Abstract

A controller may include circuitry to execute a management policy associated with a computer accessible resource based on a process identifier. The process identifier may be associated with a thread initiated by a set of instructions executed by a processor resource. The controller may be operatively coupled to a register to contain a process identifier.

Claims

1. A resource management apparatus comprising:

a register to contain a process identifier associated with a thread initiated by a set of instructions executed by a processor resource; and

a controller operatively coupled to the register, the controller including a circuitry to execute a management policy that is used to manage an event associated with a computer accessible resource based on the process identifier.

2. The resource management apparatus of claim 1, wherein the management policy includes at least one of an allocation policy to allocate a portion of the computer accessible resource, an eviction policy to remove a set of data from the computer accessible resource, a replacement policy to refresh the set of data contained in the computer accessible resource, and a directory policy to order the directory structure of the computer accessible resource.

3. The resource management apparatus of claim 1, wherein the controller is one of a core controller, cache controller, a memory management unit, and an input-output management unit.

4. The resource management apparatus of claim 1, comprising a second register coupled to the controller, the second register to contain an entry of a table, the circuitry to compare the register to the second register.

5. The resource management apparatus of claim 4, comprising a translation lookaside buffer, the translation lookaside buffer operatively coupled to the second register and associated with the table.

6. A resource management system comprising:

a computer accessible resource;

a controller associated with the computer accessible resource, the controller having circuitry to execute a management policy based on a process identifier associated with a thread;

and a processor resource operatively coupled to the controller and a computer readable storage medium, wherein the computer readable storage medium contains a set of instructions, the processor resource to carry out the set of instructions to;

cause the controller to execute the management policy; and

manage the computer accessible resource based on the management policy and the process identifier.

7. The resource management system of claim 6, wherein the management policy defines an event priority associated with the computer accessible resource based on the process identifier.

8. The resource management system of claim 6, further comprising a management engine to provide a management policy to the controller, the controller to at least one of:

allocate a portion of the computer accessible resource based on the process identifier;

remove a set of data from the computer accessible resource based on the process identifier; and

maintain an order of the set of data of the computer accessible resource based on the process identifier.

9. The resource management system of claim 6, comprising an operating system engine, the operating system engine to:

execute a management request associated with a memory address; and

create a page table entry having a request identifier associated with the management request.

10. The resource management system of claim 8, comprising a translation lookaside buffer coupled to the controller, the translation lookaside buffer to compare the page table entry with the process identifier.

11. A method for managing a computer accessible resource comprising:

upon execution of a management request to the computer accessible resource;

comparing a request identifier to a process identifier; and

managing the computer accessible resource according to a management policy based on the process identifier.

12. The method of claim 11, comprising

upon creation of a thread:

setting the request identifier in a page table entry, the page table entry associated with the thread; and

setting the process identifier in a register.

13. The method of claim 11, comprising determining event priority associated with the computer accessible resource based on the process identifier.

14. The method of claim 11, wherein the management policy includes at least one of:

allocating a portion of the computer accessible resource;

evicting an entry of the computer accessible resource;

replacing the entry of the computer accessible resource; and

adjusting a cache directory.

15. The method of claim 14, comprising:

allocating a portion of the computer accessible resource to the process identifier; and

intercepting an interrupt request to access the portion of the computer accessible resource.
