1. A system comprising: a platform domain implementing address-indexed operations, the platform domain comprising: a platform interconnect to process address-indexed platform transactions; and a trace monitor to generate a debug trace stream from platform transactions of the platform interconnect based on platform context information of the platform transactions, the platform context information comprising at least one of an address, an attribute, or a data; and an application domain implementing application context-oriented operations, the application domain comprising: a processing component coupled to the platform interconnect; and a queue manager to queue descriptors for corresponding data frames to be processed by the application domain, each descriptor comprising application context information for the corresponding data frame, the application context information including application-specific debug information; and the processing component to process a selected data frame by: accessing, from the queue manager, a descriptor associated with the selected data frame; translating a first application-specific debug information of the descriptor to a corresponding first platform attribute value; and providing a first platform transaction to the platform interconnect for processing in the platform domain, the first platform transaction comprising the first platform attribute value in an attribute field.
