[Samsung Galaxy Grand Quattro] :
No bugs or minor problems? If everything is working,still Thank you for your support and testing :)

Such as force reboot and crashes for no apparent reason because the tweaks they are just like optimising things therefore sometimes it may affect the kernel
[Samsung Galaxy Grand Quattro] id74em8:
No apparent problems faced yet. Governors seem to work fine.

You said if I install task killers, I might encounter problems. What kind of problems?

Same here.
[Samsung Galaxy Grand Quattro] :
The problem is with the LZO compression.I will fix end it when I have time
[Samsung Galaxy Grand Quattro] hardikkhara555:
Hey bro does this kernel support swap??
[Samsung Galaxy Grand Quattro] tiger411:
now V3 update 9/03/2014 works.
[Samsung Galaxy Grand Quattro] pranshujain:
please give the download link for the latest build ?
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
I have overheating problems in ver 1 of kernel and is v3 stable and without overheat and random reboots???
[Samsung Galaxy Grand Quattro] :
Random reboots is fixed.Overheating depends on your usage because if you put the display to the maximum and continue to use for straight three hours+,you definitely will faced overheating because its normal to every Samsung devices
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
No sir I keep screen brightness at minimum and it overheats while charging and light gaming for abt 10 mins on ver 1
[Samsung Galaxy Grand Quattro] :
The kernel shouldnt be causing the phone to overheat.There is no overclocking presented in it at all so might be other issues
[Samsung Galaxy Grand Quattro] lols21.10:
Yeah bro it might be some other problem cuz i myself is using this kernel and never faced this problem well sometimes when i play heavy game for about 45mins
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
Is there any word about new update??? Sir can you upate this kernel to latest kernel version by applying patches from kernel.org???
[Samsung Galaxy Grand Quattro] :
Project Engine Kernel™[Charlie Build 3][Update 9/3/2014]

Yup it might not be easy because you will faced lots of bugs when updating to new Linux kernel versions.I will work on it when i have time but currently having major exams so i am not really fully active in developing

Are you having board's too?
[Samsung Galaxy Grand Quattro] El_Dark:
Guys, sorry for the noob question but, how do I backup my current kernel?
[Samsung Galaxy Grand Quattro] :
Backup whole ROM then if any issues caused,go to CWM and use advanced restore and restore boot
[Samsung Galaxy Grand Quattro] mski.L337:
Came from a hard bricked Quatro... motherboard got toasted up when i was doing some stuff to make this device better, anyway, with that set aside, i can fairly say that this new kernel did such a fantastic job for our quatro. i know that this kernel is still in its basic form but it gets the job done..

-no overheating problems

( specifics would be -if you play too much games or do things that requires more power then the phone gets warm [span of 45 mins and up or any numbers closer to that.. its juz logic. )

-our mobile phones aint desktops that can accommodate heavy tasks "straight" although smartphones now has been very promising and it will in the near future, lets try not to forget the basics and not to overwhelm ( too much ) some low devices its limitations with bricked phones as end results.

:good: for OP

-smartassv2 1008

-sio 320

:p next update should be a major one hahaha
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
Did you brick your phone with this kernel??? I have been using thus kernel v3 and there are no bugs till now and what do you mean by smartass 1008 and sio 320
[Samsung Galaxy Grand Quattro] Jasi2169:
use terminal emulator to backup boot.img
[Samsung Galaxy Grand Quattro] mski.L337:
-sorry for this late rply sir...was busy..

-no this kernel did not brick my device...this kernel is great.

careful when installing native scripts such as a2sd, and some kernel tweaks

which are not supported in this device..

will hard brick your quatro.

-1008 smartassv2

320 sio

my current setting for this kernel.. good with battery smooth ..........
[Samsung Galaxy Grand Quattro] ChaosClown:
message to dev

hi dev make the kernel support S-Tweaks 4:confused:
[Samsung Galaxy Grand Quattro] :
S-Tweaks only support Siyah kernel and most of his tweaks are not compatible with Grand Quattro due to different processors,GPU,screen
[Samsung Galaxy Grand Quattro] ChaosClown:
OK thanks 4 ur replay

have u try to port kernel
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
not to offend you sir or anything like that but can you tell us when are you releasing next version of kernel ??? And will will be new features ?? Im very sorry if i disturbed you during exams
[Samsung Galaxy Grand Quattro] yash.raj022:
HAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH

After using this new Kernel a few weeks...my vibrating device is no more working so unrooted my phone and make the SYSTEM STATUS: OFFICIAL by triangle away and anded it to SAMSUNG LAZY SERVICE CENTRE they will fix it free cuz my phone was in warranty hahaha!!!!
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
Well its your fault I've been using this kernel for a month now and I didn't find any bugs you must have flashed it wrongly
[Samsung Galaxy Grand Quattro] yash.raj022:
My Fault?

Are You jokeing?

I did everything samse as the installation guide!!

Everything gone right!
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
There are So many users using this kernel and none of them have this problem yet so it must be your fault had you installed any other tweak or something g
[Samsung Galaxy Grand Quattro] :
You are responsible for your own phone.Its either you tweak your phone a lot or you install other things on your phone which made it faulty.Other users are not facing any problem so please edit your post and this is a development thread,stick to development questions and not post about what happen to your phone

Off-topic questions can sometimes lead to flaming so be wary of what you are posting
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
Does this kernel have powerHal
[Samsung Galaxy Grand Quattro] El_Dark:
[MENTION=5367286]TripRex[/MENTION] it'd be nice to have inbuilt init.d support for a next release :fingers-crossed:
[Samsung Galaxy Grand Quattro] lols21.10:
[MENTION=5367286]TripRex[/MENTION] can you build any custom rom for our device like you build for grand duos as their does not seems to a hope for any rom near future for our device
[Samsung Galaxy Grand Quattro] :
Will add it in when i have time :)

But i need a working Cyanogenmod device tree to compile a custom ROM
[Samsung Galaxy Grand Quattro] El_Dark:
If any device tree, you might want to ask [MENTION=4686683]bieltv.3[/MENTION] and [MENTION=3862405]SpaceCaker[/MENTION] :) they built CM7.2 and CM9 from scratch for the Galaxy Ace-i (device that I used to use, now my nephew uses it :P)
[Samsung Galaxy Grand Quattro] lols21.10:
Well I am not sure but this one probably work as the creater do update

[Samsung Galaxy Grand Quattro] mysteryno46:
I'm very happy using this Kernel.

Hey [MENTION=5367286]TripRex[/MENTION] Have been using it from a long time now. Already a happy user. Thanks to [MENTION=5126807]ZANKRUT.DOSHI[/MENTION] for recommending this to me.

I am posting this reply just to ask if we can expect a latest release with great features :p any sooner? I know you might be busy but your kernel is most awaited than any kind of Custom Rom. Wish you all the best. Cheers ! ! !:fingers-crossed:
[Samsung Galaxy Grand Quattro] :
He abandoned it long ago

Currently need study for my exams so not really sure when i will have the time to update the kernel so check out for new stuff if i post
[Samsung Galaxy Grand Quattro] mysteryno46:
No issues at all.

No issues at all. :good: Hope your exams goes good and your back on development soon. :victory:

Thanks.
[Samsung Galaxy Grand Quattro] j3toxic:
does the Charlie Build 3 works fine with Baidu Rom??
[Samsung Galaxy Grand Quattro] :
It works on any stock ROM

It works on any rom
[Samsung Galaxy Grand Quattro] j3toxic:
ohk so it means it wont work on Baidu rom as it is a custom rom?
[Samsung Galaxy Grand Quattro] mysteryno46:
Why don't you give it a try?

Just keep the nandroid backup of your working Rom.

Check and let everyone here know what's the result.

All the best

[Samsung Galaxy Grand Quattro] zanini007:
Hmm, what the vantages of each governor?
[Samsung Galaxy Grand Quattro] :
Quattro Version 1.0 Released

From now onwards,the kernel has stepped out of the beta stage to the stable stage.Hence,it will now be named from Version 1.0+++

* New features such as Futex ported from Linux 3.13+ to Linux 3.4 Kernel

* Init.d support through kernel coming soon!

* Optimised Timer slack

* Project Engine Flashable Zip(Please test and report,if you do know how to fix the installation aborted,kindly PM me)
[Samsung Galaxy Grand Quattro] mysteryno46:
So far so good. Flashed it and No issues till now neither I can feel any difference from the charlie build.

I technically don't know what difference Futex and timer slack would be making. But can feel any change. It would be nice if you can share yhe benefits of the additions you made to charlie build. :)

[Samsung Galaxy Grand Quattro] ngaia:
Can you make this device support OTG? I heard it has to add something in kernel to make otg support... the most thing i want is otg suport for this device.
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
Why is everyone demanding otg support?
[Samsung Galaxy Grand Quattro] ngaia:
because otg is the bigest missing feature in this device imo :)
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
when i was using version 3 delta of this kernel , once this phone had got discharged When i put it back to charge and switched it on , it did not boot and went into a bootloop . i had to factory reset my phone Is this bug present in the quattro version too?? I wasnt using any tweak or anything else
[Samsung Galaxy Grand Quattro] freitaz:
Well, I am using the latest version of this kernel, my device already discharged a few times and it's working fine :good:
[Samsung Galaxy Grand Quattro] :
Might be the ROM side problem
[Samsung Galaxy Grand Quattro] ZANKRUT.DOSHI:
i see many new commits have been pushed to gituhub is a new update on the horizon???:D:victory::victory::laugh:

[MENTION=5367286]TripRex[/MENTION] if you are give some tthen can you please change the kernel source to become compt. with cm10.2
[Samsung Galaxy Grand Quattro] :
In order for me to make it compatitable with cm10.2,i need to remove Samsung Exfat driver to support CM drivers but currently now there is no cm 10.2 for grand quattro yet so this will be a next time
[Samsung Galaxy Grand Quattro] lols21.10:
but we need cm10.2 kernel for it to compile :)
[Samsung Galaxy Grand Quattro] Shrukul:
Yes as [MENTION=5021288]lols21.10[/MENTION] suggested, making a kernel compatible with cm10.2 would be really helpful... All the cm10.2 builds have not booted and i couldn't take logcat as my pc wouldn't detect the device...:( Hence couldn't discover if it was rom problem or kernel problem... As you are quite an expert in kernel building, would u please build cm10.2 compatible kernel??:confused::confused:

Also i am trying to build cm10 and cm10.1 for quattro as well.. will the stock kernel source from opensource.samsung.org work for both??.. or should we make some changes in the kernel source?? cm10 is 4.1.2 and our device has 4.1.2 so i dont think we need to make kernel source changes but you are the expert and hence am asking you! :laugh:
[Samsung Galaxy Grand Quattro] :
You can only make CM 10.1 source not CM 10 becos Grand Quattro doesnt have ICS.First you need to remove the exfat driver from Samsung opensource and some other modifications to make it work.Use logcat and dmesg to spot the errors if its not booting and use TheWhisp device tree for reference since he is a RD in Qualcomm developing
[Samsung Galaxy Grand Quattro] Shrukul:
Thank you very much.. :Dand it might be helpful if you could clear another doubt..

This is what i found in k2wl device tree's boardconfig.mk

## Filesystem
BOARD_DATA_DEVICE := /dev/block/mmcblk0p24
BOARD_DATA_FILESYSTEM := ext4
BOARD_DATA_FILESYSTEM_OPTIONS := rw
BOARD_SYSTEM_DEVICE := /dev/block/mmcblk0p21
BOARD_SYSTEM_FILESYSTEM := ext4
BOARD_SYSTEM_FILESYSTEM_OPTIONS := rw
BOARD_CACHE_DEVICE := /dev/block/mmcblk0p22
BOARD_CACHE_FILESYSTEM := ext4
BOARD_CACHE_FILESYSTEM_OPTIONS := rw

## Partition sizes
BOARD_BOOTIMAGE_PARTITION_SIZE := 12582912
BOARD_RECOVERYIMAGE_PARTITION_SIZE := 12582912
BOARD_SYSTEMIMAGE_PARTITION_SIZE := 1258291200
BOARD_USERDATAIMAGE_PARTITION_SIZE := 5573804032

and this what i found in TheWhisp's boardconfig.mk

## Filesystem
BOARD_DATA_DEVICE := /dev/block/mmcblk0p18
BOARD_DATA_FILESYSTEM := ext4
BOARD_DATA_FILESYSTEM_OPTIONS := rw
BOARD_SYSTEM_DEVICE := /dev/block/mmcblk0p16
BOARD_SYSTEM_FILESYSTEM := ext4
BOARD_SYSTEM_FILESYSTEM_OPTIONS := rw
BOARD_CACHE_DEVICE := /dev/block/mmcblk0p17
BOARD_CACHE_FILESYSTEM := ext4
BOARD_CACHE_FILESYSTEM_OPTIONS := rw

## Partition sizes
BOARD_BOOTIMAGE_PARTITION_SIZE := 12582912
BOARD_RECOVERYIMAGE_PARTITION_SIZE := 12582912
BOARD_SYSTEMIMAGE_PARTITION_SIZE := 524288000
BOARD_USERDATAIMAGE_PARTITION_SIZE := 979369984

See there is difference in partition sizes in both.. which one should i use??

The k2wl device tree is for cm11 and TheWhisp is for cm10.1...

and also do these values remain constant for every cyanogenmod version or it differs for different versions??

And also which file system to use??

And lastly, will it be ok if i use k2wl's kernel source to build cm10.1?? it is actually for cm11 but what if i use that for cm10.1?? or else use androidarmv6 msm7x27 kernel source and copy the cyanogenmod_delos3geur_defconfig from k2wl to androidarmv6 kernel source??

[Samsung Galaxy Grand Quattro] El_Dark:
Trip, are you adding the init.d compatibility in next version? :)

Oh, did I mention that the test went out smoothly? :P
[Samsung Galaxy Grand Quattro] yajnab:
I think the Github repo of this kernel is not updated with the release of this kernel. Its breaking the XDA and GPL rules.
[Samsung Galaxy Grand Quattro] :
Its imported from the Samsung OpenSource Kernel.zip and the necessary commits is to keep the authorship of others in the kernel.Its in my Github if you will like to check www.github.com/Triprex/android_kernel_samsung_delos3geur

Furthermore,i have use others as a reference and those who imported from Samsung Opensource Kernel zip did not have any history commits.Take a look at this Recognised Developer and he is in the main team of Cyanogenmod and from here,i can see that it is imported from Samsung Kernel zip without any history commits.The only thing he did is keeping the authorship commits and i dont see why the same thing i did in my kernel repo breaks the XDA and GPL rules?

www.github.com/pawitp/android_kernel_samsung_i9082
[Samsung Galaxy Grand Quattro] yajnab:
XDA and CyanogenMod and totally two different things and you cant merge them.

If you understand the terms and conditions of the kernel it says you need to update your Github or some other kind of Repo side by side with the Release of Updates.

If you look into the changelogs in your XDA and Changelogs in your github you will find many things are missing in the github. I hope its clear to you.

Pawitp has initited the git with the Sammy opensource zip but has updated his github with each and every updates he has made while releasing in XDA.
[Samsung Galaxy Grand Quattro] :
As a matter of fact,if you even look at my previous post.This new kernel version was started again in a new repository and i understand what you are meaning but those are the previous release versions of my kernel.The repository you have now seen is only filled with latest version commits and the changelogs you have seen came from the older repository and now i only had the old files uploaded for users preference
[Samsung Galaxy Grand Quattro] yajnab:
The Link to the new Kernel repository is also not updated
[Samsung Galaxy Grand Quattro] :
The link is working.If you want to try,try it on the browser and you will see yourself redirected to the github link.
[Samsung Galaxy Grand Quattro] yajnab:
The Source is not updated as per your latest releases. Hope you get it.

I cant see the things like

SIO and V/R I/O Scheduler

Timer Slack Controller

Added Frandom support and linked to dev/random

Add extra free kbytes tunable

Android LowMemoryKiller Tweaks-Management of not killable process

Avoid turning off GPU clock if its already off

Smartass2,Hyper,Intelliactive,Lulzactive governors added

Compiled with Linaro 4.6.2 Toolchain

Revert some stuffs and clean up code to fixed random reboots

Introduced Dynamic Sync Control by faux123

Decrease default dirty ratio
