What do you make of this.

I'm no Android or Linux expert or even Above Beginner really so would appreciate any info available.
Is it usual to base newer FW on older Kernels. Someone also says Android 1.6 was based on 2.6.29???
Cheers
It shouldn't really make any difference in this case. It's definitely not a 'fake' Froyo as that person is calling it.
When comparing Archos' kernel (it's included in their GPL package) with Android's kernel 2.6.29, there are a lot of differences, about 1000 files changed. I guess they've added some omap patches (I'm not allowed to post external links, yet, so let me describe the git repository: git (dot) kernel (dot) org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git) or even use the omap kernel, because Archos' kernel suffix is also "-omap1".
Good to see that the omap guys are up-to-date with their kernel. So... let's try to make it work on our Archos devices!

I have a Garminfone and have done a lot of Rom hacking with it so far, enough that I want to port cyanogen to it now. In the config.gz file there are references to Garmin specific items... how do I go about figuring what is included in the kernel and if the stock one might work with the right config settings. I know that they load a few ko modules at boot, but I don't know the requirements for when they must release kernel sources and what to do with it if they do.
I know they have released some in the past for the a10 but not the a50, and none for the 2.1 build.
I do know that they use the 2.6.29 kernel so is there a chance that I could use the current kernel with froyo?
Any assistance would be appreciated.
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).
I have been breaking my head on finding some guide on how to upgrade earlier version of android kernel to new one. I find out that it can be done with patching(???) with some files that will include new kernel files to old kernel and upgrade it to another newer version. In my case I have tegra device with 2.6.32 kernel but there's nvidia tegra git and newer kernel versions(even 3.0) I think that files like this or this are kernel patches?
Please, help me?!?!
If this isn't feasible, please, tell me, I won't break my head anymore!!!
Thanks

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:

Hello, I'm newbie dev trying to build CM13 for Lenovo Phab plus.
I think I'm almost finished with device and vendor, but I cannot figure it out what to do with kernel.
The circumstance is,
I have a stock kernel source which runs in 5.1.1 LP, with version of 3.10.49.
What I want is to make kernel compatible with 6.0.1.
I already know that linux kernel version doesn't have to be exactly same with new Android OS versions and I can just make a few patches in order to run kernel in higher OS.
So I googled and studied(?) for 2-3weeks, but got not many useful informations and I still cannot figure out where to find required patches for 6.0.1 .
So here's what I am not sure about.
1. I found that I can either upstream, merge, cherry-pick kernel sources from higher OS. For instance, if I merge kernel patches (starting from 3.10.50 to 3.18 step by step) and check if the kernel compiles successfully, is this a right thing to do? I am confused whether merging or cherry-picking is required for my situation.
2. I see lots of commits when comparing with other kernel sources in github. How do you find those kinds of patches? -> just keep compiling kernel and if error comes out->search->commit
Always this pattern goes again and again till boot properly?
3. i'm quite curious with backports. What i know is that "backports" are the files which is compatible for lower version kernels. For example, backported audio driver originally based on 4.9 can be used in kernels with version below 4.9. Is it right?
4. If there is an useful links, anything could be helped a lot.
THANKS IN ADVANCE.
