摘要： In one embodiment, a processor includes error injection circuitry separate and independent of debug circuitry of the processor. This circuitry can be used by a software developer to seed errors into a write-back path to system memory to emulate errors for purposes of validation of error recovery code of the software. The circuitry can include a register to store an address within the system memory at which an error is to be injected, a detection logic to detect when an instruction associated with the address is issued, and injection logic to cause the error to be injected into the address within the system memory responsive to the detection of the instruction. Other embodiments are described and claimed.

摘要： In some implementations, a processor may include a machine check architecture having a plurality of error reporting registers able to receive data for machine check errors. A summary register may include a plurality of settable locations that each represents at least one of the error reporting registers. One or more of the settable locations in the summary register may be set to indicate whether one or more of the error reporting registers maintain data for a machine check error. Accordingly, when a machine check error occurs, the summary register may be accessed to identify if any error reporting registers in a processor's view contain valid error data, rather than having to read each of the error reporting registers in the processor's view.

摘要： Disclosed is an apparatus and a method to inject errors to a memory. In one embodiment, a dedicated interface includes an error injection system address register and an error injection mask register coupled to the error injection system address register. If the error injection system address register includes a system address that matches an incoming write address, the error injection mask register outputs an error to the memory.

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.

摘要： In a method for switching to a spare memory module during runtime, a processing system determines that utilization of an active memory module in the processing system should be discontinued. The processing system may then activate a mirror copy mode that causes a memory controller in the processing system to copy data from the active memory module to the spare memory module when the data is accessed in the active memory module. An operating system (OS) in the processing system may then access data in the active memory module to cause the memory controller to copy data from the active memory module to the spare memory module. The processing system may then reconfigure the memory controller to direct reads and writes to the spare memory module instead of the active memory module. Other embodiments are described and claimed.
