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.
I'm pleased to present my MoDaCo Custom ROM for the Samsung Galaxy S! READ THIS WHOLE POST BEFORE YOU START! No, really, it contains everything you need to know. wink.gif
This ROM is the 'starting point' for my Galaxy S custom ROMs.

Does this ROM fix the ram issue so that all 512MB of ram is utilized?
Congrats on being the first custom rom here.
Congratulations! I don't have a phone yet but I am very pleased to see a custom rom already!
woohoo custom ROMs already. Guess I'll be getting myself the phone after all.
umm.. but in another thread people where saying that it wasn't gonna be possible because samsung encrypt their drivers etc. so this mean they did release they drivers? and there is gonna be alot of custom rooms for galaxy gravity?

No I said it would be near impossible to get roms from other sources like Sense roms or Froyo on because of the driver issue. I never said you would never see custom roms. The only roms you are going to see are one's based off of Samsungs release.
Hold on, hold on. So even though Samsung released the Galaxy S' driver source code to the public, it's going to be "near impossible" to port Sense and FroYo to the phone? I may be ignorant but I'll just ask with ignorance, how do you figure?

Download the source code..... ok now open it and go to GalaxyS_Kernel.tar.gz. Now in there just enter the first folder then go to modules. Go to Dpram. Open up any of those files in notepad. You should see written non-compiled code right? That is fine now go back to the module folders and go to S3cbc. Now open up s3cbc_module.o. Does that look like non-compiled code? No it doesn't. It's either already compiled or encrypted. That's what I mean

Quick question, does that mean any custom rom that is release will be based off the official rom they release which has Touchwiz backed in? If so, does that rule out a plain vanilla android rom for this device? Thanks for your help and appreciate the knowledge.

No it doesn't rule out plain vanilla android rom. Yes they will all be based on Samsung but rom makers can take out all the touchwiz garbage and throw in another launcher like adw or Launcherpro.
That's what I wanted to hear. Thanks for the help. Now if I only could decide if I should keep the Nexus One or purchase this phone..... Decisions, Decisions.

So they can easily be decompiled? If it's source code why is it already compiled?
dont go too deep into specific things that we may not even need (we are not coders here) but the source code for basic hardware that we need to get things going are already there.. things like camera, wlan, etc. btw, do u know what s3cbc is for?

What about s3clcd? Here is a little copy and paste of some of the garble that was in the compiled file
screen width=%d height=%d va=0x%x pa=0x%x
I would go out on a limb and say those are video drivers. The one's that have been encrypted on all other samsung phones.
Also in s3cbc there is some code at the bottom
PVRSRV_PIXEL_FORMAT_YUY2 PVRSRV_ERROR_FIFO_SPACE char ui32ByteStride psDevInfo PVRSRV_PIXEL_FORMAT_PAL1 PVRSRV_PIXEL_FORMAT_PAL2 pfnOpenBCDevic
If you don't know the Galaxy's gpu is PowerVR SGX540 and YUY2 is a colol format for video screens
http://www.fourcc.org/yuv.php#YUY2 and Pal is of course a European video standard.
they are not encrypted, they are object codes in machine language for arm.. and why we need that again for custom roms?
Wanted to test modaco ROM but they are not free.. Any kind souls upload and share ?

How much free ram have you got? Considering flashing and rooting, but not sure if it's worth it right now. Meh 10£ isn't that much think I'm gonna give it a try.
EDIT: Just flashed, but now I don't have root access(says access denied when I try to access the /data/data folder). Thought this included the rooted PDA file or do I have to flash that again with odin?
EDIT2: Scratch that I forgot to press the allow-button on my phone after sending the Super-user request..

I want to start this thread to keep up the progress on the port.
the bad news is that the SDK is incomplete for now, so (like other devices)
we will have to write our own code for the OS, the nook community
has done a wonderful job writing their own libraries and stuffs, so we will have to do the same.
Instead of pursuing different goals, let's focus on one thing at a time.
since GSM and CDMA versions are already out, it seems we suffer the same bugs, so for now let's unite strength and knowledge to overcome these.
I propose that the first goal to fix is the SurfaceFlinger, so we could at least see the apps, the buttons and the notifications.
it is currently throwing this:
04-06 22:01:35.495: ERROR/Surface(2960): dequeueBuffer failed (Out of memory)
this could lead us that it might coudln't start because of some malloc malfunction or something.
also that pvrsrvinit bugs me a lot.
update:
8/APR/2011
since DiP7 could fix SurfaceFlinger and other things using a different build from the GSM kernel, we have to dig deeper
======================================
CURRENT GOAL
Rebuild Kernel

Current approaches:
*none
Post any finding, guessing or anything, and please, please don't be afraid to ask anything you have a doubt, as a Dev you should not know everything, so we can help us each other

Mmmk.. Let me tell you a story.
A long time ago in a galaxy far away... No, that will take too long. In a nutshell, one third of the answer is here, another third is here and the rest is here. I'm not trying to be intentionally vague, I just haven't figured out how these three fit together yet.
Of course, there could also be some bit of code that I missed... some telling line in a debug log that I overlooked or some driver or library that I could have decompiled to sift through its juicy secrets. There could easily be a fix that would take seconds to add and make the whole thing fall in line...
Or we might have to work it from the ground up.
Either way it will happen. It's just a matter of whether it will happen next week, or next month.
(Watch it be a misplaced semi-colon, or a bad symlink... that's how these things go.)

The kernel source that you have linked to is 2.6.35.7 for the Nexus S gingerbread and is not fully maintained by samsung but rather by google.
However I do not think you are wrong that there is a problem somewhere in the kernel. The kernel that has been released for the galaxy tab is a mess of horrid code, I have had to re-write parts of kernel drivers just to get them to work under linux, I would not be surprised if similar patches are needed for honeycomb

Yes, and it contains some support for our device (s5pc110), and some more that can be added (pvr) and the architecture necessary to fully support HC without patching the build itself. If we work only towards patching the system build to communicate with the hardware, we won't be able to run AOSP hc versions when the source drops without going through the same painstaking process of hacking the system to function (while creating numerous faults causing FCs in the process). If we build a new kernel, we can get the hardware to communicate in the way future android versions want it to and we can then do what we want with ease.

Kernel debugging over USB = adb shell cat /proc/kmsg
You can make any kernel work for any device as long as you add the **** it needs. Just takes time. Working on it now.
Goal and tools updated*

You don't know what a kernel panic is do you?

I thought that linux throws a dump log when it makes a kernel panic specifying the memory address and the cause of crash
Hello Comm. and Devs,
For our Archos there are now many custom rom-images and experimental distris of linux and so on and every "rom" has its own kernel and init which have to be flashed and it seems it is only possible to have one kernel and one init.
I want to test as many roms, plasma, ics alpha, ubuntu, 3.2.80 with busybox and adobe, etc. for shorter or for everytime. And when Archos brings ICS finally i want to upgrade of course, without losing apps and settings etc.
Now i am on rooted 3.2.79 with chainfire 3d and i dont know if it makes senes to upgrade to 3.2.80 custom rom from surdu. Okay, vibrator and so on and some goodies, sounds nice, therefore i want to test and perhaps revert it later.
Which roms are compatibel with each other and which not?
Which rom is how much recommend?
What are the differences between these inits (kernel seems often to be the same seen by its size i think) - is there the possibility and the evidence to merge the inits somehow?
Or is there a kind of general initramfs one could take for most roms?
What rom has which kernel in which version and same for initfs?
What are there for possibilities that every image gets it adequate kernel and initfs?
Many of us want multi boot which i think is not really (?) supported for gen9 .
What should be done for compatibility if i want a kind of multiboot?
It would be nice if this would give a set of infos for us all.
Well, no, kernels are not the same. We're not 100% sure for Archos ones, they're currently closed source, but looking at what they fixed in the different releases, I believe there have been changes. Plasma is definitely using a different kernel, ics will require a completely new 3.0 kernel and probably require clear data.
So what you're looking for is not really possible, not matching kernel with firmware is not a good idea. The only exception would be Ubuntu, but that's it.
what about multi-boot menu from open aos?
There are roumors that people have it work but it is not supported.
Dont want to mess all up.
Do you know something or have experiences?

Sorry - about this with multiboot i see there is already a thread.
As the title suggests, is there a kernel for the P605 which will allow SElinux permissive, and therefore allow full linux chroot installs to be completed with relative ease.
I am aware of a permissive kernel for P600, http://forum.xda-developers.com/showthread.php?t=2590311
but assume this will not function for the P605.
If not can the same steps used to make the P600 kernel permissive be applied to a P605 kernel?
Looking for the same kernel
I'm looking for the same SELinux-permissive kernel for P605.
You definitely can't use the P600 kernel as it is for the Exynos variant (P600/01) while ours (P605) is the Quallcom CPU.
Unfortunately the P600/01 was released around the world first with most devs getting the Exynos version. Little developement has been done for the P605 but there has been a little. Just not for an SE-Linux permissable kernel, at least not here on XDA...
Will try to build it myself
I've been thinking of modifying and building the kernel myself. The problem is that there are several kernel source codes on Samsung's website for SM-P605. (I can't post the link here) My device model is SM-P605 without any suffixes so I think it's the first kernel that I should choose.
I think modifying the kernel into SELinux permissive should be as easy as changing a default value in one of the source files and then I can build the kernel using the instructions that come with it. Fingures crossed!
One more thing: in the source code that Samsung provides there are two directories, one kernel and the other platform do I need to build the platform too?

Hey Rhesus007, just wondering if you have made any progress?
Im really in need of a permissive kernel, however i have no knowledge of how to make it etc.
Thanks.
Just dropping back in the thread, still hoping this will happen, as linux on this tab would be really useful imo.
Someone with some dev experience might be able to use the methods used on the note3, which has the same snapdragon 800 soc to achieve this. The basic steps needed to modify the kernel are described in this thread
http://forum.xda-developers.com/showthread.php?t=2471416
if nobody with experience can do this, I might give it a try, but that might be a recipe for disaster....

I've got no experience with this, if you could attempt it, I'm sure a lot of people would be grateful!
For those still looking.
Maybe this might work, don't know if it will work on custom ROM's
