Hi,
after many failed attempts, I turn to you for something that is normally easy.
I want to compile a kernel for my Hero.
I am currently on this ROM: VillainROM 3.0 BETA
but in the context of a project (serial communication with the phone), i need a specific kernel.
If someone could edit the .config file with these details:
CONFIG_HTC_HEADSET
This entire line should be replaced with the following:
# CONFIG_HTC_HEADSET is not set
CONFIG_MSM_SERIAL_DEBUGGER
CONFIG_MSM_SERIAL_DEBUGGER_CONSOLE
and replace them with:
# CONFIG_MSM_SERIAL_DEBUGGER is not set
# CONFIG_MSM_SERIAL_DEBUGGER_CONSOLE is not set
compile the kernel and repost it would be great.
Thank you very to everyone, this forum is very interesting.

Sorry - I did answer you in the thread yesterday.
Have you attempted to compile it for yourself? If so, what was the outcome?
you won't be able to compile a kernel for a 2.1 rom since the sources aren't released yet. if you want to compile your own kernel you are stuck with 1.5 roms...
btw, where is your problem with compiling the kernel? i can try to do it later when i'm home, but again, we have only the 2.6.27 sources, which won't work for eclair roms (including villain).

Sorry i didn't see it.
Yes I tried but I think without the right items.
I'm not a pro in kernel and ROM.
Already, it is possible to use the Vilain ROM with a modified kernel?
If yes, anyone could build it with the above specifications?
Thank you

I am guessing he means it is a lot of work and will need a dev phone to do it
no, actually a NEW phone. i am a bit frustrated with my hero right now, it has come down to noob talk in these forums. people ask for help "help my phone don't work", you ask them "why exactly, what does it say and what did you do before" and they answer "my phone won't work anymore, please help me". if you analyze this conversation it was like this:
a: i need a custom kernel for 2.1 and if i try myself it doesn't work.
b: you can't have one, the sources aren't out yet. what are your problems?
a: can someone make a custom kernel for 2.1? i tried but it didn't work.
going to ebay looking for a nexus, again...
now go and bash me for trying to help, i deserve it. definitely.
Hi y'all.
I am new to development and would like to get started with some small kernel modifications.Seeing the fact that I am a speed freak(even if I cannot notice improvements,just knowing that my CPU runs at higher values feels gooooooood!) I decided to start from what I miss from some roms(like LeeDroid Mod),the option to overclock.
I searched inside my system files and found in /sys/devices/system/cpu/cpu0/cpufreq a file called cpuinfo_max_freq which contains the value 998000(the maximum frequency) and scaling_max_freq which also contains the value 998000.I tried changing these values to 1382000(too much,I know...),saved the file,but when I opened it again it was back to 998000.
I was doing all this with ASTRO,but then it occured to me that I would need Root Explorer.However Root Explorer is a paid app and currently no paid apps are available here(I live in Greece).
So now I am thinking of reinstalling the rom but with these values changed from my pc,inside the .zip file.I don't know if that'll work though,I'd think it'd be much more complex,not just change two values and job done.
With that in mind,I'd like to ask if doing something like that would do the trick or if I need to recompile the kernel.If that's the case,how do I recompile it?
Please bear in mind that I am a total newbie and these are my first steps into developing.Until now I had only been installing what other people had already made.I decided to start learning so someday I will be able to contribute to the community.So please don't be harsh with me or treat me like I'm some stupid guy.
And I put the thread in development because I believe it fits here and maybe some other people learn from things said here.If the mods decide it doesn't fit here,then please move it to general or Q&A.
I sincerely hope some of the great minds here help me.I acknowledge that most of you here aren't random guys,but developers with talent and many contributions to the community,that's why I ask here.Thanks in advance!
Don´t know if you know...if... forget the post
In non Sense Roms the source is out..so you can overclock....HTC have not released the source yet..so we don´t can overclock
just for info...with kind regards..Alex

They haven't released the source yet?That I didn't know...Stupid guys that they are,they're making our lives more difficult!
Anyway,the point of the thread isn't only how I can overclock my device,but to learn.If the source was available,would that be the way?
Thanks Alex-V!
Edit:BTW,does anyone have any idea when they will release the source code?I believe that it won't be long...

I am in need of a kernel with loop enabled. I am in the newest OTA, if one doesn't exist I could use some help compiling one from the newest source, I have everything I need to do it on my Linux machine I am stuck trying to find which makefile to edit and where the .config file containing CONFIG_DEV_BLK_LOOP is located.
If it matters at all I would much rather compile my own kernel so I can learn something new.
Thanks for any help guys!

Really!? I am not lazy or dumb, I have gone through a lot of kernel threads and it is not stated wether or not loop is enabled, all I am looking for is a kernel close to stock with loop enabled, come on guys I know someone here knows of one, if not is ANYONE willing to work with me while I learn to make one?

LOL. I'm on the more technical side, program for a living and have compiled a share of Linux kernels in my life, and I'm not quite sure what you are referring to. Sadly most of the sharper devs pretty much handle these forums in a one-way manner, they put out stuff, but they rarely read other people's posts. There are plenty of people that like to help out, but most of those folks aren't going to know anything about compilation.
The makefile you need to edit is in the root of the kernel source. The very first one that you see.
I am referring to loop devices support, this enables me to boot ubuntu on my Evo, it is one line of code that needs to be un-commented and changed to "CONFIG_DEV_BLK_LOOP=y
I am just lost,I was following this tut here http://htcevohacks.com/htc-evo-hacks/how-to-build-your-own-htc-evo-4g-android-kernel/
but the directions seriously slack off from step 11 onward, any ideas?
Do you by chance want to install Ubuntu on your phone? I think I saw something pertaining to that in some instructions I browsed over a while back.
lithid-cm said:
Grab the latest HTC source code:
edit the makefile:
Code:
CONFIG_DEV_BLK_LOOP=y
Then compile the kernel. There are plenty of how tos for kernel compiling. Let me know if you need more direction.

I have all the files I need, I was following the tut at htcevohacks.com but the instructions seriously slack off & there are numerous makefiles in multiple folders on top of that I can't seem to find what file contains the line config_dev_blk_loop, could you point me to a more complete walk-through please, oh and I am on the latest OTA with the newest kernel and radios.
Bump for desperation,chewed up almost 3 days of my time...

Ok, well I guess I am gonna just have to PM each Dev individually about each individual kernel, damn all I need is a how-to or tut on kernel compiling (which the search function apparently can't find) or someone that knows of a 2.2 kernel with loop devices enabled. Oh well.
I'm pretty sure netarchy kernels are loop back enabled. Ask around there maybe.

YAAY! LMFAO, I will ask there, sorry I'm excited but I have been trying to get this working for a while; I would much rather learn to build it myself but I will take what I can get for now.
IF ANYONE knows where there is an in-depth tutorial on how to compile a kernel from the newest source I would be extremely appreciative, THANKS
Did you ever find or get your Complie to work? I tried for a while to compile the stock Kernel, then gave up. I took a stab in the dark and flashed a stable netarchy kernel. unfortunatly that Kernel didn't have Loop devices enabled (Pulled Config file and Unzipped it) I like the Kernel I am running but need to find a way to get ubuntu running.
Netarchy does have loop enabled, I am running Netarchy ___(will find which version later can't remember) but yeah I am running Lakia Linux
now(network security testing, think Backtrack 3) as well as another new Linux image from a guy here, anyways I think you need Netarchy universal cfs havs less no sbc 4.2.2

Hi everybody,
I have made a free application to install any kernel on your SGS very easily.
The idea is that there is a website where kernel are uploaded with a script and an application to:
- search
- download
- install it on your phone.
The application and the website are not limited to install kernell but I think it is a good way to try it.It can execute any script in the android shell.
So I have made some script for some kernel, there are so much that I have not the time to make one for each of them.
To make a script is very easy, I have attached an example of one I have uploaded on the website. If you need to attach a file, put it in a zip and upload both (the script and the zip) through the upload form on the website,
The address of the website is:
http://www.2borange.com/
A general thread on XDA (not dedicated to kernel on SGS) about the application:
http://forum.xda-developers.com/showthread.php?p=14875954#post14875954
You need to create an account to upload but it is not mandatory to just search, download and install a kernel.
Please keep me informed if everything work or not. I have only test it on my phone.
For the author of the kernels: I am sorry to have not yet informed you of the sharing of your great work, I will do it for sure when I will have done enough test to offer you an interesting way to share your work.
For the user: if you have time, don't hesitate to upload some scripts, it is free and easy to do...
Thank you for everything,
Michael

This allows you to actually find a kernel, download it and flash it as well. The Kernel Flasher is just for kernels already on your sd card.

Thank you for your message.
I did not know about this application. I have read the description and I can tell you the purpose of mine is totally different.
I have understood that Nedar application is to install a Kernel that you have already downloaded and copy on your SDCARD.
The purpose of my application is to download automatically a script and a zip file, and execute the script.
So there are 2 main differences between these two applications:
- my application get files you need directly from the cloud (Internet), so it is like a deposit of files
- my application is not limited to kernel installation, it is just a usefull example to show people how it works, but it can do more, really lot more tasks.
However, because the application of Nedar is dedicated to one particular task, it has option I have not yet implemented in mine. By example, I have not yet construct a script to backup the kernel in an update.zip file, which could be very usefull.
So they are really very different. I hope I will be able to construct more script, but may be the biggest difference with any dedicated application is that anyone can participate to my project without any knowledge in Java programation.
You just have to know a little bit about shell to be able to share your work with others.
THAT IS THE REAL PURPOSE OF THIS APPLICATION : SHARING!
Amazing concept!
Thumbs up for the foresight for such a nice project. If enough effort is put I can see in next couple of months, the whole, ROM, Kernel, Modem flashing automated.
Right from finding the correct software till installing them and may be some debugging and fault finding as well!
Will definitely donate in case the project takes off the way it should!
Great work Snoopy!
Loving the concept of this!
As omzworld was saying, if this grew into a script that could automatically install your ROM/kernel/modem etc. that would be awesome, especially for people who are new to flashing.
Now, here's another suggestion that may or may not have been thought about already..
Is there any way to make the app look at your phone and use that as a basis for roms, kernels etc. ? If that was possible, anyone and everyone would be using your app to flash because they would know that bricking their phones would be almost impossible.

Thank you for your interest.
The thing I need now is not money, donation,etc... but report of test and ideas of improvment.
By the way, I only have a samsung phone, and I am wondering if there are possibilities to install kernel in other phone only by using the shell, have you an idea ?
Second question: have you an idea how to proceed to install an entire ROM through the shell ? I suppose the phone has to be rebooted before installation begin and lauche in a recovery mode, but how to make it automatic like in ROM Manager?
Thank you for your help!

Hey snoopy33, why do you have not yet updated this page?
I thought of developing a kernel so that i can use it with my CM11 that im going to port shortly. I thought I'll compile the stock kernel from source itself. I use android pre-built tool chain (arm-eabi-4.6)
I get a lot of compiler errors on stock kernel without any modifications itself...
Do i need to change my tool chain?
Sent from my One V using XDA Free mobile app
I never tried to build the stock kernel, but I think they did it with the android 4.0 toolchain.
To run CM, you need a CM-Kernel. You have to port things from the stock or a custom kernel (like Hellboy by maxwen) to the cm11 kernel.
Try to use rastomanchiks kernel sources (https://github.com/rastomanchik/android_kernel_htc_primou). This kernel is mostly working, stable and has a good battery life now.
I'd also like to build cm11, but my download speed is to slow to download the sources.
Exactly. Even my download speed is slow. And i have a cap also. After 8GB, my download speed drastically decreases. It takes ages to sync the sources...

Cm needs many features which aren't included in the stock kernel and also you should get ION memory allocator working.

I can't help you with porting, because all the porting work was done by rastomanchik and I chatted with him. You'd have to ask him about this, but he wasn't online the last weeks and can't speak english without google translator.

Actually I insist on porting myself so that I can learn building properly.
Actually these things are also interesting.. fixing bugs and all...
Have series of exams till May end. I cant build properly until then. I thought why not learn something..
Where did you learn about building and other stuff. Also I want to build the device tree on my own.
If you could specify some sources to learn, that would be grateful!

This is exactly the same point of view I had when I started some months ago
Sadly, there isn't much documentation about own device trees and own kernels out there.
There also is no reference device tree, so every dev does it in his own way. I'm always trying to have a clean, easy device tree and use the CM ones as a reference.
You can find some tutorials about building cm, but only with downloading a ready-to-use device config and kernel.
I just played around with it one or two weeks and learned the most.
If you have enough time, please at least try to get into this stuff, maybe we can get cm12 running.
You can reach me on irc in the channel #hov on freenode.

I have sufficient time only after May. Till then I'll have to do some research and learn the basics.
I saw on the CM wiki page, it says you can run a prebuilt kernel also... So would it work if we could tweak the stock kernel a bit?
And how do I apply patches to the kernel?

Yes you can use a prebuilt kernel, but it will only work if the kernel supports you cm version.
You apply patches to a kernel by changing files or directories in the kernel. For example you can use another fs module (maybe with more functions) by copy and pasting the folder for the module from another kernel. The problem is, the new module may require some functions your kernel does not have so it won't compile.
