The 69 * sc->sc_transform method is used to convert the commands into the appropriate 70 * format (if at all necessary).

The state machine is contained in umass_t_*_callback. 88 * The state machine is started through either umass_command_start() or 89 * umass_reset(). 90 * 91 * The reason for doing this is a) CAM performs a lot better this way and b) it 92 * avoids using tsleep from interrupt context (for example after a failed 93 * transfer). 94 */ 95 96 /* 97 * The SCSI related part of this driver has been derived from the 98 * dev/ppbus/vpo.c driver, by Nicolas Souchu (nsouch@FreeBSD.org). 99 * 100 * The CAM layer uses so called actions which are messages sent to the host 101 * adapter for completion. The actions come in through umass_cam_action. The 102 * appropriate block of routines is called depending on the transport protocol 103 * in use.
