Subject: [PATCH v12 22/86] media: Documentation: Add subdev configuration models, raw sensor model
Date: Thu, 9 Apr 2026 23:13:57 +0300 [thread overview]
Message-ID: <20260409201501.975242-23-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20260409201501.975242-1-sakari.ailus@linux.intel.com>
Sub-device configuration models define what V4L2 API elements are
available on a compliant sub-device and how do they behave.
The patch also adds a model for common raw sensors.

+
+Sub-device configuration models
+===============================
+
+The V4L2 specification defines a subdev API that exposes three type of
+configuration elements: formats, selection rectangles and controls. The
+specification contains generic information about how those configuration
+elements behave, but not precisely how they apply to particular hardware
+features. We leave some leeway to drivers to decide how to map selection
+rectangles to device features, as long as they comply with the V4L2
+specification. This is needed as hardware features differ between devices, so
+it's the driver's responsibility to handle this mapping.
+
+Unfortunately, this lack of clearly defined mapping in the specification has led
+to different drivers mapping the same hardware features to different API
+elements, or implementing the API elements with slightly different
+behaviours. Furthermore, many drivers have implemented selection rectangles in
+ways that do not comply with the V4L2 specification. All of this makes userspace
+development difficult.
+
+Sub-device configuration models specify in detail what the user space can expect
+from a sub-device in terms of V4L2 sub-device interface support, semantics
+included.
+
+A sub-device may implement more than one configuration model at the same
+time. The implemented configuration models can be obtained from the sub-device's
+``V4L2_CID_CONFIG_MODEL`` control.
+
+.. _media_subdev_config_model_common_raw_sensor:
+
+Common raw camera sensor model
+------------------------------
+
+The common raw camera sensor model defines a set of enumeration and
+configuration interfaces (formats, selections etc.) that cover the vast majority
+of functionality of raw camera sensors. Not all of the interfaces are
+necessarily offered by all drivers.
+
+A sub-device complies with the common raw sensor model if the
+``V4L2_CONFIG_MODEL_COMMON_RAW_SENSOR`` bit is set in the
+``V4L2_CID_CONFIG_MODEL`` control of the sub-device.
+
+The common raw camera sensor model is aligned with
+:ref:`media_using_camera_sensor_drivers`. Please refer to that regarding aspects
+not specified here.
+
+Each camera sensor implementing the common raw sensor model exposes a single
+V4L2 sub-device. The sub-device contains a single source pad (0) and two or more
+internal pads: one or more image data internal pads (starting from 1) and
+optionally an embedded data pad.
+
+Additionally, further internal pads may be supported for other features. Using
+more than one image data internal pad or more than one non-image data pad
+requires these pads documented separately for the given device. The indices of
+the image data internal pads shall be lower than those of the non-image data
+pads.
+
+This is shown in :ref:`media_subdev_config_model_common_raw_sensor_subdev`.

+
+Sensor pixel array size, cropping and binning
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The sensor's pixel array is divided into one or more areas. The areas around the
+the visible pixel area in the pixel array, usually one or more sides, may
+contain optical black pixels, dummy pixels and other non-image pixels. The full
+size of the pixel array, including pixels that cannot be captured, is conveyed
+by the format on (pad, stream) pair 1/0.
+
+Capturing the non-visible pixels outside the visible pixel area may be supported
+by the sensor. This area corresponds to the ``V4L2_SEL_TGT_CROP_BOUNDS``
+selection target on (pad, stream) pair 1/0. Non-visible pixels may include
+optical black pixels, dummy pixels or other non-visible pixels. The visible
+pixel area corresponds to the ``V4L2_SEL_TGT_CROP_DEFAULT`` selection target on
+(pad, stream) pair 1/0.
+
+A rectangle within the pixel array contains the visible pixels. Capturing the
+non-visible pixels outside the visible pixel area may be supported by the
+sensor. The visible pixel area corresponds to the ``V4L2_SEL_TGT_CROP_DEFAULT``
+selection target on (pad, stream) pair 1/0.
+
+Sensors can perform multiple operations that affect the output image size. The first
+of these is the analogue crop. Analogue crop limits the area of the pixel array
+which the sensor will read, affecting sensor timing as well. The granularity of
+the analogue crop configuration varies greatly across sensors: some sensors
+support only a few different analogue crop configurations whereas others may
+support anything divisible by a given number of pixels. The analogue crop
+configuration corresponds to the ``V4L2_SEL_TGT_CROP`` selection target on (pad,
+stream) pair 1/0. The default analogue crop rectangle corresponds to the visible
+pixel area.
+
+In the next step, binning is performed on the image data read from camera
+sensor's pixel array, as determined by the analogue crop configuration. Enabling
+binning will effectively result in an image smaller than the original by given
+binning factors horizontally and vertically. Typical values are 1/2 and 1/3 but
+others may well be supported by the hardware as well.
+
+Sub-sampling follows binning. Sub-sampling, like binning, reduces the size of
+the image by including only a subset of samples read from the sensor's pixel
+matrix, typically every n'th pixel horizontally and vertically, taking the
+sensor's color pattern into account. Sub-sampling is generally configurable
+separately horizontally and vertically.
+
+The combined effect of binning and sub-sampling is configured using the
+``V4L2_SEL_TGT_COMPOSE`` rectangle, relative to the analogue crop rectangle, on
+(pad, stream) pair 1/0. The driver implementation determines how to configure
+binning and sub-sampling to achieve the desired size.
+
+The digital crop operation takes place after binning and sub-sampling. It is
+configured by setting the ``V4L2_SEL_TGT_CROP`` rectangle on (pad, stream) pair
+0/0. The resulting image size is further output by the sensor on the sensor's
+data interface.
+
+The sensor's output mbus code is configured by setting the format on the (pad,
+stream) pair 0/0. When setting the format, always use the same width and height
+as for the digital crop setting.
+
+Drivers may only support some or even none of these configurations, in which
+case they do not expose the corresponding selection rectangles. If any selection
+targets are omitted, the further selection rectangle or format is instead
+related to the previous implemented selection rectangle. For instance, if the
+sensor supports binning but not analogue crop, then the binning configuration
+(``V4L2_SEL_TGT_COMPOSE`` selection target) is done in relation to the visible
+pixel area (``V4L2_SEL_TGT_CROP_DEFAULT`` selection target).
+
+Also refer to :ref:`Selection targets <v4l2-selection-targets-table>`.

+
+Embedded data
+^^^^^^^^^^^^^
+
+The embedded data stream is produced by the sensor when the corresponding route
+is enabled. The embedded data route may also be immutable or not exist at all,
+in case the sensor (or the driver) does not support it.
+
+Generally the sensor embedded data width is determined by the width of the image
+data whereas the number of lines are constant for the embedded data. The user
+space may obtain the size of the embedded data once the image data size on the
+source pad has been configured.
+
+Also see :ref:`media_using_camera_sensor_drivers_embedded_data`.
