Kernel Functions for Drivers                scsi_hba_pkt_comp(9F)



NAME
     scsi_hba_pkt_comp - scsi_pkt completion routine

SYNOPSIS
     #include 

     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
     information,    an    HBA    driver    should    call    the
     scsi_hba_pkt_comp() function. This function  is  the  recom-
     mended  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.

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