This adds detailed documentation about the driver's extension unit control features. Part of it has been adopted from the dynctrl.txt that used to be available in the driver's previous Subversion repository. The documentation has been rewritten to match the current implementation, in particular to capture the new XU control support including UVCIOC_CTRL_QUERY. Signed-off-by:

This ioctl extends UVCIOC_CTRL_GET/SET by not only allowing to get/set XU controls but to also send arbitrary UVC commands to XU controls, namely GET_CUR, SET_CUR, GET_MIN, GET_MAX, GET_RES, GET_LEN, GET_INFO and GET_DEF. This is required for applications to work with XU controls, so that they can properly query the size and allocate the necessary buffers. Signed-off-by:

To simplify maintainer support of this driver, bump the version to 1.5.0 - this will be the first version that is expected to support mmap() for raw video frames. Signed-off-by:

The initial version of this patch (commit d5976931639176bb6777755d96b9f8d959f79e9e) had some issues: * It didn't correctly calculate the size of the YUV buffer for 4:2:2, resulting in capture sometimes being offset by 1/3rd of a picture. * There were a lot of variables duplicating information the driver already knew, which have been removed. * There was an in-kernel format conversion - libv4l can do this one, and is the right place to do format conversions anyway. * Some magic numbers weren't properly explained. Fix all these issues, leaving just the move from videobuf to videobuf2 to do. Signed-off-by:

Remove old DVB-T2 freq module param and detect DVB-T/T2 automatically. Implementation is trial and error, if DVB-T does not lock try DVB-T2 and vice versa. That's done by replacing normal DVBFE_ALGO_SW with DVBFE_ALGO_CUSTOM which gives better control for tuning process. DVB-C still uses normal software ZigZag, DVBFE_ALGO_SW. Signed-off-by:

Change firmware download split, which I introduced few patch earlier, a little bit to make it more readable as requested [1]. Anyhow, for some reason this seems to increase compiled binary size 52 bytes, on my AMD64 box, which is rather much for so small change.

Currently video capturing using streaming I/O method doesn't work if capturing to overlay buffer took place before. When enabling the stream we have to check the overlay enable driver flag and reset it so that the interrupt handler won't execute the overlay interrupt path after enabling DMA in streamon routine. Otherwise the capture interrupt won't be handled correctly causing non working VIDIOC_DQBUF ioctl. Signed-off-by:

Currently the driver enables overlay when running VIDIOC_S_FMT ioctl with fmt type V4L2_BUF_TYPE_VIDEO_OVERLAY. Actually, this is wrong. Add proper VIDIOC_OVERLAY support instead of using VIDIOC_S_FMT for overlay enable. Signed-off-by:

usb_altnum_to_altsetting() may return NULL. If it does we'll dereference a NULL pointer in drivers/media/video/gspca/stv06xx/stv06xx_pb0100.c::pb0100_start(). As far as I can tell there's not really anything more sensible than -ENODEV that we can return in that situation, but I'm not at all intimate with this code so I'd like a bit of review/comments on this before it's applied. Anyway, here's a proposed patch. Signed-off-by:

If an IR command is sent (using the LIRC userspace) to rc-loopback which doesn't include a trailing space, the result is that the message won't be completely decoded. In addition, "leftovers" from a previous transmission can be left until the next one. Fix this by faking a long silence after the end of TX data. Signed-off-by:

Jonathan Nieder authored
It should not be possible to enter mpeg_open and acquire core->lock without the blackbird driver being registered, so just error out if it is not. This makes the code more readable and should prevent the bug fixed by the patch "hold device lock during sub-driver initialization" from resurfacing again. Similarly, if we enter mpeg_release and acquire core->lock then either the blackbird driver is registered (since open files keep it loaded) or the sysadmin forced the driver's removal. In the latter case the state will be inconsistent and this is worth a loud warning. Tested-by:

Add and use a mutex to protect the cx88-mpeg device list. Previously the BKL prevented races. Based on work by Ben Hutchings <ben@decadent.org.uk>. Tested-by:

Jonathan Nieder authored
cx8802_blackbird_probe makes a device node for the mpeg sub-device before it has been added to dev->drvlist. If the device is opened during that time, the open succeeds but request_acquire cannot be called, so the reference count remains zero. Later, when the device is closed, the reference count becomes negative --- uh oh. Close the race by holding core->lock during probe and not releasing until the device is in drvlist and initialization finished. Previously the BKL prevented this race. Reported-by:
