46 * The driver handles 3 Wire Protocols
47 * - Command/Bulk/Interrupt (CBI)
48 * - Command/Bulk/Interrupt with Command Completion Interrupt (CBI with CCI)
49 * - Mass Storage Bulk-Only (BBB)
50 * (BBB refers Bulk/Bulk/Bulk for Command/Data/Status phases)
51 *
52 * Over these wire protocols it handles the following command protocols
53 * - SCSI
54 * - UFI (floppy command set)
55 * - 8070i (ATAPI)
56 *
57 * UFI and 8070i (ATAPI) are transformed versions of the SCSI command set. The
58 * sc->transform method is used to convert the commands into the appropriate
59 * format (if at all necessary). For example, UFI requires all commands to be
60 * 12 bytes in length amongst 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 (ATAPI)
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@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 /*
97 * XXX Currently CBI with CCI is not supported because it bombs the system
98 * when the device is detached (low frequency interrupts are detached
99 * too late.
