Hi

I've faced weird problem!!!

When I install firmware with /data and /cache partitions fotmated to F2FS , wifi wont work!

All I done is:

Installed zwliew-kernel-20140607-f2fs.zip (just its boot.img with dd to p15 in recovery using adb)

reboot to new recovery and select Toggle ext4 <--> f2fs and formated /data and /cache to f2fs and /system to ext4

Then , installed cm-11-20140706-UNOFFICIAL-codina.zip and finally zwliew-kernel-r1.5.zip and GoogleAps and reboot to bootloader.

I've tried twice but still have this problem and wifi wont work!

Finally I installed firmware and zwline kernel with /system /cache and /data formated to ext4 and problem solved!!
[Galaxy Ace II Android Development] zwliew:
my newer kernels don't have f2fs support so it won't work.

btw to all:

i believe the reboots are related to interactive governor. please use ondemand governor for now until i look into it.
[Galaxy Ace II Android Development] sorset:
But I after toggling to f2fs and formating /data and /cache partition to f2fs it boots without any problem.(I checked that they are mounted as F2FS automatically) it obvious that r1.5 fully supports F2FS.

I think problem is something in toggle mechanism and make wifi wont work.In the meantime after disable toggle and reformat /data or /cache to ext4 , it wont boot and I should reformat /system and reinstall firmware.
[Galaxy Ace II Android Development] ace2nutzer:
Yes i think yo are right.. on latest build even on stock CM 11 Kernel, interactive is very buggy.. sometimes the freq. don't get back to 200MHz.. it's hang up by min. 600Mhz.

But why BLN is reverted to old driver ?! I don't like the old Driver.. it has no blink.. and it's stay on for ever.. very bad :(

The new BLN Driver worked perfectly for me..

And what about the Trebuchet Issue ? (Settings) - Until Build 2014/06/07 works, on the last 2 build not..
[Galaxy Ace II Android Development] zwliew:
how are you checking that it is mounted with f2fs? r1.5 doesn't have f2fs so it can't be that you are mounted with f2fs. check if /sys/fs/f2fs exists.

what trebuchet issue? probably not related to kernel. bln is reverted to old driver because we(tc) thought that new driver called no blink mode to stay on forever. we'll look into bln soon.
[Galaxy Ace II Android Development] sorset:
Im sure that i formated to f2fs! and checked partitions with FX File manger and fstab.

I can reinstall firmware witth f2fs and send you photos of it ;)
[Galaxy Ace II Android Development] ace2nutzer:
Trebuchet the Launcher: u can't enter in trebuchet settings.. and perhaps it will be ok when we replaced the apk from working Build ?

Yes it's nothing to do with kernel.

BLN with blink mode works perfectly.. but with wakelock on 2014.06.07 Build.. but on 2014.07.06 Build bln stay on for ever.. and no blink.. even with wakelock.. but i noticed that i don't Use the standard Softkey lights.. The Softkey LED's are always off i don't use it.
[Galaxy Ace II Android Development] sorset:
In fact thats not the point wheter it supoorts f2fs or not.

My question is , why wifi will not work if I toggle and format to f2fs?!
[Galaxy Ace II Android Development] zwliew:
that driver was reverted in previous builds of tc cm11. we'll look into it.

as i said, my kernel doesn't support f2fs. if something automagically happens if u do anything related to it, i don't really care because there is obviously something very wrong.
[Galaxy Ace II Android Development] sorset:
Well it seems it's NOT your kernel because you have no idea that this kernel supports F2FS perfectly and in fact the kernel is belong to Linux foundations and is under GPL. It's just about its conflict with wifi!
[Galaxy Ace II Android Development] zwliew:
whatever you say lol. did you update the modules?
[Galaxy Ace II Android Development] acrocosm:
BLN has only worked well for me in maclaw builds. TC cm11 and PA, that I use now, both have/had problems with either new or old driver
[Galaxy Ace II Android Development] ace2nutzer:
Yeah.. by default don't work.. but if u enable manually wakelock.. then it works properly ;)

Or simply activating Double Tap 2 Wake !.. That enables wakelock also. :D
[Galaxy Ace II Android Development] doctormord:
Well, it seems to me that the whole kernel thingie is a way to "overoptimized" if even now interactive is not working properly anymore. I remember older builds that worked way better.

Beside this,

TC stock kernel is working nicely here, with BLN, with 200Mhz, with no reboot on 1200. (untouched) I actually don't understand, why so much people having problems with their phones. :eek:

Starting from a clean install is always the best option. (Stock ROM -> TC ROM -> Kernel)
[Galaxy Ace II Android Development] ace2nutzer:
Because they have s6d display Chip ... in this case i read only ROMs with TWRP recovery works
[Galaxy Ace II Android Development] farru1981:
New bug?

Hi I think I have found a new bug on bluetooth side.

In my car I use a Parrot CK3100 for handsfree and an Alpine CDE-183BT for A2DP.

If I do a call the BT Media connection of the Alpine gets dropped and I have to connect it again, but the BT Parrot handsfree does not get disconnected.

If I use the Alpine for everything (handsfree and a2dp) everything works as it is supposed to be, but I prefer to use the Parrot for handsfree because it have more quality on audio calls.

This doesn't happens on stock CM 11 TC kernel.

I am using the 15.06 kernel release because the r1 and r1.5 crashes a lot and reboots constantly. Also I can't use the stock CM11 TC kernel because it suffer a lot of audio stuttering when a new notification arrives :crying:

Regards,

PS. Sorry about my english, I am learning...
[Galaxy Ace II Android Development] zwliew:
sorry guys, i'm discontinuing this project. it has been a great journey venturing into this 'mysterious realm' of kernel development. i've gotten my oppo find 7a(great phone) and will be working more on that instead of codina.

however, that does not mean that i'm completely leaving. i've merged quite a few commits to the teamcanjica cm11 kernel, such as the interactive governor improvements(much better than pretty much any other governor now) and lz4 kernel compression(faster boot). i'll be contributing to the stock teamcanjica kernel now instead of this kernel.

thanks for all who supported me these past few months and it's been great! cheers :highfive:
[Galaxy Ace II Android Development] tofueatsbread:
Good luck bro :)
[Galaxy Ace II Android Development] MarquesYOLO:
Thank you for all your work zwliew.
[Galaxy Ace II Android Development] ace2nutzer:
Nice to hear zwliew !! we all loocking forward with u !

I find it will be very nice if TC CM 11 ROM will support F2FS for the System Partition ! :fingers-crossed:

I know u can it ! :D:good:

And i will continue finding good safe and stable voltages for all. Stability test's are running with Stock Clocks / Voltages for now to testing the ground stability of the ROM .. and to test if my Phone is OK :D...).. and later with oc and custom Voltages. I think this is the best way.

I already compared Stock Voltages with Cocafes custom Voltages (TC CM11 Default) and i find important informations.. but more comes later from me, be patient.. plz don't pm me, about this stuff.

if you want to help me all, for a standard, stable voltage which we can then use for all, then flash the stock JB and check under /d/ab8500-regulator/status and send me via pm an screenshot! The more get involved the better. But I think we would have already have 20 screenshots to make it accurate !

I will post the screenshots here in this post (all) if this is OK for zwliew !!

With this informations a can make stable voltages even for extended Steps... because the extended Steps will help for powersave and stability IF the Voltages are setted correctly ! :highfive:
[Galaxy Ace II Android Development] xo.en:
..so one man less, that was able to make 4.3.x kernel for good older roms...ehh.
[Galaxy Ace II Android Development] Kiras_PL:
Works pretty well. But best for me is interactive governor. Thanks!

[MENTION=5604178]zwliew[/MENTION]

Maybe it's too early to judge, but after ca 10 hours of using that kernel (2014-04-23 of course) i can say, that freezes are gone (on carbon ROM). Thank you..

I'll continue my test and will see...
[Galaxy Ace II Android Development] Rox:
I guess ( i am preety sure ) freezes are coming from tweaked readahead buffer size. there are soem fixing commits from cocafe i guess it will solve issues on our stock roms kernels :)
[Galaxy Ace II Android Development] judas1977:
@up

it's very possible, because after last freeze i changed readahead settings to 128;))
[Galaxy Ace II Android Development] Rox:
I did it too, no freezes till now. Are you using 512kB with this kernel ?
[Galaxy Ace II Android Development] judas1977:
Hmm, it is set to 512 indeed

Btw, i compiled twrp kernel for thinking bridge based on zwliew sources, but I'm too sleepy for install that Rom and test kernel, so i try tomorrow

Send... i hope so
[Galaxy Ace II Android Development] Rox:
I have just commited some commits from zwliew. Actually i think makefile optimizations are not needed because we already set them in boardconfig, but it wont hurt. Maybe somebody wants to build for stock, he will need it...
[Galaxy Ace II Android Development] dragos281993:
The "zzmoove" governor isn't working as it should. The 2 cores the phone has aren't working together and that results in a serious lack of performance. "Core0" works very hard to make the device work properly, the frequencies alternate from 200 MHz (minimum) to whatever you set (maximum) and it looks good, but "Core 1" is very lazy and after it works a few moments, goes offline the starts againg, then goes offline again, and it doesn't keep up with its twin. The CPU hasn't got a very good clock speed but being a dual core, the story is different. But as long as only one core works well and the other one goes to sleep every time it has the chance, the device will be super slow all the time. So "zzmoove" is pretty much useless. I hope I helped you
[Galaxy Ace II Android Development] zwliew:
Yes, I know that. Can you try setting mulicore power saving to disabled on novathor settings and see how t goes?
[Galaxy Ace II Android Development] JuraP:
Hallo zwliew , is this kernel suitable for P version or just for GT-I8160? THX in advance.
[Galaxy Ace II Android Development] exodius48:
Whre is the LiquidSmooth.. ? :(
[Galaxy Ace II Android Development] nicknitewolf:
I dont think that is compatible... But u can try...
[Galaxy Ace II Android Development] pedroleon99:
For now is only for GT-I8160 because an user (a few pages back )tried to install it on P version and give status 6 in cwm

Inviato dal mio GT-I8160 utilizzando Tapatalk
[Galaxy Ace II Android Development] zwliew:
LiquidSmooth should be compatible. Take note, that list is only what has been *reported* to be compatible, not what actually is compatible.
[Galaxy Ace II Android Development] zwliew:
Performance is unrealistic in real use. It locks frequency to maximum, which in this case is OC over 1GHz. This amounts to not only huge battery drain, but also excessive heat generation(which also results in more battery drain).
[Galaxy Ace II Android Development] nicknitewolf:
But it can be used for a period of time to boost benchmark scores (cheating :))
[Galaxy Ace II Android Development] exodius48:
Ok bro

Btw, noob question, how to see if the ROM compatible with this custom kernel? Should I test all features inside this kernel ? or is there a simple way to test it for a newbie like me? hehe..
[Galaxy Ace II Android Development] Cronen:
Just install and tested.

This kernel works fine in slimkat and isn't in roms list...
[Galaxy Ace II Android Development] nicknitewolf:
More people have to report than probably zwliew would put it at OP
[Galaxy Ace II Android Development] exodius48:
Ok, testing...
[Galaxy Ace II Android Development] avithohol:
There are users that are using Performance governor, for benchamrks and tests and even for everyday use, there aren't any benefits in disabling it.
[Galaxy Ace II Android Development] exodius48:
Already used this kernel, but why my RAM now 623 MB, before install 624 MB, please explain me..
[Galaxy Ace II Android Development] judas1977:
@up

OMG, panie premierze, jak żyć

How to live without that 1MB

Send... i hope so
[Galaxy Ace II Android Development] exodius48:
I just wanted to know bro.... haha.. :D

May you explain me?
[Galaxy Ace II Android Development] zwliew:
You shouldn't be testing the maximum performance your phone can go especially when you won't be using it in actual use. The independent governors used in the kernel affects daily performance as well. Even two 'ondemand' governors in different kernels can have different performance.
[Galaxy Ace II Android Development] avithohol:
LOL do what you want, its your project after all, i told you there are users that are using this governor. Do not try to tell me what I should or shouldn't do to my phone.
[Galaxy Ace II Android Development] manthes:
In cm 10.2 it can't boot and i have only black screen. I tried the latest version
[Galaxy Ace II Android Development] zwliew:
New release 20140425!

By the way, does anyone using intelliactive governor experience more battery drain after the performance tweak in 20140424?

Oh sorry, this doesn't work on CM 10.2.
[Galaxy Ace II Android Development] dragos281993:
Just so you know, I reflashed the previous version "...23" because the only stable governor is "performance" when you change the clock speed to anything over 1000 MHz. In the latest build I tried every combination possible between governors and I/O schedulers on all the frequencies over 1000 including 1000 MHz and my phone rebooted when I used the phone more intensively. EX.: I was using Tapatalk Pro last night and I tried to send a "bug report" about the latest build, and my phone rebooted 3 times (the message I sent was the 3-rd try) . Then I downloaded the free version of the app and I managed to send the message, eventually. I didn't give up and I kept trying to see how it goes and I played a bit of "Smash Hit" and again, after a few minutes of use the phone rebooted again and it was on "intelliactive" at 1000 MHz and SioPlus. The last freq 1250 MHz is the less stable of all. Then 1200 Mhz is a bit more stable than the last one but is still unstable and makes your phone stop during a call or something else (it happens exactly when you don't expect). 1150 looks pretty good but you must have the governor set on "performance", because other governor cannot keep up with the clock speed and device will reboot.

Now I have the previous version installed on my device because, from what I've seen, is a lot much stable than the latest one because of the "Performance" governor. But I'm gonna flash again the latest build just to try what you said.

So,just to understand, should I go to "Novathor settings" then "I/O" and disable "Multicore Power Saving"? By default it's disabled so I'm waiting for any suggestions you have. I wanna help you by testing your builds in order for you to create a very stable kernel.
[Galaxy Ace II Android Development] zwliew:
It is really difficult to understand such a huge chunk of text lol. I'm reenabling performance in the next build, but from then on, I won't accept anymore reboot requests for overclocking over 1GHz.
[Galaxy Ace II Android Development] monstro78:
Seems latest build don't boot. Hopefully cwm works.

Sent from my GT-I8160
[Galaxy Ace II Android Development] dragos281993:
From what I've seen, if you set the clock speed at 800 MHz the phone is slower than the kernel without OC at the same frequency. So you should try to build a version with 1Ghz maximum frequency and channel all your force to making it stable. I don't think anyone could manage to make any frequency over GHz stable, because the CPU is not powerful at all and it's probably a pain in the ass to try to squeeze something that cannot give more juice. So my idea for you is to create a kernel with 1GHz max freq, that doesn't drain the battery's juice in a few minutes of hardcore use and be a bit more powerful than the 800MHz. I believe that if you did that, you'd make a great kernel.
[Galaxy Ace II Android Development] zwliew:
That is the point why I don't want to enable performance governor, there is no point in using it with OC over 1GHz, it just drains your battery like no other.

[Galaxy Ace II Android Development] zwliew:
Nevermind, botched update. At least it is possible to go CWM and flash an older release
[Galaxy Ace II Android Development] dragos281993:
The majority of the people most probably wants better battery life than better performance. My phone is always set on "perfomance" and 1150MHz clock speed and sioplus and the battery does a better job than I was expecting. However, it's only a 1500mAh battery, on a device set by default to run a maximum 800MHz freq. We should be aware of the fact that anything over that will drain the battery faster no matter what we do. You can't ask for a great battery life when you're phone is almost on fire. But that doesn't mean we stop using it. If you don't want to build a kernel with maximum 1GHz frequency, you could delete 1250 and 1200 MHz because these 2 are the only ones that will always be unstable, and try to focus on the other frequencies left. But if you manage to make the 1GHz freq stable and powerful, people will probably stop using anything over it, including myself. You shouldn't even reply to those that complain about their battery drain when they're using the phone with everything set at maximum.
[Galaxy Ace II Android Development] zwliew:
Can you tell me what your battery life is with performance? SOT, total time in total, etc.
[Galaxy Ace II Android Development] dragos281993:
Right now the phone is set on "performance" at 1150MHz and sioplus. I have both Wi-Fi and data connection (only 2G) turned on. They're always turned on. The screen luminosity is set at medium (more or less). So now the battery has 51% left and it hasn't been charged for 1day 12hours 15 minutes 58 seconds. So it's pretty good.

hey wifi tathering not working here, anyone confirm it ?, fix it please
[Galaxy Ace II Android Development] dragos281993:
Try this:

-go to settings ->more -> tethering and portable hotspot. Then try to set up the Wi-Fi hotspot. You'll see a field called "Security". Try to change them. First REMOVE the encryption by choosing "NONE" meaning you don't use any security.This way you'll know if the device works as a hotspot router Then set it on WPA PSK. By default the security type is "WPA2 PSK" which didn't work for me either but the other one (WPA PSK) should be ok.

If you still have this issue, read what I said above very carefully and the phone should be working fine as a hotspot device.

PS: If the security type is set on "WPA PSK" by default, then try using the other one. Try to alternate them till you find the right encryption.
