Hi everyone.
git repositories is the best modern way to work with Linux Kernel sources, designed by Linus himself in this purpose.
Today Samsung release sources as plain tarballs, often with a few missing files and it makes collaboration between developers difficult: instead of merging branches or patch in 2 commands, it creates a lot of headaches.
But also community fragmentation!
Sources are available now, source code will be shared here here as common reference point.
Also, benefit of this approach is free cleaned up upgrades when Samsung releases new sources for everyone.
Stay tuned, and contact me if you're an experienced developer that want to be involved in this source organization: https://github.com/GalaxySII

So samsung will publish the source code on there or you will? Sorry I had trouble understanding - if samsung is that's great news!
good deal dude

Samsung will very probably release sources as a plain tarball.
But we are working to fully integrate the Galaxy S II sources they will release with Samsung mainline kernel repository on kernel.org.
http://git.kernel.org/?p=linux/kernel/git/kki_ap/linux-2.6-samsung.git;a=summary
In order to get the best quality source, easiest to upgrade etc.
Okay Galaxy SII sources are not available yet, but I messed with different source repo to make a clean starting point that will serve as base for the Samsung source drop.
Contains stuff from Linux 2.6 , Linux 2.6.35 stable (2.6.35.7) and linux-2.6-samsung.
Added initramfs !

message to moderators: STOP RENAMING MY THREADS!
Especially with the most useless, unrelated and stupid name: "[KERNEL] coming soon..."
Thank you.
Sources are UP!
I somehow manually re-created commits from Samsung archive.
Before merging Samsung ED24 SHW-M250S sources, I created on a big merge branch named 2.6.35.7-samsung-android, containing
- 2.6.35
- Samsung mainline repository 2.6.35 (merged)
- 2.6.35.7 (merged)
- android 2.6.35.7 (merged)
Awesome!!! Wow! With developers like these we are sure in for a wonderful time ahead. Device got released in UK on May First and already we are seeing such development!! Thank you!
you actually took the time to split the commits by hand into categories
thats cool!
I just threw 5 euros your way for your work on Voodoo for the i9000, and also for the new work on the i9100. Seems fair since I used the kernel for the entire life of the i9000. My next step to pick up the i9100.

Does this mean we have the whole thing? As in: full control of everything from hardware up to UI (drivers, kernel etc)? We "own" the hardware and can do as we please kind of thing?

Interested in knowing the same thing - how much control do "we" got over updates and sorts now? I heard this makes it really easy to update to the latest Linux kernel. Is that true?

kind of but not really. the consensus is that not everything is included in the source that samsung released. i'm just not clear on to what extent this is true.
i'm looking thru to try to find the audio files that could be easily edited to increase volume output, but i couldnt find it yet. maybe someone can shed some light.

There is no such consensus.
Galaxy S II kernel is 100% open source.
Some driver are partially Kernel partially user-space as usual, and we don't have source for those but speaking of the kernel we have everything. (already proven with custom kernels using arbitrary version numbers and no pre-compiled binary kernel module like mine)
Hello,
So far, I have:
A working Android build environment (Ubuntu 11.10 x64).
Managed to build, install and boot AOSP on my Nexus S. (I have downloaded but not attempted to build CM7 yet.)
Created a Github account.
Samsung's open source files for my target device, the Galaxy Gio GT-S5660M.
I've read some documentation and forum posts about Github, but I remain unsure as to what I should do to fork in a way that:
I'll be able to keep on syncing the remainder of the code.
My new device directories and modifications could be brought back (pulled?) to the main CM7 code base.
Will avoid needless frustrating re-downloads of the source code.
Thanks in advance,
Darkshado
After some further reading, I'm beginning to grasp some git basics...
I've forked two CM7 repos so far, added them as remotes in the appropriate installations. (Instead of forking and cloning, since I already had repo sync'ed the whole CM7 source. My commits show up on Github like they should, and I should be able to merge in commits to the origin remotes.)
I'm not going to do any pull requests until I've managed to build and boot.
By the way, yesterday I attempted to build AOSP with a bunch of files overwritten by the Samsung sources (that's how they tell you to do it!!) and this failed, as I expected.
Goodbye,
Darkshado
Update: I'm currently trying to port CM7 to the Gio 5660M. Still attempting a first successful build as I'm writing these lines.
My main issue so far has to do with the camera. I get the following error message:
make: *** No rule to make target « out/target/product/gio5660M/obj/lib/libcamera.so », needed by « out/target/product/gio5660M/obj/SHARED_LIBRARIES/libcameraservice_intermediates/LINKED/libcameraservice.so ». Stop.
After toggling off the camera by using the stub, I hit the same error further into the build with this:
make: *** No rule to make target « vendor/samsung/gio5660M/proprietary/wifi/ath6k/AR6003/hw2.0/athtcmd_ram.bin », needed by « out/target/product/gio5660M/system/wifi/ath6k/AR6003/hw2.0/athtcmd_ram.bin ». Stop.
I know this has to do with makefiles, but that's about it...
Thanks in advance for any help,
Darkshado
hi i'm interested too.
hi I found your github because I also interested poriting cyanogemod to galaxy gio korea(SHW-M290K). the device hardware is different from s5660. so I need some modification.
and your libcamera problem is that there is some reason that the make system can't find libcamera.so, so they cannot compile libcamera service. it should be in ./vendor/samsung/gio/proprietary according to your extract-files.sh .
have one cuorisity. I searched gio android device make file. and none of them are relreased source code. how did you make them?
I found this information. it may help you.
http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_PortingGuides
I'll have to update my Github, hadn't been in a rush due to lack of progress, but now my problem lies with libaudio instead.
I got the Samsung sources for the 5660M on their open source website, although I mostly worked with the CM7 ports for similar devices like Tass and Cooper as well as a Gio source provided by Phiexz but it didn't build either.
Thanks for the link, I'll check it out.
proprietary does not help
do you have any progress since last time?
well, I admit that proprietary files does not help.
does your s5660m hardware identical to s5660v?
becasuse galaxy gio in Korea(shw-m290k,shw-m290s) does different hardware.
well in this case, like me, you need to hack into not only android pdk, but also android kenel.
I have seen that phiexz has released kernel with latest cyanogenmod kenel in his github and I am modifing it to shw-m290k. there are some hardware differences i have to apply to.
I suggest you to compare phiexz's kernel and samsung original kernel from samsung opensource homepage.
My problem right now is that I don't have that much spare time to put into this, and that I'm very much learning as I go, so progress is not always that quick. Also, I'd like to get my Touchwiz based ROM updated and working properly before trying to build AOSP or CM again.
Another thing I want to try is building the kernel (probably based on Phiexz's) that will support ext4, and compare performance of the Touchwiz ROM on ext4 versus RFS.
As far as we can tell, GT-S5660 (Europe/Asia) GT-S5660M, L and V are identical except for the radio firmware. People with the 5660M initially encountered issues after flashing 5660 ROMs because they also contained the AMSS image.
my cyanogen kernel is based on samsung open source kernel
because cm-kernel on cyanogenmod github dont support our device, if we wnt use that kernel we must add some hardware pofile & board for galaxy gio
so alternative is make samsung's open source kernel compatible with cyanogenmod
Wouldn't it be much better from a code maintainability standpoint to make the CM kernel work on the Gio? (Also if you ever hope to get official CM team support, that's a given.)
The way I understand repo and git, you could create a github repo for your device and board configs and add those to your repo manifest so the whole CM7 source and your modifications all sync properly.
I've forked the CM7 manifest files off github, added my gio files and removed all those extra devices I didn't need, so my repo syncs are much faster too. (The idea comes from http://slightlymorethanworthless.blogspot.com/2011/05/remove-unwanted-devices-from.html)
hey a quick question...
just starting out here..
i'm on win7 32 bit, going to run ubuntu on virtualbox.
shud i choose ubuntu 32 bit or 64?
sorry for OT.
doesn't really matter

doesn't really matter. but compiling process needs much cpu power. so 64x would be better.
Well, im not a dev or a user of gt5660m, but good luck to you, hope u can finally port it

darkshado, if you have same problem untill now.
http://strazzere.com/blog/?p=220
look this page. and check out koush's proprietary page. especially for samsung cooper(galaxy ace). because many of kernel procedure are same for gio.

i've upload galaxy gio source + proprietary files for galaxy gio
please see & help to fix some problem

Really the best kernel for your phone is here:
http://forum.xda-developers.com/showthread.php?t=1991020
BLN enabled, optimized&stable kernel, jelly bean look
Whoa! Zombie thread!
Dude: the ROM you linked was published over a year after my original post in this thread. I'm pretty sure there was NO CM7 build available for the Gio back then. That's what I was trying to work on, but got beat to the punch by Maclaw and a couple others. (Hard-bricking my Gio and having a sluggish laptop to build on didn't help.)
Besides, I got rid of my Gio a long time ago. I enjoy my Note 2 and keep my Nexus S as backup.
hi
I am looking for the source code of 4.1.B.0.431's application framework (source code of jar files in /system/framework ). I have got CM9's framework's source code but could not find Stock Rom's source.
Can someone help me in finding it please ?
U wont find it. Oem never give source for their rom, or else we would see sense running on xperia or touchwiz running on lg

Agree :highfive:
Well, I only need framework.jar's source code.
(Bytecode injection and java class decompiling would not work in all cases.
)
I am looking for it since I found out that Sony has released the source code of Xperia S kernel
I am sure that someone could find it

You can't find it. it's not public released. Android open source in OEM's meaning is releasing kernel, and maybe some libraries source code. You can't expect that big company, like Sony, can release something that makes their phones another than pure AOSP, that costed a lot of their employers effort.
I don't think that Sony has made huge changes (like changing classes names and methods) in the original framework. So, they won't loose that much in releasing the source code. Android isn't their own operating system. Anyway, if someone can get it that would be great.
Im interested to know how these guys (CyanogenMod, codeworkx) take the ASOP Jellybean and get it running on the i9300, ive seen (http://review.cyanogenmod.com) where they show the open/megred/abandonned status information.
Do they run a debugging app on the i9300 while testing for issues, how is it done?
Also, when samsung add their own features, like touch wiz, camera app + fm radio on top of ASOP, how do they go about (trying) porting it over to Jellybean to make it work? Is that samsung proprietary code? and does that require decompiling before trying to debug and port??
Any info/links to point me in the right direction is appreciated.
Cheers, Nic

The devs just download the AOSP/CM sources from their Android git/CM git and compile it in linux with device specific source files. These device files can be forked from a device like GNexus and modify it to support your phone. If the device files are already modified for your phone, then you can just clone the git repo and compile the Android/CM build.
They might run debugging app or they may not.. it depends on the dev's themselves.
Don't know how samsung does it. They make their own proprietary code.
This is just to give you a brief idea of how things get done here. If you wanna know more just Google. There are plenty of guides available on the internet, there are a lot of guides in xda too.
accidentally thanked u
The front page of XDA has a development section .

Hey guys,
eclipse is soooooo slow, so im trying to switch to intellij. My question is: how do i add the aosp or cm source to intellij?
I've tryed the same way like in eclipse but it doesn't work.
Thx in advance,
Kitty
what's intellij a device or what ..??
lol why not google it?
http://www.jetbrains.com/idea/
then you might be referring to adding or integrating the sdk right ???? or you want to test the whole soucre code on ide??
I want to add the source not the sdk. Like this for eclipse: http://source.android.com/source/using-eclipse.html
i dont have any idea abt i just build from source never integrated it into an ide ..
