* Sony IMX290 1/2.8-Inch CMOS Image Sensor
|
||||
|
||||
The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with
|
||||
Square Pixel for Color Cameras. It is programmable through I2C and 4-wire
|
||||
interfaces. The sensor output is available via CMOS logic parallel SDR output,
|
||||
Low voltage LVDS DDR output and CSI-2 serial data output. The CSI-2 bus is the
|
||||
default. No bindings have been defined for the other busses.
|
||||
|
||||
Required Properties:
|
||||
- compatible: Should be "sony,imx290"
|
||||
- reg: I2C bus address of the device
|
||||
- clocks: Reference to the xclk clock.
|
||||
- clock-names: Should be "xclk".
|
||||
- clock-frequency: Frequency of the xclk clock in Hz.
|
||||
- vdddo-supply: Sensor digital IO regulator.
|
||||
- vdda-supply: Sensor analog regulator.
|
||||
- vddd-supply: Sensor digital core regulator.
|
||||
|
||||
Optional Properties:
|
||||
- reset-gpios: Sensor reset GPIO
|
||||
|
||||
The imx290 device node should contain one 'port' child node with
|
||||
an 'endpoint' subnode. For further reading on port node refer to
|
||||
Documentation/devicetree/bindings/media/video-interfaces.txt.

**************************************************
|

Memory-to-memory Stateless Video Decoder Interface
|
||||
**************************************************
|
||||
|
||||
A stateless decoder is a decoder that works without retaining any kind of state
|
||||
between processed frames. This means that each frame is decoded independently
|
||||
of any previous and future frames, and that the client is responsible for
|
||||
maintaining the decoding state and providing it to the decoder with each
|
||||
decoding request. This is in contrast to the stateful video decoder interface,
|
||||
where the hardware and driver maintain the decoding state and all the client
|
||||
has to do is to provide the raw encoded stream and dequeue decoded frames in
|
||||
display order.
|
||||
|
||||
This section describes how user-space ("the client") is expected to communicate
|
||||
with stateless decoders in order to successfully decode an encoded stream.
|
||||
Compared to stateful codecs, the decoder/client sequence is simpler, but the
|
||||
cost of this simplicity is extra complexity in the client which is responsible
|
||||
for maintaining a consistent decoding state.
|
||||
|
||||
Stateless decoders make use of the :ref:`media-request-api`. A stateless
|
||||
decoder must expose the ``V4L2_BUF_CAP_SUPPORTS_REQUESTS`` capability on its
|
||||
``OUTPUT`` queue when :c:func:`VIDIOC_REQBUFS` or :c:func:`VIDIOC_CREATE_BUFS`
|
||||
are invoked.
|
||||
|
||||
Depending on the encoded formats supported by the decoder, a single decoded
|
||||
frame may be the result of several decode requests (for instance, H.264 streams
|
||||
with multiple slices per frame). Decoders that support such formats must also
|
||||
expose the ``V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF`` capability on their
|
||||
``OUTPUT`` queue.
|
||||
|
||||
Querying capabilities
|
||||
=====================
|
||||
|
||||
1. To enumerate the set of coded formats supported by the decoder, the client
|
||||
calls :c:func:`VIDIOC_ENUM_FMT` on the ``OUTPUT`` queue.
|
||||
|
||||
* The driver must always return the full set of supported ``OUTPUT`` formats,
|
||||
irrespective of the format currently set on the ``CAPTURE`` queue.
|
||||
|
||||
* Simultaneously, the driver must restrain the set of values returned by
|
||||
codec-specific capability controls (such as H.264 profiles) to the set
|
||||
actually supported by the hardware.
|
||||
|
||||
2. To enumerate the set of supported raw formats, the client calls
|
||||
:c:func:`VIDIOC_ENUM_FMT` on the ``CAPTURE`` queue.
|
||||
|
||||
* The driver must return only the formats supported for the format currently
|
||||
active on the ``OUTPUT`` queue.
|
||||
|
||||
* Depending on the currently set ``OUTPUT`` format, the set of supported raw
|
||||
formats may depend on the value of some codec-dependent controls.
|
||||
The client is responsible for making sure that these controls are set
|
||||
before querying the ``CAPTURE`` queue. Failure to do so will result in the
|
||||
default values for these controls being used, and a returned set of formats
|
||||
that may not be usable for the media the client is trying to decode.
|
||||
|
||||
3. The client may use :c:func:`VIDIOC_ENUM_FRAMESIZES` to detect supported
|
||||
resolutions for a given format, passing desired pixel format in
|
||||
:c:type:`v4l2_frmsizeenum`'s ``pixel_format``.
|
||||
|
||||
4. Supported profiles and levels for the current ``OUTPUT`` format, if
|
||||
applicable, may be queried using their respective controls via
|
||||
:c:func:`VIDIOC_QUERYCTRL`.
|
||||
|
||||
Initialization
|
||||
==============
|
||||
|
||||
1. Set the coded format on the ``OUTPUT`` queue via :c:func:`VIDIOC_S_FMT`.
|
||||
|
||||
* **Required fields:**
|
||||
|
||||
``type``
|
||||
a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``.
|
||||
|
||||
``pixelformat``
|
||||
a coded pixel format.
|
||||
|
||||
``width``, ``height``
|
||||
coded width and height parsed from the stream.
|
||||
|
||||
other fields
|
||||
follow standard semantics.
|
||||
|
||||
.. note::
|
||||
|
||||
Changing the ``OUTPUT`` format may change the currently set ``CAPTURE``
|
||||
format. The driver will derive a new ``CAPTURE`` format from the
|
||||
``OUTPUT`` format being set, including resolution, colorimetry
|
||||
parameters, etc. If the client needs a specific ``CAPTURE`` format,
|
||||
it must adjust it afterwards.
|
||||
|
||||
2. Call :c:func:`VIDIOC_S_EXT_CTRLS` to set all the controls (parsed headers,
|
||||
etc.) required by the ``OUTPUT`` format to enumerate the ``CAPTURE`` formats.
|
||||
|
||||
3. Call :c:func:`VIDIOC_G_FMT` for ``CAPTURE`` queue to get the format for the
|
||||
destination buffers parsed/decoded from the bytestream.
|
||||
|
||||
* **Required fields:**
|
||||
|
||||
``type``
|
||||
a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``.
|
||||
|
||||
* **Returned fields:**
|
||||
|
||||
``width``, ``height``
|
||||
frame buffer resolution for the decoded frames.
|
||||
|
||||
``pixelformat``
|
||||
pixel format for decoded frames.
|
||||
|
||||
``num_planes`` (for _MPLANE ``type`` only)
|
||||
number of planes for pixelformat.
|
||||
|
||||
``sizeimage``, ``bytesperline``
|
||||
as per standard semantics; matching frame buffer format.
|
||||
|
||||
.. note::
|
||||
|
||||
The value of ``pixelformat`` may be any pixel format supported for the
|
||||
``OUTPUT`` format, based on the hardware capabilities. It is suggested
|
||||
that the driver chooses the preferred/optimal format for the current
|
||||
configuration. For example, a YUV format may be preferred over an RGB
|
||||
format, if an additional conversion step would be required for RGB.
|
||||
|
||||
4. *[optional]* Enumerate ``CAPTURE`` formats via :c:func:`VIDIOC_ENUM_FMT` on
|
||||
the ``CAPTURE`` queue. The client may use this ioctl to discover which
|
||||
alternative raw formats are supported for the current ``OUTPUT`` format and
|
||||
select one of them via :c:func:`VIDIOC_S_FMT`.
|
||||
|
||||
.. note::
|
||||
|
||||
The driver will return only formats supported for the currently selected
|
||||
``OUTPUT`` format and currently set controls, even if more formats may be
|
||||
supported by the decoder in general.
|
||||
|
||||
For example, a decoder may support YUV and RGB formats for
|
||||
resolutions 1920x1088 and lower, but only YUV for higher resolutions (due
|
||||
to hardware limitations). After setting a resolution of 1920x1088 or lower
|
||||
as the ``OUTPUT`` format, :c:func:`VIDIOC_ENUM_FMT` may return a set of
|
||||
YUV and RGB pixel formats, but after setting a resolution higher than
|
||||
1920x1088, the driver will not return RGB pixel formats, since they are
|
||||
unsupported for this resolution.
|
||||
|
||||
5. *[optional]* Choose a different ``CAPTURE`` format than suggested via
|
||||
:c:func:`VIDIOC_S_FMT` on ``CAPTURE`` queue. It is possible for the client to
|
||||
choose a different format than selected/suggested by the driver in
|
||||
:c:func:`VIDIOC_G_FMT`.
|
||||
|
||||
* **Required fields:**
|
||||
|
||||
``type``
|
||||
a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``.
|
||||
|
||||
``pixelformat``
|
||||
a raw pixel format.
|
||||
|
||||
``width``, ``height``
|
||||
frame buffer resolution of the decoded stream; typically unchanged from
|
||||
what was returned with :c:func:`VIDIOC_G_FMT`, but it may be different
|
||||
if the hardware supports composition and/or scaling.
|
||||
|
||||
After performing this step, the client must perform step 3 again in order
|
||||
to obtain up-to-date information about the buffers size and layout.
|
||||
|
||||
6. Allocate source (bytestream) buffers via :c:func:`VIDIOC_REQBUFS` on
|
||||
``OUTPUT`` queue.
|
||||
|
||||
* **Required fields:**
|
||||
|
||||
``count``
|
||||
requested number of buffers to allocate; greater than zero.
|
||||
|
||||
``type``
|
||||
a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``.
|
||||
|
||||
``memory``
|
||||
follows standard semantics.
|
||||
|
||||
* **Return fields:**
|
||||
|
||||
``count``
|
||||
actual number of buffers allocated.
|
||||
|
||||
* If required, the driver will adjust ``count`` to be equal or bigger to the
|
||||
minimum of required number of ``OUTPUT`` buffers for the given format and
|
||||
requested count. The client must check this value after the ioctl returns
|
||||
to get the actual number of buffers allocated.
|
||||
|
||||
7. Allocate destination (raw format) buffers via :c:func:`VIDIOC_REQBUFS` on the
|
||||
``CAPTURE`` queue.
|
||||
|
||||
* **Required fields:**
|
||||
|
||||
``count``
|
||||
requested number of buffers to allocate; greater than zero. The client
|
||||
is responsible for deducing the minimum number of buffers required
|
||||
for the stream to be properly decoded (taking e.g. reference frames
|
||||
into account) and pass an equal or bigger number.
|
||||
|
||||
``type``
|
||||
a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``.
|
||||
|
||||
``memory``
|
||||
follows standard semantics. ``V4L2_MEMORY_USERPTR`` is not supported
|
||||
for ``CAPTURE`` buffers.

||||
|
||||
* **Return fields:**
|
||||
|
||||
``count``
|
||||
adjusted to allocated number of buffers, in case the codec requires
|
||||
more buffers than requested.
|
||||
|
||||
* The driver must adjust count to the minimum of required number of
|
||||
``CAPTURE`` buffers for the current format, stream configuration and
|
||||
requested count. The client must check this value after the ioctl
|
||||
returns to get the number of buffers allocated.
|
||||
|
||||
8. Allocate requests (likely one per ``OUTPUT`` buffer) via
|
||||
:c:func:`MEDIA_IOC_REQUEST_ALLOC` on the media device.
|
||||
|
||||
9. Start streaming on both ``OUTPUT`` and ``CAPTURE`` queues via
|
||||
:c:func:`VIDIOC_STREAMON`.
|
||||
|
||||
Decoding
|
||||
========
|
||||
|
||||
For each frame, the client is responsible for submitting at least one request to
|
||||
which the following is attached:
|
||||
|
||||
* The amount of encoded data expected by the codec for its current
|
||||
configuration, as a buffer submitted to the ``OUTPUT`` queue. Typically, this
|
||||
corresponds to one frame worth of encoded data, but some formats may allow (or
|
||||
require) different amounts per unit.
|
||||
* All the metadata needed to decode the submitted encoded data, in the form of
|
||||
controls relevant to the format being decoded.
|
||||
|
||||
The amount of data and contents of the source ``OUTPUT`` buffer, as well as the
|
||||
controls that must be set on the request, depend on the active coded pixel
|
||||
format and might be affected by codec-specific extended controls, as stated in
|
||||
documentation of each format.
|
||||
|
||||
If there is a possibility that the decoded frame will require one or more
|
||||
decode requests after the current one in order to be produced, then the client
|
||||
must set the ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag on the ``OUTPUT``
|
||||
buffer. This will result in the (potentially partially) decoded ``CAPTURE``
|
||||
buffer not being made available for dequeueing, and reused for the next decode
|
||||
request if the timestamp of the next ``OUTPUT`` buffer has not changed.
|
||||
|
||||
A typical frame would thus be decoded using the following sequence:
|
||||
|
||||
1. Queue an ``OUTPUT`` buffer containing one unit of encoded bytestream data for
|
||||
the decoding request, using :c:func:`VIDIOC_QBUF`.
|
||||
|
||||
* **Required fields:**
|
||||
|
||||
``index``
|
||||
index of the buffer being queued.
|
||||
|
||||
``type``
|
||||
type of the buffer.
|
||||
|
||||
``bytesused``
|
||||
number of bytes taken by the encoded data frame in the buffer.
|
||||
|
||||
``flags``
|
||||
the ``V4L2_BUF_FLAG_REQUEST_FD`` flag must be set. Additionally, if
|
||||
we are not sure that the current decode request is the last one needed
|
||||
to produce a fully decoded frame, then
|
||||
``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` must also be set.
|
||||
|
||||
``request_fd``
|
||||
must be set to the file descriptor of the decoding request.
|
||||
|
||||
``timestamp``
|
||||
must be set to a unique value per frame. This value will be propagated
|
||||
into the decoded frame's buffer and can also be used to use this frame
|
||||
as the reference of another. If using multiple decode requests per
|
||||
frame, then the timestamps of all the ``OUTPUT`` buffers for a given
|
||||
frame must be identical. If the timestamp changes, then the currently
|
||||
held ``CAPTURE`` buffer will be made available for dequeuing and the
|
||||
current request will work on a new ``CAPTURE`` buffer.
|
||||
|
||||
2. Set the codec-specific controls for the decoding request, using
|
||||
:c:func:`VIDIOC_S_EXT_CTRLS`.
|
||||
|
||||
* **Required fields:**
|
||||
|
||||
``which``
|
||||
must be ``V4L2_CTRL_WHICH_REQUEST_VAL``.
|
||||
|
||||
``request_fd``
|
||||
must be set to the file descriptor of the decoding request.
|
||||
|
||||
other fields
|
||||
other fields are set as usual when setting controls. The ``controls``
|
||||
array must contain all the codec-specific controls required to decode
|
||||
a frame.
|
||||
|
||||
.. note::
|
||||
|
||||
It is possible to specify the controls in different invocations of
|
||||
:c:func:`VIDIOC_S_EXT_CTRLS`, or to overwrite a previously set control, as
|
||||
long as ``request_fd`` and ``which`` are properly set. The controls state
|
||||
at the moment of request submission is the one that will be considered.
|
||||
|
||||
.. note::
|
||||
|
||||
The order in which steps 1 and 2 take place is interchangeable.
|
||||
|
||||
3. Submit the request by invoking :c:func:`MEDIA_REQUEST_IOC_QUEUE` on the
|
||||
request FD.
|
||||
|
||||
If the request is submitted without an ``OUTPUT`` buffer, or if some of the
|
||||
required controls are missing from the request, then
|
||||
:c:func:`MEDIA_REQUEST_IOC_QUEUE` will return ``-ENOENT``. If more than one
|
||||
``OUTPUT`` buffer is queued, then it will return ``-EINVAL``.
|
||||
:c:func:`MEDIA_REQUEST_IOC_QUEUE` returning non-zero means that no
|
||||
``CAPTURE`` buffer will be produced for this request.
|
||||
|
||||
``CAPTURE`` buffers must not be part of the request, and are queued
|
||||
independently. They are returned in decode order (i.e. the same order as coded
|
||||
frames were submitted to the ``OUTPUT`` queue).
|
||||
|
||||
Runtime decoding errors are signaled by the dequeued ``CAPTURE`` buffers
|
||||
carrying the ``V4L2_BUF_FLAG_ERROR`` flag. If a decoded reference frame has an
|
||||
error, then all following decoded frames that refer to it also have the
|
||||
``V4L2_BUF_FLAG_ERROR`` flag set, although the decoder will still try to
|
||||
produce (likely corrupted) frames.
|
||||
|
||||
Buffer management while decoding
|
||||
================================
|
||||
Contrary to stateful decoders, a stateless decoder does not perform any kind of
|
||||
buffer management: it only guarantees that dequeued ``CAPTURE`` buffers can be
|
||||
used by the client for as long as they are not queued again. "Used" here
|
||||
encompasses using the buffer for compositing or display.
|
||||
|
||||
A dequeued capture buffer can also be used as the reference frame of another
|
||||
buffer.
|
||||
|
||||
A frame is specified as reference by converting its timestamp into nanoseconds,
|
||||
and storing it into the relevant member of a codec-dependent control structure.
|
||||
The :c:func:`v4l2_timeval_to_ns` function must be used to perform that
|
||||
conversion. The timestamp of a frame can be used to reference it as soon as all
|
||||
its units of encoded data are successfully submitted to the ``OUTPUT`` queue.
|
||||
|
||||
A decoded buffer containing a reference frame must not be reused as a decoding
|
||||
target until all the frames referencing it have been decoded. The safest way to
|
||||
achieve this is to refrain from queueing a reference buffer until all the
|
||||
decoded frames referencing it have been dequeued. However, if the driver can
|
||||
guarantee that buffers queued to the ``CAPTURE`` queue are processed in queued
|
||||
order, then user-space can take advantage of this guarantee and queue a
|
||||
reference buffer when the following conditions are met:
|
||||
|
||||
1. All the requests for frames affected by the reference frame have been
|
||||
queued, and
|
||||
|
||||
2. A sufficient number of ``CAPTURE`` buffers to cover all the decoded
|
||||
referencing frames have been queued.
|
||||
|
||||
When queuing a decoding request, the driver will increase the reference count of
|
||||
all the resources associated with reference frames. This means that the client
|
||||
can e.g. close the DMABUF file descriptors of reference frame buffers if it
|
||||
won't need them afterwards.
|
||||
|
||||
Seeking
|
||||
=======
|
||||
In order to seek, the client just needs to submit requests using input buffers
|
||||
corresponding to the new stream position. It must however be aware that
|
||||
resolution may have changed and follow the dynamic resolution change sequence in
|
||||
that case. Also depending on the codec used, picture parameters (e.g. SPS/PPS
|
||||
for H.264) may have changed and the client is responsible for making sure that a
|
||||
valid state is sent to the decoder.
|
||||
|
||||
The client is then free to ignore any returned ``CAPTURE`` buffer that comes
|
||||
from the pre-seek position.
|
||||
|
||||
Pausing
|
||||
=======
|
||||
|
||||
In order to pause, the client can just cease queuing buffers onto the ``OUTPUT``
|
||||
queue. Without source bytestream data, there is no data to process and the codec
|
||||
will remain idle.
|
||||
|
||||
Dynamic resolution change
|
||||
=========================
|
||||
|
||||
If the client detects a resolution change in the stream, it will need to perform
|
||||
the initialization sequence again with the new resolution:
|
||||
|
||||
1. If the last submitted request resulted in a ``CAPTURE`` buffer being
|
||||
held by the use of the ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag, then the
|
||||
last frame is not available on the ``CAPTURE`` queue. In this case, a
|
||||
``V4L2_DEC_CMD_FLUSH`` command shall be sent. This will make the driver
|
||||
dequeue the held ``CAPTURE`` buffer.
|
||||
|
||||
2. Wait until all submitted requests have completed and dequeue the
|
||||
corresponding output buffers.
|
||||
|
||||
3. Call :c:func:`VIDIOC_STREAMOFF` on both the ``OUTPUT`` and ``CAPTURE``
|
||||
queues.
|
||||
|
||||
4. Free all ``CAPTURE`` buffers by calling :c:func:`VIDIOC_REQBUFS` on the
|
||||
``CAPTURE`` queue with a buffer count of zero.
|
||||
|
||||
5. Perform the initialization sequence again (minus the allocation of
|
||||
``OUTPUT`` buffers), with the new resolution set on the ``OUTPUT`` queue.
|
||||
Note that due to resolution constraints, a different format may need to be
|
||||
picked on the ``CAPTURE`` queue.
|
||||
|
||||
Drain
|
||||
=====
|
||||
|
||||
If the last submitted request resulted in a ``CAPTURE`` buffer being
|
||||
held by the use of the ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag, then the
|
||||
last frame is not available on the ``CAPTURE`` queue. In this case, a
|
||||
``V4L2_DEC_CMD_FLUSH`` command shall be sent. This will make the driver
|
||||
dequeue the held ``CAPTURE`` buffer.
|
||||
|
||||
After that, in order to drain the stream on a stateless decoder, the client
|
||||
just needs to wait until all the submitted requests are completed.

**Input Feeder**
|
||||
|

Input Feeder gets the Bayer frame data from the sensor, it can enable cropping
|
||||
of lines and columns from the frame and then store pixels into device's internal
|
||||
pixel buffer which are ready to readout by following blocks.
|
||||
|
||||
**Bayer Down Scaler**
|
||||
|
||||
Bayer Down Scaler is capable of performing image scaling in Bayer domain, the
|
||||
downscale factor can be configured from 1X to 1/4X in each axis with
|
||||
configuration steps of 0.03125 (1/32).
|
||||
|
||||
**Geometric Distortion Correction**
|
||||
|
||||
Geometric Distortion Correction is used to performe correction of distortions
|
||||
and image filtering. It needs some extra filter and envelop padding pixels to
|
||||
work, so the input resolution of GDC should be larger than the output
|
||||
resolution.
|
||||
|
||||
**YUV Scaler**
|
||||
|
||||
YUV Scaler which similar with BDS, but it is mainly do image down scaling in
|
||||
YUV domain, it can support up to 1/12X down scaling, but it can not be applied
|
||||
to the main output.

the above hardware blocks, for a given input resolution.
|
||||
For a given supported resolution for an input frame, the Input Feeder, Bayer

Down Scaling and GDC blocks should be configured with the supported resolutions.
|
||||
This information can be obtained by looking at the following IPU3 ImgU
|

configuration table.
|
||||
Down Scaler and GDC blocks should be configured with the supported resolutions
|
||||
as each hardware block has its own alignment requirement.
|
||||
|
||||
You must configure the output resolution of the hardware blocks smartly to meet
|
||||
the hardware requirement along with keeping the maximum field of view.
|
||||
The intermediate resolutions can be generated by specific tool and this

information can be obtained by looking at the following IPU3 ImgU configuration

Vimc has a few module parameters to configure the driver. You should pass
|

those arguments to each subdevice, not to the vimc module. For example::

Vimc has a module parameter to configure the driver.

* ``sca_mult=<unsigned int>``
|
||||
|
||||
Image size multiplier factor to be used to multiply both width and
|
||||
height, so the image size will be ``sca_mult^2`` bigger than the
|
||||
original one. Currently, only supports scaling up (the default value
|
||||
is 3).
|
||||
|
||||
* ``vimc_debayer.deb_mean_win_size=<unsigned int>``
|
||||
|
||||
Window size to calculate the mean. Note: the window size needs to be an
|
||||
odd number, as the main pixel stays in the center of the window,
|
||||
otherwise the next odd number is considered (the default value is 3).
