What's difference between GSI enforcing and Permissive?
Google has answers to such simple question :)

SELinux status:
Permissive means SElinux is disabled. Some ROMs need to execute some commands in order to be able to boot and they need high level permissions. So SELinux needs to be permissive

Enforcing means SElinux is enabled.
So ROMs or apps don't get high level permissions. Therefore making your phone more "secure" to malicious apps

Samsung Galaxy A10
Hello, I am currently using the ultimate q and it's awesome!!! and @Chatur27 just so you know it does support VoLTE.
Now, back to the main scene. So, what happened is i tried the one ui variant for this kernal in the ultimate q rom and i am having a random reboot issue. So, i tried to find a solution and also found one!!! but this is temporary.. It seems that when the kernel cpu is set to 2184 mhz(which is set as a default) it starts to reboot randomly and decreasing it stops the random reboot (at least till now), so please try look into this issue. Thanks.

Hi, Ty for your feedback
Due to some minor manufacturing defects in industries, not all phones are manufactured the same even of they are of the same model.

Some A10 phones cannot handle the 2184 MHz frequency.
So, please flash the file below each time u flash eureka kernel so as to limit max frequency of big cores to 2080 MHz. Ty!

Whats difference between gsi and one u performance and enforcing thing?

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 kernel is the solution for both gaming and performance on our cheap A10.

Compatibility:
This kernel has 3 versions. One version works only on ONE UI (can be stock or debloated ONE UI) and the other 2 versions work on GSIs and custom roms (GSIs built specifically for A10). 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 2184 MHz.​
LIL Cores: from 1352 MHz to 1690 MHz.​
* Underclocked CPU as follows:
BIG Cores: from 936 MHz to 312 MHz.​
LIL Cores: from 839 MHz to 343 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
* 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 4.4.267 which is the latest stable version.
* Built with Proton Clang 13 toolchain with LTO. Reason: Better performance
* FOR GSI:
* Fixed ADB and MTP.​
* Set SElinux as permissive​

Please read the changelog for full list of changes.

KNOWN ISSUES:
*None


SOME MINOR TWEAKS FOR BEST GPU PERFORMANCE:
* Set GPU power policy to "always on"
* Set min and max GPU frequency to 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.

Mano eu tenho problema na hora de instalar o kernel na rom stock toda vez que eu tento instalar meu fica brikado e eu tenho que instalar a rom stock denovo. Me ajuda aí tenho um a10 sm-a105m

Translation: Man I have a problem when installing the kernel in the rom stock every time I try to install mine it gets briked and I have to install the rom stock again. Help me out there I have an a10 sm-a105m

I think it is only fo4 a105f, I don't know, but! Sorry for that! I hope you never stuck in a boootloop again.

If you are having issues with stock rom, then just install debloated stock roms or custom roms!
Stock roms have securities which can cause issues

Eureka R7.0 update for A10

Changelog:

-> Switched unified kernel source to A40 R latest source

-> Updated Wireguard driver to latest version

-> Fixed low torch/flashlight brightness on custom ROMs (dtbo based)

-> Increased A10 input charging current upto 1.2 A (dtbo based)

-> Some tweaks to reduce jitter and UI lags

-> More battery tweaks to reduce idle battery drain

-> Added support for exFAT filesystem

-> Upstream Linux Kernel Version from 4.4.267 to 4.4.270

-> Fixed almost all warnings in kernel source

-> Improvements to MTP and ADB driver

-> Nuked inefficient Exynos Hotplug driver. Replaced it by another hotplug driver.

-> You can manually turn off cores to save power but at the cost of performance.

-> Custom dtbos/spectrums are/will be available for customizing the kernel to your needs.

-> There will be only 2 kernels as from now, namely enforcing or permissive. Works on custom roms, gsi and oneui based roms.

-> Fix the issue where the 2 lower gpu frequencies had the same voltage when -100mv was applied to them.

    EK A10 XDA.jpg

    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.

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

    Update: I got stuck at samsung logo

    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.
