[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
OK guys, i've uploaded pre3 build !!

It can be safely used with the A2N app V. 4.0.

The only thing you need to do is to make sure RAM --> "swappiness" is set to "175". (This will be the new default in next version of the app.)

For non A2N Full users: swappiness default of "175" is already set in pre3 and future builds.

Note: in case of random reboot (even for the first time), please post last_kmsg, helps to make this awesome kernel more stable. In case of random soft-reboot you could post logcat, but i've to remember that soft-reboots are caused by the ROM and therefore those soft-reboots can't be fixed by kernel updates. But you can post anyway if you want me to look into it, just to have confirmation if it's ROM bug or not and following my suggestions.
[Samsung Galaxy S8 & S8+ Cross Device Development] Driieel:
😂

I'll test it, but I would die in version 16.01 quietly 😂
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Hmm that explains why there are random reboots or soft reboots after a kernel updates lol besides that i dont have reboots anymore randomly, anyway gonna flash it soon 😄
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer i got a soft reboot with kernel pre3, but i dont know if it is becus a kernel update ot something in the rom or kernel what caused it.
[Samsung Galaxy S8 & S8+ Cross Device Development] george343456:
Ohhhh yeahh💪😎
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Im impressed now😄
[Samsung Galaxy S8 & S8+ Cross Device Development] george343456:
Thanks i tried my hardest to reach 340K😂
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Uploaded build pre4. :cowboy:

It should work more stable !
[Samsung Galaxy S8 & S8+ Cross Device Development] george343456:
Stable as in it wont have random reboots?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Nobody knows ... compiled a few minutes ago.

pre3 build had zram decompression error and therefore caused a soft-reboot. It happened even with my S8.

I did some changes where i think that could cause this bug.

Now we need again patience with hard testing.

Like always, we can say it's stable if it'll pass 7 days uptime in a row.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
seems like its running better then the pre3 build and slow loading apps issue is fixed, only thing i noticed theres again issue that the mem managment is reloading apps sometimes.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
For Max multitasking use zRam 100 % and swappiness 175.

Everything else will be fixed/improved on next build.
[Samsung Galaxy S8 & S8+ Cross Device Development] user900:
I tried to install just the kernel zip now I am stuck at bootlogo. if i tried to get into twrp it won't load. tried installing twrp again with odin still stuck at loading twrp. can anyone please help me with a solution? thank you.

edit: managed to fix it by installing the newer version of twr 3.6.9.1 and and flashed a different kernel
[Samsung Galaxy S8 & S8+ Cross Device Development] george343456:
Are you using a custom rom? And if yes what rom are you using?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hello, you may missed this step ? :
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Alright, anyway changed already the settings what you recommended😄 btw tried also to backup to a external flashdrive or usb m.2 drive, but transfer stopped everytime on the same point on the flashdrive so i guess its something wrong with and the m.2 drive didnt want to mount guess the rom/kernel or twrp doesnt have drivers for the m.2 drive🤷‍♂️ anyway gonna buy a new flashdrive or larger sd😊
[Samsung Galaxy S8 & S8+ Cross Device Development] psygenius:
Random reboot on pre4. Debug attached.
[Samsung Galaxy S8 & S8+ Cross Device Development] user900:
didn't work for LOS19 stuck at bootlogo even with patch installed after kernel
[Samsung Galaxy S8 & S8+ Cross Device Development] __Alchemist__:
Can i use this kernel with Lineageos 19?

Should this kernel even work with LOS19? Would love to use it again after almost two years. Best kernel ever.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
This kernel is currently only for Android 9.

So no wonder, anyway thank you.

Maybe soon, just keep an eye on this thread, really worth it.
[Samsung Galaxy S8 & S8+ Cross Device Development] __Alchemist__:
Do you remember this @ace2nutzer xD Trust me i know the worth of your kernel. And im amazed that you still develop it :D Thank you a billion times.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
:ROFLMAO: sure i remember this creazy post ! - I was impressed to see this.

Btw: 250k score in Antutu ? :LOL: Actually we get 340k, see here and probably this is even not all, in next build we reach likely even higher scores.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Best tester ever i see may you can try may method too modify the cooling inside phone check my channel at zidan rafif pratama

Profile pic is cat
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Got random reboot after using whatsapp and turn off the phone screen

For perfomance very well good no over heay issue and other and for battery more way better then before update HMP may still at memory management is get the issue? I hope you can fix it as soon as possible and i wish i can touch the menu of voltage custom GPU and CPU that will be great and this samsung 8955 chip will be beast
[Samsung Galaxy S8 & S8+ Cross Device Development] __Alchemist__:
340K? Damn you guys made a lot of progress. I need to beat that! I promise if you bring it to LOS19 I will run my phone on a sub zero peltier cooler with thermal paste in between 😂😂
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Woah that will be crazy bro hahahah i use peltier tho but not into SUB ZERO hahahha i want try it direct cooling attach to the cpu and boom no throttle but i only have one phone here 🤣🤣🤣🤣
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Got a random reboot while i was sleeping
[Samsung Galaxy S8 & S8+ Cross Device Development] recoman:
Deep sleep not working on kernel 16.01 and pre1,pre2,pre3,pre4
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Soft reboot happend on kernel pre4
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Thanks .. probably i've it fixed ... i've updated lz4, lzo and gzip lib to the latest version from latest stable Linux kernel (upstream) since we had several times decompression errors. Did that 2 days ago. Phone works perfectly now. Later i'll release new official build.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
1. The app you are using is not supported with this kernel, see post #3.

2. Deep sleep works properly, see my screenshot, made it today.

3. Use proper app for deep sleep issues. I suggest betterbatterystats (use latest version beta) (4 free 4 xda users)

Wifi doesn't working
[Samsung Galaxy S8 & S8+ Cross Device Development] Driieel:
I went 4 days without rebooting on v16.01. I rebooted myself as I had to use twrp. I noticed that the S8 gets slow over time, touch response time, opening apps, etc. I don't know if it's a bug.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@ up

it's just luck lol, stability + speed will be much better in next build !

Delete saved wifi connections and re-add them.

This happens sometimes when switching between custom kernels.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer playstore 28.9.13-21 pr 423174656 is the latest right? Becus a2n app give a error theres a new version available of playstore, i tried to update it and its says its the latest, kinda confused now
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
28.9.12 is latest supported for now.

Later 28.9.13 will be supported too.

It's more or less a wrong message from the a2n app.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Alright, good i let you know about it becus it isnt something on my end😅
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Is there a way to disable the auto updating of Google playstore, everytime i restore a nandroid with a older version of playstore or downgrade to a older supported version it updates automaticly and then i cant use the a2n app
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
You don't need to restore a full /system or /data backup for just rolling back one app. Instead, if you don't want to wait till it's fixed automatically, simply download previous version of Google Play from here:

Download Google Play Store APKs for Android - APKMirror

Download Google Play Store APKs for Android - APKMirror Free and safe Android APK downloads

www.apkmirror.com

(scroll down to "All versions" and choose the appropriate package, every version should work, but use for "Android 5.0+" and if available choose "arm64-v8a" architecture. Also check if your language is listest, if not, choose a "universal" package as it should support you device language.)

and install it over the newer version. That way you don't loose your settings from Play Store APK.

The site is safe, since hash sums matches with original APK from Google.

Anyway, 28.9.13 should work now.

As for disabling Google Play auto-update: well that's a very good idea and so far i didn't investigate how to do that. The only idea that i've actually is to disable the corresponding "receiver". At least this trick worked a few years ago, but i've no idea if that would still work on modern APKs, since they are now almost all very hard encrypted.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
alright, thanks for the help it works lol, if you find something to stop auto updating playstore let us know😊
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
need a little help here,

does anyone knows any trick to install secure folder? cause that smalipatcher trick seems not to be worked here...

I need secure folder more now cause alot of personal and commercial stuffs are getting mixed up here and to sgregate them is alot of pain. just want to create secondary device in case and also it's easy to copy stuff using root browser of secure folder.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Any eta when the next build will be available?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Maybe this weekend.

Unfortunately i had after few days an soft reset.

Reason was due to issues with ashmem driver (used for ART dalvik cache). And even I'd removed an weird patch merged by Samsung, it still causes issues. And since it's painful, i've updated it right now also to AK 4.9, now i'm testing it.

Anyway, somehow i've found out how to trigger that soft reset issue, more or less at least ... like that: playing YT videos, then turning screen off and plug to charger, then it'll soft reset (you see the Samsung boot animation or that happens after you turn the screen on after a few seconds.

Lost connection and strange reboots after installing kernel from 16.01
[Samsung Galaxy S8 & S8+ Cross Device Development] mustafa2147:
android 12 aosp supported or only android 9?

edit: never mind I read the thread and it does'nt support android 12, would love for the next build to support LOS19 ✌
[Samsung Galaxy S8 & S8+ Cross Device Development] Epil0g:
Any news on next build release? I'm getting tired of those system freezes from 16.01 build (currently using pre4)
[Samsung Galaxy S8 & S8+ Cross Device Development] Kostik680:
Dear developer, please release the update as soon as possible
[Samsung Galaxy S8 & S8+ Cross Device Development] Kostik680:
Make a new tutorial on setting up a YouTube
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
New Release is Up: Kernel V. 2022.02.02

Improved stability

HMP: improved for battery and speed

CPU/GPU: updated DVFS driver

Lib: sync LZ4 LZO ZLIB with LK 5.16.2

Ashmem: sync with AK 4.9.194

Samsung Dex: WQHD support with every adapter - thanks @ craftingmod

A2N Kernel Control V. 4.1

Improved stability

Updated defaults (swappiness=175)

CPU/GPU: DVFS Max 95 @ 100 °C

Release Notes:

I'm still not sure if it's now fully stable, but since many of you are inpatient, here you go.

But for sure: i was able to improve battery life and speed.

Speed is slightly increased since we can set now finally 100 °C stable !

In my case i can pass several times Geekbench @ 2,7 GHz @ DVFS 100 °C.

I can pass it even @ 2,8 GHz, but with DVFS Max 80 °C lol, gives higher score in single bench, but lower in multi-threaded bench.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Hmm ppl should be more patient, anyway your the best lol, try the new build soon😄
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer something is wrong with the servers?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
hi guys everyone here dev and epic tester,

for 5 mins test i never touch under 2 ghz

And that test i have been change the thermalpad with aluminum metal plate and use thermalright TF 8 with 13.4w/m.k and that the result the lowest juga 90gips as you can at 4 big core when 2,65 Ghz touching 100°c it dropped like fall from plane but that fall to 2,3 ghz maybe i didn't see real time because the app have delay 500ms maybe and this is my challange

Anyone can beat it ? Hehe

.

.

Ah yes i forget it

Settings i use

CPU Dvfs 100°c

BIG core 2,65 Ghz

LITTLE core 1,89 Ghz

GPU 572 Mhz dvfs 100°c

Up Threshold

CPU

BIG core 95%

LITTLE core 45%

GPU 50%
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I see why this build should give higher scores. It unlocks a little bit more of CPU performance with proper cooling through that 100°C DVFS. The performance oriented HMP should help too. I'll update y'all.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
It should work now. Like always due to Play Store update, lol.

I'd still no time to check if i could solve this issue in a better way.

So from time to time this warning appears and will disappear automatically after a few hours. You guys even don't need to report this.

Yeah, CPU gov switches Freq every 40 ms and DVFS driver even every 12 ms if needed. Also the DVFS check thread runs only on little CPU to avoid performance loss on BIG CPU.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Alright, seems it fixed itself
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Hmmm every 40ms that why when play game have lot of stuttering right? I have compare with my friend phone midrange phone but have stable framerate at 45 or 30 but no stuttering hmmm lets test it with fixed freq at 2,3ghz or may you dev can improve the delay more shorten like 14 or 10ms ?

And for testing the new kernel with 100°c peak i will make the video about it

.

.

And for everyone how i mod the alumunium plate to the soc watch the video you can make your own tho but remember about sensor temp at left soc between sensor and soc when you use aluminum plate you must make the flat as possible to make the sensor accurate

On the video i have small plate but now i have big one and it fitted all surface of SOC more stable freq range 2,15ghz to 2,65Ghz if you can more 2,65Ghz you can try it feel the heat to you hand🤣🤣🤣🤣 at power button position
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Maybe. But did you test also with latest build ?

Make sure you use proper settings for games like this:

CPU/GPU:

max stable freq

DVFS 100 °C

up_threshold 45

RAM:

zram 100 %

swappiness 175

echo 2314000 > /sys/devices/system/cpu/cpu4/cpufreq/user_scaling_max_freq
echo 2314000 > /sys/devices/system/cpu/cpu4/cpufreq/user_scaling_min_freq

But you need proper cooling to hold 2,3 GHz stable.

Test first how it goes with static 2,3 GHz. If it doesn't make any difference, then it's not related to the cpufreq driver.

As an old PC tuner i suggest to use copper plate with "Artic Silver V" thermal paste. Or even more efficient: connect to the copper plate an heat pipe an transfer the heat out of the phone and cool it however you like ... but then you can't really use it as a "phone" lol.

But as an powerful Dex PC at home, for sure a good idea. ;)

btw: someone already tested Dex in Full-HD ? - Is it working ?
[Samsung Galaxy S8 & S8+ Cross Device Development] xperia modder:
@ace2nutzer what happened to f2fs support , just found out when my phone was bootlooping , is there a build with f2fs on ?

and is there any one ui rom that even supports it ?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
100C DVFS very slightly improved performance, as expected. 444 single and 1830 multi on 2652MHz. I assume we are at the limits of what this chip can achieve on S8 chassis, and we are in low Snapdragon 845 territory for CPU. Indeed a win. Can’t run antutu right now. I will try tomorrow. Probably an S8+ at 2704MHz with excellent cooling or a golden sample S8+ (2808MHz stable) would score higher. Maybe at that point 1900 multi would be possible. But hardly.

100C DVFS Made 2314MHz fully stable. 396 single and 1736 multi. It’s basically the limit of what can be achieved on stock frequency. It’s a little below Kirin 970, unsurprisingly. All it takes though is a 2496MHz overclock to be on par. 2574MHz is probably the sweet spot. My S8 struggles above it. 2652MHz is a hit or miss with stability and 2704MHz crashes more often than not.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
F2FS support was removed long time ago, sorry.

@xperia modder was it ever working ?

F2FS support was never fully implemented in kernel.

So i wonder if it ever worked.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Thx dev giving me much tips

For dex i try on full hd but not dex just mirroring with my usb type c to hdmi the merk is vention with 3× usb 3.0 maybe i this day i will try dexfor this kernel

And i use latest kernel

.

.

Edit when i see thermal paste arctic silver V that thermal paste have conductive chance because it use pure silver that scare me cause i have burn some resistor cause water ehe cause by too cool maybe i try copper plate

.

.

Okey have been test again without any cooler just phone with start battery temp 33°c and for 3minute play honkai impact 3 at open world chapter i see the freq change but no stuttering it stutter when load some object like enemy or building maybe storage or ram have heavy load 4gb ram maybe not enough for open world hokai impact buat ussual fight on small scale render like one room that still have 50 - 60 fps

And next game i will try PUBG mobile

Forget to mention the pict that my prove about modding the cpu heatsink more stable up to 2ghz before that i usually 1,9 Ghz

.

.

Ah yes dev i fell improvement when open any apps is fast to load like marketplace app instgram facebook whatsapp ,etc nice and good dev

I hope for next build you can make

Voltage Control both CPU and GPU

That will be incredible feature on this kernel👍👍

Random reboot happend on build 2.2.22
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I have the feeling that memory performance decreased by around 10%. Needs more testing.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Nevermind. No decrease. I’ve seen a slight improvement in CPU performance on AnTuTu V7 at 2652MHz thanks to the 100 DVFS. Yes, I’m using V7. V9 with 3D Bench lite tends to loop.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Voltage control would be a dream and I would already be running 683MHz on GPU and kicking Snapdragon 835’s arse. I think it’s not easy to do that on these modern devices though.
[Samsung Galaxy S8 & S8+ Cross Device Development] psygenius:
Hi Dev.

Hope this is helpful. Had a random reboot on latest release while phone screen was off.

Debug attached.

Thanks
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Ace, as I was scrolling through ancient G95xF threads on XDA I noticed something very odd.

Two ancient pieces of development, Xceed Kernel and Batman ROM, when paired together, seem like they achieve EXTREMELY high GPU scores. The results are old so they are recorded on AnTuTu V7.

For comparison, the Mali G71 MP20 @572MHz on your Kernel, on the same benchmark scores between 93,000 and 97,000. This one scored 143,000+?!!!! That's ABOVE Exynos 9810 and on par with Exynos 9820. Is this fake? There is little to no source left in those threads but again, if there is truth to this, maybe you could embed it in your Kernel to achieve new levels of performance.

Memory score is red and very high for V7 because the user was using F2FS.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
For comparison, these are the best scores I respectively got on G950F and N960F on AnTuTu V7. So same bench platform. The score of that S8 from before is literally above the overclocked Mali G72 MP18 in my Note9. How. You could dig deeper into this technically, and it's a huge performance improvement we are talking about, so maybe this can catch your interest. Just hope it ain't fake scores. It seems they are achieved when Xceed Kernel and Batman ROM are paired together. There are a bunch of scores with that crazy GPU result.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No idea, but that's a bad comparison.

Download those old kernels or roms and then let run latest benchmarks.

Also S8+ is a bit bigger, so may it has bigger thermal plate, resulting in better performance.

Also i didn't say that's all for speed, probably it's still possible to improve it a little more. I'm actually working on Note 8 support. Already merged latest Note 8 kernel soure code on top of latest S8 kernel source, since Note 8 soure is more recent. Already checked the code, it has some updates to GPU driver and memory management.

A

Ace that is not a bad comparison. My S8's chassis is actively cooled. So it's at least on par.

Also, 94,000 vs 143,000. That's not little. That's a LOT
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
You never ever can cool the chip with external fan outside the phone.

That cooling method will just cool down the (external!) chassis of the phone. Sure with time it'll also cool down the chip, but it's useless as it takes too much time. The chip increases its Temp in the milliseconds range.
