AOSP with Kernel 6.1 for JH7110

[Chang Rebecca Swee Fun]

We have ported some patches for JH7110 into kernel 6.1 (Android common kernel).

Repo: https://github.com/rebeccasf/kernel_common/tree/android14-6.1-lts

But we noticed there are some issue during init on boot.

Boot log

Before the build, we merged the defconfig with Android config fragments, but we saw a lot of configs are not made into final .config. We are not sure whether this will impact the kernel init during boot.

Merge config fragments

Is there any init related kernel code for Android?

Regards,

Rebecca

When you are facing an error during boot,

try searching some keywords at  https://cs.android.com/

For example,  you will find following code with "BlockDevInitializer::InitDevices" : 

https://cs.android.com/android/platform/superproject/+/master:system/core/init/block_dev_initializer.cpp?q=BlockDevInitializer::InitDevices

Alright, we are still debugging the issue currently. Regarding the AOSP repo, I noticed the manifest is pointing to latest master branch, we did a repo sync and now it doesn't compile successfully. May I know whether you will rebase and lock down a fixed version repo for the code base?

[Peter Yoon]

If there is a fixed AOSP release (like android-13.0.0_r1) which support riscv64, we can work based on that release. 

But there is only the master branch that is supporting riscv64.

You can sync to a certain good version of master, and keep that source for a while.

On my side, last good version was 2023-07-11.

I think someone asked the same question (regarding versioning control) in Android SIG:  Android SIG topic - Google Docs
I will probably sit-in the meeting to find out more information.
Thanks.
