Abstract: The disclosed embodiments provide a system that validates message-signaled interrupts. During operation, the system receives a message-signaled interrupt from a requesting device. This message-signaled interrupt includes an interrupt vector that identifies an interrupt, and is accompanied by an identification tag that identifies the source of the interrupt. The system uses the interrupt vector to access a stored tag from a tracking mechanism that associates source devices with their assigned interrupt vector(s). The system then compares the identification tag and the stored tag to validate the message-signaled interrupt.

Abstract: A method and apparatus for delivering a device driver to an operating system without user intervention. One or more operating systems (e.g., different operating system programs, different versions of one operating system) execute on a computer platform. During booting of an operating system a device is identified for which a driver is needed. The driver is requested from a service processor of the platform, which includes memory or storage for storing multiple device drivers (or multiple versions of one driver, for different operating systems). The driver is retrieved from the service processor's storage and delivered to the operating system.

Abstract: A system maintains a copy of data stored in a first memory device in a redundant distinct second memory device. Upon detecting an uncorrectable error in the first memory device, the system then relies on the copy of the data in the second memory device. The system, once it starts relying on the data in the second memory device, may then test the first memory device to determine if the uncorrectable error was due to a physical problem or a transient event. If the first memory device is then found to be working correctly, it may, in turn, become a redundant memory device for the second memory device.

Abstract: A method and system to allow user applications can access hardware platform-specific configuration information in a generic way. A platform independent framework lies on a layer that interfaces with the operating system layer. Accordingly, when a platform is changed, the operating system layer is notified of the change to facilitate informing the user of the change. This framework also has a plug-in publishing interface that is used to develop platform-specific modules to publish or export hardware configurations to other users. In another embodiment, this framework has a user interface that allows the user to make the necessary changes to the system management and hardware diagnostic tools whenever the platform is changed to ensure that the tools function correctly.
