Hi All,

We have set aside the second day of the kernel summit (Tuesday 28
August) as mini-summit day.  So far we have only the PCI mini summit on
this day, so if you can think of other topics, please send them to the
kernel summit discuss list:

ksummit-2012-discuss@lists.linux-foundation.org

Looking at the available rooms, we think we can run about four or five
mini summits.

As an added incentive, mini summit organisers get to pick who they
invite and all the people they pick will get an automatic invitation to
the third day of the kernel summit (but not the core first day) and the
evening events.

James

There is a lot of interest in having another ARM mini-summit, as we had last
year. Previously, Grant Likely organized this with Olof and me, but right now
Grant is in an extended offline period and Olof is currently on vacation
as well. Will Deacon already contacted me and he is interested in helping
out with organizing the mini-summit, so the two of us could be the primary
contacts, with Grant and Olof joining in as time permits.

I'm planning to send out an initial email to potential participants today
or tomorrow to get an idea of who would be joining. Do you have an upper
limit to the number of people that you expect a mini-summit? I think we
could easily get 30 or more people that want to come, but we can also
restrict it to a smaller size.

Same here. The previous incarnation of the mini-summit was very
successful, and I would be very interested in attending another one.

It's not like we're having any shortage of things to discuss these days...

I would be interested in attending it as well. I believe Stefano has a strong
interest as well (since he and Ian Campbell are leading the Xen ARM work).

Is there enough interest to have a networking mini-summit?

It looks like there are some key wireless developers that will be
available in San Diego.  At least one of them (Johannes) will _not_
be available for the planned wireless mini-summit event later in
Barcelona.  So, it would be valuable for the wireless folks to have
an opportunity for a confab in San Diego.

If there are a plethora of mini-summits proposed, this one should be
low priority.  As mentioned, we already have something planned for
later in the year.

And Stefano is out on vacation right now so I will serve as his phantom voice
and say: "Yes, I am interested as well."

Ok. So are you mostly interested in discussion ARM virtualization or other topics
as well? Last time we had organized this explicitly as the "ARM subarch maintainer
summit" and we might again limit the participants to the subarch maintainers and
a few more people if we're running out of space, but then again if a lot of them
are interested in discussion virtualization, we should probably have you both and 
the ARM KVM people included as well.

We haven't even started discussing an agenda, but I'll note down your names as
candidates and Xen and/or KVM as proposed topics. I'll follow up with a more
formal call for topics once I have a positive confirmation from James and the
linux-foundation that we can go ahead with the ARM mini-summit.

More on the virtualization side. If you are getting close to no space, take me
off the roll but please include Stefano on it.

I found the ARM mini-summit last year to be valuable.  I'm definitely
interested.

Because of the location, I think there should be a good turnout of
Qualcomm kernel devs at plumbers, if anyone wants to meet anyone,
that'd be a good time.

Putting on my KVM/ARM hacker hat this time: I'd be very glad to contribute
to the discussion. There is a number of ARM-specific topics that would be
interesting to discuss regarding KVM/ARM (mainlining the damn thing, common
hypercalls?, HYP mode booting), and probably a couple of other things.

Cheers,

Perhaps a mini-summit on ARM virtualization, too? Xen Summit is also
co-located.

Not sure what happened (or maybe my proposal were not clear enough), but 
I've submitted a proposal to have a media system summit on KS/2011.
Last year was very productive for media developers, so we'd like to do
it again ;)

[Ksummit-2012-discuss] [ATTEND] media subsystem

I'd like to have media subsystem discussions this year's at kernel summit. 
The media subsystem is one of the most active driver subsystem, and there are lots of 
things there that require face-to-face discussions, not only between subsystem developers, 
but also with other maintainers. In special, during KS/2011, it was identified the need 
of interacting with video and audio system people, in order to solve some common issues, 
like HDMI CEC and audio/video synchronization. 

The increasing complexity of SoC designs used by media devices requires API
extensions at the media APIs in order to proper expose and control all hardware 
functionality on a standard way. A new API to better allow negotiating userspace
and Kernelspace capabilities seem to be required.

More discussions with regards to shared resources locking is needed, on devices that
implement multiple API's, but not a the same time.

The incompatibility between udev-182 and the existing drivers will also require lots
of discussions, as that affects 64 media drivers, and changing them to comply with
the current requirement of using request_firmware_nowait() won't work on several
drivers. So, a solution (or a set of solutions) needs to be found, in order to fix
such incompatibility.

Thanks,
Mauro

I'd like to add a "Common device tree bindings for media devices" topic to
the agenda for consideration.

There were some activities on creating device tree bindings for Samsung and
SH Mobile SoCs but this didn't really kick off yet and a face to face discussions
could help to bring device tree support in media subsystem to the level many
other subsystems already have.

That's right: the hypercall calling convention, notifications from the
hypervisor via GIC, the boot process and device tree for virtual
hardware are all interesting topics to discuss.

There's a handful of various subsystems that have similar topics,
maybe slice it the other way and do a device-tree/ACPI breakout that
cuts across the various areas instead?

Communication really needs to be two-way: Crafting good bindings for a
complex piece of hardware isn't trivial and having someone know both
the subsystem and device tree principles is rare. At least getting all
those people into the same room would be good.

There's obvious overlap with ARM here as well, since it's one of the
current big pushers of DT use, but I think it would be better to hold
this as a separate breakout from that.

I'm not so sure: I think that most decisions that need to be made are
quite subsystem specific. Trying to figure out how to implement DT for
multiple subsystems in one workshop seems unlikely to succeed, simply
because of lack of time. I also don't think there is much overlap between
subsystems in this respect, so while the DT implementation for one subsystem
is discussed, the representatives of other subsystems are twiddling their
thumbs.

It might be more productive to have one or two DT experts around who
rotate over the various workshops that have to deal with the DT and can
offer advice.

I'm sure everyone has seen this, but just to have it mentioned here:

<a 
href="http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/50755">
shameless self-advertisement</a>

I'm not sure whether the overlap with other subsystems is large or not, 
but there definitely is some, also with video (fbdev / drm), e.g., 
http://thread.gmane.org/gmane.linux.drivers.devicetree/17495

As for whether or not discuss DT for various subsystems together - why not 
do both? First short sessions in each subsystems, of course, this would 
only work if proposals have been prepared beforehand and at least 
preliminary discussions on the MLs have taken place, and then another 
(also short) combined session? Of course, it also depends on how much time 
we can and want to dedicate to this.

I hadn't seen it, since you didn't cc devicetree-discuss. Well, I'm
also generally behind on list email right now since I am travelling
but I couldn't find it in any list folder I subscribe to.

The agenda for such a day should probably be partially broken down per
subsystem, yes, and it would make sense for people from the various
areas to describe the kind of setup that they need to be able to
define, similar to how you did in your writeup above.

In some cases it would be a matter of in-person
review/discussion/arguments of already proposed bindings, in other
cases it would probably be a seeding discussion for upcoming bindings
instead. Having the latter piggy-back on hearing what's discussed with
the former category would likely be a good idea.

OK, so far I believe I've heard concrete suggestions from identified
(or fairly well identified :-) stuckees willing to organize
mini-summits for:

* ARM
* Media
* PCI
* memcg

I may have missed some, so if people could send a message to the
discuss list with [MINI-SUMMIT] in the subbject line and the name of
the proposed mini-summit, that would be really helpful.  Please
indicate whether you are volunteering to help organize the proposed
mini-summit, or identify someone you think can be volunteered.  :-)

Things that we will be asking the mini-summit chars to determine, in
addition to who should be given invites for Tuesday and Wednesday is
an estimate of how much time you need, and a list of sub-topics (and
who might lead the sub-topic discussion).  We will be asking you to
create a fairly well-defined schedule, with 30 and 60 minute slots, so
that we can publish a schedule and so that people who might need to
hop between mini-summits, have a chance to do so.  So please start
thinking about how long each of your sub-topics will need to be, and
who might be needed for a particular sub-topic's discussion to be
successful.  There may be a number of developers, with fingers in
multiple subsystem, where scheduling may become a bit of a challenge.

Thanks!!

As we did in 2012, we're planning to do a media summit again at KS/2012.

The KS/2012 will happen in San Diego, CA, US, between Aug 26-28, just
before the LinuxCon North America.

In order to do it, I'd like to know who is interested on participate,
and to get proposals about what subjects will be discussed there,
in order to start planning the agenda.

Thanks!
Mauro

I'm interested. I like the idea of some cross-subsystem pollination,
talking with the ALSA people for example ... and given that ARM is
growing, I'd like to catch up and understand where ARM silicon is
heading in terms of embedded video decoding and any support for
hardware specific features we may / may not have / need.

... and of course, if we have anyone from Intel then we should be
asking if/when their Intel Media SDK (hardware H264  encoding) is
going to become a reality, or possibly kickstart that process.

I'd like to have 30 minutes to discuss a few V4L2 API ambiguities or just
plain weirdness, just like I did last year. I'll make an RFC issues to discuss
beforehand. I might also have a short presentation/demo of v4l2-compliance, as
I believe more people need to know about that utility.

That's a good idea. On the topic of ambiguities, could you add VIDIOC_STREAMON 
and VIDIOC_STREAMOFF behaviour when the stream is already started/stopped 
respectively ?

I'd love to attend, especially since, as you have seen, I've started doing 
some work on V4L DT bindings, but so far it very much looks like I won't 
be able to do so unfortunately.

That's very much in line with the KS/LPC spirit, I'd like to see that happen 
as well. We've been talking about media controller support in ALSA for ages 
:-)

Information about future directions is unfortunately usually private, but we 
can always ask. To be honest I sometimes feel like even SoC vendors themselves 
don't know where they're heading to :-) If only that, a presentation about the 
latest media-related hardware developments on ARM would be good to get 
everybody up to speed.

As you already know, that's a topic I'm very interested in. DT bindings will 
likely involve rethinking how the V4L2 core and V4L2 drivers instantiate 
subdevices, a media summit would have been a good occasion to discuss that. 
However, we probably need an RFC to start with.

Sakari and I will spend time on the long-awaited media controller library in a 
couple of weeks, I hope to have results to present during the summit.

Depending on the audience, I would also be interested in getting feedback from 
SoC vendors who are not (yet) active in the V4L2 community on our approach and 
how we could best help them. This could include discussions about Android, as 
I believe we need to push V4L2 on that platform. Guennadi's recent work on an 
Android V4L2 camera library is a good first step in that direction.

Hi Mauro,
Great news, please count me in. We are currently building a new
ChromeOS graphics/media stack based on V4L2, vb2, dmabuf, DRM and GL.
Synchronization/shared resource usage is one important topic for
discussion, as well as, depending on interest, perhaps optimizations
like CPU cache maintenance, dmabuf hint/caching sglists, sharing
mappings between drivers, etc. Perhaps others would also have
something to add to this list.

Thanks!
Pawel Osciak

You've certainly seen these two RFCs currently being discussed:

Sorry, I meant RFC patches. The devil (or part of it) will be in the details, 
solving race conditions and other similarly fun issues will require 
experimentation.

I still need to review that one :-)

Another ambiguity for your list: what should a driver return in TRY_FMT/S_FMT 
if the requested format is not supported (possible behaviours include 
returning the currently selected format or a default format).

Whatever gets decided in terms of eliminating the ambiguity, we should
definitely do a v4l2-compliance test for this.  I've seen drivers in
the past that return -EINVAL if the requested format is not supported
(which resulted in various userland apps inventing their own
workarounds over the years).

Things change and sometimes also to the better:-) Looks like I'll be able

Do you guys expect to discuss anything relevant to userland? (V4L? DVB? ...?)

What do you think about adding new M2M capability flag for memory-to-memory
video devices ? I prepared an RFC patch for that already:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg48497.html

I think that at least qualifies to your list of V4L2 API ambiguities, even
though we have device_caps now. Using ORed OUTPUT and CAPTURE flags implies 
all existing applications must check now both flags when they're trying to 
discover a video capture or video output device.

I agree. I've added to my list (which is getting pretty long BTW, I will
probably need more than 30 minutes).

When adding support for M2M devices to v4l2-compliance I also noticed that
using CAPTURE+OUTPUT is a rather awkward way to signal this capability, so
I agree to adding a special cap bit for that.

Regards,

	Hans

If it's of interest to anyone, I could probably present a bunch of issues with 
V4L2 and DVB from userspace perspective.

Remi,

I would strongly be in favor of this.  One thing that we get far to
little of is feedback from actual userland developers making use of
the V4L and DVB interfaces (aside from the SoC vendors, which is a
completely different target audience than the traditional V4L and DVB
consumers)

Ditto.  Input from user application developers  is something that kernel developers need and value greatly.

Note, that I will not be at the workshop of Plumbers this year. :(

Is the media summit timed with LPC or the kernel summit? If I come, I have to 
leave on Thursday to catch the VideoLAN conference in Paris on the next week-
end...

I wonder if it is wise to merge both DVB and V4L2 APIs, add needed DVB 
stuff to V4L2 API and finally remove whole DVB API. V4L2 API seems to be 
much more feature rich, developed more actively and maybe has less 
problems than current DVB API.

This may just be a case of "the grass is always greener on the other
side of the fence".  The V4L2 subsystem has more than it's share of
problems - you just don't see them since you don't work with that code
on a regular basis.

Hello Mauro,

We would like to participate in the media summit at San Diego. Can you please reserve 2 seats for us. If possible we would like to reserve a session to present how we have used the linuxTV to model our devices and support our use cases. We will also consolidate and pass on a list of questions related to spec ambiguities and hope to get it clarified during the summit!

Can you please confirm back on the feasibility of our attendance?

Regards
Naveen Krishnamurthy

As we did in 2012, we're planning to do a media summit again at KS/2012.

The KS/2012 will happen in San Diego, CA, US, between Aug 26-28, just
before the LinuxCon North America.

In order to do it, I'd like to know who is interested on participate,
and to get proposals about what subjects will be discussed there,
in order to start planning the agenda.

Thanks!
Mauro

OK, so far I believe I've heard concrete suggestions from identified
(or fairly well identified :-) stuckees willing to organize
mini-summits for:

* ARM
* Media
* PCI
* memcg

I may have missed some, so if people could send a message to the
discuss list with [MINI-SUMMIT] in the subbject line and the name of
the proposed mini-summit, that would be really helpful.  Please
indicate whether you are volunteering to help organize the proposed
mini-summit, or identify someone you think can be volunteered.  :-)

Things that we will be asking the mini-summit chars to determine, in
addition to who should be given invites for Tuesday and Wednesday is
an estimate of how much time you need, and a list of sub-topics (and
who might lead the sub-topic discussion).  We will be asking you to
create a fairly well-defined schedule, with 30 and 60 minute slots, so
that we can publish a schedule and so that people who might need to
hop between mini-summits, have a chance to do so.  So please start
thinking about how long each of your sub-topics will need to be, and
who might be needed for a particular sub-topic's discussion to be
successful.  There may be a number of developers, with fingers in
multiple subsystem, where scheduling may become a bit of a challenge.

Thanks!!

Please pass that list on to me. I'm doing the section on V4L2 spec ambiguities 
etc., so I'd like to merge all just questions in one session.

Note that my session only deals with V4L2 issues. For DVB issues someone
else would have to coordinate that.

It's timed with the kernel summit and it will be on Tuesday. So you should 
have ample time.

And feedback to us from a user perspective would be very useful. As others
have mentioned, we do not see that often enough.

Sure Hans, we will collate the spec ambiguities and pass it on to you before the meeting for you.

Please pass that list on to me. I'm doing the section on V4L2 spec ambiguities 
etc., so I'd like to merge all just questions in one session.

Note that my session only deals with V4L2 issues. For DVB issues someone
else would have to coordinate that.

Another ambiguity for your list, should video output drivers fill the sequence 
and timestamp fields when returning a v4l2_buffer from VIDIOC_DQBUF ?

Sorry again... Does that mean nothing happens on Sunday and Monday?

Also, when do get confirmed invitations to attend the media summit?

To my knowledge there is nothing planned with respect to V4L/DVB.

Monday is the closed session of the kernel summit. All workshops of the
various subsystems are scheduled on Tuesday.

That doesn't mean nothing happens: I'll be attending the gstreamer
conference on Monday myself.

> Also, when do get confirmed invitations to attend the media summit?

I'll make sure you'll be invited. I'm not even sure you need an official
invite for the workshop. I know that anyone who also attends the LPC can
get an invite for the workshops on Tuesday for free.

Anyway, I'll put your name on the list and make sure that Mauro will pass
that on to the organizers once he's back from vacation.

Regards,

	Hans

"Nothing" is a bit too strong of a word :-)

Several developers will already be present on Sunday and Monday, so it could 
be possible to already hold meetings (although getting a room might not be 
easy). You can also attend the GStreamer Conference on Monday if you wish.

> Also, when do get confirmed invitations to attend the media summit?

I expect Mauro to send them when he will be back from holidays.

Excelent idea. I'll be adding it at the topics proposal summary.

In order to sum-up the discussions around the media summit,
this is what we've got so far:

Proposals									     	proposed by
=====================================================================================|=========================================================================================
Common device tree bindings for media devices						Sylvester Nawrocki / Guennadi Liakhovetski
ALSA and V4L/Media Controller								Steven Toth / Laurent Pinchart
ARM and needed features for V4L/DVB							Steven Toth
Intel media SDK										Steven Toth
V4L compiance tool									Hans Verkuil
V4L2 API ambiguities									Hans Verkuil
Media Controller library								Laurent Pincart / Sakari Ailus
SoC Vendors feedback – how to help them to go upstream – Android's V4L2 cam library	Laurent Pincart / Guennadi Liakhovetski / Palash Bandyopadhyay / Naveen Krishnamurthy
Synchronization, shared resource and optimizations					Pawel Osciak
V4L2/DVB issues from userspace perspective						Rémi Denis-Courmont

As we'll have only one day for the summit, we may need to remove some
themes, or maybe to get an extra time during LPC for the remaining
discussions.
	
Possible attendents:
===================

Guennadi Liakhovetski
Laurent Pinchart
Mauro Carvalho Chehab
Michael Krufky
Naveen Krishnamurthy
+1 seat from ST (waiting Naveen to define who will be the other seat)
Palash Bandyopadhyay
Pawel Osciak
Rémi Denis-Courmont
Sakari Ailus
Steven Toth
Sylvester Nawrocki

Am I missing something?

Are there other proposals or people intending to participate?

Regards,
Mauro

Of course I am missing something: for the DT, ALSA and ARM proposals, we'll
need attendants from those subsystems ;)

Yes: I would like to discuss how to add support for HDMI CEC to the kernel.
In particularly I need some feedback from the GPU driver developers on what
their ideas are, since CEC is something that touches both V4L2 and GPU.

I'm not sure what the best place is to do this, it's a fairly specialized
topic. It might be better suited to just get a few interested devs together
in the evening or during some other suitable time and just see if we can
hammer out some scheme. I'll have a presentation on the topic ready.

Rob, what are your ideas on this?

Who else might be interested in this?

Regards,

	Hans

Unfortunately I won't be attending the media summit this time.
Instead, my colleagues: Bartlomiej Zolnierkiewicz and Marek Szyprowski
could cover the topic I proposed. Can you please add them to the
list of attendants instead of me ?

Hi Mauro,

For the summit this time it is be just me who would be attending. The another person who was slated to  join me cannot make it this time.

Sorry for the delay in response.

Regards
Naveen

I am not familiar with CEC implementation in GPU. But CEC should be
independent in functionality with audio/video though it is A/V
related. I prefer to support only CEC frame TX/RX in kernel. CEC
include different category features that need parsing and may need
application interaction. Venders may also configure some features as
not supported.  If kernel support more than TX/RX, policy may be
separated to user space part and kernel space part. The kernel
interface also becomes complex, maybe ambiguous too. An user space
library is more suitable for this task to interact with OS/media
player/audio control/etc.

As far as I am aware there isn't any.

I wish that were possible. Our current implementation internally is as you
proposed, but we recently discovered that for HDMI 1.4a this won't fly.

There the CEC channel is also used for control of the ethernet and audio
return channel, and even for hotplug detect in some cases.

That's something that has to be handled entirely in kernelspace. So some
parts of the CEC protocol have to be internally processed, other parts
have to be processed in userspace.

This really complicates things and it makes it even more important that
the subsystems that need CEC work together on this.

	Hans

Thanks for your reminder. I was not aware of HEAC/ARC dependence on
CEC for our product does not include these features. Maybe we can
parse CDC CEC message in kernel and leave others to user space. But it
is also an ugly propose.
BTW: Do you see any scenario that EDID is changed dynamically? I do
not know why to add hot-plug to CEC control while no physical HPD
changes.

Switching between an EDID for analog or digital input when using a DVI-I cable
is the most common use-case that I know of. But this does not apply as such to
an HDMI connector since that's digital only.

Another might be that a simple EDID is setup when the device boots, and once
it is booted and all the features of the device are known a more advanced EDID
might be written.

I'm sure that there are more creative uses as well...

Hi Mauro,

Can you please provide the schedule for the linuxTV discussions this time at San Diego? Which day will it be on? If you have a detailed schedule, please pass on. I am planning to be in only on that day as I cannot stay back more than that this time around.

Regards
Naveen

Wow, this is interesting... Have I proposed this? :-) Or is anyone else 
working on an alternative solution?... I don't mind talking about this, if 
indeed my work is meant, just really cannot remember discussing taking 
this topic to the KS... I might have forgotten though... /me confused :-)

What happened to the V4L DT topic? I believe, Sylwester and I have been 
discussing this pretty intensively over the last couple of weeks and, 
hopefully, are just about to submit an example V4L .dts fragment.

I believe it was deemed to be a too complex topic that would take too much 
time to fit in the schedule. I will be free on Monday to discuss this, should 
we organize a (informal) meeting ?

Sure, everyone is most welcome to join me on the plane;-) I should arrive 
to the airport at 18:15, so, if anyone would like to talk to me after a 
13.5-hour trip - we can try that:-)

It was proposed by someone ;) I think you said you would be giving this
talk, if I'm not mistaken, on the discussions we had. So, we're counting
on you ;)

There was some discussions about having a DT summit or BoF there, so
it was left away from the media workshop, due to the lack of time for all
panels there (and since this is really a DT-specific theme). I didn't
track if the DT workshop got actually scheduled or not.

I'm sure you'll be able to find some time along the week to do such
meeting. In my case, I don't feel I need to be on such discussions,
as this is not directly related to the media API, and such patches go
though other trees (or though media tree, but with DT maintainers
acks). Yet, I'd like to know about the end results of such discussions, 
in order to keep track of it.

Mauro

Yes, there will be a summit report. It's not quite finished yet, I think.

With respect to CEC we had some useful discussions. It will have to be a
new class of device (/dev/cecX), so the userspace API will be separate from
drm or v4l.

And the kernel will have to take care of the core CEC protocol w.r.t. control
and discovery due to the HDMI 1.4a requirements.

I plan on starting work on this within 1-2 weeks.

My CEC presentation can be found here:

Thanks for quick response! It's good to know that CEC is independent
with DRM/V4L for my HDMI implementation is FB/lcd-device based. CEC is
also deserved to have independent management in both hardware signal
and functionality. Someone also expressed similar thoughts before.
Will remote control protocal parsing are done in userspace reference
library? Or not decided yet?

Are you referring to the remote control pass-through functionality?
I don't know yet whether that will go through a userspace library or
through the RC kernel subsystem, or possibly both.

Most of the other non-system messages will go to a userspace library.

But I haven't started coding yet, so it is very early days :-)

The main thing is that at least I now have a high-level design that
I can start to work with.

I mean all the feature that can involved in handhold remote control,
one touch play, standby, on screen display, etc, such as
play/pause/poweroff. I want to mention all non CDC features that can
be implemented in user space. They are hard to be covered by any
sub-system and user space library is more proper. Just like your
metaphor, kitchen sink for CEC. I like your words.

Yes, that will all be userspace.

My plan is to have the CEC adapter driver handle the core CEC protocol,
allow other drivers to intercept messages that are relevant for them and
send messages themselves, and anything that remains will be available to
userspace for which a new library will be created.

Now, don't ask me about any of the details, since I don't have them yet :-)
My plan is to start working on this next week or the week after.

Are you willing to test early versions of this work? Can you test HDMI 1.4a
features as well? Testing this might well be one of the harder things to do.

Regards,

	Hans

I am willing to test or contribute to the library. But my hardware
does not include HEAC. So my test scope limites to the features that
can be implemented in user space.

This is a repeat of a comment from the KS discussion: what about using the 
socket API instead of a device node ?

What benefit would that give me? I frankly don't think it maps that well to
a socket API. Some parts of the CEC protocol are more or less network like,
but others are point-to-point. Basically CEC is a mess, protocol-wise, and
I much prefer a char-device where you have more flexibility.
