Add the ivtv-fb framebuffer driver for cx23415 devices (currently only the Hauppauge PVR-350 cards). This makes it possible to use the On-Screen Display functionality of these cards, either for menus during MPEG playback, or as a console or X display.

Add permissions to all the module parameters so they can be queried and set (when possible) via sysfs. Add description for the vidmem parameter. Change the video_nr parameter to an array, so that the video number can be specified when a user has more than one card. The driver would try to give all cards the same number otherwise, which will fail for all cards after the first. The default_input option would only allow values of 0 or 1, contrary to the description. Allow values up to the number of inputs defined for the card. Add description of lock_norm's different behavior for 1 and >1. Signed-off-by: NTrent Piepho <xyzzy@speakeasy.org> Acked-by: NRonald S.

Debugging cleanups to the zr36067 driver: * Use module_param_named() to declare the debug parameter, so we can use a single global variable to handle the debug level. This makes the driver a bit smaller (by 648 bytes on x86_64), thanks to one less level of indirection on every use. * Change the debug parameter sysfs permissions, so that the debug level can be adjusted at runtime, as is done in many other media/video drivers. * The debug level is between 0 and 5, not 0 and 4. * Move the zr_debug export and dprintk macro definition to a header file so that we don't have to define them in each source file. * Simplify a duplicate test on zr_debug. Note that zr_debug was subsequently renamed to debug_zr36067 to avoid possible conflicts with other Zoran device drivers, on a suggestion by Trent Piepho.

This patch adds an internal ioctl-like interface which can be used in situations where a single Video4Linux device is implemented by multiple device drivers. One master device controls one or more slave devices. The slaves provide Video4Linux ioctl-like interface for the use of the master. Only a handful of ioctls are implemented at the moment.

Right now the composite sound input doesn't work on AverTV 307 because of the wrong mux setup. The composite sound is routed via an external 4channel multiplexer controlled by GPIO, while the code assumes an internal multiplexer instead.

Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong frame types were filled in: the B and P frame types were swapped. This bug also hid a second bug: when a capture is stopped a last entry is written into the pgm index buffer with internal type 0, denoting the end of the program. This entry wasn't ignored, instead it was accidentally returned to the caller as a P frame.

Git changeset 6bdcc6e6 dropped the stand-alone lgh06xf module, whose functionality was absorbed into the dvb-pll module. However, there was a minor difference between the code in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop devices using the LG-H06xF NIM. dvb-pll will probe for the presence of an i2c pll chip by performing a single byte read, the lgh06xf driver did not do this. Unfortunately, the code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads as a probe. Such probes with the current code will always fail. In order to work around this problem, and restore proper functionality of the Airstar HD5000 device, this hack was created to make the probe appear to succeed. The single byte read in dvb_pll_attach is the only place where such a probe would ever occur, so this change is safe, and will not affect any other devices. Of course, if one knew how to actually perform the read operation, it would be better to go that route. In the meantime, however, we must apply this workaround, in order to prevent the regression that causes tuning to fail on the Airstar HD5000 ATSC device. Thanks to Jarod Wilson, who had originally reported this regression, and to Geoffrey Hausheer, whose original workaround patch led us to find the actual cause of the problem.

Configuring the OLPC camera requires something over 150 register writes. Unfortunately, querying the CAFE i2c controller too soon after a write causes the hardware to flake. The problem had been "solved" with an msleep() call, but, between the number of registers and how msleep() behaves, that resulted in a 3-second delay on camera initialization. Instead, we hand-code a wait for the completion interrupt which avoids reading the status registers.

Various gpio and mux settings for the Osprey 440 weren't correct. Fix them and provide some documentation about how the gpios work. The osprey eeprom routine wasn't run for the 440, add it. It was also crap, re-written to be better. Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample rate is fixed at 32kHz, as the driver doesn't support different rates for digital input mode, though the card can select the rate from 32, 44.1, or 48 kHz via gpio. Setting the audio gain via ALSA isn't supported yet; a userspace tool that programs the X9221 via i2c-dev must be used. The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC used, resulting in extremely garbled sound. That is fixed in a followup patch.

When raw capture was turned off, the current capturing frame (v4l_grab_frame) wasn't reset to NO_GRAB_ACTIVE. If capture was turned back on, the driver would think this frame was currently being captured, and wait for it to complete before starting a new frame. The hardware on the other hand would not be actively capturing a frame. The result was the driver would wait forever for v4l_grab_frame to be captured. Some calls to zr36057_set_memgrab(0) were missing spin-locks, which have been added. Signed-off-by: NTrent Piepho <xyzzy@speakeasy.org> Acked-by: NRonald S.

Add support for the UYVY and the other big endian output formats. The driver was naming formats based on the host endianess. This is different that all the other drivers appear to work and not what software appears to expect. Use ARRAY_SIZE() to find the the size of the zoran_formats array. Change the way the driver handles setting the video format register. Rather than use some if and switch statements to set to register by looking at the format id, the format list simply has a field with the proper bits to set. Adds a bit of ifdef to make a driver without V4L1 support more possible. Also create a macro for defining formats that handles vl41 and/or vl42 support to avoid repeated ifdefs in the format list.

The driver was returning the size of the (fixed) buffer it allocated as the sizeimage field in the v4l2 pixel format, rather than the actual size of the image. For example, a 192x128 YUYV image is 49152 bytes but the driver would always return 131072 bytes since if that was the size of the v4l buffer. This violates the v4l2 spec, which says that sizeimage should be the actual size of the image for uncompressed formats. It also caused mplayer to crash.

During uncompressed capture, the poll() function was looking the wrong frame. It was using the frame the driver was going to capture into next (pend_tail), when it should have been looking at the next frame to be de-queued with DQBUF/SYNC (sync_tail). It also wasn't looking in the right spot. It was looking at the file handle's copy of the buffer status, rather than the driver core copy. The interrupt routine marks frames as done in the driver core copy, the file handle copy isn't updated. So even if poll() looked at the right frame, it would never see it transition to done and return POLLIN. The compressed capture code has this same problem, looking in fh->jpg_buffers when it should have used zr->jpg_buffers. There was some logic to detect when there was no current capture in process nor any frames queued and try to return an error, which ends up being a bad idea. It's possible to call select() from one thread while no capture is in process, or no frames queued, and then start a capture or queue frames from another thread. The buffer state variables are protected by a spin lock, which the code wasn't acquiring. That is fixed too. Signed-off-by: NTrent Piepho <xyzzy@speakeasy.org> Acked-by: NRonald S.

The zr36067 driver doesn't make a distinction between the different sub-types of NTSC, PAL, or SECAM norms. For example, when the enum std ioctl returns the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I. When setting the norm, it required the bitmask to match exactly the set of norms used during the enumeration. If just one norm was specified, for example PAL_BG or NTSC_M, it would fail. This violates the V4L2 spec, "VIDIOC_S_STD accepts *one* or more flags..." The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple bits. It's ok to call S_STD with any *one* of those bits, but the driver was requiring *all* of them. This fixes the S_STD function so that it will accept any set of one or more PAL norms as PAL, and the same for NTSC and SECAM. Signed-off-by: NTrent Piepho <xyzzy@speakeasy.org> Acked-by: NRonald S.
