Hi all,
this is the thread for a custom kernel i made for Samsung Galaxy A10.
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 on our cheap A10. 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 and the one is called R. Q/R kernels can only be used on Q vendor based roms, that is, ONEUI 2.x, Q/R GSIs, Q/R Eureka Roms. R kernels can only be used on R based vendor, that is, ONEUi 3.x for the time being

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 1560 MHz to 2288 MHz.​
LIL Cores: from 1352 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 676 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/gsis
* 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 4.4.277
* 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.

Good afternoon, everyone, I want to leave a review for EUREKA KERNEL 4.4.3, the update hasn't really changed anything, but the work of the RAM memory is different, applications often crash out of the RAM memory, , with update 4.4.3 I can use only 1 application, the rest crashes within a minute, I solved the problem by rolling back to version 4.4, Please fix the RAM, thanks a lot.

Well, I didn't do anything with ram.
Kindly let me know which os you are using

use ex kernel manager and enable zswap

Is there any way to increase multi touch count/slots to 10 !

Update: I got stuck at samsung logo

Update 2 : magisk cause bootloop and to avoid that you should remove magisk from inside "Eureka_kernel/ramdisk" folder then flash it via recovery, it should work just fine..

Eureka kernel brings HUGE improvement in performance and gaming.
thank you @Chatur27 for the awesome support and for this awesome kernel.

Device : A105f 2GB ram version

Samsung Galaxy A10
I use ultimateQ ( which a debloated version of oneui 2.0) and I don't get any such issues.
I don't even need to enable zswap (except for high end games)
Does it support volte? I have tried to install the selinux enforcing version but it won't boot up the permissive one is working fine but is there a way to change it to enforcing manually? And also(this is the last) did you flash the one ui version for ultimateq since it's a debloated stock?
Your kernal is doing awesome ....great job..keep up the good work.

Volte is oneui rom feature. dont ask me about volte. Ty.
Enforcing version won't boot because your custom rom needs permissive. Change rom if you want enforcing SElinux

    Eureka R7.5 update

    Changelog:

    → Upstream Linux Kernel Version from 4.4.270 to 4.4.277
    → Enabled back 208 MHz frequency for big and little cores.
    → DTB is now used to customize Eureka features such as CPU and GPU frequencies.
    → DTBO is only used to disable dm-verity as from now.
    → Added a new flashlight control driver which will be used on AOSP/LOS based ROMs. It will also fix low flashlight issue on GSIs. This new driver does not interfere with camera (which was causing dark photos for some A20 users) Footej camera app is recommended for custom roms.
    → Imported latest Samsung updates from A305F R kernel source.
    → "Samsung A10 1.2A input charging current" feature still depends on Eureka dtbo. Will fix it on next update
    → Further overclocked BIG cores from 2184 MHz to 2288 MHz and LITTLE cores from 1690 MHz to 1794 MHz.
    → Fixed wrongly set GPU throttling frequencies.
    → Updated WireGuard vpn driver to latest version - v1.0.20210606
    → Some other minor optimizations.
