-
-
-4. Overview and features
-========================
-This driver attempts to support the video interface of the devices assembling
-the SONiX SN9C101, SN9C102, SN9C103, SN9C105 and SN9C120 PC Camera Controllers
-("SN9C1xx" from now on).
-
-The driver relies on the Video4Linux2 and USB core modules. It has been
-designed to run properly on SMP systems as well.
-
-The latest version of the SN9C1xx driver can be found at the following URL:
-http://www.linux-projects.org/
-
-Some of the features of the driver are:
-
-- full compliance with the Video4Linux2 API (see also "Notes for V4L2
- application developers" paragraph);
-- available mmap or read/poll methods for video streaming through isochronous
- data transfers;
-- automatic detection of image sensor;
-- support for built-in microphone interface;
-- support for any window resolutions and optional panning within the maximum
- pixel area of image sensor;
-- image downscaling with arbitrary scaling factors from 1, 2 and 4 in both
- directions (see "Notes for V4L2 application developers" paragraph);
-- two different video formats for uncompressed or compressed data in low or
- high compression quality (see also "Notes for V4L2 application developers"
- and "Video frame formats" paragraphs);
-- full support for the capabilities of many of the possible image sensors that
- can be connected to the SN9C1xx bridges, including, for instance, red, green,
- blue and global gain adjustments and exposure (see "Supported devices"
- paragraph for details);
-- use of default color settings for sunlight conditions;
-- dynamic I/O interface for both SN9C1xx and image sensor control and
- monitoring (see "Optional device control through 'sysfs'" paragraph);
-- dynamic driver control thanks to various module parameters (see "Module
- parameters" paragraph);
-- up to 64 cameras can be handled at the same time; they can be connected and
- disconnected from the host many times without turning off the computer, if
- the system supports hotplugging;
-- no known bugs.
-
-
-5. Module dependencies
-======================
-For it to work properly, the driver needs kernel support for Video4Linux and
-USB.
-
-The following options of the kernel configuration file must be enabled and
-corresponding modules must be compiled:
-
- # Multimedia devices
- #
- CONFIG_VIDEO_DEV=m
-
-To enable advanced debugging functionality on the device through /sysfs:
-
- # Multimedia devices
- #
- CONFIG_VIDEO_ADV_DEBUG=y
-
- # USB support
- #
- CONFIG_USB=m
-
-In addition, depending on the hardware being used, the modules below are
-necessary:
-
- # USB Host Controller Drivers
- #
- CONFIG_USB_EHCI_HCD=m
- CONFIG_USB_UHCI_HCD=m
- CONFIG_USB_OHCI_HCD=m
-
-The SN9C103, SN9c105 and SN9C120 controllers also provide a built-in microphone
-interface. It is supported by the USB Audio driver thanks to the ALSA API:
-
- # Sound
- #
- CONFIG_SOUND=y
-
- # Advanced Linux Sound Architecture
- #
- CONFIG_SND=m
-
- # USB devices
- #
- CONFIG_SND_USB_AUDIO=m
-
-And finally:
-
- # USB Multimedia devices
- #
- CONFIG_USB_SN9C102=m
-
-
-6. Module loading
-=================
-To use the driver, it is necessary to load the "sn9c102" module into memory
-after every other module required: "videodev", "v4l2_common", "compat_ioctl32",
-"usbcore" and, depending on the USB host controller you have, "ehci-hcd",
-"uhci-hcd" or "ohci-hcd".
-
-Loading can be done as shown below:
-
- [root@localhost home]# modprobe sn9c102
-
-Note that the module is called "sn9c102" for historic reasons, although it
-does not just support the SN9C102.
-
-At this point all the devices supported by the driver and connected to the USB
-ports should be recognized. You can invoke "dmesg" to analyze kernel messages
-and verify that the loading process has gone well:
-
- [user@localhost home]$ dmesg
-
-or, to isolate all the kernel messages generated by the driver:
-
- [user@localhost home]$ dmesg | grep sn9c102
-
-
-7. Module parameters
-====================
-Module parameters are listed below:
--------------------------------------------------------------------------------
-Name: video_nr
-Type: short array (min = 0, max = 64)
-Syntax: <-1|n[,...]>
-Description: Specify V4L2 minor mode number:
- -1 = use next available
- n = use minor number n
- You can specify up to 64 cameras this way.
- For example:
- video_nr=-1,2,-1 would assign minor number 2 to the second
- recognized camera and use auto for the first one and for every
- other camera.
-Default: -1
--------------------------------------------------------------------------------
-Name: force_munmap
-Type: bool array (min = 0, max = 64)
-Syntax: <0|1[,...]>
-Description: Force the application to unmap previously mapped buffer memory
- before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not
- all the applications support this feature. This parameter is
- specific for each detected camera.
- 0 = do not force memory unmapping
- 1 = force memory unmapping (save memory)
-Default: 0
--------------------------------------------------------------------------------
-Name: frame_timeout
-Type: uint array (min = 0, max = 64)
-Syntax: <0|n[,...]>
-Description: Timeout for a video frame in seconds before returning an I/O
- error; 0 for infinity. This parameter is specific for each
- detected camera and can be changed at runtime thanks to the
- /sys filesystem interface.
-Default: 2
--------------------------------------------------------------------------------
-Name: debug
-Type: ushort
-Syntax: <n>
-Description: Debugging information level, from 0 to 3:
- 0 = none (use carefully)
- 1 = critical errors
- 2 = significant information
- 3 = more verbose messages
- Level 3 is useful for testing only. It also shows some more
- information about the hardware being detected.
- This parameter can be changed at runtime thanks to the /sys
- filesystem interface.
-Default: 2
--------------------------------------------------------------------------------
-
-
-8. Optional device control through "sysfs" [1]
-==========================================
-If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
-it is possible to read and write both the SN9C1xx and the image sensor
-registers by using the "sysfs" filesystem interface.
-
-Every time a supported device is recognized, a write-only file named "green" is
-created in the /sys/class/video4linux/videoX directory. You can set the green
-channel's gain by writing the desired value to it. The value may range from 0
-to 15 for the SN9C101 or SN9C102 bridges, from 0 to 127 for the SN9C103,
-SN9C105 and SN9C120 bridges.
-Similarly, only for the SN9C103, SN9C105 and SN9C120 controllers, blue and red
-gain control files are available in the same directory, for which accepted
-values may range from 0 to 127.
-
-There are other four entries in the directory above for each registered camera:
-"reg", "val", "i2c_reg" and "i2c_val". The first two files control the
-SN9C1xx bridge, while the other two control the sensor chip. "reg" and
-"i2c_reg" hold the values of the current register index where the following
-reading/writing operations are addressed at through "val" and "i2c_val". Their
-use is not intended for end-users. Note that "i2c_reg" and "i2c_val" will not
-be created if the sensor does not actually support the standard I2C protocol or
-its registers are not 8-bit long. Also, remember that you must be logged in as
-root before writing to them.
-
-As an example, suppose we were to want to read the value contained in the
-register number 1 of the sensor register table - which is usually the product
-identifier - of the camera registered as "/dev/video0":
-
- [root@localhost #] cd /sys/class/video4linux/video0
- [root@localhost #] echo 1 > i2c_reg
- [root@localhost #] cat i2c_val
-
-Note that "cat" will fail if sensor registers cannot be read.
-
-Now let's set the green gain's register of the SN9C101 or SN9C102 chips to 2:
-
- [root@localhost #] echo 0x11 > reg
- [root@localhost #] echo 2 > val
-
-Note that the SN9C1xx always returns 0 when some of its registers are read.
-To avoid race conditions, all the I/O accesses to the above files are
-serialized.
-The sysfs interface also provides the "frame_header" entry, which exports the
-frame header of the most recent requested and captured video frame. The header
-is always 18-bytes long and is appended to every video frame by the SN9C1xx
-controllers. As an example, this additional information can be used by the user
-application for implementing auto-exposure features via software.
-
-The following table describes the frame header exported by the SN9C101 and
-SN9C102:

-The list above does not imply that all those devices work with this driver: up
-until now only the ones that assemble the following pairs of SN9C1xx bridges
-and image sensors are supported; kernel messages will always tell you whether
-this is the case (see "Module loading" paragraph):
-
-Image sensor / SN9C1xx bridge | SN9C10[12] SN9C103 SN9C105 SN9C120

-
-"Yes" means that the pair is supported by the driver, while "No" means that the
-pair does not exist or is not supported by the driver.
-
-Only some of the available control settings of each image sensor are supported
-through the V4L2 interface.
-
-Donations of new models for further testing and support would be much
-appreciated. Non-available hardware will not be supported by the author of this
-driver.
-
-
-10. Notes for V4L2 application developers
-=========================================
-This driver follows the V4L2 API specifications. In particular, it enforces two
-rules:
-
-- exactly one I/O method, either "mmap" or "read", is associated with each
-file descriptor. Once it is selected, the application must close and reopen the
-device to switch to the other I/O method;
-
-- although it is not mandatory, previously mapped buffer memory should always
-be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's.
-The same number of buffers as before will be allocated again to match the size
-of the new video frames, so you have to map the buffers again before any I/O
-attempts on them.
-
-Consistently with the hardware limits, this driver also supports image
-downscaling with arbitrary scaling factors from 1, 2 and 4 in both directions.
-However, the V4L2 API specifications don't correctly define how the scaling
-factor can be chosen arbitrarily by the "negotiation" of the "source" and
-"target" rectangles. To work around this flaw, we have added the convention
-that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the
-scaling factor is restored to 1.
-
-This driver supports two different video formats: the first one is the "8-bit
-Sequential Bayer" format and can be used to obtain uncompressed video data
-from the device through the current I/O method, while the second one provides
-either "raw" compressed video data (without frame headers not related to the
-compressed data) or standard JPEG (with frame headers). The compression quality
-may vary from 0 to 1 and can be selected or queried thanks to the
-VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP V4L2 ioctl's. For maximum flexibility,
-both the default active video format and the default compression quality
-depend on how the image sensor being used is initialized.
-
-
-11. Video frame formats [1]
-=======================
-The SN9C1xx PC Camera Controllers can send images in two possible video
-formats over the USB: either native "Sequential RGB Bayer" or compressed.
-The compression is used to achieve high frame rates. With regard to the
-SN9C101, SN9C102 and SN9C103, the compression is based on the Huffman encoding
-algorithm described below, while with regard to the SN9C105 and SN9C120 the
-compression is based on the JPEG standard.
-The current video format may be selected or queried from the user application
-by calling the VIDIOC_S_FMT or VIDIOC_G_FMT ioctl's, as described in the V4L2
-API specifications.
-
-The name "Sequential Bayer" indicates the organization of the red, green and
-blue pixels in one video frame. Each pixel is associated with a 8-bit long
-value and is disposed in memory according to the pattern shown below:
-
-B[0] G[1] B[2] G[3] ... B[m-2] G[m-1]
-G[m] R[m+1] G[m+2] R[m+2] ... G[2m-2] R[2m-1]
-...
-... B[(n-1)(m-2)] G[(n-1)(m-1)]
-... G[n(m-2)] R[n(m-1)]
-
-The above matrix also represents the sequential or progressive read-out mode of
-the (n, m) Bayer color filter array used in many CCD or CMOS image sensors.
-
-The Huffman compressed video frame consists of a bitstream that encodes for
-every R, G, or B pixel the difference between the value of the pixel itself and
-some reference pixel value. Pixels are organised in the Bayer pattern and the
-Bayer sub-pixels are tracked individually and alternatingly. For example, in
-the first line values for the B and G1 pixels are alternatingly encoded, while
-in the second line values for the G2 and R pixels are alternatingly encoded.
-
-The pixel reference value is calculated as follows:
-- the 4 top left pixels are encoded in raw uncompressed 8-bit format;
-- the value in the top two rows is the value of the pixel left of the current
- pixel;
-- the value in the left column is the value of the pixel above the current
- pixel;
-- for all other pixels, the reference value is the average of the value of the
- pixel on the left and the value of the pixel above the current pixel;
-- there is one code in the bitstream that specifies the value of a pixel
- directly (in 4-bit resolution);
-- pixel values need to be clamped inside the range [0..255] for proper
- decoding.
-
-The algorithm purely describes the conversion from compressed Bayer code used
-in the SN9C101, SN9C102 and SN9C103 chips to uncompressed Bayer. Additional
-steps are required to convert this to a color image (i.e. a color interpolation
-algorithm).
-
-The following Huffman codes have been found:
-0: +0 (relative to reference pixel value)
-100: +4
-101: -4?
-1110xxxx: set absolute value to xxxx.0000
-1101: +11
-1111: -11
-11001: +20
-110000: -20
-110001: ??? - these codes are apparently not used
-
-[1] The Huffman compression algorithm has been reverse-engineered and
- documented by Bertrik Sikken.

- OVERVIEW.
- This is a small interface that allows you to add support for any CCD/CMOS
- image sensors connected to the SN9C1XX bridges. The entire API is documented
- below. In the most general case, to support a sensor there are three steps
- you have to follow:
- 1) define the main "sn9c102_sensor" structure by setting the basic fields;
- 2) write a probing function to be called by the core module when the USB
- camera is recognized, then add both the USB ids and the name of that
- function to the two corresponding tables in sn9c102_devtable.h;
- 3) implement the methods that you want/need (and fill the rest of the main
- structure accordingly).
- "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
- NOT need to touch the source code of the core module for the things to work
- properly, unless you find bugs or flaws in it. Finally, do not forget to
- read the V4L2 API for completeness.

- Think the image sensor as a grid of R,G,B monochromatic pixels

- chip can be programmed to capture/transmit a subsection of that
- array of pixels: we will call this subsection "active window".
- It is not always true that the largest achievable active window can
- cover the whole array of pixels. The V4L2 API defines another
- area called "source rectangle", which, in turn, is a subrectangle of
- the active window. The SN9C1XX chip is always programmed to read the
- source rectangle.
- The bounds of both the active window and the source rectangle are
- specified in the cropcap substructures 'bounds' and 'defrect'.
- By default, the source rectangle should cover the largest possible
- area. Again, it is not always true that the largest source rectangle
- can cover the entire active window, although it is a rare case for
- the hardware we have. The bounds of the source rectangle _must_ be
- multiple of 16 and must use the same coordinate system as indicated
- before; their centers shall align initially.
- If necessary, the sensor chip must be initialized during init() to
- set the bounds of the active sensor window; however, by default, it
- usually covers the largest achievable area (maxwidth x maxheight)
- of pixels, so no particular initialization is needed, if you have
- defined the correct default bounds in the structures.
- See the V4L2 API for further details.
- NOTE: once you have defined the bounds of the active window
- (struct cropcap.bounds) you must not change them.anymore.
