Method and apparatus for recording and monitoring bus activity in a multi-processor environment

摘要

A method and apparatus to facilitate a history trace of system bus activity in a Symmetric Multi-Processor (SMP) environment. A dynamic scan capability is provided to User ( 516 ) via Computer ( 504 ) that allows dynamic configuration of History Control Register ( 518 ), thus providing a maskable history stack of system bus activity to be obtained from History Memory ( 508 ) for subsequent analysis.
