8 ib \- InfiniBand device driver configuration files
12 The InfiniBand (IB) bus is an I/O transport based on switched fabrics. IB
13 devices are managed by the \fBib\fR(7D) nexus driver. There are three
14 categories of InfiniBand devices:
19 IB port/IB VPPA/IB HCA_SVC devices
35 The IB port/IB VPPA/IB HCA_SVC devices are enumerated by way of the
36 \fBib.conf\fR file. See \fBib\fR(7D).
39 The IB IOC devices are enumerated using the InfiniBand Device management class.
43 For devices not in these two categories, most notably IB Pseudo devices, the
44 driver must provide configuration files to inform the system of the IB devices
45 to be created. Configuration parameters are represented in the form of name
46 value pairs you can retrieve using the DDI property interfaces. See
47 \fBddi_prop_op\fR(9F) for details.
50 Configuration files for IB device drivers must identify the parent driver
51 explicitly as \fBib\fR, and must create a string array property called
52 \fBunit-address\fR which is unique to this entry in the configuration file.
53 Drivers name \fBibport\fR and \fBioc\fR are reserved by \fBib\fR(7D) and should
57 Each entry in the configuration file creates a prototype \fBdevinfo\fR node.
58 Each node is assigned a unit address which is determined by the value of the
59 \fBunit-address\fR property. This property is only applicable to children of
60 the IB parent and is required. See \fBdriver.conf\fR(4) for further details on
61 configuration file syntax.
65 Example 1: Sample configuration file
68 Here is a configuration file called \fBibgen.conf\fR for an IB device driver
69 that implements a generic IB driver. This file creates a node called
