摘要： 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.

摘要： 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.

摘要： A firmware-based mechanism for creating, storing and retrieving variable-length records associated with error events occurring in a computer platform. The mechanism responds to error notifications by invoking a firmware-based error-handling module. The error-handling module retrieves processor-specific error information and may also interrogate the other components of the computer platform to determine their error status. Then, according to the nature of the discovered errors, the error-handling module may assemble the retrieved error information and status information into a variable-length error record, which the error-handling module may then store in a memory. On request from a processing agent, the error-handling module may retrieve a previously-stored error record and present it to the requesting agent. Thus, the invention provides a unified and standardized approach to computer error handling at the firmware level.

摘要： Methods and architectures for performing hardware error handling using coordinated operating system (OS) and firmware services. In one aspect, a firmware interface is provided to enable an OS to access firmware error-handling services. Such services enable the OS to access error data concerning platform hardware errors that may not be directed accessed via a platform processor or through other conventional approaches. Techniques are also disclosed for intercepting the processing of hardware error events and directing control to firmware error-handling services prior to attempting to service the error using OS-based services. The firmware services may correct hardware errors and/or log error data that may be later accessed by the OS or provided to a remote management server using an out-of-band communication channel. In accordance with another aspect, the firmware intercept and services may be performed in a manner that is transparent to the OS.
