    摘要: One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications. Each I/O adapter event notification includes the setting of one or more specific indicators in system memory and an interruption request, the first of which results in a pending I/O adapter interruption request. While a request for an I/O adapter interruption is pending, subsequent message signaled interruption requests are converted to I/O adapter event notifications, but do not result in additional requests for I/O adapter interruptions.

    摘要翻译: 一个或多个来自一个或多个输入/输出(I / O)适配器的信号中断请求被转换为I / O适配器事件通知。 每个I / O适配器事件通知包括系统内存中的一个或多个特定指示符的设置和中断请求,其中第一个会导致挂起的I / O适配器中断请求。 当I / O适配器中断的请求处于待处理状态时,后续的消息信号中断请求将转换为I / O适配器事件通知,但不会导致对I / O适配器中断的其他请求。
