摘要： A method, apparatus, and computer instructions for halting input/output error propagation in the logically partitioned data processing system. All components associated with the bridge are identified to form a set of failed components in response to detecting an error state in a bridge within a set of bridges in the logical partitioned data processing system. An identification of the failed components is stored in which the identification is used by each partition during a boot process.

摘要： A system, method, and computer program product are disclosed for preventing machine crashes due to hard errors in one of multiple, different processors that are included in a logically partitioned data processing system. An error occurring in one of the processors is detected. A determination is then made regarding whether the processor has been deconfigured. The partition is then rebooted only in response to a determination that the processor has been deconfigured and will not be included in the partition processor resources. Thus, only the configured processors are rebooted. The deconfigured processor is not rebooted.

摘要： A method for automatically initializing the operational settings of a system from information stored within a non-volatile storage of an integrated circuit so that the operational requirements of the integrated circuit, which may be a microprocessor, are met by the system when the system is operating. During manufacturing test, environmental requirements of the integrated circuit are determined and stored within the non-volatile storage of the integrated circuit. During system initialization, environmental control values such as required operating voltage and frequency and cooling requirements are determined from the test values, which are read from the integrated circuit. The values are read by an interface of the system from an interface of the integrated circuit. System settings are controlled by the values to provide the required operating environment and the values may be captured within the system for subsequent operations and initialization sequences.

摘要： Methods, systems, and computer program products are provided for scheduling threads in a multiprocessor computer. Embodiments include selecting a thread in a ready queue to be dispatched to a processor and determining whether an interrupt mask flag is set in a thread control block associated with the thread. If the interrupt mask flag is set in the thread control block associated with the thread, embodiments typically include selecting a processor, setting a current processor priority register of the selected processor to least favored, and dispatching the thread from the ready queue to the selected processor. In some embodiments, setting the current processor priority register of the selected processor to least favored is carried out by storing a value associated with the highest interrupt priority in the current processor priority register.

摘要： A method, apparatus, and computer instructions for managing a set of devices in the data processing system. An alert is received through an external alert mechanism. The alert is at least one of a power alert and a thermal alert. In response to the alert, operation of a selected device within the set of devices is altered such that at least one of power usage and generation of heat by the selected device is reduced or restored to normal operation. The mapping of the reduced physical resources to logical resources is performed with no operating system intervention.
