getting notifications on OOS, what is the cause?
1.6 A: This could be for a couple of reasons. If you haven't already, disable advanced optimizations in Settings > Battery > Battery optimization > Three menu dots. Another reason may be that I ship a compiled Wi-Fi module. I do this for two reasons: I want to have the latest fixes and I enable CONFIG_MODULE_SIG, which checks the signature of a module before loading it for security reasons. This could introduce some incompatibility with OOS, which is something I have no control over.
Thanks to:
The various other developers for their patches (specifically @zx2c4 for WireGuard and @joshuous for fixing the notification delay on Wi-Fi)
@osm0sis for AnyKernel2
@franciscofranco for adding Flash Kernel support to Kernel Manager for Franco Kernel
@adinkwok for being a bro
@phantom146 for the thread banner
All of you guys for viewing the thread
A note about donations
Quite a few people have asked to donate to me in the past and I have turned them down. I am not in this for the money, this is my hobby, something I truly enjoy. If you truly want to donate to something (it is not expected in the slightest), I recommend an entity like the Open Source Initiative, the Free Software Foundation, XDA, or any one of the people I have thanked in the OP. Additionally, you are free to copy any and all of my work; the only thing I request is that you not ask for donations as well (though I can't really enforce this lol). Thank you.

Some initial notes:
1. I have been working on this non-stop since I got the phone yesterday; it's been very stable as I have not made any drastic changes.
2. I have included a few normal features; I am open to additional suggestions (though please read the entire OP before doing so).
3. If you flash the custom version. please let me know if it works without issue so I can add it to the list. If it doesn't, please follow the bug reporting policy in the OP.
I have been up for almost 24 hours at this point so I hope I didn't miss anything but I plan on addressing any issues tomorrow/Sunday if any come up! I do also encourage you to participate in beta testing via Telegram, especially with all the custom ROMs.

Awesome work as usual @The Flash - Running perfectly on DU!

[NEW][Kernel] Entangled Kernel V1.0 [Alpha][X3][SscSPs]

Hey people,
I am glad to introduce my new Kernel to you guys,
Entangled Kernel​
Currently, I have not added any extra feature, except that you can use your phone as a USB keyboard and mouse on your PC,
for that you need to have an app that can work with it.(check out this Github Repo for more info: https://github.com/pelya/android-keyboard-gadget)
I have enabled F2FS on this kernel as well,
Currently, I need people to test out its battery backup and provide feedback about performance and bugs
Currently Known Bugs:
None
You tell me of you find any!
Instruction are just as usual, if you need help, head to the "Post #3" of this Thread.
Update Logs are available in "Post #2" of this Thread.
Download Links are over at Android File Host!
Feature requests are welcome, you can post your feature requests here, or head over to github and open a new issue for bug report and/or feature requests.

[CLOSED]CRUEL KERNEL S10 V2.3

CRUEL KERNEL S10 V2.3
The development moved to this thread. From V3 kernel supports multiple devices.
Introduction
This kernel is based on BTA8 samsung sources. Only G973F device for now. It is possible to use it on BSKO, BSL4, BTA8 firmware. All sources are open on GitHub.
Continuous integration with GitHub Actions is set up. This means you can customize the kernel from browser and build the version suitable for you without leaving the browser (see сustomization section).
Features
Customizable build with config presets
Only part of samsung security features disabled (DEFEX, Process Authentification, root restrictions)
Switchable SELinux (by default it's locked in "always enforcing" mode in samsung sources)
Built-in in Magisk
Wireguard for VPN
CIFS for SMB
Iptables TTL and HL editing modules for bypassing tethering restrictions
Build commands (configuration presets) used for V2.3 kernel:
Code:
$ ./build mkimg name=CRUEL-V2.3-BTA8 +magisk +nohardening +wireguard +ttl +cifs
$ ./build mkimg name=CRUEL-V2.3-BTA8-CANARY +magisk+canary +nohardening +wireguard +ttl +cifs
Installation Instructions
First of all, TWRP Recovery + multidisabler should be installed in all cases. This is a preliminary step. Backup your existing kernel. You will be able to restore it in TWRP Recovery in case of any problems.
Dowload an *.img file and
With TWRP: Reboot to recovery. Install > Install Image > CruelKernel.img > BOOT.
With Heimdall: Reboot to Dowload mode.
Code:
sudo heimdall flash --BOOT CruelKernel.img
With FK Kernel Manager: Flasher > Manual Flasher.
ChangeLog
V1 is based on BSKO sources and was privately used. You can find V1 by the link.
V2 is based on BTA8 sources. nohardening, nohardening2, cifs configuration presets added.
V2.1 is for internal use only (testing release) +nohardening preset activated by default
V2.2
Canary Magisk updated to 20305 version
MALI_KUTF kernel driver removed (it's required only for kernel developers)
Pin code problem fix (thanks geiti94)
+nohardening (disable samsung protections)
V2.3
Canary Magisk updated to 20306 version

How to customize the kernel build
It's possible to customize the kernel and build it from the browser. First of all, create and account on GitHub. Next, fork this repository. Switch to the "Actions" tab and activate GitHub Actions. At this step you've got your own copy of the sources and you can build it with GitHub Actions. You need to open github actions configuration file (.github/workflows/main.yml) and edit it from the browser. For example, to alter the kernel configuration you need to edit lines:
Code:
- name: Kernel Configure
run: |
./build config name=CRUEL-V2-BTA8
+magisk
+ttl
+wireguard
+cifs
You can change the name of the kernel by replacing name=CRUEL-V2-BTA8 with, for example, name=my_own_kernel. You can remove wireguard from the kernel if you don't need it by changing "+" to "-" or by removing the "+wireguard" line and "" on the previous line.
Available configuration presets can be found at kernel/configs folder. Only the *.conf files prefixed with "cruel" are meaningful. For example:
magisk - integrates magisk into the kernel. This allows to have root without booting from recovery. Enabled by default.
magisk+canary - integrates canary magisk into the kernel.
ttl - adds iptables filters for altering ttl values of network packets. This helps to bypass tethering blocking in mobile networks.
wireguard - adds wireguard VPN module to the kernel.
cifs - adds CIFS (SMB) support.
nohardening - removes Samsung kernel self-protection mechanisms. Potentially can increase the kernel performance. You can enable this config if you face rooting or some other kind of restrictions. Other kernels usually use settings from this config by default. It's safe to enable this config, it just makes your system less secure.
nohardening2 - removes Android kernel self-protection mechanisms. Potentially can increase the kernel performance. Don't use it if you don't know what you are doing. Almost completely disables kernel self-protection. Very insecure.
nodebug - remove debugging information from the kernel.
300hz - increases kernel clock rate from 250hz to 300hz. Potentially can decrease response time. Disabled by default, untested.
1000hz - increases kernel clock rate from 250hz to 1000hz. Potentially can decrease response time. Disabled by default, untested.
For example, you can alter default configuration to something like:
Code:
- name: Kernel Configure
run: |
./build config name=CruelCanary
+magisk+canary
+wireguard
+nohardening
After editing the configuration in the browser, save it and commit. Next, you need to switch to the "Actions" tab. At this step you will find that GitHub starts to build the kernel. You need to wait about 25-30 mins while github builds the kernel. If the build is successfully finished, you will find your boot.img in the Artifacts section. Download it, unzip and flash.
To keep your version of the sources in sync with main tree (following updates), please look at this tutorial.

topjohnwu for Magisk
geiti94 for showing that it's possible to built-in Magisk into the kernel. Initially I experimented with ASIG kernel, but ASIG+Magisk on ASIG firmware just stucks on boot with an SELinux initialization problem. At that time I doubted that built-in Magisk will work.
geiti94 for his help and advices

How to build the kernel locally on your PC
This instruction assumes that you are using Linux. Install: mkbootimg, heimdall (if you want to flash the kernel with it).
Next:
Code:
$ git clone https://github.com/CruelKernel/exynos9820-beyond1lte
$ cd exynos9820-beyond1lte
# List available branches
$ git branch -a | grep remotes | grep cruel | cut -d '/' -f 3
# Switch to the branch you need
$ git checkout samsung-g973f-bta8-cruel
# Install compilers
$ git submodule update --init --recursive
# Compile (install mkbootimg first)
$ ./build mkimg name=CustomCruel +magisk+canary +wireguard +ttl +cifs +nohardening
# You will find your kernel in boot.img file after compilation.
$ ls -lah ./boot.img
# You can automatically flash the kernel with heimdall
# if you connect your phone to the PC and execute:
$ ./build :flash
# Or in a single command (compilation with flashing).
# ./build flash name=CustomCruel +magisk+canary +wireguard +ttl +cifs +nohardening

What ROM are you using? I tested it mostly on samsung BTA8 firmware.

If your phone was able to boot to pin screen, then I doubt the problem is in bootloader. Could you try V1 kernel https://github.com/CruelKernel/exynos9820-beyond1lte/releases/tag/v1.0
If it will work, then probably V2 will also work with +nohardening option. V1 compiled with this option, V2 without it. I will rebuild V2 then.

Same thing with version 1.could it be the twrp im using?

No, it's definitely not related to twrp. Well, I don't know what is an exact problem here, but some guys told me they were able to flash the kernel on ambassadi with data wipe or immediately after flashing the rom itself.

It would be very nice if people will just write if the kernel works or not on their roms. This will be a huge help for me.

Data wipe should be enough. I will test compatability with Ambassadi today-tomorrow and will provide more detailed feedback. Thanks!

hello installation successfully the nikel kernel market for now

Does this work with BSL7? Or know of kernel that will. Need my su permission to work

Hi, no it will not work on BSL7. This kernel is for S10 (G973F) device. This device has only BSL6 firmware. BSL7 is for other devices. Try to look at nemesis kernel.

Is it possible to build magisk rooted kernel for pie (9) roms? Or it's only for Q like LOS 17?

Download: https://cruelkernel.org/release/special/CruelKernel-G973F-ASJG-v1.1-LOS.img
This version is based on Android 9 (ASJG) sources and should work on ASIG firmwares. I've included some patches from ivanmeler LOS tree specifically for LOS. Features: Magisk v20.3, wireguard, ttl modules and cifs. Not tested

will he s10+ every be supported with this kernel?
