[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Alright look, if the shutdown temperature in this phone is 115C, I am terrified. Because that is MELTDOWN temperature lmfao. A mobile processor at that temperature sustained is going to die within days. I say this because I know it, as once, by disabling TOTALLY the thermal engine on my old Galaxy S5, I did reach that temperature at 2764MHz. That phone is extremely prone to overheating. But this phone? No. The CPU at these clocks produces far less heat than I’ve expected. It couldn’t go beyond 74. So regardless of the ambient temperature, this thing isn’t reaching 85C easily. Unless GPU is at 100% too. Also no. 2002 can’t be reached again. I need a reboot. It forces itself at 1950 most of the time after the recorded “throttling” event.

subsequent benchmark test is not enough to put the CPU in the spot I’m talking about. You have to install cpu throttling test and run it. All of sudden after some minutes, the little cpus will drop to 1950. And you will not be able to rise the frequency back up to 2002 in the kernel manager.

also CPU times are a poor indicator of events. You have to also install cpu float. That will make you able to keep an eye on the frequencies in real time with basically 0 toll on the system.

the 1950 does not happen while cooling down. It happens during the benchmark as the cpu is producing heat. The little cpu throttle down to that frequency and after the benchmark stops and even if you let the thing cool down, max little freq will be “1950” and you can’t set it to “2002” without reboot
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i did not stress the phone as you did so may be you are right, we measured different things in different aspects

and if the 2002 cant be reached again until reboot then probably it's a bug, will have to take a look at this

btw, we have a heat pipe in our note 9, so it should be better than the note 5 in terms of cooling, but i understand what you mean
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Not a simple heat pipe. It’s a pretty good vapor chamber. Our Note9 is pretty damn impressive.

Again, after reboot is set again if and only if apparently the phone wasn’t warm to begin with. Otherwise it’s stuck at 1950 again. It’s definitely either a bug or some mechanism that is very annoying to have around
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
yeah i think its a good one

ok, so i have installed both cpu throttling test and cpu float and played it for a while (4 times)

my default settings are: little max 949, big min 858 (for smooth transition)

and what i observed:

- with my default settings, it went up to 62C only

- second run with stock default cpu settings, yes, after reaching around 71C it went down to 1950

- third run, yes, 2002 couldnt be achieved again

- after that, i noticed the cpu temperature stayed at around 5xC when idle and wouldnt drop further, which should be around 36C when idle. so i closed cpu throttling test and cpu temperature went down instantly. (bug)?

- last run, it reached 2002 again

- i also found cpu float showed all 4 big cores at 2888 when idle. (bug)?

20211024 v2.12 released
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Ok so, when one core is being massively used (or cores aren't being used at all), the CPU boosts to 2886 as you know (because only one core was being used and the others were most likely at 1 or 0%). However technically all the CPU cores boost to that frequency. So no, it isn't a bug. It was just the CPU boosting for a second or so to the single core frequency (and CPU float displayed just that) because maybe some task was requiring that. So basically on single core load, all the CPUs boost to 2886MHz, but technically only one core is being used.

Also now you know what I mean with the 1950MHz bug. With this addressed, we can start moving.

@ykkfive ,that's my take on it.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
"Exynos 9810 is not able to make the big cores run at different frequencies"

oh really? have to check
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Nah nah I edited that. I was wrong cuz I checked immediately. It can do that but apparently when one core is being used it doesn't. Boosts all of them to 2886

@ykkfive

I have a very strong habit to edit stuff.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
@ykkfive

Also about the temp being stuck at 5xC, I don't know about that. I didn't notice. Could be a bug, just like the 1950MHz lock. The 2886MHz on 4 cores isn't a bug as I said before, it's just the CPU boosting due to single core load in idle
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
me 2 :D

but i just learned today from you, to reping someone. does it really work?

btw, i think it's not due to the 85C thing (actually should be 83C) for now at least. with my cpu settings, it went around to 62C and still throttled like a roller coaster although both of the cpu freq were max as shown in cpu float (in my case 949 and 1794). I have also raised the 83C a bit to 88C but it didnt help

so... it must be something else (everyone knows...) that prevent the cpu to stay or go further
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I don't get what you mean with the "does it really work"

Either way about the temps, yeah. It's clearly not temperature related. There has to be some other factor involved. I was considering some sort of power throttling (like if the SoC consumes more than like 8W, it throttles frequencies down) but I don't believe it's that. Maybe it has some boost timer like Intel CPUs?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
cant tell at this moment but i have seen somewhere in the sources that the power is taken into the ac when deciding something, cant remember what's that though
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Looks like mastering, discovering and unleashing the Exynos 9810 in its entirety is going to be a long and interesting ride.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Hey man @ykkfive, i curently run on latest Dr.Ketan Q17 ROM also BeastMode kernel V.154. Now, i've tried to install this latest kernel V2.12, but it was failled. My kernel still showing BeastMode V.154 one. What should i do man?

This is my software info screenshot and logcat:
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
fuf5? i installed it without problem , not on q17 though

boot.img or zip file?

any error msg in recovery?

and which version of twrp? mine is 3.3.1.0
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Correct, fuf5 in AP.

I flashed zip file.

No error message at all

But

My TWRP ver.3.2.3.5

Is it affect the installation?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
If I'm not mistaken the recommended version of TWRP for Note9 Exynos is 3.3.1.0.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
My bad 🤐
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
yeah try 3.3.1
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Yeah it works :D
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Just use 3.3.1.0. Don't use anything older or newer. 3.4.0.0 has issues too.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Alright Sir, very useful nice tips 😃
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ken1731986:
hi mem, you can build to galaxy s9 plus kernel

thanks
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
sorry, forgot to mention

set the io scheduler to noop as to increase the ext4 performance
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
sorry man , but i am afraid not coz i dont own a s9 plus
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Is it increase SD Card performance too?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
@ykkfive

Alright so yeah. 2002MHz dropping to 1950 and not going up again is definitely not temperature related. Looks like a timer. I put min and max little core frequency to 2002 and cool the phone CPU down to 22°C and yet the little cores I found them at 1950 and couldn't put them up again.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
I think this noop i/o scheduler is more like batterysaving CPU governor. It uses lowest 650Mhz at big cores and 715Mhz at small cores more than any other i/o scheduler. Usually, other i/o scheduler will make 1794Mhz at big cores and at small cores more active.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Hey man @ykkfive, could you fix the GPU Driver? It will always kicked back freq by itself to only 260Mhz to 338Mhz that can be used for gaming. Although i've put min to 455Mhz and max 572Mzh, it will remain 260Mhz only that can be used. Even, my GPU degree not that hot (it is 48C only)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i didnt check but i have read that long time ago noop is better for non mechanic disks
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
hey i don think so

i tested with starting the benchmarks at higher temperatures, 40 and 50. it dropped to 1950 earlier so i think there is no timer

u may try
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
oh really? i didnt check about this before
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
it seems those manager dont reflect the real status, nor the gpu time for some reasons
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
No. It’s the manager not being able to control the DVFS. The DVFS is doing as it pleases. If you disable it in sys/devices/platform/17500000.mali by removing read and write permissions from “dvfs “, “dvfs max lock” and “dvfs min lock” you will be able to use the frequencies you set up. (You have to use a root file explorer. A decent one). Unfortunately it’s a temporary solution, as it resets every reboot.

I assume DVFS is also the thing dropping frequencies for no reason on the CPU. If it’s not a timer nor temperature related
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Hmm, but it seems like true status. Cause everytime i force minimum freq to 572Mhz, it will also increase significant fps for awhile and show correct increasing freq too. But it just for a while, it won't retain.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Okay ill try it. All i know, to let DVFS not reset by itself is by making init.d script or via HKTweaks at init.d section. But unfortunately in android 10, init.d folder is not able to be made yet.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
Confirmed

Disabling DVFS by revoking all read and write access making GPU run at any freq we set in hKTweak (even 572Mhz all the way long). Plus we need to disable game booster, game optimizer and friends. Those thing make instant re enable DVFS by itself (not even until reboot).
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
use magisk, post-fs-data or init.d module
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i thought he was talking about the gpu freq not shown correctly in those kernel managers

by looking at time_in_state you will find the real numbers
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i have read similar things before, so good to confirm it

l will let you guys to explore this. thanks
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i will go back to the sources

so in the mean time, pls discuss and share any thoughts, findings and results

but also please note that, since the introduction of cpu/gpu oc things in the past was a failure which degraded the overall performance, i decided to drop those tweaks and started over again, which was reflected in v2.10 i believe. so chances that some of the controls, not limiting to cpu/gpu oc, may not work properly, were partially done or have been rolled back to stock basis

please be patient and hope that they can be solved later

thanks
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
The GPU frequencies in my experience are shown correctly. The problem is that you can't control them when dvfs is on. I think you should disable both CPU and GPU dvfs. It kills performance and is probably the culprit behind the 1950MHz bug
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Just had a random reboot while the phone was in deep sleep (screen off). Again, it's a fast reboot. The phone does not turn itself off and show the samsung galaxy note 9 logo. It goes back to the Samsung glowing logo and then boots. Some settings remain applied.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] trevinutomo:
i think you must be in unstable ROM i'm afraid. Cause in Dr.Ketan ROM this kernel work fine.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I am on Alexis ROM 3.0. And other than that it doesn't give me any issue. It isn't unstable, I guess it's some compatibility problem. After all, it's still a ROM different from the stock One UI 2.5
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
most likely rom issue then

btw, i have heard that alexis 3.0 requires a permissive kernel, how can you install it over this kernel?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I have no idea. I installed the ROM first, let it boot and then installed this Kernel by going back in TWRP. I had Selinux on enforced for a while but recently I put it on permissive on this kernel. I guess it managed to work because the kernel still supports permissive. This ROM was my last hope to revive my phone after I accidentally deleted the stock OS. So I don’t care if it was luck or anything else, I am glad it works on it lmao
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i see, cool
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Admittedly I wonder why I didn’t install Dr Ketan ROM or Noble ROM or Lineage OS instead of this one. But it’s probably because I was highly distressed there, and knowing that I had positive experiences with the Alexis Rom (saved my S8 too. Lineage failed me once), I was super sure Alexis would’ve saved the day.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Your philosophy, at least to me, seems like the one that puts as a long term objective building a Kernel that guarantees maximum performance but at the same time great efficiency, which is pretty respectable.

As always, I am fully open to test new builds. However you really make the safety side sound menacing lmao. What did you change/add exactly other than PELT? Is the possible safety issue you are talking about coming from the increased frequencies? What kind of numbers are we talking about? I can test, but I'd like to know what I'm dealing with first.

If you increased frequencies to the point of possible instability on some devices, 7xx and 22xx scores on Geekbench 5 are pretty low. Because I'd expect to get over 2300 and maybe even 2400. I have all the tools I need to keep the temperatures under check, but even then, just what did you do that caused the phone to throttle so much? I think you are aware that the peak frequency this phone can handle before hitting an efficiency wall is 4x2314MHz on the A75 cores. 2106 being the more conservative choice.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Because I am considering to test these builds, because as always, I can provide a lot of feedback and analysis.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
yeah you are right, i should have mentioned what the changes are. anyway i have updated the post above. pls read it again
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
yeah i know, and that's why i want more to join. it's impossible for me to do all the tests alone
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Then If you are okay with it I can start testing immediately. These changes, except for the PELT introduction, don’t look like they would be cause of serious instability to me (Imagine my phone gets soft bricked or hard bricked as soon as I install the test build LMAO). But it really shouldn’t be the case. Either way if these are all the changes you included, I can start testing as soon as you want me to.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
With the current changes, a Geekbench 5 score of 23xx might be possible as well. I gotta test. Hope it won't kill or brick my phone though, because that would make me unable to test anything.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] CyderXDA:
yeah I know but it takes too long to load a movie and it even can't play
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
sorry i cant do that for

1 it might cause conflicts with others in your rom, can result in boot loop in the worse case

2 i cant modify others' works

so better ask your rom developer to modify it if needed
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Detonatte:
6-7 hours think.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
that's weird, as i said there might be some compatibility issues with Q16

i received feedbacks that there is no problem at all with other roms (UE5) like devbase or noble rom

as i mentioned Q16 is UE1 based but this kernel is based on UE5. so at the very beginning (it was on stock UE5 before) just after i flashed Q16 i noticed some problems. i remembered during Q16 installation the vendor partition has been overwritten by Q16's UE1 vendor.img, so i flashed UE5's vendor again (note it wiped the data partition). and since the system img of Q16 is also based on UE1, with all build.prop etc telling the system it is a UE1, that could played a part in the safetynet issue, so i replaced some of the files from UE5, till now it works properly

so, would you like to try replacing the files from UE5 and test again? else, and if you want to stick to Q16, then you may perhaps need to go back to his kernel. it's up to you

btw, which rom were you on before, UE1 or UE5? stock or custom rom?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Detonatte:
What replacing? Ok, test again. What do u have to do?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i will give you a zip file later today, in the mean time, please do a complete backup, EVERTYING, including data and sdcard, efs, etc

btw, do you know how to get the logs with logcat? if so turn on your phone and idle for 5 mins and then send me the log

you didnt update bootload nor modem before?

i think you better flash an updated firmware , because older bootloader can cause problems, while older modem can cause loss in connectivity

but of coz, at this stage, may be you did not notice anything but as a normal user sometimes it's hard for them to see what's wrong. although they can still be used without major problems normally, an upgrade is suggested

Hello Dev

Your kernel is also compatible for Alexis ROM 2.8 OneUI 2.5 FUE5, thank you kindly.

thanks for reporting mate, enjoy!
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Detonatte:
"you didnt update bootload nor modem before?"

NO! Only flash Q16! Your kernel is for version N960FXXS8FUE5 from June 3, 2021 and Q16 is with version N960FXXU8FUE1 from May 19, 2021. Dr.Ketan no update for last version :(
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
that's true. this kernel is based on a newer version than Q16, and this causes some problems for safetynet/cts profile

but as per instruction, u should install updated bootloader and modem according to dr ketan's. yours are quite outdated, but it doesnt necessary mean this can cause serious problems. however, it is suggested to follow the instructions laid down by the developers to ensure a proper setup

anyway it's up to you. i used to use an very outdated bootloader before without problems. so what do you want now? do you want to update the bl and modem first and see if problems get solved first or what?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
same for me. good luck
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I am just being paranoid. Technically the worst that should happen is the phone boot looping when the Kernel is not compatible or not working properly. I mean, the brick case may happen if said Kernel has some crazy stuff going on, like an Overclock that is out of this world, which is not the case for this one. It should be relatively safe.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
i wont do those crazy thing, remember my phone is gonna die? haha
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Nah it ain't dying lmao dw my man. Overclock is safe as long as you know what you are doing. I have years of experience overclocking phones (started off with my old GT i9300. Brought it from 1,4GHz@1,28V to 1,7GHz@1,35V. All frequency steps under 1400MHz I've also undervolted by about 105mV. That Exynos 4412 is still monstrous to this day. I couldn't do 1800MHz even at a very dangerous 1,5V. The silicon hit its limit at 1704.

Besides, with the 9810 you can't overclock to begin with, you'd simply get the frequencies Samsung advertised and then underclocked lmao.

I'll gladly wait for optional overclocking if you will ever include it. I fully support the optimizations and inclusions you are currently doing, which is why I am offering my contribution.

Edit: Best way to include OC in a Kernel is to make said Kernel boot at stock frequencies and offer the user the possibility to overclock. But it is entirely up to them and it's their responsibility.
