Embodiments include methods, apparatus, and systems for virtual address hashing. One embodiment evenly distributes page-table entries throughout a hash table so applications do not generate a same hash index for mapping virtual addresses to physical addresses.

Virtual address hashing

A system and method for loading an Advanced Configuration and Power Interface (ACPI) original equipment manufacturer (OEM) description table in a computer platform employing an ACPI-compatible implementation is disclosed. In one embodiment of the system, a storage structure is operably associated with the computer platform and contains a copy of an ACPI OEM description table in a packed form. An acquirer is operable to search the storage structure fop the ACPI OEM description table and call a swapper to complete the loading of the ACPI OEM description table by issuing a signature search request.

Computer data is transferred from a packed to an unpacked data structure in a computer that enforces aligned memory access and for which the associated compiler lacks a compile-time directive to pack data structures. In an exemplary embodiment, the invention is employed in the pre-processing of Advanced Configuration and Power Interface (ACPI) tables stored in little-endian format for use by a big-endian operating system.

Method for transferring a packed data structure to an unpacked data structure by copying the packed data using pointer

The bits comprising a computer data structure are reversed rapidly and efficiently using a combination of data partitioning and table look ups. In an exemplary embodiment, the invention is employed in the pre-processing of Advanced Configuration and Power Interface (ACPI) tables stored in little-endian format for use by a big-endian operating system.
