Abstract
A system employs a white list of authorized transactions to control access to system registers. In an embodiment, the white list is loaded into filter registers during system boot. Routing logic monitors a logical interconnect fabric of the system for register access requests. The routing logic parses source, destination information from a request to index the white list. If the white list includes an entry corresponding to the processing entity indicated in the source information and the register indicated in the destination information, the routing logic will permit the requested access.
