Tentative Agenda for the November workshop

Tentative Agenda for the November workshop

[Hans Verkuil]

Hi all,

This is the tentative agenda for the media workshop on November 8, 2012.
If you have additional things that you want to discuss, or something is wrong
or incomplete in this list, please let me know so I can update the list.

- Explain current merging process (Mauro)
- Open floor for discussions on how to improve it (Mauro)
- Write down minimum requirements for new V4L2 (and DVB?) drivers, both for
  staging and mainline acceptance: which frameworks to use, v4l2-compliance,
  etc. (Hans Verkuil)
- V4L2 ambiguities (Hans Verkuil)
- TSMux device (a mux rather than a demux): Alain Volmat
- dmabuf status, esp. with regards to being able to test (Mauro/Samsung)
- Device tree support (Guennadi, not known yet whether this topic is needed)
- Creating/selecting contexts for hardware that supports this (Samsung, only
  if time is available)

For those whose name is behind a topic: please prepare something before the
meeting.

We have currently 17 or 18 attendees of a maximum of 25, so there is room
for a few more people.

Regards,

	Hans

Thank you Hans for taking care of the agenda.

This last topic will likely require lots of brainstorming, and thus time. If 
the schedule permits, would anyone be interested in meeting earlier during the 
week already ?

My intention was to also possibly discuss it with others before the actual
media workshop. Would be nice if we could have arranged such a meeting.
I'm not sure about the room conditions though. It's probably not a big issue,
unless there is really many people interested in that topic.

Hi all,

Could someone summaries very rapidly what is this create/select context stuff ? For now I do not plan to be in Barcelona more than 1 day but at the same time don't want to miss something that might be useful for us.

Alain

Please see this thread for more details:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg52168.html

This is about creating, selecting device configuration contexts and
handling e.g. camera modes like viewfinder and still capture.
Currently only mem-to-mem devices in V4L2 API are allowed to support
multiple device contexts, and those are per file handle.

I hope this clarifies it a bit for you.

A small room with a projector would be nice if possible, although not 
required. Who would be interested in attending a brainstorming session on 
contexts ?

I would be, but the problem is that the conference is also interesting.
The only day I have really available is the Friday *after* the summit.

I'd also be interested to participate.

+ asynchronous probing, I guess. It's probably implicitly included though.

More interesting than a brainstorming session about hardware contexts ? ;-) 
There's of course talks I want to attend, but I can probably skip some of 
them.

We'll probably need several brainstorming sessions anyway. I'd like to 
organize one before the media summit though, as we'll have limited time to 
discuss the topic during the summit, which doesn't suit brainstorming sessions 
very well.

Sylwester, would Samsung be able to prepare for a brainstorming session on
Monday or Tuesday? Both Laurent and myself have presentations on Wednesday,
so that's not the best day for such a session.

Do you think we should do a half-day or a full day session on this?

Half a day should be more than enough to start with. The topic is quite 
complex, and we'll need to sleep over it, several times. A full day would just 
result in brain overheat. I was thinking more in the line of starting our 
thought process, so maybe twice an hour or two hours would be good. That would 
allow us to attend the ELCE talks as well :-) (there's definitely a couple of 
them that I would like to listen to).

I agree, I wouldn't like to loose whole day of the conference for that
as well. One, two hours for the starters could be sufficient. So we can
possibly agree on some initial idea and could get back to it later.
I don't think I have already material for a full day session.

One hour, possibly twice, would have my preference. That shouldn't be too

I've tried to get a small room for Monday, but they were all gone, so we will
have to find some other place in the hotel.

I have an extra theme for discussions there: what should we do with the drivers
that don't have any MAINTAINERS entry.

It probably makes sense to mark them as "Orphan" (or, at least, have some
criteria to mark them as such). Perhaps before doing that, we could try
to see if are there any developer at the community with time and patience
to handle them.

This could of course be handled as part of the discussions about how to improve
the merge process, but I suspect that this could generate enough discussions
to be handled as a separate theme.

There are some issues by not having a MAINTAINERS entry:
	- patches may not flow into the driver maintainer;
	- patches will likely be applied without tests/reviews or may
	  stay for a long time queued;
	- ./scripts/get_maintainer.pl at --no-git-fallback won't return
	  any maintainer[1].

[1] Letting get_maintainer.pl is very time/CPU consuming. Letting it would 
delay a lot the patch review process, if applied for every patch, with
unreliable and doubtful results. I don't do it, due to the large volume
of patches, and because the 'other' results aren't typically the driver
maintainer.

An example of this is the results for a patch I just applied
(changeset 2866aed103b915ca8ba0ff76d5790caea4e62ced):

	$ git show --pretty=email|./scripts/get_maintainer.pl
	Mauro Carvalho Chehab <mchehab@infradead.org> (maintainer:MEDIA INPUT INFRA...,commit_signer:7/7=100%)
	Hans Verkuil <hans.verkuil@cisco.com> (commit_signer:4/7=57%)
	Anatolij Gustschin <agust@denx.de> (commit_signer:1/7=14%)
	Wei Yongjun <yongjun_wei@trendmicro.com.cn> (commit_signer:1/7=14%)
	Hans de Goede <hdegoede@redhat.com> (commit_signer:1/7=14%)
	linux-media@vger.kernel.org (open list:MEDIA INPUT INFRA...)
	linux-kernel@vger.kernel.org (open list)

According with this driver's copyrights:

 * Copyright 2008-2010 Freescale Semiconductor, Inc. All Rights Reserved.
 *
 *  Freescale VIU video driver
 *
 *  Authors: Hongjun Chen <hong-jun.chen@freescale.com>
 *	     Porting to 2.6.35 by DENX Software Engineering,
 *	     Anatolij Gustschin <agust@denx.de>

The driver author (Hongjun Chen <hong-jun.chen@freescale.com>) was not even
shown there, and the co-author got only 15% hit, while I got 100% and Hans
got 57%.

This happens not only to this driver. In a matter of fact, on most cases where
no MAINTAINERS entry exist, the driver's author gets a very small hit chance,
as, on several of those drivers, the author doesn't post anything else but
the initial patch series.

Mauro

As the meeting approaches, it would be good to have a decision - do we 
want to discuss DT / async or not? My flights this time are not quite long 
enough to prepare for the discussion on them;-)

Do we have a 'Maintainer-Light' category? I have a lot of hardware that I can
test. So while I wouldn't like to be marked as 'The Maintainer of driver X'
(since I simply don't have the time for that), I wouldn't mind being marked as
someone who can at least test patches if needed.

We probably need to have an entry for all the media drivers, even if it just
points to the linux-media mailinglist as being the 'collective default maintainer'.

A MAINTAINERS entry should probably be required as well for new drivers.

Looking at the current discussions I think discussing possible async solutions
would be very useful. The DT implementation itself seems to be OK, at least I
haven't seen any big discussions regarding that.

There are several "maintainance" status there: 

	S: Status, one of the following:
	   Supported:	Someone is actually paid to look after this.
	   Maintained:	Someone actually looks after it.
	   Odd Fixes:	It has a maintainer but they don't have time to do
			much other than throw the odd patch in. See below..
	   Orphan:	No current maintainer [but maybe you could take the
			role as you write your new code].
	   Obsolete:	Old code. Something tagged obsolete generally means
			it has been replaced by a better system and you
			should be using that.

(btw, I just realized that I should be changing the EDAC drivers I maintain
 to Supported; the media drivers I maintain should be kept as Maintained).

I suspect that the "maintainer-light" category for those radio and similar
old stuff is likely "Odd Fixes".

Yes, I think that all media drivers should be there. I prefer to tag the ones
that nobody sends us a MAINTAINERS entry with "Orphan", as this tag indicates
that help is wanted.

Agreed.

That was my impression too, the bindings itself look fine in general.
At least basic features of hardware are now covered, the not very common
ones might be easily covered later when needed. 

I did an initial implementation for the s5p-fimc driver, with an I2C/SPI 
sensor subdev, based on current DT bindings and the (slightly modified) 
v4l2-of helpers. Relying only on the deferred probing mechanism and not 
using the notifiers.

It's relatively simple and works without that much changes comparing to 
the previous non-dt version. Still there are possible races when subdevs 
are loadable modules. However, the non-dt version has also problems in 
this respect, as I misinterpreted in the past the get_driver()/put_driver() 
functions [1]. So that needs to get fixed somehow to make the modules usage 
reliable.

I wrote a small shell script to see what's missing, using the analyze_build.pl script
at media-build devel_scripts dir:

	DIR=$(dirname $0)

	$DIR/analyze_build.pl --path drivers/media/ --show_files_per_module >/tmp/all_drivers
	grep drivers/media/ MAINTAINERS | perl -ne 's/F:\s+//;s,drivers/media/,,; print $_ if (!/^\n/)' >maintained
	grep -v -f maintained /tmp/all_drivers |grep -v -e keymaps -e v4l2-core/ -e dvb-core/ -e media.ko -e rc-core.ko -e ^#| sort >without_maint

I excluded the core files from the list, as they don't need any specific entry. RC
keymaps is also a special case, as I don't think any maintainer is needed for them.

Basically, analyze_build.pl says that there are 613 drivers under drivers/media.
The above script shows 348 drivers without an explicit maintainer. So, only 43%
of the drivers have a formal maintainer.

Yet, on the list below, I think several of them can be easily tagged as
"Odd fixes", like cx88 and saa7134. 

I think I'll send today a few RFC MAINTAINERS patches for some stuff below that
I can myself be added as "Odd fixes". Yet, I would very much prefer if someone
with more time than me could be taking over the "Odd fixes" patches I'll propose.

Mauro

OK. Could you please send patches for those? I think that the better is
to write one patch by each MAINTAINERS entry (except, of course, if there
are consecutive entries), as I suspect that MAINTAINERS is likely one
of top-rated merge-conflicts file.

While I don't mind if you want to do odd fixes for this device,
I think I can maintain this one, as the "default" device I use for
random tests has this chipset (HVR-950), and I wrote this driver.

I think we should check if the driver author is not interested on
taking maintainership for this one, before putting it on Odd fixes status.

Just submitted an RFC patch for this one, also as "Odd fixes".
Of course, I don't mind if you prefer to take it. Btw, you forgot
the tm6000-dvb driver, that it is part of it.

RE: [media-workshop] drivers without explicit MAINTAINERS entry - was: Re: Tentative Agenda for the November workshop

[Palash Bandyopadhyay]

Thanks Hans and Mauro.

  On any of the CX drivers, if we do not have any "maintainer" or "odd fixer", you could add me to the "odd fixer" list.

OK. Could you please send patches for those? I think that the better is to write one patch by each MAINTAINERS entry (except, of course, if there are consecutive entries), as I suspect that MAINTAINERS is likely one of top-rated merge-conflicts file.

While I don't mind if you want to do odd fixes for this device, I think I can maintain this one, as the "default" device I use for random tests has this chipset (HVR-950), and I wrote this driver.

I think we should check if the driver author is not interested on taking maintainership for this one, before putting it on Odd fixes status.

Just submitted an RFC patch for this one, also as "Odd fixes".
Of course, I don't mind if you prefer to take it. Btw, you forgot the tm6000-dvb driver, that it is part of it.

[PATCH] firedtv: add MAINTAINERS entry

[Stefan Richter]

There is currently discussion to add MAINTAINERS records for media
drivers that don't have one yet, possibly with 'orphan' or 'odd fixes'
status.  Here is a proper entry for the firedtv driver (for 1394
attached DVB STBs and 1394 attached DVB cards from Digital Everywhere).

The L: linux-media and T: linux-media.git lines in this entry are
redundant to what scripts/get_maintainer.pl would show automatically but
I added them for folks who read MAINTAINERS directly.  The "(firedtv)"
string is for those folks as well if they look for driver name rather
than file path.

The F: drivers/media/firewire/ pattern and the "FireWire media drivers"
title are currently synonymous with firedtv.  If more drivers get added
there, this can be revisited.

I don't have documentation or DVB-S2 devices to test, but I have DVB-C
and DVB-T devices for testing.

These are 'Maintained' by me:

i2c/aptina-pll.ko              = i2c/aptina-pll.c
i2c/mt9p031.ko                 = i2c/mt9p031.c
i2c/mt9t001.ko                 = i2c/mt9t001.c
i2c/mt9v032.ko                 = i2c/mt9v032.c

I can maintain the following driver if needed:

i2c/mt9m032.ko                 = i2c/mt9m032.c

I could also take over maintenance the following driver, but I don't have 
access to a hardware platform that uses it:

i2c/mt9v011.ko                 = i2c/mt9v011.c

These are, as far as I know, co-maintained by Sakari and me :-)

i2c/adp1653.ko                 = i2c/adp1653.c
i2c/as3645a.ko                 = i2c/as3645a.c

Care to send us a patch with the above? It is likely better to have one entry per
driver, to reduce the risk of merge conflicts upstream.

I'm very sorry for long silence but i'm ready to take maintainership
for radio-mr800. By the way, i think that only fixes will be present
for this driver in the future.

Is it possible for driver to have two maintainers or for example one
person marked as maintainer and another one marked as "odd fixes" ? I
mean i'm interested to be in c/c regarding all email, news,
interesting patches for radio-mr800, dsbr100 and usb radio part of
si470x but i don't know how to mark it that i want to help with these
drivers. I have only dsbr100, mr800 and kworld fm700 (based on si470x)
usb radios and i'm ready to test any patches and help as much as i
can.
I don't have usb radio for radio-keene.c driver but i probably will
take a look how to buy it here..

And i'm also ready to maintain driver radio-ma901.c. I posted patches
for this device about two weeks ago. Driver is rather small (first
working version) but i hope to add more features there in future.

Best regards and wishes,
Alexey Klimov

Good. could you please send us a patch for Maintainers then?

Well, it is possible to have two maintainers for a driver. A few of them
have it, but, AFAIKT, the driver maintainership status should be just one 
for the entire driver.

If the above drivers have a maintainer, the patch adding you there
as another maintainer should be sent by him (or with his ack).

Ok. Please send us a maintainership patch for it as well.

Thank you!

Do you plan to send a MAINTAINERS patch for this driver (and thus maintain the 
driver :-)), or should I maintain it ?

I saw that you made a MAINTAINERS entry for radio-mr800, but not for dsbr100
or si470x. Do you want to be the maintainer for those two, or shall I add
myself as the 'Odd Fixes' entry? I have hardware for both.

I wrote the driver for that one, so I'll be the maintainer for this driver
(I'm preparing MAINTAINERS patches as I write this).

I missed this post, I'll try to do a quick review today.

Did you run v4l2-compliance on this driver? If not, then you should do that
(v4l2-compliance -r /dev/radioX) and fix any errors it produces.

About si470x. It consists of two parts (usb and i2c interfaces) if i
remember correctly.
I have kworld fm700 usb radio only. I saw platforms with
radio-si470x-i2c but never had chances to play with it.
May be it's also better to ask Tobias and Joonyoung Shim.
I don't think that i'm ready to maintain si470x driver but i'll be
happy to be up to date with any changes and discussions about all usb
radio drivers.

I have usb gemtek radio 21 (dsbr100) and i'm ready to maintain it. I
can prepare patch.
Also i think that only fixes and corrections will be present for this
driver in future.

Oh, i never mean to take maintainership on keene radio (you're the author) :)
I just thought how to buy it.

No, i didn't know about this tool.
Thanks. I'll run v4l2-compliance on /dev/radio and check.

I'm happy to maintain the usb part and do odd-fixes for the i2c part for
this driver...

...and if you can maintain this driver, then we've split it up nicely.

Is that OK with you?
