cpu: Add support for scheduling multiple inst/load stop events
Review Request #1891 - Created June 2, 2013 and submitted
Changeset 9741:a2b7eb136cea --------------------------- cpu: Add support for scheduling multiple inst/load stop events Currently, the only way to get a CPU to stop after a fixed number of instructions/loads is to set a property on the CPU that causes a SimLoopExitEvent to be scheduled when the CPU is constructed. This is clearly not ideal in cases where the simulation script wants the CPU to stop at multiple instruction counts (e.g., SimPoint generation). This changeset adds the methods scheduleInstStop() and scheduleLoadStop() to the BaseCPU. These methods are exported to Python and are designed to be used from the simulation script. By using these methods instead of the old properties, a simulation script can schedule a stop at any point during simulation or schedule multiple stops. The number of instructions specified when scheduling a stop is relative to the current point of execution.
