[PATCH v2 0/2] media: renesas: vsp1: Fix display pipeline regression

[PATCH v2 0/2] media: renesas: vsp1: Fix display pipeline regression

[Laurent Pinchart]

Hello,

Two commits merged in v7.1-rc1 introduced a regression in the display
pipeline. This series revert them to fix the regression.

The commits were meant to fix v4l2-compliance failures. Those failures
have never caused any issue in production use cases, and have never been
reported as issue by anyone. Reverting the commits is therefore the
safer option, to give us more time to address the v4l2-compliance
failures in a better way.

[PATCH v2 1/2] Revert "media: renesas: vsp1: Initialize format on all pads"

[Laurent Pinchart]

This reverts commit 133ac42af0a1b389e8b7b3dc7c1cc8c30ff162b6.

The change to format initialization, along with the change to format
propagation in the BRx in commit 937f3e6b51f1 ("media: renesas: vsp1:
brx: Fix format propagation"), broke configuration of the DRM pipeline.
Revert it to fix the regression.

The original commit was meant to fix a v4l2-compliance failure, with no
known userspace applications being affected beside test tools. Reverting
is the simplest option, a more comprehensive fix can be developed (and
tested more thoroughly) later.

I don't see these commits in any of the stable branches. Does the
message mean the mainline tree, not the stable tree ?

Given that this series should be merged in v7.1 as a regression fix, why
should it CC stable ?

You did not get the memo. From now on, all patches in the kernel need
to be SoB my me :P

Sorry about that, Yesterday I had to recreate the local repo and
forgot to set the proper committer. It should be fixed now.

Ah right. But I don't think that's relevant. The commit is from the
master branch of the stable tree, which simply mirrors Linus' tree. It's
not in any stable branch.

$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git stable
Cloning into 'stable'...
[...]
laurent@killaraus ~/src/kernel $ cd stable
laurent@killaraus ~/src/kernel/stable $ git branch -a --contains 937f3e6b51f1cea079be9ba642665f2bf8bcc31f
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
laurent@killaraus ~/src/kernel/stable $ git tag --contains 937f3e6b51f1cea079be9ba642665f2bf8bcc31f
v7.1-rc1
v7.1-rc2

This means the commit hasn't been backported to stable, it has just been
merged to mainline.

If the purpose of this is to check if the commit has been merged in
mainline, I think the message should refer to mainline. If it's to check
if it has been backported to a stable kernel, then those are false
positives.

Note that commit ID change when they're backported. If you want to check
if a commit has been backported, you'll need to grep for

    commit ${upstream_commit_id} upstream.

in commit *messages* of all stable branches.

No, it hasn't been backported.

You are completely right. And we have been doing this wrong for a long time....

We have a challenge that it is not trivial to fix. The builder do not
have a clone of linus-stable, it queries it with something similar to
"git ls-remote". So I cannot use "git log | grep".

Ideally we could have a web server to check if a sha has been
backported, but that does not exist yet. It could probably be a nice
little vibecoding project.

The question right now is if it is best to disable the check
completely or keep it and live with the false positives.

Need to check with my pillow.

You had me interested until I read vibecoding. /me walks out the door.

Given that the check essentially flags any patch that Fixes: a commit
present in mainline, I don't think we should keep it in its current
form. If desired, we could replace it with a check that flags Fixes:
without CC: stable, unconditionally. I think that's too strict though,
so it would need to be a warning that wouldn't block merging.
