hello. im new to android and i'm messing with openvpn and i need tun.ko. from what i understand, not just any tun.ko will work with a particular rom so i was wondering if anyone knows where i can obtain or at least make this file that would possibly work with the TPGB20110518 rom? thanks.
You should probably post in the author's thread, but I sse you probably can't post in the dev section yet (need 10 posts I think). Anyway, I looked at that ROM in the dev section and it's apparently running Di11igaf's kernel. I checked out his thread here:
http://forum.xda-developers.com/showthread.php?t=1070501
but he doesn't post any links to the kernel source.
With the source, it would be a simple matter of compiling in the module and adding it. I'd suggest you contact the author.
Pm the developer and he will respond asap
the issue was actually already resolved. did a bit of reading and apparently tun.ko file was built into cm so seeing as tpgb is based off of cm, it was built in as well. =)
Source is posted. Git is in my sig for the kernel

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As for the web pages, they are mostly outdated and don't include enough information, not to mention desire specific instructions.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.
Never mind, a further search pointed the source on the LG web site. But it is still appreciated if someone can post tun.ko because people were looking for it and I don't have the setup to do the compiling yet.
===============
I was trying to get tun.ko for ThiaiZO3D or other GB build. I searched the forum and found several people asked before in ThiaiZ's thread and ThiaiZ seemed to acknowledge to add TUN support long ago but it never appeared in ThiaiZ's kernel. I PM'ed ThiaiZ but he did not respond to me. So I am asking help here. In order to build tun.ko, do I need the original source to compile, or can I just grab some other source and set the correct CPU type and version header to just compile the module? If the original source is needed, where to find it? Or if someone had the source handy, can you post the tun.ko? Thanks for your help.

Hi mate, sorry if I didn't answer, I have really a lot of things to do right now, but would like to help as soon as I make my 4 ROM out there stable. 2/4 are already working stable, so soon we can join forces to port what you need in the kernel.

Thanks ThiaiZ! Actually trax11 has post tun/cifs modules long time ago. I should have done more homework before posting.

OK I'll probably get flamed by people like I did in the Development forum calling my simple question "STUPID"..... but could this be the link to the source code for the P6210?
https://opensource.samsung.com/index.jsp
We already knew where the source code was. The problem is that they have not provided the wifi drivers in the correct form, according to garyd9 the wifi drivers are only binary, so i think that means he won't be able to do much with those wifi drivers. Another problem is that the source has not been updated to work with the newest over the LA3 firmware samsung has provided according to garyd9. If we didn't have the source code, then garyd9 wouldn't have been able to build a custom kernel for our tablet. You can find his kernel here http://forum.xda-developers.com/showthread.php?t=1421466
Sorry if it sounds like if i'm being mean to you, but the source code links had already been posted a long time ago in the development section http://forum.xda-developers.com/showthread.php?t=1375911
First post in the Dev section but this seemed to be the place to talk about kernel compilation and module development.
I have twice now, and am working on my third kernel compilation for the purposes of custom module building for the TF700 and the TF201.
The question I have has to do with the compilation process. Every time I have gone through this with the downloadable Asus Kernel zip I run in to several issues. Either missing references in code or portions that won't compile at all. Is this normal for kernel compilations? I would have thought that it would be fully compilable out of the box ( so to speak). Is it ASUS or just android/Linux in general that works out this way?
Is there a better way to do it? Should I use some generic source with the same version numbers? The current source is just not working at all. I am using an Ubuntu distro. Have the cross compile tools etc... but it just fails. I have already resolved two missing definition references and it just keeps on failing in new places
Hopefully this question doesn't offend developers. I have moved from WinPhone to here and want to better my understanding of how this should all work but need to start with some basics before I can make a meaningful contribution.
Thanks.
P.S... I looked and didn't find a "Compiling android kernels for dummies" book

"Dummies" doesn't write a book on kernel dev. Too wrapped up in telling people how to download iTunes.....
Use your "Google". And when you find it, Google XDA University.
There, you will find steps for setting a build environment and kernel and cross arm.
Understand, all kernels are different, but a good place to start. Plus, you learn how to use Google. An added bonus.
Oh... and... as an extra bonus, I will move this to Q & A, as this post has no development work attached. :silly:

My question wasn't HOW to cross compile. I have done it.
My question is WHY are there so many errors that need correcting when compiling the ASUS downloadable kernels and if this is typical of the source from any device or just ASUS?

I had to fix exactly one pair of quotes vs. angle brackets somewhere in the RIL - get the patch pack from my kernel and apply the ril include fix. Then it should compile. If not, you are doing something wrong.
Can you post any links or names of everything ill need to get started on cross compiling a kernel for my tf700t I download the source and get my config.gz and am running a ubuntu distribution but if you could post a link to a tutorial that has detailed instructions that will work for the infinity that would be greatly appreciated thankyou

Step 1: Get a suitable ARM toolchain. I can't help you here with Ubuntu because I'm using Gentoo and their crossdev tool (http://www.gentoo.org/proj/en/base/embedded/handbook/?part=1).
Step 2: Cross-compiling the kernel works just as for native kernels (make menuconfig, make), but you have to pass parameters to each make, e.g. make ARCH="arm" CROSS_COMPILE="arm-gentoo-linux-gnueabi-" (or whatever your toolchain is called)
Step 3: For the TF700-specific blob stuff I have written a detailed tutorial here: http://forum.xda-developers.com/showpost.php?p=36925180&postcount=4
Ok, lately we have seen a lot of roms being posted that do not have kernel source links.
Be advised that XDA requires that you post kernel source when using non-stock kernels.
Stock Kernels
If your kernel is stock and not modified in any way, then you may post the link to the manufactures source (if available). If not, then state the kernel is stock.
If you have re-compiled the stock kernel, then you must have a link to your Git Hub with changes listed.
All others, including CM, AOKP, PA, etc
Link to your Git Hub, or which ever Git Hub or source you used. Along with changes. DO NOT just post a link to CM's site. Be specific which source you used.
All links to source must be links to a compilable kernel that works and matches what you have included in your rom. If you have "Cherry Picked" from other sources, please ensure you have their permission to do so, and, give credits when necessary.
Generally XDA will allow you 5 days maximum to post your kernel source. Please do not abuse this.
Failure to post kernel source will result in the ROM thread either "disapproved" or "Thread Closure" with all download links removed.
Most of you know the rules and GPL, so please abide by them.
Thank You for reading.
