Yes you can pretty safe use 839 MHz.

I've found this interesting article., about how much voltage a CPU can take.

They say up to 1,4 V it's safe with proper cooling or like here with proper DVFS driver. I couldn't find much info about GPU, but it should be the same, since they are in the same nm.

As you can see for CPU we can set max 1,4 V. And for GPU only 1,0 V.

It's even possible to push the GPU @ 1,4 V but it's not worth it, because 839 MHz @ 1,0 V is already very hot in full load. Also I've capped to 1,0 V for GPU, because I think that nobody needs more than 1,0 V to make 839 MHz stable. And honestly if 839 MHz won't work stable even @ 1,0 V, then it's really better to use 764 MHz instead to run the phone to the hell for just having a bit of more speed as compared to 764 MHz.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Waiting for R55 Hehe

Gpu improvement at gaming

Moroaudio maybe :v from Noxxxious source code

Cpu stability

Memory management

Higher usage bus for GPU

Maybe that for the update :>
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes, new changelog Is similar to this.

And you guys already know it, if I miss my own timeline for releasing new build then it means like always I'd decided in last minute to fix more things and to add more useful features. 👍
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Ace isn't going to stop squeezing this Exynos 8895 until he can send people to Mars with it :ROFLMAO::ROFLMAO:
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Exynos 9810 is making numbers 😱this is pretty powerful. I think I should try hard to get 1900 on my S8. But 2000 is impossible with my bins. It’s funny because what our E8895 can achieve at 2808MHz with many sacrifices, E9810 can reach at just 1690MHz no problem.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
@ace2nutzer

wait what? does that mean that for all this time memory management readahead IO were capped at 128k randomly?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes seems so. And do you know what previous patch about __GFP_NOWARN will fix?
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
i'll try to guess.. blkcg is related to memcg which maps memory for subsystems IO, if it's buggy or leaking then it could lead to page allocation failures resulting many things as filling up memory with junks and causing OOMs? no?

edit: forgot to say that considering the other patch is in the cfq io scheduler, then it's a fix for IO scheduler (edit 2) queue-ing??
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
So

I tried to challenge a Snapdragon 888 S21 FE with my S8 at 2314MHz in app launch speed.

It didn't go well :cry:☠️
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
i bet that s21 has less installed apps than your s8 :D
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Nope. It has more. Way more. But we both optimized the phones for the run right before the test.

It just shows, the immense single core performance advantage that the X1 Core grants the 888. It wasn't even a challenge. At 2314MHz the 8895 just couldn't hold a candle. I didn't want to run 2704MHz since it would be Quad, and quickly drags the phone to 100°C. This is the stuff that would require a single core boost. But I strongly believe that even at 2808, it would have lost.

I tried with my Exynos 9810 at 2314MHz too, and, surprisingly, it actually kept up.

Meanwhile my 835 took the worst beating out of all. The 8895 did way better.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
welp, can't beat nano tech advancements.. 10nm vs 5nm lol

not to mention the ram bus speed differences
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No, it's a fix for the memory allocation failure warnings you saw in last_kmsg or dmesg. And hopefully this will fix also rare bootscreen glitches.

Toch boost duration enabled at least to 1000ms? And btw in recent releases the touch boost freq for both big lit CPU was reduced to be more efficient for battery. If you set over scripts to allow boosting at max freq then apps should open faster. (Especially if you use OC) but for me it's fast enough.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Mate Ace I'm not complaining about speed. It's buttery fast. Boost duration was all maxed out as far as I remember. Recent release may optimize it a bit more, but I was trying to strike WAAAY above our weight class there :LOL::LOL::LOL::cry:

I wasn't trying to challenge an S9, or an S10, or even an S20. It was an S21 bro LMAO. It isn't even something merely about processor speed.

It's UFS 2.1 vs 3.0

It's 1794MHz vs 3200MHz MIF

It's one high performance Core made to run at high frequencies vs 4 Cores running at a lower frequency

You did so good that our E8895 can outperform in speed some E9820 devices and most E9810 in these daily tasks (It surpasses my E9810 Note 9 in terms of performance consistency, too), but bro, 4 generations ahead, that's just straight up mission impossible.

I just did the test to have fun, lmao. But I was really curious, to be honest.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
close enough 😎

well anyway if you really fixed it then it means we'll have better and memory efficient kernel.. not saying that it isn't currently, but more fine tuned

i hope you're enjoying the developments :D

ps: my screen cracked, it still works fine tho, fixing it almost costs half the price of a secondhand s8, this suckssss
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Our S8 may be old, but it's still a piece of art, and so is the screen, that's why it's so expensive :cowboy:
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@ twiq

Yes you was close. :)

@TechNoobForSale

I know you are not saying it's too slow.

But you was trying to make a race without to give full-gas hehe, that's why I told you about CPU not running at max freq. 1456/1703MHz lit/big for touch boost. ;)
[Samsung Galaxy S8 & S8+ Cross Device Development] Pistero07:
hello good afternoon, I am experiencing a problem connecting a samsung syncmaster sa300 monitor. (via samsung dex with hub) the monitor flashes, shows an image and turns off, continuously as shown in the video. I connected this same monitor to a netbook and it works perfect.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Probably wrong resolution or missing driver for the hub.

What is the model name of this USB hub? (maybe missing driver)

Did you test if it works with the stock kernel?

Also did you try to change resolution in Android settings?

And one more: in A2N app --> screen --> try to change resolution for Dex.
[Samsung Galaxy S8 & S8+ Cross Device Development] Pistero07:
1- The hub has no name, it is a Chinese one. I clarify that when connecting it to the tv, (samsung tv 50) I do not have this problem. I attached a photo of it

2- I am going to try at this moment with the stock kernel

3- try changing in many resolutions and the same error is reproduced
[Samsung Galaxy S8 & S8+ Cross Device Development] Pistero07:
With the stock kernel I also have the same problem, it gives a few more seconds of image, but it flashes again
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Alright. :good:

OK alright, for sure missing driver for that hub.

Try to provide more info about the used chipset from that no-name hub.

With proper driver it should work.

Here you may need to test both, change resolution while USB-C is connected with the phone or try to change resolution in a2n while it's disconnected, then connect. Because I don't know how the sequence works exactly, since I don't have USB-hub and no Dex stuff. But maybe @rtyuakatsuki can help you fix this issue.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
If that give second of image i was curious about the vga cable as i see in you picture you wajt to connect hdmi to VGA i think that the reason the image just while show and some of adapter using cheap chip for emulating the DP to hdmi
[Samsung Galaxy S8 & S8+ Cross Device Development] Pistero07:
I'm going to look for information about this hub, I need to find its chipset.

I have tried to change the resolution in the two ways you indicate, I get the same result

I clarify, I just connected this simple adapter and it works correctly
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I think this adapter using lontium chip that kinda cheap chip for emulating the dp to hdmi and the high end is LT8711HE that the high end but that chip deliver aomerhing weird flash somwtime
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
For this one is kinda unique that adapter maybe connect direct from type c to hdmi and that why work well i think
[Samsung Galaxy S8 & S8+ Cross Device Development] Pistero07:
It seems strange to me, when I connect it to the TV I don't have any flashes. This last adapter (white) worked fine with the monitor, but it doesn't work for me since I can't charge the cell phone
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
And what if you connect this "galga network" hub to your laptop and then connect the monitor, than works?

Fun fact: on their homepage they state that it's plug-and-play for Linux and compatible with S8 lol.

Still didn't find the chipset type. In the worst case you need to open it carefully and post a photo of the chip inside lol.

Or other idea: try to connect to a windows laptop and try to read the chipname from the used driver in driver manager.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Okey i think the phone broke
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
R55 is up !!

Changelog is on post #3.

Enjoy guys !!
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
YESSSSSS HAHAHHA YIIIIIIHAAAAA time tk test the new feature

edit

i feel lost something how about Mali GPU power policy ? only that i not found in the app hehe

hmmm after i see relaxed powersaving for gpu hmmm maybe that the reason you not add the always on button
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
You don't need to mess with power policy for GPU. Like I said it's done automatically. When you play any game, GPU will stay online all the time now. (I've fixed the issue directly in mali driver in kernel)

Once you quit the game, the GPU will go offline after 1000ms if no job.
[Samsung Galaxy S8 & S8+ Cross Device Development] kidd25:
Hi!

We could slowly turn to how I can get the price of the application back. The phone (SGS8 DSL1 OEM ROM) is lagging despite all the settings. As in memory when reloading, as when opening an application. I can't use this kernel this way.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hi, i've refunded your money.

But honestly i didn't understand your logic, as i told you, the lagg for multitasking will be fixed in next update and u can use in the maintime another kernel. Well later u'll face it's ok now and likely u'll buy the app once again. :highfive:
[Samsung Galaxy S8 & S8+ Cross Device Development] kidd25:
Will I see a refund on my bank statement? If the updated kernel comes out in the near future and is available for use, I will reinstall it. How did you get your app refunded when you don't know what gmail account I bought it from?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
So was it successful ? did u received e.mails about the refund ??

I think i'll be refunded ont the same way how u payed the app.

I don't need your e.mail address, i only need the GPA.xxxx.xxxx.xxx order number .. which u already gave me some days ago, u posted here in forum or u was sending me this over PM .. can't remember... Anyway u're actually the only one who ever asked for a refund, so i had bookmarked your Order, so i was able now to refund your order .. it was just 2 clicks for me. ;)
[Samsung Galaxy S8 & S8+ Cross Device Development] kidd25:
I thought it was more complicated. :)
[Samsung Galaxy S8 & S8+ Cross Device Development] monoik:
So, we're still waiting for google to re-enable the app, right? Or you're still developing the kernel?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Google accepted my appeal :o :good::good::good:

App is still offline in Store because i want to upload directly the new Version instead the old Version first !

Kernel is ready and fine ... only working on App actually.

Basically i'm adding a new feature (surprise) which u'll love it ...

and trying to fix the back-arrow button ... but that is literally broken since years .. because i had to remove some code or lib in the app to fix compiling errors ... this app is not autogenerated with Android Studio ... it's made by hand like working on kernel ... opening source files with simple text editor and start coding. :)
[Samsung Galaxy S8 & S8+ Cross Device Development] monoik:
Thanks for the update. Hoping the release is really near. The current version has freezes so severe I couldn't pick up a phone call, and when I called back and the person didn't answer, I couldn't hang up ?

Don't really want to switch to a different kernel, since I have encrypted storage because of work and don't wanna risk a wipe.
[Samsung Galaxy S8 & S8+ Cross Device Development] kidd25:
I have the same. I didn't want to get the money back so soon, I was waiting for the new release. but in principle I got the money back, the app disappeared from the phone, I can't see the app in the store (I think the developer hasn't put it back in), I don't see it on the account statement (I think I need 4-5 days lead time) the end result of the test, because unfortunately I can't replace the rom / kernel at the moment ... if everything is okay with it and I don't lagg, then I will buy it again ...
[Samsung Galaxy S8 & S8+ Cross Device Development] khanhbang2013:
You guys should not be too concerned about this, as devs are growing, we need to wait, I am sure dev is trying hard to do something ....
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
New Kernel, App and TWRP finally online !!!

Changelog will be later online !

Enjoy Guys !
[Samsung Galaxy S8 & S8+ Cross Device Development] khanhbang2013:
Thanks bro!!!
[Samsung Galaxy S8 & S8+ Cross Device Development] monoik:
Thank you for the update. The app crashes when entering the RAM page for me. There seems to be a cast from bool to string somewhere according to the stacktrace. I've sent the info through the google play "feedback" feature.

I'm must say the new update is super smooth since I installed it. Great job Ace2nutzer!
[Samsung Galaxy S8 & S8+ Cross Device Development] Nakashima Taiki:
Does this kernel have moro sound control?
[Samsung Galaxy S8 & S8+ Cross Device Development] dorjan1976:
Thank you for the update, please fix for the next update if is possible to bypass secure folder because anytime I install kernel my secure folder I have to format it.
[Samsung Galaxy S8 & S8+ Cross Device Development] kidd25:
Better with this new update, but my 75% zram didn't completely disappear in lagg. Could a factory reset help? Or what do you advise? The app is working perfectly, thank you for correcting the "back" button bug. I don't understand the booster stuff in the display menu, can I get more information about it?

I gave the app 5 * for the app.
[Samsung Galaxy S8 & S8+ Cross Device Development] Nitrogenous:
I find input booster slider very useful. Kernel is smooth but if I'm allowed to point out minor issues I find there would be:

- 0.5s long hiccups from time to time in Netflix app that didn't occur on stock/nx/eas RZ kernel

- Apps loading time is quite long compared to others - however they behave smoother in.

My settings in kernel app are all default except 3000 mAh charging and 1500 ms input booster at 1.7ghz clock.

I tried setting up input boost for 3 seconds + 2.3ghz clock but no visible effect on app loading times.

Does it have something to do with flash memory tweaks in kernel? I/O scheduler?

I find forced gpu for 2d rendering in developer options that wasnt enabled before. Is that a part of kernel tweaks?

Thanks for another more and more polished kernel for testing btw!

[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Ah

I got it nice move there okey dev
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Meanwhile on S9 we can't even get GPU overclock right 💀
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
:v really?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
R55 works well so far?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
598MHz cap still. When trying to go above it gives time in state issue. S8 GPU with A2N is faster ☠️☠️
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
thank you for all your efforts Ace

just flashed it, wiping cache and dalviks.. took exactly 30 minutes to optimize 351 apps and completing boot up.. i'll let it charge and idle for a while coz this thing is pretty hot right now :D

i noticed bootup is much faster and scrolling felt smoother and snappier, not sure if it's placebo..

i'm going to need extra juice for today since i'll be working mobile so this will be the perfect time to test the hotplug on suspend and endurance
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes, it's all right, not placebo.

Boot CPU DVFS temp was increased from 65 to 75°C with the hope to need less time for compiling odex files. 30 min is still long somehow. I could try to increase temp even more, but the heat it's not good for the battery. (Over that long time)

And honestly I've added that hotplug feature with the hope to reduce battery usage while streaming music with the speaker with screen off, but even with hotplugged big CPU battery usage is still high. So i've to assume that the battery draining comes from the audio AMP itself, since it has a very powerful speaker.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
my phone ran out of battery after 13hrs 45mins

it was a pretty good day testing out the latest kernel + the phone with the real usage scenario :

i used bt audio omw to work, google maps for 1hr-ish, lots of whatsapp audio & video calls, 15 minutes mario karting, 1/2 hour-ish reading manga.. and it's on LTE throughout the day..

not the best battery stats but i tried using the phone without worrying about the battery level
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Broke s9 not got oc :")
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yes work so well my battery usage is like 4 hour without UV or something else tune maybe this day i will try UV maybe can get 5 or 6H sot
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
4th day seems completely different, i have 42% juice left before i leave work where i usually have 20% left 😎

sweeeeeet
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
at the end of the day my SOT was 4hrs 22mins, then i hit the bed at battery level 15%.. this morning i woke up and see that my phone is at 9%

i think i need to review what processes is draining on sleep
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah that's too much. Normal is max 2% over night in airplane mode. (Like it's in my case)
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
@ace2nutzer

i know, i don't use the device that much today, but i usually have 50%-ish near my lunchbreaks however i use it..

i never thought i could get 50% LEFT at the end my 9 to 6

now, the R55 is officially my favorite build 😆
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@Twiq

SOT 1:20h from 100% to 54% battery?

That's not optimal IMHO. You should get much more SOT. But maybe normal for an old battery.

Check those 2 things:

1. Deep sleep works? Maybe bluetooth prevents deep sleep.

2. How much brightness do you use?

For good battery life I suggest not higher than 25% if possible of course.

Latest release still good and stable?

At least for me it's rock stable, no app FC or random reboots.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
yea, i didnt use my phone that much that day..

deep sleep works i think but something is draining and i'm not sure which, maybe it's whatsapp telegram and discord running in background. and yes, bluetooth and wifi is always on, and 4g is on most of the time.

brightness is between 20-50%

R55 is rock stable on my end too, but i've been having some issues with NFC, everytime i try to check my cards balances it stalls whatever app that i'm using, not sure what caused it and and haven't looked into it so i haven't report it yet

i tried switching profiles, rebooting and opening the kernel control app but it still won't work..
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@Twiq

Later I'll check the NFC feature.

Best way is always to compare with the stock kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
i remember last time it was usable before the R54, but i'm not too sure if it's kernel fault.. but i'm sure it wasn't issue with the card too, as it's working fine on my wife's phone
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
i think my phone is getting really bloated now.. i have some free time somewhere this weekend and planned to fully wipe my phone..

do you think your kernel is compatible with the samsung gps patch rom released in 2022-08-18 ? talking about this one
