I used solid explorer and also tried root explorer. Everything in the /debug folder is empty (0Bytes), but not in the /kernel folder. In the TWRP filemanager the /debug folder is empty (no folders or files)

Copy the file you want to read somewhere else, then open the copy. File viewers don't always understand files that get generated on the fly.
[Galaxy S6 / S6 Edge Unified Development] ricardofago:
Solid Explorer won't be able to read the file, even if you copy it somewhere. Best way in I know is to download Termux or Terminal Emulator and sudo cat /sys/kernel/debug/asv_summary. It will ask for SU permissions and then print the contents of the file in the console.

Hello [MENTION=4898097]arter97[/MENTION] I found the cause of battery drain of android system, it's excesive when wifi is on, I was with it off 12h ago, and its not so high, if you can take a look at that, it would be great, thanks in advance.

There is no connection with this kernel. Android system high consumption appears in stock versions and want the truth then use another tool. The BatterbatteryStats app is a good choice but is not friendly for beginners. there are other issues but do not speaking Ingles for a bit. Sorry about
[Galaxy S6 / S6 Edge Unified Development] Taranis01:
Thanks for the help. I am not able to do it.

Also sudo command wasn't found. I tried su instead, but even the terminal asked and got for root i got an error (permissions denied)

[Galaxy S6 / S6 Edge Unified Development] sofir786:
Tbf even on hackers kernel I had android system process as 2nd highest process.
[Galaxy S6 / S6 Edge Unified Development] ricardofago:
My bad, sudo doesn't work. Type su first, grant permission, then type cat /sys/kernel/debug/asv_summary. If you get permission denied then you aren't superuser (check the user on the console), maybe you took too long to answer the request. Erase the Termux entry on SuperSU app and try again.

Bro, its a general android bug. It has nothing to do with this kernel.

This a stock, unrooted Galaxy S7 screenshot
[Galaxy S6 / S6 Edge Unified Development] erghetto:
I don't care of what happens on different phone. I am only saying my experience with this kernel and stock one.

That's all.

However i am not underlining this thing to criticize, i am only curious to understand why, right after flashing this kernel, that android system starts to be up in battery usage.

On every stock kernel i have tried, i have never had this problem.

[Galaxy S6 / S6 Edge Unified Development] Maiaman:
Thanks for sharing your hobby "work" with us, I am using f2fs now and is not placebo, my device looks new super model. Without demagogy but you're the guy is very talented brother genius his work is very different!

Using your kernel from the first version. That's what brought me more satisfaction since I bought my S6. I suffered enough to get f2fs using TWRP with philz touch was much easier. I am using latest version stock s6 920i.

???????
[Galaxy S6 / S6 Edge Unified Development] erghetto:
In busses i see 3 section in synapse. Which one can be undervolted?

Oh, and if you can, could you upload screen of your voltage?

I know it is different from phone to phone, but it is just to have an idea.

P.s. when you say "Undervolt ONLY A57 for 100mV for beginning", do you mean every frequencies of A57 of 100mV?
[Galaxy S6 / S6 Edge Unified Development] DevisG79:
[MENTION=4898097]arter97[/MENTION] Until when will you support this kernel?

What about future Updates and security patch Level for this device? Is it worth rooting and flahing this kernel because you will leave us. I appraciate your great work.

That's very sad.
[Galaxy S6 / S6 Edge Unified Development] observingi:
What's the purpose of HPM voltage? Once set to 0, do we have to revert to original value after finding the undervolt sweet spot?

Thanks
[Galaxy S6 / S6 Edge Unified Development] erghetto:
Me too wnated to understand and googling i found this.

Taken in vindicator thread, said by [MENTION=4517211]Xileforce[/MENTION]

"The voltage margin is for the apm which is a sort of dynamic voltage controlling processor created by Samsung. My understanding is that the apm will dynamically reduce and increase voltage as needed. This is completely separate from the normal voltage controls. It applies on top of them."

Edit: so Aria.97 set it to 0, so that the undervolting done, are the ones kernel follows, without being influenced by this HPM
[Galaxy S6 / S6 Edge Unified Development] Aria.A97:
1. You can undervolt everyone.

2. That's Pointless. I know someone else will apply that and run into instability. Then we'll see another 5 pages of annoying off topic. I'll send a pm to you.

3. Yes every frequency.

Well I couldn't find enough info online and this is my guess. HPM will undervolt frequencies based on utilization. Example :

If you undervolted 800 Mhz to 600 mV and HPM is 25 mV, when device is idle it'll undervolt even more down to 575. When I was undervolting my phone would shutdown in deep sleep. Decreasing HPM to 0 solved my issues. Well this was how I undrvolted, you can leave it as it is if you don't face any problems.

[Galaxy S6 / S6 Edge Unified Development] sofir786:
Personally for me not worth it, the rom I run has viper audio which has more than enough control options to tweak audio to my liking. So depends really the rom you are running but anyhoo that's just my choice.

[Galaxy S6 / S6 Edge Unified Development] drnjstj:
[MENTION=4898097]arter97[/MENTION]. Thanks for the final build. Feels better then beta 1 no slowdowns. Thank you for that!

I did a dirty flash of the final build. Now some of my messages (WhatsApp) are delayed. Is this due to the dirty flash or do others experience the same.
[Galaxy S6 / S6 Edge Unified Development] feelpt:
You using any bat saving app like force doze or amplify? I noticed same behaviour sometime ago and found out it was those apps that were delaying the system in those situations... still dont know exactly which one it was, but doesnt seem to be kernel related
[Galaxy S6 / S6 Edge Unified Development] drnjstj:
Thanks for the reply.

No I don't use any and I didn't change anything compared to b1. So you don't have the issue and you did a clean install?
[Galaxy S6 / S6 Edge Unified Development] feelpt:
Not sure you can consider clean install... i had xtrolite and stock kernel running for a couple of days, and then i flashed arter.

I noticed that those issues stopped when i uninstalled those apps i mentioned (still while i was using stock kernel).

Since i flashed arter i didnt notice the issues happening again. Can you specify what triggers them or how do you notice them? Maybe i could try to see if theyre still here
[Galaxy S6 / S6 Edge Unified Development] drnjstj:
I used beta 1 and didn't have the issue. Didn't change anything, only installed the final version, but dirty flashed it. So it could be the dirty flash or the final version.

I wait a bit and see if others have the same issue. Otherwise I'll try the clean install.
[Galaxy S6 / S6 Edge Unified Development] Ognjen123:
I just flashed the kernel didn't change nothing else. Wiped cache and Davic before and after and that's it. I just took the phone if charger and same second battery went from 100 to 97 %...

Random reboot here
[Galaxy S6 / S6 Edge Unified Development] dupel:
Can't seem to find the answer. Will converting to f2fs format (as in erase all data) the partition?

So, if I convert data and system, will I be able to boot and have all my files, or I need to back everything to PC, convert, install rom and transfer files back? Thanks in advance for answer!
[Galaxy S6 / S6 Edge Unified Development] Rebel25:
If you convert to f2fs you will need to backup your data and then copy it back to your device.
[Galaxy S6 / S6 Edge Unified Development] foeti:
Had a random reboot too.... maybe I can get last_kmsg next time.

Also have a question: every now and then my capacitive buttons get weird for some minutes. They light up and become self-employed.... can't use any app for 2-3 minutes cause back button directly quits every action....

Dunno if it's rom or kernel related. Had this even in the previous versions.

Do you guys have any suggestions?

[Galaxy S6 / S6 Edge Unified Development] dev-host.eu:
Make sure your rom developer supports F2FS.
[Galaxy S6 / S6 Edge Unified Development] thecrab93:
For the people that can't seem to get f2fs working because the ROM script formats back to ext4, it's been said before, but basically what you want to do do is install all the the zips that you need, then make a backup with twrp, format the partitions that you want to convert to f2fs and restore your backup, if I'm not mistaken that should work.

---------- Post added at 02:23 PM ---------- Previous post was at 02:20 PM ----------

Also, always remember that when you convert/format any of the partitions you'll lose anything contained in them, so if you convert data partition you'll lose all you files (photos/music/etc)

Test kernel for G925T/W8.

G925T/W8 variant is the one that lacks proper open-source from Samsung.

Some dtb entries are missing, so testing is necessary.

If someone has G925T or G925W8, please test the linked 3.0 kernel.

i just don't know if i need to (and i can) convert system and cache to f2fs... because at this point only data sticks to f2fs, the rest is changed to ext4 after flashing rom.

at some point i also read that maybe it was needed to convert rom to f2fs, but if rom supports f2fs i don't need to convert rom, right?

thanks in advance
[Galaxy S6 / S6 Edge Unified Development] thecrab93:
Also what dev-host.eu said is also true for system partition, so if your aren't sure the ROM supports it just convert data and cache, you won't lose much for not converting system as that's not a partition you're writing to all the time hehe

To convert go to twrp, click on wipe, advanced wipe, then tick the partition you want to convert, and click on repair/convert button then select f2fs, you can only do one at a time, and remember you will lose everything in that partition
[Galaxy S6 / S6 Edge Unified Development] ElementRn:
You have to boot into TWRP. Tap on wipe advanced wipe format the partition you want to change to f2fs. Afterwards you go to wipe tap repair or change file system and select f2fs. Once your done you restore the backup. Saving the backup on an external storage like a pc is recommended.
