scsi_free_consistent_buf(9F)

NAME

scsi_free_consistent_buf - free a previously allocated SCSI DMA I/O buffer

#include <sys/scsi/scsi.h> void scsi_free_consistent_buf(struct buf *bp);

Solaris DDI specific (Solaris DDI).

scsi_free_consistent_buf() frees a buffer header and consistent data buffer that was previously allocated using scsi_alloc_consistent_buf(9F).

scsi_free_consistent_buf() may be called from either the user or the interrupt levels.

scsi_free_consistent_buf() will call freerbuf(9F) to free the buf(9S) that was allocated before or during the call to scsi_alloc_consistent_buf(9F).

If consistent memory is bound to a scsi_pkt(9S), the pkt should be destroyed before freeing the consistent memory.
