| 摘要 |
A method and apparatus are described for managing a plurality of performance monitoring resources residing in a plurality of cores of a processor. A plurality of resource queues are maintained. Each resource queue corresponds to a particular one of the performance monitoring resources, and detects conflicts in use of the particular performance monitoring resource by multiple users. The detected conflicts associated with the particular performance monitoring resource are then resolved. A dynamic resource scheduler is used to resolve the detected conflicts, and is driven by an advanced programmable interrupt controller (APIC) timer residing in a particular core of the processor to provide each item, in an items list of a resource queue associated with the particular performance monitoring resource, an equal opportunity to use the particular performance monitoring resource for a predetermined period of time.
