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.
I did so after your suggestion. Not sure what it should change though
we discussed your problem with one of s9 dev. He said "when selinux see there is root, it locks all the apps"
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.
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
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:
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.
Yeah for once, I looked at logcat but it was deleted months ago.
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.
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.
Yeah that is not clear still, idk what to say.
I would really appreciate it if you can. The benchmarks results for the current version of the Kernels you know already, since I do them frequently to study the performance differences between each release. I'll tell you how much the higher throttling point will benefit performance. Also to be honest it shouldn't even be that hard. At least as far as Snapdragon is concerned. Because on Snapdragon devices there is a simple file regulating the way throttling works. It's called Thermal Engine or something, and it can literally be edited while you are in OS. I don't know if Samsung made things more complicated for Exynos though. It should still be a bunch of variables though.
) ). Thanks!u mean 2.04m?
i have did some tests today and yes, 2.02 is the fastest one, it was the original one without any "enhancements" in other aspects like cpu/gpu overclocking. it is not unusual that these enchancements can be beaten by the one without in terms of performance. it all depends on the usage, and more importantly everthing comes with a price. so you may find it at stock max speed outperforms an overclocked cpu due to the heat generated (which trigger the mechanism to lower the cpu freq as to cool it down). eg a 10 seconds task running with 2000Mhz may be better than 3 seconds with 2400mHz plus 7 seconds with 1700Mhz. you see what i mean? of coz, once again, it depends on the usage and the way of using it like benchmarking or daily use
