[PATCH v11] drm: Add initial ci/ subdirectory

[Maxime Ripard]

Replying one more time, because I certainly don't want to create any
hard feeling here.

Your (and others) experience certainly isn't. It is valuable, welcome,
and very much appreciated.

However, my questions and concerns being ignored time and time again
about things like what is the process is going to be like, what is going
to be tested, who is going to be maintaining that test list, how that
interacts with stable, how we can possibly audit the flaky tests list,
etc. have felt like they were being handwaived away.

I'm not saying that because I disagree, I still do on some, but that's
fine to some extent. However, most of these issues are not so much an
infrastructure issue, but a community issue. And I don't even expect a
perfect solution right now, unlike what you seem to think. But I do
expect some kind of plan instead of just ignoring that problem.

Like, I had to ask the MT8173 question 3 times in order to get an
answer, and I'm still not sure what is going to be done to address that
particular issue.

So, I'm sorry, but I certainly feel like it here.
