Abstract In one embodiment, a processor comprises a fabric interconnect to couple a first cache agent to at least one of a memory controller or an input/output (I/O) controller; and a first cache agent comprising a cache controller coupled to a cache; and a trace and capture engine to periodically capture a snapshot of state information associated with the first cache agent; trace events to occur at the first cache agent in between captured snapshots; and send the captured snapshots and traced events via the fabric interconnect to the memory controller or I/O controller for storage at a system memory or storage device.
