NAME

6       ib - InfiniBand device driver configuration files
7

DESCRIPTION

9       The InfiniBand (IB) bus is an I/O transport based on switched  fabrics.
10       IB devices are managed by the ib(7D) nexus driver. There are three cat‐
11       egories of InfiniBand devices:
12
13           o      IB  port/IB VPPA/IB HCA_SVC devices
14
15           o      IB IOC devices
16
17           o      IB Pseudo devices
18
19
20       The  IB   port/IB  VPPA/IB HCA_SVC devices are enumerated by way of the
21       ib.conf file. See ib(7D).
22
23
24       The IB IOC devices are enumerated using the InfiniBand  Device  manage‐
25       ment class. See ibdm(7D).
26
27
28       For  devices  not  in  these  two  categories,  most  notably IB Pseudo
29       devices, the driver must provide configuration files to inform the sys‐
30       tem of the IB  devices to be created. Configuration parameters are rep‐
31       resented in the form of name value pairs you can retrieve using the DDI
32       property interfaces. See ddi_prop_op(9F) for details.
33
34
35       Configuration  files  for  IB  device  drivers must identify the parent
36       driver explicitly as ib, and must create a string array property called
37       unit-address  which  is unique to this entry in the configuration file.
38       Drivers name ibport and ioc are reserved by ib(7D) and  should  not  be
39       used.
40
41
42       Each  entry in the configuration file creates a prototype devinfo node.
43       Each node is assigned a unit address which is determined by  the  value
44       of  the  unit-address   property.  This  property is only applicable to
45       children of the IB parent and is required. See driver.conf(4) for  fur‐
46       ther details on configuration file syntax.

EXAMPLES

49       Example 1: Sample configuration file
50
51
52       Here is a configuration file called ibgen.conf for an IB  device driver
53       that implements a generic IB driver. This file creates  a  node  called
54       ibgen.
