got hard reboot on test 1 kernel stock while mobile was charging.. ( I am not a technical expert I exported this using your demo app I can't read logs.. I don't know whether it's right or not)
[Samsung Galaxy S8 & S8+ Cross Device Development] traversone:
it seems the latest "test1" version shows some regression in terms of stability (my benchmark is AndroidAuto as usual) but of performances too without changing anything in settings.

Then....I reverted back to June 3rd version!
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
What happened ? Without logs i can't optimize anything.
[Samsung Galaxy S8 & S8+ Cross Device Development] traversone:
no reboot in 3 working hours but the feeling is that mobile runs slower (balanced profile always set).

on AA side, as in all previous (unstable) releases, the 1st time I connected the mobile to HU, nothing happened (AA interfaces does not load at all) and after USB disconnection mobile was frozen for allmost 20 seconds with no reaction to user's input
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
the new release battery durability justgot 3hour but i am not charge this phone in this day have good at background
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
When we get it stable everyone that helped with debugging can send me a pm with request for full version free code. If you pass my requirements i'll answer with the code.
[Samsung Galaxy S8 & S8+ Cross Device Development] Trasher29:
Yeah, most of the times the reboots happen shortly after I put the phone charging. I can't say if it's caused by wireless charging, I rarely use the wired connection for it. My phone often heats up pretty hard while charging, even if it's fully charged with the charging limit set to 95%.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@ up

because it doesn't stop charging at 95 %, it means at 95 % it'll switch to "battery idle mode", i.e. it keeps powering the phone over charger not battery.

Maybe i'll update Charger Control and add option to stop charging instead to switch to battery idle mode.

btw: test1 kernel is a test kernel for the zRam random reboots, it's not there for testing battery life or speed.

Anyway: if it's too much annoying you could try to tweak the HMP driver over scripts / init.d like that:

cd /sys/kernel/hmp
echo 64 > up_threshold
echo 64 > sb_up_threshold
echo 16 > down_threshold
echo 16 > sb_down_threshold

In the end I could not resist repairing my beloved S8, I took the original service pack with full lcd and as soon as I have time I will personally try the replacement so well, it will be back soon as a forklift for testing with A2N (hopefully) 👍😂🤙
[Samsung Galaxy S8 & S8+ Cross Device Development] lmegogol:
Hello, I installed the kernel on my s8 again. i did everything according to the instructions from the post, the camera started, but after installing the magisk as an app it does not work. and reboots again.
[Samsung Galaxy S8 & S8+ Cross Device Development] macleo:
What is the best settings for A2N kernel for gaming performance, without the over heating it while playing?
[Samsung Galaxy S8 & S8+ Cross Device Development] Devil90:
You can try with oc Cpu 2.5Ghz big and 1.9Ghz little and Gpu 572mhz, you could also lower Up threshold for Cpu / Gpu , the important thing and don't touch Dvfs.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
If you want not get over heating you will not receive good performance HOT=more performance if dvfs increse cold = less performance that will be affected if your room temp is 25-35°C
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
How to tweak it? To get good HMP? If too high what happen and too low what happen?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Range is 1 - 1024 but down threshold must be at least the half from up threshold. Like always smaller value for thresholds is for better speed ... means more aggressive task migration to the big cpu. High value will make the phone very slow.

The values i've posted are good for speed.
[Samsung Galaxy S8 & S8+ Cross Device Development] lmegogol:
so, when i installed your kernel should I uninstall game.gos, game launcher and etc? or your kernel is working good with this ****ing apps? so, i think all problems with camera with klms agent... but now I reinstall your kernel and I hope this is because of this klms agent...
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I don't use game launcher etc...

Nobody need such a BS.

Hi Dev.....can u support note 8 pls?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hi Noxx, it was with your latest Source code for Android Pie:

https://github.com/Noxxxious/Upgrade

Also checked Ramdisk, nothing unusual that could ever cause such issues with Mali Driver.

I suspect it's caused by installer ... maybe i'm missing one Patch ?

Kernel default is not tuned for the best battery lifetime .. it's tuned to run smooth, but still trying to save as much as poossible battery.

So if u want more battery, u've to increase "up_threshold" for both clusters ... the higher the value the more powersaving u'll have.

But that's not all, wait for App Update, then u can decrease input booster Freq .. then it should be better than stock ... but u can forget about smooth phone.

FAST CHARGE is disabled by default !! it set @ 1200 mA default. (because it saves 3°C lesser Heating during charging ... even using thr same charging current!) So u've to enable it in the App. (but better is to increase only charging current instead to enable AFC ... due to less heat !! ) If u've the original AC Charger .. it can handle up to 2200 mA without fast-charging enabled ! only enable AFC if u need MORE than 2000 mA !

No difference at all ? ok thanks, i'll check it later ;)

Thanks for last_kmsg .. i'll check later ...

Really ? So if we flash first RZ Kernel then A2N Kernel on top it will work with every Custom ROM here based on Android 9 ??

If so, then it could be a installer issue .. :confused:

Thanks, the best comment so far :D

Yeah i think it's just a little something. ;)

Thanks for your Report ! - So the trick is to flash first the RZ Kernel ? :laugh:

Of course it'll be better, this is only the beginning ... Many things are actually not fully hacked. :o

So u Guys can expect in the future more Speed + Battery for your immortal S8 / S8+ Phone.

I think it's more important to fix first Mali issues :highfive:
[Samsung Galaxy S8 & S8+ Cross Device Development] lataiwan:
I also found the issue from "kernel manager". If A2N kernel last be installed, system will use A2N kernel; in contrast, if RZ kernel be installed at last, system will use RZ kernel.

So... I agree your opinion (saying/view) about above things.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I didn't understand what u mean with kernel manager app ??, sorry.

Of course, that's logic, last kernel will always override the previous flashed kernel, since it's not possible to use 2 kernels at the same time
[Samsung Galaxy S8 & S8+ Cross Device Development] paradoxxman:
weren't you the guy who also made some custom kernel for A5 2016 back then?
[Samsung Galaxy S8 & S8+ Cross Device Development] :
Is not A5 2016 but Ace 2
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Uploaded new Test-Kernel Guys !!

Please test and report if freezes are fixed with the test-kernel uploaded on 28.10.2019 :)

If it will still freeze, pls provide a last_kmsg, otherwise no way to fix.

Download - Test-Kernel
[Samsung Galaxy S8 & S8+ Cross Device Development] Sureshtuty:
Flash test kernel. No freezing & reboot issue. Thanks for ur hardwork:laugh:

Edit - within 4 hours of usage suddenly lost volte, tried rebooting,clearing cache & dalvik. Switched to another kernel & the volte back?. Seems like a kernel issue. Anyone got this same?
[Samsung Galaxy S8 & S8+ Cross Device Development] d_802:
I had installed A2N Kernel on my S8+ Dual SIM yesterday (Using latest Alexndr ROM). It looked ok but when checking this morning it had consumed about 10% battery during the night hours (didn't use it) and suddenly it powered off...i wasn't able to start my device for several minutes, no reaction. And after ~5 mins and retrying Power Button + Vol up several times it started again. Don't know why i had this issue...But now i'm happy that my device isn't broken.

Here are the logs after a crash. Note that in antutu stress test I get a crash with, or without overclocking.View attachment 2019-10-28_15.50.zip

[Samsung Galaxy S8 & S8+ Cross Device Development] lataiwan:
I second this.

It got a crash, when it run antutu testing especially cpu multi-threads and run cpu benchmark of Geekbench 4&5. And it will restart(reboot) by itself.

It maybe conflict with system UI when enter system, navigation column & notification bar & screenshot will lost functions, especially with GravityBox [P] module. And in black background (wallpaper).
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
:good:

Edit - within 4 hours of usage suddenly lost volte, tried rebooting,clearing cache & dalvik. Switched to another kernel & the volte back?. Seems like a kernel issue. Anyone got this same?

Hmm strange ... Next time please do this:

When u face something is goind wrong, then immediately open Kernel Control Demo APP, then in debug menu generate dmesg + logcat.

then reboot and generate last_kmsg.

Instead to force it ON by booting to recovery, it's better for the battery if u just plug the charger cable .. and wait for 5 minutes ... then u can boot normally without to stress the battery.

As for the high battery draining, i don't know exactly for now, but i've noticed that cameraserver service is crashing all the time. so maybe that caused some battery draining. I'll fix it in next build. Otherwise for u, then same i wrote for Sureshtuty about logs.

Thanks for logs + Report ! - Same i wrote for Sureshtuty about logs.

It's better for now to test without OC ... to make sure the crashes are not coming from unstable CPU or too high SoC Temps.

For instance: once the SoC hit 100°C, then it'll immediately reboot in order to prevent overheating the chip. (i've already tested)

But if it's crashing just before to hit 100°C, then something is wrong of course ... i'll test as well with my Phone.

[MENTION=7914525]lataiwan[/MENTION]

Thanks for your Report ! When comparing different Kernels i do suggest to make sure that u follow the following simple rules in order to get a good result:

1. use static CPU Freq . e.g. Cluster 0 min=1690 max=1690 / Cluster 1 min=2314 max=2314

2. disable swap (zram, ksm sswap etc., make sure "free -m" command is showing u "swap" 0 0 0)

3. during the test, don't use the phone at all.

More help:

1 = at this way you will not do cpu governor benchmarking (which is quite useless)

2 = comparing a kernel with swap enabled and the other without, will also make the result invalid.

3 = no comment needed :D

btw: swap is disabled by default on A2N Kernel...
[Samsung Galaxy S8 & S8+ Cross Device Development] lataiwan:
I passed antutu CPU testing just now with a tweak(or fixed).

As the same, I cannot pass antutu 15 mins press testing.

The kernel is a good kernel, but need some fixed/patched to let it better.

How to tweak it? To get good HMP? If too high what happen and too low what happen?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
See post #2381.

Note: only valid for test1 kernel ...

On normal official releases we don't use HMP at all.
[Samsung Galaxy S8 & S8+ Cross Device Development] traversone:
I have a big doubt after an intense AA session in car.

Sometimes the AA connection to the HU is not established (as USB has never been connected) then I checked the Power section in the A2N App: I thus realized that every time I disconnect/reconnect the USB wire, kernel detects a different kind of "charger"...sometimes USB 2.0, sometimes CDP, sometimes PD and sometimes AC...

the bottom line is that battery gets very hot in 4-5 minutes and, even disconnected from USB port in car, temperature still goes on increasing.

thanks for attention
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Report dev test kernel

Random reboot i curious about my youtube vance make it random reboot mah you can check it

.

Edit

My settings is default i use init.d and use ussualy code doean't work and i check direct to the file it changed but back to stock again and again
[Samsung Galaxy S8 & S8+ Cross Device Development] Trasher29:
Got a reboot running kernel test1, I think it was in standby, phone was in my pocket.

Profile: balanced

Disabled boost
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Battery idle check: screen off, blue led is on.
[Samsung Galaxy S8 & S8+ Cross Device Development] macleo:
Upon battery idle check, this will apply the settings already or I need to wait for about a minute or so, or need to restart the phone?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
When you enable battery idle and on screen off you see the blue led then it's active. No reboot required.
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
recommended HMP settings for good performance:

up threshold to 64

down threshold to 16

and yeah if you have full version app set lower value as 1800 mhz for suspended frequency. As it will not drain your battery when mobile screen is off when its in pocket or during night..
[Samsung Galaxy S8 & S8+ Cross Device Development] traversone:
sorry Pranil60...I got lost!

where are these 2 settings? are they % ? I have just flashed test1 latest version
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
use these commands in init.d script:

cd /sys/kernel/hmp

echo 64 > up_threshold

echo 64 > sb_up_threshold

echo 16 > down_threshold

echo 16 > sb_down_threshold
[Samsung Galaxy S8 & S8+ Cross Device Development] macleo:
Thank you
[Samsung Galaxy S8 & S8+ Cross Device Development] macleo:
Where I could find the up threshold and down threshold settings? and where do I set the 1800mhz is it at the BIG CPU or LITTLE CPU?
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
using any root browser open file init.d script having location

system/etc/init.d/99_user

and yeah you need to open in as tect file then at open space paste these lines or command whatever you call it:

"cd /sys/kernel/hmp

echo 64 > up_threshold

echo 64 > sb_up_threshold

echo 16 > down_threshold

echo 16 > sb_down_threshold"

it's for big cpu for small cpu use even smaller suspended frequency
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
BTW use test 1 kernel as dev had posted in recent post.. it's so stable and smooth got no reboots at all in hades rom.

and it would also help to dev for debugging and making even more stable kernel if in any case you get reboots just right after reboot using A2N app.. clicking three dots at right upper corner then debug then generate lastkmgs and logcat.. you will get these files in main storage directly.. then post those files here.

IF ANYONE NEW HERE PLZ NOTE ABOVE...
[Samsung Galaxy S8 & S8+ Cross Device Development] macleo:
I wanna ask, if i forgot to turn off the battery idle, then accidentally my battery runs out of juice, does my phone will still power on since it is powering it via usb cable, or it will just charge my battery?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
If you set charge current to the max and use a powerful charger then battery should stay at the same level.

All settings you set in a2n app are not valid if you charge in LPM (phone shutdown)
[Samsung Galaxy S8 & S8+ Cross Device Development] macleo:
Thank you, it helps a lot
[Samsung Galaxy S8 & S8+ Cross Device Development] Aminewolf:
Very snappy, but my s8+ heats up more than with other kernels... my external battery isn't fast charging the phone anymore... also, phone reboots out of nowhere several times a day ... latest 03/06 and same with previous version. Can't even test different settings cuz there's no trial on the app (which is weird) for something like a custom kernel... is there a way to test the app before buying?
[Samsung Galaxy S8 & S8+ Cross Device Development] Trasher29:
Got a random reboot while charging.

Profile balanced, disabled boost.

I would like to highlight some confirmed behaviour in the Battery Charging function.

Despite the default 40° setting as max battery temperature, in CDP mode kernel continues charging battery ad nominal level (2000mA) and temperature gets 48° and maybe more...

So, when can we expect an update? in what time frame?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No idea, actually it's too warm here. Maybe i should build an air conditioner instead to build kernels lol. Also i've to update my lubuntu distro from 12.04 to the latest version.

After that i'm able to continue the work here.
[Samsung Galaxy S8 & S8+ Cross Device Development] lmegogol:

[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes bro i believe what you say but then it's an issue with your phone, nothing to do with this kernel. So no need to spam the thread with your personal issues. Try to fix it, you will manage this.

May I ask...I have the A2N Kernel running perfecly, If I am going to use magisk modules like L Speed, GPU Turbo Speed and the likes, is there a significant boost on S8 or it wont?
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
Any news dev??
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hi, i think you deserve it, but for now it's useless, we need to make it stable, then you can ask over pm.

No, not compatible at all, don't flash any optmizationsscripts from magisk modules or else, most of them will modify your phone without the ability to revert things back to original. Of course if you do first a full backup of /system and /data, then later you could restore it back.

I say that because i saw source code on GitHub about such Magisk modules and it's horrible how much the system will be manipulated for no reason. And for the last one: the developer from such modules didn't test at all how it behaves on the real device. Most of them are universal and they just apply countless of settings to every device without to test if it works better.

Not much for now, here is summer, during summertime development is very low or paused.
[Samsung Galaxy S8 & S8+ Cross Device Development] macleo:
Thank's for your advice, and it really makes sense.
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
Ofc it's a summertime but many ppl we got problem with reboots..What is solution for this??
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
You can try if it's better with zram 0% or try other kernel like RZ kernel or stock kernel from my FTP server. Then later when you see a new A2N release, you can go back to this kernel if you liked it better.
