Source code building a vanilla ROM

So talking to my buddy about all the "junk" loaded on the Samsung, he kept raving about how his old Nexus One was just the way I would like it. I would like to have a "plain" version of Android 2.1 on my phone. I have a coworker friend that's a Linux guru that's willing to help. Here's my questions.
Can I take take the Samsung released source for the hardware drivers and compile it with a stock Android 2.1 platform? I'm not asking for step by step. More of a 10,000 foot how to. Is that possible?
Can you leave the CSC and Modem info the same and just install a PDA ROM with Odin? Or would you be overwriting all of that info on the phone?
Thanks and if this has been answered before, please fill free to say "search is your friend" and give me the links...

I unfortunately haven't the answer but I'd like to add that I am curious about this too.

I'll second this and ask that if you do figure it out, please share with the community.

I think that vanilla Roms are a little further away in the future. First step in the process right now would be for someone to be able to compile a kernel from the Samsung released source code that works. Unfortunately the current Captivate kernel source code, when compiled, causes issues (voices garbled, lag when waking up the phone) that are not present in the stock precompiled kernel. These bugs are apparently not present in the other versions of the source code. Once these initial bugs are ironed out, we can truly start down the path of having custom fixes, and the devs can start to focus on bigger challenges, like making the vanilla Eclair or Froyo Roms to start working with our kernel. Good thing about this phone is that there are going to be so many versions of it, that parallel development is happening on multiple platforms. This will likely produce independent breakthroughs that could be theoretically ported between the platforms, but unfortunately it also slows down the development of each platform due to the quirks that have to be overcome. I hope that, in the future, we get to a place where all the source codes are merged into master repository that has all the necessary improvements and the ability to overcome individual platform quirks, so that the development can proceed more rapidly.

Check out this wiki from cyanogen:
http://wiki.cyanogenmod.com/index.php?title=Main_Page
On the bottom right you will see an advanced section that explains how to build from source code. (aosp)
Good luck!!! It's definitely not for me, not with kids and a full time job!

Good info. I haven't seen a post on people testing out the source code testing and their experience. Can you IM or point me to that?
Thanks!

Also for clarification, when you bought a Nexus One straight from Google for AT&T, was it considered "Vanilla"? Is the build on that phone just like someone downloaded the source for 2.1 and compiled it with the hardware drivers and that's it? I'm wondering what all comes on a "basic" Andriod ROM straight from the source.

Nexus One is as Vanilla as it comes. Just straight up Android! I don't think there is anything added to stock 2.1 or 2.2 on the Nexus.

Most of the kernel compiling struggles are documented here:

There are also people having success mixing Vibrant ROM on the Captivate with some GPS crash issues:

I am trying to follow those threads, and since I am not a developer, I can't personally contribute to the process. But it is interesting to me anyway.

I've seen these before. I thought they were just edited versions of ROM's sucked off a existing phone. Are these compiled from scratch?

The first two are attempts to recompile the kernel to put in the ext3/ext4 mimocan fix. The third one I believe is a script for boot logo animation hack to achieve the same thing.
I forgot to mention one more thread:

So we've got the source code with drivers and know which ones to use from the T959 for fixing the voice issue. We've got the stock kernel. What's left to creat a plain jane captivate?

I'm guessing not too much. There are somethings that would need to be edited such as handling the capacitive buttons. The i9000 roms handle buttons differently regardless of the kernel so, its apparently an OS level config.
I've been wanting to work on this but I've been neck deep in source code from work.
Here is a good how to: http://forum.xda-developers.com/showthread.php?t=704561

My point was that given the I9000 rom needs source level changes in order to work as expected(haptic feedback on certain buttons, etc) then running an AOSP build may require some source level changes as well. It may not be as simple as building and flashing.

I'm not sure how many actually remember the events relating to this earlier this year... But it was a mess.
Thor decided to start developing a ICS rom providing (presumably under apache2) the device/vender tree to the build. Just two little tidbits were, how to say, off with his approach.
a) The device tree included his kernel still without the source code (so now we have some apache2 code.. nice but not required, and its poisoned with a closed source kernel)
b) he provided links to the github repo (now deleted and/or hidden) on XDA via adfly.
After this was reported, XDA closed the thread, Thor took down the git repo and tried to pan this off to his greater followers (probably successfully) as XDA not even allowing him in when him to work here even when his code is "open".
--
While the source was open blazingwolf, ProTekk, randomblame (and some others?) managed to get the repo and clone it (or parts of it) into their own projects.. Mostly with little or no credit, and not always properly removing all traces of Thors kernel (either the main kernel was replaced with blazingwolfs open kernel, but a second copy of Thors kernel in the repo was left, or they just used thors kernel as it existed in the device tree).
In addition to this there was a recovery that used blazingwolf's kernel but otherwise was a nearly unmodified thor recovery binary (simply a hex edit to change the title, and thus hide the upstream source)
--
AOKP is now using the CM9 base for the device and vender trees, so everything including the CM9 T20 kernel is open source. However I its up to the AOKP team to re-post here at this point and not someone just wanting a mirror with their own unrelated donate link.
Some locked threads to remember in relationship to this:

Just to clear this up, roms are under Apache v2 license (which doesn't require source release) kernels are under GPL which does require source release.

sadly i do but the thread i linked is albeit messy with side stuff i made the assumption it was mod locked. after talking with the other people i have foudn out that the OP requested it be locked. i went and got the rom from AOKP website and as far as i can tell is Thor free and i run clockwork recovery and V8 ICS bootloader.
As for the motives for my request is i'd like to see more roms succeed for this tablet as it is "old" tech people are moving to the tegra 3 Tabs i am not ready to give up on my $567.87 less than year old purchase.

As do we all (want larger choices in roms).
But there-in lies the issue. We have an AOKP rom that has been through many hands, and at times, had some suspicious coding involved. Including getting closed on more than 1 occassion due to shady practices and non-GPL kernels. Might have been 3 seperate roms for all we know.
To post the rom now, would probably piss off quite a few people if enough credits were not given, even if the kernel proved to be legit. And even then, you would have several people claiming the rom was theirs and they were the original authors. That's the nature of these "KANG" roms and "MIUI" roms.
Well, we have polluted PaxChristo's welcome thread enough for now. I suggest we give it a rest, and probably open a new thread in the General Forum. I'll DL and install it, and see what's up with it. Post some results later.

I know this is not a Q&A thread but could I ask? Does this release of source kernel code mean, that Samsung finally released the source code for the dreaded mali GPU driver and the FM radio blobs that we so need to make CM roms fully functional and smooth?

No. Read following for explanation.
dhiru1602 said:
Blobs are userspace components which correspond to the HAL (Hardware Abstraction Layer). It is this layer which is responsible for communication between the kernel and the operating system. GPU kernel driver is opensource, but the GPU HAL is closed source. This is the case with all the devices, but on our device, much more components of the HAL are closed source like FIMC, FIMG, HWJPEG, TVOUT. Samsung doesn't release the source code for this components because it doesn't necessarily have to. Without the source code, we are forced to use the compiled binary which may or may not work properly. Since we are left without options, we often mess around with the Android framework, making dirty hacks to get them to work. We will not be able to futureproof our device with newer versions of Android unless we have the source code since making edits on compiled binaries is not possible and hence we have to wait for official releases so that we could get newer binaries (blobs). Here is the list of all the blobs that we use on our device. Having proprietary code is not uncommon, but Samsung doesn't release the source code for essential parts of the OS like Graphics subsystem, OMX and DSP, which makes things more complex provided there is no documentation for the SOC, nor they are wiling to help developers.

[KERNEL]Nexus 7 Compiled from Kernel.org Source

Hi All!
I have been trying to compile a Kernel for Android from Kernel.org Source. Avidly awaiting a Nexus 7 I got straight to work. I have created a zImage. I have been trying to document the process but rather than type it again I have been doing it here. If someone with a Nexus 7 wants to give this a go I would be very much grateful. This is an ongoing process. I have included the file and necessary instructions here...
It looks like I cant post external URL's .... YET! If you want to post here or PM Me I will send you the links.
If someone could test this for me it would be greatly appreciated.
Thanks

I'd like to help. How do you intend to test the kernel though? (since I'm not sure if it would work in Android, but of course you're probably more experienced than me)

Basically people flash it and then test it. People can provide their own benchmarks if they want. Against their previous Kernel versions etc. I have a sort of active thread on the Neowin Forums about this but I cant post links yet on XDA. I also got my VPS setup today to build and host the files.

Okay then, I can do that. I assume you can PM links?

You might be able to state the URL address in your post for your kernel. I'd test it and I guess others may also.

Hi All,
I have someone from Neowin who is going to post the links for me.
At the moment my guide and files are all disjointed I am trying to organize it better.

Great idea! I'll look around your thread @neowin.
What supposedly differences are there from the native android kernel and one compiled using the code from kernel.org?

Personally I just like playing with Bleeding Edge code. You would get all the latest features from source as well as bug fixes most end users wouldn't see. Performance is to be determined, Battery life and CPU performance etc. Its also quite a little Niche that I like been a part of if it all works and comes off.

The kernel you're compiling most likely won't work if you don't even have the machine definitions nor the drivers for your nexus (seeing that you have taken the source directly from kernel.org)
The best of testing a new version would be to backport it but doing so takes an incredible amount of time and considerable skills.

I have used the Prebuilt ToolChain from git and also the defconfig to build the kernel from Google. I have created a boot.img this should make it easier. I am just waiting a Nexus 7 myself to test this anyway.

You need to have proper board files, proper drivers (device-specific ones) and tons more. I don't think it will work without those. Then chances are it's not going to compile properly; it will throw tons of errors. After you get it to compile, you have to get it to boot. After you get it to boot, you have to get it fully-functional (not necessary if this is a test kernel). So unless you have gone through it all, I don't think it'll work.
BUT I may be wrong.

It compiles no problem, That's what I am wanting people to test :good:

I have done some more merging from latest Mainline and Flo Kernel from Google. Its building as we speak. Time to head to Tesco.
Hopefully what I have done will get rid of a compile time error I was having.
Has anyone got the ones I made previous to boot. I have my Nexus 7 on the way as of today so I will be testing it on my own sooooon!! :good:

A bit more easy to remember. There are some test builds and experimental stuff on there too. I might do requests if anyone wants me to make a build for their device let me know. Rather than the Nexus 7 2013. I only did that because thats the device I am getting

We will see, it is very hard to port when kernel is not given. There are people working on it and doing a very good job!
Sadly, the complete kernel (custom kernel with drivers) was leaked for a short period and a few devs have it.. but they are afraid to use or publish it because they don't want to be sued.

Sued? The ones to be sued are mediatek and/or xiaomi for not complying gpl license

At least someone has it.. I am not so sure on how many have it. Don't be too excited yet, we might not get it (soon). The source can not just be published to the public, the one who does will face some problems.. (see what happened to incomplete source).

May i ask what happened?. And i know is not that easy, what i meant is that he (or they) could make a nice ROM build with that source, maybe as an anonymus guy or something like that, is not necesary to publish full source code. Our another hope is wait for MTK to release it , but it wont be soon, even could never happen

We can build roms ourselfs, just need proper kernel. Just let me say that much: I have a reliable source that told me someone has it. I don't think (anymore) it was leaked to the public ever, all kernel leaked on git were incomplete.

All kernel sources I've seen for X10 are not for our device. Another thing is the AOSP sources are very buggy and unfinished.
I finally made progress on my AOSP 5.1 and fixed the slow app launch (maybe you've seen one youtube video posted here - this is my build).
Unfortunately I don't have kernel source for Redmi Note 2 and it is impossible to build a custom kernel, so I'm trying to finish the ROM and will use prebuilt kernel.
If you think it is easy as porting, then you're wrong. Compiling something from source and fixing all bugs is completely different animal.
CM 12.1 also booted, but a lot of work needs to be done there too.

Check the date and please stop posting same thing again and again. This is the original broken half source that was leaked over 2 months ago now.

What is time to wake? On miui time is long :/ On our last phone (A820) time to wake is much better.
How aboute "tap to wake"? What is result on antutu? When you publish rom?

AOSP boots up and works faster than MIUI and also has much much better ram management, although it would be good if we could make a custom kernel.
Tap to wake normally needs to be supported in kernel, so the answer is "no".
Antutu score is irrelevant, but normally I get about 48K with the basic model. I've seen higher, seen lower.
It also depends on kernel.
Don't forget that for A820 I have a custom optimized kernel.

Hello
When you share rom? How to progress?

Known XDA rule, don't ask for ETA He'll tell us when ready

It will be shared when it is done.. Ussd/BT working but camera still doesnt
