SERVICE_PROVIDER.CONF(5) File Formats and Configurations

NAME

service_provider.conf - service provider configuration file

SYNOPSIS

service_provider.conf

DESCRIPTION

service_provider.conf contains information about the device type that the
service provider supports. This information includes the pathname of the
service provider library, the library version and other library
characteristics that are required by the system administrative command,
datadm(8). datadm(8) puts this information in the DAT static register
file, dat.conf(5).

The datadm program enumerates each device entry into a list of interface
adapters, that is, interfaces to external network that are available to
uDAPL consumers. This new list of interface adapters is appended to other
service providers' information in the DAT static registry, dat.conf. You
can do this if you invoke the datadm program with the -a option and the
pathname of the service_provider.conf file.

Each entry in the service_provider.conf is a single line of 7 fields.

The following shows the order of the fields in a service_provider.conf
entry:

"driver_name" "API_version" "threadsafe_library | \
nonthreadsafe_library"\
"default_version | nondefault_version" \
"service_provider_library_pathname"\
"service_provider_version" "service_provider_instance_data"\

The fields are defined as follows:

driver_name

Specifies a driver name in the format of driver_name=value pair, for
example, driver_name=tavor.

API_version

Specifies the API version of the service provider library: For
example, "u"major.minor is u1.2.

threadsafe_library | nonthreadsafe_library

Specifies a threadsafe or non-threadsafe library.

default_version | nondefault_version

Specifies a default or non-default version of a library. A service
provider can offer several versions of the library. If so, one
version is designated as default with the rest as nondefault.

service_provider_library_pathname

Specifies the pathname of the library image.

service_provider_version

Specifies the version of the service provider. By convention, specify
the company stock symbol as the service provider, followed by major
and minor version numbers, for example, SUNW1.0.

service_provider_instance_data

Specifies the service provider instance data.

EXAMPLES

Example 1: Using a Logical Device Name

The following example service_provider.conf entry uses a logical device
name:

#
# Sample service_provider.conf entry showing an uDAPL 1.2 service
# provider, udapl_tavor.so.1 supporting a device with a driver named
# tavor
driver_name=tavor u1.2 nonthreadsafe default udapl_tavor.so.1 \
SUNW.1.0 ""

Example 2: Using a Physical Device Name

The following example service_provider.conf uses a physical device name:

#
# Sample service_provider.conf entry showing an uDAPL 1.2
# service provider, udapl_tavor.so.1 supporting a device named
# pci15b3,5a44 that can be located under /devices
#
pci15b3,5a44 u1.2 nonthreadsafe default \
/usr/lib/tavor/udapl_tavor.so.1 SUNWudaplt1.0 ""
