media: uapi: videodev2: Add V4L2_META_FMT_RK_ISP1_EXT_PARAMS

2024-08-12T10:36:32+00:00

The rkisp1 driver stores ISP configuration parameters in the fixed rkisp1_params_cfg structure. As the members of the structure are part of the userspace API, the structure layout is immutable and cannot be extended further. Introducing new parameters or modifying the existing ones would change the buffer layout and cause breakages in existing applications. The allow for future extensions to the ISP parameters, introduce a new extensible parameters format, with a new format 4CC. Document usage of the new format in the rkisp1 admin guide.

media: uapi: v4l: Don't expose generic metadata formats to userspace

2024-04-29T12:56:38+00:00

The generic metadata pixel formats (V4L2_META_FMT_GENERIC_*) are meant to be used in conjunction with device-specific media bus codes. Those codes are work in progress and not available in the upstream kernel yet. To make sure the generic metadata pixel formats won't be used by userspace until we have the full infrastructure in place, keep their definition private to the kernel for now.

media: v4l: Add V4L2-PIX-FMT-Y14P format

2024-04-29T12:56:37+00:00

This is a packed grey-scale image format with a depth of 14 bits per pixel. Every four consecutive samples are packed into seven bytes. Each of the first four bytes contain the eight high order bits of the pixels, and the three following bytes contains the six least significants bits of each pixel, in the same order. As the other formats only needed 5 bytes before, append two bytes in the documentation array.

This is a packed grey-scale image format with a depth of 12 bits per pixel. Two consecutive pixels are packed into 3 bytes. The first 2 bytes contain the 8 high order bits of the pixels, and the 3rd byte contains the 4 least significants bits of each pixel, in the same order.

media: v4l: Support line-based metadata capture

2024-04-29T12:56:36+00:00

Many camera sensors, among other devices, transmit embedded data and image data for each CSI-2 frame. This embedded data typically contains register configuration of the sensor that has been used to capture the image data of the same frame. The embedded data is received by the CSI-2 receiver and has the same properties as the image data, including that it is line based: it has width, height and bytesperline (stride). Add these fields to struct v4l2_meta_format and document them. Also add V4L2_FMT_FLAG_META_LINE_BASED to tell a given format is line-based i.e. these fields of struct v4l2_meta_format are valid for it.
