Abstract

A system and method for achieving one or more protected regions within a computer system having multiple partitions are disclosed. In at least some embodiments, the system includes an intermediary device for use within the computer system having the multiple partitions. The intermediary device includes a fabric device, and a first firewall device capable of limiting communication of a signal based upon at least one of a source of the signal and an intended destination of the signal, the first firewall device being at least indirectly coupled to the fabric device. The intermediary device further includes a first conversion device that is one of integrated with the first firewall device and distinct from the first firewall device, and that is capable of converting between a processor address and a fabric address for use by the fabric device. In some embodiments, the various devices each include Control and Status Registers (CSRs).
