摘要： A resource and partition manager of the preferred embodiments includes a lock mechanism that operates on a plurality of locks that control access to individual I/O slots. The resource and partition manager uses the lock mechanism to obtain a lock on an I/O slot when transferring control of the I/O slot to a logical partition that is powering on and when removing the I/O slot from a logical partition that is powering off. The resource and partition manager uses the lock mechanism to remove control of an I/O slot from, or return control to, an operating logical partition in order to facilitate hardware service operations on that I/O slot or on the physical enclosure in which it is contained.

摘要： A resource and partition manager of the preferred embodiments includes a lock mechanism that operates on a plurality of locks that control access to individual hardware resources. The resource and partition manager uses the lock mechanism to obtain a lock on a hardware resource when transferring control of the hardware resource to a logical partition that is powering on and when removing the hardware resource from a logical partition that is powering off. The resource and partition manager uses the lock mechanism to remove control of a hardware resource from, or return control to, an operating logical partition in order to facilitate hardware service operations on that hardware resource or on the physical enclosure in which it is contained.

摘要： An interrupt and message batching apparatus and method reduces the number and frequency of processor interrupts and resulting context switches by grouping I/O completion events together with a single processor interrupt in a manner that balances I/O operation latency requirements with processor utilization requirements to optimize overall computer system performance. The invention sends a message from a processor complex to an I/O adapter on an I/O bus commanding an I/O device connected to the I/O adapter to perform a function. Upon completion of the commanded function, the message processor in the I/O adapter generates a message and sends it to the processor complex on the I/O bus. The message is enqueued in the message queue of the memory, a message count is updated, and processor complex interrupt is signalled if and when the message count exceeds a message pacing count. A signalling timer may also be programmed with a fast response time value if the message has a relatively high latency or with a slow response time value if the message has a relatively low latency. The signalling timer is started when the message is enqueued and the processor complex interrupt is then signalled when the message count exceeds the message pacing count or when the signalling timer has elapsed.
摘要翻译：中断和消息批处理设备和方法通过将I / O完成事件与单个处理器中断分组，以使I / O操作等待时间要求与处理器利用率要求平衡来优化，从而减少处理器中断和结果上下文切换的数量和频率整体计算机系统性能。本发明在I / O总线上从处理器复合体向I / O适配器发送消息，命令连接到I / O适配器的I / O设备执行功能。完成命令功能后，I / O适配器中的消息处理器会生成一条消息，并将其发送到I / O总线上的处理器复合体。该消息在存储器的消息队列中排队，消息计数被更新，并且当消息计数超过消息步调计数时以及何时发送处理器复杂中断。如果消息具有相对较高的延迟，或者如果消息具有相对低的延迟，则信令定时器也可以被编程为具有快速的响应时间值。当消息排入队列时，启动信令定时器，然后当消息计数超过消息起搏计数或信令定时器过去时，信号通知处理器复杂中断。
