摘要
A system and method for profiling runtime system events of a computer system may include associating a data source type with detected system events. The system events may be detected dependent on information included in a reply message received by a processor in response to a data request or other transaction request message. The reply message may include information characterizing a source type of a source of data included in the reply message. The source type information may indicate that the source is remote or local; that it is a shared or a private storage location; that the data is supplied via a cache-to-cache transfer; or that the data is sourced from a coherency domain other than that of the requesting process. Instructions, events, messages, and replies may be sampled, and extended address information corresponding to the samples may be stored in an event set database for performance analysis.
