81 81 .sp
82 82 .SS "scsi_hba_attach_setup(\|)"
83 83 .sp
84 84 .LP
85 85 The \fBscsi_hba_attach_setup()\fR function registers the
86 86 \fIhba_dma_attr\fR DMA attributes and the \fIhba_tran\fR transport vectors of
87 87 each instance of the HBA device defined by \fIdip\fR. The HBA driver can pass
88 88 different DMA attributes and the transport vectors for each
89 89 instance of the device to support any constraints imposed by the HBA itself.
90 90 .sp
91 91 .LP
92 92 The \fBscsi_hba_attach_setup()\fR function uses the
93 93 \fBdev_bus_ops\fR field in the \fBdev_ops\fR(9S) structure. The HBA driver
94 94 should initialize this field to \fINULL\fR before calling
95 95 \fBscsi_hba_attach_setup()\fR.
96 96 .sp
97 97 .LP
98 98 If \fBSCSI_HBA_TRAN_CLONE\fR is requested in \fIhba_flags\fR, the
99 99 \fBhba_tran\fR structure is cloned once for each target that is attached to the
100 100 HBA. The structure is cloned before the \fBtran_tgt_init\fR(9E) entry point is
101 101 called to initialize a target. At all subsequent HBA entry points, including
102 102 \fBtran_tgt_init\fR(9E), the \fBscsi_hba_tran_t\fR structure passed as an
103 103 argument or found in a \fBscsi_address\fR structure is the cloned
104 104 \fBscsi_hba_tran_t\fR structure,which allows the HBA to use the
105 105 \fBtran_tgt_private\fR field in the \fBscsi_hba_tran_t\fR structure to point to
106 106 per-target data. The HBA should free only the same \fBscsi_hba_tran_t\fR
107 107 structure allocated when the HBA detaches. All cloned \fBscsi_hba_tran_t\fR
108 108 structures that are allocated by the system are freed by the system.
109 109 .sp
110 110 .LP
111 111 The flags \fBSCSI_HBA_TRAN_CDB\fR and \fBSCSI_HBA_TRAN_SCB\fR are only valid
112 112 when \fBtran_setup_pkt()\fR is used. See \fBtran_setup_pkt\fR(9E) for
113 113 information on using these flags.
114 114 .sp
115 115 .LP
116 116 The \fBscsi_hba_attach_setup()\fR function attaches
117 117 a number of integer-valued properties to \fIdip\fR, unless properties of the
118 118 same name are already attached to the node. An HBA driver should retrieve these
119 119 configuration parameters via \fBddi_prop_get_int\fR(9F), and respect any
120 120 settings for features provided the HBA.
