Previous kernel was built using JB source code as base, now we are now using KitKat source as base.
[Galaxy S 4 Mini Android Development] singh54:
Have Doubt....

Hi Thanks for the Work Bro,

But i have a doubt. Right now i'm in CM 11 with ur JB based Kernel.... Should i just flash this new kernel just over that or i have to do any steps? Like clean cache and dalvik cache.... etc etc......????
[Galaxy S 4 Mini Android Development] F4k:
Just flash it, there's no need to wipe cache neither dalvik cache, but you can do it if you want.
[Galaxy S 4 Mini Android Development] bongster:
Hi there,

Arco implemented otg some time ago, do you use the same way? I'm asking because I had a wakelock with your kernel after using a usbdisc and with stock cm11 kernel not. (I tried a couple of month ago)

Thanks for your work!

Hi,

what's the difference between f4ktion_X.x.x-eur_lte.zip and f4ktion_lp_pre4-eur_lte.zip ?

Thanks
[Galaxy S 4 Mini Android Development] TNCS:
The file name already tells you: f4ktion_lp_pre4-eur_lte.zip the f4ktion_"lp"_pre4.... the "lp" is for Lollipop, where as the other one is for the 4.4x KitKat.
[Galaxy S 4 Mini Android Development] ralex76:
Thanks! ;)
[Galaxy S 4 Mini Android Development] ralex76:
Hi, just installed your custom kernel ( 3.4.0-f4ktion_lp_pre4-eur_lte)...could you please suggest me what settings should I change for best performance and battery savings?

Or Better...which I/0 scheduler and cpu/governor do you suggest me?

How should I set up voltages?

I just installed voltage control lite where I could change the parameters above mentioned...

Are there any specific apps to modify the parameters you have indicated on the first page ? Or can I do it by using the menu of the custom rom?

thanks
[Galaxy S 4 Mini Android Development] GNUDroid:
Using the new cm11 kernel 1/2 day. Works fine. Somehow GPU settings are not accessible anymore (like up threshold) but that do not bother me.

Tried new intellimm. Can not say too much about deepsleep because if unusual use of my phone today. But: up thresholds have to be adjusted down to 80% otherwise laggy. But it seems on use of phone a energy saving. Tomorrow I will test more deep sleep. ... Let's see if it can replace my favorite smartmax.

Thanks for all the work!
[Galaxy S 4 Mini Android Development] F4k:
That GPU feature is not yet implemented.

Hello [MENTION=3261191]F4k[/MENTION] , I would like to ask: is it technically impossible to deliver power to the usb port for OTG? I'm asking because I have bought a Kingston DataTraveler MicroDuo for my tablet and it works great using ES or StickMount, but of course, it doesn't work on my S4 Mini. Not complaining or anything, just asking if it would technically be possible! Thanks for your kernel and great ROMS!

Hi,

Had an issue with this one, I was unable to play music using DoubleTwist app, logcat showed an error with something like "Cannot start MP3 decoder"... Can post full logcat if you want.

[MENTION=3261191]F4k[/MENTION], I switched to F2FS today, only '/system' keeps reverting to ext4. What can i do about this?
[Galaxy S 4 Mini Android Development] Aronuser:
System is faster with ext4 that's why, because it's read only
[Galaxy S 4 Mini Android Development] lombartz:
[MENTION=3261191]F4k[/MENTION], is it a big deal to add support for charging in USB-OTG mode ?

happy new year...

lombartz
[Galaxy S 4 Mini Android Development] bassie1988:
Thanks mate! Didn't know that..:thumbup:;)
[Galaxy S 4 Mini Android Development] LanderN:
Actually, it's because the ROM install script formats system to ext4, you'll have to change the script (description in the All-F2FS thread)
[Galaxy S 4 Mini Android Development] jukyO:
Sorry for the OT. But you are talking nonsense.

Filesystem type (ext4/f2fs) has nothing to do with permissions.

Permissions of the rom, here on '/system' partition are done during flashing (look at the updater-script in ROM zip).

Mount of "/system" is done in RO mode per default

RW is achieved through superuser/supersu, not with filesystem type (ext4/f2fs).

Difference between ext4 and f2fs:

http://xdaforums.com/showthread.php?t=2697069

More on f2fs:

http://en.m.wikipedia.org/wiki/F2FS

So better performance and more durability for flash are key advantages of f2fs over ext4.

Cheers,

jukyO
[Galaxy S 4 Mini Android Development] Aronuser:
What i wanted to say is the the read time is faster with ext4 that's true or not?
[Galaxy S 4 Mini Android Development] mielletseed:
He didn't write about permissions but about the fact that the /system partition normally is mounted read only and in normal use only be read from. There are almost zero write operations to /system while normal use ...
[Galaxy S 4 Mini Android Development] jukyO:
Didn't check the benchmark in detail. In some aspects ext4 is better, in some f2fs.

But for sure, RW/RO is not the parameter which determines performance, what you initially mentioned.

Cheers!

Hello [MENTION=3261191]F4k[/MENTION],

Now that I am running cm-12-20150106-NIGHTLY-serranoltexx should we also use the pre4 kernel or the kernel in this thread should be the one to use?

I hope my question makes sense!

Luis
[Galaxy S 4 Mini Android Development] F4k:
You should don't use it, on stock kernel included in CM12 SELinux is set as enforced, on my kernel is set to permissive plus there are some important differences on ramdisk side and in the kernel itself.

I'm using right now an updated version but SELinux is set to permissive, if I set to enforced, some things like FauxSound doesn't work properly so I need to work a little on it to use SELinux as enforced.
[Galaxy S 4 Mini Android Development] llapao:
Understood. May I ask if you are working on a kernel for the last CM12 nigthly and the ones that will follow it?

:)
[Galaxy S 4 Mini Android Development] F4k:
This answer your question, I could release this variant today, but SELinux will be set to permissive for now.
[Galaxy S 4 Mini Android Development] davze:
I think it would be very much apreciated since the stock kernel is a battery killer. :)
[Galaxy S 4 Mini Android Development] gian90t:
Can i use this kernel with any 4.4.2 custom rom ??

Yes, if the custom ROM is AOSP-based.

Excuse dumb question, is "sod" sleep of death or something?

I used 1.6.3.5 on narkoman's miui and it never woke, then after reboot I had no data and then no signal so I'm back on 1.5.7

1.5.7 works very well was just looking at newer to see if cpu stuff was different.
[Galaxy S 4 Mini Android Development] cojocar.andrei:
I don't think this is it. With the same settings for kernel on 1.6.1 it works ok, besides the bln light remaining lit, on 1.6.3.5 it takes 10-20s to wake up. This is too much. There's something that's interfering with the wake up. Same settings with the 1.6.3.5 on slimKAT work ok...
[Galaxy S 4 Mini Android Development] TiTAN-O-One:
I dont use BLN so i cant test out BUT im facing the 10s-20s wakeup thing. Its been like this since prev version :rolleyes:

[Galaxy S 4 Mini Android Development] cojocar.andrei:
Maybe F4k have time to look into it. It would be great to have this kernel working ok on other roms. The "bug" was introduced after 1.6.1 kernel. In 1.6.1 it works ok.

hello!! I am using f4k lastes release with cm12 official, just fresh installed today in the afternoon, I was using cm11 with f2fs in /system, /data and / cache, now I am using the same procedure but only in /data and /cache and when I format cache and rom starts cache partition is automacally mounted as ext4 filesystem. Why could be that? I've tried with TWRP 2.8 by f4k CMW by philz recovery
[Galaxy S 4 Mini Android Development] thejester123:
Cm 12 probably doesn't support f2fs filesystem
[Galaxy S 4 Mini Android Development] F4k:
I could not tell you, I've not tried official CM12 but I'm using f2fs on cache and on my extsd with my custom CM12 build.

If you use my TWRP build, be sure that you tick 'Force data and cache wipe functions to use F2FS' under Settings.

Hi, i cannot get BLN feature working for almost 1 year.

Latest offical cm12nightly and f4k's latest kernel. it was a clean install.

The last time it was working was on cm10.2. On BLN Pro all services seem enabled are running. Can you please help me i miss the feature!

Edit:

And when i try to disable and enable the feature to get it working, the service informer changes. (Led service is disabled and not running, with green font)
[Galaxy S 4 Mini Android Development] chacox:
I already did it but I get the same!. In fact, I formatted cache partition in f2fs manually from recovery with adb but when s4mini boots automatically mount cache as ext4 anyway. What I am doing now is unmounting, formatting and remounting cache in f2fs directly from cm12.

[Galaxy S 4 Mini Android Development] ozi5783:
i have a little issue with overclocking. no matter what frequency i choose, the max freq remains 1728MHz. underclocking works.

i use f4k's 11.01.2015 unofficial build, pa gapps pico beta 11.01.2015 and f4k's pre5 kernel. clean install

also had this issue with older builds and pre4 kernel.

my device is gt&I9515 using UCNK1 baseband.

anyone has this issue?
[Galaxy S 4 Mini Android Development] F4k:
What do you mean with LPA?

There's not such issue, there's a few ways to make OC works, you can use PerformanceControl, through terminal or you can flash a zip file with your desired OC frequency, check the attached files on this thread.
[Galaxy S 4 Mini Android Development] mielletseed:
Low Power Audio. I installed your kernel and got no sound. I suppose I would have to turn off low power audio in build.prop as in your previous kernels with lpa=false and I wondered if you plan to support low power audio with your kernel too. First it's a little bit annoying to turn it of after every flashing and second I'm hoping that it would consume less power ;)

When I tried to make a picture the camera just said: cannot find external storage, please insert SD card.

However, from file manager I was able to access the external card, but looks like mounted in a non standard location.
