2024-08-12media: uapi: videodev2: Add V4L2_META_FMT_RK_ISP1_EXT_PARAMSJacopo Mondi1-0/+1
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.

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.

2024-04-29media: v4l: Support line-based metadata captureSakari Ailus1-0/+10
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.

2024-04-29media: uapi: v4l: Add generic 8-bit metadata format definitionsSakari Ailus1-0/+8
Generic 8-bit metadata formats define the in-memory data layout but not the format of the data itself. The reasoning for having such formats is to allow CSI-2 receiver drivers to receive and DMA drivers to write the data to memory without knowing a large number of device-specific formats. These formats may be used only in conjunction with a Media Controller pipeline where the internal pad of the source sub-device defines the specific format of the data (using an mbus code).

The structure is packed, which requires that all its fields need to be also packed. ./include/uapi/linux/videodev2.h:1810:2: warning: field within 'struct v4l2_ext_control' is less aligned than 'union v4l2_ext_control::(anonymous at ./include/uapi/linux/videodev2.h:1810:2)' and is usually due to 'struct v4l2_ext_control' being packed, which can lead to unaligned accesses [-Wunaligned-access] Explicitly set the inner union as packed.

When the ``type`` is set to ``V4L2_INPUT_TYPE_TUNER`` this is an RF connector and this field identifies the tuner. It corresponds to struct :c:type:`v4l2_tuner` field ``index``. For details on tuners see :ref:`tuner`. " Drivers I could find also use the 'tuner' field as an index, e.g.: drivers/media/pci/bt8xx/bttv-driver.c bttv_enum_input() drivers/media/usb/go7007/go7007-v4l2.c vidioc_enum_input() However, the UAPI comment claims this field is 'enum v4l2_tuner_type': include/uapi/linux/videodev2.h This field being 'enum v4l2_tuner_type' is unlikely as it seems to be never used that way in drivers, and documentation confirms it.

Add a new flag that indicates that this control is a dynamically sized array. Also document this flag. Currently dynamically sized arrays are limited to one dimensional arrays, but that might change in the future if there is a need for it. The initial use-case of dynamic arrays are stateless codecs. A frame can be divided in many slices, so you want to provide an array containing slice information for each slice. Typically the number of slices is small, but the standard allow for hundreds or thousands of slices. Dynamic arrays are a good solution since sizing the array for the worst case would waste substantial amounts of memory.
