Hi all,
This is the second version of a tentative agenda for the Helsinki mini-summit
on June 14-16.
Please reply to this thread if you have comments or want to add topics.
If you want to attend the summit then contact Sakari Ailus
(sakari.ailus@xxxxxxxxxxxxxxxxxxxxxxxxxx). We are very full already (over 20
attendees), so I'm not sure if there is still room left.
The overall layout of the summit is to use the first day to go through all
topics and either come to a conclusion quickly for the 'simple' topics, or
discuss enough so that everyone understands the problem for the more complex
issues.
The second day will be used for in-depth discussions on those complex topics
and on the third day we will go through all topics again and translate the
discussions into something concrete like a time-line, action items, etc.
We have a lot to discuss, so we almost certainly have to split the second day
into two tracks, each discussing different topics. If we do split up, then one
track will touch on the videobuf-related topics and the other on the remaining
topics.
The first day will also feature a few short presentations on various topics.
Presentations shouldn't be longer than, say, 10 minutes tops. Please keep them
as short and to the point as possible. These presentations are meant to get
everyone up to speed quickly. Most of us have an extensive background in video
hardware and the v4l subsystem, so you don't need to spend time explaining
things.
After each topic I've put the names of the main developers active in that area.
If you see your name, then make sure you know the status of that topic so you
can explain it to everyone else. If I think it warrants a presentation, then I
will mention that. Of course, if you disagree, or want/don't want to do a
presentation then just say so. It's a tentative agenda only.
The topics below are in no particular order except for the first one. I am
very pleased that Qualcomm has joined this project so I think it would be
nice to start the meeting off with a presentation on their HW architecture.
1) Presentation on the Qualcomm video hw architecture. Most of us have no
experience with Qualcomm hardware, so I've asked Jeff Zhong to give a short
overview of their video hardware.
2) Removal of V4L1: status of driver conversion in the kernel, status of
moving v4l1->v4l2 conversion into libv4l1. What needs to be done, when
will it be done and who will do it. Driver conversion: Hans Verkuil,
libv4l1 conversion: Hans de Goede.
3) videobuf/videobuf2: what are the shortcomings, what are the requirements for
a 'proper' videobuf implementation, can the existing videobuf be fixed or do
we need a videobuf2. If the latter, what would be needed to convert existing
drivers over to a videobuf2. Related topics (custom/pluggable allocators,
out-of-order buffer dequeuing and per-buffer wait queues) will also be part
of this topic.
Laurent Pinchart and Pawel Osciak with presentations.
4) Multi-planar support. Pawel Osciak.
5) Media Controller Roadmap. Laurent Pinchart has a presentation.
6) TO DO list regarding V4L2 core framework including the new control framework.
Hans Verkuil. Will be a presentation.
7) Status of the Texas Instruments drivers: omapX (Laurent Pinchart/Hiremath Vaibhav)
and DMxxxx (Sergio Aguirre). Probably should be a short presentation.
8) soc-camera status. Particularly with regards to the remaining soc-camera
dependencies in sensor drivers. Guennadi Liakhovetski.
9) Driver compliance. We need a framework for V4L2 driver compliance. Hans
Verkuil.
10) Discuss list of 'reference' programs to test against. Mauro Carvalho Chehab.
11) Adopting old V4L1 programs and converting to V4L2. Hans de Goede?
12) Status of intel drivers. Xiaolin Zhang.
13) Remote Controllers. Presentation by Mauro Carvalho Chehab.
14) V4L2 video output vs. framebuffer. Guennadi Liakhovetski.
15) A processing plugin API for libv4l. Hans de Goede.

It is my understanding that we will also have X11 and gstreamer experts on hand.
Topics relating to that are welcome.
During the memory handling brainstorming session earlier this year we also
touched on creating some sort of a generic buffer model allowing for easy
exchange between v4l buffers, framebuffers, texture buffers, etc. It is my
opinion that we should not discuss this in Helsinki. The list of topics is
already quite long and I think it is too early to start working on that. We
probably need another brainstorming session first in order to come up with
a reasonable proposal.
Comments? Topics I missed?
Regards,
Hans
