It would seem like it depends on how you use the device. I've actually only had one deadlock (ever) on my device. Have you tried comparing usage patterns with someone who does NOT get deadlocks?
[Galaxy S6 / S6 Edge Unified Development] arter97:
Which would be like finding a needle in a haystack.
[Galaxy S6 / S6 Edge Unified Development] MrWGT:
Maybe... But just for clarification: what is exactly a deadlock for you?

Device is not responding and you've to hard reset it? Or "just a extended hang" e.g. 2s and after that device is responding normal.

The second one i ger now and then but much better with b11 (less then 1 a week). The first with hard reset I've never had.

So for my side it would be perfect to release b12 just to test if b12 will work as good as b11.
[Galaxy S6 / S6 Edge Unified Development] arter97:
https://en.wikipedia.org/wiki/Deadlock

The deadlock issue on my kernel seems to be related to file-system read operation.

Something for some reason, is blocking read access to the file-system.

Apps and other processes try to access a file and, because something on the kernel is blocking its request, makes those accesses to wait indefinitely, forcing the users to reboot to recover.

Since some other low-end stuffs like core kernel threads are on the memory and has nothing to freshly access off the internal storage's file-system,

vibrations, inverting screen's color and other stuffs still remain working.

Deadlock is an (mostly)irrecoverable error,

whereas lags can go away in a few seconds.
[Galaxy S6 / S6 Edge Unified Development] cba1986:
i has to say that since i flashed via odin the latest official firmware for my device (EPE5 925i) using ext4. my phone hadnt experienced any single deadlock with beta11 (having using it for teo or three days without rebooting) and using bluetooth with my car stereo.
[Galaxy S6 / S6 Edge Unified Development] arter97:
Yeah I'm suspecting something is wrong with f2fs.

If anyone has this "deadlock" issue I described above(lags are not deadlocks!!) on ext4, please let me know.
[Galaxy S6 / S6 Edge Unified Development] turulojko:
Never had any deadlocks using beta11 from the first day on 920f and some day later on 925f on ext4.
[Galaxy S6 / S6 Edge Unified Development] MrWGT:
According to your clarification I never had a deadlock on stock DPDP with b11.
[Galaxy S6 / S6 Edge Unified Development] erghetto:
The fact that "android system" is always on first 3 position of battery statistics from what it could depend?

I'm just curious
[Galaxy S6 / S6 Edge Unified Development] Darktitor:
I'm using F2fs and no deadlocks ^^
[Galaxy S6 / S6 Edge Unified Development] jack allen:
hi i have had 2 of these deadlocks where iv had to enter download mode manually using button combo
[Galaxy S6 / S6 Edge Unified Development] nadejo:
That feature you portet from nexus android n. U called the kernels with mhz at its end
[Galaxy S6 / S6 Edge Unified Development] enotar:
Ext4 with b11 and no issues since release.
[Galaxy S6 / S6 Edge Unified Development] otymm:
F2fs on b11 and I get deadlocks several times a day
[Galaxy S6 / S6 Edge Unified Development] Murtaza110:
Currently, I have a rooted S6 Edge (G925W8 originally, but after the Xtrestolite ROM, it changed to G925F) running 6.0.1 with TWRP, so will this kernel work with Xtrestolite? If so, for which Model number should I download the kernel for? Thanks guys! (this can be flashed using TWRP too, right?)
[Galaxy S6 / S6 Edge Unified Development] Tim Niklas:
hey, your rom is based on the G925F Firmware. That's why there is G925f listed.

Your model will always be the same. So you should install a kernel For G925W8 but i think, arters kernel isn't comletely compatibel with your model.
[Galaxy S6 / S6 Edge Unified Development] VIVAS700:
Install the one for the G925W8
[Galaxy S6 / S6 Edge Unified Development] Murtaza110:
Oh, so Arter won't work as well (like the nice performance upgrade). Also, if I lose root, i just have to reflash the CF-Autoroot file I used when rooting my deivce to get root and SuperSU back, just making sure.
[Galaxy S6 / S6 Edge Unified Development] Tim Niklas:
maybe you should give it a try...

losing root will be very likely to happen. i would prefer installing the latest supersu beta (2.74) after flashing arters kernel.
[Galaxy S6 / S6 Edge Unified Development] Zinux:
It's okay.

Change your phone's model via build.prop

[Galaxy S6 / S6 Edge Unified Development] senzatiOn-:
[MENTION=4898097]arter97[/MENTION] mate why beta5 and beta-b have so more free RAM and why beta11 have small free ram ?

Just curiously.. more free ram beta5 but missing speed.. beta 11 missing more free RAM. :rolleyes:

I remember that u said you don't want to your kernel to be appreciated by RAM ... also some about unused RAM is wasted bla..blaa.. of much users.. ( i'm active user on your thread and read all new posts ) but I want to understand... because when RAM are more that 80 % phone get some lags.. visible on typing ... wach video, facebook scrolling and playing ( anytimes ).

Thanks.
[Galaxy S6 / S6 Edge Unified Development] Thijssie909:
I'm on beta 11 since day one and never had a deadlock...
[Galaxy S6 / S6 Edge Unified Development] arter97:
I was trying to see if loosening up swap usage can improve general performance, because I had a massive memory leak fixed.

While it did improve performance, it severely affected multitasking performance.

Don't worry, I made beta 13 with a bit more aggressive swap.
[Galaxy S6 / S6 Edge Unified Development] arter97:
Beta 13 is up.

I've reverted some hotplugging CPU commits,

made swap more aggressive,

re-enabled cpuset feature,

applied some f2fs bug fix commits,

and added T-Mobile and W8 variant support :)

Please feedback on deadlock,

and tell me if you're on f2fs or ext4.

I'm fairly certain that I've reverted every possible culprits of this deadlock issue except for the hz_test's 300 Hz tick clock change.

If deadlock is still present, I'll be reverting tick clock back to 100 Hz.

[Galaxy S6 / S6 Edge Unified Development] *ReZa*:
and yes, same here, for me beta 11 is awesome release, no deadlock at all, amazing performance that i never saw befor, just a small problem which is a little bit annoying and thats overheating while you play games, i cant play clash of clans more than half of hour while we are entering the summer and the surronding tempreutre in 20 25 C. the phone really becomes a heater, maybe this heat is the cost of great performance, but i really hope it becomes fixed in next release, thnaks arter
[Galaxy S6 / S6 Edge Unified Development] senzatiOn-:
Amazing... first impresion.
[Galaxy S6 / S6 Edge Unified Development] faisalis10:
I lost root when i flashed tgis kernel which suoer su version should i flash back?
[Galaxy S6 / S6 Edge Unified Development] nadejo:
That tick clock i ment with 300mhz. Im sure its the cause but maybe some other tick clock frequencies are stable.
[Galaxy S6 / S6 Edge Unified Development] mdcool:
Installed beta 13 over beta 11 with no wipes 30 mins ago. 2 observations so far:

1) a lot more free ram. 600+MB, sometimes up to 0.9 GB

2) phone lags. Seems like BIG cores don't scale, even when updating software from Google Play (e.g. that monstrous Facebook app) they tend to stay at 800 MHz. Reboot didn't help, other apps were installing slowly. Launched Chrome with 60+ tabs on idle cold phone, started walking through tabs to load them: little cores jumped to 1500, BIG stayed at 800.
[Galaxy S6 / S6 Edge Unified Development] mdcool:
30 mins later:

I let the phone cool down a little bit and finish all background tasks. Now it's snappier. BIG cores started to scale (according to Kernel Adiutor Frequency table). Seems like it was DVFS, however phone was not this hot to cut down performance this much.
[Galaxy S6 / S6 Edge Unified Development] senzatiOn-:
Flash supersu and after reboot install supersu from playmarket.

[Galaxy S6 / S6 Edge Unified Development] Evo17:
Thanks after for adding w8 variant support! I used this kernel back with lollipop and was dying to try it for marshmallow. Only thing is the call audio does not work, will the lollipop audio fix file work on this kernel?

Just tried the "marshmallow audio fix" and it does not work.
[Galaxy S6 / S6 Edge Unified Development] arter97:
That will be ROM related, not the kernel.
[Galaxy S6 / S6 Edge Unified Development] Evo17:
Understood, thanks boss!
[Galaxy S6 / S6 Edge Unified Development] virulentt:
Thanks arter for the support for W8! <3
[Galaxy S6 / S6 Edge Unified Development] desfirenze:
beta 13 is great for me, myphone not overheat or hot again, thanks arter
[Galaxy S6 / S6 Edge Unified Development] s89281b:
What rom are you running? I just flashed 14b13 on 920t running xtrestolite 3.3.1 ext4 and call audio works perfectly.

So far everything running very smooth. all apps opening instantly. video playback starts much faster. games are smooth.
[Galaxy S6 / S6 Edge Unified Development] Evo17:
I'm on the same rom! Thats odd, I reflashed boot.img back to stock 3.3.1 I'll give it another go I guess.

Edit:

Still a no-go :(
[Galaxy S6 / S6 Edge Unified Development] Harregukalerik:
somethings wrong.....or have I done something?
[Galaxy S6 / S6 Edge Unified Development] arter97:
1. Remove Synapse app

2. Remove /data/.arter97 directory (it's hidden, use root explorer or something)

3. Reboot

4. Install Synapse
[Galaxy S6 / S6 Edge Unified Development] evonc:
Can confirm no call audio as well with stock and b13 tested with identical rom. The call connect tone plays on b13 but no audio afterwards in earpiece/speaker. Reverted back to stock kernel without changing rom and in-call audio is working properly. This is on 925W8. I'm not sure if the issue is same for 920W8.
[Galaxy S6 / S6 Edge Unified Development] arter97:
G925T/W8 issue is confirmed.

I durped the kernel config.

G920T/W8 should work fine.

Fix will be merged for b14.
[Galaxy S6 / S6 Edge Unified Development] s89281b:
I am assuming call audio was working for you before flashing kernel? any other mods? I had a clean install of 3.3.1. no other mods installed. only thing i had to do was reflash su. but call audio was working for me before and after flashing su. Are you using kernel with soundcontrol or without? I flashed kernel listed as G920TW8. You have double checked that you got correct file?

Edit: Arter97 already found problem.
[Galaxy S6 / S6 Edge Unified Development] Harregukalerik:
Thnx that worked:good:
[Galaxy S6 / S6 Edge Unified Development] arter97:
Beta 14 is up.

http://arter97.com/browse/exynos7420/kernel/beta/14.0-beta14

Fixes G925T/W8 issue, and binder(which plays a key role in Android UI performance, smoothness, etc) has been revamped.

This is obviously not tested much, but I'd like users to test it with me :)

how do i connert to f2fs please buddy
[Galaxy S6 / S6 Edge Unified Development] space_eyes:
Ty so much arter97 !!
[Galaxy S6 / S6 Edge Unified Development] Paz9:
can i restore a backup after converting to f2fs?

also is there a changelog to the b14?

i used hacker kernel for abit but i keep coming back to arter97, arter is more superior in every aspect except 1. customization.

i know its the devs option to add or remove certain customizations but it would be nice to be able to UC our GPU or limit the freq used or voltage to help save power better.

i know that there area already bus voltage controllers in synapse. but i notice a lot of battery saved while limiting the gpu freq on the hacker kernel.

i can only imagine how good itll be on the arter kernel :)
[Galaxy S6 / S6 Edge Unified Development] Maiaman:
The kernel is fantastic, just fantastic.

My "S6.5arter" rom stock G920IDVS3EPE2_G920IUUB3EPD2 Without any modification, hundreds apps + games + all Bloatware. (Facebook, Microsoft, Google, Samsung). No f2fs, on "move invisible apps to A53".

Thanks grand dev arter. Thanks

* be obvious, Battery and any instability ñ it is possible to report now.

Donations symbolically is for recognition and admiration.

I will continue to make independent.

watch your own business i wasn't talking to you ?
[Galaxy S6 / S6 Edge Unified Development] arter97:
A. Disabling swap on Touchwiz will :

severely reduce multitasking capabilities, killing apps repetitively on the background, causes services to respawn frequently

->

performance decreases and power consumption goes up.

Don't do it.

B. 0 VFS cache pressure is nuts. Leave it as the default.

If I press on the top left side of the screen, it registers on the top right side.

Installed b14 yesterday morning and today I had my first random reboot and deadlock ever. :crying:

After the random reboot I logged into my phone (920F) by entering my passphrase, unlocked my Threema and opened up tapatalk to have a look at the forums. Right after opening the arter-kernel-thread the phone got stuck and I manually had to reboot it as nothing but the colorchanger (quadpress) worked anymore...

Never had any issue like this before on my phone with any arter kernel (using the kerne since 13.1 and did almost every update released) with xtstro rom.

Anything I can contribute to get a clue what happened ?

Thnx

SOT for watching videos or doing stuff and so ?

The case has an 3.7 V battery.. 4000 mAh.. If you calculate this: 3,7 V * 4 A = 14,8 Wh.. 14,8 Wh / 5 V or QC 2.0/Fast Charge (9V) I don't think this case support QC 2. 0 or Fast charge.. Pretty useless without it. So for normal output you get about 2.96 A minus capacity that is still left in the case, so the Lipo doesn't get damaged.. So you can exept 2,5 A output ±0,2 A..

So "real" SOT for me is about 2-3:30 hours.. How do you got 13 Hours ? Screenshots ?
