The 57 * sc->transform method is used to convert the commands into the appropriate 58 * format (if at all necessary). For example, UFI requires all commands to be 59 * 12 bytes in length amongst other things. 60 * 61 * The source code below is marked and can be split into a number of pieces 62 * (in this order): 63 * 64 * - probe/attach/detach 65 * - generic transfer routines 66 * - BBB 67 * - CBI 68 * - CBI_I (in addition to functions from CBI) 69 * - CAM (Common Access Method) 70 * - SCSI 71 * - UFI 72 * - 8070i 73 * 74 * The protocols are implemented using a state machine, for the transfers as 75 * well as for the resets. The state machine is contained in umass_*_state. 76 * The state machine is started through either umass_*_transfer or 77 * umass_*_reset. 78 * 79 * The reason for doing this is a) CAM performs a lot better this way and b) it 80 * avoids using tsleep from interrupt context (for example after a failed 81 * transfer). 82 */ 83 84 /* 85 * The SCSI related part of this driver has been derived from the 86 * dev/ppbus/vpo.c driver, by Nicolas Souchu (nsouch (at) freebsd.org). 87 * 88 * The CAM layer uses so called actions which are messages sent to the host 89 * adapter for completion. The actions come in through umass_cam_action. The 90 * appropriate block of routines is called depending on the transport protocol 91 * in use. When the transfer has finished, these routines call 92 * umass_cam_cb again to complete the CAM command. 93 */ 94 95 /* XXX Should we split the driver into a number of files? umass.c, 96 * umass_scsi.c, umass_8070.c, umass_ufi.c, umass_bbb.c, umass_cbi.c or 97 * something similar? 98 */ 99 100 #include "atapibus.h" 101 102 #include <sys/param.h> 103 #include <sys/systm.h> 104 #include <sys/kernel.h> 105 #include <sys/conf.h> 106 #if defined(__NetBSD__) || defined(__OpenBSD__) 107 #include <sys/buf.h> 108 #include <sys/device.h> 109 #include <sys/ioctl.h> 110 #include <sys/malloc.h> 111 #undef KASSERT 112 #define KASSERT(cond, msg) 113 #elif defined(__FreeBSD__) 114 #include <sys/module.h> 115 #include <sys/bus.h> 116 #include <machine/clock.h> 117 #endif 118 119 #include <dev/usb/usb.h> 120 #include <dev/usb/usbdi.h> 121 #include <dev/usb/usbdi_util.h> 122 #include <dev/usb/usbdevs.h> 123 124 #if defined(__FreeBSD__) 125 #include <cam/cam.h> 126 #include <cam/cam_ccb.h> 127 #include <cam/cam_sim.h> 128 #include <cam/cam_xpt_sim.h> 129 #include <cam/scsi/scsi_all.h> 130 #include <cam/scsi/scsi_da.h> 131 132 #ifdef UMASS_DO_CAM_RESCAN 133 #include <sys/devicestat.h> 134 #include <cam/cam_periph.h> 135 #endif 136 137 #elif defined(__NetBSD__) || defined(__OpenBSD__) 138 #include <sys/scsiio.h> 139 #include <dev/scsipi/scsi_all.h> 140 #include <dev/scsipi/scsipi_all.h> 141 #include <dev/scsipi/scsiconf.h> 142 143 #include <dev/scsipi/atapiconf.h> 144 145 #include <dev/scsipi/scsipi_disk.h> 146 #include <dev/scsipi/scsi_disk.h> 147 #include <dev/scsipi/scsi_changer.h> 148 149 #define SHORT_INQUIRY_LENGTH 36 /* XXX */ 150 151 #include <dev/ata/atavar.h> /* XXX */ 152 #include <sys/disk.h> /* XXX */ 153 #include <dev/scsipi/sdvar.h> /* XXX */ 154 #endif 155 156 #ifdef UMASS_DEBUG 157 #define DIF(m, x) if (umassdebug & (m)) do { x ; } while (0) 158 #define DPRINTF(m, x) if (umassdebug & (m)) logprintf x 159 #define UDMASS_UPPER 0x00008000 /* upper layer */ 160 #define UDMASS_GEN 0x00010000 /* general */ 161 #define UDMASS_SCSI 0x00020000 /* scsi */ 162 #define UDMASS_UFI 0x00040000 /* ufi command set */ 163 #define UDMASS_8070 0x00080000 /* 8070i command set */ 164 #define UDMASS_USB 0x00100000 /* USB general */ 165 #define UDMASS_BBB 0x00200000 /* Bulk-Only transfers */ 166 #define UDMASS_CBI 0x00400000 /* CBI transfers */ 167 #define UDMASS_ALL 0xffff0000 /* all of the above */ 168 169 #define UDMASS_XFER 0x40000000 /* all transfers */ 170 #define UDMASS_CMD 0x80000000 171 172 int umassdebug = 0; 173 #else 174 #define DIF(m, x) /* nop */ 175 #define DPRINTF(m, x) /* nop */ 176 #endif 177 178 179 /* Generic definitions */ 180 181 #define UFI_COMMAND_LENGTH 12 182 183 /* Direction for umass_*_transfer */ 184 #define DIR_NONE 0 185 #define DIR_IN 1 186 #define DIR_OUT 2 187 188 /* The transfer speed determines the timeout value */ 189 #define UMASS_DEFAULT_TRANSFER_SPEED 150 /* in kb/s, conservative est. */ 190 #define UMASS_FLOPPY_TRANSFER_SPEED 20 191 #define UMASS_ZIP100_TRANSFER_SPEED 650 192 193 #define UMASS_SPINUP_TIME 10000 /* ms */ 194 195 #ifdef __FreeBSD__ 196 /* device name */ 197 #define DEVNAME "umass" 198 #define DEVNAME_SIM "umass-" 199 200 #define UMASS_MAX_TRANSFER_SIZE 65536 201 202 /* CAM specific definitions */ 203 204 /* The bus id, whatever that is */ 205 #define UMASS_SCSI_BUS 0 206 207 /* All USB drives are 'connected' to one SIM (SCSI controller). umass3 208 * ends up being target 3 on that SIM.
