Abstract: Provided are a method, system and program for effecting an operating system mode change from one mode to another. In one embodiment, the operating system in one mode is placed in a sleep state in which volatile memory remains active. In booting an operating system from the sleep state, a flag may be detected indicating an operating system mode transfer request. In response, contents of a selected range of volatile memory allocated to the first operating system mode may be swapped with the contents of a selected range of a reserve portion of volatile memory allocated to the second operating system mode. Booting of an operating system in the second mode may be completed using the swapped contents of the volatile memory. Additional embodiments are described and claimed.

Abstract: Embodiments of the present invention provide for implementation of data transfers in an efficient manner. The 48-bit LBA mechanism requires two sets of I/O writes to IDE registers on primary channel or secondary channel. The two sets of I/O writes to the primary or secondary channel registers are performed by setting a status register to a first or second state appropriately depending on the data. Embodiments of the present invention provide a single set of writes to I/O registers when the size of the data transfer is equal to or below a threshold value.

Abstract: Embodiments of the present invention provide for generation of SMI from ACPI ASL control method code to execute complex tasks including, but not limited to, transferring or searching through large amounts of data dynamically. Instead of executing certain tasks using limited ASL functionality, an SMI is generated in an ASL code execution path to enable usage of a CPU instruction set accessible to the SMM handler. In particular, an ACPI operation region is defined for an I/O address location capable of triggering an SMI. An ACPI control method accesses the SMI generation I/O address location to generate an SMI during ASL code execution when a predefined complex task is encountered, thus enabling the SMI handler code to advantageously execute the complex task.

Abstract: A system and method to determine a presence of devices coupled to one a more peripheral buses in a system, and dynamically reducing power consumption of a subset of the devices that are present, based on correlating application/device association and a predetermined power source budget. In one embodiment, the reducing of the power consumption is performed dynamically by having an agent reduce the power limit in a device register(s) corresponding to the subset of devices. Furthermore, in one embodiment, the power resource budget is based at least in part on a user-selected power/performance level.

Abstract: A device to control memory bandwidth including a processing unit and a memory connected to the processing unit, the memory having a memory controller driver to issue at least one command based on a memory bandwidth requirement of another driver process. A memory controller to direct data to and from the memory. An active cooling device is connected to the processing unit and a thermal sensor.

Abstract: An ACPI (Non-Volatile Sleeping) NVS memory region is allocated and defined so that a system BIOS can allocate a placeholder for the different parameters that are passed from the ACPI ASL code to the system management mode (SMM) handler for execution of real mode calls. The different parameters will be updated by runtime ACPI ASL code depending on what needs to be passed to the SMM handler. The SMM handler invokes appropriate calls based on retrieving of different parameters in the ACPI NVS memory region that have been passed from the ACPI ASL code.
