hpci_hpcd_t -- hot plug controller data structure

Syntax

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

Description

The hpci_hpcd_t structure provides information about the hot plug controller driver to the hpci driver.

Structure definitions

The hpci_hpcd_t structure contains the following members:

   void               *private;
   hpci_op_t          modify_callback;
   hpcd_lock_op_t	   lock_callback;
   hpcd_unlock_op_t   unlock_callback;
   int            	   buscnt;
   hpci_bus_t         *bus_list;

Structure members

The members of the hpci_hpcd_t structure are defined as:

*private: to be used by the hpcd driver instance itself.
modify_callback: address of the modify_callback(D2hpci) routine to be used by the kernel.
lock_callback: address of the hpcd driver's lock_callback(D2hpci) interface lock routine.
unlock_callback: address of the hpcd driver's unlock_callback(D2hpci) interface unlock routine.
buscnt: total number of busses controlled by this hpcd instance.
buslist: pointer to the hpci_bus_t(D4hpci) structure that lists the busses controlled by this hpcd instance.

Usage

The hpci_hpcd_t structure is allocated and populated by the hpci_attach(D3hpci) function.
