Hi!

New realtime trees should be available at kernel.org.

Trees are available at

https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git/log/?h=linux-4.19.y-cip-rt
https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git/log/?h=linux-4.19.y-cip-rt-rebase

And their content should be identical.

This patch merges 4.19.148-stable into -cip-rt (because that's what recent -rt is based on, and older -rt tree is too old). Unfortunately, that brings regression with ethernet on Renesas Arm64 targets, which will prevent boot, and fail tests etc.

Kernel that should work ok on Renesas Arm64 machines can be obtained by reverting fb3a780e7a76cf8efb055f8322ec039923cee41f "ravb: Fixed to be able to unload modules" on top of -cip-rt release.

Best regards,
Pavel

So we're releasing a Kernel that we know doesn't boot on one of CIP's reference platforms? Or did you already revert the above patch as part of your release?

Thanks, Chris

Yes, I did that, as the changelog explains. Sorry.

I had to select from few bad options: 4.19.147-rt release is not available and previous release is too old. So -cip-rt is based on 4.19.148-rt, and it brings in the bad commit.

I thought about reverting it for release, but all I'd get would be rejects, as it really needs to be solved in -cip, not -cip-rt.

Proper solution is likely updating 4.19-cip to 4.19.148, first. Then figuring out what is the clean way to solve the problem, and then creating new -rt release. But that will likely take more than few days, and it will end up with different release number.

I can create new -cip-rt release when that is done.

Best regards,
Pavel

Hi,

This issue seems to occur randomly.

# cip+rt kernel
NG: https://lava.ciplatform.org/scheduler/job/57129

    https://lava.ciplatform.org/scheduler/job/57842
OK: https://lava.ciplatform.org/scheduler/job/57851
    https://lava.ciplatform.org/scheduler/job/57841

# 4.19.148+cip kernel
NG: https://lava.ciplatform.org/scheduler/job/58836
OK: https://lava.ciplatform.org/scheduler/job/58837

We may need to confirm these relationships with CIP kernel patches.

Best regards,
Nobuhiro

Yes, and the revert is now queued to 4.19-stable, too.

So.. what do we want to do here?

We can merge 4.19.151 to -cip when it is released, and I can then release new -cip-rt that works on renesas boards...

Best regards,
Pavel

Perhaps 4.19.151 will be released this weekend. And this week is the release week of the CIP kernel. And I think we can use it to release the cip-rt tree.

Sorry, this may be wrong.
If 151 isn't released this weekend, I'll cherry pick this commit, and release new CIP kernel.
