Yeah that what i said at first update of DVFS of this kernel i was think same like you but one aplication change my mind the app is CPU thermal throttling test search it on play store and i see the app and turn on temprature i see some thermal sensor is for 4core big cpu have same thermal and 4core little have 4 diffrent thermal 1 for battery and 3 is for little core

And the reason why in cpu float is peak like 65°C because the thermal sensor is the closest from big core and the cpu float read it because that cpu float peak at 65°C or else
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
There are a lot of temp sensors .. not only 3.

Anyway, because CPU/GPU are very closely, the big CPU heats up the GPU and vice versa.

Anyway, when you guys runs CPU-only bench/heat tests, and you see only something like 65 °C, then the app reads the wrong sensor ... it's very likely GPU sensor instead of CPU sensor.

Edit: little CPU sensor is even not exported to userspace at all, because its Temp is not critical at all.

That means it can run at max_freq 100 % load without to cause Temp above 75 °C.

my bunning is cpucl0 = 7 cpucl1 = 7, I don't know very well what it means, the more the higher this bunning is, the higher it is to increase the frequency?
[Samsung Galaxy S8 & S8+ Cross Device Development] Trasher29:
I've got two more logs from the previous version if your interested. My alarm didn't go off today, when I woke up and woke up my phone it didn't really respond I couldn't use the side swipe out panel and was really laggy. The time was displayed correctly. It was plugged in before. Few seconds after, it restarted and optimized the apps again. The second reboot happened shortly after I woke it up.

Yesterday I charged the S8 over night with a wireless charger, limit 95%. When I picked it up it was really warm, the whole phone had the set temperature limit of ~40°C from the app. This already happened a few months before.

What could be the cause of that?
[Samsung Galaxy S8 & S8+ Cross Device Development] Devil90:
It indicates the quality of the chip, the higher it is and the better the voltage should be optimized, however even if yours is high, it does not mean that you can manage the maximum oc frequencies.

Give it a try with Big 2.8Ghz and LITTLE 2.0Ghz and see if it is stable for you.
[Samsung Galaxy S8 & S8+ Cross Device Development] Luiz2004:
my restart if I put in big 2.8ghz how much LITTLE 2.0ghz too

HI everyone,

apologies upfront, I may ask a stupid or already solved question. But I wasnt able to find the solution yet.

I just flashed the Alexis-Rom (latest version 9.2.1), afterwards A2N Kernel. Now Magisk is lost.

The instruction says I have to flash Magisk through TWRP. But I am not sure how to do this with the latest version.

Hope someone can help?

Thanks

Alex
[Samsung Galaxy S8 & S8+ Cross Device Development] Trasher29:
You have to replace .apk with .zip then you can flash it with twrp. Link - Custom recovery
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
For root you will be lose it you must download magisk.zip whatever you want the version but not all version is good for good you can use magisk 20.4 .zip i use that version for updated you can use magisk ver 22 or 21 just search magisk .zip and flash it done

Okay thank you all for the logs !

I'll check them and trying to understand what's wrong.

It can take some time.

I think i've enough logs now, not needed to post furthermore logs.

But you could post logs if it'll still reboot even with zram 0 %.

wow, i check on galaxy ace 2 have 800mhz GPU i hope this samsung s8 and S8+ can be 839mhz too that was amazing work on galaxy ace 2 and undervolt on that wow i hope soon as possible can make on S8&s8+

btw dev since install i only got 1 random reboot but i forgot make the log because not too disturb
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
OFFTOPIC:

hehe.. do you have Galaxy Ace 2 too ? - Stock GPU Freq was 400 MHz and with the max overvolting the hardware can give it was possible to run it stable at 700 - 750 MHz for GPU. At 800 MHz i've graphical glitches, but well that's the double speed lol.

Funny thing, GPU clock has not any limit, i could set it even at real 3 GHz, but it never would work stable due to voltage limitation from hardware voltage regulator.

And CPU stock 800 MHz and worked stable up to 1250 MHz, and for one guy it worked even stable at 1300 MHz. And RAM OC from 800 @ 1000 MHz stable even without the need to increase voltage.

That was good old times, hehe.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I not have the phone but that was legend oc old device and the device have comeback again after comeback again got beated again but that gold like i use Advan i5E i hope that story could be happen again for S8&S8+
[Samsung Galaxy S8 & S8+ Cross Device Development] Devil90:
It makes me want to get an Ace 2, used only for the desire to try your kernel. :cool:
[Samsung Galaxy S8 & S8+ Cross Device Development] TMax2001:
Hi everyone I'm new, I have installed the kernel 04/17 on my S8 for a few days and it is great.

For now I am with the standard settings and I must say that it is very fast compared to the original, I am not a gamer, but I use my device a lot for Youtube, Photo montages, Adobe and Google Docs, I was going to run an oc of the cpu , I have tested the frequencies and they are all stable for me except Big 2.8.

In your opinion, what frequency do you recommend to set Big / Little without draining all the battery in a flash and having excellent speed?

Thanks to the developer.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
If you want more battery save you can use

Cpu BIG 1,8ghz

Cpu LITTLE 1,8ghz

Dvfs 65°C

If you want powerfull for rendering in any place

Default is best for that or just add more DVFS
[Samsung Galaxy S8 & S8+ Cross Device Development] Devil90:
Yes, but on Little CPU you can also set 1.9Ghz or even better 2.0Ghz (in case they are stable) since the consumption is low and the frequency steps 1.8-1.9-2.0 have the same voltage.

As far the Big CPU is concerned, the best frequency of OC remains for me 2.5Ghz according to my tests, higher frequencies if not for the benchmarks you will not notice any difference if not a greater consumption of battery.
[Samsung Galaxy S8 & S8+ Cross Device Development] Illutorium:

[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@ up

I had tried in the past 2 - 3 times to unlock GPU/CPU/RAM freq/voltage, but sadly failed.

Anyway i've an last new idea that could work, but actually the priority is to make this kernel 100 % stable and then to build AOSP with my optimizations.

After that i'll try again with OC.
[Samsung Galaxy S8 & S8+ Cross Device Development] Devil90:
A2N AOSP + A2N Kernel = kaboom!
[Samsung Galaxy S8 & S8+ Cross Device Development] Triger972:
35k-40k antutu score incoming oof

I have a question when I listen to music or play small games like sudoku in the same time what configuration can I do to have more time and save the battery in this kernel ?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Powersave profile.
[Samsung Galaxy S8 & S8+ Cross Device Development] Triger972:
Ok so only this profile not useful to put the energy saving mode + the powersave profile on my s8 ?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Power profiles from the (stock) ROM doesn't control CPU/GPU Freq at all.

It's only for screen brightness and resolution.

Even if you can set "reduce CPU speed to 70 %" once you check with any CPU Freq app you'll notice that the CPU Freq is still running at max Freq 2314 MHz.

Tested even with stock kernel on stock ROM, it doesn't work at all, samsung or google failed here.

So, i do suggest to keep there "optimized", keep "adaptive powersave" disabled and go with A2N profiles, the only thing that really works lol.
[Samsung Galaxy S8 & S8+ Cross Device Development] Triger972:
I didn't know about the performance options etc I thought something was wrong with that.

Anyway your kernel really brings something new to the s8 and I feel like I'm rediscovering the performance of my smartphone and that's when I realize that samsung slow performance any smartphone lol it's strange now i can play games with 60 fps without lag and no close games random crash but sometimes i have a crash bt but is a little problem not a big problem anyway i love your kernel so much i hope the kernel will be really stable in the future although i think the s8 will still have some surprises in performance antutu score
[Samsung Galaxy S8 & S8+ Cross Device Development] Askael:
Hello. thank you for your hard work. one request - can you somehow correct the control of the flashlight? due to the fact that your core has control implemented, the brightness is not regulated by standard means. I'm not going to buy the app, because I just want to install the kernel and forget it. but it is inconvenient without adjusting the brightness of the flashlight
[Samsung Galaxy S8 & S8+ Cross Device Development] predict9:
dev this kernel so amazing bein usin the latest version encountered 0 problems

using 2002mhz on lil core and big 1807mhz its stable

my question is i got bored of android 9 i want to uprgade to android 10 oneui 2.5 but i want to ur kernel on it

so u still workin on it ? if possible i would like to test it keep up the great work
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
For android 10 this kernel must stable first very² stable like stock kernel no faced problem or less bug if that realized next for note 8 and go to a2n AOSP after that maybe for android 10 may be you will be wait a long² time🤣🤣🤣

This report is for kernel build from 06.02.2021.

I don't provide support for such old releases, therefore i suggest to update to the latest build.

Something went wrong with the log .. there is no useful debug data.

Generate the log right after the random reboot happens .. do not reboot yourself before or even worse do not shutdown the phone.

Update: maybe it was a "soft-reboot" ?? if so you need to grab logcat then reboot and grab last_kmsg.

But actually you guys should only report bugs for pre-18 build i had uploaded last sunday.

Was it from pre-18-build ?

OC was 2652 MHz.

Anyway there is also no useful debug data.

The provided logs looks normal, hence the reboot reason was not "random" but normal by "user-request".

At least according to the logs.

Summary:

actually i don't have no one bug report for the pre-18-build i had uploaded last sunday.

Anyway i do is still believe that it's not fully stable, at least with zRam enabled.

Still searching for bugs.

pre-18-build or 17.04 release ???

Hello, thanks for you report ! - This is actually a good finding ! - So far you are the first who reported this. When i had added "Flashlight Brightness Control" i even didn't know that it's possible to adjust it over stock kernel or stock ROM.

Therefore the default value of 5 in my app/kernel corresponds to the stock value of the stock kernel of "3" (same brightness). Anyway my value of max. "15" is still higher than the stock value "5" in terms of torch brightness. Also i don't know if i can manage to make it possible to control it over stock method + my custom method together. If i can't fix it due to possible interferences then i've to say sorry, but i'll check this and inform you.
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
Dev try for GPU oc further.. I know it's not easy at any rate.. but I bet that you will definitely do it if you want to

I believe it is pre-18 build.

Kernel version says " 4.4.111-a2n-gb4be8194 #4 Sun Apr 18 23:36:18 CEST 2021 "

I think it was a soft-reboot instead because I didn't hear any vibration from my phone when it was doing random rebooting. But I'm not sure.

Spoiler content hidden.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@ up

why you use "vanced" ? It's outdated app and was replaced with the much better app "pure tuber".

It think that's the reason why it gets uninstalled automatically, nothing to do with kernel issues.

Btw: for now it's not needed to post logs related to random reboots. I'm working on it.
[Samsung Galaxy S8 & S8+ Cross Device Development] bntnja:
Actually, it just update just a day ago. quite new (except for the magisk version, it's so old)

and I'm using the root version, so it acts like a real youtube app.

but the problem above seems to be from the app, I may have to report to the dev.

Anyway, I have found the sweet spot between the performance and the heat. and it's working quite well!

Thanks again :)
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
But "pure tuber" is lots better. ;)
[Samsung Galaxy S8 & S8+ Cross Device Development] goodness4411:
Hi... i'm new again here... long time since era Xperia 2011 line... hehe

i used to flash custom kernel but without root.. because i just simply want to get benefit of custom kernel without loosing mobile banking ability...

yes, i have tried with magiskhide, etc. but it encountered problem somehow

is it possible flash this kernel without root?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
With MagiskHide enabled it should be possible to use banking apps.

Also you should test with "SafetyNetChecker" app if it's green (passed).

If it's green and your banking app still doesn't work, then you should report the issue in the Magisk thread.
[Samsung Galaxy S8 & S8+ Cross Device Development] goodness4411:
i've tried, untill safetynetchecker is green..

i'm also try with riru and LSPosed

one m-banking works, another not.. it looks like m-banking apps nowadays more advance in detecting root...

i'll do ur advice...
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Good news: i was able to fix it. So it'll be fixed on next official a2n kernel release.

btw: it's OK if you don't mind about the full version, kernel works fine out of the box.

But keep in mind that you'll still have to update from time to time the kernel, since (for now !) there is no feature implemented that informs you when there is a new build ready to flash.

For now the best thing you can do is to "Watch" the thread, then you'll be informed about new releases.
[Samsung Galaxy S8 & S8+ Cross Device Development] Askael:
You are so amazing, dude! Thx for you hard work, impressive job.

There will also be a small request. can you make it possible to switch selinux to enforcing and permissive mode from the terminal or by using an app like Mtweaks. This can be useful incase your banking app requires an enforced phone (e.g. rebooting)
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yes you can if no root just some few feature cannot functional properly
[Samsung Galaxy S8 & S8+ Cross Device Development] predict9:
the pre 18 version its very stable
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Real enforcing mode isn't possible on custom ROM/kernel, but i've added an fake enforcing mode.

What it is ?

In current release even with MagiskHide enabled if you check in a shell terminal the selinux status with:

getenforce

you get

Permissive

but in next build we will get:

Enforcing

:cool:

But anyway, i had never problems with my banking app using permissive.

SafetyNet is OK (passed)

Maybe there are some smart apps that checks enforcing mode like mentioned above, if so then it should be fixed completely for all sensitive apps.
[Samsung Galaxy S8 & S8+ Cross Device Development] traversone:
dear DEV, I hope this "fake" enforcing status could be set by dedicated option in the APP. If it is true that some smart app could check enforcing mode, it is also true that some other apps work better in permissive mode.

thank you for feedback
[Samsung Galaxy S8 & S8+ Cross Device Development] Zkiller112:
I install it since 2 weeks, i can use "no-root" app like revolut with magisk hide by installing apk on apk mirror, but since last version a2n_kernel_g950x_9.x_2021.04.17 i install it without magisk and i can combine speed and "no-root" app.

It's a normal use? Magisk is necessary?

[Samsung Galaxy S8 & S8+ Cross Device Development] bntnja:
Random reboot here (not a soft reboot since it's showing Samsung Galaxy S8 splash screen)

here: last_kmsg
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@pranil60

Using build 17.04 ?

In release 04.17 you need to flash magisk in twrp after you flashed the kernel and then you also need to enable MagiskHide in MagiskManager app otherwise SafetyNet will NOT pass.

But in next release Magisk/MagiskHide is not needed anymore to be able to pass SafetyNet.

But you still need to flash Magisk after the kernel in order to get root access. Root is required for some features in A2N app, but not all.

Edit:

As it turned out itsn't a good idea to set fake_enforce on boot. Probably it shouldn't hurt when it's set after booting is completed. So you will find a switch in next a2n release. (demo app)

zRam value isn't an issue here. Next build will have set 50 % zRam by default.

@ ALL

Thanks for all the reports and logs ! - Actually you don't need to post further reports/logs.

I'm not sure but i believe that now it's 100 % stable. I'll test further 3 days before releasing it to make sure it's really stable. So far after 24 h, no random (soft) reboot and no FC (force close apps) happened.

btw: actually i'm implementing a new feature that checks if there is a new a2n release when you open the full/demo app. But for this service i need an FTP server, or any other sort of web hosting where i can have a link to a text file like this here., which contains just the release date.

I've already tried this on my offered FTP server, but it doesn't allow such direct raw access to the files.

Also honestly i don't want to make our FTP server slow. - Again, it's not my own FTP server, also i don't pay anything for that server. I got the FTP server access from my old friend from galaxy ace 2 forum.

So if someone is aware of some free web hosting service, let me know. Of course it should be legal solution, not an hacked web server lol.

Also it's for me very important that the service is for free, since this project is almost for free.

Edit:

already found one :D
