| 发明名称 | Paravirtualized migration counter | ||
| 摘要 | An application associated with a processor reads a first value of a counter and a second value of the counter. The counter is indicative of a migration status of the application with respect to the processor. Responsive to determining that the first value of the counter does not equal the second value of the counter, the application ascertains whether a value of a hardware parameter associated with the processor has changed during a time interval. The migration status indicates a count of the number of times the application has migrated from one processor to another processor. The application determines the validity of a value of a performance monitoring unit derived from the hardware parameter in view of the application ascertaining whether the value of the hardware parameter has changed during the time interval. | ||

| 主权项 | 1. A method, comprising: determining, by a processing device, a first value of a counter and a second value of the counter, wherein the counter is indicative of a migration status of an application with respect to the processing device; responsive to determining that the first value of the counter does not equal the second value of the counter, ascertaining whether a value of a hardware parameter associated with the processing device has changed during a time interval; and determining, by the processing device, validity of a value of a performance monitoring unit derived from the hardware parameter in view of said ascertaining. | ||
