ing will be available in a later release). If there is no device node, then
the user can add a device node by clicking the Add Device button.
 MBAR: The 64‐bit main address bar (i.e. BAR1:BAR0). Without this value decod‐
ing cannot be done. It should be in "0x" hex format.
 Queues: Under this node the user can add more missing nodes to decode the
current trace. Click the Add Queue or Delete Queue button to add or

information is present in the trace then it is not editable, otherwise it can be edited.
Decoding is done only when configuration space and administration information is
available.
