From 7955f03d18d14d18188f94581a4ea336c94b1e2d Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 22 Jul 2014 06:21:37 +0200 Subject: [PATCH] [media] go7007: move out of staging into drivers/media/usb. Now that the custom motion detection API in this driver has been replaced with a standard API there is no reason anymore to keep it in staging. So (finally!) move it to drivers/media/usb.

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//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 . -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//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/i2c-tuner - http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner2 - http://dl.bytesex.org/patches/2.6.11-2/v4l2-api-mpeg - 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. diff --git a/drivers/staging/media/go7007/saa7134-go7007.c b/drivers/staging/media/go7007/saa7134-go7007.c deleted file mode 100644 index b137432fa0e4..000000000000 --- a/drivers/staging/media/go7007/saa7134-go7007.c +++ /dev/null @@ -1,560 +0,0 @@ -/* - * Copyright (C) 2005-2006 Micronas USA 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.
