+How to get the bt8xx cards working
+==================================

+1) General information
+======================
-Please pay close attention to the warning about the bttv module
-options below for the DST card.
+This class of cards has a bt878a as the PCI interface, and require the bttv driver

-=======================
-
-These drivers require the bttv driver to provide the means to access
-the i2c bus and the gpio pins of the bt8xx chipset.
-
-Because of this, you need to enable

- => "Video For Linux" => "BT848 Video For Linux"
-
-Furthermore you need to enable
-"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"

+b.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
+ => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
2) Loading Modules
==================
-In general you need to load the bttv driver, which will handle the gpio and
-i2c communication for us, plus the common dvb-bt8xx device driver.
-The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110), TwinHan (dst),
-FusionHDTV DVB-T Lite (mt352) and FusionHDTV5 Lite (lgdt330x) are loaded
-automatically by the dvb-bt8xx device driver.
-
-3a) Nebula / Pinnacle PCTV / FusionHDTV Lite
----------------------------------------------
-
- $ modprobe bttv (normally bttv is being loaded automatically by kmod)
- $ modprobe dvb-bt8xx
-
-(or just place dvb-bt8xx in /etc/modules for automatic loading)
-
-
-3b) TwinHan and Clones
---------------------------
+In default cases bttv is loaded automatically.
+To load the backend either place dvb-bt8xx in etc/modules, or apply manually:
- $ modprobe bttv card=0x71
- $ modprobe dvb-bt8xx
- $ modprobe dst
+ $ modprobe dvb-bt8xx
-The value 0x71 will override the PCI type detection for dvb-bt8xx,
-which is necessary for TwinHan cards. Omission of this parameter might result
-in a system lockup.
+All frontends will be loaded automatically.
+People running udev please see Documentation/dvb/udev.txt.
-If you're having an older card (blue color PCB) and card=0x71 locks up
-your machine, try using 0x68, too. If that does not work, ask on the
-mailing list.
+In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
-The DST module takes a couple of useful parameters.
+2a) Running TwinHan and Clones
+------------------------------
-verbose takes values 0 to 4. These values control the verbosity level,
-and can be used to debug also.
+ $ modprobe bttv card=113
+ $ modprobe dvb-bt8xx
+ $ modprobe dst
-verbose=0 means complete disabling of messages
- 1 only error messages are displayed
- 2 notifications are also displayed
- 3 informational messages are also displayed
- 4 debug setting
+Useful parameters for verbosity level and debugging the dst module:
-dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
-0x20 means it has a Conditional Access slot.
+verbose=0: messages are disabled
+ 1: only error messages are displayed
+ 2: notifications are displayed
+ 3: other useful messages are displayed
+ 4: debug setting
+dst_addons=0: card is a free to air (FTA) card only
+ 0x20: card has a conditional access slot for scrambled channels
-The autodetected values are determined by the cards 'response string'
-which you can see in your logs e.g.
+The autodetected values are determined by the cards' "response string".
+In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
+For bug reports please send in a complete log with verbose=4 activated.
+Please also see Documentation/dvb/ci.txt.
-dst_get_device_id: Recognise [DSTMCI]
-
-If you need to sent in bug reports on the dst, please do send in a complete
-log with the verbose=4 module parameter. For general usage, the default setting
-of verbose=1 is ideal.
-
-
-4) Multiple cards
+2b) Running multiple cards
--------------------------
-If you happen to be running multiple cards, it would be advisable to load
-the bttv module with the card id. This would help to solve any module loading
-problems that you might face.
-
-For example, if you have a Twinhan and Clones card along with a FusionHDTV5 Lite
+Examples of card ID's:
- $ modprobe bttv card=0x71 card=0x87
-
-Here the order of the card id is important and should be the same as that of the
-physical order of the cards. Here card=0x71 represents the Twinhan and clones
-and card=0x87 represents Fusion HDTV5 Lite. These arguments can also be
-specified in decimal, rather than hex:
+Pinnacle PCTV Sat: 94
+Nebula Electronics Digi TV: 104
+pcHDTV HD-2000 TV: 112
+Twinhan DST and clones: 113
+Avermedia AverTV DVB-T 771: 123
+Avermedia AverTV DVB-T 761: 124
+DViCO FusionHDTV DVB-T Lite: 128
+DViCO FusionHDTV 5 Lite: 135
+Notice: The order of the card ID should be uprising:
+Example:
$ modprobe bttv card=113 card=135
+ $ modprobe dvb-bt8xx
-Some examples of card-id's
-
-Pinnacle Sat 0x5e (94)
-Nebula Digi TV 0x68 (104)
-PC HDTV 0x70 (112)
-Twinhan 0x71 (113)
-FusionHDTV DVB-T Lite 0x80 (128)
-FusionHDTV5 Lite 0x87 (135)
-
-For a full list of card-id's, see the V4L Documentation within the kernel
-source: linux/Documentation/video4linux/CARDLIST.bttv
-
-If you have problems with this please do ask on the mailing list.
+For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.

Additional Configurations
=========================
Configuring the Driver on Different Distributions
-------------------------------------------------
- Configuring a network driver to load properly when the system is started is
- distribution dependent. Typically, the configuration process involves adding
- an alias line to /etc/modules.conf as well as editing other system startup
- scripts and/or configuration files. Many popular Linux distributions ship
- with tools to make these changes for you. To learn the proper way to
- configure a network device for your system, refer to your distribution
- documentation. If during this process you are asked for the driver or module
- name, the name for the Linux Base Driver for the Intel PRO/100 Family of

+ one system on two IP networks in the same Ethernet broadcast domain
+ (non-partitioned switch) behave as expected. All Ethernet interfaces
+ will respond to IP traffic for any IP address assigned to the system.
+ This results in unbalanced receive traffic.
+
+ If you have multiple interfaces in a server, either turn on ARP
+ filtering by
+
+ (1) entering: echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+ (this only works if your kernel's version is higher than 2.4.5), or
+
+ (2) installing the interfaces in separate broadcast domains (either
+ in different switches or in a switch partitioned to VLANs).

+---------------------
+(not supported on Intel 82542, 82543 or 82544-based adapters)
+Valid Range: 100-100000 (0=off, 1=dynamic)
Default Value: 8000
- This value represents the maximum number of interrupts per second the
- controller generates. InterruptThrottleRate is another setting used in
- interrupt moderation. Dynamic mode uses a heuristic algorithm to adjust
- InterruptThrottleRate based on the current traffic load.
-Un-supported Adapters: InterruptThrottleRate is NOT supported by 82542, 82543
- or 82544-based adapters.
-
- NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
- RxAbsIntDelay parameters. In other words, minimizing the receive
- and/or transmit absolute delays does not force the controller to
- generate more interrupts than what the Interrupt Throttle Rate
- allows.
- CAUTION: If you are using the Intel PRO/1000 CT Network Connection
- (controller 82547), setting InterruptThrottleRate to a value
- greater than 75,000, may hang (stop transmitting) adapters under
- certain network conditions. If this occurs a NETDEV WATCHDOG
- message is logged in the system event log. In addition, the
- controller is automatically reset, restoring the network
- connection. To eliminate the potential for the hang, ensure
- that InterruptThrottleRate is set no greater than 75,000 and is
- not set to 0.
- NOTE: When e1000 is loaded with default settings and multiple adapters are
- in use simultaneously, the CPU utilization may increase non-linearly.
- In order to limit the CPU utilization without impacting the overall
- throughput, we recommend that you load the driver as follows:
-
- insmod e1000.o InterruptThrottleRate=3000,3000,3000
-
- This sets the InterruptThrottleRate to 3000 interrupts/sec for the
- first, second, and third instances of the driver. The range of 2000 to
- 3000 interrupts per second works on a majority of systems and is a
- good starting point, but the optimal value will be platform-specific.
- If CPU utilization is not a concern, use RX_POLLING (NAPI) and default
- driver settings.

- This value is the number of receive descriptors allocated by the driver.
- Increasing this value allows the driver to buffer more incoming packets.
- Each descriptor is 16 bytes. A receive buffer is allocated for each

RxIntDelay
-Valid Range: 0-65535 (0=off)
+----------
+Valid Range: 0-65535 (0=off)
Default Value: 0
- This value delays the generation of receive interrupts in units of 1.024
- microseconds. Receive interrupt reduction can improve CPU efficiency if
- properly tuned for specific network traffic. Increasing this value adds
- extra latency to frame reception and can end up decreasing the throughput
- of TCP traffic. If the system is reporting dropped receives, this value
- may be set too high, causing the driver to run out of available receive
- descriptors.
-
- CAUTION: When setting RxIntDelay to a value other than 0, adapters may

+ modprobe e1000 AutoNeg=0x020 (Restricts autonegotiation to 1000 Full)
+ modprobe e1000 AutoNeg=32 (Same as above)
-Note that setting AutoNeg does not guarantee that the board will link at the

-highest possible speed/duplex of the link partner IF the link partner is also
-set to auto-negotiate. If the link partner is forced speed/duplex, the
-adapter MUST be forced to the same speed/duplex.

+
+ Jumbo frames on Foundry BigIron 8000 switch
+ -------------------------------------------
+ There is a known issue using Jumbo frames when connected to a Foundry
+ BigIron 8000 switch. This is a 3rd party limitation. If you experience
+ loss of packets, lower the MTU size.
+
+ Multiple Interfaces on Same Ethernet Broadcast Network
+ ------------------------------------------------------
+
+ Due to the default ARP behavior on Linux, it is not possible to have
+ one system on two IP networks in the same Ethernet broadcast domain
+ (non-partitioned switch) behave as expected. All Ethernet interfaces
+ will respond to IP traffic for any IP address assigned to the system.
+ This results in unbalanced receive traffic.
+
+ If you have multiple interfaces in a server, either turn on ARP
+ filtering by entering:
+
+ echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+ (this only works if your kernel's version is higher than 2.4.5),
+
+ NOTE: This setting is not saved across reboots. The configuration
+ change can be made permanent by adding the line:
+ net.ipv4.conf.all.arp_filter = 1
+ to the file /etc/sysctl.conf
+
+ or,
+
+ install the interfaces in separate broadcast domains (either in
+ different switches or in a switch partitioned to VLANs).
+
+ 82541/82547 can't link or are slow to link with some link partners
+ -----------------------------------------------------------------
+
+ There is a known compatibility issue with 82541/82547 and some

+ be incompatible with 82541/82547:
+
+ Planex FXG-08TE
+ I-O Data ETG-SH8
+
+ To workaround this issue, the driver can be compiled with an override

+
+
+4. Overview and features
+========================
+This driver supports the video interface of the devices mounting the ZC0301
+Image Processor and Control Chip.
+
+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 ZC0301 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;
+- video format is standard JPEG;
+- 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;
+
+
+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
+
+ # 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 ZC0301 controller also provides 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_ZC0301=m
+
+
+6. Module loading
+=================
+To use the driver, it is necessary to load the "zc0301" module into memory
+after every other module required: "videodev", "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 zc0301
+
+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 informations
+ 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 informations
+ about the hardware being detected. This module parameter can be
+ changed at runtime thanks to the /sys filesystem interface.
+Default: 2

+
+
+8. 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 ZC0301 Image Processor and Control Chips:
+

+9. 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.
+
+
+10. Contact information
+=======================
+The author may be contacted by e-mail at <luca.risolia@studio.unibo.it>.
+
+GPG/PGP encrypted e-mail's are accepted. The GPG key ID of the author is
+'FCE635A4'; the public 1024-bit key should be available at any keyserver;

+1. 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 separted 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.
+
+2. Making and installing the stv672 driver modules:
+
+ Requirements:
+ -------------
+ This should work with 2.4 (2.4.23 and later) and 2.6 kernels, but has
+only been tested on 2.6. Video4Linux must be either compiled into the kernel or
+available as a module. Video4Linux2 is automatically detected and made
+available at compile time.
+
+ Compiling:
+ ----------
+ As root, do a make install. This will compile and install the modules
+into the media/video directory in the module tree. For 2.4 kernels, use
+Makefile_2.4 (aka do make -f Makefile_2.4 install).
+
+ Setup:
+ ------
+ Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This
+may be done automatically by your distribution.
+
+3. Driver options
+
+ Option Description
+ ------ -----------
+ video_nr video device to register (0=/dev/video0, etc)
+ range -1 to 64. default is -1 (first available)
+ If you have more than 1 camera, this MUST be -1.
+ buffer_size Size for each frame buffer in bytes (default 68k)
+ num_buffers Number of frame buffers (1-32, default 3)
+ alternate USB Alternate (2-7, default 7)
+ flicker_freq Frequency for flicker reduction(50 or 60, default 60)
+ flicker_mode 0 to disable, or 1 to enable flicker reduction.
+ (default 0). This is only effective if the camera
+ uses a stv0672 coprocessor.
+
+ Setting the options:
+ --------------------
+ If you are using modules, edit /etc/modules.conf and add an options
+line like this:
+ options cpia2 num_buffers=3 buffer_size=65535
+
+ If the driver is compiled into the kernel, at boot time specify them
+like this:
+ cpia2.num_buffers=3 cpia2.buffer_size=65535
+
+ What buffer size should I use?
+ ------------------------------
+ The maximum image size depends on the alternate you choose, and the
+frame rate achieved by the camera. 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.
+
+ Image size(bytes)
+ 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
+
+ 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.
+
+4. 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.
+
+5. Notes to developers:
+
+ - This is a driver version stripped of the 2.4 back compatibility
+ and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support.
+
+6. Thanks:
+
+ - 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.

+ Programmer's View of Cpia2
+
+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. \ No newline at end of file
