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.
摘要:
A method and apparatus for functional redundancy check mode recovery is disclosed. A method in accordance with one embodiment includes detecting an event associated with a device within a data processing system, initiating a platform-independent device removal sequence for the device in response to detecting the event, virtually ejecting the device from the data processing system in response to initiating the platform-independent device removal sequence, and servicing the event associated with the device in response to virtually ejecting the device from the data processing system.

Embodiments of an invention related to context state management based on processor features are disclosed. In one embodiment, a processor includes instruction logic and state management logic. The instruction logic is to receive a state management instruction having a parameter to identify a subset of the features supported by the processor. The state management logic is to perform a state management operation specified by the state management instruction.

Embodiments of systems, apparatuses, and methods for performing privilege agnostic segment base register read or write instruction are described. An exemplary method may include fetching the privilege agnostic segment base register write instruction, wherein the privilege agnostic write instruction includes a 64-bit data source operand, decoding the fetched privilege agnostic segment base register write instruction, and executing the decoded privilege agnostic segment base register write instruction to write the 64-bit data of the source operand into the segment base register identified by the opcode of the privilege agnostic segment base register write instruction.
