And be more careful next time.
And be more careful next time.
so regarding the audio issue, i tried last kernel/app version and put the audio cpu value all the way up to 1700ish. Sometimes it works, sometimes it doesn't, but overall it seems better. I also noticed that sound gets distorted sometimes when adding too many effects, that might have to do with processing power as well? what happened to the idea of moving audio processing to the big cpu?
yesterday i posted a message on how to reproduce the issues, today i can't see it, not sure if it's some bug from xda...excuse me also for being slow and not following all the messages here, sometimes the xda app doesn't notify me of posts here.

@madhatter57
Did you reduce the little CPU Freq from stock value ? - Try to keep at 1690 MHz. Also check your little CPU suspend max_freq, try to keep 1690 MHz as well. And on Audio PM-QOS put 1690 MHz as well.
up_threshold value and boost on/off doesn't matter since we can set PM-QOS.
I use the original "Samsung Music" app and even if I enable all the sound improvements it still works fine with just 832 MHz. (tested with headphones, screen on/off)
Maybe you go over 0dB = distortion. Or little CPU is over 100% load.
Best way to check this is by using ADB while music is running over screen off with headphones.
e.g.
Code:
adb shell
su

...audioserver 73% with "UHQ Upscaler" + "Dolby Atmos"
PM-QOS 832 MHz = no scratching at all.
If I set 1690 MHz for PM-QOS i get only 46% load on audioserver:
Code:

That would work but it'll drain a lot of battery for just playing music lol.
Personally I play music with only "Tube Amp-Pro" and there is almost no load at all and works just fine without to force any higher CPU Freq for the little core. In fact it works fine with 455 MHz:

Hi guys. I've been using your kernel for about 1-2 months now, and now I've created an account on xda. Developer, can you help me, some games won't start for me. name: standoff 2
I think it's because of the RAM. I'm fine with my phone.

hi, sorry for posting it in the wrong place.
so, viper4android and jamesdsp use convolution technology for audio processing. jamesdsp just gives better/clearer results than viper, but something about that makes it use more processing power. as far as i understand it these use a lot more processing power also then the stuff that comes with samsung like uhq upscaler etc., and it was confirmed when i could finally get this adb code to read my phone activity (somehow my phone keeps disconnecting from my mac).
I could replicate the issue with sound scratching while watching audioserver load go all the way up to 90ish%. this was done with little cpu and audio cpu at @1794, which is the maximum i could get stable on my phone. but i did try before with @2002 and i could still get the glitches in sound processing.
when i use a more moderate approach to sound processing i cant get more conservative numbers around 50-60%.
what worked for me in another kernel i tested though, was to use performance governor for little cpu. though i could not push the audio processing too far, i could do more than i can now. i read that audio processing was moved to userspace governor, so i wonder if another change in that area would be interesting.
i understand moving audio processing to big cpu would be very battery intensive "just" to play music, but we are talking convolution processing of highres audio files. i guess it would be analog to playing heavy games like some of the guys here do
so i don't know, perhaps an option to toggle that on/off at user discretion? different governors or switch between big/little cpu to play audio?
i also understand that what i'm doing is very specific application of this trusted old phone so i understand if this is just going too far...
Standoff 2 can run on toasters. There has to be another reason.
idk. I have a black screen on startup. Try to run someone. I have many games and standoff 2 it runs on ultras. And on your core 0
Hmm I don't think it's any kernel issue. Also I doubt it's related to too low RAM. This kernel has the biggest amount of RAM for the S8 exynos series. So probably it's a bug with the game itself. Maybe Android 9 not fully compatible for that game. Or maybe not compatible with the ROM ? Have no idea what ever custom ROM you use and what ever mods you did on ROM side. Good luck.
@madhatter57
Alright, I'll see what I can do for next release. Thanks for your inputs.
Hi all, after playing with benchmarks on samsung dex and max cpu, gpu frequency (perfectly stable) I got these results. you made it like, you're the best. Thank you for your dedication and all the time you dedicated to the project. This is pink perfection!

I used 2 ROMs, it was a regular android 9 stock. And horizon ROM please help. It works for me with a regular kernel, but yours will be better
Hi @ace2nutzer
just wanna thank you for all your work (and active contributors of course) and let you know that i'm realllllllly late for joining the party, i started using your kernel since 20220624 version and right now i'm enjoying the 20220701 version in combine with the latest stock rom i had from OTA. Never really thought i would need root or even change the recovery/kernel coz the stock rom and kernel was already good as it is.
Originally, my motivation to jump aboard was the dex and drivedroid support.. but now i got the UV tuning madness coming back to me, still trying hard not to tweak performance settings til i'm sure my applications works without issue
there are 2 questions tho :
- drivedroid works but still can't figure out to working dex on my non-smart tv, is there a specific setting i need to switch before it could be activated?
- ANYBODY here use filmorago? mine used to work with no issue on stock kernel, but now it hangs on the splash screen but never enters ANR or crash. logcat shows nothing weird except for EGLint returns 0x3000 (tried clearing data, corpses/remnants, uninstall-installing, enabled all permissions for that darned app to no avail)
any solutions / recommendations appreciated.
TIA

For dex you need charger to active the dex i don't know that can happen with this maybe dev know where the issue is,
On stock kernel dex can active
Ok but don't expect that i'll fix that.
This phone is now old. Support and development is now lowered.
Also there will be no custom ROM from my side. Also I'll not add support for higher Android versions. But i'll try to keep this kernel alive by fixing critical bugs or critical security leaks. I'm working on a new Android app.
Also this is likely the last custom kernel / app project from me. If someone want to know why, just ask.

Nope, this is not how it should be done. You need Linux OS (e.g. Lubuntu) with installed "git" versioning system.
On GitHub create an new repository.
On the root of kernel source where u've the Makefile...
first of all, check if there is a (hidden) ".gitignore" file with following content: (if not, create it)
Then just open new terminal emulator and type: this: (I suggest to start from stock source code, then properly commit your changes)
NOTE: if your local git repo is already initialized, then skip the first 3 cmds. To check this, just type: "git log" if you see already some commits then it's already initialized.
Code:git init git add . git commit -am "initial commit" git remote add master https://github.com/opensourcefreak/KOLUMN_Kernel.git git push --set-upstream master master
Later if you do some changes, just commit them and push it to your git repo:
Code:git commit -am "CPU: added OC support" git push
With "git status" and "git diff", you can always check your changes before you commit them.
EDIT:
First of all, delete your Git repo, click on "Settings" then scroll down to the "Danger Zone".3
Yes but probably it's locked like all the other clocks it was. So it needs first some hacks like always. I remember on Ace 2 we OC'ed lcd_clk from 50 MHz up to 100 MHz. 100 MHz was sometimes unstable, but 80 MHz worked stable. Now that "50" is just LCD_CLK not refresh_rate. Also I don't know how it should be calculated ... 50 MHz = 60 hz and @ 100 Mhz = 120 Hz lol. Anyway at 80 MHz, probably around 100 Hz was it possible to scroll text without to cause eye cancer. Here on S8 there is also such LCD_CLK, but even increasing it, I don't see any difference, maybe I'll try this once again. There is also refresh value = 60, but even changing this @ 100, just changes nothing, so I suspect it's locked like I said.
Yes, that's right, because it gets out of sync. @ 80 or 100 hz it'll run probably smooth without the need to adapt other stuff in ROM, which is way more complicated.
Good idea, I'll see if I can do something.3OK guys I'm trying to make a new release that should fix high quality audio when using too much filters and slow screen orentation. Other than that I'm missing something else ?2

17FAQ
Q: With which ROMs this Kernel is 100 % Compatible ?
A: Currently only with Android 9 custom ROMs, but Samsung stock ROM is recommended.
Q: Is this Kernel 100 % Safe ?
A: Yes.
Q: Will this Kernel Overheat the Phone if I use Highest Settings ?
A: No, you can't do anything wrong. Your phone has hard- and software overheat protection.
Q: How to Revert all Changes Made by this Kernel ?
A: Flash latest 3-parted stock ROM with ODIN or flash the Samsung kernel from my download site.
Q: How to bypass SafetyNet ?
A: Anable MagiskHide in Magisk app.
Q: How i can Tune this Kernel ??
A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: How to get Max Speed for e.g. Highest FPS in Games ?
A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
Now you can even cook an egg on your phone !
Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
A: Yes, as long as you don't uninstall it.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Otherwise send me a pm with the screenshot and you current location (city)
Q: Why I get lower benchmark scores with this kernel compared with the Samsung kernel ?
A: This kernel uses by default Max CPU/GPU DVFS Temp 65 °C to reduce the device heat. You can buy the full version of the A2N app to set the DVFS Temp up to 100 °C to get higher scores than on stock kernel.
Q: Why the Android Battery setting "fast charging" has no effect on this kernel ? - It charges always with around 1500 mA.
A: Because it would conflict with the built-in charger control.
The default charging current of approx. 1500 mA means no fast charging by default, even if you actually see "fast charging" in the notification section. This is also useful to reduce battery stress and device heat. To charge even with higher speed/current than on stock kernel you need to buy the full version of the A2N app.
Q: Why I've to pay money for just changing kernel settings ?
A: Well quality has its price. Also nobody forces you to use this kernel.
You can flash other custom kernels or flash the Samsung stock kernel from my download site. Good luck !
Q: When we get an update ?
A: This kernel is almost 100 % stable and works very well. Also this phone is now a bit "old" and therefore don't expect frequent updates.
Also don't ask for ETA's and if you do anyway, I'll ignore.
Q: How to fix audio stutering ?
A: Increase the UHQ PM-QOS-LIT Freq in A2N app in "Audio" section.
If you don't have the full version, you can run a cmd like this:
Q: What is the benefit of editing the voltage table ?
A: to increase OC stability increase voltage and to decrease the device heat, decrease voltage. Last one will improve performance due to less throttling ! So it depends on your needs.
Q: How much is safe to undervolt ?
A: approx -50 or -75 mV is considered to be "safe".
Q: How to edit voltage table ?
A: First of all: to set different CPU/GPU clocks or voltages you need to have Magisk installed and buy my A2N kernel control app full version. This will unlock all premium features of this kernel.
To edit GPU voltages for steps > 572 MHz ---> use the A2N app full version.
To change all the other voltages, you need to use ADB and later once you have found the proper voltages for your phone then you can write them to a script that will be executed at every boot.
Note: this voltage table is from my phone. Your phone may have a different table, so please use your table when it comes to calculate how much you want to undervolt. (50 - 75 mV or 50000 - 75000 uV should be safe)
I'll help you, here we go !
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
