Hey everyone,
This is mainly a heads up for kernel devs who are looking to complete an AOSP compatible kernel for the Rezound. Seeing that the Linux and Android trees have finally been merged (at least kernel wise) it should be SLIGHTLY easier to build a working Rezound kernel from source. I'm sure lots of work will have to be put into the process and perhaps Devs will only really be able to backport from 3.3 to a 3.0.x kernel, but this release improves my outlook of CM9 and other AOSP projects for our device.

Thanks to all the Rezound devs for their hard work and I look forward to seeing what the future brings.
Best of luck,
DeathByFugu (Josh)

hi guys, did HTC ever release the source code for the 2.1 update?
No. htc are bell-ends and don't even release driver source code, let alone code for their "superior" gui. Hence why it takes a while to port newer versions of android to the hero. Developers have to implement loads of dirty hacks and backports using kernel binary blobs they manage to extract from the 2.1 upgrade.

well thats just bad news!!
but they did afaik release source code for the kernel for many of their phones didn't they, what i would like to know is what does this mean to developers, what can they do with the kernel source?
The kernel is just a modified linux kernel, which has been open source since the early 90's.
Developers can do quite a bit with the kernel, is is basically the bridge between hardware and software.
However, despite running Debian since Etch was the latest stable release, my knowledge of the linux kernel is limited, so you would have to ask a developer for specifics.

thanks for your help
info on webkit source please..
i was at HTC's Developer Center and i noticed that HTC released the "webkit source code" for several "Sense UI" models, including the HTC Droid Eris, which very much shares our beloved Hero's specs...
i was wondering is this webkit compatible with our GSM Hero, and why didn't HTC release the webkit source for the GSM version?
the reason i'm asking is because i want to take out libwebcore.so alone and patch it, and replace the one in Hero...
I have a general question about building the Android kernel. For understanding purposes, I'm a C/C++/C# developer (and Android application developer), but have little functional knowledge of the Linux kernel.
With regard to porting Android, I'm curious how one builds the latest Kernel. The Android Kernel is not simply the standard Linux Kernel branch, correct? Where does one get the latest "Android" Kernel from? Does Google host a Kernel site as part of AOSP that we can sync with?
Once you have the latest Kernel, is it simply a matter of ensuring the Make file is accurate, adding the appropriate device drivers (as .so files?) for your particular hardware, and performing a Make? Then I assume you can update your device's Kernel with the one you've buildt?
In closing, for example, I'd like to sync the Android 3.0 Kernel, update the drivers necessary for my EVO 4G, build the latest Kernel, and then flash it to my phone. Just looking for some insight as I start getting educated on the topic.
Thanks for any advice you can offer!
Actually, the android kernel is very similar to the linux kernel (well it is based on the linux kernel). You can get the kernel from here: http://source.android.com/source/downloading.html. You can also take a look here: http://elinux.org/Android_Kernel_Download and here: http://elinux.org/Android_Kernel_Features. It will be quite difficult to build a kernel for your device without the source (there's none for 3.0.1 for your device), but you could still build it from a lower kernel version: http://linux.softpedia.com/progDownload/HTC-EVO-4G-Sprint-Kernel-Source-Code-Download-58254.html.
Thanks for the info, Theonew. When you say that it will be difficult for me to build the kernel for an EVO without the source, is that because the vendors (Qualcomm, for example) haven't made source for their devices available, so it's hard to build the drivers (.so files?) that are compatible with the latest kernel?

HTC hasn't released the source of the kernel v3.0.1 (which comes in Ice Cream Sandwich) for your device (since it's not available for your device...yet at least).
Since linux Kernel 3.3 is out with built in Android code. I would like to know what would that mean to us P500 users from a developers point of view. Would we get something out of it?
If you don't understand the new features than it won't make a difference for you between running your current kernel and the newer one.
Hi! This is maybe a general dev question, but I'd like to get an answer anyway:
what is exactly the link between an Android release and the kernel it works upon?
I noticed most recent releases use 3.0+ Linux kernels, and others (like the DSCs) use the Phoenix Universal Kernel, which is based on a 2.6.35... So I wonder: is ICS/JB in any way dependant on "newer" kernels?
I understand the answer must be closer to "no", since the pre-alpha build also uses a fork of the PUK, but the fact that it uses a *different version* makes me wonder how much work does it take to get a kernel ready for a newer release, and most importantly... why?
Thanks a lot! Total n00b here, but eager to know more.
Newer kernel not required at least for ICS.
All GB/ICS kernels are based on this kernel (and it's a Dell's lie about using same sources for 407 release as SoD was fixed there without switching timer source):
http://opensource.dell.com/releases/streak/4.05_and_4.07/
kibuuka successfully applied kgsl/genlock patch and it's the only thing actually needed for ICS.
List (a bit old) of changes in Phoenix kernel and later derivatives:

Are there any ROMs, based on the leaked kernel sources below?
https://github.com/rmtew/MediaTek-HelioX10-Kernel
All the ROMs, I've seen are based on prebuilt kernel.
Until we havent full kernel source we had to use prebuilt kernel. Nofearnohappy is trying to complete the source. Now its booting but still some things is broken
I would like to port SailfishOS, but for that I need the build the kernel from source.
On Nofearnohappy's github you can find source but i think it's not worth to spend so much time on building not fully functional rom
