NAME

scsi_free_consistent_buf - free a previously allocated SCSI DMA I/O

SYNOPSIS

#include <sys/scsi/scsi.h>


void scsi_free_consistent_buf(struct buf *bp);

INTERFACE LEVEL

illumos DDI specific (illumos DDI).

PARAMETERS

bp
Pointer to the buf(9S) structure.

DESCRIPTION

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

CONTEXT

The scsi_free_consistent_buf() function can be called from user,
interrupt, or kernel context.

SEE ALSO

freerbuf(9F), scsi_alloc_consistent_buf(9F), buf(9S)


Writing Device Drivers

WARNING

The scsi_free_consistent_buf() function 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.
