Bertin and Johannes Erdfelt 30 * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler & 31 * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink 32 * Updates to driver completed by Dwaine P. Garden 33 * 34 * 35 * TODO: 36 * - use submit_urb for all setup packets 37 * - Fix memory settings for nt1004. It is 4 times as big as the 38 * nt1003 memory. 39 * - Add audio on endpoint 3 for nt1004 chip. Seems impossible, needs a codec interface. Which one? 40 * - Clean up the driver. 41 * - optimization for performance. 42 * - Add Videotext capability (VBI). Working on it..... 43 * - Check audio for other devices 44 * 45 */ 46 47#include <linux/version.h> 48#include <linux/kernel.h> 49#include <linux/sched.h> 50#include <linux/list.h> 51#include <linux/timer.h> 52#include <linux/slab.h> 53#include <linux/mm.h> 54#include <linux/utsname.h> 55#include <linux/highmem.h> 56#include <linux/smp_lock.h> 57#include <linux/videodev.h> 58#include <linux/vmalloc.h> 59#include <linux/module.h> 60#include <linux/init.h> 61#include <linux/spinlock.h> 62#include <asm/io.h> 63#include <linux/videodev2.h> 64#include <linux/video_decoder.h> 65#include <linux/i2c.h> 66 67#include <media/saa7115.h> 68#include <media/v4l2-common.h> 69#include <media/tuner.h> 70#include <media/audiochip.h> 71 72#include <linux/moduleparam.h> 73#include <linux/workqueue.h> 74 75#ifdef CONFIG_KMOD 76#include <linux/kmod.h> 77#endif 78 79#include "usbvision.h" 80 81#define DRIVER_AUTHOR "Joerg Heckenbach <joerg@heckenbach-aw.de>, Dwaine Garden <DwaineGarden@rogers.com>" 82#define DRIVER_NAME "usbvision" 83#define DRIVER_ALIAS "USBVision" 84#define DRIVER_DESC "USBVision USB Video Device Driver for Linux" 85#define DRIVER_LICENSE "GPL" 86#define USBVISION_DRIVER_VERSION_MAJOR 0 87#define USBVISION_DRIVER_VERSION_MINOR 9 88#define USBVISION_DRIVER_VERSION_PATCHLEVEL 9 89#define USBVISION_DRIVER_VERSION KERNEL_VERSION(USBVISION_DRIVER_VERSION_MAJOR,USBVISION_DRIVER_VERSION_MINOR,USBVISION_DRIVER_VERSION_PATCHLEVEL) 90#define USBVISION_VERSION_STRING __stringify(USBVISION_DRIVER_VERSION_MAJOR) "." __stringify(USBVISION_DRIVER_VERSION_MINOR) "." __stringify(USBVISION_DRIVER_VERSION_PATCHLEVEL) 91 92#define ENABLE_HEXDUMP 0 /* Enable if you need it */ 93 94 95#define USBVISION_DEBUG /* Turn on debug messages */ 96 97#ifdef USBVISION_DEBUG 98 #define PDEBUG(level, fmt, args...) \ 99 if (video_debug & (level)) info("[%s:%d] " fmt, __PRETTY_FUNCTION__, __LINE__ , ## args) 100#else 101 #define PDEBUG(level, fmt, args...) do {} while(0) 102#endif 103 104#define DBG_IOCTL 1<<0 105#define DBG_IO 1<<1 106#define DBG_PROBE 1<<2 107#define DBG_FUNC 1<<3 108 109//String operations 110#define rmspace(str) while(*str==' ') str++; 111#define goto2next(str) while(*str!=' ') str++; while(*str==' ') str++; 112 113 114static int usbvision_nr = 0; // sequential number of usbvision device 115 116static struct usbvision_v4l2_format_st usbvision_v4l2_format[] = { 117 { 1, 1, 8, V4L2_PIX_FMT_GREY , "GREY" }, 118 { 1, 2, 16, V4L2_PIX_FMT_RGB565 , "RGB565" }, 119 { 1, 3, 24, V4L2_PIX_FMT_RGB24 , "RGB24" }, 120 { 1, 4, 32, V4L2_PIX_FMT_RGB32 , "RGB32" }, 121 { 1, 2, 16, V4L2_PIX_FMT_RGB555 , "RGB555" }, 122 { 1, 2, 16, V4L2_PIX_FMT_YUYV , "YUV422" }, 123 { 1, 2, 12, V4L2_PIX_FMT_YVU420 , "YUV420P" }, // 1.5 ! 124 { 1, 2, 16, V4L2_PIX_FMT_YUV422P , "YUV422P" } 125}; 126 127/* supported tv norms */ 128static struct usbvision_tvnorm tvnorms[] = { 129 { 130 .name = "PAL", 131 .id = V4L2_STD_PAL, 132 }, { 133 .name = "NTSC", 134 .id = V4L2_STD_NTSC, 135 }, { 136 .name = "SECAM", 137 .id = V4L2_STD_SECAM, 138 }, { 139 .name = "PAL-M", 140 .id = V4L2_STD_PAL_M, 141 } 142}; 143 144#define TVNORMS ARRAY_SIZE(tvnorms) 145 146// Function prototypes 147static void usbvision_release(struct usb_usbvision *usbvision); 148 149// Default initalization of device driver parameters 150static int isocMode = ISOC_MODE_COMPRESS; // Set the default format for ISOC endpoint 151static int video_debug = 0; // Set the default Debug Mode of the device driver 152static int PowerOnAtOpen = 1; // Set the default device to power on at startup 153static int video_nr = -1; // Sequential Number of Video Device 154static int radio_nr = -1; // Sequential Number of Radio Device 155static int vbi_nr = -1; // Sequential Number of VBI Device 156static char *CustomDevice=NULL; // Set as nothing.... 157 158// Grab parameters for the device driver 159 160#if defined(module_param) // Showing parameters under SYSFS 161module_param(isocMode, int, 0444); 162module_param(video_debug, int, 0444); 163module_param(PowerOnAtOpen, int, 0444); 164module_param(video_nr, int, 0444); 165module_param(radio_nr, int, 0444); 166module_param(vbi_nr, int, 0444); 167module_param(CustomDevice, charp, 0444); 168#else // Old Style 169MODULE_PARAM(isocMode, "i"); 170MODULE_PARM(video_debug, "i"); // Grab the Debug Mode of the device driver 171MODULE_PARM(adjustCompression, "i"); // Grab the compression to be adaptive 172MODULE_PARM(PowerOnAtOpen, "i"); // Grab the device to power on at startup 173MODULE_PARM(SwitchSVideoInput, "i"); // To help people with Black and White output with using s-video input.
