.TH SCSI_HBA_PKT_COMP 9F "Jan 29, 2009"
.SH NAME
scsi_hba_pkt_comp \- scsi_pkt completion routine
.SH SYNOPSIS
.nf
#include <sys/scsi/scsi.h>

\fBvoid\fR \fBscsi_hba_pkt_comp\fR(\fBstruct scsi_pkt *\fR\fIpkt\fR);
.fi

.SH PARAMETERS
.ne 2
.na
\fB\fIpkt\fR\fR
.ad
.RS 7n
Pointer to a \fBscsi_pkt\fR(9S) structure.
.RE

.SH INTERFACE LEVEL
illumos DDI specific (illumos DDI).
.SH DESCRIPTION
After filling in \fBscsi_pkt\fR(9S) fields with packet completion information,
an HBA driver should call the \fBscsi_hba_pkt_comp()\fR function. This function
is the recommended way for an HBA driver to signal completion of a
\fBscsi_pkt\fR structure.  Use is mandatory for HBA drivers that use
\fBtran_setup_pkt\fR(9E).
.sp
.LP
Calling the \fBscsi_hba_pkt_comp()\fR function allows SCSA to observe, and
possibly react to, the completion of a \fBscsi_pkt\fR request.
.sp
.LP
A call to the \fBscsi_hba_pkt_comp()\fR function will always result in a call
to the \fIpkt_comp\fR() callback function defined in \fBscsi_pkt\fR(9S). This
\fIpkt_comp\fR() callback may, however, occur after return from
\fBscsi_hba_pkt_comp()\fR, and may occur from a different thread executing on a
different CPU.
.SH CONTEXT
The \fBscsi_hba_pkt_comp()\fR function can be called from user, interrupt, or
kernel context.
.SH ATTRIBUTES

.SH NOTES
HBA driver calls \fBscsi_hba_pkt_comp()\fR instead of calling
\fBscsi_pkt\fR(9S) \fIpkt_comp\fR directly.
