@physwizz I will continue the conversation about underclocking here instead of hijacking Eureka thread...
You could do a test build with Eureka underclocks and compare the current draw with cpus idling to your present underclocks. There will be a "Goldilocks" point at which it is pointless to underclock any further that is directly related to the 14nm architecture of our SOC.

Sure
What minimums would you like?
@physwizz I don't know what minimums until someone does a scientific test on what minimums yield the best idle current reduction without causing excessive stuttering off the mark....
At a guess, I would be expecting somewhere in the 300MHz range to be the sweet spot.

Are the only ones in the 300s
Next highest are
Big 520
Little 449
@physwizz Unfortunately the comparison between Eureka running at 520 big, 449 small and your 312 big, 208 little is not valid since there are so many differences in the kernels other than the underclock freqs. What is valid is comparing your kernel with the current underclock to the exact same kernel with the next freq up underclock. That would be an almost scientifically valid test.....

MoleculeKernel v0.1 - 09 Feb 2014
NOTE:
I am not a developer, just a modder and an Android enthusiast.
I create/mod/build ROMs and kernels for myself, and want to share with XDA members.
I don't want anyting in return, my work might not fit your needs.
Thanks.
FEATURES:
Compatible with N5100 and N5105
Based on N5100XXCMK1 - Samsung's latest open source kernel
Only compatible with 4.2.2 Samsung ROMs
Extra governors (pegasusq, SmartassH3, zzmoove, lulzactiveq, adaptive, interactive, conservative, ondemand, userspace, powersave, performance)
Extra schedulers (cfq, noop, deadline, row, vr, sio)
Undervolting support
Overclocking support CPU up to 1.9 Ghz
GPU frequency: 533 Mhz
Memory leak fix
Archpower support
TriangleAway 2.90 support
This kernel made from Samsung's latest open source kernel so it includes latest fixes from Samsung.
NOTES:
I tried make kernel stable as possible, so I didn't add much changes to Samsung's code.
I didn't add shell scripts or init.d fixes to ZIP, to make it light and stable.
Most of code from civato, andreilux and other devs. Thanks to all of them.
Kernel is NOT overclocked by default. But minimum CPU freq. reduced to 100 mhz (stock kernel=200 mhz) (when your tablet does not require much processing power, this will improve battery life.)
Source code is available: http://github.com/whitemolecule
TOOL TO CONFIGURE THIS KERNEL
I recommend Trickster MOD = https://play.google.com/store/apps/details?id=com.bigeyes0x0.trickstermod
TRY MY CUSTOM ROM
You can also try my custom ROM with this kernel: http://forum.xda-developers.com/showthread.php?t=2643590

Thanks. I think default governor and frequency settings are most stable ones in terms of battery life and performance for most users. It really depends on how you use your device.

TricksterMod->Specific->GPU Frequency Settings -> Step4. I can see frequencies from 200 to 700 there.
@op, do you have your sources per chance?
Any chance to get this Kernel for CM11 ?, just curious. And excellent work BTW.
Thanxs ... you make my note happy!

Yes u can see it, but after setting step4 to 600 it skips back to 533... (for me...)
Still testing, but everythings seems working, good thing to have a custom kernel, stay tuned :good:
It is all right that kernel, congratulations.
I would like to include it in the next my update ROM rebel note8 much
How to install this kernel? I use stock rom, stock kernel, and stock recovery
Thanks
Sent from my GT-N5100 using Tapatalk HD
does this kernel support uinput and tincore keymapper?
Thank's
Thank's for this great job.
I get your kernel source and make some changes, can you include in next versions?
I enabled samsung docks:
CONFIG_MUIC_MAX77693_SUPPORT_OTG_AUDIO_DOCK=y
CONFIG_MUIC_MAX77693_SUPPORT_SMART_DOCK=y
CONFIG_MUIC_MAX77693_SUPPORT_CAR_DOCK=y
With this I can use OTG and charge at the same time, as some people does with s3 ( http://forum.xda-developers.com/galaxy-s3/general/hw-mod-usb-otg-charging-galaxy-s3-t1953061 ), same resistor values.
I also enabled support for some usb serial adapters and some usb network adapters.
See ya, and again, thank's

I tested with Vanir (Unjustified Dev), OmniRom (golden_guy), Pac-Man (tenshi_xp), CandyKat (PolishVodka), SlimKat (Android-Andi) and CyanogenMod (novafusion)
I tested for a long time 1050, 1100 and 1150 on OmniRom and Cyanogenmod and on Omnirom 1050 caused problems this is why i have removed .
With others ROMs I did not encounter any problem, but it was fast test, thus do not hesitate to indicate what you will meet
I will try it out for omnirom by golden-guy and give feedback

100 - 1100 works.
on 1150 i got kernel panic
It's working on Spirit ROM (v1.4): you can add it to the compatibility list
Hi! Great work Tested for now on Andi's Slimkat and looks good :good: Tried with antutu with 100 - 1150 range and everything works well. So will see, what about battery life

it is impossible on my device to set 1100 or 1150 max, always get reboots
(it doesn´t matter which gov and sched i use)
the kernel works without problems on 100 - 1000, but the responsibility isn´t as good as on builtin kernel (depends on the min freq 100).
very pity that i can´t test this kernel with oc freqs
@Fred6681 btw keep up this good work for all other users

But at PAC-performance we have an extra point at cpu. There you can set how aggressive the decision should be to turn second core off
This is a kernel feature at tenshi-xp's kernel, at your kernel it's not shown... maybe you could ask him what exactly it is.
It is a really nice feature...
Have fun!

Hi Guys After Flashing Some Custom Kernels I've Found Some Kernels Support Adreno Boost
Kernels Support Adreno Boost:
- Shadow Kernel
- Sphinx Kernel
- MLX Kernel (Removed)
That's It For Now But I Don't Know If More Other Custom Kernel Support It
Now The Point Is What Is The Function Of Adreno Boost? What Does It Do To The GPU? CPU? I Don't Know ! The Only Explanation I Get From Kernel Managers Is "An Add-On Developed By flar2 For msm-adreno-tz GPU Governor On Qualcomm Adreno GPU"
It makes adreno tz ramp up GPU clock speed faster

Nice Kernel!!!
Could you add Spectrum support in your Kernel?
Hi, I flashed the kernel in the new OneUI 2.0 Android 10 and it caused bootloop, I tried the other kernel and it didn't work too. My device is A600G with latest Android 10 build.
Edit: Sorry the problem is not the kernel I tried to flash only TWRP and got bootloop again.

I see. That's why u are trying different kernel. I just got back to android 9 because i can't stand the lag. Luckily they got the same Bootloader so downgrade is possible. Will not upgrade to Q unless the lag is fixed.
there is a new version, RC13 still works with Pie OneUI. Meanwhile 13.1 is only for Q OneUI
And RC14 oneui is only for android 10 right?

deepsleep over sleep
Every 1 minute screen off then the phone going to freeze and must force shut down (vol down + power).
Idk this bug from kernel or just from my gsi
Edit : the problem is from kraken kernel not gsi.. Solve by installing coronos kernel v5 and my phone stable now..
I hope kraken fix it for next update

Hi all,
this is the thread for a custom kernel i made for Samsung Galaxy A20 and A20e
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 A20 and A20e. On creating this kernel, I believed that 1 kernel can be all of the above if properly tweaked!
As from Eureka R9.0, four kernel variants are available inside 1 same zip. This has been made possible using AROMA Installer.
Compatibility:
This kernel is compatible with AOSP GSIs/ROMs, OneUI2 and OneUI3. As from R9.0, there is only 2 variants of zip to download. One is called EMS and the other one is called HMP. Continue reading to learn more about them.
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 zstd.
* 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 4.4.302
* Built with Vortex Clang 14 toolchain with LTO. Reason: Better performance
* Support for EMS (Exynos Mobile Scheduler) added
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.
We have developed our own kernel manager called EKManager which is a fork of HkTweaks. It is compatible only with Eureka Kernels. You can download it from here:

Reference about EMS kernel:
Energy Aware Scheduling (EAS) gives the scheduler the ability to predict the impact of its decisions on the energy consumed by CPUs. EAS relies on an Energy Model (EM) of the CPUs to select an energy efficient CPU for each task. Allowing to save up battery even further. EMS aka Exynos Mobile Scheduler, is a fork of EAS for Exynos. We ported to our 4.4.y kernel. As written above, EMS kernel is good for battery saving. Some words from kernel official docs: - EAS operates only on heterogeneous CPU topologies (such as Arm big.LITTLE) because this is where the potential for saving energy through scheduling is the highest.
EMS kernel + pwrutilx governor is very good at battery saving according to our test.
Reference about HMP kernel:
It's just the stock scheduler that comes with stock kernel. Basically it's the normal kernel.
What kernel variant to flash once inside AROMA installer?
1) AOSP Legacy Q/R/S - If you are using an old Eureka ROM which was released before February 2022, choose this.
2) AOSP Q/R/S (New) - If you are using an Eureka ROM built as from February 2022, choose this.
3) OneUI 2 - For any OneUI 2 roms (stock/ports).
4) OneUI 3 - For any OneUI 3 roms (stock/ports).

I not that great with OP to know if this work will work with my phone the A20 205U and I get nevious with changing clock speed and having to tweak them later?

This kernel has been tested by various A20 users. It should work on your device too. The kernel is pre-rooted with magisk 20.4
If you are facing issues, use the guide provided by Physwizz above.
You dont have to worry about changing clock speeds because they have been tested and they are stable. Only the 2184 MHz frequency gives random reboot on some A20.

I'm keen to give this kernel a go. What version do I use if I am using the Ultimate Q S20 ROM?

Hi all,
this is the thread for a custom kernel i made for Samsung Galaxy A20 based on android Q (10).
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 for A20.
Compatibility:
This kernel has 2 versions. One version works only on ONE UI (can be stock or debloated ONE UI) and the other version works on GSIs and custom roms (GSIs built specifically for A20). So, please download the correct version.
FEATURES:
* Disabled Samsung security features
* Enabled all governors except Schedutils governor.
* 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 728 MHz to 312 MHz.
LIL Cores: from 449 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.
* 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
* FOR GSI:
* Fixed ADB and MTP.
* Set SElinux as permissive
Please read the changelog for full list of changes.
KNOWN ISSUES:
* Random reboots when device is forced to run at 2184 MHz
SOME MINOR TWEAKS FOR BEST GPU PERFORMANCE:
* Set GPU power policy to "always on"
* Set GPU governor to "static"
* Set min and max GPU frequency to 1300 MHz
* Disable GPU thermal manager to prevent GPU frequency from dropping
* If you are on ONE UI and GPU keeps on changing when u force it at 1300 MHz, disable/remove devicehealthmanagerservice and gameoptimizingservice apps
* 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.

Ultimate Q is debloated ONE UI
So use the ONE UI version.

Magisk manager is an app which controls root access
Magisk 20.4 is the latest root
Your download is probably corrupted. Slow internet can corrupt files.
Download it again and flash via twrp.

Thank you. I appreciate the work.
great work :good: MTP works great
When I have Quantum V2 kernel running I have the 'Advanced settings' option in Display > Full screen apps to hide the camera cut out.
When I install this kernel the option disappears.
Is this normal? Any way to fix?
Thanks.

It will not work on the U models.
We have a locked bootloader.
R4.1 works nice

So the U model just comes from metro I did ask via phone call if I can unroot my phone legally as they said yes but they would not do it so I wish I could sue metro for lying I all I said was it was a galaxy

A205u is the north American universal device.
You can unroot your device, They cannot unroot it for you, because you literally voided your warranty.
You are liable for any and all changes that you make to your device. Only you. Nobody else.

I don't know about this issue
No one reported that before.
I don't know how is this feature related to kernel.
I'm on A10 using Eureka and these options are still there for me tho.

Thank you. I might try doing a full wipe and installing.
Is it working for Samsung SM-A205GN. I tried it in my SM-A205GN but the max frequency is 1560Mhz my phone is rooted and the gpu has 1300Mhz but GPU Mhz only reach 676Mhz
