摘要： A network interface that connects a computing device to a network may be configured to process incoming packets and determine an action to take with respect to each packet, thus decreasing processing demands on a processor of the computing device. The action may be indicating the packet to an operating system of the computing device immediately, storing the packet in a queue of one or more queues or discarding the packet. When the processor is interrupted, multiple packets aggregated on the network interface may be indicated to the operating system all at once to increase the device's power efficiency. Hardware of the network interface may be programmed to process the packets using filter criteria specified by the operating system based on information gathered by the operating system, such as firewall rules.

摘要： A method and apparatus for correlating the identities of hardware devices, such as processors or memory controllers, between a local operating system and a global management entity is described. In an embodiment a fault message including a local identifier of a faulting device is received from an operating system. A global identifier of the faulting device is determined that is different from the local identifier. An appropriate replacement device is then selected based on the global identifier of the faulting device, and the selected replacement device is mapped to the faulting device.

摘要： A method and apparatus for transparently replacing a processor, that receives interrupts in a partitioned computing device, with a replacement processor, is disclosed. The method comprises directing the interrupts to an unchangeable identifier mapped to the processor's identifier and replacing the processor with the replacement processor. An intermediary, such as an I/O APIC, is used for storing the unchangeable identifier. The mapping may use logical mode delivery, physical mode delivery, or interrupt mapping.

摘要： Techniques and apparatuses for providing power-aware thread scheduling and dynamic use of processors are disclosed. In some aspects, a multi-core system is monitored to determine core activity. The core activity may be compared to a power policy that balances a power savings plan with a performance plan. One or more of the cores may be parked in response to the comparison to reduce power consumption by the multi-core system. In additional aspects, the power-aware scheduling may be performed during a predetermined interval to dynamically park or unpark cores. Further aspects include adjusting the power state of unparked cores in response to the comparison of the core activity and power policy.

摘要： Methods, systems, and computer program products for remotely monitoring diverse computer systems in a similar manner over an out-of-band communication channel. Remote monitoring ordinarily is performed over an in-band communication channel. However, hardware and/or software problems may make the in-band communication channel unavailable for a time. While the in-band communication channel is unavailable, the management computer receives status information over the out-of-band communication channel. Based on received status information, the management computer identifies actions to take, such as controlling processes or otherwise configuring the remote computer system, and communicates the actions to the remote computer system over the out-of-band communication channel. The management computer is capable of communicating with any of several diverse computers and exchanges data in a format that is independent of any particular computer system. The format also separates status information from placement information used to display the status information, and may conform to an XML schema.

摘要： A system and method for facilitating BIOS integrated encryption is provided. An interface is defined between the operating system and the BIOS. The operating system employs this interface to provide BIOS code information to facilitate decryption of data that is encrypted on the system. In the pre-operating system boot phase, the BIOS employs the decryption information provided from this interface in order to decrypt the data. The decrypted information can be employed to facilitate secure rebooting of a computer system from hibernate mode and/or secure access to device(s).

摘要： Transitioning to a suspend to RAM sleeping state while also protecting against power losses while sleeping is provided. System state context data is saved to non-volatile storage and components in the computer system prepare to transition to a suspend to disc sleeping. A transition to the suspend to RAM sleeping state is then effected. Alternatively, after the system context is saved and the components are prepared to transition, the system may wake to a working state. The components may be directed to prepare for transitioning to a suspend to RAM sleeping state, and then the BIOS may be directed to execute the transition. In either embodiment, if power to the system is lost while the system is in the suspend to RAM system state, then the system may resume to a working state by reading the context file stored to non-volatile storage.
