Hey. Can I ask what is so wrong with f2fs and art? I know you tell that multitasking is worse on art but for me overall smothness on cm 11.18 and kernel 04.25 seems to be better. And one more question - can i manually add libart.so to cm and it will work? The same question for f2fs.
[Galaxy Ace II Android Development] ace2nutzer:
ART:

- Experimental and no support from Cyanogenmod Team.

- Eats for me 500MB on /data

- Bad Ram Management

- Many Apps doesn't work properly i.e. Maps FC after every boot ...

- Doesn't make the Phone faster / not more Points on Antutu.

- Takes too long time to boot after wipe ART-Cache ...

F2FS:

- Experimental

- Buggy

- Not very consistency like Ext4

- To often Filesystem corruptions

- eats over 200MB on Cache and System

- Also not more Points on benchmarks ... even less Points...

In Totally it makes a wasting of useful/precious 700MB of space on our NAND-flash for Zero Benefit :highfive:

So absolutely no more Support for Buggy/Experimental features :o

Next Builds will have more improvements .. always the same.. just always trying/optimizing for more speed, more smoothness and better battery lifetime ... that's what a great kernel should do :cool:

[MENTION=5840412]ace2nutzer[/MENTION]

I did not see in the changelog of your ROM on the google service FC fix. Is it not included?

Anyway, just flashed it, and it does feels smoother, great job. :D
[Galaxy Ace II Android Development] Arf29:
It's very good, but for me battry draining too fast :(
[Galaxy Ace II Android Development] shaqman89:
Have you tried to use power save in cm performance profile?
[Galaxy Ace II Android Development] Arf29:
yes, I've tried but same in power consumption
[Galaxy Ace II Android Development] NeosHaruki:
Yes I know but it still didn't work

Thank you for developping the kernel of ACE 2 GALAXY . i just installed it on " KK AOSB v 1.3.7 "with KK Mini gapps .

i got only one Gov : Dynamic . and batterie is draining very fast while using 3g connexion .

AOSB v 1.3.7 is until now the best . just try it
[Galaxy Ace II Android Development] Jaro89:
Ok, probably you're right, you have experience as developer. But in my observations f2fs gives boost to IO operations and supports autotrim (very important, cause ace II have extremely slow flash memory). After changing vm to art, in other hand, in my feeling, apps runs faster and ui is smoother. I will convert filesystem to ext4 and after few months will judge by myself how it will perform. And i will add art libraty by myself. Anyway, thanks for everything you do for ace II, you are great :)
[Galaxy Ace II Android Development] ace2nutzer:
Nope, it's just based on 05/05 of Chronos CM11 .. to fix that Bug recompiling is needed ... but u can use the temp fix posted by fluffi444 on Rox's CM11 Thread ... i hope Google will fix / update soon their Google Play Services..

It's calibrated only for the CM11 from here ... there is no guarantee that it works as well like my CM11 here...

Try to check if CPU Freq can stay @ 200Mhz on IDLE .. just go to Settings ---> Performance ----> CPU ....

Remove also "set on boot" ... maybe wrong min/max CPU freq ...

Try also to use 2G + Wifi ... ( 3G + Mobile Data was never great for powersaving... especially if signal is bad )

Use CM Performance Profiles...

It's already at minimum possible ... CPU/GPU Min 200Mhz ... and Undervolted ... If i set something lower it'll lagg ...

Usually for that smoothness it was needed CPU/GPU Min 400Mhz in the past with interactive Gov ... but now with the new CM11 + Dynamic Gov.. + many Kernel optimizations makes it possible to reduce the Min freqs to the half !
[Galaxy Ace II Android Development] ace2nutzer:
If u like anyway to destroy your Ram Management, then add back ART like this: Add the 2 libart ....so to /system/lib and also one artcore.jar (or smthg like that) to /system/framework ... get this files from 05/05 CM11 ...

But then pls don't report Bugs ;)
[Galaxy Ace II Android Development] Matteo90:
Thanks [MENTION=5840412]ace2nutzer[/MENTION] for the hard work! :good: :)

I flashed the new kernel on your 1118 rom (until this google play services thing is sorted out with the new), and while antutu gives around 2k less points, real world performance seems to have improved. But I get more black screens than before and also call screen takes a couple of seconds to appear. Could it be because of 200mhz instead of 400?
[Galaxy Ace II Android Development] ace2nutzer:
Hmm i don't have less 2k points with the actually CM11 based on Chronos one ...

I hope u don't let run the Antutu Bench while Google Play Service is crashing ?!! (if yes really no wonder)

I suggest to use anyway the latest CM11 ... Fix that Bug with that Fix:

http://xdaforums.com/showpost.php?p=61034998&postcount=230

Hmm if it take too long time by appearing the call screen.. then it's related to the suspend_max_freq .. it's set to 400Mhz .. maybe to low... u can try to increase at 600Mhz .. that should be enough... take a look into the Dynamic gov. Folder and do echos ...

As for Blackscreen: check actually LCD freq ... and then try to reduce it with the available init.d script: 01_lcd_clk

If u've 36Mhz... (s6d) try with 33Mhz ... if it also didn't help.. try 31Mhz ... (this is the org. freq... but probably mostly laggy)
[Galaxy Ace II Android Development] Matteo90:
Sorry for being a noob, but could you tell me how to do that? :) I found the folder, but file manager fails to edit the file...
[Galaxy Ace II Android Development] ace2nutzer:
as i said .. u need to do echos:

echo 600000 > /sys/devices/system/cpu/cpufreq/dynamic/suspend_max_freq

Put this line in one init.d script at the bottom.. save and reboot.

If it doesn't help, then remove this line again ....

Right now tested: for me Call screen appears max. after 2 secs. the Phone is belling ... (with suspend_max_freq 400Mhz)
[Galaxy Ace II Android Development] Alex_Gamer:
Bro.. I just wanna say that you do a masterpiece of development on that device, is not an s4 mini and don't have 1gb of ram but using your kernel and rom is flawless, my most sincerely grateful to you you're a boss just keep it up dude :)
[Galaxy Ace II Android Development] Jaro89:
Yeah, I already did that. For me ram managament is not that bad and i prefer more smooth ui. As for google services - i always block it from updating. I'm using v 5.2 and little older versions of youtube, gmail and maps. Thanks to that i don't have problems with fc's, battery draining etc. And i have more free ram.

Everyone can freeze updates of gapps version he likes. If you don't know how, i can tell.

if u're on my 18/11 CM11 with latest Kernel here.. can u pls check if BLN Settings are still available on Settings ---> Profiles ??

Thanks ... (I can't find it anymore.. or i'm forget where to find it)
[Galaxy Ace II Android Development] ChronoMonochrome:
Just got the idea in my head - isn't ART is so worst in this ROM because it's not supported by CM? They even simply haven't merged fix that allow device to boot up with ART(so developers has to do it manually). Anyways, gonna try to compile another kitkat ROM (yes, I think we are still missing fully bugfree kitkat ROM).

Our implementation is quite old, so probably there's no need to wonder, why it doesn't work properly. I previously PMed you that nobody willing to port more less recent F2FS implementation for our outdated LK 3.0, but apparently I was wrong, XperiaSTE team made backport recently - https://github.com/XperiaSTE/android_kernel_sony_u8500/compare/3258ff92c0...e2c2c91273

I haven't tested it yet, because it doesn't work on my kernel properly (my backport of writeback from recent LK messes this F2FS implementation up) - will test it later, because there are many things I will need redo to make it work :)
[Galaxy Ace II Android Development] Matteo90:
Well I don't use BLN, and after a quick look in settings, I couldn't find anything BLN related either, only backlight in buttons menu.

But shouldn't BLN settings be in NT app anyways??
[Galaxy Ace II Android Development] ace2nutzer:
I believe ART will never work properly on kitkat .. but try your luck! ;)

I didn't test it yet, but maybe on lollipop it'll work properly ? Since ART is official created for lollipop and not for kitkat ...

@ F2FS .. that's a good idea.. i'll look into it soon :) Thank u !

Thanks for looking into it ! But did u check ---> Settings ---> Profiles ?? if there is something with Backlight ... just tap of one default profile ... let say "standard" ... and check pls .. thx !

No... u can enable the BLN in NT-APP that's right .. but it has nothing to do with the Settings in Profiles ... it's missing .. so it can't blink .. even if BLN is enabled correctly .. in NT-APP. There is smthg messed up... i'll also check what's the cause of that by installing old 18/11 and/or also older kernel ...

I need to clear something up: what are defaults of gpu for ace2(gpu clock, that is)? Is this one-state, or lo/hi state..
[Galaxy Ace II Android Development] ace2nutzer:
on Stock JB Kernel:

400Mhz

on IDLE: 200Mhz (CPU 200Mhz)

Screen ON but no movings things .. (example watching a Photo, without touching the screen) ---> 0Mhz

On this Kernel:

200/400Mhz (Profile Balanced incl. MaliAutoBoost)

on IDLE: 100Mhz (CPU 200-400Mhz)

Screen ON but no movings things .. (example watching a Photo, without touching the screen) ---> 0Mhz

It was my mistake I was using a newer version of ogyoutube!Do you have any issues with google play crashes?? Any solution?
[Galaxy Ace II Android Development] ace2nutzer:
Nope.... i did just one time clear cache folder of G.P.S. + removing write permissions ... and till now, no one FC for me :)
[Galaxy Ace II Android Development] Matteo90:
I checked profiles as well, but nothing of interest... :/ I can post screenshots if you wish, though.
[Galaxy Ace II Android Development] gepel:
Sad to say but this rom is complete useles in case that you want to use iit with a gps program like navigon. After a few seconds google play services crashed, and after that you have uninstall play services and rebootin order to use location again.. Any idea or fix for this , or i have go back in my old config ?
[Galaxy Ace II Android Development] forza-Juve:
have unchecked "start on boot for performances und reinstalled kernel . still always showing one performance profile on CM11 Performances profiles. on Idle have 800 MHz .

A graphic issue with cm11 :

Black artifacts when zooming on Google earth .

thanky you
[Galaxy Ace II Android Development] ace2nutzer:
@ up

uncheck everything on Performance ... then reboot the phone ..

then u should see (in cpu gov. section) min 200 max 800 .. and actually freq should be 200Mhz (wait 3 - 5 minutes till system is completely booted) .. if not there is a problem with one user app that cause too much CPU load ... the CPU freq can only stay @ 200Mhz when CPU load is very low and of course when all apps are good.. there are some mis-configured apps on Play-Store that cause too much CPU load .. even when the app is running on background as cache ... try to find what cause it by typing "top" on term. emu.

What are u meaning with only one performance menu ? There is only one gov. available dynamic.. but u've 3 performance profiles: Powersave, balanced, more performance i suggest to add the CM performance profiles to the Quick Settings .. then u can switch the profiles with a single tap ... and at the same time changing this way CPU / GPU Freq with one tap ;)

@ all

U can expected soon new kernel update with some improvements and including a fix for BLN + Google Play Services temp Fix.

[MENTION=5535372]Matteo90[/MENTION] Many Thanks for looking into it .. u're right.. there is no BLN option in Profile section ... because of simply missing in the ROM .. so it can't never blink.. even when the Kernel is perfect and when BLN is activate correctly...

Right now i've found out that the latest working CM11 Version with BLN is just Build by TC 20141003 .. i'll try to extract the missing Menu for BLN and put this file(s) in next kernel release.. then it's auto. applied in our latest CM11 here :cool: :good:
[Galaxy Ace II Android Development] gepel:
About the problem with the google play services , i believe that its not related with the kernel. Now Im back on 1811 rom with the latest kernel and everything seems to work properly. Anyway im going to continue the testing and i;ll inform you for the results.

UPDATE; Almost a day of full usage (gps guide included) and i dint faced the problem with google play services with the above set(18/11 rom + latest kernel)
[Galaxy Ace II Android Development] forza-Juve:

i installed your cm11 and kernel . Profiles are shown , trying balanced everything work good . Great Thing your Arbeit .

Danke

und Respekt
[Galaxy Ace II Android Development] frittentheke:
It seems to be related to the Google Location services. I disabled the "accurate" or "high precision" location using Google and forced the phone to use GPS only. Now the crashes seem to be gone (and so is the quick determination of my own location :( using Google ).

ace2nutzer said something about a temporary fix

So maybe he already has an idea what the issue is.

Currently, my Ace 2 is running with: codina_kernel_cm11_20150422_ext4_ace2nutzer & CM11-20141118-UNOFFICIAL-codina

What I would like to have: cm-11-20150526-UNOFFICIAL-codina

Is it possible to install it without making a complete new installation including reinstalling all apps?

If yes, what are the steps I have to do?

Thank you for your great work! :)
[Galaxy Ace II Android Development] shaqman89:
Yes, just flash it directly like you normally do. No need to do a wipe cache and especially not data.

Do make a backup, just in case something goes wrong.
[Galaxy Ace II Android Development] ace2nutzer:
Yeah it has nothing to do with kernel... but i can include fixes for a buggy ROM in kernel package.. that's it !

On 18/11 CM11 ROM there is no issue with the Google Play Services .. because that ROM was compiled with GCC 4.8 .. (seee Rox's Changelogs.. ;) ) And the new CM11 here based on Chronos latest CM11 is compiled with the newer/better GCC 4.9 .. and the Google Play Services aren't actually compatible with GCC 4.9 compiled ROM ... but i say it again:

It's really not need to use just for only one (small) problem an outdated ROM ... we can Fix the Problem by simply deleting GooglePlayServices Cache Folder + removing write permissions .. and u can use the Phone normally without any restrictions ! The latest CM11 have many Optimizations like this Kernel here... for example: Just Archi optimizations ... and so on ....

For me i can really say: the new CM11 is working with "balanced" Profile, nearly so fast like OC'ed 18/11 ROM .. !

For those they don't want to wait till i'll release next Update... Fix the G.P.S. FC by yourself:

1. Open FileManager

2. go to /data/data/com.google.android.gms and remove write permissions for "cache" folder like on screenshot.

3. Go into "cache" folder and delete all files ...

4. u're done.. FC will no more start again :)

Hi,

thx for freshest rom and kernel ace2nutzer

but I have a problem with google play services , namely pops up from time to time notification of unexpected shutdowns .

besides , I found a few bugs , namely both in folders system / app

and system / priv -app several applications with the extension .bak ,

for example cLock.bak and VoiceDialer.bak

any suggestion??

oh and one more thing .... I bought the pro version nova launcher, but I can not use it until when I delete launcher from ROM and install it again
[Galaxy Ace II Android Development] shaqman89:
It's a known issue, just disable GPS, or use fluffi444 fix (sorry no links yet)

It's not a bug, those bak extension means that the application is frozen.

I think this may be caused by the ROM already includes nova launcher by default.

What do u mean with "changes" ?

CM sources from 20141003 ...

Camera fix from build: 20141118

Contacts FC Fix: from 1118

Live Video + YT Fix from Chronos 20150505

I've first wasted the whole day to make it "all" working with CM Sources from Chronos 05/05 .. but at the end the System UI incl. Lockscreen was completely messed up.. :(

Just for info: in this CM11 from me , there is no more need to use the temp_fix for Google_play_services :o

@ all

I've re-uploaded older gapps package .. i did it messed up by manually including latest Playstore + Google.Play.Services in the package... that was a bad idea... so that new upload is org. package made by TKruzze

Just flash the gapps 20150308 and the problem is fixed !

Download:

http://d-h.st/hrsq

But if u'll face gapps FC after boot ... then reboot to recovery and mount /data over cwm .. and with ADB type:

OR: wipe data :)

cd /data/data
rm -r com.android.vending
rm -r com.google.android.gm
rm -r com.google.android.gms
rm -r com.google.android.gsf
rm -r com.google.android.gsf.login
exit

reboot system (in cwm)

and after this u need to re-apply the Google Play Services Battery Drain Fix:

http://xdaforums.com/oneplus-one/general/guide-google-play-services-battery-t2832525

btw: I've also found a way to prevent wipe data for the CM Profiles .....

Just delete that file...:

open FileManager and go to:

/data/system and delete: profiles.xml

reboot the Phone.. and the new CM Profiles should appear :highfive:

btw: BLN with blink finally works again :victory:
[Galaxy Ace II Android Development] ace2nutzer:
On my CodinaP everything works fine ....

Are u sure that used codinap CM11 ??

Otherwise:

make sure that u've first latest Stock JB 4.1.2 (MG2) installed ... and then wipe data and flash the codinap CM11..

or u've just formated /modemfs in cwm ?!

If yes, search for a fix from user: fluffi444 The Fix is called something with: No Baseband or Baseband XXX ;)
[Galaxy Ace II Android Development] jasanfer:
