Use the expression "video stream" instead of "color camera" which is more correct as the driver supports the RGB and IR image on the same endpoint. Signed-off-by:

Move large communications buffers out of stack and into device structure. This prevents the frame size from being >1kB and fixes a compiler warning when CONFIG_FRAME_WARN=1024: drivers/media/video/gspca/kinect.c: In function ‘send_cmd.clone.0’: drivers/media/video/gspca/kinect.c:202: warning: the frame size of 1548 bytes is larger than 1024 bytes Reported-by:

This patch removes the remaining on-stack buffer for USB DMA transfer. This patch also reduces the stack memory usage. Cc: stable@kernel.org Cc: Florian Mickler <florian@mickler.org> Signed-off-by:

I misused the ktime API, and failed to remove some traces of the in-kernel format conversion. Fix these, so the the driver builds without warnings. Signed-off-by:

Move the public API definitions to include/linux/uvcvideo.h and bump the version number to 1.1.0. Compatibility with the old API is kept, application can still be compiled against the private header and will not break. Signed-off-by:

Instead of passing the value down to the device and getting an error back (or worse, crashing the firmware), return -ERANGE when the requested menu entry is not supported. Signed-off-by:

Supported menu entries are reported by the device in response to the GET_RES query. Use the information to return -EINVAL to userspace for unsupported values when enumerating menu entries. Signed-off-by:

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:

Those ioctls are deprecated, list them in the features removal schedule for 2.6.42. Signed-off-by:
-
Martin Rubli authored
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:

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:
