Abstract

A technique for managing physical and virtual resources within a multifunction chipset includes a resource manager in the form of a software agent that maintains a global resource namespace built from a list of parent-child object relationships. In general, the parent objects represent resource producers while the child objects represent resource consumers. By examining the various parent-child relationships in the global resource namespace, the resource manager can determine how the various system resources are being consumed. A rebalancing process is provided to rebalance resources with the global resource namespace in response to system events that cause a change in available system resources.

Claims

1. A method, comprising:

maintaining a global resource namespace including a list of a plurality child and parent resource objects and a representation of the relationships among the child and parent resource objects; and

rebalancing the plurality of resource objects.

2. The method of claim 1, wherein rebalancing the plurality of resource objects includes recalculating available resources.

3. The method of claim 2, wherein rebalancing the plurality of resource objects includes determining whether the available resources are less than currently consumed resources.

4. The method of claim 3, wherein rebalancing the plurality of resource objects includes allocating a temporary namespace if the available resources are less than the currently consumed resources.

5. The method of claim 4, wherein rebalancing the plurality of resource objects includes for each child resource object determining whether the child resource object has an owner.

6. The method of claim 5, wherein rebalancing the plurality of resource objects includes performing an attachment routine for each child object that is found to have an owner.

7. The method of claim 6, wherein rebalancing the plurality of resource objects includes destroying the old global resource namespace.

8. The method of claim 7, wherein rebalancing the plurality of resource objects includes renaming the temporary namespace to become a new global resource namespace.

9. A machine-readable medium having stored thereon instructions which, when executed by a computer system, causes the computer system to perform a method comprising:

maintaining a global resource namespace including a list of a plurality child and parent resource objects and a representation of the relationships among the child and parent resource objects; and

rebalancing the plurality of resource objects.

10. The machine readable medium of claim 9, wherein rebalancing the plurality of resource objects includes recalculating available resources.

11. The machine readable medium of claim 10, wherein rebalancing the plurality of resource objects includes determining whether the available resources are less than currently consumed resources.

12. The machine readable medium of claim 11, wherein rebalancing the plurality of resource objects includes allocating a temporary namespace if the available resources are less than the currently consumed resources.

13. The machine readable medium of claim 12, wherein rebalancing the plurality of resource objects includes for each child resource object determining whether the child resource object has an owner.

14. The machine readable medium of claim 13, wherein rebalancing the plurality of resource objects includes performing an attachment routine for each child object that is found to have an owner.

15. The machine readable medium of claim 14, wherein rebalancing the plurality of resource objects includes destroying the global resource namespace.

16. The machine readable medium of claim 15, wherein rebalancing the plurality of resource objects includes renaming the temporary namespace to become a new global resource namespace.
