Most VME devices require hardware configuration files to inform the system that the device hardware may be present. The configuration file must specify the device addresses on the VMEbus and any interrupt capabilities that the device has.
Configuration files for VMEbus devices should identify the parent bus driver implicitly using the class keyword and specifying class "vme." This removes the dependency on the name of the particular bus driver involved, since the driver may be named differently on different platforms. See driver.conf(4) and vme(4) for further details.
