Hi guys..
I did a compare on the source code from the code Samsung released (so eclair) and the vanilla linux kernel..
http://pastebin.com/QhEJ0eaU
Anyone who wants to use this information to do something good with, is more than welcome to.
Can I use the stock kernel (Froyo) and the binary drivers that comes with the stock and use the aosp source code and build higher version of the platform (gingerbread, icecream ) as and when they are available?
Why do the kernel needs a change when upgrading from one version of android to another, the hardware doesn't change anyway.

OKAY LET´S GO MAN
you can´t port a kernel from froyo to ginger for example because the kernels are created with diferents codes...
if you want to create a custom kernel from a stock kernel you needs the "privative drivers" and the source code for to do this... gingerbread has another source code than ice cream (still closed source)
the same thing happens with AOSP (cyanogenmod for example) but they uses a pure LINUX code for to create a custom kernel..
AOSP also needs the source code of the android version for that are creating the kernel.
and the kernel need to be changued between android versions because are not compiled of equal way.
ext4, task admin... and H/W don´t works equal between android versions
Firstly,apologies if this is not the right section.
We all know that android source code is available.So my question is how can I build the source code and install on any device?For example if I have an old device for which updates are not available.Can we just flash it with any android stock rom?Not talking about custom rom.
Can we take the source from github and just build and flash on our device?Because android is hardware independent? Like we can install ubuntu on any system?
Hi, may I ask somebody experienced with ROM building, if it is possible to build fully functional and stable build from AOSP sources if i have kernel sources for my device from vendor?

Hi, yes. I've compiled lollipop nexus4 from aosp in ubuntu 14.04.1 x64 in vmware.
I've downloaded the source, included the proprietary files, and compiled android, compiled with make and make otapackage to generate the zip.
After that i've rooted the device, installed twrp.
Finally, i've downloaded the source kernel and compiled to generate the .img. I've flashed this to the device with fastboot, and
yeeeeeeh perfect!!!
obviously, after this, i've downloaded the gapps and installed.
But, which version would you compile? And which device? All the sources are available and open source?
i wana make AOSP build for Huawei Ascend G6, I have only kernel sources from vendor... I suppose that kernel will work with any version of android or not?

Ok, you have the sources, very good.
mmm, i'm not sure that every kernel + android combinations work perfectly together.
For example, on my nexus4 i've kernel 3.4 and lollipop. Now, if android lollipop requires some modules/functionalities/"other magic stuff" to work properly from the kernel, and you install kernel 2.x.x without this feature, probably you'll have problems.
I mean, i'm not sure, but is only a logic hypothesis.
You can solve this problem using the latest official version of android from Huawei and your compiled kernel from Huawei sources. If this works, try to update android to another version with a custom rom. It works? Perfect!, It not works? Damn, restore the backup and use another older android version
To build android/kernel you must transform into a researcher :laugh:
I have written a linux kernel module for my Pixel2, and compile it under AOSP source: kernel/msm.git android-msm-wahoo-4.4-oreo-dr1
But when I insmod my module, dmesg reports "disagrees about version of symbol module_layout".
Google told me that the kernel source version I used to compile my kernel module is not corresponding to the kernel source version used to building the official Pixel2 kernel.
Where can I find the kernel source version/branch of AOSP used to build the official Pixel2 kernel?
https://android.googlesource.com/device/google/wahoo-kernel/
Thanks, but this link only has some binaries used for pixel device.
I want to have the kernel source location and its branch and version used to build the pixel 2 official kernel.
