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(4D) nexus driver. There are three cat‐
       egories of InfiniBand devices:

           o      IB port/IB VPPA/IB HCA_SVC devices


           o      IB IOC devices


           o      IB Pseudo devices



       The IB port/IB VPPA/IB HCA_SVC devices are enumerated  by  way  of  the
       ib.conf file. See ib(4D).


       The  IB  IOC devices are enumerated using the InfiniBand Device manage‐
       ment class. See ibdm(4D).


       For devices not in these two categories, most  notably  IB  Pseudo  de‐
       vices, the driver must provide configuration files to inform the system
       of  the  IB  devices to be created. Configuration parameters are repre‐
       sented 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 dri‐
       ver  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(4D) 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 chil‐
       dren of the IB parent and is required. See driver.conf(5)  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.
