Packet probe point.
This probe point provides a unified interface for components that want to instrument Packets in the memory system. Components should when possible adhere to the following naming scheme:
PktRequest: Requests sent out on the memory side of a normal components and incoming requests for memories. Packets should not be duplicated (i.e., a packet should only appear once irrespective of the receiving end requesting a retry).
PktResponse: Response received from the memory side of a normal component or a response being sent out from a memory.
PktRequestCPU: Incoming, accepted, memory request on the CPU side of a two-sided component. This probe point is primarily intended for components that cache or forward requests (e.g., caches and XBars), single-sided components should use PktRequest instead. The probe point should only be called when a packet is accepted.
PktResponseCPU: Outgoing response memory request on the CPU side of a two-sided component. This probe point is primarily intended for components that cache or forward requests (e.g., caches and XBars), single-sided components should use PktRequest instead.
