tran_sync_pkt - SCSI HBA memory synchronization entry point
#include
<sys/scsi/scsi.h>
void prefixtran_sync_pkt(struct scsi_address *ap, struct
scsi_pkt *pkt);
Solaris architecture specific (Solaris DDI).
- ap
- A pointer to a scsi_address(9S)
structure.
- pkt
- A pointer to
a scsi_pkt(9S)
structure.
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 CPU’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.
