Hi,

You can find the following sentence on the page.

an SLTS branch may include larger changes to support new hardware, to bridge the gap between SLTS branches.

Oh, I missed the sentence. Thank you very much for telling it.

In addition to these, we may need to describe the supported hardware (CPU, boards) and
test environment as well.

Is the backporting limited to the supported hardware?

Best regards,

Hi,

Thanks for pointed out.

I think we need to write much clear to mention what kind of patches we can accept to CIP SLTS tree and how to approve(?) it by CIP.

Agree.

We think that we need to add the following sentences.
---
We do not apply patches that have not been applied to upstream
(Linus tree:https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git).
If you want to add new features or hardware, they need to be applied into upstream.
Also, you may not be able to easily apply the patches on Upstream. In such a case,
you need to describe in the commit message of patch what modifications have been made
from the original patch.

In addition to these, we may need to describe the supported hardware (CPU, boards) and
test environment as well.

Best regards,
Nobuhiro

Hello,

I have a question about CIP kernel maintenance policy.
Can CIP kernel accept backport patches for new hardware support (not
only fixes)?

I read the following document and it seems to describe only acceptable fixes.
https://wiki.linuxfoundation.org/civilinfrastructureplatform/cipkernelmaintenance

On the other hand, Current linux-4.19.y-cip branch accepts some hardware
support patches such as RZ/G2E(r8a774c0) from upstream.
So I wonder if some policy about new hardware support exists.
