If we are developing on a new LTS kernel before the matching Android platform is released, we have to choose some unrecommended combinations, like android13 with 6.1 kernel or android 14 with 6.6 kernel. It works in most cases from our experience, of course we have applied some patches on AOSP code to support this, most of them are to bypass the libvintf check.

For example, applying this patch (

https://android-review.googlesource.com/c/platform/system/libvintf/+/3250976) to bypass following errors when boot:

09-05 09:07:05.572 4926 4926 F DEBUG : Abort message: 'Check failed: ret < Level::LAST_PLUS_ONE Convert Android 14 to level '8' goes out of bounds. Fix by adding a new Level enum.'

So if such patch can be ported back to the android13-gsi branch, we can successfully boot the device with the released GSI image + 6.1 kernel.

Can you develop on aosp/main? If you are developing on aosp/android13-gsi, then you should use the old kernel. android13-gsi may be missing other things to work on updated kernels, and it is not supported on newer kernels.

Thank you for your reply. For develop purpose, we can work on aosp/main. But if some customer wants to pass Google certification with such combinations, they have to use the GSI image built from aosp/android13-gsi, and this doesn't work.
So the conclusion is that we should tell the customer not to use newer kernel on older platform.

Marked as fixed.

You should recommend a newer kernel and the newer platform!

Even on old platforms, you should use new security updated kernels, but they must be from a supported version.
