Intro -- introduction to entry point routines for hot plug controller drivers

Synopsis

   #include <sys/types.h>
   #include <sys/hpci.h>
   #include <sys/ddi.h>

Description

This section documents the Hot Plug Controller Interface functions that are used to implement hot plug controller drivers. Drivers that use these functions must include the following line in their Master(4dsp) files:

   $interface hpci 1

Usage

Hot-plug controller drivers use standard DDI entry point routines, and entry point routines that are unique to the Hot-plug Controller Interface (HPCI). Three callback routines that are unique to HPCI are declared in the hpci_hpcd_t(D4hpci) structure that is populated in the CFG_ADD subfunction of the config(D2hpci) entry point routine.
