Look, according to my calculations, bringing the GPU to 598MHz (Originally intended GPU frequency for the 9810) and CPU frequencies to respectively:

2886-2964MHz for Single Core (Originally intended 9810 Frequency for Single Core is 2886MHz)

2496-2652MHz for Dual Core (Originally intended frequency is unknown)

2314MHz for Quad Core, which is actually the originally intended quad core frequency. It's not even an overclock. It's just taking what they took away from us back. They underclocked it all the way down to 1794MHz.

And we will EASILY be able to MATCH and maybe even beat the Kirin 980. There is also a chance we get closer to the Exynos 9820. This is just how much potential the 9810 has buddy. It's about mastering it. And if we manage to push the GPU to 775MHz? Yeah it's just next generation experience at that point (We might be able to beat the Mali G76 MP12 of the Exynos 9820, because even though it runs at like 800MHz, the amount of cores it has is much lower). But you'd have to rise the throttling point at 95°C for that.

The Exynos 9810 is monstrous. It was held back, restrained. It was way too powerful and Samsung couldn't manage their own processor's greatness, so they simply reduced clockspeed. It's all in your hands whether this processor finally reaches its true potential or not. Best of luck. Believe it or not, the time you are spending on this processor is going to be worth it.

Oh yeah actually I wanted to give you a little extra.

Kernel version is 2.11c6

Storage Performance:

Sequential Write (4MB): 127,26 MB/s (Max 172 MB/s)

Sequential Read (4MB): 284,62 MB/s (Max 785,72 MB/s)

Random Write (4KB): 2,38 MB/s (Max 7,83 MB/s)

Random Read (4KB): 11,78 MB/s (Max 813,8 MB/s)

Memory Copy (4MB): 11,82 GB/s (Max 14,6 GB/s)

These are the most detailed storage benchmarks I can give you currently.

thanks for your info

let's see what happen but i have to fix the ext4 first and it was due to the updates, either ext4 or kernel or both
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Karolis LTU:
Hello I wanted custom ever sonce I rooted my SM-N960FN/DS but was super sad after I found out about KNOX triping and being unable to use Samsung Pass and Pay anymore. Just wanted to ask does this disable TIMA and KNOX trip and if yes does it work with this version of ROM?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
here is the benchmark of devchecks. v2.11c6

Cpu is normally low (due to my Lspeed battery tweak)

Ram performance is normal as stock.

Storage write speed is amazing. (it was around 200-210 on v2.10) I saw 240 sometimes.

storage read speed is 100-150Mb/sec decreased. (it was around 550 on 2.10)

ps: may you publish the next version of your kernel as like the current one as FUF and FUH seperately?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
unfortunately once rooted, knox tripping will be triggered and you will lost some of the Samsung's features. however there are some workarounds provided by some custom roms or magisk etc

personally i don use any or them but if i remember correctly samsung pass is possible

may be anyone can give him some suggestions pls?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
needs some works with ext4 again, it happened after upgrading the ext4, ie v2.10

while cpu, gpu and mem will be revisited after fixing the ext4 thing

and yes, i will provide 2 different versions for a certain period as i can see there are more ppl with fuf5 including me
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Karolis LTU:
So this kernel doesn't mask KNOX? I was wondering because there's a lot of custom kernels here that does but their either outdated or for Pie and I'm on 10, won't you consider adding it? Literally if their is anyone here could you be so kind as to offer some custom kernel that does mask KNOX and would be complatible with current or latest vanilla ROM? Thank you.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] JC1126:
I've finally managed to correctly flash AlexisROM, so I slapped your kernel in it, and format Data & Cache to F2FS, and here my Benchmark Results
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
There is no such thing as "Masking Knox". There is only resetting the Knox counter. Whenever you flash unofficial stuff into your phone, the counter is tripped. I heard of some Kernels resetting that, but that's about it. What you mean is maybe masking the root in OS. But that never personally worked for me.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
yeah it is true, I formatted my note 9 and do the devcheck.

my read speed is back to 550mb/sec again,

do not flash v2.11c6 over v2.10.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
as far as i know, once knox is tripped there's no way back, at least for now. some roms provide modded samsung apps like s health for rooted devices but not all samsung features can be reclaimed
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
that's cool, mate
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
just be patient for now, but of coz you may downgrade to v2.10 atm

btw, he's gone v2.11c6 with f2fs
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
yeah once the efuse is blown you can do nothing, except to hack the app or framework but there's no guarantee
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Karolis LTU:
Well does this ROM Reset this KNOX Counter or nah? As Hiding root from system that's working perfectly nice.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Firstly, this is not a ROM. It’s a Kernel Developed to work with One UI 2.5 based ROMs. As far as Knox reset is concerned, I don’t think it resets it. That’s something a ROM itself may or may not do.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Karolis LTU:
I see would like OP to reconfirm it.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
@TechNoobForSale is right, that (over 90%, nearly 100% with 1 exception which has been implemented to this kernel) has to be done with the rom makers by modding the apk or jar files, or via magisk, it's modules, etc
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
ps if you simply mean this knox 0x0, it's done by rom modders

Can I ask if this kernel can be used for N960N, thanks
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] otaking71:
i'm finally back..haha..life has been kicking my ass...glad to see others picking up and chiming in.

As with regards to the gpu, this thing _SHOULD_ in theory be able to get into the 800+ mhz range as arm was touting 850 mhz on an older process for this gpu design. YKK knows my thoughts on what needs to be done to fully utilize it. There's _DEFINITELY_ a stupid amount of performance left on the table.

The main thing that still bugs me is how none of the kernels seem to behave the consistently across multiple kernel managers. I got a partial compile, last time I spoke to ykk. I'll eventually figure out how to get a compile so I can contribute more technical stuff.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:

welcome home, no 7 cristiano ronaldo!

oh, sorry... haha

yeah that's great and i knew you dont want ppl to give you a hand and throw everything to you unless you have to, coz you will try it youself and look for a solution first. am i correct? (say yes pls or it will be embarrassing...)

tbh it will be a boost since my note9's screen turned greenish before and i really scared to perform any risky experiment on my note9...
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
To be honest I think the green tint is not related to the GPU, but rather, the display itself (my S8's broken display has a very intense green tint and it doesn't display anything, however the phone works and is responsive). I've experienced GPU instabilities on phones before and they manifest themselves as artifacts or total system freeze (More often than not the second).

You can tell a GPU-issued crash from a CPU-issued crash because the GPU crashes WON'T automatically restart the phone, while CPU crashes do. Either way don't even bother lmao. Pushing the Mali to 850MHz on this thing is going to cause the temperatures to rise very high, unless there is some miracle in the architecture I'm not aware of. The highest I've seen is 775MHz and I still believe that is a very pushed overclock, but 598MHz isn't enough either.

Basically what you should do is rise the throttling threshold to 90-95°C. That is going to increase our headroom greatly. As of now it's at 70°C, and it hinders performance a lot (during heavy gaming my phone will start to lose performance extremely fast due to that).

Either way we should keep GPU stuff for later because the main problem in the Exynos 9810 is how stupidly underclocked and hindered the CPU is.

Basically like your roadmap states. You wanted to add F2FS support, you did it. One of the objectives are complete. Now you are working to fix the ext4 and system stuff, then we should move on CPU related stuff and then GPU.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] otaking71:
lol...ykk.. you are indeed correct.

technoob...which kernel was this? and did they actually put in correct voltages for those speeds? if they just said eff it and did max voltage then you'd definitely run into temp issues. it would be crazy if they did it with the joke of a stock voltage table. overclocks won't help this cpu much at all. the problem with this chip is that it runs hot and _NEEDS_ to be fed. The biggest gains are going to come from the ram tbh. With that wide a core...on top offeeing agpu...thatyou need more memory performance.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Alright so. The Kernel that reached such crazy clock speeds for the GPU was the Zeus Kernel (Private Edition). However it only runs on the Oreo OS and the overclock are way too pushed and not all devices could handle it, causing phone reboots, which confused people.

Also, you are mistaken. And I need to specify some things.

Firstly, Exynos 9810 has been underclocked by Samsung, which means that by rising frequencies, we are just getting back what they took away from the device we paid for. The M3 cores are indeed very, very power hungry. But you have to expect a power requirement and heat output increase when doing intensive tasks anyways, on any device. The 9810 was meant to run at 2.9GHz in single core, 2.5GHz in dual core and 2.314GHz in tri and quad core. It has been underclocked to 2.7, 2,3 and 1.8 respectively. The small cores were meant to run at 1.9GHz. They got underclocked to 1.8 too.

According to my expectations and estimations, the Exynos 9810 would be able to match the 9820, clearly while consuming much more power, but not as much as you would expect! To my eyes, the 9810 was an amazing processor. Mistreated by Samsung so badly. The potential is off the charts. RAM can only yield an improvement if overclocked. This device already has plenty of it.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] otaking71:
The m3 core is effectively 6 instructions wide. Yes it has 12 pipelines, but it can only feed 6 per cycle. At that rate, your memory bandwidth requirements just to feed a single m3 core fully is 4bytes per instruction x 6 pipelines x 1800 mhz = 43 GB of bandwidth. Additional clock speed is useless if you can not get data into the cpu. It can't process data that it can't access. This is on top of fighting with the gpu for bandwidth.

There's a lot more to actual performance vs benchmark performance. Benchmarks can easily be swayed by using different data sets.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Doesn't matter. It was meant to run at a certain clockspeeds, and I've seen the analysis of the very respectable Andrei Frumusanu. Pushing the M3 cores to 2.3GHz in Quad Core mode yielded incredible performance increases. And funnily enough, that is the highest frequency before diminishing performance returns happen. In line with the clockspeed. Pair that with a RAM overclock, and this system will become a beast. The M3 cores had such a wide architecture it actually bested the stock Cortex A76. I don't test phones only with benchmarks, and I don't do "Real world" tests or "speed tests" either since they are extremely unreliable. I use the best and most objective benchmarks at hand (Geekbench 5, 3DMark, GFXBench and PCMark) and games the likes of Genshin Impact, Honkai Impact, Call of Duty Mobile, Battle Prime and Asphalt 9 just to mention some. Games are the perfect example of CPU and GPU having to work together, and this phone right now doesn't perform too hot in them due to the stupidly low thermal throttling point (70°C). Now I am not an architecture rat that knows every single detail of the transistors in the processor. But I do know that there is much more to this processor than Samsung unveiled. And rising clockspeed is one of the many steps to getting the true potential of this processor. Then comes what you mentioned. It's all of this together. It's not one or the other. This is how held back this processor was. And it's about time we wake it up.

https://xdaforums.com/t/kernel-andr...-n960f-v2-11c6-20210920.4294493/post-85591827
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
On the long term (have been using my phone with 2.11c6 now for nearly a month now) the Kernel is stable and the battery life feels like it is the same as stock (I use a performance-like status where CPU is constantly at max frequency and GPU is enabled, which SHOULD consume more power when the phone is being used, yet the battery life is just the same as stock, so there might be an efficiency improvement in this Kernel). Apart from some random fast-reboots when I enable mobile data, the experience is great. So yeah the testing for this release is complete now. Waiting for the next one.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
yeah i find the battery last a bit longer. before, when i surfed the net for an hour, it consumed around 15%. now when i used it for about 60 min, its about 10% and 13-15% for 90 min

some random fast reboots??
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Yeah they happen some times when I switch from Wi Fi to Mobile data while on plane mode. But that is not something that annoys me. What bugs me off is that as soon as the phone goes >70°C on CPU, small cores are FORCED to go at 1950MHz instead of the peak 2002MHz and I can't change it back to the peak frequency. You really have to rise the throttling frequency of the CPU once you are done working on system file improvements bro.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
you mean a phone reboot or just like a crash which restart from the boot animation? if the latter it should be rom related

yeah will take a look at that later. nevertheless it's 1950 vs 2002 only, and it wont last very long at that frequency, although i can understand your frustration
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
So it is not a crash because the phone does not do a full reboot (turns off and then shows Samsung Galaxy note 9 logo to then boot normally). It simply exits the operating system and goes back to the Samsung pulsing logo to then go in the operative system normally. App settings like HWtweaks ones are kept. It’s a fast reboot, on lineage OS it is literally an option.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Also it's obvious that 2002MHz on the little cores can't be sustained. The throttling happens as soon as the CPU temperature is >70°C. When stressed to 100% on both small and big cores, the CPU will reach 70°C within 10 seconds at a 24°C ambient temperature. Rising that throttling point at 90°C or 95°C if we want to go aggressive, would nearly eliminate throttling from the system running at 1794MHz on big cores and 2002MHz on small cores. That would yield performance improvements of around 9% CPU speaking (Big cores throttle at 1586MHz and small cores at 1950MHz at >70°C).

Also there is also the GPU problem. To give you an example

Me: Puts minimum GPU frequency at 572MHz

Also me: Opens a game

GPU: 260MHz

Me: :mad:

In fact the boost frequency doesn't seem to work. Even with the booster governor and with the boost frequency put at 15% usage, even when my GPU is over 50%, the frequency isn't the one the boost frequency one. It's always lower in games. I don't know why this happens but it hinders performance.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
I had it too, try to change Selinux to permissive.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I did so after your suggestion. Not sure what it should change though
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
we discussed your problem with one of s9 dev. He said "when selinux see there is root, it locks all the apps"

also I looked at the logs after the issue happened, logs say " system impiles root"

I think the issue is high possibly related with selinux state, if none works,

go back to Alexis 1.8 and BM R154 combination.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
But are you referring to the frequency issue or the fast reboot one? If it is for the latter, I really don’t care all that much. I don’t know what locking all the apps means since everything worked just fine with enforcing. Now I am on permissive. This is my main phone, I can’t just change ROM every 2 weeks lol. If the problem remains, I’ll stick with it. It’s not a dealbreaker issue.

Right now I am on Alexis ROM 3.0 and I don’t think I’ll change. I don’t want to miss out on the improvements the dev will make to this kernel either. It’s too much to lose for too little to gain.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
Yeah I mean the latter one. The problem you have experienced recently can damage to your cpu, because it gets to near 85 degrees. Also it is like a random reboot that can damage the rom files etc

If I were you, I wouldnt take that risk.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
can you explain in more details please? "when selinux see there is root, it locks all the apps". and how it affects the freq etc?

edit also i couldnt find any info about "system implies root". where did you find it? logcat?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
if you meant the gpu boost param found in most kernel manager, that means, eg

if you set min 299, usage = 15%, boost = 572

that would mean:

gpu min freq is 299. when the usage is 15%, boost it to 572 if possible

that's all.

i am not sure if this rule will remain active once triggered, since it depends on other settings etc. but if if is set to sustainable, then in theory it wont go down no matter what the situation is except cooling points come into effect, and it sounds not reasonable. isnt it?

so in your case it looks like you want to set it as min=572

previously when interactive governor was used, i supplied with something like below

if 15% go to 300, if 30% go to 450, if 50% go to 600, if 70% go to max
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
Yeah for once, I looked at logcat but it was deleted months ago.

Selinux realizes there is a security breach, and the breach is rooting the phone. After that Linux locks all the apps, no app is openable, and the phone heats wildly. I don't know why it is heating up.

I never see that issue after I put selinux to permissive. Also this heating up and locking thing never happens on ONE UI 2.1 roms such as Alexis 1.8, the problem only occurs on one UI 2.5 roms
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
Yeah that is correct. But I use the booster governor instead and the scaling just doesn't work bro. If I put at 15% load, use 572MHz, it just won't. It vibes at 260MHz at low usages. It doesn't go to 546-572 until usage is above 90%. Interactive Governor also seems to perform better than Booster, which is why I use it. But it still behaves super bad in games.

So yeah, what's reasonable for me is to set the minimum to 572MHz

too bad it doesn't work. Literally. It doesn't. It just goes back to 260MHz as soon as I get into a game. It totally ignores the rules and changes the value back to 260MHz on its own. It's a little bit annoying if you ask me. Actually it is very annoying lol. The cooling point also, is set at 71°C. It's very low, needs to be rised.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] TechNoobForSale:
I've seen in HkTweaks that my ROM has security features for file integrity enabled. So far I haven't had file loss either way. I am on permissive now though. Also 85°C is a high temperature for a mobile CPU but not a dangerous one. Dangerous is >95°C. Which is why I'd really appreciate having the throttling point of this kernel rised. It would yield great performance improvements and the phone wouldn't suffer any damage. Besides, those fast reboots didn't cause any high temperature issue in my phone.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
sounds like a bug though, it shouldnt block all apps in the first place
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] moderndaycowboy:
Yeah that is not clear still, idk what to say.

Now I am using Alexis 2.9 and BM v2.10 and I'd say, this is the best combination so far.

I set kernel to permissive and I never face any random freeze and afterward reboot.

Ps: was using Alexis 1.8 and Bm R154. This is the 2nd best combination I think.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ykkfive:
