Abstract:
A firmware assisted error handling scheme in a computer system has been disclosed. In one embodiment, firmware is used to access one or more hardware-specific error registers within the computer system in response to a system management interrupt (SMI) trap. Using the firmware, an error record in a common error record format is constructed. The error record is made available to an operating system (OS) within the computer system.
Abstract:
In some embodiments, a PPM interface may be provided with functionality to facilitate to an OS RAS services for one or more hardware components, regardless of a particular platform hardware configuration, as long as the platform hardware and OS are in conformance with the PPM interface.

Abstract:
A method includes determining a plurality of memory addresses, each memory address being different from one another. The method further includes generating a plurality of system management interrupt interprocessor interrupts, each system management interrupt interprocessor interrupt having a corresponding processor in a plurality of processors in a system and each system management interrupt interprocessor interrupt including one of the plurality of memory addresses. The method further includes directing each system management interrupt interprocessor interrupt to the corresponding processor. An associated machine readable medium is also disclosed.
Abstract:
A non-volatile random access memory (NVRAM) is used in a computer system to store information that allows the NVRAM to autonomously initialize itself at power-on. The computer system includes a processor, an NVRAM controller coupled to the processor, and an NVRAM that comprises the NVRAM controller. The NVRAM is byte-rewritable and byte-erasable by the processor. The NVRAM stores a memory interface table containing information for the NVRAM controller to autonomously initialize the NVRAM upon power-on of the computer system without interacting with the processor and firmware outside of the NVRAM. The information is provided by the NVRAM controller to the processor to allow the processor to access the NVRAM.
