Apparatus and method for role-based register protection. For example, one embodiment of an apparatus comprises: one or more processor cores to execute instructions and process data, the one or more processor cores to execute one or more security instructions to protect a virtual machine or trusted application from a virtual machine monitor (VMM) or operating system (OS); an interconnect fabric to couple the one or more processor cores to a device; and security hardware logic to determine whether to allow a read or write transaction directed to a protected register to proceed over the interconnect fabric, the security hardware logic to evaluate one or more security attributes associated with an initiator of the transaction to make the determination.

An interface for coupling an agent to a fabric supports a load/store interconnect protocol and includes a header channel implemented on a first subset of a plurality of physical lanes, the first subset of lanes including first lanes to carry a header of a packet based on the interconnect protocol and second lanes to carry metadata for the header. The interface additionally includes a data channel implemented on a separate second subset of the plurality of physical lanes, the second subset of lanes including third lanes to carry a payload of the packet and fourth lanes to carry metadata for the payload.

Streaming fabric interface

An end of a queue or a page-crossing within a queue is detected. A virtual memory address for the head of the queue or for the next queue page is pre-translated into a physical memory address while the last entry in the queue or in the current queue page is being serviced.
