A system and method for injecting hardware errors into a microprocessor system is described. In one embodiment, a software interface between system software and system firmware is established. Software test and debug for software error handlers may thus be supported. The software interface may support both a query mode call and a seed mode call. When a query mode call is issued, it may request whether or not the system firmware and hardware support the injection of a specified kind of error. A return from this call may be used to make a list of supported errors for injection. When a seed mode call is issued, the corresponding error may be injected into the hardware.

System and method for error injection using a flexible program interface field

Use of data poisoning techniques may permit proactive operating system recovery without needing to always bringing down the operating system when uncorrectable errors are encountered.

Poisoned error signaling for proactive OS recovery

A processing system may include an operating system (OS) and one or more specialized error handling modules to be registered with the OS after the processing system is powered on. The OS may also include a master policy module. The specialized error handling module may collect error data from a component of the processing system, and may generate abstracted error data, based at least in part on the collected error data. The master policy module may determine a recovery action to be taken, based at least in part on the abstracted error data. The OS may also include an error collection routine that calls one or more specialized error handling modules in response to detecting a hardware error. The error collection routine may also retrieve information from firmware in response to detecting the hardware error. Other embodiments are described and claimed.
