摘要： A method, system, and product are described for creating and managing affinity between memory and processors in logical partitions in a data processing system. The data processing system includes multiple processors. A memory affinity data structure is established. The memory affinity data structure identifies ones of the processors that have a close affinity with each one of multiple regions of the system memory. A memory affinity parameter is established and is utilized to determine whether memory affinity is required for each one of the logical partitions. In response to a determination that memory affinity is required for one of the logical partitions, the memory affinity data structure is utilized by a partition manager for the logical partition to allocate an optimal amount of memory that has a close affinity to ones of the processors that are assigned to the logical partition.

摘要： A logical partition (LPAR) computer system for managing partition configuration data is disclosed, which includes a nonvolatile memory, and a plurality of logical partitions, each running independently from the other logical partitions. The system also includes a console coupled to the computer system for accepting logical partition configuration data input by an operator. The configuration data entered by the operator specifies the processors, I/O, and memory allocated to each logical partition defined for the system. The system further includes a set of tables maintained in the nonvolatile memory for storing the logical partition configuration data, such that the logical partition configuration data is persistent across system power cycles.

摘要： A method for managing deadlock in a data processing system during an IPL process includes monitoring the usage of locks in the Hardware Object Model (HOM) of the data processing system. The process further includes detecting a deadlock condition in response to an indication of the IPL process in the data processing system entering a hung state when at least one lock is in use. The process further includes handling the deadlock condition by performing one or more of the following: recording error information for the deadlock condition, and terminating the IPL process.

摘要： A method, apparatus, and computer instructions for testing hardware in a data processing system having multiple partitions. A monitor process in a first partition assigned to a first processor is initialized. A random code generation process in a second partition associated with a second processor is initialized. The random code generation process generates instructions and executes the instructions to test the second processor. The monitor process monitors the random code generation process and resets the second processor if the random code generation process fails.

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, system, and computer instructions for providing valid translation entries in the TCE table for all supported DMA addresses to prevent the occurrence of system errors due to prefetching. The mechanism of the present invention reserves a page in system memory. This reserved page is made unavailable to the operating system and may not be utilized by any software in the system. The reserved page is also written with all bytes set to 0xFF. The system firmware then selects a region in system memory for the TCE table. The TCE table is initialized, with all entries within the TCE table initialized to be valid as well as contain the corresponding address of the reserved page. In this manner, all supported DMA page addresses will have valid TCE entries which translate the DMA addresses into the reserved page memory. Thus, prefetched DMA addresses will not encounter invalid DMA address translation, and crash the system.

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.

摘要翻译： 在具有逻辑分区服务器的计算机系统中，除了全局锁之外，服务器的每个分区都具有自己的独立的锁和访问走廊。 当分隔锁的锁定后面是锁定全局锁时，系统将被序列化。 分区锁由系统固件控制，代表隔离每个分区的操作系统; 然而，全局锁由系统固件控制，以解锁，独立于分区锁的锁定/解锁状态。 以这种方式，在机器检查分析完成后，发出机器检查中断来解锁其分区锁定的OS的能力或无效是无关紧要的; 一旦机器检查分析完成，系统固件将解锁全局锁，让其他分区访问共享系统资源来运行自己的机器检查。
