* | [media] v4l2_plane_pix_format: use __u32 bytesperline instead of __u16Hans Verkuil2015-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running v4l2-compliance tests on vivid I suddenly got errors due to a call to vmalloc_user with size 0 from vb2. Digging deeper into the cause I discovered that this was due to the fact that struct v4l2_plane_pix_format defines bytesperline as a __u16 instead of a __u32. The test I was running selected a format of 4 * 4096 by 4 * 2048 with a 32 bit pixelformat. So bytesperline was 4 * 4 * 4096 = 65536, which becomes 0 in a __u16. And bytesperline * height is suddenly 0 as well. While the vivid driver may be a virtual driver, it is to be expected that this limit will be hit for real hardware as well in the near future: 8k deep-color video will already reach it. The solution is to change the type to __u32. The only drivers besides vivid that use the multiplanar API are little-endian ARM and SH platforms (exynos, ti-vpe, vsp1), so this is safe.

* | [media] DocBook v4l: update bytesperline handlingHans Verkuil2015-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation says that the bytesperline field in v4l2_pix_format refers to the largest plane in the case of planar formats (i.e. multiple planes stores in a single buffer). For almost all planar formats the first plane is also the largest (or equal) plane, except for two formats: V4L2_PIX_FMT_NV24/NV42. For this YUV 4:4:4 format the second chroma plane is twice the size of the first luma plane. Looking at the very few drivers that support this format the bytesperline value that they report is actually that of the first plane and not that of the largest plane. Rather than fixing the drivers it makes more sense to update the documentation since it is very difficult to use the largest plane for this. You would have to check what the format is in order to know to which plane bytesperline belongs, which makes calculations much more difficult. This patch updates the documentation accordingly.

* | [media] media.h: mark alsa struct in media_entity_desc as TODOHans Verkuil2015-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alsa struct in struct media_entity_desc is now marked as deprecated. However, the alsa struct should remain as it is since it cannot be replaced by a simple major/minor device node description. The alsa struct was designed to be used as an alsa card description so V4L2 drivers could use this to expose the alsa card that they create to carry the captured audio. Such a card is not just a PCM device, but also needs to contain the alsa subdevice information, and it may map to multiple devices, e.g. a PCM and a mixer device, such as the au0828 usb stick creates. This is exactly as intended and this cannot and should not be replaced by a simple major/minor. However, whether this information is in the right form for an ALSA device such that it can handle udev renaming rules as well is another matter. So mark this alsa struct as TODO and document the problems involved. Updated the documentation as well to reflect this and to add the 'major' and 'minor' field documentation. Updated the documentation to clearly state that struct dev is to be used for (sub-)devices that create a single device node. Other devices need their own structure here.

| | | | | | | | | | | | | | In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed them with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Update the v4l documentation accordingly.

It contains some typo fixes, a few minor documentation improvements, and, most importantly, fixes for a couple of build problems in various bits of sample code. I fully intend to start sending pull requests with signed tags. However, due to poor planning on my part and the general obnoxiousness of life, I'm 2000 miles away from my private key which is sitting on a powered-down machine. This should be fixed before my next request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Documentation for enum v4l2_field did not make it clear that V4L2_FIELD_ANY is only acceptable as input to the kernel, not as a response from the driver. Make it clear, to stop userspace developers like me assuming it can be returned by the driver.
