Solaris architecture specific (Solaris DDI).

dip

Pointer to a dev_info structure, defining the HBA driver instance.

flag

Flag modifiers. The only possible flag value is SCSI_HBA_CANSLEEP (memory allocation may sleep).

hba_tran

Pointer to a scsi_hba_tran(9S) structure.

For scsi_hba_tran_alloc():

scsi_hba_tran_alloc() allocates a scsi_hba_tran(9S) structure for a HBA driver. The HBA must use this structure to register its transport vectors with the system by using scsi_hba_attach_setup(9F).

If the flag SCSI_HBA_CANSLEEP is set in flags, scsi_hba_tran_alloc() may sleep when allocating resources; otherwise it may not sleep, and callers should be prepared to deal with allocation failures.

For scsi_hba_tran_free():

scsi_hba_tran_free() is used to free the scsi_hba_tran(9S) structure allocated by scsi_hba_tran_alloc().

scsi_hba_tran_alloc() returns a pointer to the allocated transport structure, or NULL if no space is available.

scsi_hba_tran_alloc() can be called from user or interrupt context. Drivers must not allow scsi_hba_tran_alloc() to sleep if called from an interrupt routine.

scsi_hba_tran_free() can be called from user or interrupt context.
