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

Embodiments of the present invention pertain to methods and systems are described for switching root cells for a computer system without requiring the computer system to be re-booted. In one embodiment, objects are used to represent fixed registers associated with a first cell and a second cell of the computer system. In response to detecting that the second cell should be used instead of the first cell as a root cell for the computer system, the objects are used to communicate information between firmware and an operating system associated with the computer system, wherein the information describes the fixed registers associated with the second cell.

A system and method for constructing a user application's Advanced Configuration and Power Interface (ACPI) namespace in a computer platform employing an ACPI-compatible implementation is disclosed. A traversing function is operable to traverse a kernel ACPI namespace nodal tree and provide the name of the node of the tree to the user application's ACPI namespace. The traversing function may withhold a copy of a particular node if that node is a control method object not included in a list of safe control methods. Another embodiment provides a scheme for assisting a user application's access to a control method object.

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.
