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 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(7D).
The IB IOC devices are enumerated using the InfiniBand Device manage‐
ment class. See ibdm(7D).
For devices not in these two categories, most notably IB Pseudo
devices, the driver must provide configuration files to inform the sys‐
tem of the IB devices to be created. Configuration parameters are rep‐
resented 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 fur‐
ther 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.
