Linux UVC Gadget Driver
|
||||
=======================
|
||||
|
||||
Overview
|
||||
--------
|
||||
The UVC Gadget driver is a driver for hardware on the *device* side of a USB
|
||||
connection. It is intended to run on a Linux system that has USB device-side
|
||||
hardware such as boards with an OTG port.
|
||||
|
||||
On the device system, once the driver is bound it appears as a V4L2 device with
|
||||
the output capability.
|
||||
|
||||
On the host side (once connected via USB cable), a device running the UVC Gadget
|
||||
driver *and controlled by an appropriate userspace program* should appear as a UVC
|
||||
specification compliant camera, and function appropriately with any program
|
||||
designed to handle them. The userspace program running on the device system can
|
||||
queue image buffers from a variety of sources to be transmitted via the USB
|
||||
connection. Typically this would mean forwarding the buffers from a camera sensor
|
||||
peripheral, but the source of the buffer is entirely dependent on the userspace
|
||||
companion program.
|
||||
|
||||
Configuring the device kernel
|
||||
-----------------------------
|
||||
The Kconfig options USB_CONFIGFS, USB_LIBCOMPOSITE, USB_CONFIGFS_F_UVC and
|
||||
USB_F_UVC must be selected to enable support for the UVC gadget.
|
||||
|
||||
Configuring the gadget through configfs
|
||||
---------------------------------------
|
||||
The UVC Gadget expects to be configured through configfs using the UVC function.
|
||||
This allows a significant degree of flexibility, as many of a UVC device's
|
||||
settings can be controlled this way.
|
||||
|
||||
Not all of the available attributes are described here. For a complete enumeration
|
||||
see Documentation/ABI/testing/configfs-usb-gadget-uvc
|
||||
|
||||
Assumptions
|
||||
~~~~~~~~~~~
|
||||
This section assumes that you have mounted configfs at `/sys/kernel/config` and
|
||||
created a gadget as `/sys/kernel/config/usb_gadget/g1`.
|
||||
|
||||
The UVC Function
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||
The first step is to create the UVC function:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# These variables will be assumed throughout the rest of the document
|
||||
CONFIGFS="/sys/kernel/config"
|
||||
GADGET="$CONFIGFS/usb_gadget/g1"
|
||||
FUNCTION="$GADGET/functions/uvc.0"
|
||||
|
||||
mkdir -p $FUNCTION
|
||||
|
||||
Formats and Frames
|
||||
~~~~~~~~~~~~~~~~~~
|
||||
|
||||
You must configure the gadget by telling it which formats you support, as well
|
||||
as the frame sizes and frame intervals that are supported for each format. In
|
||||
the current implementation there is no way for the gadget to refuse to set a
|
||||
format that the host instructs it to set, so it is important that this step is
|
||||
completed *accurately* to ensure that the host never asks for a format that
|
||||
can't be provided.
|
||||
|
||||
Formats are created under the streaming/uncompressed and streaming/mjpeg configfs
|
||||
groups, with the framesizes created under the formats in the following
|
||||
structure:
|
||||
|
||||
::
|
||||
|
||||
uvc.0 +
|
||||
|
|
||||
+ streaming +
|
||||
|
|
||||
+ mjpeg +
|
||||
| |
|
||||
| + mjpeg +
|
||||
| |
|
||||
| + 720p
|
||||
| |
|
||||
| + 1080p
|
||||
|
|
||||
+ uncompressed +
|
||||
|
|
||||
+ yuyv +
|
||||
|
|
||||
+ 720p
|
||||
|
|
||||
+ 1080p
|
||||
|
||||
Each frame can then be configured with a width and height, plus the maximum
|
||||
buffer size required to store a single frame, and finally with the supported
|
||||
frame intervals for that format and framesize. Width and height are enumerated in
|
||||
units of pixels, frame interval in units of 100ns. To create the structure
|
||||
above with 2, 15 and 100 fps frameintervals for each framesize for example you
|
||||
might do:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
create_frame() {
|
||||
# Example usage:
|
||||
# create_frame <width> <height> <group> <format name>
|
||||
|
||||
WIDTH=$1
|
||||
HEIGHT=$2
|
||||
FORMAT=$3
|
||||
NAME=$4
|
||||
|
||||
wdir=$FUNCTION/streaming/$FORMAT/$NAME/${HEIGHT}p
|
||||
|
||||
mkdir -p $wdir
|
||||
echo $WIDTH > $wdir/wWidth
|
||||
echo $HEIGHT > $wdir/wHeight
|
||||
echo $(( $WIDTH * $HEIGHT * 2 )) > $wdir/dwMaxVideoFrameBufferSize
|
||||
cat <<EOF > $wdir/dwFrameInterval
|
||||
666666
|
||||
100000
|
||||
5000000
|
||||
EOF
|
||||
}
|
||||
|
||||
create_frame 1280 720 mjpeg mjpeg
|
||||
create_frame 1920 1080 mjpeg mjpeg
|
||||
create_frame 1280 720 uncompressed yuyv
|
||||
create_frame 1920 1080 uncompressed yuyv
|
||||
|
||||
The only uncompressed format currently supported is YUYV, which is detailed at
|
||||
Documentation/userspace-api/media/v4l/pixfmt-packed.yuv.rst.
|
||||
|
||||
Color Matching Descriptors
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
It's possible to specify some colometry information for each format you create.
|
||||
This step is optional, and default information will be included if this step is
|
||||
skipped; those default values follow those defined in the Color Matching Descriptor
|
||||
section of the UVC specification.
|
||||
|
||||
To create a Color Matching Descriptor, create a configfs item and set its three
|
||||
attributes to your desired settings and then link to it from the format you wish
|
||||
it to be associated with:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# Create a new Color Matching Descriptor
|
||||
|
||||
mkdir $FUNCTION/streaming/color_matching/yuyv
|
||||
pushd $FUNCTION/streaming/color_matching/yuyv
|
||||
|
||||
echo 1 > bColorPrimaries
|
||||
echo 1 > bTransferCharacteristics
|
||||
echo 4 > bMatrixCoefficients
|
||||
|
||||
popd
|
||||
|
||||
# Create a symlink to the Color Matching Descriptor from the format's config item
|
||||
ln -s $FUNCTION/streaming/color_matching/yuyv $FUNCTION/streaming/uncompressed/yuyv
|
||||
|
||||
For details about the valid values, consult the UVC specification. Note that a
|
||||
default color matching descriptor exists and is used by any format which does
|
||||
not have a link to a different Color Matching Descriptor. It's possible to
|
||||
change the attribute settings for the default descriptor, so bear in mind that if
|
||||
you do that you are altering the defaults for any format that does not link to
|
||||
a different one.
|
||||
|
||||
|
||||
Header linking
|
||||
~~~~~~~~~~~~~~
|
||||
|
||||
The UVC specification requires that Format and Frame descriptors be preceded by
|
||||
Headers detailing things such as the number and cumulative size of the different
|
||||
Format descriptors that follow. This and similar operations are acheived in
|
||||
configfs by linking between the configfs item representing the header and the
|
||||
config items representing those other descriptors, in this manner:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
mkdir $FUNCTION/streaming/header/h
|
||||
|
||||
# This section links the format descriptors and their associated frames
|
||||
# to the header
|
||||
cd $FUNCTION/streaming/header/h
|
||||
ln -s ../../uncompressed/yuyv
|
||||
ln -s ../../mjpeg/mjpeg
|
||||
|
||||
# This section ensures that the header will be transmitted for each
|
||||
# speed's set of descriptors. If support for a particular speed is not
|
||||
# needed then it can be skipped here.
|
||||
cd ../../class/fs
|
||||
ln -s ../../header/h
|
||||
cd ../../class/hs
|
||||
ln -s ../../header/h
|
||||
cd ../../class/ss
|
||||
ln -s ../../header/h
|
||||
cd ../../../control
|
||||
mkdir header/h
|
||||
ln -s header/h class/fs
|
||||
ln -s header/h class/ss
|
||||
|
||||
|
||||
Extension Unit Support
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
A UVC Extension Unit (XU) basically provides a distinct unit to which control set
|
||||
and get requests can be addressed. The meaning of those control requests is
|
||||
entirely implementation dependent, but may be used to control settings outside
|
||||
of the UVC specification (for example enabling or disabling video effects). An
|
||||
XU can be inserted into the UVC unit chain or left free-hanging.
|
||||
|
||||
Configuring an extension unit involves creating an entry in the appropriate
|
||||
directory and setting its attributes appropriately, like so:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
mkdir $FUNCTION/control/extensions/xu.0
|
||||
pushd $FUNCTION/control/extensions/xu.0
|
||||
|
||||
# Set the bUnitID of the Processing Unit as the source for this
|
||||
# Extension Unit
|
||||
echo 2 > baSourceID
|
||||
|
||||
# Set this XU as the source of the default output terminal. This inserts
|
||||
# the XU into the UVC chain between the PU and OT such that the final
|
||||
# chain is IT > PU > XU.0 > OT
|
||||
cat bUnitID > ../../terminal/output/default/baSourceID
|
||||
|
||||
# Flag some controls as being available for use. The bmControl field is
|
||||
# a bitmap with each bit denoting the availability of a particular
|
||||
# control. For example to flag the 0th, 2nd and 3rd controls available:
|
||||
echo 0x0d > bmControls
|
||||
|
||||
# Set the GUID; this is a vendor-specific code identifying the XU.
|
||||
echo -e -n "\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f\x10" > guidExtensionCode
|
||||
|
||||
popd
|
||||
|
||||
The bmControls attribute and the baSourceID attribute are multi-value attributes.
|
||||
This means that you may write multiple newline separated values to them. For
|
||||
example to flag the 1st, 2nd, 9th and 10th controls as being available you would
|
||||
need to write two values to bmControls, like so:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
cat << EOF > bmControls
|
||||
0x03
|
||||
0x03
|
||||
EOF
|
||||
|
||||
The multi-value nature of the baSourceID attribute belies the fact that XUs can
|
||||
be multiple-input, though note that this currently has no significant effect.
|
||||
|
||||
The bControlSize attribute reflects the size of the bmControls attribute, and
|
||||
similarly bNrInPins reflects the size of the baSourceID attributes. Both
|
||||
attributes are automatically increased / decreased as you set bmControls and
|
||||
baSourceID. It is also possible to manually increase or decrease bControlSize
|
||||
which has the effect of truncating entries to the new size, or padding entries
|
||||
out with 0x00, for example:
|
||||
|
||||
::
|
||||
|
||||
$ cat bmControls
|
||||
0x03
|
||||
0x05
|
||||
|
||||
$ cat bControlSize
|
||||
2
|
||||
|
||||
$ echo 1 > bControlSize
|
||||
$ cat bmControls
|
||||
0x03
|
||||
|
||||
$ echo 2 > bControlSize
|
||||
$ cat bmControls
|
||||
0x03
|
||||
0x00
|
||||
|
||||
bNrInPins and baSourceID function in the same way.
|
||||
|
||||
Custom Strings Support
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
String descriptors that provide a textual description for various parts of a
|
||||
USB device can be defined in the usual place within USB configfs, and may then
|
||||
be linked to from the UVC function root or from Extension Unit directories to
|
||||
assign those strings as descriptors:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# Create a string descriptor in us-EN and link to it from the function
|
||||
# root. The name of the link is significant here, as it declares this
|
||||
# descriptor to be intended for the Interface Association Descriptor.
|
||||
# Other significant link names at function root are vs0_desc and vs1_desc
|
||||
# For the VideoStreaming Interface 0/1 Descriptors.
|
||||
|
||||
mkdir -p $GADGET/strings/0x409/iad_desc
|
||||
echo -n "Interface Associaton Descriptor" > $GADGET/strings/0x409/iad_desc/s
|
||||
ln -s $GADGET/strings/0x409/iad_desc $FUNCTION/iad_desc
|
||||
|
||||
# Because the link to a String Descriptor from an Extension Unit clearly
|
||||
# associates the two, the name of this link is not significant and may
|
||||
# be set freely.
|
||||
|
||||
mkdir -p $GADGET/strings/0x409/xu.0
|
||||
echo -n "A Very Useful Extension Unit" > $GADGET/strings/0x409/xu.0/s
|
||||
ln -s $GADGET/strings/0x409/xu.0 $FUNCTION/control/extensions/xu.0
|
||||
|
||||
The interrupt endpoint
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The VideoControl interface has an optional interrupt endpoint which is by default
|
||||
disabled. This is intended to support delayed response control set requests for
|
||||
UVC (which should respond through the interrupt endpoint rather than tying up
|
||||
endpoint 0). At present support for sending data through this endpoint is missing
|
||||
and so it is left disabled to avoid confusion. If you wish to enable it you can
|
||||
do so through the configfs attribute:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
echo 1 > $FUNCTION/control/enable_interrupt_ep
|
||||
|
||||
Bandwidth configuration
|
||||
~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
There are three attributes which control the bandwidth of the USB connection.
|
||||
These live in the function root and can be set within limits:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# streaming_interval sets bInterval. Values range from 1..255
|
||||
echo 1 > $FUNCTION/streaming_interval
|
||||
|
||||
# streaming_maxpacket sets wMaxPacketSize. Valid values are 1024/2048/3072
|
||||
echo 3072 > $FUNCTION/streaming_maxpacket
|
||||
|
||||
# streaming_maxburst sets bMaxBurst. Valid values are 1..15
|
||||
echo 1 > $FUNCTION/streaming_maxburst
|
||||
|
||||
|
||||
The values passed here will be clamped to valid values according to the UVC
|
||||
specification (which depend on the speed of the USB connection). To understand
|
||||
how the settings influence bandwidth you should consult the UVC specifications,
|
||||
but a rule of thumb is that increasing the streaming_maxpacket setting will
|
||||
improve bandwidth (and thus the maximum possible framerate), whilst the same is
|
||||
true for streaming_maxburst provided the USB connection is running at SuperSpeed.
|
||||
Increasing streaming_interval will reduce bandwidth and framerate.
|
||||
|
||||
The userspace application
|
||||
-------------------------
|
||||
By itself, the UVC Gadget driver cannot do anything particularly interesting. It
|
||||
must be paired with a userspace program that responds to UVC control requests and
|
||||
fills buffers to be queued to the V4L2 device that the driver creates. How those
|
||||
things are achieved is implementation dependent and beyond the scope of this
|
||||
document, but a reference application can be found at https://gitlab.freedesktop.org/camera/uvc-gadget
