摘要： A method, apparatus, and computer instructions for preserving trace data in a logical partitioned data processing system. A call is received from a partition in a plurality of partitions to register a buffer in the partition for the trace data. The call includes a pointer to the buffer. The buffer is associated with a trace routine in platform firmware. The trace routine stores the trace data for calls made by the partition to the platform firmware in the buffer.

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 interrupt is generated for all processors in a multiprocessor system when a critical datapath experiences an error. Serialization code in the interrupt handling routine for that interrupt suspends all processors except one and places the suspended processors in a waiting queue while the one processor handles the error. After the error has been handled, the remaining processors are allow to execute the interrupt handler, which simply exits detecting no error.

摘要： In a computer system having a logical-partitioned server, each partition of the server is provided with its own separate lock and access corridor, in addition to a global lock. When the locking of a partition lock is followed by the locking of the global lock, the system is serialized. The partition locks are controlled by system firmware on behalf of an OS isolating each partition; however, the global lock is controlled by the system firmware to be unlocked independent of the lock/unlock status of the partition locks. In this manner, the ability or inability of an OS that issued a machine check interrupt to unlock its partition lock after the machine check analysis is complete is irrelevant; once the machine check analysis is complete, the system firmware unlocks the global lock, giving other partitions access to shared system resources to run their own machine checks.

摘要： A method, computer program product, and data processing system for handling errors or other events in a logical partition (LPAR) data processing system is disclosed. When an operating system is initialized in a logical partition, it registers its capabilities for handling particular errors or other events with management software. When an error or other event affecting that logical partition occurs, the management software checks to see if the particular error or event is one that the operating system is capable of handling. If so, the operating system is notified. Otherwise, the management software directs the operating system to take other appropriate action, such as termination of the operating system and/or partition.

摘要： A method, system, and computer program product for enforcing logical partitioning of input/output slots within a data processing system is provided. In one embodiment, the system includes a hypervisor and at least one DMA address checking component. The hypervisor receives non-direct-memory-access requests for access to input/output slots and prohibits devices within one logical partition from accessing the input/output slots assigned to a different logical partition. The DMA address checking component receives direct-memory-access requests and prohibits requests for addresses not within the same logical partition as the requesting device from being completed. Requests with addresses corresponding to the same logical partition as the requesting device are placed on the primary PCI bus by the DMA address checking component for delivery to the system memory.

摘要： A method and apparatus for detecting an error condition during initialization of a multiprocessor data processing system is provided. A master processor identification indicator is initialized to an initial value by a service processor in the data processing system. The master processor identification indicator may be a location in nonvolatile RAM to protect data integrity. One of the plurality of processors in the multiprocessor system is selected to be the master processor by being released by the service processor and winning the “race condition” to fetch the first instruction from memory for program execution. This processor then sets the master processor identification indicator to a unique processor identification value. The initial value may be a spoof number indicating whether the master processor has yet written its unique processor identification value. At some later point in time, the service processor detects a freeze or hang condition in the data processing system. The service processor reads the value of the master processor identification indicator and reports the value of the master processor identification indicator to indicate which processor among the plurality of processors in the data processing system was selected as the master processor prior to the detection of the hang condition.
