SCSI_HBA_PKT_COMP(9F)SCSI_HBA_PKT_COMP(9F)NAMEscsi_hba_pkt_comp - scsi_pkt completion routine
SYNOPSIS
#include <sys/scsi/scsi.h>
void scsi_hba_pkt_comp(struct scsi_pkt *pkt);
PARAMETERS
pkt
Pointer to a scsi_pkt(9S) structure.
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
DESCRIPTION
After filling in scsi_pkt(9S) fields with packet completion informa‐
tion, an HBA driver should call the scsi_hba_pkt_comp() function. This
function is the recommended way for an HBA driver to signal completion
of a scsi_pkt structure. Use is mandatory for HBA drivers that use
tran_setup_pkt(9E).
Calling the scsi_hba_pkt_comp() function allows SCSA to observe, and
possibly react to, the completion of a scsi_pkt request.
A call to the scsi_hba_pkt_comp() function will always result in a call
to the pkt_comp() callback function defined in scsi_pkt(9S). This
pkt_comp() callback may, however, occur after return from
scsi_hba_pkt_comp(), and may occur from a different thread executing on
a different CPU.
CONTEXT
The scsi_hba_pkt_comp() function can be called from user, interrupt, or
kernel context.

HBA driver calls scsi_hba_pkt_comp() instead of calling scsi_pkt(9S)
pkt_comp directly.
