Abstract
An information carrier medium containing software that, when executed by a processor, causes the processor to receive status information from circuit logic that collects the status information from caches associated with different processor cores. The software also causes the processor to provide the information to a user of the software. The status information indicates whether one of the caches comprises an entry associated with a virtual address.
Claims13
An information carrier medium containing software that, when executed by a processor, causes the processor to:
- receive status information from circuit logic that collects the status information from caches associated with different processor cores;
- and
- provide said information to a user of said software;
- wherein the status information indicates whether one of said caches comprises an entry associated with a virtual address.
A system, comprising:
- a cache subsystem configured according to a hierarchy comprising a plurality of cache levels;
- and
- a control logic coupled to said cache subsystem, said control logic adapted to collect status information from caches levels associated with different processor cores and to provide said status information to a destination;
- wherein the status information indicates whether one of said cache levels comprises an entry associated with a virtual address.
A method, comprising:
- collecting status information from storages associated with a plurality of processor cores;
- transferring said status information from said storages to a control logic coupled to the storages;
- and
- providing said status information to a user;
- wherein the status information indicates whether one of said storages comprises an entry associated with a virtual address.
