摘要： A system, method, and computer-readable medium for detecting errors on a network. According to a preferred embodiment of the present invention, a network error manager retrieves a network topology from a master subnet manager, wherein the network includes a collection of devices coupled by a first interconnect type. When a connectivity failure is detected in the first interconnect type, the network error manager receives from the master subnet manager at least one event notification via a second interconnect type. An error log analysis component identifies at least one device among the collection of devices as a possible cause of the connectivity failure in the first interconnect type. The network error manager retrieves events from at least one device among the collection of devices that can influence a state of the first interconnect type.

摘要： An I/O adapter sharing mechanism in a logically partitioned computer system allows sharing a network I/O adapter between logical partitions in an efficient manner. A first logical partition owns (or controls) the I/O adapter, and a second logical partition desires to use (or share) the I/O adapter. An I/O adapter device driver that includes a hardware interface is provided in the first logical partition. A virtual device driver is provided in the second logical partition that provides a set of functions that is at least partially defined by querying the I/O adapter device driver in the first logical partition. The I/O adapter sharing mechanism includes a transfer mechanism that allows data to be transferred directly from the virtual device driver in the second logical partition to the I/O adapter without passing through the I/O adapter device driver in the first logical partition.

摘要： At least one input/output (I/O) firmware partition is provided in a partitioned environment to facilitate access to I/O resources owned by the at least one I/O firmware partition. The I/O resources of an I/O firmware partition are shared by one or more other partitions of the environment, referred to as consumer partitions. The consumer partitions use the I/O firmware partition to access the I/O resources. Since the I/O firmware partitions are responsible for providing access to the I/O resources owned by those partitions, the consumer partitions are relieved of this task, reducing complexity and costs in the consumer partitions.

摘要： A method, system, and apparatus for synchronizing device, node, and drawer addresses between two networks within a data processing system is provided. In one embodiment, a service processor assigns a plurality of SPCN addresses to each of a plurality of devices in the data processing system. System firmware then determines the RIO addresses corresponding to the plurality of devices. If one of the SPCN addresses is not the same as the RIO address for the corresponding device, node, or drawer, then the service processor reassigns a new SPCN address to the corresponding device, node, or drawer such that the new SPCN address is identical to the RIO address for a corresponding device, node, or drawer.

摘要： To emulate multi-threaded processing in an operating system supporting only single-threaded processes and single-level interrupts, the processor timer is started with a selected time-out period during execution of a master code thread. Processing of the master code thread proceeds until the timer interrupt, at which time the operating system timer interrupt service routine (ISR) transfers execution control to a slave code thread or slave code thread component. The slave code thread or component is executed in its entirety, at which time the timer is reset and execution control is returned to the master code thread, where processing resumes at the point during which the timer interrupt was asserted. To minimize disruption of the master code thread execution, a maximum latency should be enforced on the slave code thread, which may be accomplished by breaking the slave code thread into multiple components. The timer ISR maintains an index of the predetermined starting points within the slave code thread(s) with a pointer identifying the next slave code thread component to be selected when the timer interrupt is asserted. Processing thus alternates between the master code thread and the slave code thread or components, with different slave code thread components being selected in round-robin fashion. The duty cycle between the master code thread and the slave code thread or components may be varied by selection of the time-out period and the maximum latency allowed to slave code thread processing.
摘要翻译：为了在仅支持单线程进程和单级中断的操作系统中模拟多线程处理，处理器定时器在执行主代码线程期间以选定的超时周期启动。主代码线程的处理进行到定时器中断，此时操作系统定时器中断服务程序（ISR）将执行控制传送到从机代码线程或从机代码线程组件。从机代码线程或组件全部执行，此时定时器复位，执行控制返回到主代码线程，其中处理在定时器中断被断言的时刻恢复。为了最大限度地减少主代码线程执行的中断，应该在从属代码线程上执行最大延迟，这可以通过将从属代码线程分解成多个组件来实现。定时器ISR在定时器中断被断言时用指示器识别待选择的下一个从机代码线程组件来保持从属代码线程内的预定起始点的索引。因此，处理因此在主代码线程和从属代码线程或组件之间交替，其中以循环方式选择不同的从属代码线程组件。主代码线程和从属代码线程或组件之间的占空比可以通过选择超时周期和允许从机代码线程处理的最大延迟来改变。
