A method for usurping control of a computer system from an operating system using a mechanism otherwise used to enable the entry of the computer system into a lower power state.

Method for firmware control invocation from power management

An apparatus and method for enumeration of processors during hot-plug of a compute node are described. The method includes the enumeration, in response to a hot-plug reset, of one or more processors. The enumeration is provided to a system architecture operating system in which a compute node is hot-plugged. Once enumeration is complete, the compute node is started in response to an operating system activation request. Accordingly, once device enumeration, as well as resource enumeration are complete, the one or more processors of the processor memory node are activated, such that the operating system may begin utilizing the processors of the hot-plugged compute node.

Apparatus and method for enumeration of processors during hot-plug of a compute node

Hot plug modules comprising processors, memory, and/or I/O hubs may be added to and removed from a running computing device without rebooting the running computing device. The hot plug modules and computing device comprise hot plug interfaces that support hot plug addition and hot plug removal of the hot plug modules.

Hot plug interface control method and apparatus

A method and an apparatus for managing power consumption of a server have been disclosed. In one embodiment, the method includes allowing a user to set a power management policy on a server, monitoring power consumption of a plurality of blades in the server, and automatically managing power consumption of the server in response to the power consumption of the plurality of blades based on the power management policy set by the user. Other embodiments have been claimed and described.

Error detection methods, systems and medium are provided. The error detection method may comprise processing error conditions associated with transactions in a manner that may enable error source identification. The system may comprise a plurality of nodes of components. The nodes may include storage elements to record an error condition indicative of whether a component provided an indication of detecting an error in response to processing the transaction.

Error method, system and medium

A system that may optionally be partitioned into multiple domains is disclosed. Each domain is capable of independently powering on, executing a firmware program, and loading an operating system, including a legacy operating system, as well as running an application program that is distinct from programs running on another domain. Interrupts, including boot interrupts, reset handlers, and inter-chassis communications are initialized differently, depending on whether the system is to be partitioned or not. The cost of redundant hardware and/or firmware is substantially avoided, yet the system fully supports multiple domains.

Partitionable multiprocessor system having programmable interrupt controllers

A computing device maintains coherency while supporting addition and removal of memory caching agents without rebooting the computing device.

Hot plug cache coherent interface method and apparatus

One embodiment of the invention provides a firmware architecture which splits firmware modules to support safe updates of specific modules as well as supporting multiple different processors. A firmware image is partitioned into several different binaries based on their update requirements and processor/platform dependence. A firmware interface table enables safe updates by enabling the option of redundant copies of specific modules as well as supporting systems with different and/or multiple processor types, mixed processors from the same family, and/or fault resilient firmware updates.

Firmware architecture supporting safe updates and multiple processor types

A method of electing a bootstrap processor from among a plurality of processor includes creating an atomic access shared location and electing one of said processors as the bootstrap processor.

Bootstrap processor election mechanism on multiple cluster bus systems

One aspect of the invention relates to a method for supporting hibernation despite the presence of hot-plugged nodes and non-deterministic boot operations. The method comprises invoking a management interrupt in response to a Hibernate request. The management interrupt is used to obtain and store platform configuration information into a non-volatile storage location. The platform configuration information includes data to indicate whether a next boot sequence for a platform occurs as a deterministic boot sequence or a non-deterministic boot sequence as well as a boot node identifier and a listing of an order in which processors of the platform are initialized.

Platform and method for supporting hibernate operations

One aspect of the invention relates to creation of a container object being part of software that is stored in platform readable medium and executed by a processor within a platform. The container comprises (i) a hardware identification object to identify to an operating system of the platform that a type of device represented by the container object is a node and (ii) a plurality of component objects to identify constituent components of the node. Another aspect of the invention is the distribution of BIOS to handle initiation of components of a substrate in response to hot-plug addition of that substrate.
