 In the case of this patch series, the complains are not related to 80 cols:

 In this case, there was a mix of 80-column issues, as well as some
 other issues. 

Yes, there are a few 80-column warnings but those are minor issues.
On several cases, fixing such warnings is bad.

 I did fix the issues other than the 80-column issues
 through patches added to the tree last night (and in fact I did fix
 all the 80 column issues in my actual changes - but did not fix 80
 column issues that happened to appear in the diff but were
 pre-existing).
 
 Please let me know if you have any other issues.

Provided that you've fixed the points that Takashi rised about the alsa
part, I'm fine. Please send a separate pull request c/c him , in order
to allow him to send his ack.

Cheers,
Mauro.

  Just a very quick look through the files, here are some comments:

   error).
 
  - Specifying both SNDRV_PCM_RATE_CONTINOUS and _KNOT to

   only 48kHz, SNDRV_PCM_RATE_48000 there instead.
 
  - vfree() should be called in hw_free callback rather than close
   callback.  And, there are already global vmalloc-buffer helper
   functions in the latest ALSA tree for 2.6.34...
 
  - It'd be nice if you give TLV information for the mixer dB mapping.
 
 Hello Takashi,
 
 Thanks for taking the time to provide feedback.  I will make these
 changes and add them to the tree.
 
 Out of curiosity, is there any sort of tool/code which exercises the
 driver to verify the advertised capabilities.  Part of the problem
 here is that it is not really easy to find example applications which
 use all the features, which I suspect is one of the big headaches that
 the PulseAudio people are suffering from in that they are finding bugs
 in ALSA drivers because they are the first ones to actually attempt to
 use some of these capabilities.  For me the card works, but then
 some user complains that their PulseAudio is broken because I didn't
 setup the config structures properly or only half-implemented some
 capability used by PulseAudio but not arecord/aplay.

Yeah, the test suite is one of the biggest missing pieces.
Due to its nature, the automatic test is a bit hard to achieve with
the real hardwares.

Some tools are found, however, in alsa-lib/test directory.  For example,
pcm.c can test different PCM access methods.

Before the update, v4l-dvb driver worked fine, and now it doesn't work
even if I remove the updated packages.
Checking for kernel modules conflict, I found only the modules
installed by v4l-dvb sources.

Which could be the reason of readreg error?

Subject: [PATCH - v2 1/6] V4L - vpfe capture - header files for ISIF driver

From: Muralidharan Karicheri m-kariche...@ti.com

Updated based on comments against v1 of the patch

This is the header file for ISIF driver on DM365.  ISIF driver is
equivalent
to CCDC driver on DM355 and DM644x. This driver is tested for
YUV capture from TVP514x driver. This patch contains the header files
required for
this driver. The name of the file is changed to reflect the name of IP.

My guess is that these files were provided by your distro through a
kernel update (and in 2.6.31 this board is known to have problems
which have been fixed in the latest v4l-dvb tree).

I would suggest the following going into your v4l-dvb tree and doing
the following:

make distclean  make  make install  reboot

And see if the problem clears up.

tt s2-3200: dvb-s2 problem transponders fixed :) concerns SR 30000 3/4 8psk mode

2009-12-22 Thread Newsy Paper 
thanks to Andreas Regel + Manu Abraham for their work.

I just tested those problem transponders. If I set SR to 29998 instead of 3 
they finally work with recent s2-liplian changeset.

Thank you for your great work and thanks to all the others involved in v4l 
driver development.

kind regards


Newsy

Re: How to make a Zaapa LR301AP DVB-T card work

2009-12-22 Thread Antonio Marcos López Alonso 

 
 Antonio,
 
 the report for tda10046 firmware loading is missing. Was that OK?

Yes:

tda1004x: setting up plls for 48MHz sampling clock
tda1004x: found firmware revision 29 -- ok

 
 LR301 is a LifeView design. It is very common to see multiple other
 subvendors for their cards, but they keep the original subdevice ID.
 In this case 0x0301. The subvendor 0x4e42 is usually Typhoon/Anubis and
 they are distributing clones of almost all LifeView cards.
 
 Gpio init is the same like on the other known LR301 cards and eeprom
 differs only for a few bytes, but not for tuner type, tuner and demod
 address.
 
 http://ubuntuforums.org/archive/index.php/t-328140.html
 
 Since this design with a saa7134 chip and tda8274 DVB-T only tuner is very
  old, I don't expect an additional Low Noise Amplifier on it.
 
 We can't detect such LNAs and on newer cards they can cause problems, if
 not configured correctly and might cause scan to fail.
 
 If you mean above other card types did previously work for your card,
 use them and report.

No, I meant other physical cards. Just to ensure it is not likely to be an 
aerial problem.

 
 Sorry, I don't have better ideas for your card so far.

I have not included the tuner parameter in the options line which I think 
it could be the problem. Is this parameter mandatory? If so, which is the 
proper one?

Cheers,
Antonio

 My guess is that these files were provided by your distro through a
 kernel update (and in 2.6.31 this board is known to have problems
 which have been fixed in the latest v4l-dvb tree).

 I would suggest the following going into your v4l-dvb tree and doing
 the following:

 make distclean  make  make install  reboot

 And see if the problem clears up.

This is just I have done after removing the update packages (all
related to v4l libs and tools, none related to opensuse kernel), but
with no luck

However I have just tried what you suggested, but the problem hasn't
been cleared up

[RFC v2 0/7] V4L2 file handles and event interface

2009-12-22 Thread Sakari Ailus 

Hi,

Here's the second version of the V4L2 file handle and event interface 
patchset. Still RFC since I'd like to get more feedback on it.


The first patch adds the V4L2 file handle support and the rest are for 
V4L2 events.


The patchset works with the OMAP 3 ISP driver. Patches for OMAP 3 ISP 
are not part of this patchset but are available in Gitorious (branch is 
called events):


git://gitorious.org/omap3camera/mainline.git event

The major change since the last one v4l2_fh structure is now part of 
driver's own file handle. It's used as file-private_data as well. I did 
this based on Hans Verkuil's suggestion. Sequence numbers and event 
queue length limitation is there as well. There are countless of smaller 
changes, too.


A few notes on the patches:

- I don't like the locking too much. Perhaps the file handle specific 
lock (events-lock) could be dropped in favour of the lock for 
v4l2_file_handle in video_device?


- Poll. The V4L2 specifiction says:

When the application did not call VIDIOC_QBUF or
VIDIOC_STREAMON yet the poll() function succeeds, but sets the
POLLERR flag in the revents field.

  The current events for OMAP 3 ISP are related to streaming but not 
all might be in future. For example there might be some radio or DVB 
related events.


- Sequence numbers are local to file handles.

- Subscribing V4L2_EVENT_ALL causes any other events to be unsubscribed.

- If V4L2_EVENT_ALL has been subscribed, unsubscribing any one of the 
events leads to V4L2_EVENT_ALL to be unsubscribed. This problem would be 
difficult to work around since this would require the event system to be 
aware of the driver private events as well.


- If events are missed, the sequence number is incremented in any case. 
This way the user space knows events have been missed.


Comments would be very, very welcome.

Cheers,

[RFC v2 5/7] V4L: Events: Limit event queue length

2009-12-22 Thread Sakari Ailus 
Limit event queue length to V4L2_MAX_EVENTS. If the queue is full any
further events will be dropped.

This patch also updates the count field properly, setting it to exactly to
number of further available events.

[RFC v2 4/7] V4L: Events: Add backend

2009-12-22 Thread Sakari Ailus 
Add event handling backend to V4L2. The backend handles event subscription
and delivery to file handles. Event subscriptions are based on file handle.
Events may be delivered to all subscribed file handles on a device
independent of where they originate from.

[RFC v2 1/7] V4L: File handles

2009-12-22 Thread Sakari Ailus 
This patch adds a list of v4l2_fh structures to every video_device.
It allows using file handle related information in V4L2. The event interface
is one example of such use.

Video device drivers should use the v4l2_fh pointer as their
file-private_data.

Re: tt s2-3200: dvb-s2 problem transponders fixed :) concerns SR 30000 3/4 8psk mode

2009-12-22 Thread Emmanuel 

Newsy Paper a écrit :

thanks to Andreas Regel + Manu Abraham for their work.

I just tested those problem transponders. If I set SR to 29998 instead of 3 
they finally work with recent s2-liplian changeset.

Thank you for your great work and thanks to all the others involved in v4l 
driver development.
  
Then I guess this is related to a computation being abit off (3 is 
probably a threshold also).
I any case I still have to add 4MHz to the frequencies (with DVB-S) to 
get a reliable lock with tt s2-3200 (kernel is ubuntu 2.6.31.4)

Bye
Manu

Hello Purush,

Sorry for the delay. We know that some webcams with Z-Star chips have
such a problem, but it is a hardware problem and we did not find yet a
way to fix it correctly...

Re: How to make a Zaapa LR301AP DVB-T card work

2009-12-22 Thread hermann pitton 

Am Dienstag, den 22.12.2009, 16:41 + schrieb Antonio Marcos López
Alonso:
  
  Antonio,
  
  the report for tda10046 firmware loading is missing. Was that OK?
 
 Yes:
 
 tda1004x: setting up plls for 48MHz sampling clock
 tda1004x: found firmware revision 29 -- ok
 
  
  LR301 is a LifeView design. It is very common to see multiple other
  subvendors for their cards, but they keep the original subdevice ID.
  In this case 0x0301. The subvendor 0x4e42 is usually Typhoon/Anubis and
  they are distributing clones of almost all LifeView cards.
  
  Gpio init is the same like on the other known LR301 cards and eeprom
  differs only for a few bytes, but not for tuner type, tuner and demod
  address.
  
  http://ubuntuforums.org/archive/index.php/t-328140.html
  
  Since this design with a saa7134 chip and tda8274 DVB-T only tuner is very
   old, I don't expect an additional Low Noise Amplifier on it.
  
  We can't detect such LNAs and on newer cards they can cause problems, if
  not configured correctly and might cause scan to fail.
  
  If you mean above other card types did previously work for your card,
  use them and report.
 
 No, I meant other physical cards. Just to ensure it is not likely to be an 
 aerial problem.

Good to know. However, the first revisions of silicon tuners like the
tda8274 can't compete with can tuners. Only the tda8275a hybrid can come
_close_ to a good can tuner like the FMD1216ME/I H-3 (MK3) on a well
designed PCB. Signal quality might be still not sufficient for your
card.

You also had parity errors on your first report, which likely indicate
problems on your mobo at least with this PCI slot and/or sharing
interrupts with other devices there.

  Sorry, I don't have better ideas for your card so far.
 
 I have not included the tuner parameter in the options line which I think 
 it could be the problem. Is this parameter mandatory? If so, which is the 
 proper one?
 

No. You can force tuner types only for analog TV. The tda8274 is not a
hybrid tuner, it is only used for DVB-T. An early tda8275 hybrid with a
saa7134 chip would have a separate tda8290 chip for analog IF
demodulation. Without that no analog TV and no tuner type to set.

For DVB-T the tda8274 is treated like a tda8275.

Cheers,
Hermann

I moved to Mandriva 2009.1, then 2010.0 (kernel 2.6.31.6) and it 
doesn't work well any more. Scan can't find channels. I tried hading 
options dvb-usb-dib0700 force_lna_activation=1 in 
/etc/modprobe.conf. It improve just a bit. Scan find only a few 
channels. If I revert to Mandriva 2008.1 (in another partition), all 
things are good (without adding anything in modprobe.conf).


Is there a new version of the driver (dvb_usb_dib0700) that correct 
this behavior.
If not, how to install the driver from kernel 2.6.24.7 in kernel 
2.6.31.6 ?




Please try the current driver available at v4l/dvb develpment tree and 
share your results here.


hg clone http://linuxtv.org/hg/v4l-dvb
make
make rmmod
make install

Finally, just restart your machine and test your favourite application.
