In order to test capture and output overlays a simple framebuffer device is created. It's bare bone, but it does the job. Signed-off-by:

Add the kthread handlers for video/vbi capture and video/vbi output. These carefully control the rate at which frames are generated (video capture) and accepted (video output). While the short-term jitter is around the order of a jiffie, in the long term the rate matches the configured framerate exactly. The capture thread handler also takes care of the video looping and of capture and overlay support. This is probably the most complex part of this driver due to the many combinations of crop, compose and scaling on the input and output, and the blending that has to be done if overlay support is enabled as well.

This adds support for VBI capture (raw and sliced) and VBI output (raw and sliced) to the vivid driver. In addition a VBI generator is added that generates simple VBI data in either sliced or raw format. Signed-off-by:

If this is a multiplanar buf_type and the plane we want to read has a non-zero data_offset, then that data_offset was not taken into account. Note that read() or write() for formats with more than one plane is currently not allowed, hence the use of 'planes[0]' since this is only relevant for a single-plane format. Signed-off-by:

Maximum satellite symbol rate used is 45000000Sps which overflows when multiplied by 135. As final calculation result is fraction, we could use mult_frac macro in order to keep calculation inside 32 bit number limits and prevent overflow. Original bug and fix was provided by Nibble Max. I decided to implement it differently as it is now. Reported-by:

Reported by Dan Carpenter: The patch d10d1b9a: "[media] dvb_usb_v2: use dev_* logging macros" from Jun 26, 2012, leads to the following Smatch complaint: drivers/media/usb/dvb-usb-v2/dvb_usb_urb.c:31 dvb_usb_v2_generic_io() error: we previously assumed 'd' could be null (see line 29) ... Remove whole check as it must not happen in any case. Driver is totally broken if it does not have valid pointer to device. Reported-by:

TechnoTrend TT-connect CT2-4650 CI (0b48:3012) is an USB DVB-T2/C tuner with the following components: USB interface: Cypress CY7C68013A-56LTXC Demodulator: Silicon Labs Si2168-A20 Tuner: Silicon Labs Si2158-A20 CI chip: CIMaX SP2HF The firmware for the tuner is the same as for TechnoTrend TT-TVStick CT2-4400. See https://www.mail-archive.com/linux-media@vger.kernel.org/msg76944.html The demodulator needs a firmware that can be extracted from the Windows drivers. File ttConnect4650_64.sys should be extracted from http://www.tt-downloads.de/bda-treiber_4.1.0.4.zip (MD5 sum below). 3464bfc37a47b4032568718bacba23fb ttConnect4650_64.sys Then the firmware can be extracted: dd if=ttConnect4650_64.sys ibs=1 skip=273376 count=6424 of=dvb-demod-si2168-a20-01.fw The SP2 CI module requires a definition of a function cxusb_tt_ct2_4650_ci_ctrl that is passed on to the SP2 driver and called back for CAM operations.

Driver for the CIMaX SP2 common interface chip. It is very much based on the existing cimax2 driver for cx23885, but should be more reusable. The product has been sold with name Atmel T90FJR as well and the data sheets for that chip seem to be publicly available. It seems that the USB device that I have and the cx23885 based devices will need to interact differently with the chip for the CAM operations. Thus there is one callback function that is passed on to the sp2 driver (see function sp2_ci_op_cam for that one). IRQ functionality is not included currently (not needed by USB devices and I don't have a PCIe device for development). Signed-off-by:

Olli Salonen authored
Luis Alves submitted a TS mode patch to si2168 earlier, but the patch was rejected due to a small issue. Here is a working version. Also, setting of TS mode is moved from si2168_set_frontend to si2168_init. This patch adds the TS mode as a config option for the si2168 demod: - ts_mode added to config struct. - Possible (interesting) values are * Parallel mode = 0x06 * Serial mode = 0x03 Currently the modules using this demod only use parallel mode.

Normally, ADAP_STREAMING bit is set in dvb_usb_start_feed and cleared in dvb_usb_stop_feed. But in exceptional cases, for example, when the tv is playing programs and the tuner is pulled out, then dvb_usbv2_disconnect is called. In such case, it will first call dvb_usbv2_adapter_frontend_exit to stop dvb_frontend_thread, and then call dvb_usbv2_adapter_dvb_exit to clear ADAP_STREAMING bit. At this point, if dvb_frontend_thread is sleeping and waiting for ADAP_STREAMING to be cleared to get out of sleep. then dvb_frontend_thread can never be stoped, because clearing ADAP_STREAMING bit is performed after dvb_frontend_thread is stopped (i.e. performed in dvb_usbv2_adapter_dvb_exit).

There are several arch-specific media drivers that don't require asm-specific includes and can be successfully compiled on x86.
