I finished saa7134 part of SPI. Please review saa7134-spi.c and diff saa7134-core and etc. I wrote config of SPI to board structure. Use this config for register master and slave devices. SPI other then I2C, do not need call request_module. Udev do it. I spend 10 days for understanding :( I need help with v4l2-common.c -> function v4l2_spi_new_subdev_board The module of SPI slave loading after some time and spi device hasn't v4l2_subdev structure for v4l2_device_register_subdev. Now I get kernel crash when call v4l2_device_register_subdev. Need use a callback metod or other. I don't know. Copy to Mauro Carvalho Chehab and mailing lists for review my code too. Dmesg log without call v4l2_device_register_subdev.

Udev do it. > I spend 10 days for understanding :( 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.

After small time I'll finish process of initialize the encoder. Configure some register, upload two firmware for video and for audio. Configure the frontends. I have the questions. For configuring audio frontend need know samplerate of audio. saa7134 can only 32kHz saa7131/3/5 on I2S 32кГц from SIF source and 32/44.1/48 from external i.e. RCA stereo audio input. Hardcode 32kHz or need a function for determine mode of audio?? Other question. For configure VideoFrontend need know 50 or 60Hz Now I use videomode from h structure. I think more correct detect it on saa7134. What you think?? Dmesg with normal and junk debug printk.

Whether it is 50 or 60 Hz depends on the video standard that you receive via the s_std core op. Just implement that and when you get a new standard you can use something like this: is_60hz = (std & V4L2_STD_525_60) ? 1 : 0; Some more review comments: linux/drivers/media/video/saa7134/saa7134.h: @@ -355,6 +377,10 @@ unsigned char empress_addr; unsigned char rds_addr; + /* SPI info */ + struct saa7134_software_spi spi; + struct spi_board_info spi_conf; Make this a struct spi_board_info *.

In your case need move spi_board_info to SPI part of code. We will mix code and data. For add new cards and devices need edit some files for add configs.

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 -- Devin J.

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 Dean ^ permalink raw reply [flat|nested] 14+ messages in thread
