  • Qualification of event detection by thread ID and thread privilege level
    Patent number: 7448025
    Abstract: A method and apparatus for monitoring the performance characteristics of a multithreaded processor executing instructions from two or more threads simultaneously. Event detectors detect the occurrence of specific processor events during the execution of instructions from threads of a multithreaded processor. Specialized event select control registers are programmed to control the selection, masking and qualifying of events to be monitored. Events are qualified according to their thread ID and thread current privilege level (CPL). Each event that is qualified is counted by one of several programmable event counters that keep track of all processor events being monitored. The contents of the event counters can then be accessed and sampled via a program instruction.

  • Method and apparatus to monitor the performance of a processor
    Patent number: 6772322
    Abstract: A method and apparatus to monitor the performance of a processor. A performance specifier specifies a performance data corresponding to the performance. The performance data includes an event and an instruction causing the event. A tag generator is coupled to the performance specifier to generate a performance tag associated with the instruction. The performance tag is stored in a storage. A retirement performance monitor is coupled to the storage to extract the performance tag when the instruction is retired.
