-
-4. Overview and features
-========================
-This driver supports the video interface of the devices mounting the ET61X151
-or ET61X251 PC Camera Controllers.
-
-It's worth to note that Etoms Electronics has never collaborated with the
-author during the development of this project; despite several requests,
-Etoms Electronics also refused to release enough detailed specifications of
-the video compression engine.
-
-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 ET61X[12]51 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 any window resolutions and optional panning within the maximum
- pixel area of image sensor;
-- image downscaling with arbitrary scaling factors from 1 and 2 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"
- paragraph);
-- full support for the capabilities of every possible image sensors that can
- be connected to the ET61X[12]51 bridges, including, for instance, red, green,
- blue and global gain adjustments and exposure control (see "Supported
- devices" paragraph for details);
-- use of default color settings for sunlight conditions;
-- dynamic I/O interface for both ET61X[12]51 and image sensor control (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
-
-And finally:
-
- # USB Multimedia devices
- #
- CONFIG_USB_ET61X251=m
-
-
-6. Module loading
-=================
-To use the driver, it is necessary to load the "et61x251" 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 et61x251
-
-At this point the devices should be recognized. You can invoke "dmesg" to
-analyze kernel messages and verify that the loading process has gone well:
-
- [user@localhost home]$ dmesg
-
-
-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
- registered 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: <n[,...]>
-Description: Timeout for a video frame in seconds. This parameter is
- specific for each detected camera. This parameter 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, when only one device
- is used at the same time. It also shows some more information
- about the hardware being detected. This module parameter can be
- changed at runtime thanks to the /sys filesystem interface.
-Default: 2
--------------------------------------------------------------------------------
-
-
-8. Optional device control through "sysfs"
-==========================================
-If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
-it is possible to read and write both the ET61X[12]51 and the image sensor
-registers by using the "sysfs" filesystem interface.
-
-There are four files in the /sys/class/video4linux/videoX directory for each
-registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files
-control the ET61X[12]51 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, unless you know what you
-are doing. 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 if the sensor registers cannot be read, "cat" will fail.
-To avoid race conditions, all the I/O accesses to the files are serialized.
-
-
-9. Supported devices
-====================
-None of the names of the companies as well as their products will be mentioned
-here. They have never collaborated with the author, so no advertising.
-
-From the point of view of a driver, what unambiguously identify a device are
-its vendor and product USB identifiers. Below is a list of known identifiers of
-devices mounting the ET61X[12]51 PC camera controllers:

-
-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 and 2 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
-"raw" compressed video data (without frame headers not related to the
-compressed data). The current 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.

-README for Linux device driver for the IBM "C-It" USB video camera
-
-INTRODUCTION:
-
-This driver does not use all features known to exist in
-the IBM camera. However most of needed features work well.
-
-This driver was developed using logs of observed USB traffic
-which was produced by standard Windows driver (c-it98.sys).
-I did not have data sheets from Xirlink.
-
-Video formats:
- 128x96 [model 1]
- 176x144
- 320x240 [model 2]
- 352x240 [model 2]
- 352x288
-Frame rate: 3 - 30 frames per second (FPS)
-External interface: USB
-Internal interface: Video For Linux (V4L)
-Supported controls:
-- by V4L: Contrast, Brightness, Color, Hue
-- by driver options: frame rate, lighting conditions, video format,
- default picture settings, sharpness.
-
-SUPPORTED CAMERAS:
-
-Xirlink "C-It" camera, also known as "IBM PC Camera".
-The device uses proprietary ASIC (and compression method);
-it is manufactured by Xirlink. See http://xirlinkwebcam.sourceforge.net,
-http://www.ibmpccamera.com, or http://www.c-itnow.com/ for details and pictures.
-
-This very chipset ("X Chip", as marked at the factory)
-is used in several other cameras, and they are supported
-as well:
-
-- IBM NetCamera
-- Veo Stingray
-
-The Linux driver was developed with camera with following
-model number (or FCC ID): KSX-XVP510. This camera has three
-interfaces, each with one endpoint (control, iso, iso). This
-type of cameras is referred to as "model 1". These cameras are
-no longer manufactured.
-
-Xirlink now manufactures new cameras which are somewhat different.
-In particular, following models [FCC ID] belong to that category:
-
-XVP300 [KSX-X9903]
-XVP600 [KSX-X9902]
-XVP610 [KSX-X9902]
-
-(see http://www.xirlink.com/ibmpccamera/ for updates, they refer
-to these new cameras by Windows driver dated 12-27-99, v3005 BETA)
-These cameras have two interfaces, one endpoint in each (iso, bulk).
-Such type of cameras is referred to as "model 2". They are supported
-(with exception of 352x288 native mode).
-
-Some IBM NetCameras (Model 4) are made to generate only compressed
-video streams. This is great for performance, but unfortunately
-nobody knows how to decompress the stream :-( Therefore, these
-cameras are *unsupported* and if you try to use one of those, all
-you get is random colored horizontal streaks, not the image!
-If you have one of those cameras, you probably should return it
-to the store and get something that is supported.
-
-Tell me more about all that "model" business
---------------------------------------------
-
-I just invented model numbers to uniquely identify flavors of the
-hardware/firmware that were sold. It was very confusing to use
-brand names or some other internal numbering schemes. So I found
-by experimentation that all Xirlink chipsets fall into four big
-classes, and I called them "models". Each model is programmed in
-its own way, and each model sends back the video in its own way.
-
-Quirks of Model 2 cameras:
--------------------------
-
-Model 2 does not have hardware contrast control. Corresponding V4L
-control is implemented in software, which is not very nice to your
-CPU, but at least it works.
-
-This driver provides 352x288 mode by switching the camera into
-quasi-352x288 RGB mode (800 Kbits per frame) essentially limiting
-this mode to 10 frames per second or less, in ideal conditions on
-the bus (USB is shared, after all). The frame rate
-has to be programmed very conservatively. Additional concern is that
-frame rate depends on brightness setting; therefore the picture can
-be good at one brightness and broken at another! I did not want to fix
-the frame rate at slowest setting, but I had to move it pretty much down
-the scale (so that framerate option barely matters). I also noticed that
-camera after first powering up produces frames slightly faster than during
-consecutive uses. All this means that if you use 352x288 (which is
-default), be warned - you may encounter broken picture on first connect;
-try to adjust brightness - brighter image is slower, so USB will be able
-to send all data. However if you regularly use Model 2 cameras you may
-prefer 176x144 which makes perfectly good I420, with no scaling and
-lesser demands on USB (300 Kbits per second, or 26 frames per second).
-
-Another strange effect of 352x288 mode is the fine vertical grid visible
-on some colored surfaces. I am sure it is caused by me not understanding
-what the camera is trying to say. Blame trade secrets for that.
-
-The camera that I had also has a hardware quirk: if disconnected,
-it needs few minutes to "relax" before it can be plugged in again
-(poorly designed USB processor reset circuit?)
-
-[Veo Stingray with Product ID 0x800C is also Model 2, but I haven't
-observed this particular flaw in it.]
-
-Model 2 camera can be programmed for very high sensitivity (even starlight
-may be enough), this makes it convenient for tinkering with. The driver
-code has enough comments to help a programmer to tweak the camera
-as s/he feels necessary.
-
-WHAT YOU NEED:
-
-- A supported IBM PC (C-it) camera (model 1 or 2)
-
-- A Linux box with USB support (2.3/2.4; 2.2 w/backport may work)
-
-- A Video4Linux compatible frame grabber program such as xawtv.

-HOW TO COMPILE THE DRIVER:
-
-You need to compile the driver only if you are a developer
-or if you want to make changes to the code. Most distributions
-precompile all modules, so you can go directly to the next
-section "HOW TO USE THE DRIVER".
-
-The ibmcam driver uses usbvideo helper library (module),
-so if you are studying the ibmcam code you will be led there.
-
-The driver itself consists of only one file in usb/ directory:
-ibmcam.c. This file is included into the Linux kernel build
-process if you configure the kernel for CONFIG_USB_IBMCAM.
-Run "make xconfig" and in USB section you will find the IBM
-camera driver. Select it, save the configuration and recompile.
-
-HOW TO USE THE DRIVER:
-
-I recommend to compile driver as a module. This gives you an
-easier access to its configuration. The camera has many more
-settings than V4L can operate, so some settings are done using
-module options.
-
-To begin with, on most modern Linux distributions the driver
-will be automatically loaded whenever you plug the supported
-camera in. Therefore, you don't need to do anything. However
-if you want to experiment with some module parameters then
-you can load and unload the driver manually, with camera
-plugged in or unplugged.
-
-Typically module is installed with command 'modprobe', like this:
-
-# modprobe ibmcam framerate=1
-
-Alternatively you can use 'insmod' in similar fashion:
-
-# insmod /lib/modules/2.x.y/usb/ibmcam.o framerate=1
-
-Module can be inserted with camera connected or disconnected.
-
-The driver can have options, though some defaults are provided.
-
-Driver options: (* indicates that option is model-dependent)

-
-debug You don't need this option unless you are a developer.
- If you are a developer then you will see in the code
- what values do what. 0=off.
-
-flags This is a bit mask, and you can combine any number of
- bits to produce what you want. Usually you don't want
- any of extra features this option provides:
-
- FLAGS_RETRY_VIDIOCSYNC 1 This bit allows to retry failed
- VIDIOCSYNC ioctls without failing.
- Will work with xawtv, will not
- with xrealproducer. Default is
- not set.
- FLAGS_MONOCHROME 2 Activates monochrome (b/w) mode.
- FLAGS_DISPLAY_HINTS 4 Shows colored pixels which have
- magic meaning to developers.
- FLAGS_OVERLAY_STATS 8 Shows tiny numbers on screen,
- useful only for debugging.
- FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers.
- FLAGS_SEPARATE_FRAMES 32 Shows each frame separately, as
- it was received from the camera.
- Default (not set) is to mix the
- preceding frame in to compensate
- for occasional loss of Isoc data
- on high frame rates.
- FLAGS_CLEAN_FRAMES 64 Forces "cleanup" of each frame
- prior to use; relevant only if
- FLAGS_SEPARATE_FRAMES is set.
- Default is not to clean frames,
- this is a little faster but may
- produce flicker if frame rate is
- too high and Isoc data gets lost.
- FLAGS_NO_DECODING 128 This flag turns the video stream
- decoder off, and dumps the raw
- Isoc data from the camera into
- the reading process. Useful to
- developers, but not to users.
-
-framerate This setting controls frame rate of the camera. This is
- an approximate setting (in terms of "worst" ... "best")
- because camera changes frame rate depending on amount
- of light available. Setting 0 is slowest, 6 is fastest.
- Beware - fast settings are very demanding and may not
- work well with all video sizes. Be conservative.
-
-hue_correction This highly optional setting allows to adjust the
- hue of the image in a way slightly different from
- what usual "hue" control does. Both controls affect
- YUV colorspace: regular "hue" control adjusts only
- U component, and this "hue_correction" option similarly
- adjusts only V component. However usually it is enough
- to tweak only U or V to compensate for colored light or
- color temperature; this option simply allows more
- complicated correction when and if it is necessary.
-
-init_brightness These settings specify _initial_ values which will be
-init_contrast used to set up the camera. If your V4L application has
-init_color its own controls to adjust the picture then these
-init_hue controls will be used too. These options allow you to
- preconfigure the camera when it gets connected, before
- any V4L application connects to it. Good for webcams.
-
-init_model2_rg These initial settings alter color balance of the
-init_model2_rg2 camera on hardware level. All four settings may be used
-init_model2_sat to tune the camera to specific lighting conditions. These
-init_model2_yb settings only apply to Model 2 cameras.
-
-lighting This option selects one of three hardware-defined
- photosensitivity settings of the camera. 0=bright light,
- 1=Medium (default), 2=Low light. This setting affects
- frame rate: the dimmer the lighting the lower the frame
- rate (because longer exposition time is needed). The
- Model 2 cameras allow values more than 2 for this option,
- thus enabling extremely high sensitivity at cost of frame
- rate, color saturation and imaging sensor noise.
-
-sharpness This option controls smoothing (noise reduction)
- made by camera. Setting 0 is most smooth, setting 6
- is most sharp. Be aware that CMOS sensor used in the
- camera is pretty noisy, so if you choose 6 you will
- be greeted with "snowy" image. Default is 4. Model 2
- cameras do not support this feature.
-
-size This setting chooses one of several image sizes that are
- supported by this driver. Cameras may support more, but
- it's difficult to reverse-engineer all formats.
- Following video sizes are supported:
-
- size=0 128x96 (Model 1 only)
- size=1 160x120
- size=2 176x144
- size=3 320x240 (Model 2 only)
- size=4 352x240 (Model 2 only)
- size=5 352x288
- size=6 640x480 (Model 3 only)
-
- The 352x288 is the native size of the Model 1 sensor
- array, so it's the best resolution the camera can
- yield. The best resolution of Model 2 is 176x144, and
- larger images are produced by stretching the bitmap.
- Model 3 has sensor with 640x480 grid, and it works too,
- but the frame rate will be exceptionally low (1-2 FPS);
- it may be still OK for some applications, like security.
- Choose the image size you need. The smaller image can
- support faster frame rate. Default is 352x288.

-WHAT NEEDS TO BE DONE:
-
-- The button on the camera is not used. I don't know how to get to it.
- I know now how to read button on Model 2, but what to do with it?
-
-- Camera reports its status back to the driver; however I don't know
- what returned data means. If camera fails at some initialization
- stage then something should be done, and I don't do that because
- I don't even know that some command failed. This is mostly Model 1
- concern because Model 2 uses different commands which do not return
- status (and seem to complete successfully every time).
-
-- Some flavors of Model 4 NetCameras produce only compressed video
- streams, and I don't know how to decode them.

-This document describes the ALi m5602 bridge connected
-to the following supported sensors:
-OmniVision OV9650,
-Samsung s5k83a,
-Samsung s5k4aa,
-Micron mt9m111,
-Pixel plus PO1030
-
-This driver mimics the windows drivers, which have a braindead implementation sending bayer-encoded frames at VGA resolution.
-In a perfect world we should be able to reprogram the m5602 and the connected sensor in hardware instead, supporting a range of resolutions and pixelformats
-
-Anyway, have fun and please report any bugs to m560x-driver-devel@lists.sourceforg
