tran_hba_dip
dev_info pointer to the HBA that supplies
the scsi_hba_tran structure.
tran_hba_private
Private pointer that the HBA driver can use to
refer to the device's soft state structure.
tran_tgt_private
Private pointer that the
HBA can use to refer to
per-target specific data. This field can only be used when the
SCSI_HBA_TRAN_CLONE flag is specified in
scsi_hba_attach(9F). In
this case, the
HBA driver must initialize this field in its
tran_tgt_init(9E) entry point.
tran_sd
tran_tgt_init
Function entry that allows per-target HBA
initialization, if necessary.
tran_tgt_probe
Function entry that allows per-target
scsi_probe(9F) customization, if necessary.
tran_tgt_free
Function entry that allows per-target HBA
deallocation, if necessary.
tran_start
Function entry that starts a SCSI command
execution on the HBA hardware.
tran_reset
Function entry that resets a SCSI bus or target
device.
tran_abort
Function entry that aborts one SCSI command, or
all pending SCSI commands.
tran_getcap
Function entry that retrieves a SCSI
capability.
tran_setcap
Function entry that sets a SCSI capability.
tran_init_pkt
Function entry that allocates a scsi_pkt
structure.
tran_destroy_pkt
Function entry that frees a scsi_pkt structure
allocated by tran_init_pkt.
tran_dmafree
Function entry that frees DMA resources that were
previously allocated by tran_init_pkt. Not called for HBA
drivers that provide a tran_setup_pkt entry point.
tran_sync_pkt
Synchronizes data in pkt after a data transfer has
been completed. Not called for HBA drivers that provide a
tran_setup_pkt entry point.
tran_reset_notify
Function entry that allows a target to register a bus
reset notification request with the HBA driver.
tran_bus_reset
Function entry that resets the SCSI bus without
resetting targets.
tran_quiesce
Function entry that waits for all outstanding commands to
complete and blocks (or queues) any I/O requests issued.
tran_unquiesce
Function entry that allows I/O activities to
resume on the SCSI bus.
tran_setup_pkt
tran_teardown_pkt
Entry point that releases resources allocated by
tran_setup_pkt.
tran_pkt_constructor
Additional optional entry point that performs the actions
of a constructor. See
tran_setup_pkt(9E).
tran_pkt_destructor
Additional optional entry point that performs the actions
of a destructor. See
tran_setup_pkt(9E).
tran_hba_len
tran_interconnect_type
Integer value that denotes the interconnect type of the
transport as defined in the services.h header file.
