Table 3-53 Parameters for PVBusMapper

Name Type Default value Description
pvbusmodifier.handling_of_dvm_messages_from_downstream string "forward" What to do with DVM (Distributed Virtual Memory) messages received from downstream. The options are to 'forward' them upstream unaltered, to 'terminate' them, or to 'handle' them locally and get called through handleDownstreamDVMMessage()
pvbusmodifier.handling_of_dvm_messages_from_upstream string "forward" What to do with DVM (Distributed Virtual Memory) messages received from upstream. The options are to 'forward' them downstream unaltered, to 'terminate' them, or to 'handle' them locally and get called through handleUpstreamDVMMessage()
pvbusmodifier.handling_of_upstream_snoop_requests string "forward" What to do with snoop requests from downstream. The options are to 'forward', 'terminate' or 'handle'. NOTE that currently the snoop request addresses are _not_ translated and so if your device alters the address translation then you will almost certainly want to 'terminate'.
