UFI is a transformed 57 * version of the 8070i command set. The sc->transform method is used to 58 * convert the commands into the appropriate format (if at all necessary). 59 * For example, ATAPI requires all commands to be 12 bytes in length amongst 60 * other things. 61 * 62 * The source code below is marked and can be split into a number of pieces 63 * (in this order): 64 * 65 * - probe/attach/detach 66 * - generic transfer routines 67 * - BBB 68 * - CBI 69 * - CBI_I (in addition to functions from CBI) 70 * - CAM (Common Access Method) 71 * - SCSI 72 * - UFI 73 * - 8070i 74 * 75 * The protocols are implemented using a state machine, for the transfers as 76 * well as for the resets. The state machine is contained in umass_*_state. 77 * The state machine is started through either umass_*_transfer or 78 * umass_*_reset. 79 * 80 * The reason for doing this is a) CAM performs a lot better this way and b) it 81 * avoids using tsleep from interrupt context (for example after a failed 82 * transfer). 83 */ 84 85 /* 86 * The SCSI related part of this driver has been derived from the 87 * dev/ppbus/vpo.c driver, by Nicolas Souchu (nsouch (at) freebsd.org). 88 * 89 * The CAM layer uses so called actions which are messages sent to the host 90 * adapter for completion. The actions come in through umass_cam_action. The 91 * appropriate block of routines is called depending on the transport protocol 92 * in use. When the transfer has finished, these routines call 93 * umass_cam_cb again to complete the CAM command. 94 */ 95 96 #include <sys/cdefs.h> 97 __KERNEL_RCSID(0, "$NetBSD: umass.c,v 1.93 2003/01/01 15:55:48 toshii Exp $");
