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_HOTPLUG - Support for hot-pluggable devices + CONFIG_MODULES - Enable loadable module support + CONFIG_KMOD - Automatic kernel module loading + 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_DEVICEFS - USB device filesystem + 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.

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. diff --git a/linux/drivers/staging/go7007/s2250-board.c b/linux/drivers/staging/go7007/s2250-board.c new file mode 100644 index 000000000..f35f0776c --- /dev/null +++ b/linux/drivers/staging/go7007/s2250-board.c @@ -0,0 +1,620 @@ +/* + * Copyright (C) 2008 Sensoray Company Inc. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License (Version 2) as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
