ABSTRACT:
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.
