Test results summary
--------------------

V4L2 Compliance on the vivid driver.

This test ran "v4l2-compliance -s" from v4l-utils:

Hi Guillaume,

I have a few questions/suggestions:

I'd just link directly to the git repo instead of the wiki: https://git.linuxtv.org/v4l-utils.git

You should add the v4l-utils commit that's used to compile v4l2-compliance.
That's important information to have. I assume that this test always uses the
latest version of v4l-utils?

I assume this is the version of the host kernel, right? Perhaps calling this
"Host Kernel:" would be less ambiguous.

Even if everything was OK, I think it would still be useful to have a link
to the full test report.

Sure, I thought this had been agreed before but it's easy to
change.

This information is in the detailed results, but the detailed
results are only shown when there are some failures.  So we'll
rework that a bit.

For example, from the v4l2-compliance-uvc report:

The git repo and commit hash here show you which version of
vl4-utils was used.


At the moment, the v4l2-compliance is part of a rootfs which gets
updated each time kernelci.org production code gets updated,
which is typically once a week.  This can be improved to have the
rootfs updates independent from the rest, then we could trigger
rebuilds every time v4l-utils changes, but there are a few things
to take into consideration before we can do this safely.

I have to say I fail to see any ambiguity here: KernelCI is about
testing kernels, and this tells you the kernel revision under
test.  Calling it "host" kernel might actually be confusing when
running with QEMU as people may think it's the version on the
host server running the test.

Yes, that is essentially the same issue as with the v4l-utils
version as I described above.  The detailed results show a link
to the console output, which isn't just a clean v4l2-compliance
log but it's better than nothing.

We may also add a feature to publish some files alongside the
parsed test results, and in the case of v4l2-compliance it would
typically be the plain output of the test suite that developers
are familiar with.  It's not a supported feature right now as
only the raw console log is sent from the device to the database.

Best wishes,
Guillaume

I don't think it has to be updated every time v4l-utils changes, at least
for now, as long as it is clear which v4l-utils version is used.

What confuses me is that the kernel above says: media_v5.1-2-16-gfc8670d1f72b
but the commit says fc8670d1f72b746ff3a5fe441f1fca4c4dba0e6f.

So the hashes are different, which led me to conclude that one referred to
the host kernel and the other to the kernel under test.

Where does the string "media_v5.1-2-16-gfc8670d1f72b" come from?

This is the output of "git describe", except that the slash in
the tag name was replaced with an underscore (I know that's not
great, but otherwise it causes some issues with the path on the
storage server).  The media/v5.2-1 tag has been created since
then, but if you run this:

$ git checkout fc8670d1f72b746ff3a5fe441f1fca4c4dba0e6f
$ git tag -d media/v5.2-1
$ git describe
media/v5.1-2-16-gfc8670d1f72b

and fc8670d1f72b is the beginning of the full hash.
