In some embodiments, the invention involves a system and method relating to managing power utilization in systems having multiple processing elements. In at least one embodiment, the present invention is intended to control the sleeping/wakefulness of processing elements, as necessary, to maintain a preferred level of power utilization in the platform. Activity is routed to sequestered processing elements instead of sleeping processing elements to save power.

A computer system is partitioned during a pre-boot phase of the computer system between a first partition and a second partition, wherein the first partition to include a first processing unit and the second partition to include a second processing unit. An Input/Output (I/O) operating system is booted on the first partition. A general purpose operating system is booted on the second partition. Network transactions are issued by the general purpose operating system to be performed by the I/O operating system. The network transactions are performed by the I/O operating system.

Enhancing locality in a security co-processor module of a computing system may be achieved by including one or more additional attributes such as geographic location, trusted time, a hardware vendor string, and one or more environmental factors into an access control space for machine mode measurement of a computing system.

A method and system for handling a management interrupt, such as a system management interrupt (SMI) and/or a platform management interrupt (PMI), includes allocating two or more processor cores from a plurality of processor cores to form a group of management interrupt handling processor cores. Generated management interrupts are directed to this first group of processor cores and not to remaining processor cores, which forma second group. At least one of the processor cores in the first group handles the management interrupt without disrupting the current operation of the processor cores in the second group.

Methods and apparatuses for re-instantiating a firmware environment that includes one or more firmware functions available at pre-boot time when transitioning the computing device from a wake state to a sleep state. A network event received by the computing device while in a sleep state may be handled by the firmware environment independent of the operating system and without returning the entire computing device to the wake state.

A method and apparatus is described herein for performing parallel memory migration, as well as execution of management tasks over a plurality of management window. Handlers are dispatched to multiple resources, such as cores or threads, to determine a proper memory migration handler. Each resource, during a management mode, executes a designated memory migration handler or an instance of a memory migration handler to perform a portion of a memory migration task in parallel. A task data structure is capable of supporting tracking of portions of memory migrated. In addition the task data structure is potentially also capable of tracking management tasks through plurality of management windows to support servicing of management tasks through multiple management windows.

In some embodiments, the invention involves reducing the time required for a platform to boot to its target application/operating-system using parallelization of firmware image content decompression and loading. An embodiment dispatches alternate processing agents as a means to intelligently assist in off-loading some of the initialization tasks so that the main processor may share the burden of boot tasks. In at least one embodiment, it is intended to build firmware images that facilitate parallelization, utilizing co-processing agents that can split these transactions across various processing agents. Other embodiments are described and claimed.
摘要:
A system and method for maintaining computer platform components in an optimal state. The method determines whether a platform includes an out-of-band processor, and if the platform includes an out-of-band processor, then the out-of-band processor is enabled to passively or proactively obtain firmware and/or option ROM (Read Only Memory) updates for add-in cards on the platform. Once the out-of-band processor has obtained the updates for the add-in cards on the platform, the out-of-band processor will place the updates in a platform mailbox and send an interrupt to the in-band processor indicating that firmware and/or option ROM updates are available in a platform mailbox. The in-band processor will launch the firmware and/or option ROM updates on the platform.
摘要:
An embodiment of the present invention is a system and method relating to shrinking, or optimizing, executable images resulting is a savings of storage space. In at least one embodiment, the present invention removes unnecessary fields, or information, from an executable image header before storing the image on a flash for a target platform. The removal of information that is irrelevant to the target platform allows the executable to take up less space on the flash memory. When loaded, the image is interpreted based on the optimized header information. In an embodiment, the image may be further compressed by known methods, to save additional space. Other embodiments are described and claimed.

In some embodiments, the invention involves system and method for resuming from sleep mode using protected storage accessible to an embedded controller. The boot script information is stored in memory that is available only to the embedded controller. Neither the firmware nor OS have access to the boot script. Upon a wake event, the embedded controller either plays the boot script itself, or sends the information to firmware for processing. Other embodiments are described and claimed.
