The 55 * sc->transform method is used to convert the commands into the appropriate 56 * format (if at all necessary). For example, UFI requires all commands to be 57 * 12 bytes in length amongst other things. 58 * 59 * The source code below is marked and can be split into a number of pieces 60 * (in this order): 61 * 62 * - probe/attach/detach 63 * - generic transfer routines 64 * - BBB 65 * - CBI 66 * - CBI_I (in addition to functions from CBI) 67 * - CAM (Common Access Method) 68 * - SCSI 69 * - UFI 70 * - 8070i 71 * 72 * The protocols are implemented using a state machine, for the transfers as 73 * well as for the resets. The state machine is contained in umass_*_state. 74 * The state machine is started through either umass_*_transfer or 75 * umass_*_reset. 76 * 77 * The reason for doing this is a) CAM performs a lot better this way and b) it 78 * avoids using tsleep from interrupt context (for example after a failed 79 * transfer). 80 */ 81 82 /* 83 * The SCSI related part of this driver has been derived from the 84 * dev/ppbus/vpo.c driver, by Nicolas Souchu (nsouch (at) freebsd.org). 85 * 86 * The CAM layer uses so called actions which are messages sent to the host 87 * adapter for completion. The actions come in through umass_cam_action. The 88 * appropriate block of routines is called depending on the transport protocol 89 * in use. When the transfer has finished, these routines call 90 * umass_cam_cb again to complete the CAM command. 91 */ 92 93 /* XXX Should we split the driver into a number of files? umass.c, 94 * umass_scsi.c, umass_8070.c, umass_ufi.c, umass_bbb.c, umass_cbi.c or 95 * something similar? 96 */ 97 98 #include "atapibus.h" 99 100 #include <sys/param.h> 101 #include <sys/systm.h> 102 #include <sys/kernel.h> 103 #include <sys/conf.h> 104 #if defined(__NetBSD__) || defined(__OpenBSD__) 105 #include <sys/buf.h> 106 #include <sys/device.h> 107 #include <sys/ioctl.h> 108 #include <sys/malloc.h> 109 #undef KASSERT 110 #define KASSERT(cond, msg) 111 #elif defined(__FreeBSD__) 112 #include <sys/module.h> 113 #include <sys/bus.h> 114 #include <machine/clock.h> 115 #endif 116 117 #include <dev/usb/usb.h> 118 #include <dev/usb/usbdi.h> 119 #include <dev/usb/usbdi_util.h> 120 #include <dev/usb/usbdevs.h> 121 122 #if defined(__FreeBSD__) 123 #include <cam/cam.h> 124 #include <cam/cam_ccb.h> 125 #include <cam/cam_sim.h> 126 #include <cam/cam_xpt_sim.h> 127 #include <cam/scsi/scsi_all.h> 128 #include <cam/scsi/scsi_da.h> 129 130 #ifdef UMASS_DO_CAM_RESCAN 131 #include <sys/devicestat.h> 132 #include <cam/cam_periph.h> 133 #endif 134 135 #elif defined(__NetBSD__) || defined(__OpenBSD__) 136 #include <sys/scsiio.h> 137 #include <dev/scsipi/scsi_all.h> 138 #include <dev/scsipi/scsipi_all.h> 139 #include <dev/scsipi/scsiconf.h> 140 141 #include <dev/scsipi/atapiconf.h> 142 143 #include <dev/scsipi/scsipi_disk.h> 144 #include <dev/scsipi/scsi_disk.h> 145 #include <dev/scsipi/scsi_changer.h> 146 147 #include <dev/ata/atavar.h> /* XXX */ 148 #include <sys/disk.h> /* XXX */ 149 #include <dev/scsipi/sdvar.h> /* XXX */ 150 #endif 151 152 #ifdef UMASS_DEBUG 153 #define DIF(m, x) if (umassdebug & (m)) do { x ; } while (0) 154 #define DPRINTF(m, x) if (umassdebug & (m)) logprintf x 155 #define UDMASS_UPPER 0x00008000 /* upper layer */ 156 #define UDMASS_GEN 0x00010000 /* general */ 157 #define UDMASS_SCSI 0x00020000 /* scsi */ 158 #define UDMASS_UFI 0x00040000 /* ufi command set */ 159 #define UDMASS_8070 0x00080000 /* 8070i command set */ 160 #define UDMASS_USB 0x00100000 /* USB general */ 161 #define UDMASS_BBB 0x00200000 /* Bulk-Only transfers */ 162 #define UDMASS_CBI 0x00400000 /* CBI transfers */ 163 #define UDMASS_ALL 0xffff0000 /* all of the above */ 164 165 #define UDMASS_XFER 0x40000000 /* all transfers */ 166 #define UDMASS_CMD 0x80000000 167 168 int umassdebug = 0; 169 #else 170 #define DIF(m, x) /* nop */ 171 #define DPRINTF(m, x) /* nop */ 172 #endif 173 174 175 /* Generic definitions */ 176 177 #define UFI_COMMAND_LENGTH 12 178 179 /* Direction for umass_*_transfer */ 180 #define DIR_NONE 0 181 #define DIR_IN 1 182 #define DIR_OUT 2 183 184 /* The transfer speed determines the timeout value */ 185 #define UMASS_DEFAULT_TRANSFER_SPEED 150 /* in kb/s, conservative est. */ 186 #define UMASS_FLOPPY_TRANSFER_SPEED 20 187 #define UMASS_ZIP100_TRANSFER_SPEED 650 188 189 #define UMASS_SPINUP_TIME 10000 /* ms */ 190 191 #ifdef __FreeBSD__ 192 /* device name */ 193 #define DEVNAME "umass" 194 #define DEVNAME_SIM "umass-" 195 196 #define UMASS_MAX_TRANSFER_SIZE 65536 197 198 /* CAM specific definitions */ 199 200 /* The bus id, whatever that is */ 201 #define UMASS_SCSI_BUS 0 202 203 /* All USB drives are 'connected' to one SIM (SCSI controller). umass3 204 * ends up being target 3 on that SIM.
