System and method for reducing memory overhead of a page table in a dynamic logical partitioning environment

A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• allocate portions of the main memory to a plurality of logical partitions in the data processing system;
• generate a single shared page table having a plurality of page table entries, wherein the plurality of page table entries comprises page table entries for accessing each of the portions of the main memory allocated to each of the logical partitions in the plurality of logical partitions;
• and
• utilize the single shared page table to access the portions of the main memory.

An apparatus, comprising:

• a processor;
• and
• a main memory coupled to the processor, wherein the main memory comprises instructions which, when executed by the processor, cause the processor to:
• allocate portions of the main memory to a plurality of logical partitions in the data processing system;
• generate a single shared page table having a plurality of page table entries, wherein the plurality of page table entries comprises page table entries for accessing each of the portions of the main memory allocated to each of the logical partitions in the plurality of logical partitions;
• and
• utilize the single shared page table to access the portions of the main memory.
