ABSTRACT:
What is provided is a load page table entry address function defined for a machine architecture of a computer system. In one embodiment, a machine instruction is obtained which contains an opcode indicating that a load page table entry address function is to be performed. The machine instruction contains an M field, a first field identifying a first general register, and a second field identifying a second general register. Based on the contents of the M field, an initial origin address of a hierarchy of address translation tables having at least one segment table is obtained. Based on the obtained initial origin address, dynamic address translation is performed until a page table entry is obtained. The page table entry address is saved in the identified first general register.
