Changelog:

→ Upstream Linux Kernel Version from 4.4.277 to 4.4.288
→ Added ondemandplus CPU governor.
→ Added BFQ and ZEN v2 I/O schedulers.
→ Added a new backlight brightness controller. [Feature can be used when new EKM app is released] [Experimental]

Check in setting if your SELINUX es on permissive or enforcing i think
then flash such file on twrp (i think you should be able using adb or odin)

 

[GloBoB]

Great job on this kernel, its excellent
I have some problems using it on HAVOC OS 4.8 causes to random reboot or freeze screen, causing have to flash firmware kernel and starting all over again

 

[Itsmewall.]

after I installed it, my earphones were not detected so the sound did not appear, the sound only appeared on the cellphone, is there a solution?

Hi all,
this is the thread for a custom kernel i made for Samsung Galaxy A30.
The custom kernel has been named Eureka which is a greek work which means "I have found the solution". This multi-purpose kernel is the solution for battery, gaming, performance for A30. On creating this kernel, I believed that 1 kernel can be all of the above if properly tweaked!

Due to Samsung heavy changes in R vendor (Oneui 3), 2 kernels had to be made. One kernel is named Q/R/S and the one is called OneUI3. Q/R/S kernels can be used on ONEUI 2.x, Q/R/S GSIs, Q/R/S Eureka Roms. OneUI 3 kernels can only be used on ONEUi 3.x roms

Compatibility:
Each of the 2 above mentioned kernels has 2 versions. One version has enforcing selinux and the other one has permissive selinux. So, please download the correct version.

FEATURES:
* Disabled Samsung security features
* Enabled all governors + added other governors
* Overclocked CPU as follows:

BIG Cores: from 1768 MHz to 2288 MHz.​

LIL Cores: from 1586 MHz to 1794 MHz.​

* Underclocked CPU as follows:

BIG Cores: from 936 MHz to 208 MHz.​

LIL Cores: from 839 MHz to 208 MHz.​

* Added GPU thermal and voltage control
* Added latest boeffla wl blocker V 1.1.0 and disabled some wakelocks
* Network speed improvement
* Enable zram support and set default compressor as lz4.
* Switch to a lower charging voltage more quickly.
* GPU max frequency overclocked from 845 MHz to 1300 MHz
* Implemented Dynamic FSync 2.0
* Implemented a custom hotplug driver to enhance battery management
* Implemented Power Suspend driver
* High torch brightness on custom roms
* Has Spectrum support
* Automatic detection of magisk - If u are rooted, u don't need to flash magisk after kernel.
* Upstreamed kernel version from 4.4.177 to 4.4.288
* Built with Proton Clang 13 toolchain with LTO. Reason: Better performance

Please read the changelog on github for full list of changes.

KNOWN ISSUES:
* Maybe ADB cannot be used at the same time as MTP

SOME MINOR TWEAKS FOR BEST GPU PERFORMANCE:
* Set GPU power policy to "always on"
* Set min and max GPU frequency to 1200/1300 MHz
* Disable GPU thermal manager to prevent GPU frequency from dropping
* Games don't require high CPU frequency because they depend more on GPU. You can therefore decrease CPU max frequencies to reduce heating of the device.

* نسخه کرنل Upstreamed از 4.4.177 تا 4.4.288
* ساخته شده با Proton Clang 13 toolchain با LTO. دلیل: عملکرد بهتر

لطفا تغییرات را در github برای لیست کامل تغییرات بخوانید.

مشکلات شناخته شده:
* شاید ADB نمی تواند همزمان با MTP استفاده شود

برخی از ترفندهای جزئی برای بهترین عملکرد GPU:
* خط مشی برق GPU را روی "همیشه روشن" تنظیم کنید
* حداقل و حداکثر فرکانس GPU را روی 1200/1300 مگاهرتز تنظیم کنید
* برای جلوگیری از افت فرکانس GPU، مدیر حرارتی GPU را غیرفعال کنید
* بازی ها به فرکانس بالای CPU نیاز ندارند زیرا بیشتر به GPU وابسته هستند. بنابراین می توانید حداکثر فرکانس CPU را برای کاهش گرمایش دستگاه کاهش دهید.

please for nethunter kali Make thank you

 

[ardasher]

please for nethunter Build

 

[Chatur27]

please for nethunter Build

My kernel source is opensource. You can fork it and build whatever you want with proper authorship.

its oneui issue. You have to delete samsunghealthservices and gameoptimisingservice apk from system.

 

[Chatur27]

after I installed it, my earphones were not detected so the sound did not appear, the sound only appeared on the cellphone, is there a solution?

You flashed the wrong version of the kernel. There is a version for roms based on Q vendor and one for roms based on R vendor.

you mean this one? yes, what i installed is this one, should i install the oneui one?

 

[rezabahramnezhad]

In Eureka 8.0.1 camera not work and I have lag on 8.0

 

[Chatur27]

In Eureka 8.0.1 camera not work and I have lag on 8.0

U used QRS kernel on Oneui 3 or R vendor roms
Use oneui3 kernel please
8.0.1 is only for Oneui2, or Q vendor roms

→ Implemented EurekaSound (ESOUND) v1.0, a basic headphone audio controller (For AOSP only).
→ Implemented Eureka Display Control (EKCAL) which is based on Samsung mDNIE driver (Not available for A20e).
→ Modified DT2W driver for A20 and A40 so as to fix DT2W issue on AOSP ROMs.
→ Fixed all remaining warnings in kernel source.
→ For permissive selinux, selinux can be switched to enforcing after boot.
→ Further improvements to SElinux code to fix some warnings in kernel log.
→ Fixed custom flashlight controller for A10.
→ Updated WireGuard VPN driver to latest version (1.0.20211208)
→ Merged 98 % audio and camera changes from R kernel source into Q/R/S (AOSP/OneUI2) kernels.
→ AROMA Installer is now used to facilitate the installation of Eureka Kernel.
→ OneUI and AOSP kernels & custom DTBs have been merged into 1 zip (kept size as small as possible).
→ Built with Vortex Clang & LTO which is based on the latest version of Clang 14 (20220201).
→ Two kernel versions with different schedulers are now available:

→ Implemented EMS (Exynos Mobile Scheduler) which is a scheduler based on EAS (Energy Aware Scheduling).​

→ The normal kernel version has the stock HMP (Heterogeneous Multi-Processing) scheduler.​

​

→ Eureka kernel R9.0 heavily depends on DTB (not DTBO) for the following features:
→ CPU and GPU overclock & underclock
→ SELinux state (enforcing or permissive)
→ Sound driver compatibility (AOSP, OneUI2 or OneUI3)
→ Energy model and parameters for EMS kernels
→ EMS kernel works best with schedutil based governors. The following governors were added:

→ Blu Schedutil
→ ElectroUtilX
→ PwrUtilX​

→ Updated to latest A305F kernel source (A305FDDU6CUI3).
→ Time left for full charge is now shown on OneUI ROMs.
→ Updated all DTBOs to match latest changes from R source.
→ Possible fix for issue of glitched video renderings on social media apps (E.g: Instragram) - reported by our testers.
→ DTC (Device Tree Compiler) on kernel source has been upreved to 1.6.1, latest available
→ Updated spectrum files.
→ Other minor changes.
