- - let s2250-board use i2c subdevs as well instead of hardcoding
- support for the i2c devices.
- - when the driver is moved out of staging, support for saa7134-go7007
- should be added to the saa7134 driver. The patch for that is

-
- 0. OVERVIEW AND LICENSING/DISCLAIMER
-
-
-This driver kit contains Linux drivers for the WIS GO7007SB multi-format
-video encoder. Only kernel version 2.6.x is supported. The video stream
-is available through the Video4Linux2 API and the audio stream is available
-through the ALSA API (or the OSS emulation layer of the ALSA system).
-
-The files in kernel/ and hotplug/ are licensed under the GNU General Public
-License Version 2 from the Free Software Foundation. A copy of the license
-is included in the file COPYING.
-
-The example applications in apps/ and C header files in include/ are
-licensed under a permissive license included in the source files which
-allows copying, modification and redistribution for any purpose without
-attribution.
-
-The firmware files included in the firmware/ directory may be freely
-redistributed only in conjunction with this document; but modification,
-tampering and reverse engineering are prohibited.
-
-MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH
-RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR
-LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION
-WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR
-PURPOSE AND NON-INFRINGEMENT.
-
-
- 1. SYSTEM REQUIREMENTS
-
-
-This driver requires Linux kernel 2.6. Kernel 2.4 is not supported. Using
-kernel 2.6.10 or later is recommended, as earlier kernels are known to have
-unstable USB 2.0 support.
-
-A fully built kernel source tree must be available. Typically this will be
-linked from "/lib/modules/<KERNEL VERSION>/build" for convenience. If this
-link does not exist, an extra parameter will need to be passed to the
-`make` command.
-
-All vendor-built kernels should already be configured properly. However,
-for custom-built kernels, the following options need to be enabled in the
-kernel as built-in or modules:
-
- CONFIG_MODULES - Enable loadable module support
- CONFIG_FW_LOADER - Hotplug firmware loading support
- CONFIG_I2C - I2C support
- CONFIG_VIDEO_DEV - Video For Linux
- CONFIG_SOUND - Sound card support
- CONFIG_SND - Advanced Linux Sound Architecture
- CONFIG_USB - Support for Host-side USB
- CONFIG_USB_EHCI_HCD - EHCI HCD (USB 2.0) support
-
-Additionally, to use the example application, the following options need to
-be enabled in the ALSA section:
-
- CONFIG_SND_MIXER_OSS - OSS Mixer API
- CONFIG_SND_PCM_OSS - OSS PCM (digital audio) API
-
-The hotplug scripts, along with the fxload utility, must also be installed.
-These scripts can be obtained from <http://linux-hotplug.sourceforge.net/>.
-Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using
-fxload and for loading firmware into the driver using the firmware agent.
-
-
- 2. COMPILING AND INSTALLING THE DRIVER
-
-
-Most users should be able to compile the driver by simply running:
-
- $ make
-
-in the top-level directory of the driver kit. First the kernel modules
-will be built, followed by the example applications.
-
-If the build system is unable to locate the kernel source tree for the
-currently-running kernel, or if the module should be built for a kernel
-other than the currently-running kernel, an additional parameter will need
-to be passed to make to specify the appropriate kernel source directory:
-
- $ make KERNELSRC=/usr/src/linux-2.6.10-custom3
-
-Once the compile completes, the driver and firmware files should be
-installed by running:
-
- $ make install
-
-The kernel modules will be placed in "/lib/modules/<KERNEL VERSION>/extra"
-and the firmware files will be placed in the appropriate hotplug firmware
-directory, usually /lib/firmware. In addition, USB maps and scripts will
-be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB
-control chip when the device is connected.
-
-
- 3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only)
-
-
-The PAL model of the Plextor ConvertX TV402U may require additional
-configuration to correctly select the appropriate TV frequency band and
-audio subchannel.
-
-Users with a device other than the Plextor ConvertX TV402U-EU should skip
-this section.
-
-The wide variety of PAL TV systems used in Europe requires that additional
-information about the local TV standards be passed to the driver in order
-to properly tune TV channels. The two necessary parameters are (a) the PAL
-TV band, and (b) the audio subchannel format in use.
-
-In many cases, the appropriate TV band selection is passed to the driver
-from applications. However, in some cases, the application only specifies
-that the driver should use PAL but not the specific information about the
-appropriate TV band. To work around this issue, the correct TV band may be
-specified in the "force_band" parameter to the wis-sony-tuner module:
-
- TV band force_band
- ------- ----------
- PAL B/G B
- PAL I I
- PAL D/K D
- SECAM L L
-
-If the "force_band" parameter is specified, the driver will ignore any TV
-band specified by applications and will always use the band provided in the
-module parameter.
-
-The other parameter that can be specified is the audio subchannel format.
-There are several stereo audio carrier systems in use, including NICAM and
-three varieties of A2. To receive audio broadcast on one of these stereo
-carriers, the "force_mpx_mode" parameter must be specified to the
-wis-sony-tuner module.
-
- TV band Audio subcarrier force_mpx_mode
- ------- ---------------- --------------
- PAL B/G Mono (default) 1
- PAL B/G A2 2
- PAL B/G NICAM 3
- PAL I Mono (default) 4
- PAL I NICAM 5
- PAL D/K Mono (default) 6
- PAL D/K A2 (1) 7
- PAL D/K A2 (2) 8
- PAL D/K A2 (3) 9
- PAL D/K NICAM 10
- SECAM L Mono (default) 11
- SECAM L NICAM 12
-
-If the "force_mpx_mode" parameter is not specified, the correct mono-only
-mode will be chosen based on the TV band. However, the tuner will not
-receive stereo audio or bilingual broadcasts correctly.
-
-To pass the "force_band" or "force_mpx_mode" parameters to the
-wis-sony-tuner module, the following line must be added to the modprobe
-configuration file, which varies from one Linux distribution to another.
-
- options wis-sony-tuner force_band=B force_mpx_mode=2
-
-The above example would force the tuner to the PAL B/G TV band and receive
-stereo audio broadcasts on the A2 carrier.
-
-To verify that the configuration has been placed in the correct location,
-execute:
-
- $ modprobe -c | grep wis-sony-tuner
-
-If the configuration line appears, then modprobe will pass the parameters
-correctly the next time the wis-sony-tuner module is loaded into the
-kernel.
-
-
- 4. TESTING THE DRIVER
-
-
-Because few Linux applications are able to correctly capture from
-Video4Linux2 devices with only compressed formats supported, the new driver
-should be tested with the "gorecord" application in the apps/ directory.
-
-First connect a video source to the device, such as a DVD player or VCR.
-This will be captured to a file for testing the driver. If an input source
-is unavailable, a test file can still be captured, but the video will be
-black and the audio will be silent.
-
-This application will auto-detect the V4L2 and ALSA/OSS device names of the
-hardware and will record video and audio to an AVI file for a specified
-number of seconds. For example:
-
- $ apps/gorecord -duration 60 capture.avi
-
-If this application does not successfully record an AVI file, the error
-messages produced by gorecord and recorded in the system log (usually in
-/var/log/messages) should provide information to help resolve the problem.
-
-Supplying no parameters to gorecord will cause it to probe the available
-devices and exit. Use the -help flag for usage information.
-
-
- 5. USING THE DRIVER
-
-
-The V4L2 device implemented by the driver provides a standard compressed
-format API, within the following criteria:
-
- * Applications that only support the original Video4Linux1 API will not
- be able to communicate with this driver at all.
-
- * No raw video modes are supported, so applications like xawtv that
- expect only uncompressed video will not function.
-
- * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4.
-
- * MPEG video formats are delivered as Video Elementary Streams only.
- Program Stream (PS), Transport Stream (TS) and Packetized Elementary
- Stream (PES) formats are not supported.
-
- * Video parameters such as format and input port may not be changed while
- the encoder is active.
-
- * The audio capture device only functions when the video encoder is
- actively capturing video. Attempts to read from the audio device when
- the encoder is inactive will result in an I/O error.
-
- * The native format of the audio device is 48Khz 2-channel 16-bit
- little-endian PCM, delivered through the ALSA system. No audio
- compression is implemented in the hardware. ALSA may convert to other
- uncompressed formats on the fly.
-
-The include/ directory contains a C header file describing non-standard
-features of the GO7007SB encoder, which are described below:
-
-
- GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS
-
- These ioctls are used to negotiate general compression parameters.
-
- To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl
- with a pointer to a struct go7007_comp_params. If the driver is not
- set to MPEG format, the EINVAL error code will be returned.
-
- To change the current parameters, initialize all fields of a struct
- go7007_comp_params and call the GO7007_IOC_S_COMP_PARAMS ioctl with a
- pointer to this structure. The driver will return the current
- parameters with any necessary changes to conform to the limitations of
- the hardware or current compression mode. Any or all fields can be set
- to zero to request a reasonable default value. If the driver is not
- set to MPEG format, the EINVAL error code will be returned. When I/O
- is in progress, the EBUSY error code will be returned.
-
- Fields in struct go7007_comp_params:
-
- __u32 The maximum number of frames in each
- gop_size Group Of Pictures; i.e. the maximum
- number of frames minus one between
- each key frame.
-
- __u32 The maximum number of sequential
- max_b_frames bidirectionally-predicted frames.
- (B-frames are not yet supported.)
-
- enum go7007_aspect_ratio The aspect ratio to be encoded in the
- aspect_ratio meta-data of the compressed format.
-
- Choices are:
- GO7007_ASPECT_RATIO_1_1
- GO7007_ASPECT_RATIO_4_3_NTSC
- GO7007_ASPECT_RATIO_4_3_PAL
- GO7007_ASPECT_RATIO_16_9_NTSC
- GO7007_ASPECT_RATIO_16_9_PAL
-
- __u32 Bit-wise OR of control flags (below)
- flags
-
- Flags in struct go7007_comp_params:
-
- GO7007_COMP_CLOSED_GOP Only produce self-contained GOPs, used
- to produce streams appropriate for
- random seeking.
-
- GO7007_COMP_OMIT_SEQ_HEADER Omit the stream sequence header.
-
-
- GO7007IOC_S_MPEG_PARAMS, GO7007IOC_G_MPEG_PARAMS
-
- These ioctls are used to negotiate MPEG-specific stream parameters when
- the pixelformat has been set to V4L2_PIX_FMT_MPEG.
-
- To query the current parameters, call the GO7007IOC_G_MPEG_PARAMS ioctl
- with a pointer to a struct go7007_mpeg_params. If the driver is not
- set to MPEG format, the EINVAL error code will be returned.
-
- To change the current parameters, initialize all fields of a struct
- go7007_mpeg_params and call the GO7007_IOC_S_MPEG_PARAMS ioctl with a
- pointer to this structure. The driver will return the current
- parameters with any necessary changes to conform to the limitations of
- the hardware or selected MPEG mode. Any or all fields can be set to
- zero to request a reasonable default value. If the driver is not set
- to MPEG format, the EINVAL error code will be returned. When I/O is in
- progress, the EBUSY error code will be returned.
-
- Fields in struct go7007_mpeg_params:
-
- enum go7007_mpeg_video_standard
- mpeg_video_standard The MPEG video standard in which to
- compress the video.
-
- Choices are:
- GO7007_MPEG_VIDEO_MPEG1
- GO7007_MPEG_VIDEO_MPEG2
- GO7007_MPEG_VIDEO_MPEG4
-
- __u32 Bit-wise OR of control flags (below)
- flags
-
- __u32 The profile and level indication to be
- pali stored in the sequence header. This
- is only used as an indicator to the
- decoder, and does not affect the MPEG
- features used in the video stream.
- Not valid for MPEG1.
-
- Choices for MPEG2 are:
- GO7007_MPEG2_PROFILE_MAIN_MAIN
-
- Choices for MPEG4 are:
- GO7007_MPEG4_PROFILE_S_L0
- GO7007_MPEG4_PROFILE_S_L1
- GO7007_MPEG4_PROFILE_S_L2
- GO7007_MPEG4_PROFILE_S_L3
- GO7007_MPEG4_PROFILE_ARTS_L1
- GO7007_MPEG4_PROFILE_ARTS_L2
- GO7007_MPEG4_PROFILE_ARTS_L3
- GO7007_MPEG4_PROFILE_ARTS_L4
- GO7007_MPEG4_PROFILE_AS_L0
- GO7007_MPEG4_PROFILE_AS_L1
- GO7007_MPEG4_PROFILE_AS_L2
- GO7007_MPEG4_PROFILE_AS_L3
- GO7007_MPEG4_PROFILE_AS_L4
- GO7007_MPEG4_PROFILE_AS_L5
-
- Flags in struct go7007_mpeg_params:
-
- GO7007_MPEG_FORCE_DVD_MODE Force all compression parameters and
- bitrate control settings to comply
- with DVD MPEG2 stream requirements.
- This overrides most compression and
- bitrate settings!
-
- GO7007_MPEG_OMIT_GOP_HEADER Omit the GOP header.
-
- GO7007_MPEG_REPEAT_SEQHEADER Repeat the MPEG sequence header at
- the start of each GOP.
-
-
- GO7007IOC_S_BITRATE, GO7007IOC_G_BITRATE
-
- These ioctls are used to set and query the target bitrate value for the
- compressed video stream. The bitrate may be selected by storing the
- target bits per second in an int and calling GO7007IOC_S_BITRATE with a
- pointer to the int. The bitrate may be queried by calling
- GO7007IOC_G_BITRATE with a pointer to an int where the current bitrate
- will be stored.
-
- Note that this is the primary means of controlling the video quality
- for all compression modes, including V4L2_PIX_FMT_MJPEG. The
- VIDIOC_S_JPEGCOMP ioctl is not supported.

- Installing the WIS PCI Voyager Driver
----------------------------------------------------------------------------
-
-The WIS PCI Voyager driver requires several patches to the Linux 2.6.11.x
-kernel source tree before compiling the driver. These patches update the
-in-kernel SAA7134 driver to the newest development version and patch bugs
-in the TDA8290/TDA8275 tuner driver.
-
-The following patches must be downloaded from Gerd Knorr's website and
-applied in the order listed:

- http://dl.bytesex.org/patches/2.6.11-2/saa7134-update
-
-The following patches are included with this SDK and can be applied in any
-order:
-
- patches/2.6.11/saa7134-voyager.diff
- patches/2.6.11/tda8275-newaddr.diff
- patches/2.6.11/tda8290-ntsc.diff
-
-Check to make sure the CONFIG_VIDEO_SAA7134 option is enabled in the kernel
-configuration, and build and install the kernel.
-
-After rebooting into the new kernel, the GO7007 driver can be compiled and
-installed:
-
- $ make SAA7134_BUILD=y
- $ make install
- $ modprobe saa7134-go7007
-
-There will be two V4L video devices associated with the PCI Voyager. The
-first device (most likely /dev/video0) provides access to the raw video
-capture mode of the SAA7133 device and is used to configure the source
-video parameters and tune the TV tuner. This device can be used with xawtv
-or other V4L(2) video software as a standard uncompressed device.
-
-The second device (most likely /dev/video1) provides access to the
-compression functions of the GO7007. It can be tested using the gorecord
-application in the apps/ directory of this SDK:
-
- $ apps/gorecord -vdevice /dev/video1 -noaudio test.avi
-
-Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL),
-and the video standard must be specified to both the raw and the compressed
-video devices (xawtv and gorecord, for example).

-RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER
----------------------------------------------------------------------------
-
-Last updated: 5 November 2005
-
- - Release 0.9.7 includes new support for using udev to run fxload. The
- install script should automatically detect whether the old hotplug
- scripts or the new udev rules should be used. To force the use of
- hotplug, run "make install USE_UDEV=n". To force the use of udev, run
- "make install USE_UDEV=y".
-
- - Motion detection is supported but undocumented. Try the `modet` app
- for a demonstration of how to use the facility.
-
- - Using USB2.0 devices such as the TV402U with USB1.1 HCDs or hubs can
- cause buffer overruns and frame drops, even at low framerates, due to
- inconsistency in the bitrate control mechanism.
-
- - On devices with an SAA7115, including the Plextor ConvertX, video height
- values of 96, 128, 160, 192, 256, 320, and 384 do not work in NTSC mode.
- All valid heights up to 512 work correctly in PAL mode.
-
- - The WIS Star Trek and PCI Voyager boards have no support yet for audio
- or the TV tuner.
