* [media] vivid: return -ENODATA if the current input doesn't support ↵Hans Verkuil2016-08-24
| | | | | | | | | | | | | | | | | | | | g/s_selection Returning -EINVAL indicates wrong arguments, but that's not the case here. Returning -ENOTTY is also no option, since the ioctl is implemented, but it just is not valid for this input. So use -ENODATA instead. This is also used elsewhere when an ioctl isn't valid for a specific input. In this case G/S_SELECTION returned -EINVAL for the webcam input. That input doesn't support cropping, instead it uses ENUM_FRAMESIZES to enumerate a list of discrete frame sizes.

* [media] vivid: fix broken Bayer text renderingHans Verkuil2016-02-01
| | | | | | | | | | | | | | | | | | | | | | Sometimes when a Bayer pixelformat is selected the rendering of the OSD text by vivid was all wrong: every other line of the text was shifted by half the width or more. It turned out that to render Bayer formats the interleaved boolean is set to true in the tpg. This mode indicates a semi-biplanar mode where two interleaved planes are used to render the frame. From outside the tpg it looks like a single plane, but internally it is two planes. However, in the tpg_s_bytesperline() function the interleaved bool wasn't checked and only the bytesperline value for plane 0 was updated. But for the interleaved mode the same value has to be copied to bytesperline[1] as well. The effect was that whatever old value was left in bytesperline[1] was used, which caused all sorts of weird and seemingly unpredictable shifts.

* [media] vb2: drop v4l2_format argument from queue_setupHans Verkuil2015-12-18
| | | | | | | | | | | | | | | | | | | | | The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] v4l2-dv-timings: add support for reduced blanking v2Prashant Laddha2015-07-06
| | | | | | | | | | | | | | | | | | | | Added support for reduced blanking version 2 (RB v2) in cvt timings. Standard specifies a fixed vsync pulse of 8 lines to indicate RB v2 timings. Vertical back porch is fixed at 6 lines and vertical front porch is remainder of vertical blanking time. For RB v2, horizontal blanking is fixed at 80 pixels. Horizontal sync is fixed at 32. All horizontal timing counts (active pixels, front, back porches) can be specified upto a precision of 1. RB v2 allows for non standard aspect ratios. In RB v2 vsync does not indicate aspect ratio. In absence of aspect ratio v4l2_detect_cvt() cannot calculate image width from image height. Hence extending the v4l2_detect_cvt() to pass image width in case of RB v2.

Populated vsync, vertical front, back porch values in bt timing structure for even and odd fields and updated the flags appropriately. Also modified the functions calling the detect_cvt/gtf(). As of now these functions are calling detect_cvt/gtf() with interlaced flag set to false.

* [media] vivid-tpg: improve Y16 color setupHans Verkuil2015-06-06
| | | | | | | | | | | | Currently the colors for the Y16 and Y16_BE pixelformats are in the range 0x0000-0xff00. So pure white (0xffff) is never created. Improve this by making white really white. For other colors the lsb remains 0 so vivid can be used to detect endian problems.

* [media] vivid: move video loopback control to the capture deviceHans Verkuil2015-06-06
| | | | | | | | | | | | | This has been on my TODO list for some time now: the control that enables the video loopback was part of the controls of the video output device instead of the video capture device. In practice this was quite annoying since you expect it at the capture side since that's where you want to make the decision whether to use the TPG or looped video. This patch moves the control from the output to the capture side. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: move PRINTSTR to separate functionsHans Verkuil2015-06-05
| | | | | | | | | | | | | | | | | | | Commit 84cb7be43cec12868e94163c99fdc34c0297c3b8 broke vivid-tpg (uninitialized variable p). This patch takes a different approach: four different functions are created, one for each PRINTSTR version. In order to avoid the 'the frame size of 1308 bytes is larger than 1024 bytes' warning I had to mark those functions with 'noinline'. For whatever reason gcc seems to inline this aggressively and it is doing weird things with the stack. I tried to read the assembly code, but I couldn't see what exactly it was doing on the stack.
