Hi Dmitri,

Just a quick note: the video4linux mailinglist is obsolete, just use linux-media.

I'm almost certain that spi works the same way as i2c and that means that you
must call request_module. Yes, udev will load it for you, but that is a delayed
load: i.e. the module may not be loaded when we need it. The idea behind this
is that usually i2c or spi modules are standalone, but in the context of v4l
such modules are required to be present before the bridge can properly configure
itself.

The easiest way to ensure the correct load sequence is to do a request_module
at the start.

Now, I haven't compiled this, but I think this will work:

struct v4l2_subdev *v4l2_spi_new_subdev(struct v4l2_device *v4l2_dev,
               struct spi_master *master, struct spi_board_info *info)
{
	struct v4l2_subdev *sd = NULL;
        struct spi_device *spi;
	
	BUG_ON(!v4l2_dev);

	if (module_name)
        	request_module(module_name);

	spi = spi_new_device(master, info);

	if (spi == NULL || spi->dev.driver == NULL)
		goto error;

       if (!try_module_get(spi->dev.driver->owner))
               goto error;

       sd = spi_get_drvdata(spi);

       /* Register with the v4l2_device which increases the module's
          use count as well. */

       if (v4l2_device_register_subdev(v4l2_dev, sd))
               sd = NULL;

       /* Decrease the module use count to match the first try_module_get. */
       module_put(spi->dev.driver->owner);

error:
       /* If we have a client but no subdev, then something went wrong and
          we must unregister the client. */

       if (spi && sd == NULL)
               spi_unregister_device(spi);

       return sd;
}
EXPORT_SYMBOL_GPL(v4l2_spi_new_subdev);

Note that you mixed up the spi master and spi client in your original code. So
it is no wonder you experienced crashes.

Also note that there is no need for a separate v4l2_spi_new_subdev_board function.

And in v4l2_spi_subdev_init() you should use spi_set_drvdata instead of
dev_set_drvdata.

I hope this helps.

Regards,

	Hans

Module not load successfull. As I see spi_register_driver in upd61151.c not finished a long long long time
and killed by kernel. I see this message last 10 days befor removing request_module from function.

> Note that you mixed up the spi master and spi client in your original

Yes, this is my error you are right. :((

         struct spi_device *spi;
 	
 
 	spi = spi_new_device(master, info);

> And in v4l2_spi_subdev_init() you should use spi_set_drvdata instead

Ok

Thank you.

There is one thing missing here: module_name should be passed in as argument
to v4l2_spi_new_subdev. Does this code actually compile? If so, then I suspect
module_name must be some global variable with some bogus value which causes
request_module to time out.

Remove v4l2_spi_new_subdev_board. Just have a v4l2_spi_new_subdev as in my code.

Hi J,

Is this device plugged directly into the USB port on the motherboard?
Or do you have a USB hub that the device is connected to.  Sometimes
low quality USB hubs will not work properly with high speed isoc
devices.

Also, I would suggest that you leave the device unplugged when
powering up the system.  Then once it is up, plug it in and send the
full dmesg output.  This will make it easier to analyze the dmesg
output because the driver will not be initializing at the same time as
all the other USB devices.

Also, please provide the *full* dmesg output, so we have more context
information about the system (things such as the kernel version, etc).

Cheers,

Devin

Hi,

I have the KWorld DVB-T 305U, an em28xx device.  Only the video works for me under Linux, no audio.  In case anyone wants to see it, I have attached the full dmesg text, solely from this device.

Cheers,
Dean

Hi Dean,

How are you testing the audio, and under what video standard are you
trying to use the device (NTSC/PAL/SECAM)?

I am receiving NTSC TV signals.  I test with mplayer.  Example;

mplayer tv://9 -tv driver=v4l2:alsa:immediatemode=0:adevice=hw.Em28xxAudio,0:norm=ntsc:chanlist=us-cable -vf pp=ci

The above command works fine (both audio and video) with my Hauppauge HVR-850, but for the Kworld 305U I must change 'immediatemode=0' to 'immediatemode=1' otherwise the video frame rate is about 1/2 normal speed and about 1 minute later mplayer starts printing 'video buffer full - dropping frame'.

According to dmesg the Kworld 305U loads the same firmware as my Hauppauge HVR-850, and (during separate test sessions) installs the same ALSA device;

card 1: Em28xxAudio [Em28xx Audio], device 0: Em28xx Audio [Empia 28xx Capture]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Try this:  open em28xx-cards.c, and change the board profile for the
entry EM2880_BOARD_KWORLD_DVB_305U such that it includes the following
field:

.mts_firmware = 1,

Then recompile and see if it starts working.
