Conditional page fault control for page residency

A method of processing a non-resident page comprising:

• attempting to access the non-resident page, an address for the non-resident page pointing to a memory page containing default values;
• returning an indication that a memory read did not translate and returning the default values when the access of the non-resident page is a read and the non-resident page should not cause a page fault;
• and
• discontinuing a write when the access of the non-resident page is a write and the non-resident page should not cause a page fault.

An apparatus for processing a non-resident page comprising:

• a processor configured to:
• attempt to access the non-resident page, an address for the non-resident page pointing to a memory page containing default values;
• determine that the non-resident page should not cause a page fault based on checking an indicator that indicates that the non-resident page should not generate a page fault;
• and
• return an indication that a memory read did not translate and return the default values when the access of the non-resident page is a read and the non-resident page should not cause a page fault.

• means for determining that the non-resident page should not cause a page fault based on the means checking an indicator that indicates that the non-resident page should not generate a page fault;
• and
• means for returning a default value when the access of the non-resident page is a read and the non-resident page should not cause a page fault.

An apparatus for informing a client that a page is non-resident page comprising:

• means for accessing a non-resident page, an address for the non-resident page pointing to a memory page containing default values;
• means for returning an indication that a memory read did not translate and means for returning the default values when the access of the non-resident page is a read and the non-resident page should not cause a page fault;
• and
• means for discontinuing a write when the access of the non-resident page is a write and the non-resident page should not cause a page fault.

A non-transitory computer readable storage medium storing instructions that upon execution by one or more processors cause the one or more processors to:

• attempt to access a non-resident page, an address for the non-resident page pointing to a memory page containing default values;
• determine that the non-resident page should not cause a page fault based on checking an indicator that indicates that the non-resident page should not generate a page fault;
• and
• return an indication that a memory read did not translate and return the default value when the access of the non-resident page is a read and the non-resident page should not cause a page fault.
