Transaction mappers, methods and systems are provided. An example transaction mapper includes a table that associates virtual identification values with bus-device-function (BDF) values; and a firewall that receives an input-output request including a first virtual identification value of the virtual identification values, the first virtual identification value being associated with a function of an external peripheral, generates a first BDF value and a first traffic class value based on the table and the first virtual identification value, determine whether the first virtual identification value satisfies a threshold range, and determine whether to forward the input-output request to an external host device based on whether the first virtual identification value satisfies the threshold range.

Multi-peripheral and/or multi-function export

A system is provided. In some examples, the system includes a first peripheral circuit and a memory management circuit coupled to the first peripheral circuit. The memory management circuit comprises a first table that associates virtual identification values with address space select values. The system also includes a transaction mapper circuit coupled to the memory management circuit. The transaction mapper circuit comprises a second table that associates virtual identification values with bus-device-function values.
