#include <sys/scsi/scsi.h> void prefixtran_sync_pkt(struct scsi_address *ap, struct scsi_pkt *pkt);
Solaris architecture specific (Solaris DDI).
The tran_sync_pkt() vector in the scsi_hba_tran(9S) structure must be initialized during the HBA driver's attach(9E) to point to an HBA driver entry point to be called when a target driver calls scsi_sync_pkt(9F).
tran_sync_pkt() must synchronize a HBA's or device's view of the data associated with the pkt, typically by calling ddi_dma_sync(9F). The operation may also involve HBA hardware-specific details, such as flushing I/O caches, or stalling until hardware buffers have been drained.
A target driver may call tran_sync_pkt() on packets for which no DMA resources were allocated.
