Hey Hans and Mauro,
I remember also on a very little point regarding hardware for testing. But we didn't go in detail again during the summit.
How do we can go ahead here? Are there some test systems up and running somewhere centralized or how it is organized right now?
Currently, different companies host their own hardware labs (Collabora,
Qualcomm, Google, etc.) and these labs serve CI systems like KernelCI or
DRM-CI (and we are currently working on setting these tests up on the
Media-CI). The first step is to either add your devices to an existing
lab or create your own one, by setting up your hardware with the
necessary software, usually Lava, but you can also use Labgrid or
something similar. Let me know which way you prefer, and I can assist
you with that approach.

Sebastian

Can you refresh my memory which processes need more work?
Well I basically remember that we had a bunch of topics in our meetings
that we wanted to skip in order to talk about them here.
We looked at the documentation from DRM and wanted to think about
equivalent policies for media.
https://drm.pages.freedesktop.org/maintainer-tools/committer/committer-drm-misc.html#where-do-i-apply-my-patch
Also there were topics like how to handle backports.
I have the same doubt. As discussed during the summit, Hans and I had some
discussions yesterday, to address a few details. For both of us the process
sounds well defined.
I know that we scraped a lot of topics in the meeting at the media
summit and I am not sure about the scope you discussed with Ricardo
yesterday. So, we don't have to meet if you feel like we covered
everything, just wanted to use the opportunity as long as we are all in
the same place.
Regards,
Sebastian
From my personal notes, this will be the new process:
- committers will merge patches at media-committers.git tree at fdo,
provided that they'll follow the rules defined on a committers agreement
and (partially?) enforced by media-ci checks;
- core committers follow the same rules, with a broader privilege of
changing kernel API/ABI;
- committers will ensure that patchwork will reflect the review process of
the patches;
- maintainers will double-check if everything is ok and, if ok, merge the
changes at linuxtv.org. We intend to rename the tree there to "media.git",
being the main tree to be used for development;
- pull requests will keep using the same process as currently. The only
change is that the media-stage.git tree will be renamed to "media.git";
- maintainers will periodically send patches upstream.
The media-commiters.git tree at fdo might be rebased if needed; the
media.git tree at linuxtv.org is stable. A large effort will be taken to
avoid rebasing it.
We may need some helper scripts and/or use pwclient to keep patchwork
updated after committers reviews.
Such process will start after -rc1.
We intend to rename media-state to media at linuxtv after -rc1.
It is up to maintainers to invite and decide who will be a committer.
All committers/core-committers need to explicitly accept a committers
agreement. We may end starting without it at the beginning, but as soon
as a final version of such agreement is written, everyone with access to
the media-committers tree have to explicitly accept to keep their
commit rights on such tree.
The only part that still require some work is the committers
agreement. I'm working on it together with Hans. As soon as we have
a version, we'll submit a patch to the kernel, to add it to the
media developer's profile[1].
[1] Documentation/driver-api/media/maintainer-entry-profile.rst
For me I think Friday afternoon (probably after 14:00) is the only
option, or perhaps Thursday after the Camera MC.
I can't meet on Friday afternoon. I probably will be on another
event on Thursday (Openeuler MC).

Hans
