[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
So finally I decided to try your kernel, as I see great potential. Noob question here, but I am not sure if the kernel has been installed correctly, please see the attached picture. With ExKernel manager, I am able to set the I/O governor to noop, but not the CPU governor. As well, in the phone info it does now show BM Kernel, but only the stock kernel. Finally, I cannot find the RGB fade option. I am using Dr Ketan's Q17 Pro.

Thanks in advance for your help :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] n4f:
hi, this kernel has rgb option, can you add other options too? image from mi 5s plus floppy kernel.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
it's not bm v2 kernel. try twrp 3.3.1.0

if success it shoud show beastmode kernel v2
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
what particular options?

currently i am focusing on performance, etc. so these kind of features can only be reviewed at later stage
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] n4f:
sorry for my bad english. your kernel has already rgb option. just others (saturation contrast value and hue) not added. thanks by the way.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
no not your problem, my mother lanugage is not english either 😄

i just dont know what we have right now except rgb so I asked what's missing (ps i dont use all the functions myself)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Thank you, it worked with twrp 3.3.1.0. Looking good so far for a daily driver, with slightly better battery management.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
this is the farthest point I can reach for now. GPU can be squeezed more I think, like 7k.

BM v2.10 Note9 N960F Alexis 2.9
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
how's your read performance now? still the same around 6xx?

there's more to come, beating yours but you may need to sacrifice your insane disk read/write
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
I saw another problem with newer versions of your kernel,

Apart from the decrease in disk read and write speeds, I also saw that the latency required to access the disk increased.

here is the new benches from 2 minutes ago.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
cant maintain the performance in all areas tbf, like memory speed is relatively slower, but i have seen 19x in multithread once (not yet released)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
ah I see, also v2.12 feels faster than v2.10
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Well this memory performance is around 10,000 higher than mine. How. This would make me able to go above 460,000 and match Kirin 980.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
20211120 - v2.14b2 updated
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Alright. I will immediately update. What are exactly the changes? I am curious so I can test more @ykkfive
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
listed in change log, but the major change except pelt when compared to the previous release was hz increased from 250 to 300, should increase ui responsiveness

but still delievers better performance than the previous one
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
removed due to an old minor bug was introduced, there will be no sound sometimes after a reboot

sorry about that coz this problem will not happen every time after reboot and i just discoved this happened again
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
updates: v2.14b2-FIXED released

for those with v2.14b2 please download and install this fix

thanks
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Thank you for your efforts. Installed and testing.

Should wq_power_saving be enabled or disabled?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
it should save some battery while trying to maintain performance if enabled

edit, if in doubt, use the default settings and it should be fine
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
btw, in case you want to see some numbers, here they are with 2.14a (private build) and 2.14b2 (max observed by me and my tester TechNoobForSale, not guaranteed and results may vary a lot):

FOR REFERENCE ONLY

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
456K?! How. Why are my memory speeds so much slower than everybody else lol. I score 80,000 Memory on AnTuTu. But everyone is at 90,000. Is it because I have everything on EXT4?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
456k was scored by you, you sent me the screen cap 😅

edit and i am on ext4 too, no time to convert to f2fs yet
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Excuse my dementia @ykkfive :cowboy:

My highest on 2.14b2 FIXED FUH1 was 451,667 but I was on 2960x1440. Not reliable. I'm going to test more. Maybe I can get 457,000 :cool:

But again, if I was on F2FS and if I scored 90,000 like another user in this thread instead of 80,000-83,000, I'd be able to do 465,000+ and beat Kirin 980! (My objective to be honest). Glory to Exynos 9810! We are going to take all of its hidden power and make it ours.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
How you are getting so high scores? Do you apply any specific settings to the kernel?

I am getting about 370.000.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
That score is very low and is the same as stock firmware average, and actually on stock I once scored 400,414 in the past. Even on stock Kernel settings I still get 412,000 at minimum. I highly recommend you to keep an eye on phone storage left, ambient and phone temperature, because this phone likes to throttle hard as soon as it reaches the throttling threshold.

What ROM are you on? What are your Kernel settings? And also the previous questions. If you can answer.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Send the AnTuTu V9 and Geekbench 5 scores and Kernel config with all the other stuff if possible. Because this is very abnormal.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
My highest score was 395672 in Antutu 9.2.2 and 714 /2251 in GeekBench 5.4.3 on Galaxy Note 9 with Alexis ROM 3.0 + Beast Kernel 2.14b2 FIXED FUH1.

I Use latest EX Kernel Manager, Big Core: min 741 max 2964 Little Core: min 715 max 2002, I/O internal and external is NOOP + no wq_power_saving, ex4 memory.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
I have idea that maybe cooling system is damaged :) or Some software causing low results or this is the issue of settings. I am sorry but english language isn't my native language :0
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Thank you all for your replies. I am on Dr. Ketan Q17 rom. I am attaching geek bench scores and ex kernel settings. For some reason my antutu crashed this time before I completed the benchmark. For your info, I run 2 SIMS, with Bluetooth always on and the only software running is call blocker. I do not think though that these are affecting performance.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
2964MHz max M3 Cores? This Kernel goes up to 2886MHz only. There is a value about 2964MHz but it isn't used and therefore can't be set normally.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Bluetooth on and Plane mode off noticeably increase the heat production of the phone.

But that is a side note. Your EX Kernel Manager settings are VERY unusual. The Quad Core mode on this Kernel can go at 1794MHz only. Yet yours is 1924MHz. This might lead to overheating with poor cooling. Also "Variable" as minimum frequency? Never seen before. I suggest you to use hKTweaks. It's a specialized Universal Exynos Kernel manager. It isn't on the playstore but you can find it easily on Github I think.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
You right👍
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Thanks a lot for your feedback, I would appreciate if you could upload a screenshot with your settings. I will download hKTweaks, however I did not adjust any settings in the Ex Kernel Manager, these came in by default.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I am on Alexis ROM 3.0 which might as well be handicapped a little in performance (As you can see I have LITTLE cores at 1950MHz instead of 2002MHz because ROM hard locked it at 1950MHz and I only need to reboot to make things go back to normal.

Resolution is 1480x720. Phone GPUs are relatively weak so 2960x1440 only kills performance. Full HD+ too. Also you want to download Root Browser and go in sys/devices/platform/17500000.mali

Once you are in that folder you want to long press on dvfs, dvfs max-lock and dvfs min-lock and go on permission. You have to remove all the write and read permissions from the checkboxes and then save the changes. This resets at every reboot but once you have done it it allows you to have full control over GPU frequency and therefore you will get a gaming performance and stability boost. A big one. Also benchmarks will improve

But again, if you don't keep an eye on phone temperature, it might be overheating and that's why it scores low in benchmarks.

Remember that Big Core Frequency in Kernel managers only refers to Quad Core frequency because the M3 has a weird scaling like Intel CPUs

In this Kernel it's:

Single core: 2886MHz

Dual Core: 2314MHZ

Tri and Quad Core: 1794MHz

It's a very big drop. But in the future we will probably increase Quad Core frequency to get a nice performance boost as long as temperatures are in check.

Note well: That's my everyday profile. In benchmarks I put minimum CPU and GPU frequency as high as the maximum so that I lose no performance at all at the cost of battery and heat production but I know how to keep my device cool for testing (I have a dedicated cooling system that keeps chassis <15°C at 20°C ambient). But the advantage of having a custom Kernel is this. Control over maximum and minimum frequency. You can adapt it to your needs, always. Also PELT in this Kernel is pretty aggressive so even with my very low minimum frequencies, daily usage is unaffected. It scales up very fast and stays there very long.

It's not energy efficient...at all (But future optimizations will fix). But it's pure power nonetheless. And I am one for power. Exynos 9810 has a lot of it to be unlocked. Samsung made us pay for a phone that has been limited. Did you read the review of the very respectable Andrei Frumusanu on Anandtech about Exynos 9810?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Man thank you for the screenshots and feedback. Will try the new settings of the screenshots asap and bench again. Regarding anandtech, yes I had read that review and was surprised on how samsung messed up so bad on the kernel optimization. This thing surely has power, but they did not put effort in optimizing! Will report back. Glad to have you, the developer and the rest of the community being so active :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Not gonna lie, at least to my eyes, ykkfive is the only active developer (And XDA calls him inactive) that is supporting One UI 2.5 based ROMs and offering a Custom Kernel that will slowly integrate all that Samsung didn't and that will release the true power of the 9810 (Superior to 9810 and nearly equal to 9820).

There are solutions for Samsung Experience based Android 8.1 and One UI 2.0 but again, we all are on 2.5. Those on 3.1.1 Port ROMs have no choice at all but to stick with a normal Kernel too.

Remember to turn on Plane mode for benchmark and turn off Wi Fi, and put minimum frequencies same as maximum. Keep the phone cool. It's very important. The CPU starts to throttle when 75°C internal is reached (This phone actually runs very cool on average but the throttling threshold is again, super conservative. Thank you Samsung).

The community is active like you said. Just not in the areas I wished lol. I love Custom Kernels.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
there is also a control for when you want the cpufreq scales up for daily usage. unlike TechNoobForSale i dont set the min freq to the max during benchmarks and i dont have a cooler but the overall results were about the same, so it did the job well by cooling it down
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Higikata:
th
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
no problem mate

in fact they (one of the moderators) had contacted me long time ago since i was not being active and asked if i would like to change my status to inactive to reflect it and i said yes

until now i didnt ask for a change for the status and i believe they will do so if i request for it, but nevermind, it's not important. i am here only to keep this note9 alive by cherrypicking tweaks and put them in this kernel. as i mentioned early it's more than i need for my daily usage already, the rests are just for you guys
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
no problem mate, my native language is not English either

and, no need to chase for the results except you are a speed chaser or gamer, the phones have different asv values and different level of deterioration
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
When the developer is....based

Ykkfive, either way, Exynos 9810 is very flexible according to Andrei's analysis. So you might as well give yourself a very balanced profile and offer people more options to increase performance or battery life if they want. And this Kernel is definitely already evolving to provide a completely unleashed Exynos 9810 experience.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
This is my benchmark result. I I'm wondering why MEM and UX Result is low :(. In my kernel manager I did : cpu: Big core 741 min / 2886 max in LITTLE core min 714 / 1950 max, I/O NOOP, GPU min 260 / max 598.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Your phone visibly heated up. CPU score is lower than it would be at peak when temperature internally is below 70. Memory performance highly depends from cache frequency/CPU frequency (it has to be one of the two). So if the CPU frequency drops due to throttling, so does memory performance. UX performance is affected by resolution and CPU status in a benchmark like AnTuTu. Not GPU, unlike the actual everyday user experience, as in modern Android versions the screen is composed by the GPU at all times.

Also remember to rise minimum frequencies through a Kernel manager before gaming or benchmarking. It helps a lot.

Besides, you forgot to edit the sys/devices/platform/17500000.mali dvfs, dvfs min lock and dvfs max lock files to remove their permissions. That took around 4,000 points away from your GPU
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
According to your advise with: " Besides, you forgot to edit the sys/devices/platform/17500000.mali dvfs, dvfs min lock and dvfs max lock files to remove their permissions. That took around 4,000 points away from your GPU", I did it and made some tests and ultimately i reach 411467 points in total in antutu v9.2.0, but main problem is high temperature of cpu and I think if temp of cpu was low, overall cpu's points could be higher. I don't have idea how to decrease temp in cpu, also I think that cooling system in my Note 9 is slighty damaged or have too low performance to decrease temp in cpu or some hard software running in background. Hmmm
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Install a software called "Termux". Run it in landscape mode. Wait for it to install itself after you open the apk. Type "su -c top -d 2"

That command will display all the processes running and the respective CPU usage. So you can identify the culprit, if there is any.

As for the internal cooling system, I have no idea how could it possibly get damaged, aside from a pretty violent impact with the ground. There is a variety of ways to keep the CPU cool. But I, personally, for testing, use the FunCooler Pro. It's a nearly universal smartphone cooling pad. It's not a normal fan. It's like a fridge, but on the back of your phone. It nearly eliminates throttling from games and benchmarks.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
what's your cpu temperature when you start benchmarking? for me it's about 32C usually

edit i don have a dedicated cooler
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
30-32C

Here is my latest benchmark results.. Alexis 2.9 + BM Kernel v2.10
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
What are your settings in Kernel?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
I used Kernel 2.12, 2.14, 2.14 FIX and i have better overall score on 2.14 Fix. I have idea that Kernel 2.10 is more better adepted if come to benchmarks. I made some tests and scores GPU was 128000-133000, CPU 115000-118000, UX max 91000, mem 66550-69000 also i have ext4 file system and I use security software for POLAND XEO because I am from Poland and I live in Poland
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
just cant beat your disk read write, but that's not my problem 😄
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
he got a special weapon, a great, new mb replacement!
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
fortunately you didnt try 2.10, which produces the best read write so far as reported, else you would blame me for slower ext4 performance after updating the kernel, haha
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
well to be honest, i didnt expect ppl will be so interested in the scores. i only wanted to show you guys what could be achieved in the latest version after adding some new stuff, i didnt mean to make noise

but, anyway, i am happy to see ppl coming back to discuss about this kernel. do remember, your inputs and supports are invaluable

i hope you all will enjoy
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Personally apart from the scores, I am mostly interested in squeezing as much performance as possible, as the UI smoothness is not the best, at least for me. I have the Note 9 for 3 years now and I really want to keep it, as all the new phones are lacking features. Appreciate your work!
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
Cpu

Yeah my mb was replaced 1 month ago,

And my kernel settings

Little min max 2002mhz

Big min 2886 max 2964mhz

(you can set with exkernel manager)

Open hktweaks go to GPU section, make the governor Booster, set min max both 572mhz. Set gpu high-speed clock to %1.

Antutu should be run always on plane mode. Also I put my phone to freezer to prevent throttle 😂

Use Lspeed v 2.5.1.4 and go for gpu section select all and set performance. This will boost GPU and UI score significantly
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Matrix1001:
I also appreciate work to improve ours Note 9. I had such an idea . I placed a wet cloth in the freezer so that it serves as an external cooling to Note 9 while I will do a test :):):):):)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Would be interesting to see a test without and with the wet cloth 😜
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Ex Kernel manager allows the 2964MHz frequency to be used? I'll use your settings here and try to check if I can go 460,000+ . Damned Kirin 980. I'm coming.

Another question, did you disable Fsync and CRC? Those slow down performance but protect data in exchange. I still have Fsync on as my Note9 is still my main device. I wouldn't enjoy a crash corrupting my stuff. I have flashbacks from my old GT i9300

To be very fair I am afraid of this L Speed thing too but I installed it anyways and applied a bunch of tweaks.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Then you will be very happy to know that as of now this Kernel is still at a far cry from the full performance this device can offer. Unfortunately Android 9 and 10 limited GREATLY development freedom when it comes down to this device.

The CPU Quad right now goes still at 1794MHz. But Samsung engineered the M3 cores to go up to 2314MHz when all 4 are used. That is a 29% increase in clock speed that would bring the 9810's CPU above a Snapdragon 855+. About the GPU, a 775MHz frequency step should be enough to make us match the 9820.

This SoC is a beast. But it's caged. But thanks to ykkfive and the efforts of you all in providing inputs, we are starting to break the bars...and this thing roars.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
Yes I disabled CRC and Fsync too.

2964mhz is used but you can't see in hktweaks or exkernel manager.

you can check it from somewhere in root folder.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I know there is a folder in the sys that states that maximum frequency is 2964MHz. But I can't set it in any Kernel manager. And CPU Float does not report 2964MHz either. I am pretty sure it uses 2886MHz and Ykkfive never mentioned that his Kernel goes above 2,89GHz either.

Besides, I tried that L Speed thing and my score on AnTuTu dropped to 403,000. Never again lol. Disabled the "tweaks" in app and then uninstalled. Hope it didn't ruin anything in my system. I don't trust this stuff because before installing it on my Note 9 I installed it on my S5. I applied the main tweaks for CPU, GPU and I/O and now it constantly crashes some time after boot.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
After uninstalling L Speed, I randomly got my best score so far. I/O is, once again, limiting me. Might be F Sync's fault. I will check later.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Even with a proper L Speed setup, I noticed no improvement in performance on my phone. However I did notice it on my older devices. My memory for some reason is just slower than ModernDay Cowboy. Maybe he uses F2FS File system.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Just managed to break the 460,000 barrier. CPU underperformed and the theoretical max is around 468,000. But my goal was to get beyond 460,000. This is like, extremely near to the limit of the Kernel as it is. Next step is further overclock and more optimization.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] livagoth:
Congrats! Did you get an external cooler to achieve this? I noticed that your temp readings are pretty low for this chip.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Correct. I already specified it before that I use a FunCooler Pro from Xiaomi to keep my phone as cool as possible. A fridge could probably achieve better results but I am very hostile to the idea of putting my phone in such an environment purely for performance reasons.

Also, that is not chip temperature readings. I wish. That's merely the battery temperature. Internal CPU temperature can go well over 60°C and can peak at 74°C on AnTuTu Multi Thread section of the CPU benchmarking. With the cooler it probably can't manage to touch 70°C, but there is something throttling it down.
