Abstract:
A method, performed by a data processing system having a virtual memory system, to omnibus wire a page in a memory of the data processing system, comprising:following a first group of pointers that refer to the omnibus wired page upwards in the virtual memory system to ensure that all elements referenced by the first group of pointers are also omnibus wired, where omnibus wiring the page guarantees that the page is present in memory, that all mapping tables referencing the omnibus wired page are also present in memory, and that the omnibus wired page can be referenced via the mapping tables; andfollowing a second group of pointers that also refer to the omnibus wired page, where the second group of pointers are part of an uplevel reference, upwards in the virtual memory system to ensure that all memory elements referenced by the second group of pointers are also omnibus wired.
