Hi All,
Running rooted Hero with Modaco 2.5.1 rom ( thanks Paul )
Was hoping someone could ( simplistically ) answer a few question for me.
As I understand it - one of the things holding back development of Hero ROMS is that HTC haven't released the kernel for the Hero.
1) What exactly IS the kernel in the greater scheme of things?
2) When are HTC likely to release it?
3) When it is released, what new things will it allow developers to do?
4) Anything else relevant to it worth knowing?
TIA
Look at these:
1. The kernel is the Operating System for the phone, it runs everything.
2. That is the magic question...
3. It'll allow more development in terms of mods. we'll be able to change alot more and get more out of the phones.
I'm sure others will have more detailed explanations.
Regarding question 2:
I've gotten response from HTC support the other day that the release is planned but no sure date could be given.
Date: 5th of October
My question:
Hello there, I realize that this might not be the normal kind of request you guys get, but here goes. This is probably not your average request and might require escalation. I was wondering when the source code for the Hero kernel was gonna be available at developer.htc.com?

Answer:
Hello
This is quite a normal question we get here at HTC. The source code is something that will becoming soon. We have had contact with those far higher than my self or are planning on adding the source code as soon as possible. I have not been given a time scale but bases on the code for the two other handsets i should expect it in the next couple of weeks.
Hope this helps.

So, educated guess would be around the release of the Hero in the US.
Some if I have this right -
The kernel is the basic underlying OS of the phone, and a ROM sits on top of this end gives us the end user experience ( and Sense UI is within the ROM ).
Am I right in thinking the kernel is linux based?
And a big magic question - when the kernel is released, will people be able to modify it and get the bluetooth working properly?
Sorry if it's a bit basic - but interesting to me....
The Kernel is not the OS (As most people understand an OS to be) (OS meaning Operating System)
It's at the core of the OS but is not the OS. You can keep the same build of an OS but update the kernel and vica versa. It is (put simply) what converts the hardware calls from the OS into something the hardware understands.
So (using current issues as explanation) The OS tries to load the GPS and the kernel isn't configured with the right settings the GPS won't load. Similarly if you try and use the trackball and it's not setup in the kernel then it won't do anything.
The OS will still work fine with other things but until the kernel has the right settings put into it it just won't see the parts of the phone it's not set up to.
Here is a technical description of a Kernel.
http://www.linfo.org/kernel.html
I'm sure I've just made it as clear as dishwater but if not I hope it's helped.

Not exactly. To add to what akirainblack has said already...ROM stands for Read Only Memory. In this context it is a bit different as it is the complete package that makes up the Kernel, the OS and anything that is pre-installed to the phone. When you run the RUU (Rom Update Utilitiy) on your PC is completely refreshes the system software in your phone - Kernel, OS and any pre-installed apps - just as if you had bought it from the shop like that.

Yes.
Hmmm...
simple question... when the kernel is available... would we be able to get a white taskbar on the Hero?

When the kernel source is available, we should be able to rebuild Android completely from the source code repositories and do practically whatever you want.

In theory, yes. In practice, the situation is a little more complicated, but at the very least I'd imagine it would be possible to get BlueX, or something like it, working on rooted Heros fairly quickly.

Given that this is a Linux kernel, aren't HTC required by the GPL to make the source available to all Hero owners?
This is covering the same ground, but is another way to look at things regarding the kernel and the OS. The kernel abstracts the specifics of the hardware from the Android system. For example, when the Android system requests that the bluetooth hardware be enabled, the kernel can translate that request so that it works with the particular hardware of the phone - as the bluetooth hardware of the Magic may be different from the bluetooth hardware of the Hero. So the kernel, is an interface that translates and Android call to the specific hardware level controls necessary. The kernel sits between the hardware and the Android system.
It also means that releasing the kernel will not allow us to make changes to the Hero Android user interfaces. If we want to change colours, icons and so on in the Hero ROM, we would need the source code for their "tweaked" Android and maybe to some degree their TouchFlo software. I doubt they would give that away. It would allows us however, to tweak the kernel, or transplant the driver code for specific hardware pieces in the Hero, to a newer version kernel.
I understand that the release of the hero kernel, could help me with my cause (getting 1.5/1.6 'clean' android on my hero without any htc apps/front ends).
Somebody suggested contacting HTC and asking for it to be released.
I have a few questions regarding that:
1) Has this happened before? That HTC released an android kernel?
2) Did this happen after the request?
3) Who should we contact to get it? (which HTC division)
4) Is there a possibility that they don't want to release it, because it would allow people to copy parts of the proprietary interface?

The HTC Sense UI won't be included in the kernel source.
They dont have to release the source of them.
New question
Is it possible to create a new donut kernel (2.6.29) with the changes they made to the 1.5 kernel (2.6.27)?
Looks like they send you the hole kernel, not just some patches and new drivers...

So this means that we could compile or 'cook' a working vanilla android 1.5 for the HTC hero, with everything working fully?
HTC HAS to release the kernel source as required under the GPL license that the kernel was released under. It is indeed a linux kernel and it contains the necessary parts to work the hardware along with extra drivers and modules (stupid monolithic kernels).
Here's what I don't get (and hopefully somebody will clarify this for me). Why hasn't anybody tried building android with the current kernel available? Android has the ability to be built around a pre-compiled kernel (it does this if you do a straight make right after repo sync with the pre-compiled dream kernel). You'd only need to re-build the wlan.ko module for the new kernel and the gps module would be compiled against the specified kernel, so it should work.
If I had Hero, I'd test it (if you want to trade your Hero for my G1, hit me up ), but there's no reason it shouldn't work.
Up to now, I've only seen ports, and those are hard to make work because of the pre-compiled files, so that leads to loads of file-swapping and finger-crossing, but an AOSP make should still work. Anybody wanna try it (or post me a hero kernel and I'll compile you a stock donut build to test).

Hi, thank you for this information. You make it sound like it's possible
I tried searching for the Hero Kernel, but I could only find this:
http://developer.htc.com/
The hero is not listed (maybe it shares a lot with the magic kernel?).
edit: this post dating from september 10 stated that HTC would "release the kernel source soon".
This was more than a month ago though..
edit2: calling HTC Netherlands right now..
edit3: after explainig the need for the kernel, I've been on hold for 10 minutes now..
edit4: more than 18 minutes now
edit5: after 26 minutes I hang up
Well I have a Hero running Modaco 2.2. I could post this kernel (where?) Or it surely could be extracted from one of the ROMs available on this very site

I could be wrong, but I believe there is a difference between the 'kernel', and the 'kernel source'. The second one is needed when you want to compile the kernel.
Speaking as one who has compiled kernels in the past there are three components required here:
The kernel source- this is typically available from http://kernel.org/ If HTC have made any changes to the source of the kernel itself then these should be apparent in their distribution of the kernel source
The relevant configuration file '.config' which should accompany their distribution of the kernel source and permit you to compile any other kernel as a drop in replacement.
Source code and makefiles for any custom kernel modules ('drivers' in windows terminology) In Linux these have to be compiled together with the kernel.
To use a cookery analogy:
The kernel source is the raw ingredients. It can be set up for anything from a supercomputer to a DVD player depending on how you use it. The kernel config is the method which will allow you to bake the type of cake you intend. The modules sources are any of HTC’s own custom ingredients required for everything to work. THe kernel is the finished cake which you eat.
Hi, I would put some linux binaries (arm architecture ?) on my phone to support the ADB SHELL activity, to enlarge the busybox capabilities.
For instance, I mean stuff like a bash shell, a complete gtar for backups (the busybox one isn't adeguate), md5deep, and so on.
Could you please give any hint to do that ?
Thanks

The first post here: http://forum.xda-developers.com/showthread.php?t=777380 contains a link that actually contains a complete binary arm cross compiler. If you use linux (works with most 32 bit distros, needs multilib on 64 bit distros) you can use that to cross compile your code to arm.
Many thanks for your answer.
I'd static link libraries, I guess...
Btw could I also use normal binaries for 32bit arm architecture ? (i.e. debian distro...)
You can also use some of the binaries of the CyanogenMod for Desire (or any other phone) and use these (bash, nano) http://androidforums.com/evo-4g-all...shell-nano-tab-completion-color-over-ssh.html

How does I set up teh linux?
1- you dont know anything about linux. go ubuntu. we will tweak it after that. version 10.xxx (cant remember exactly).
2- you've used linux before and feel comfortable when thinking about it. go ubuntu/fedora.
3- no worries. you can troubleshoot alone when leenucks acts funny, you su everyday. go arch linux.
bottom line, it all comes to a few package versions.
make, python2, git, jdk, maybe a few others, need old versions. even in ubuntu, if you would like to start from a more updated base image, you'll need to downgrade. arch linux allows this with more freedom, since its more modular.
i havent used fedora for a few years now. used it back when red hat quit doing desktop images, didnt stay long and switched to slack.
i prefer archlinux because it's 300mb'ish iso, allows lvm, luks from live cd, doesnt have a text-based installer but install scripts, rolling release system (prebuilt packages/packages built from src using abs/aur, testing repo), customizable/modular, cli package manager (pacman ), systemd, grub2..
basically, if you like bleeding edge and power to yourself, try archlinux. read the wiki, begginer guide, install guide. first time i did it, i used another pc to help me go through all the steps.

When you're interested in Linux you can take a easy to use Distro like Ubuntu.
Packetmanagement resolves dependencies autocratically and nearly each software is available as a precompiled Packet
Also such Distros are running 32 and 64bit Programms out of the box.
If you want to learn linux in deep (and have enough time to solve issues) i recommend a Distro like Arch or Slackware.
I use Slackware64 and learned a lot about Linux and the packet and library dependencies.
Because the Packetmanagement does not resolve dependencies.
Even GUI Tools are rare on this Distro, you have to struggle with config files.
Slackware is a pure 32 or 64bit Linux (can be build to a Multilib Linux).
For Example the Android SDK mainly uses 32bit.
Maybe you should try some Distros and use that one you feel familiar with.
Also there are good Resources out in the net which you should read (Filesystem Hierarchy Standard, File Permissions, Basic Shell Tools)
Google and en.wikibooks.org/wiki/LPI_Linux_Certification would be a good starting point.
You could also try some Live-CDs, mess with it and when all went wrong only reboot.
Good Luck
Indeed, start Ubuntu, you can even stay with it if you like. But Arch and the install guide give you a good grasp on how Linux works.
Of course, you can develop apps in Windows or OSX, and OSX and Linux are the only two that allow you to build Android from source (basically ROM development). You also need to know Java to develop Android apps, less fun than screwing around with Ubuntu lol.
Good luck!

Just to give one final thought, I think Slack would be a better learning experiencing, since it's even more close to Unix than Arch. With Arch you learn a lot, that's a fact, but with Slack you understand even how libraries and dependencies work, kinda the hard way, since you don't have a package manager to take care of it for you.
I think both might be a steep (maybe too steep) learning curve, and Ubuntu will be easier but, Ubuntu does things more their way. It's Linux, but things are different. Eventually, you'll know what i mean.
sent from my i9250
Thanks for the input. That's something to look into for sure. I am in no rush to just jump in and try it. I'd really like to learn everything on a basic level like that first.
I'm trying to get the research down before I start messing with the development.

Even if it were possible, why do you want to add another camera to the device?
Edit: You however did pique my curiosity whether this can be done and perhaps it can!. The camera model you have mentioned is supported by the Linux UVC driver (check here: http://www.ideasonboard.org/uvc/). This is a part of the standard kernel source (it's located at /drivers/media/video/uvc)
So basically, you need to compile the 'uvcvideo.ko' module. I don't know if this can co-exist with the existing camera driver, so you may have to disable the driver for the front / back cameras and compile the uvcvideo driver in or as a module.
Good luck!

The stock front camera has a bad low light visibility where as the microsoft lifecam has a very good visiblity even in the room with all lights off, at night ofcourse (the light source is only the screen itself falling on my face)
As i already know this is possible. Take a look..

I think there is no option other than to install linux on my pc and give a try.
Any suggestions would be appreciated.

Although unsupported, I believe it is possible to build the kernel on Windows under Cygwin. Have a look here for setting up the build environment etc on Windows: http://forum.xda-developers.com/showthread.php?t=1686310. Note that Samsung's recommended toolchain is actually 4.4.3 (but you might be able to find that with a bit of Googling).
Alternately, I can build the uvcvideo.ko module for you. However, I am going away from tomorrow morning for a long weekend, so you might have to wait till Sunday evening unless I manage to find some time to do it tonight itself. Otherwise you can try requesting someone else here to build it for you - it only takes a few minutes.

This is more a driver issue than kernel. And even though there may be linux drivers for your webcam. Google has not yet fully merged the android kernel into the linux family, so it may not be possible to port. I wish you all the luck though :fingers-crossed:

Seems like the reverse direction actually. You already got your module compiled and now you are changing the source?

Here you go. This is an ODIN flashable kernel (unzip it and flash the .tar file using the PDA section in ODIN). The module is located in /lib/modules.
PS: The kernel is compiled from stock sources, except for addition of the lulzactiveQ governor (pegasusQ is still default) and a couple of other patches (missing touchkey drivers and AndreiLux's firmware naming / boot-up time reduction fix).
Edit: Added only the module in uvcvideo.zip. Unzip & copy it to your phone somewhere and insmod it to load. If it doesn't work with your stock kernel, please use the full kernel against which it is built (provided above).
And here's the Samsung stock kernel from DDLJ3, in case you want to revert back. Again, ODIN-flashable after unzipping.
I might be a bit off topic:
Is there anyway to load an under volt module?
I've always been using Tegrak over clock ultimate but it's not updated since 2 months..
And it's obviously not working on our beloved gsn2
I'd love to stay as stock as possible but with under volt

can i use uvcvideo.ko provided in this thread? how can i do?

Is file uvcvideo.ko specifically for galaxy note or can i use it on a different device?
Is this still required for UVC video to work or does it work on the latest ROMs/kernel?
I've read it works out of the box on the Nexus 7 but I don't have webcam to test on my Note2.
Nevermind. I tried the app Dashcam which checks for UVC driver. GFs S3 does not pop up an error while my Note2 (and my HTC Desire 601) do.
Hi,
I wanted to ask some question so please we should keep this thread as short and qualitative as possible, so
1) I want to have a custom ROM (CM in this case) but without transforming my device in to a Xperia S especially without loosing the CPU power, normally - with what I know- the kernel should detect the processor as a 1.7 ghz but I read that if you put the Xperia S ROM it won't so (will see it as 1.5 which is STRANGE to me), is there any CM for xperia sl (It sounds rhetorical to me as I searched and didn't find - looked up also freexperia) so basically what should I edit/do to get one?
2) I saw some projects on hardening the kernel (with grsec, yeah spender did a "nice" job, although Ac1db3atch3s crashed gradm ), so what should I do to put a hardened kernel in to the above ROM? I'm not particularly interested in "paranoid-secure" kernel , but more in to a flexible / light / USEFUL / robust one , so which one you recommend (with what patches) and how do I build everything and put it on CM ? [I'm on Arch Linux but I have also Windows if that it's a MUST]
3) Even after installing busybox , the system is still far from Linux as there are missing options like for example, lsof it's just lsof with no options, netstat is without "-e or -p" although it is as an option but doesn't show the processes or details, ls is lacking of -h and -c , and this question maybe returns to #2 as maybe there is a ROM out there with already packed "correct" binaries.
What should I do to get those?
4) What are the best applications you recommend (I saw guardianproject but not particularly interested in tor sub applications) to have full control on what's going on the OS?
Thanks.

Hi,
I wanted to ask some question so please we should keep this thread as short and qualitative as possible, so
1) I want to have a custom ROM (CM in this case) but without transforming my device in to a Xperia S especially without loosing the CPU power, normally - with what I know- the kernel should detect the processor as a 1.7 ghz but I read that if you put the Xperia S ROM it won't so (will see it as 1.5 which is STRANGE to me), is there any CM for xperia sl (It sounds rhetorical to me as I searched and didn't find - looked up also freexperia) so basically what should I edit/do to get one?
2) I saw some projects on hardening the kernel (with grsec, yeah spender did a "nice" job, although Ac1db3atch3s crashed gradm ), so what should I do to put a hardened kernel in to the above ROM? I'm not particularly interested in "paranoid-secure" kernel , but more in to a flexible / light / USEFUL / robust one , so which one you recommend (with what patches) and how do I build everything and put it on CM ?

Hello @0fo,
I'd try to be as qualitative as possible (As you mentioned)
1.) A Custom Rom won't affect the CPU speed of 1.7GHz, It is the Kernels that can give you other CPU speeds.
So after installation you need to edit the kernal using third party tweaks. And considering the research you have done This wont be so hard to overclock.
2.) About Hardened Kernals, You can not do anything right now. Only Stable Kernels Available Are For Nexus Devices. . For Building Your Own Kernal And ROM Please refer to Guides Available for The Same.
3.) Unable to Understand Completely, A little more feedback on your problem would help.
4.) For Complete Control on the OS. You dont need applications but a working compiler and modding shell, Not much can be done from phone itself.
Install Android kitchen and Cagywin. You would have complete control.
If my time given to you was helpful please press thanks button!

Thank you for your reply,
1) When I mentioned ROM and not the kernel I was referring to http://forum.xda-developers.com/showthread.php?t=2245327 under "General" which says "Any ROM for S will Work for SL BUT you lose 1.7GH Speed" So what should I do, should I download the "nozomi" image and than tweak ? Even though I don't know were to tweak or how because I'm new to android and I rooted my phone just yesterday, but I have experience with Linux systems / also enterprise.
2) Yep
3) On Linux when I want to list files/dirs I run ls -aclh but -c and -h options are missing on the ls binary installed on my phone, also while using netstat and lsof some useful options are missing, it's like the system is build to not let you know which process is using X connection and you can't track which process has opened the socket , for example I see a socket communicating with a amazon cloud server constantly on port 4244 or similar but don't know what and why which makes me curious.
4) will try those out.
