[KERNEL] [Samsung JB] Boeffla-kernel 5.3-beta7 <29-06-2014>

[Hbohd]

Boeffla Samsung Kernel by AndiP
Ported and compiled by Hbohd and P$T
For i9305​

Introduction

Note: The 4.x kernels are only for Samsung based 4.1.x roms!!! Do not install it on CM or AOSP based roms!!!
The 5.x kernels are only for Samsung based 4.3 roms!!! Also do not install it on CM or AOSP based roms!!!

After ausdim's contribution to porting variety of kernels to our phone, I am here to continue his work (he won't maintain it any longer because he simply doesn't own this phone now). Updates will be made as soon as Andi will push them to github.

Here is original thread of i9300 boeffla kernel - CLICK
Here is thread with boeffla ported by ausdim - CLICK

Info

Kernel is compiled using Linaro 4.9.1 with some required changes for our i9305:

• No FM radio
• No CMA_DMA
• No flash and load in Boeffla App
• New 'Hbohd preset' and 'PST preset' which are just our everyday use settings.
• New 'Hbohd' and 'PST' equalizer preset - just our favorite.

Apart from that, everything is same as in i9300 version.

Please for any questions problems or anything else ask here and not on I9300 thread.

Disclaimer

*** As always - Flash on our own risk! ***

Make sure you flash the correct version depending on your firmware version!

I can and will not take any responsibility for bricked phones or lost data.

It is generally recommended to run a complete Nandroid backup in CWM recovery and safely store your personal data before you flash a new kernel.

Camera bug info:

It appears that some people (like me) have problem with camera. In exactly THIS situation: do full wipe, flash sammy rom+boeffla kernel, reboot and launch camera. Effect? Camera closes with "camera failed" popup.

Possible solution:

1. Read this thread and follow steps --> click
2. Flash Sammy Rom with stock Sammy kernel, run the camera, take a photo, then reboot to recovery and flash my ported kernel
3. Flash Sammy Rom with stock Sammy kernel, run the camera, take a photo, grab file (SlimISP_XX.bin, where XX differs between phones) from /data/cfw/ and backup it where you want. Then if you can always copy it to /data/cfw if your camera doesn't work with my ported kernel. (ATTENTION: Unfortunately this file does not always appear - still don't know why )

Possible explanation, my own research:
I found out that people with ZD and GD will have camera working always. Why? Because these (SlimISP_XX.bin, where XX differs between phones) files are packed within kernel (zImage exactly) and ONLY THESE two are provided by Samsung in their opensource release... Interesting, isn't it? For example, I have GH version, which I may add to zImage manually, however adding more of them breaks the size limit for boot partition, so it's impossible to have all these versions together. However, stock kernel somehow has them, don't know how because zImages aren't extractable.

And just to confirm my theory, I've compiled a kernel with mine version of camera firmware, made full wipe, installed sammy rom+my kernel, rebooted, launched camera and voila - it worked

Thus, we has to live with this bug unless Samsung do something about it or someone else proves me that I'm wrong

I compiled it after adding my own script for zzmoove 0.5 settings, so you all have them in boeffla app. Therefore I need to explain what i changed (it is just for testing purposes, I don't know yet if it is better/worse etc).

I enabled early demand (new feature from 0.5 version):


And also enabled lcdfreq scaling with standard values:

Installed let see how it goes...
Good work

Thanks.

Do you have any link or something where we can read about zzmoove governor tunables? I was searching, and searching and nowhere have I found a good explanation of all parameters.

I should probably look into sources you just gave a link for, but I am too tired atm.
Edit:

Oh that wasn't link to sources, but it doesn't matter, there has to be one somewhere in Boeffla thread.

My 'sources' are only one file - defconfig. The rest is completely same as Andi's sources

And for any explanation of zzmoove configurables - there is some documentation, quite well explained: https://github.com/andip71/boeffla-...48257af1b13/drivers/cpufreq/cpufreq_zzmoove.c

Thanks for the port.

Over night I find this one better on battery than the last port. See how it goes with a bit of heavy usage today.

Hi Hbohd. So, let me see if I get it: this port will no longer be updated, and you are now the good guy that will continue to update Boeffla kernel to our beloved I9305?

Yes, you are completely right Ausdim has even mentioned in his thread that he no longer owns our device (i9305) so I decided to ask for his permission to continue his job here !

I am quite in love with usage results of Boeffla kernel, therefore you do not have to worry about frequent updates

 

[ausdim]

Hbohd it will continue the port of the boeffla kernel since i moved to the i9505.

Also i see Andip make some changes to the boeffla sound driver so it will work better.

Thank's

After 1 day with new kernel I can say the battery improve are the best an till now. Great job

Well, I'm sad that a developer leaves this phone, but it is awesome to know that Boeffla will continue to be ported to I9305! The best part is the frequent updates Thumbs up!

I'm gonna try your port and will say something later.

beta6

I found 2.12beta6 very smooth on my wife's s3 (i9300) - is it possible to have beta6 for our device? (i9305)

What if I told you...

Beta7 is better than beta6

Thanks for your work.

Do you have any information about problems with distorted sound? It happens randomly here, and someone else reported the same here in this thread.

Have you used Perseus kernel? What do you think about 'Master sequence', that is calibrated colors? I am missing that feature (well, that colors.) a little, so I'm just asking if there is any chance we get it too, or you plan to stay strictly with pure Boeffla source?

Beta7 is with zmoove 0.5 which is unstable at the moment - beta6 with 0.3
Besides beta6 is so great on my wife's phone that I'm afraid of changing anything

Sincerely, I haven't experienced any random distortions of sound, everything works great. Obviously, if you raise headphone or speaker volume too high, it may be distorted, but it is understandable.

Or did you want to mention the problem with distorted/freezing/stuttering audio on screen-off? That was discussed and it might be caused due to too low screen-off frequency or too high sampling_rate and sampling_rate_sleep_multiplier. If it's the problem, try to change to zzmoove-optimised as it has this values changed a little bit.

About Perseus' screen calibration settings... As for now, introducing such thing would require adding multiple scripts to support variety of configurations for it (in boeffla app), change app to stweaks (which is quite tough task) or wait for new app which will come in some time, made by Andi (and in my opinion, will let us easily configure what we want).

What's more, personally I liked these calibrated colours, however, original colours also seem good to me So nowadays, I do not need it, although I might look at it in my free time and see what can I achieve

The fact is, that ausdim released beta4 or 5, I don't remember exactly, and then was my release beta7. And we somehow skipped beta6, you are right! However if I were you, I wouldn't take zzmoove 0.5 as 'unstable'. It introduces a great deal of new configurables that, I suppose will be really beneficiant in the future (when we all will learn what they mean ).

Version 0.5 is ONLY unstable when you are changing governors frequently. Otherwise, it is really efficient and bettery-friendly one (same as 0.3). In addition, it's my beloved governor since its start

Furthermore, new betas always consist of other updates (like Linux kernel upstream to 3.0.82, fixes, optimizations) so it is always worth to use the newest one!

As for now, you may stay with your actual beta version or wait for next update. Andi is testing comparison between zzmoove 0.3 and 0.5 right now, so he haven't pushed any sources, therefore I can't release any new update We are all impatiently waiting for the results i think!

Anybody experienced a problem when the phone CPU is stuck in the max CPU frequency when the phone is plugged in to the PC using USB connection?

I'm using zzmoove battery profile..
