|
||||
|
||||
The Omnivision OV7740 image sensor supports multiple output image
|
||||
size, such as VGA, and QVGA, CIF and any size smaller. It also
|
||||
supports the RAW RGB and YUV output formats.
|
||||
|
||||
The common video interfaces bindings (see video-interfaces.txt) should
|
||||
be used to specify link to the image data receiver. The OV7740 device
|
||||
node should contain one 'port' child node with an 'endpoint' subnode.

- compatible: "ovti,ov7740".
|
||||
- reg: I2C slave address of the sensor.
|
||||
- clocks: Reference to the xvclk input clock.

Remote Controller core
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The remote controller core implements infrastructure to receive and send
|
||||
remote controller keyboard keystrokes and mouse events.
|
||||
|
||||
Every time a key is pressed on a remote controller, a scan code is produced.
|
||||
Also, on most hardware, keeping a key pressed for more than a few dozens of
|
||||
milliseconds produce a repeat key event. That's somewhat similar to what
|
||||
a normal keyboard or mouse is handled internally on Linux\ [#f1]_. So, the
|
||||
remote controller core is implemented on the top of the linux input/evdev
|
||||
interface.
|
||||
|
||||
.. [#f1]
|
||||
|
||||
The main difference is that, on keyboard events, the keyboard controller
|
||||
produces one event for a key press and another one for key release. On
|
||||
infrared-based remote controllers, there's no key release event. Instead,
|
||||
an extra code is produced to indicate key repeats.
|
||||
|
||||
However, most of the remote controllers use infrared (IR) to transmit signals.
|
||||
As there are several protocols used to modulate infrared signals, one
|
||||
important part of the core is dedicated to adjust the driver and the core
|
||||
system to support the infrared protocol used by the emitter.
|
||||
|
||||
The infrared transmission is done by blinking a infrared emitter using a
|
||||
carrier. The carrier can be switched on or off by the IR transmitter
|
||||
hardware. When the carrier is switched on, it is called *PULSE*.
|
||||
When the carrier is switched off, it is called *SPACE*.
|
||||
|
||||
In other words, a typical IR transmission can be viewed as a sequence of
|
||||
*PULSE* and *SPACE* events, each with a given duration.
|
||||
|
||||
The carrier parameters (frequency, duty cycle) and the intervals for
|
||||
*PULSE* and *SPACE* events depend on the protocol.
|
||||
For example, the NEC protocol uses a carrier of 38kHz, and transmissions
|
||||
start with a 9ms *PULSE* and a 4.5ms SPACE. It then transmits 16 bits of
|
||||
scan code, being 8 bits for address (usually it is a fixed number for a
|
||||
given remote controller), followed by 8 bits of code. A bit "1" is modulated
|
||||
with 560µs *PULSE* followed by 1690µs *SPACE* and a bit "0" is modulated
|
||||
with 560µs *PULSE* followed by 560µs *SPACE*.
|
||||
|
||||
At receiver, a simple low-pass filter can be used to convert the received
|
||||
signal in a sequence of *PULSE/SPACE* events, filtering out the carrier
|
||||
frequency. Due to that, the receiver doesn't care about the carrier's
|
||||
actual frequency parameters: all it has to do is to measure the amount
|
||||
of time it receives *PULSE/SPACE* events.
|
||||
So, a simple IR receiver hardware will just provide a sequence of timings
|
||||
for those events to the Kernel. The drivers for hardware with such kind of
|
||||
receivers are identified by ``RC_DRIVER_IR_RAW``, as defined by
|
||||
:c:type:`rc_driver_type`\ [#f2]_. Other hardware come with a
|
||||
microcontroller that decode the *PULSE/SPACE* sequence and return scan
|
||||
codes to the Kernel. Such kind of receivers are identified
|
||||
by ``RC_DRIVER_SCANCODE``.
|
||||
|
||||
.. [#f2]
|
||||
|
||||
The RC core also supports devices that have just IR emitters,
|
||||
without any receivers. Right now, all such devices work only in
|
||||
raw TX mode. Such kind of hardware is identified as
|
||||
``RC_DRIVER_IR_RAW_TX``.
|
||||
|
||||
When the RC core receives events produced by ``RC_DRIVER_IR_RAW`` IR
|
||||
receivers, it needs to decode the IR protocol, in order to obtain the
|
||||
corresponding scan code. The protocols supported by the RC core are
|
||||
defined at enum :c:type:`rc_proto`.
|
||||
|
||||
When the RC code receives a scan code (either directly, by a driver
|
||||
of the type ``RC_DRIVER_SCANCODE``, or via its IR decoders), it needs
|
||||
to convert into a Linux input event code. This is done via a mapping
|
||||
table.
|
||||
|
||||
The Kernel has support for mapping tables available on most media
|
||||
devices. It also supports loading a table in runtime, via some
|
||||
sysfs nodes. See the :ref:`RC userspace API <Remote_controllers_Intro>`
|
||||
for more details.

@ -5,27 +5,68 @@ V4L2 events
|
|||
The V4L2 events provide a generic way to pass events to user space.
|
||||
The driver must use :c:type:`v4l2_fh` to be able to support V4L2 events.
|
||||
|
||||
Events are defined by a type and an optional ID. The ID may refer to a V4L2
|
||||
object such as a control ID. If unused, then the ID is 0.
|
||||
Events are subscribed per-filehandle. An event specification consists of a
|
||||
``type`` and is optionally associated with an object identified through the
|
||||
``id`` field. If unused, then the ``id`` is 0. So an event is uniquely
|
||||
identified by the ``(type, id)`` tuple.
|
||||
|
||||
When the user subscribes to an event the driver will allocate a number of
|
||||
kevent structs for that event. So every (type, ID) event tuple will have
|
||||
its own set of kevent structs. This guarantees that if a driver is generating
|
||||
lots of events of one type in a short time, then that will not overwrite
|
||||
events of another type.
|
||||
The :c:type:`v4l2_fh` struct has a list of subscribed events on its
|
||||
``subscribed`` field.
|
||||
|
||||
But if you get more events of one type than the number of kevents that were
|
||||
reserved, then the oldest event will be dropped and the new one added.
|
||||
When the user subscribes to an event, a :c:type:`v4l2_subscribed_event`
|
||||
struct is added to :c:type:`v4l2_fh`\ ``.subscribed``, one for every
|
||||
subscribed event.
|
||||
|
||||
Each :c:type:`v4l2_subscribed_event` struct ends with a
|
||||
:c:type:`v4l2_kevent` ringbuffer, with the size given by the caller
|
||||
of :c:func:`v4l2_event_subscribe`. This ringbuffer is used to store any events
|
||||
raised by the driver.
|
||||
|
||||
So every ``(type, ID)`` event tuple will have its own
|
||||
:c:type:`v4l2_kevent` ringbuffer. This guarantees that if a driver is
|
||||
generating lots of events of one type in a short time, then that will
|
||||
not overwrite events of another type.
|
||||
|
||||
But if you get more events of one type than the size of the
|
||||
:c:type:`v4l2_kevent` ringbuffer, then the oldest event will be dropped
|
||||
and the new one added.
|
||||
|
||||
The :c:type:`v4l2_kevent` struct links into the ``available``
|
||||
list of the :c:type:`v4l2_fh` struct so :ref:`VIDIOC_DQEVENT` will
|
||||
know which event to dequeue first.
|
||||
|
||||
Finally, if the event subscription is associated with a particular object
|
||||
such as a V4L2 control, then that object needs to know about that as well
|
||||
so that an event can be raised by that object. So the ``node`` field can
|
||||
be used to link the :c:type:`v4l2_subscribed_event` struct into a list of
|
||||
such objects.
|
||||
|
||||
So to summarize:
|
||||
|
||||
- struct :c:type:`v4l2_fh` has two lists: one of the ``subscribed`` events,
|
||||
and one of the ``available`` events.
|
||||
|
||||
- struct :c:type:`v4l2_subscribed_event` has a ringbuffer of raised
|
||||
(pending) events of that particular type.
|
||||
|
||||
- If struct :c:type:`v4l2_subscribed_event` is associated with a specific
|
||||
object, then that object will have an internal list of
|
||||
struct :c:type:`v4l2_subscribed_event` so it knows who subscribed an
|
||||
event to that object.
|
||||
|
||||
Furthermore, the internal struct :c:type:`v4l2_subscribed_event` has
|
||||
``merge()`` and ``replace()`` callbacks which drivers can set. These
|
||||
callbacks are called when a new event is raised and there is no more room.
|
||||
|
||||
The ``replace()`` callback allows you to replace the payload of the old event
|
||||
with that of the new event, merging any relevant data from the old payload
|
||||
into the new payload that replaces it. It is called when this event type has
|
||||
only one kevent struct allocated. The ``merge()`` callback allows you to merge
|
||||
the oldest event payload into that of the second-oldest event payload. It is
|
||||
called when there are two or more kevent structs allocated.
|
||||
a ringbuffer with size is one, i.e. only one event can be stored in the
|
||||
ringbuffer.
|
||||
|
||||
The ``merge()`` callback allows you to merge the oldest event payload into
|
||||
that of the second-oldest event payload. It is called when
|
||||
the ringbuffer has size is greater than one.
|
||||
|
||||
This way no status information is lost, just the intermediate steps leading
|
||||
up to that state.

Arguments
|
||||
=========
|
||||
|
||||
``fd``
|
||||
File descriptor returned by :ref:`open() <dmx_fopen>`.
|
||||
|
||||
``argp``
|
||||
Pointer to struct :c:type:`dmx_exportbuffer`.
|
||||
|
||||
|
||||
Description
|
||||
===========
|
||||
|
||||
This ioctl is an extension to the memory mapping I/O method.
|
||||
It can be used to export a buffer as a DMABUF file at any time after
|
||||
buffers have been allocated with the :ref:`DMX_REQBUFS` ioctl.
|
||||
|
||||
To export a buffer, applications fill struct :c:type:`dmx_exportbuffer`.
|
||||
Applications must set the ``index`` field. Valid index numbers
|
||||
range from zero to the number of buffers allocated with :ref:`DMX_REQBUFS`
|
||||
(struct :c:type:`dmx_requestbuffers` ``count``) minus one.
|
||||
Additional flags may be posted in the ``flags`` field. Refer to a manual
|
||||
for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
|
||||
and O_RDWR are supported.
|
||||
All other fields must be set to zero. In the
|
||||
case of multi-planar API, every plane is exported separately using
|
||||
multiple :ref:`DMX_EXPBUF` calls.
|
||||
|
||||
After calling :ref:`DMX_EXPBUF` the ``fd`` field will be set by a
|
||||
driver, on success. This is a DMABUF file descriptor. The application may
|
||||
pass it to other DMABUF-aware devices. It is recommended to close a DMABUF
|
||||
file when it is no longer used to allow the associated memory to be reclaimed.

|
||||
Arguments
|
||||
=========
|
||||
|
||||
``start``
|
||||
Map the buffer to this address in the application's address space.
|
||||
When the ``MAP_FIXED`` flag is specified, ``start`` must be a
|
||||
multiple of the pagesize and mmap will fail when the specified
|
||||
address cannot be used. Use of this option is discouraged;
|
||||
applications should just specify a ``NULL`` pointer here.
|
||||
|
||||
``length``
|
||||
Length of the memory area to map. This must be a multiple of the
|
||||
DVB packet length (188, on most drivers).
|
||||
|
||||
``prot``
|
||||
The ``prot`` argument describes the desired memory protection.
|
||||
Regardless of the device type and the direction of data exchange it
|
||||
should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
|
||||
and write access to image buffers. Drivers should support at least
|
||||
this combination of flags.
|
||||
|
||||
``flags``
|
||||
The ``flags`` parameter specifies the type of the mapped object,
|
||||
mapping options and whether modifications made to the mapped copy of
|
||||
the page are private to the process or are to be shared with other
|
||||
references.
|
||||
|
||||
``MAP_FIXED`` requests that the driver selects no other address than
|
||||
the one specified. If the specified address cannot be used,
|
||||
:ref:`mmap() <dmx-mmap>` will fail. If ``MAP_FIXED`` is specified,
|
||||
``start`` must be a multiple of the pagesize. Use of this option is
|
||||
discouraged.
|
||||
|
||||
One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
|
||||
``MAP_SHARED`` allows applications to share the mapped memory with
|
||||
other (e. g. child-) processes.
|
||||
|
||||
.. note::
|
||||
|
||||
The Linux Digital TV applications should not set the
|
||||
``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
|
||||
flags.
|
||||
|
||||
``fd``
|
||||
File descriptor returned by :ref:`open() <dmx_fopen>`.
|
||||
|
||||
``offset``
|
||||
Offset of the buffer in device memory, as returned by
|
||||
:ref:`DMX_QUERYBUF` ioctl.
|
||||
|
||||
|
||||
Description
|
||||
===========
|
||||
|
||||
The :ref:`mmap() <dmx-mmap>` function asks to map ``length`` bytes starting at
|
||||
``offset`` in the memory of the device specified by ``fd`` into the
|
||||
application address space, preferably at address ``start``. This latter
|
||||
address is a hint only, and is usually specified as 0.
|
||||
|
||||
Suitable length and offset parameters are queried with the
|
||||
:ref:`DMX_QUERYBUF` ioctl. Buffers must be allocated with the
|
||||
:ref:`DMX_REQBUFS` ioctl before they can be queried.
|
||||

|

Arguments
|
||||
=========
|
||||
|
||||
``fd``
|
||||
File descriptor returned by :ref:`open() <dmx_fopen>`.
|
||||
|
||||
``argp``
|
||||
Pointer to struct :c:type:`dmx_buffer`.
|
||||
|
||||
|
||||
Description
|
||||
===========
|
||||
|
||||
Applications call the ``DMX_QBUF`` ioctl to enqueue an empty
|
||||
(capturing) or filled (output) buffer in the driver's incoming queue.
|
||||
The semantics depend on the selected I/O method.
|
||||
|
||||
To enqueue a buffer applications set the ``index`` field. Valid index
|
||||
numbers range from zero to the number of buffers allocated with
|
||||
:ref:`DMX_REQBUFS` (struct :c:type:`dmx_requestbuffers` ``count``) minus
|
||||
one. The contents of the struct :c:type:`dmx_buffer` returned
|
||||
by a :ref:`DMX_QUERYBUF` ioctl will do as well.
|
||||
|
||||
When ``DMX_QBUF`` is called with a pointer to this structure, it locks the
|
||||
memory pages of the buffer in physical memory, so they cannot be swapped
|
||||
out to disk. Buffers remain locked until dequeued, until the
|
||||
the device is closed.
|
||||
|
||||
Applications call the ``DMX_DQBUF`` ioctl to dequeue a filled
|
||||
(capturing) buffer from the driver's outgoing queue. They just set the ``reserved`` field array to zero. When ``DMX_DQBUF`` is called with a
|
||||
pointer to this structure, the driver fills the remaining fields or
|
||||
returns an error code.
|
||||
|
||||
By default ``DMX_DQBUF`` blocks when no buffer is in the outgoing
|
||||
queue. When the ``O_NONBLOCK`` flag was given to the
|
||||
:ref:`open() <dmx_fopen>` function, ``DMX_DQBUF`` returns
|
||||
immediately with an ``EAGAIN`` error code when no buffer is available.
|
||||
|
||||
The struct :c:type:`dmx_buffer` structure is specified in
|
||||
:ref:`buffer`.
|
||||
|
||||
|
||||
Return Value
|
||||
============
|
||||
|
||||
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
||||
appropriately. The generic error codes are described at the
|
||||
:ref:`Generic Error Codes <gen-errors>` chapter.
|
||||
|
||||
EAGAIN
|
||||
Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
|
||||
buffer was in the outgoing queue.

Arguments
|
||||
=========
|
||||
|
||||
``fd``
|
||||
File descriptor returned by :ref:`open() <dmx_fopen>`.
|

|

``argp``
|

Pointer to struct :c:type:`dmx_requestbuffers`.
|
||||
|
||||
Description
|
||||
===========
|
||||
|
||||
This ioctl is used to initiate a memory mapped or DMABUF based demux I/O.
|
||||
|
||||
Memory mapped buffers are located in device memory and must be allocated
|
||||
with this ioctl before they can be mapped into the application's address
|
||||
space. User buffers are allocated by applications themselves, and this
|
||||
ioctl is merely used to switch the driver into user pointer I/O mode and
|
||||
to setup some internal structures. Similarly, DMABUF buffers are
|
||||
allocated by applications through a device driver, and this ioctl only
|
||||
configures the driver into DMABUF I/O mode without performing any direct
|
||||
allocation.
|
||||
|
||||
To allocate device buffers applications initialize all fields of the
|
||||
struct :c:type:`dmx_requestbuffers` structure. They set the ``count`` field
|
||||
to the desired number of buffers, and ``size`` to the size of each
|
||||
buffer.
|
||||
|
||||
When the ioctl is called with a pointer to this structure, the driver will
|
||||
attempt to allocate the requested number of buffers and it stores the actual
|
||||
number allocated in the ``count`` field. The ``count`` can be smaller than the number requested, even zero, when the driver runs out of free memory. A larger
|
||||
number is also possible when the driver requires more buffers to
|
||||
function correctly. The actual allocated buffer size can is returned
|
||||
at ``size``, and can be smaller than what's requested.
|
||||
|
||||
When this I/O method is not supported, the ioctl returns an ``EOPNOTSUPP``
|
||||
error code.
|
||||
|
||||
Applications can call :ref:`DMX_REQBUFS` again to change the number of
|
||||
buffers, however this cannot succeed when any buffers are still mapped.
|
||||
A ``count`` value of zero frees all buffers, after aborting or finishing
|
||||
any DMA in progress.
|
||||
|
||||
|
||||
Return Value
|
||||
============
|
||||
|
||||
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
||||
appropriately. The generic error codes are described at the
|
||||
:ref:`Generic Error Codes <gen-errors>` chapter.

|
|||
LIRC supports some modes of receiving and sending IR codes, as shown
|
||||
on the following table.
|
||||
|
||||
.. _lirc-mode-scancode:
|
||||
.. _lirc-scancode-flag-toggle:
|
||||
.. _lirc-scancode-flag-repeat:
|
||||
|
||||
``LIRC_MODE_SCANCODE``
|
||||
|
||||
This mode is for both sending and receiving IR.
|
||||
|
||||
For transmitting (aka sending), create a ``struct lirc_scancode`` with
|
||||
the desired scancode set in the ``scancode`` member, :c:type:`rc_proto`
|
||||
set the IR protocol, and all other members set to 0. Write this struct to
|
||||
the lirc device.
|
||||
|
||||
For receiving, you read ``struct lirc_scancode`` from the lirc device,
|
||||
with ``scancode`` set to the received scancode and the IR protocol
|
||||
:c:type:`rc_proto`. If the scancode maps to a valid key code, this is set
|
||||
in the ``keycode`` field, else it is set to ``KEY_RESERVED``.
|
||||
|
||||
The ``flags`` can have ``LIRC_SCANCODE_FLAG_TOGGLE`` set if the toggle
|
||||
bit is set in protocols that support it (e.g. rc-5 and rc-6), or
|
||||
``LIRC_SCANCODE_FLAG_REPEAT`` for when a repeat is received for protocols
|
||||
that support it (e.g. nec).
|
||||
|
||||
In the Sanyo and NEC protocol, if you hold a button on remote, rather than
|
||||
repeating the entire scancode, the remote sends a shorter message with
|
||||
no scancode, which just means button is held, a "repeat". When this is
|
||||
received, the ``LIRC_SCANCODE_FLAG_REPEAT`` is set and the scancode and
|
||||
keycode is repeated.
|
||||
|
||||
With nec, there is no way to distinguish "button hold" from "repeatedly
|
||||
pressing the same button". The rc-5 and rc-6 protocols have a toggle bit.
|
||||
When a button is released and pressed again, the toggle bit is inverted.
|
||||
If the toggle bit is set, the ``LIRC_SCANCODE_FLAG_TOGGLE`` is set.
|
||||
|
||||
The ``timestamp`` field is filled with the time nanoseconds
|
||||
(in ``CLOCK_MONOTONIC``) when the scancode was decoded.

UVC Payload Header Data
|
||||
|
||||
|
||||
Description
|
||||
===========
|
||||
|
||||
This format describes standard UVC metadata, extracted from UVC packet headers
|
||||
and provided by the UVC driver through metadata video nodes. That data includes
|
||||
exact copies of the standard part of UVC Payload Header contents and auxiliary
|
||||
timing information, required for precise interpretation of timestamps, contained
|
||||
in those headers. See section "2.4.3.3 Video and Still Image Payload Headers" of
|
||||
the "UVC 1.5 Class specification" for details.
|
||||
|
||||
Each UVC payload header can be between 2 and 12 bytes large. Buffers can
|
||||
contain multiple headers, if multiple such headers have been transmitted by the
|
||||
camera for the respective frame. However, the driver may drop headers when the
|
||||
buffer is full, when they contain no useful information (e.g. those without the
|
||||
SCR field or with that field identical to the previous header), or generally to
|
||||
perform rate limiting when the device sends a large number of headers.
|
||||
|
||||
Each individual block contains the following fields:

10-bit Bayer formats
|

Description
|
||||
===========
|
||||
|
||||
These four pixel formats are used by Intel IPU3 driver, they are raw
|
||||
sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
|
||||
to 32 bytes leaving 6 most significant bits padding in the last byte.
|
||||
The format is little endian.
|
||||
|
||||
In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
|
||||
Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.
