摘要： 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.

摘要： 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.

摘要： The disclosed embodiments provide a system that uses unused bits in a memory pointer. During operation, the system determines a set of address bits in a address space that will not be needed for addressing purposes during program operation. Subsequently, the system stores data associated with the memory pointer in this set of address bits. The system masks this set of address bits when using the memory pointer to access the memory address associated with the memory pointer. Storing additional data in unused pointer bits can reduce the number of memory accesses for a program and improve program performance and/or reliability.

摘要： 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.

摘要： A method and mechanism for managing timers in a multithreaded processing system. A storage device stores a plurality of count values corresponding to a plurality of timers. A read address generator is coupled to convey a read address to the storage device. The read address generator is configured to maintain and increment a first counter. In response to determining the counter does not equal a predetermined value, the mechanism conveys a first read address for use in accessing a count value in the storage device. In response to determining the count equals the predetermined value, the mechanism conveys a second read address for use in accessing a count value in the storage device. The predetermined value is utilized to repeat accesses to a given count value a predetermined number of times.

摘要： 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.

摘要： A system for preventing damage to cargo shipped in air-ride suspension semi-trailers loaded on railroad flat cars which comprise at least part of a freight train is provided. The system comprises a coupling element connected to the air brake line of the freight train. The coupling element is connected to an air reservoir mounted on the flat car or on the semi-trailer and supplies compressed air to the reservoir from the brake line of the train. The coupling element includes a valve to prevent air from flowing from the train brake line to the air reservoir when the air pressure in the brake line drops below a predetermined safety level to prevent unwanted activation of the train's brakes. The air reservoir is connected to the air line of the semi-trailer and provides compressed air to the air bags which comprise the air suspension system of the semi-trailer. When the bags are inflated with compressed air from the brake line of the train, they suspend the semi-trailer above its rear axles and cushion the semi-trailer from the lateral sway and rough ride of the flat car.

摘要： A centrifugal gas compressor impeller is assembled to a rotatable shaft with two friction washers having conical surfaces mating with respective opposite conical surfaces of the impeller that are concentric to a central impeller aperture through which a threaded bolt is passed and threaded into a threaded aperture at the end of the rotatable shaft. The angles of concentricity for the conical surfaces of the washer are slightly different than the angles of concentricity of the mating impeller surfaces so that a friction lock is obtained between the shaft and impeller and also the impeller and washer apertures are slightly larger than the bolt shaft diameter so that an impeller centering relative to the shaft is assured during assembly.
