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 preserve the data structures established in the earliest stage of initial power load, rather than each system firmware component rediscovering the hardware components of the system. Thus, the data structure is available at later stages for other firmware components. In a logical partitioning machine, the open firmware partition manager can utilize the data structure to support the partition's open firmware device tree construction. The partition manager customizes the copies of these data structures residing in the partition's memory. For hardware devices in the system but not belonging to the partition, the device information is cleared and marked invalid. After the data structures are established and updated by the earliest firmware I/O configuration component, the addresses of these structures are provided to the open firmware component. The open firmware copies these data structures to its internally safe working area and uses the copies for its normal operation. When runtime abstraction service firmware component is instantiated, the addresses of the structures of open firmware's copies are provided by the open firmware component to runtime abstraction service. Again, runtime abstraction service makes copies of these structures within its internally safe working space for its operation.

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。

摘要： A logical partition management apparatus and method for handling system reset interrupts (SRIS) are provided. The apparatus and method provide a SRI handler in the hypervisor that is capable of handling SRIs which may occur at any time during the operation of the multiprocessor computing system. The apparatus and method allow a hypervisor call to be completed before an SRI is handled. In this way, the SRI does not cause a processor of the symmetric multiprocessor (SMP) system to indefinitely hold a lock on a system resource and thus, other processors are not starved due to an inability to access the system resource.

摘要： A data processing system and method are disclosed for displaying a graphical depiction of the system configuration of the data processing system. Execution of a boot process of the data processing system is started. Prior to a completion of the boot process, a configuration of the data processing system is determined by the system itself. A graphical depiction of the configuration is then generated. The graphical depiction is then graphically displayed utilizing a display screen which is included in the data processing system. The graphical depiction illustrates each device included in the system as well as how the devices are interconnected. Thereafter, the execution of the boot process is completed. The steps of determining a configuration, generating a graphical depiction, and graphically displaying the graphical depiction are completed prior to completing the booting the data processing system, and thus prior to an operating system being executed by the data processing system.

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： A method, apparatus, and computer implemented instructions for controlling power in a data processing system having a plurality of logical partitions. Responsive to receiving a request to turn off the power for a logical partition within the plurality of logical partitions in the data processing system, a determination is made as to whether an additional partition within the plurality of logical partitions is present in the data processing system. The power is turned off in the data processing system in response to a determination an additional partition within the plurality of logical partitions is absent in the data processing system. The logical partition is shut down in response to a determination that an additional partition within the plurality of logical partitions is present in the data processing system. The mechanism of the present invention also provides for rebooting logical partitions. A request is received to reboot a logical partition within the plurality of logical partitions. A reset signal is activated only for each processor assigned to the logical partition.

摘要： A system and method for determining which processor is to be the master processor in a symmetric multi-processor (SMP) environment. The determination is made by boot-level code, i.e. the software program which executes first in a processor after it is brought on-line. Each processor in the SMP system is brought on-line independently of the other processors in the system, and each processor in the system can uniquely identify itself. As a processor comes on-line, it checks to see if a master processor has already been designated. If not, the processor checks to see if another processor, with a higher priority identifier, has identified itself as a working processor. If so, the processor commits to being a slave processor. If not, the processor indicates that it is available to be the master processor. A further check is made to ensure that only one processor has indicated that it is available to become the master processor. The likelihood that a particular processor will become the master processor may be increased or decreased by changing the processor's unique identifier. Thus, the system and method is controllable and changeable, without the need for any special or dedicated hardware. The probability that the system will always successfully select a master processor is increased, as is the probability that the system will initialize successfully even if one or more of the processors malfunctions.

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.
