NAME

       ib - InfiniBand device driver configuration files

DESCRIPTION

       The  InfiniBand (IB) bus is an I/O transport based on switched  fabrics. IB devices are managed by the ib(7D) nexus driver. There are three
       categories of InfiniBand devices:

	 o  IB	port/IB VPPA/IB HCA_SVC devices

	 o  IB IOC devices

	 o  IB Psuedo devices

       The IB  port/IB VPPA/IB HCA_SVC devices are enumerated by way of the ib.conf file. See ib(7D).

       The IB IOC devices are enumerated using the InfiniBand Device management class. See ibdm(7D).

       For devices not in these two categories, most notably IB Psuedo devices, the driver must provide configuration files to inform  the  system
       of  the	IB  devices to be created. Configuration parameters are represented in the form of name value pairs you can retrieve using the DDI
       property interfaces.  See ddi_prop_op(9F) for details.

       Configuration files for IB device drivers must identify the parent driver explicitly as "ib," and  must	create	a  string  array  property
       called  "unit-address"  which is unique to this entry in the configuration file. Drivers name "ibport" and "ioc" are reserved by ib(7D) and
       should not be used.

       Each entry in the configuration file creates a prototype devinfo node. Each node is assigned a unit address  which  is  determined  by  the
       value  of  the "unit-address"  property. This property is only applicable to children of the IB parent and is required.	See driver.conf(4)
       for further details on configuration file syntax.

EXAMPLES

       Example 1: Sample configuration file

       Here is a configuration file called ibgen.conf for an IB  device driver that implements a generic IB  driver.  This  file  creates  a  node
       called "ibgen."
