T-mobile Prism II released the kernel source
https://github.com/Prism2/HUAWEI-U8686-Open-Source-U8686-JellyBean-kernel-3.4.0-
That is the link for the source kernel i found with a simple search.
This phone is so close to having a custom rom. Rooted, bootloader unlocked and CWM_recovery has already been made possible on this forum.
So my question is... Where would add the line CONFIG_SWAP=y in that open source kernel.
Is that all that needs to be done to this kernel to enable swap?
I'm sure it simple anyone know?

Its a little more complex
Guide for Jellybean can be found HERE
Thanks a lot for that link.
I'm very inexperienced with android and that doesnt look easy. Anyone interested in helping me with this?

Hi there,
Now, I understand that there's a thread or two and a few web pages directed at compiling Android and its kernel from source.
However, the thread in question is months old, and didn't fully explain the process.
As for the web pages, they are mostly outdated and don't include enough information, not to mention desire specific instructions.
I think that, properly explained, building Android shouldn't be daunting, and everyone should be able to attempt it, if they wanted to.
So, I hope to compose a comprehensive guide on how to do just that.
The problem is that I myself have not been able to put enough instructions together to be able to complete a build. And there is no point digging up old threads.
So, If anyone who knows the ropes (that is, compiling android and a kernel from source) would be willing to lead the way, I'd happily turn it into an easy to understand guide.
Josh.

I followed this guide here and successfully compiled a modified HTC Kernel and I had very little Linux and Android experience.
Obviously instead of cloning the Cyanogen git, you just use the gits you wish to compile

Thanks for the link
Though i don't fully understand the whole 'git' thing. Where do i find them? And how to i know which ones are the ones i want to use?
Josh
EDIT: Also, how do you 'edit' the kernel (i imagine it is somewhat like make menuconfig?). Also:
- Are these sense kernels?
- How do you add modules like OC and UV?

A git is a repository for source code, developers upload their source code there and can commit changes. The commit can allow descriptions of what was changed and also details the files changed.
The git system allows other people to add to the source if they have permission, or allows others to read the changes and download the source code.
Git links are usually posted by people who release software, as Android is GPL licensed so people have to release their source code if they're distributing their work.
Editing the kernel, take a look into the git and the commits and it will show you which files were changed and how exactly they were changed. That will give you the best understanding.
UV/OC is done by changing the acpu table in the architectures files and changing the minimum/maximum voltage figures in the board_bravo.c file.
The Cyanogen kernels are not Sense kernels no, it's a modified Google Kernel.
Thanks for the explanation. I followed the guide and built the rom, and it works (always a plus )
Now, the next thing is the kernel. How do I build a kernel with the CM tweaks integrated? I understand that all i would be doing is rebuilding the same one that is already installed, but im doing it to learn.
So, if i synced the GIT, does that include the CyanogenMOD kernel source? If it does, where is it and how do i rebuild it. If not, where do i find it?
Thanks,
Josh.
Hi there!
I want to compile CM 10.1 for my phone, but stucked with device tree and i don't know what tree to choose for this.
Phone mentioned in the subject is Qumo brending of chinese i9220 PAD 5" MT6575 (e1809c_v75) Android 4.0.3
Great thanks if anyone can help.
PS. Sorry for my English.

I dont think there is one for that as that is not an official version of Android. Very few China based Android phones are supported by AOSP. You may have to start it yourself if you want it. The first thing you will need to do is have the OEM post the kernel source code for the device. This will be your biggest challenge. As most China OEM dont respect the GPL laws

Ok
What if there is no source of kernel? Can I use compiled kernel (3.0.13) from current firmware (4.0.3) or this is impossible?

Without kernel source your kinda out of luck. No that kernel will not work on AOSP as that 4.0.3 is not an official android version. It is a hacked together version. Your best bet would be to sell it and get something that is not a knock off.

Got to write to the OEM. Only they will be able to release the kernel source. Good luck. Dont hold on to hope though. They are not forced to post kernel source like everyone else.

Don't you know is it real to compile with another kernel for same CPU MT6575?
Found some links to kernel sources for other phones - seems to be working for different devices.
Hey guys,may I know "In order to make a build for your device, you will need a suitably device configuration. Often these are included within the main source download, or are obtained through a method documented by the developers of the ROM." <<<<<where can I get this?
Should be the source code, i guess.

Kernel source code?
I think so.
Where can I find proprietary binaries?
Kernel Source code can be found at www.htcdev.com
After it is released.

And the binaries are located in the source code?I'm asking all this questions because I'm in the midst of developing.And to further understand so that it would be easier for me.
I'm no kernel dev, so i can't answer more than this.
It's ok.
Hi guys. 2 months ago I've came into Android World deeper than before and now I'm very fascinated. I downloaded linux, all the necessary files to compile a rom but I still don't understand some things.
My device is Redmi Note 2 and I use stock MIUI 7. As we all know mtk and/or xiaomi haven't released kernel sources (6795) so developers have to think hard how to make a rom. And there are my questions. Does kernel source is really necessary? What if I compile rom successfully and then port boot.img from stock? Will it work? However developers made some roms based on LP for this device. And I read that I need device tree and vendor, which doesnt exist for redmi note 2 or I still can't use github.
Second question which I have is: does compiling for 64 bit CPU differ from compiling for 32 bit CPU (like 6592)? If yes, could you give me some tips?
Ohh I think you can understand what I wrote
Thanks in advance and please dont blame me for silly questions
If you are looking to compile roms then you picked the wrong device to do it. They are the worst with kernel source. You can't completely compile a rom but use a patch system that does most of the work.
Yes it is different. There are some Tuts around but they are few as most don't use that type of chip.
If you really want to learn to develop then I would suggest getting a different device. One that respects the copyright and gpl laws.

Thank you for your advices. I have HTC desire 310 and I found the kernel sources. I know what I'll do in my free time

To compile a rom u need kernel source, device tree and proprietary, bye
My device is Nokia 3 TA 1032 running Android Pie rooted using Magisk and with TWRP custom recovery with kernel version 3.18.119+ ....
Is there a custom Kernel available for this device which is 3.19 or above.?.?.
If so ...can anyone provide me the link please.?.?.
And if not...does anyone know about porting/compiling kernel for this device.?.?.
please...i need some help....

I dont' know if there's a custom kernel for this device. But you can download the source code form here https://www.nokia.com/phones/en_int/opensource to compile it and add features by yourself.

sir there seems to be multiple files...which one should i download.?.?. I am really new to this...
and I will be very grateful if you can point to any tutorials or blog posts on how to modify kernels coz i cant seem to find any...

To compile a kernel from source you can follow this tutorial.
https://forum.xda-developers.com/android/software/ultimate-guide-compile-android-kernel-t2871276
There are more threads, this is an example.
The build number in your screenshot (5_180) tells the number of the kernel version you need to download (i want think so ), in this case is the Nokia3_V5.180.tar.bz2 file.

With having a linux environment you can build a kernel from source reading the guides. Adding features is more difficult because the main reason: this device has mediatek SoC.
