Hey!
First time using agni kernel on Nougat NOS rom, can someone please tell me best settings for balance performance? Like no lag, smooth but good battery backup?
Never used this kernel, only radon and still lag sometimes with balanced settings.
Thanks! Appreciate all info!
According to Agni dev, kernel will improve with time, I am also using Nitrogen with Agni, and I also experienced lags on first day. Wait for a full day of use, and don't turn your device off. It should improve.

Use this settings:
In Agni control all cpu Freq. To lowest ( MINIMUM and MAXIMUM both do it low Freq)
Big governer interactive glassfish, small governer interactive glassfish.
Hotplug - intelliplug
GPU Freq. To lowest in Agni control.
Lz4 zram off for 3gb ram and If 2gb ram variant then Lz4 zram 256 set.
Adreno idler on
In spectrum app, set profile to battery.
Last one can be ignored outdoor since it dims brightness.
Then save your current setting. and Reboot.
If it lags for you in beginning don't worry.
It will adapt your usage and it will be smooth the more you use.
Try this :-
Governor big cluster- Interactive glassfish
Governor small cluster- Interactive glassfish
CPU Max freq big cluster - 1612
CPU Max freq little cluster- 1382
CPU Min freq big cluster- default
CPU Min freq little cluster- default.
CPU hotplugging - Intelliplug
GPU Max freq- 550
GPU Min freq- 133
Adreno Idler - On
Z4 RAM - 500 mb
Rest all default.

MODEM
The modem act as the Software bridge between the RIL driver and your phones Hardware (correct me if i am wrong)
Because of that you can directly (more or less) control how your phone signal is behaving by trying different Modems till you find one that suits your needs.
The modem images does have an impact on wifi, mobile networks and how fast they are able to scale up or down, battery runtime, as well as call quality sometimes.
While the g3 got a good signal most of the time the changes might not be this big, compared to other phones and their modem differences, but it is still a good thing to know you got the best reception possible
For me the 20A and 20p Modems are working better then the most others... But there will be people with other carriers etc for whose another might be the right!

Introduction
This is a kernel for XT1572/XT1575 built from stock sources (marshmallow-6.0.0-release branch) with cherry picks from other kernels and some ports/mods done by me. It started as a personal build tailored to my preferences but just thought I'd share in case somebody might find it useful. My main goal is building the smoothest kernel I can get so performance is top priority.
This kernel is for stock ROM MPH24.49-18*
Disclaimer
Although I have experience with Linux kernels on desktops and servers this is my first Android kernel. I've been running this kernel on my XT1572 for a few days and seems pretty stable but that doesn't mean it's risk free. In fact I wouldn't dare to install it if you don't have a proper backup and some basic skills to deal with unexpected situations.

Installation instructions
Download ZIP and flash from TWRP/Flashify. Read the following notes carefully before flashing.
Important notes:
This kernel is still experimental, make a proper backup first
You need to be rooted
DO NOT play with DT2W/S2W before reading the release notes and the update
In case you want to tune some parameters (ie: CPU frecuencies) I recommend you install EX Kernel Manager, Kernel Adiutor or Kernel Adiutor-Mod.
If you're using Kernel Adiutor to control vibration or TCP congestion read this.
Questions? Read the FAQ before posting.

Donations
Although quite a deal of the important work has been done by the developers mentioned in the Credits section I spend many hours working on this. If you feel like helping me out I'd appreciate some tiny donations to cover some minor expenses.
Thanks to all of you who have donated, it's very much appreciated.
Profiles
One of the FAQ in most kernel related threads is "What are the best settings for .....?". This is the 10 million question since the usage pattern can be very different for each user. However, I understand less experienced users will appreciate some hints in this department, so that's why I'm posting some basic settings you can use as a starting point.
It's your job to further tune them to suit your needs. You should be able to modify these settings with whatever Kernel Control App you like the best, although not all settings are available in every app, in such a case tune those you can. The list is not complete (just the most importante settings) and is loosely based on Kernel Adiutor arrangement.
Please, keep in mind these are subjective values (based of personal preferences or popularity) and some people might like other settings for whatever reasons.

FAQ
I get random reboots, what is happening?
This kernel overclocks both clusters by default (a53: 1536MHz a57:2016MHz) and although this is very safe for most devices some CPUs are in the lowest spot of the binning spectrum and can't handle O/C very well. In such a case use a kernel control app (see the OP for references) to limit the maximum CPU frequencies, play with them until you find stable values for your device.
What are the best settings for battery life/performance/whatever?
That's hard to tell as every user is different. You can find some basic profiles in the OP you can use as a starting point. Notice the differences between then and build you own.
Why do some BIG cluster settings display N/A?
Why can't I change some settings on the BIG cluster?
If you get N/A or weird values when trying to change settings on BIG cores it means both are offline ("hotunplugged"). To work around this select "performance" governor, make your desired changes and then select you previous governor. You can also disable hotplug, make the changes, and enable hotplug again.
DoubleTap2Wake doesn't work sometimes. How can I get it to work all the time?
When device goes into suspend mode first tap is often missed (I suspect this is caused by Moto Sensor Hub). If you tap three times and get the timing right you'll probably make it work most of the time. As an alternative, Sweep2Wake works almost all the time
DT2W/S2W is acting weird or disabling itself
Make sure Moto Display is disabled. Open the Moto app, click on the stars in the top right corner, select Display and set to Off
Can I use this kernel in ROM X/Y/Z?
This is for stock ROM MPH24.49-18 only. It'll probably work on any stock based ROM but not guaranteed.
I use stock ROM but WiFi is not working
Due to some internal changes all modules had to be recompiled (WiFi included). In order to expose the new modules without modifying the system partition I had to implement a hack that requires root. Make sure you're properly rooted.
What's the deal with ZRAM?
ZRAM is a technique to increase memory available to the apps at the expense of CPU time. Memory space from apps not being used is compressed into a memory swap area and uncompressed on the fly whenever needed. As you can imagine this compress/uncompress process burns CPU cycles, potentially leading to worse battery life, lag and higher temperatures. Since this device comes with 3GB I can only think of one scenario where ZRAM can be beneficial: heavy multitaskers who care more about apps not reloading than battery life. For the rest of users enabling ZRAM doesn't make much sense in my opinion, and that's why it's disabled by default.
UPDATE: v0.10 includes an updated ZRAM driver that improves performance significantly. So much so that the benefits seem to outweigh the costs and it's been enabled by default.
What's the deal with KSM/UKSM?
Since many apps use the same libraries/resources it's very likely that at any given time there are multiple copies of the same data on different memory locations. KSM/UKSM tries to take advantage of that fact by scanning memory pages periodically and consolidating that multiple copies into a single shared copy. Much as like ZRAM it can have a good effect on heavy multitasking performance but at the expense of CPU cycles, and thus it's only recommended in the same scenario as ZRAM. Disabled by default
Ok, so do I enable ZRAM/KSM/both/neither?
I honestly think most users will be better off not using neither. If you feel like you need extra RAM I'd try KSM first, then ZRAM. Using both at the same time is overkill unless you are an ultra multitasker, in which case you should probably get a 4GB device anyway
How do I get WiFi on 6.0.1?
It's a modem version mismatch issue, you need to downgrade the modem. See this post.
Love to see more options! Thanks for sharing!!
Yeah this will be very good
Only One think that would be awesome try to implement the double tap to wake
Awesome! More custom kernels are always welcome are there many governors to choose from?

As I said on the OP my main goal is performance/smoothness, so I haven't specifically sought better battery life. That being said I'm getting about the same battery life as stock with better performance, that works for me.
Nevertheless, I'm very interested on how it works for other configurations and usage patterns.
@dirtyhank could you please add hotplugging to the kernel? Preferably one that allows you to select how many cores to run as well as which ones, as in run the two A57s and turn off the four A53s. Currently I'm running two A53s at 1.2Ghz and the remaining four cores are always off.
The screenshot is from Lolipop, and it is the only reason why I havent upgraded to MM. Turning off cores definitely makes a difference on battery life.
Also, if possible, adding a lower speed to the min speed. Will gladly test anything you thow my way. Thanks in advance.
Is there any chance for a CM13 version and a DT2W fork from elementalx?

DT2W maybe, CM13 unlikely.
very nice thank you! slowly slowly we getting more and more things. Just making sure this is only for stock based rom/s Thanks!!

Getting bootloop on TruePure rom 2.4. Anything I can try to avoid bootloops?
What is the best settings in Kernel Auditor for battery life?, im using the latest RR
Same here.
CPU / GPU frequencies on minimum with powersaving CPU governor, there u go best battery life.
So I've been hearing Schedutil is the most balanced governor for Android phones cause it can handle battery and performance well.I searched it on internet and found some article about it that my brain can't understand.
Why is it better and how it works? Can anybody explain it to me or provide me some link where I can read about it?
Thank You
It's a CPU governor. Look inside here. This governor requires Linux kernel 4.7+.
I got problem with schedutil on oneplus 9, its the default governor and get low fps while gaming. Maybe is a bug with "games" app what should change to a better governor while gaming... it also have a "performance" option
This governor is quiet ****. Its like ondemand ramping up to max clock when not needed.
There are so many questions asked over and over again about how to configure the kernel for a desired outcome..... max performance, best battery holdup, fix freezing etc.
I will post this for those who did not attend school just for the bus ride or playtime. All dumb questions ignored so if I don't respond, you asked a dumb question or made a dumb comment.
We have a choice of 1 custom kernel (Eureka) that can be comprehensively tweaked thanks to many of the settings being moved into the DTB partition. Currently, there are 20 versions of the DTB image that can be selected on kernel installation - 10 enforcing and 10 permissive with 10 different mixes of cpu and gpu frequencies to suit most needs. The default sets everything to maximum and is the cause of the majority of freezing / crashing on an A205 phone that has a lower quality SoC than the other A series compatible phones. Most will end up using DTB2 to fix instability but even this might not be enough. You then have to consider a lower frequency DTB which lessens the attractiveness of using this custom kernel. Why not make your own flavor of DTB that can more accurately reflect what you can run on your specific SoC? Here's how:
Open up the Eureka Kenel zip file in whatever zip extractor you use.
Extract DTB2.img from the zip file (either permissive or enforcing version depending on what your chosen ROM needs)
Now open DTB2.img using a hex editor
Now look at the following which is a list of addresses (in hex), what the value at this address is defining and a list of possible settings. Frequencies are in MHz and the hex code to set it is the frequency in kHz example: 343MHz is 343000kHz, 053BD8 is hex for 343000.

First thing: The default min freq of 208MHz does not save any more battery than setting this to 343MHz (for small cpus) and 312MHz for bigs.
Next thing: The A205 more than likely will become unstable at anything above 2080MHz for the big cpus but can probably cope with 1794MHz on the small cpus. Each SoC is slightly different so you must test what your phone can handle, not what someone else's phone can do!
Next: It is highly unlikely that your A205 will be stable with the GPU maxxing out at 1300MHz. You will not be aware of this until the gpu governor actually cranks the gpu up to that frequency i.e. you can remain oblivious to it for some time and incorrectly assume something else is causing freezes / crashes / glitching.
Next: There are many more settings in the DTB relating to boost frequencies on various input conditions i.e. screen touches, keyboard clicks, mouse clicks etc. Most of these are set to peak at 1144MHz which seems quite reasonable so I have not sought to specifically identify and edit these.
Edit: So here are the input boost frequencies: (address, name, function, freqs)
I assume the first addresses in each block are for BIGS and the 2nd lot are for SMALLS. It seems to work well to set all the BIG freqs to 936 and all the SMALLS to 839 since there is an abundance of upward boosting from other sources such as the Governor and Exynos specific drivers.

Recommendations:
Min Freqs:
Set GPU to 343MHz, small CPUs to 343MHz and big CPUs to 312MHz. This is the maximum power saving you will get and offer minimal lag as the frequencies scale up to meet demand.
Set the GPU max freq to 845MHz while you are establishing what is stable for the CPUs.
Set GPU boost to 545 or 676MHz (depending on your compromise between battery and performance)
Set GPU boost load trigger level from the stock 75% down to 50~60%. Again depending on your compromise between battery and performance. Lowering this setting has a significant impact on reducing perceived lag so the stock setting was probably far to high.
Set big CPU max freq down to 2080MHz. This solves most crashing that is due to the cpu being overclocked too far.
Set small CPU max freq to 1794MHz unless your SoC proves to be unstable at this.
Set the CPU boost freqs to something quite low (around 700~900MHz). There are other boosts that override this basic CPU boost freq so you will almost never see it.
Note: If you want maximum battery savings, setting the max freqs lower seems like a logical thing to do but it is not! If you halve the cpu freqs, you double the amount of time they must remain on but you do not halve the power consumption so you end up consuming more power....
Make the changes and save the DTB.img file and flash it in recovery to DTB partition and reboot.
Install hKtweaks_v2.2.2 or your favorite kernel tweaker that can deal with Exynos SoCs (not many can)
Take a look at the cpu and gpu settings to confirm that your edited DTB file is producing the expected results i.e. min and max freqs agree with what you set.
You are done!
Err..... only kidding there is more to do.
Now back to the issue of the GPU max freq. In hKtweaks you can override the settings inherited from the DTB (within the limits set by the DTB). The max GPU freq is also associated with a core voltage. Lowering the voltages will make the GPU run cooler (use less power) but also it will not overclock as far as if the voltage is higher. Here is the dangerous bit - you can increase the voltage to make it overclock higher but cause it to overheat quicker which will make it throttle back to a lower freq. There is also an error in the DTB: Look at the settings for throttling the frequency back at certain temps. Set GPU LEVEL 3 Throttling Freq to 343MHz to fix the error.
Have a play with the GPU settings in hKtweaks without setting Apply on boot so if you set something that crashes the phone, it will revert to normal on a reboot. When you are positive you have the best GPU settings. then set Apply on boot.
Now you are done!
Err..... not quite, there is more.
O.K, assuming you have your custom DTB set up exactly how you want it, it is time to look at some important settings available through hKTweaks.
Firstly we will look at the CPU Governor selection. Interactive is the stock setting and if you watch what the CPU cores are doing with no background activities (kill all unnecessary apps), you will see the frequencies will be dancing around without settling down to the minimum freqs. This is partly due to a dodgy implementation of this governor by Samsung and also the excessive amount of invisible running services that allow Samsung and Google to plunder your personal data in realtime.
Touch the screen, scoll the screen etc. and you will see the various CPU boost features adding to the overall freqs.
The Eureka kernel has extra CPU Governors added - not all function correctly... be warned. Some Governors apply to all CPUs (big and small) and can't be configured separately. Some Governors can have separate configurations for big and smalls.
The way this works is whatever is set for cpu0 is applied to all smalls (cpu0~5) and whatever is set for cpu6 is set for all bigs (cpu6~7).
In a root filemanager, take a look at /sys/devices/system/cpu/cpufreq If you see a folder with the Governor's name, the Governor is applied to all cpus big and small with the same settings. If the Governor does not have a folder here, look in policy0 and policy6 folders. If the Governor has folders in there, the Governor can have separate settings for big and smalls. This is determined by however the Governor was set up at the kernel level.
I can't tell you what Governor is best for your usage patterns - I have already warned you that some are borked so all you can do is try them all while watching their behavior. until you find one that works for you.
Let's use Smartmax as an example. It is not aware of bigs and smalls so any settings are applied to all cpus. If you set this Governor for both big and small cpus, changing the settings in big will change the settings in small as well. The default settings will automatically pick up on the settings you made in your DTB. The remaining settings are not bad as they are but can be improved on.
Try it out, set Smatmax as the governor both both big and small and observe the cpu freqs on idle and when touching / wiggling the screen. You should see it scale up rapidly and scale down to min freqs much better than Interactive was doing. Have a play with other settings if you want - I tend to speed up the ramp down rate and increase the ramp down step to make the cpus return to min freq quicker (for battery saving). Once you have experimented with Smartmax, have a play with the remaining Governors to see if there is anything you like. Something I learnt from a previous phone with a MTK octa core SoC is that there is no power penalty for readily scaling the cpus up to a (sensible) maximum freq. This gives the phone a fast, lag free feel that everyone wants and the cpu will complete its tasks faster so it can return to idle faster. A foolish overclock freq will burn more power - usually when the core voltage is cranked up stupidly high to get the overclock - bad for phone, bad for battery! A bad Governor setup will chew battery if it doesn't pull the frequencies back to idle at low loads but view this in light of the amount of background services you are running. MyAndroidTools is an excellent app to view and take control of pesky services.
The GPU also has a choice of Governors but I recommend sticking with the default Interactive. You get to choose the GPU Highspeed freq and load and both of these settings can be embedded in your DTB. Play with the freq / voltage tables at your own risk!
More to come....

If you want to know which CPU, GPU governors are best and what the difference is between them, there is loads of information already gathered on this topic. Most of it is quite dated but still relevant. Here is a good starting point:

There is a lot of misunderstanding on Eureka Kernel and ROM forums around the issue of memory management - LMK, Virtual Memory etc. Many users want something for nothing like running every known Samsung, Google and Social Media app in the background on a A12.1 or 13 ROM on a phone with 3GB RAM.
The basics of virtual memory have not changed - set ZRAM to no more than 50% of the available memory and set ZSWAP Memory pool to no more than 30%. Swappiness is best at 100% and vfs_cache_pressure set to 50. These settings are the favorite targets for abuse in tweaks offered by people of little knowledge.
Once you have your virtual memory sorted and have made smart decisions on what services/apps you are going to allow to self start on boot and hide in the background, it is a simple case of looking at the free memory to figure out how many more apps can run before killing occurs. It should surprise no-one when it occurs..... blame yourself, not the kernel, not the ROM, but your decisions on what you run and how you configure the phone.......
