SPDX-License-Identifier: GPL-2.0 - -The cpia2 driver -================ - -Authors: Peter Pregler <Peter_Pregler@email.com>, -Scott J. Bertin <scottbertin@yahoo.com>, and -Jarl Totland <Jarl.Totland@bdc.no> for the original cpia driver, which -this one was modelled from. - -Introduction ------------- - -This is a driver for STMicroelectronics's CPiA2 (second generation -Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG -stream at up to vga size. It implements the Video4Linux interface as much as -possible. Since the V4L interface does not support compressed formats, only -an mjpeg enabled application can be used with the camera. We have modified the -gqcam application to view this stream. - -The driver is implemented as two kernel modules. The cpia2 module -contains the camera functions and the V4L interface. The cpia2_usb module -contains usb specific functions. The main reason for this was the size of the -module was getting out of hand, so I separated them. It is not likely that -there will be a parallel port version. - -Features --------- - -- Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos - sensors. I only have the vga sensor, so can't test the other. -- Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between. - VGA and QVGA are the native image sizes for the VGA camera. CIF is done - in the coprocessor by scaling QVGA. All other sizes are done by clipping. -- Palette: YCrCb, compressed with MJPEG. -- Some compression parameters are settable. -- Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA). -- Adjust brightness, color, contrast while streaming. -- Flicker control settable for 50 or 60 Hz mains frequency. - -Making and installing the stv672 driver modules ------------------------------------------------ - -Requirements -~~~~~~~~~~~~ - -Video4Linux must be either compiled into the kernel or -available as a module. Video4Linux2 is automatically detected and made -available at compile time. - -Setup -~~~~~ - -Use ``modprobe cpia2`` to load and ``modprobe -r cpia2`` to unload.

If the compression engine is able to -keep up with the frame rate, the maximum image size is given by the table -below. - -The compression engine starts out at maximum compression, and will -increase image quality until it is close to the size in the table. As long -as the compression engine can keep up with the frame rate, after a short time -the images will all be about the size in the table, regardless of resolution. - -At low alternate settings, the compression engine may not be able to -compress the image enough and will reduce the frame rate by producing larger -images. - -The default of 68k should be good for most users. This will handle -any alternate at frame rates down to 15fps. For lower frame rates, it may -be necessary to increase the buffer size to avoid having frames dropped due -to insufficient space. - -========== ========== ======== ===== -Alternate bytes/ms 15fps 30fps -========== ========== ======== ===== - 2 128 8533 4267 - 3 384 25600 12800 - 4 640 42667 21333 - 5 768 51200 25600 - 6 896 59733 29867 - 7 1023 68200 34100 -========== ========== ======== ===== - -Table: Image size(bytes) - - -How many buffers should I use? -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -For normal streaming, 3 should give the best results. With only 2, -it is possible for the camera to finish sending one image just after a -program has started reading the other. If this happens, the driver must drop -a frame. The exception to this is if you have a heavily loaded machine. In -this case use 2 buffers. You are probably not reading at the full frame rate. -If the camera can send multiple images before a read finishes, it could -overwrite the third buffer before the read finishes, leading to a corrupt -image. Single and double buffering have extra checks to avoid overwriting. - -Using the camera -~~~~~~~~~~~~~~~~ - -We are providing a modified gqcam application to view the output. In -order to avoid confusion, here it is called mview. There is also the qx5view -program which can also control the lights on the qx5 microscope. MJPEG Tools -(http://mjpeg.sourceforge.net) can also be used to record from the camera. diff --git a/Documentation/admin-guide/media/dvb-drivers.rst b/Documentation/admin-guide/media/dvb-drivers.rst index 8df637c375f9..66fa4edd0606 100644 --- a/Documentation/admin-guide/media/dvb-drivers.rst +++ b/Documentation/admin-guide/media/dvb-drivers.rst @@ -13,4 +13,3 @@ Digital TV driver-specific documentation opera-firmware technisat ttusb-dec - zr364xx diff --git a/Documentation/admin-guide/media/meye.rst b/Documentation/admin-guide/media/meye.rst deleted file mode 100644 index 9098a1e65f8b..000000000000 --- a/Documentation/admin-guide/media/meye.rst +++ /dev/null @@ -1,93 +0,0 @@ -..

See cpia2.sf.net for 2.4 support. - -Programmer's overview of cpia2 driver -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Cpia2 is the second generation video coprocessor from VLSI Vision Ltd (now a -division of ST Microelectronics). There are two versions. The first is the -STV0672, which is capable of up to 30 frames per second (fps) in frame sizes -up to CIF, and 15 fps for VGA frames. The STV0676 is an improved version, -which can handle up to 30 fps VGA. Both coprocessors can be attached to two -CMOS sensors - the vvl6410 CIF sensor and the vvl6500 VGA sensor. These will -be referred to as the 410 and the 500 sensors, or the CIF and VGA sensors. - -The two chipsets operate almost identically. The core is an 8051 processor, -running two different versions of firmware. The 672 runs the VP4 video -processor code, the 676 runs VP5. There are a few differences in register -mappings for the two chips. In these cases, the symbols defined in the -header files are marked with VP4 or VP5 as part of the symbol name. - -The cameras appear externally as three sets of registers. Setting register -values is the only way to control the camera. Some settings are -interdependant, such as the sequence required to power up the camera. I will -try to make note of all of these cases. - -The register sets are called blocks. Block 0 is the system block. This -section is always powered on when the camera is plugged in. It contains -registers that control housekeeping functions such as powering up the video -processor. The video processor is the VP block. These registers control -how the video from the sensor is processed. Examples are timing registers, -user mode (vga, qvga), scaling, cropping, framerates, and so on. The last -block is the video compressor (VC). The video stream sent from the camera is -compressed as Motion JPEG (JPEGA). The VC controls all of the compression -parameters. Looking at the file cpia2_registers.h, you can get a full view -of these registers and the possible values for most of them. - -One or more registers can be set or read by sending a usb control message to -the camera. There are three modes for this. Block mode requests a number -of contiguous registers. Random mode reads or writes random registers with -a tuple structure containing address/value pairs. The repeat mode is only -used by VP4 to load a firmware patch. It contains a starting address and -a sequence of bytes to be written into a gpio port. diff --git a/Documentation/driver-api/media/drivers/index.rst b/Documentation/driver-api/media/drivers/index.rst index 32406490557c..61d64366ab51 100644 --- a/Documentation/driver-api/media/drivers/index.rst +++ b/Documentation/driver-api/media/drivers/index.rst @@ -13,7 +13,6 @@ Video4Linux (V4L) drivers :maxdepth: 5 bttv-devel - cpia2_devel cx2341x-devel cx88-devel davinci-vpbe-devel diff --git a/Documentation/driver-api/media/v4l2-subdev.rst b/Documentation/driver-api/media/v4l2-subdev.rst index 6f8d79926aa5..260cfa8c3f3d 100644 --- a/Documentation/driver-api/media/v4l2-subdev.rst +++ b/Documentation/driver-api/media/v4l2-subdev.rst @@ -593,6 +593,14 @@ before calling v4l2_subdev_init_finalize(): This shares the driver's private mutex between the controls and the states. +Streams, multiplexed media pads and internal routing +---------------------------------------------------- + +A subdevice driver can implement support for multiplexed streams by setting +the V4L2_SUBDEV_FL_STREAMS subdev flag and implementing support for +centrally managed subdev active state, routing and stream based +configuration. + V4L2 sub-device functions and data structures --------------------------------------------- diff --git a/Documentation/userspace-api/media/drivers/index.rst b/Documentation/userspace-api/media/drivers/index.rst index 915dbf0f4db5..6708d649afd7 100644 --- a/Documentation/userspace-api/media/drivers/index.rst +++ b/Documentation/userspace-api/media/drivers/index.rst @@ -37,7 +37,6 @@ For more details see the file COPYING in the source distribution of Linux. dw100 imx-uapi max2175 - meye-uapi omap3isp-uapi st-vgxy61 uvcvideo diff --git a/Documentation/userspace-api/media/drivers/meye-uapi.rst b/Documentation/userspace-api/media/drivers/meye-uapi.rst deleted file mode 100644 index 66b1c142f920..000000000000 --- a/Documentation/userspace-api/media/drivers/meye-uapi.rst +++ /dev/null @@ -1,53 +0,0 @@ -..

A subdev can do stream processing and split a stream into +two or compose two streams into one, but the inputs and outputs for the +subdev are still a single stream per pad. + +Some hardware, e.g. MIPI CSI-2, support multiplexed streams, that is, multiple +data streams are transmitted on the same bus, which is represented by a media +link connecting a transmitter source pad with a sink pad on the receiver. For +example, a camera sensor can produce two distinct streams, a pixel stream and a +metadata stream, which are transmitted on the multiplexed data bus, represented +by a media link which connects the single sensor's source pad with the receiver +sink pad. The stream-aware receiver will de-multiplex the streams received on +the its sink pad and allows to route them individually to one of its source +pads. + +Subdevice drivers that support multiplexed streams are compatible with +non-multiplexed subdev drivers, but, of course, require a routing configuration +where the link between those two types of drivers contains only a single +stream. + +Understanding streams +^^^^^^^^^^^^^^^^^^^^^ + +A stream is a stream of content (e.g. pixel data or metadata) flowing through +the media pipeline from a source (e.g. a sensor) towards the final sink (e.g. a +receiver and demultiplexer in a SoC). Each media link carries all the enabled +streams from one end of the link to the other, and sub-devices have routing +tables which describe how the incoming streams from sink pads are routed to the +source pads. + +A stream ID is a media pad-local identifier for a stream. Streams IDs of +the same stream must be equal on both ends of a link. In other words, +a particular stream ID must exist on both sides of a media +link, but another stream ID can be used for the same stream at the other side +of the sub-device. + +A stream at a specific point in the media pipeline is identified by the +sub-device and a (pad, stream) pair. For sub-devices that do not support +multiplexed streams the 'stream' field is always 0. + +Interaction between routes, streams, formats and selections +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The addition of streams to the V4L2 sub-device interface moves the sub-device +formats and selections from pads to (pad, stream) pairs. Besides the +usual pad, also the stream ID needs to be provided for setting formats and +selections. The order of configuring formats and selections along a stream is +the same as without streams (see :ref:`format-propagation`). + +Instead of the sub-device wide merging of streams from all sink pads +towards all source pads, data flows for each route are separate from each +other. Any number of routes from streams on sink pads towards streams on +source pads is allowed, to the extent supported by drivers. For every +stream on a source pad, however, only a single route is allowed. + +Any configurations of a stream within a pad, such as format or selections, +are independent of similar configurations on other streams. This is +subject to change in the future. + +Configuring streams +^^^^^^^^^^^^^^^^^^^ + +The configuration of the streams is done individually for each sub-device and +the validity of the streams between sub-devices is validated when the pipeline +is started. + +There are three steps in configuring the streams: + +1) Set up links. Connect the pads between sub-devices using the :ref:`Media +Controller API <media_controller>` + +2) Streams. Streams are declared and their routing is configured by +setting the routing table for the sub-device using +:ref:`VIDIOC_SUBDEV_S_ROUTING <VIDIOC_SUBDEV_G_ROUTING>` ioctl. Note that +setting the routing table will reset formats and selections in the +sub-device to default values. + +3) Configure formats and selections. Formats and selections of each stream +are configured separately as documented for plain sub-devices in +:ref:`format-propagation`. The stream ID is set to the same stream ID +associated with either sink or source pads of routes configured using the +:ref:`VIDIOC_SUBDEV_S_ROUTING <VIDIOC_SUBDEV_G_ROUTING>` ioctl. + +Multiplexed streams setup example +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +A simple example of a multiplexed stream setup might be as follows: + +- Two identical sensors (Sensor A and Sensor B). Each sensor has a single source + pad (pad 0) which carries a pixel data stream. + +- Multiplexer bridge (Bridge). The bridge has two sink pads, connected to the + sensors (pads 0, 1), and one source pad (pad 2), which outputs two streams. + +- Receiver in the SoC (Receiver). The receiver has a single sink pad (pad 0), + connected to the bridge, and two source pads (pads 1-2), going to the DMA + engine. The receiver demultiplexes the incoming streams to the source pads. + +- DMA Engines in the SoC (DMA Engine), one for each stream. Each DMA engine is + connected to a single source pad in the receiver. + +The sensors, the bridge and the receiver are modeled as V4L2 sub-devices, +exposed to userspace via /dev/v4l-subdevX device nodes. The DMA engines are +modeled as V4L2 devices, exposed to userspace via /dev/videoX nodes. + +To configure this pipeline, the userspace must take the following steps: + +1) Set up media links between entities: connect the sensors to the bridge, +bridge to the receiver, and the receiver to the DMA engines.
