Details:
Based on latest Samsung open source drop​
Compiled with the Clang 12 + full LTO GCC 12.2​
Instructions:
Assuming you have a custom recovery installed, simply download and flash the kernel zip. This kernel uses Anykernel 3 so no need to reflash magisk(if you use magisk) after installing it.

it should if you can unlock your bootloader and have TWRP or root.

¡¡¡¡Genial !!!!!
Maybe Open my bootloader .... !!!! Thanks for your time and work.. !!!

it's a great kernel thanks for your work

This kernel is based on G780GXXU3AUH5.
Does this kernel also work on the G781B?
I'm on FW G781BXXS4CUJ2.

Download the build that you're in, extract the AP file and then, extract boot.img.lz4 from AP. Recompile the boot.img.lz4 to .tar with 7-zip, so you can flash with Odin.

if he's flashed this kernel with TWRP he can flash the extracted boot.img with TWRP (flash image).
@HarryCustom you'll need to download a command line app for LZ4 from github and figure out the command to extract the boot.img but it's not difficult.

Ok thank you I'll do it!
Anyway I own a G780G/DS, I only report that to me the kernel gave problems for anyone else who wants to use it with the same phone as me!

Still facing issue:-
Maybe u where on a rom which had encryption
Take a backup of your Data into u laptop or desktop
Flash twrp 3.5.0_9
Wipe everything
Flash rom

flash gapps (Nik Gapps only)
Magisk 22
reboot
Hi,
first of all, thanks for your work.
I installed the ROM CR 7.3 doing Clean flash.
The phone booted correctly and I was able to play around a bit.
After enabling encryption, under Security, the phone started bootlooping.
Right after crdroid logo kept rebooting.
Does anyone know if it's a known issue?
Thanks
NEW BUILD UP:-
=========================
MAR 12 , 2021
=========================
+ Bump to V7.4
+ Mar 2021 Patch
+ Based on New Trees,Kernel and Vendor
+ Kernel Upstream to 4.4.261
+ Merge tag 'LA.UM.8.2.c25-01600-sdm660.0
** NOTE ONLY CLEAN FLASH ALLOWED **
** TWRP is removed from this build **
at last, a complete ROM with all the features I want and haven't experienced any bugs other than my screen going black one time and having to restart. overall best ROM for me. thank you so much for your work
I've tried this ROM on 2 mi a2. It runs really smooth, it's nice. Android 11 is cool, with quite a lot of small enhancements but I encountered several critical issues :
1/ no mobile data with one of my provider (bouygues telecom). The other SIM was OK, i've swapped them to check, nothing changed
2/ GPS can't work. 0 sattelite. This is critical to me -> I've turned myself back to lineageOS on which GPS and data are both properly working.
Anyway, continue like that guys, you're doing a great job !

Development [Kernel][1.6.2022] Sekiyama 1.3 for Moto G Stylus 5G "osaka"

Sekiyama-Kernel for Moto G Stylus 5G
The kernel is based on sources from @Electimon which can be found here.
Features:
Main Features:
- Based on kernel sources from Motorola
- New performance based scheduler "dragrace" which prefers max clocks during screen usage.
Your battery milage will vary. With heavy usage I average about 10% for every 3 hours of background playback while still maintaining overall battery life when I forgo usage.
- Exfat support for external SD Cards
- Disabled ZRam
To improve memory latency
- Updated to 5.4.147 (stock is 5.4.61) thanks @Electimon
- This kernel is non-modular! All vendor modules are baked into the kernel. This includes sensors, audio, networking, and display.
- Use bbr as default TCP congestion algorithm (fastest algo according to this excellent research from @kdrag0n found here )
- Removed ALL debug config options and disabled printk
- Wireguard Support
- Magisk Stub integrated

Seems to be failing safetynet. I should have a solution by next release.
Hi everyone, on my device (XT2131-1, Spectrum Mobile), this kernel causes some stuttering, especially when entering the password to unlock. Is this a known issue?
Thanks in advance.

Next release should fix your issues!
New update released. This brings many changes such as disabling Zram to improve system latency, new cpu scheduler "dragrace" as default (prefers higher clocks while screen is active), and fixes to SD Cards. Also, I improved support for those of you who installed the TWRP ramdisk. Enjoy!
Can confirm the update fixes the stuttering issues, at least for me. Thanks for the work!
Working well and no noticeable stutter now. Also the flag at UI start is resolved. Here is a twrp recovery log.
Works on Android 12 Pixel rom gsi...
only thing is i dont see the new scheduler dragrace you mentioned in the update.
see pic..
thanks again ,,the data speeds are better than the pure stock boot.img.

Do chat features (text, mms) and calling work on this gsi? Caos and Lir need a bit more work than I can muster to give at the moment.

I updated to the new gsi 12 and re-flashed the kernel via fastboot method and now i see the new governor...kernel working well.
i installed it after i ported the boot.img_kernel .
great work
features for next release:
fsync on/off
lrng/drng switching
simple LMK (low memory killer)
if you there are features you wish to have that i haven't named, don't be afraid to ask!

My only request would be gpu boost from 650mhz to 750mhz would be awesome...
prioritize audio option to reduce audio latency
How are updates looking? @ArtiicPanda
Edit: Also to go with the GPU boost requested above, a slight CPU overclock would be amazing. This phone gets such good battery life I think it would be worth the tradeoff. Maybe make 2 versions of the kernel -- one normal, and one "performance" with gpu/cpu overclocks and let people choose
Edit2: Also noticing that the "tap to wake" feature gets a little wonky once the device hits (what I assume) is deep sleep. Takes 2 sets of taps to get the screen to come on. Somewhere around 45 seconds to a minute after turning the screen off and leaving the device alone. Any time before that, works exactly as intended. Definitely kernel related as it's the only difference between my unlocked model and the Cricket next to it.
Edit3: Also perhaps enabling the "notification led" on the front?

[KERNEL][17.12.22][A12][A13] Stock Kernel with exFAT for Pixel 4/XL

Stock kernel with upstream exFAT driver for Pixel 4/XL
Background
Read about the Google Pixel 6/Pro getting official exFAT support in Android 13 on an Esper article and dug around the source code for Android's vold. Seems like Android has "supported" exFAT since Pie/9 with this commit in platform/system/vold as long as the device comes with 1) exFAT driver in the kernel, 2) mkfs.exfat and fsck.exfat in /system/bin(weird that Google doesn't include this in Android). Thankfully, both are available for all devices with Linux kernel > 4.1 through the linux-exfat-oot exFAT driver and exfatprogs, both provided by the official Linux exFAT driver maintainer, Namjae Jeon. Some compilation and git clone-ing later and, here we are!
Code:
/*
* Your warranty is no longer valid, unless you lie.
*
* I am not responsible for bricked devices, strained relationships,
* 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.

Changelog
17-Dec-22
- Latest Android 13 kernel source for Pixel 4/XL
- October security patch
11-Jul-22
- First release
- Added exFAT driver as git submodule under Google's stock kernel sources
- July security patch
- Disabled some kernel debugging code
[Guide] How to port this to other Android devices
Requirements
- Android phone with Linux kernel >= 4.1
- armv7 or arm64 SoC/CPU
- CLI experience and a Linux PC with decent RAM/CPU for compilation
Points to note
- LTO/CFI takes a huge amount of RAM if your PC's CPU has a lot of cores since the LTO operations are parallelised. I couldn't find a flag to disable parallelisation/multi-threading of LTO so I had to enable ZRAM to give lld enough RAM. For me, I had a 4-core/8-thread CPU(Intel Core i7-8809G) with 32GB RAM and lld managed to eat up 19GB-25GB RAM(Jun security patch took 19GB, Jul security patch took 25GB before lld got killed due to OOM, didn't check RAM usage on successful compilation) when run with make -j2
Steps
1. Download your device's kernel sources
2. Add namjaejeon/linux-exfat-oot to fs/exfat under the kernel source, either as a git submodule or just download the repo as a zip and extract it
3. Perform steps 2 & 3 of jamjejeon's guide
4. Enable the exFAT driver by running 'make ARCH=<device architecture> <defconfig file>' and 'make ARCH=<device architecture> menuconfig', and then going to 'File systems' -> 'DOS/FAT/NT Filesystems' -> Press 'Y' key of your keyboard after moving the highlighted option to 'exFAT filesystem support'
5. Compile your kernel
6. Take the generated Image(.lz4)(-dtb) and dtbo.img files and use AnyKernel3 to generate a flashable zip
7a. Install either the 'magisk-exfatprogs-aarch64-v1.zip' or 'magisk-exfatprogs-armv7a-v1.zip' file attached below, depending on whether your device is 64-bit(aarch64) or 32-bit(armv7-a)
7b. You can also cross-compile exfatprogs from source by setting up the Android NDK according to Google's Use NDK with other build systems guide(autoconf section)
This too
Sorry for the delay, here's the latest stock kernel with exFAT support added for those on the final update of Pixel 4/XL, Android 13 October patch! Installation steps are the same as before. I'm not sure whether it'll support earlier stock Android 13 builds though, try at your own risk! Hope this is useful!

hi XDA community, i'm here to share with you my little project, my primary goal is to provide a stable and fast kernel without compromising battery life, plus some cool features that i find useful for the day to day usage.
Current Features
General List:
Compiled using Google's environment for GKI kernel build for maximum stability using latest google prebuilt clang 14.0.7
Packed with Anykernel3 with ability to preserve magisk root
Works on both devices (Pixel7 and Pixel7PRO)
Update system support via flasher apps ( Copy/paste link for auto updates )
Boeffla's wakelock blocker
BBR TCP set default and a lot more others to choose
SSG io scheduler set default and preconfigured
Enabled power efficient workingqueues on various drivers
Fsync on/off support
CleanSlate Features from @tbalden, all credits for the features to him (s2s, notification booster, battery saver, flashlight notifications. Note that rootless features like kadaway are not implemented here because we need root for other features to work properly with my tree)
Multi-gen LRU driver
Simple Low Memory Killer from SultanXda
Switched to SCHED_RR instead of SCHED_FIFO
DAMON driver (disabled by default for now)
Removed some debug options
Changes to some drivers to use Big cpus or viceversa ( hardware composer, goodix... Etc)
Other stuff that is boring to write, take a look at my github for detailed information
ONLY COMPATIBLE WITH 2023 JUNE'S A13 STOCK GOOGLE ROM
[ RADIOACTIVE KERNEL INSTALL ]
Keep in mind that vbmeta flags for verity/verification must be disabled before flashing the kernel otherwise it will not boot and disabling those flags will wipe your device.
DOWNLOADS HERE
CHANGELOG
There's a flashable zip that can be flashed with your preferred kernel tweaker app and/or alternatively you can extract and flash all images using fastboot if you want
Radioactive Kernel fastboot images flashing instructions:
Flashing manually:
vendor_dlkm.img needs to be flashed in fastbootd, while the other images needs to be flashed via fastboot/bootloader.
How to boot to fastbootd?
From running phone:
adb reboot fastboot
From fastboot/bootloader:
fastboot reboot fastboot
Once in fastbootd:
fastboot flash vendor_dlkm vendor_dlkm.img
Boot from fastbootd to fastboot/bootloader to flash dtbo.img, vendor_kernel_boot.img and boot.img:
Either select Reboot to bootloader option via buttons
or type:
fastboot reboot bootloader
Now in fastboot flash boot.img, dtbo.img and vendor_kernel_boot.img
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vendor_kernel_boot vendor_kernel_boot.img
Reboot either via buttons
or by typing
fastboot reboot
Enjoy!!!!
Instructions using Ex kernel manager or any other app with autoflash support:
* Flash Kernel Zip
* Reboot
* Enjoy!!!

When i had the pixel 6 this kernel was the best of all.
Thanks.
I have been waiting for this as well.
Glad it's finally here.
Thanks for sharing and Thank you for all your hard work. It's very much appreciated!
Bootlooping on HentaiOS. Just in case anyone wants to try it out. FYI
Do I need vbmeta flags for verity/verification disabled for this kernel to work ?

As far as i know, those flags must be set for any custom kernel.
Please correct me if i'm wrong.
Gotta say I'm loving having a few kernels and roms to play with. Starting to almost kinda feel like the good old days of the Galaxy S Vibrant (RIP). Also, your update URL for the flasher apps is absolutely awesome. I've never had that feature before. I immediately put the URL in Franco's Kernel manager and was dumbfounded when the kernel popped up. Absolutely awesome. Also, the kernel is doing great. I flashed it twice. Once in fastboot and once in FK Manager. I only did it both ways to make sure I wouldn't bootloop. Kudos for a good kernel, my dude.

The following commands doesn't seem to work for me in all kernel mods I've tried here. Does this come with wifi hotspot tethering limit bypass by default? Or will the below commands work?
settings put global tether_dun_required 0
net.tethering.noprovisioning=true

This is definitely the best kernel around for pixel. It's simple, no extra tweaking on the configuration. Plug and play. @acuicultor created the best kernel for p6 and I'm sure it's the same for p7. I'm waiting for LOS to update in order to flash RAk .

Can your kernel be flashed on top of Cleanslate using any of the Kernel Flasher's or does it have to be manually flashed in fastboot and fastbootd

You can flash on top of any other kernel but is always recommended to flash stock kernel before flashing any custom kernel.

Great kernel
Good to see an alternative to Kirisakura and Despair
What about cleanslate? tbalden it's actually one of the real devs that still remain writing original code.
