    • Methods to emulate a message signaled interrupt (MSI) with multiple interrupt vectors are described herein. An embodiment of the invention includes a memory decoder to monitor a predetermined memory location allocated to a device and to generate an emulated message signaled interrupt (MSI) signal in response to a posted write transaction to the predetermined memory location initiated from the device, and an interrupt controller, in response to the emulated MSI signal from the memory decoder, to invoke processing of a plurality of interrupts based on a plurality of interrupt vectors retrieved from the predetermined memory location, without receiving an actual MSI interrupt request from the device.
    • 这里描述了模拟具有多个中断向量的消息信号中断(MSI)的方法。 本发明的实施例包括:存储器解码器,用于监视分配给设备的预定存储器位置,并响应于从设备发起的预定存储器位置发布的写入事务,生成仿真消息信号中断(MSI)信号,以及 中断控制器,响应于来自存储器解码器的仿真MSI信号,基于从预定存储器位置检索的多个中断向量来调用多个中断的处理,而不从设备接收到实际的MSI中断请求。

    • An interrupt handling mechanism within a data processing system is used to assign interrupts among multiple interrupt presentation controllers while avoiding the use of a significant amount of signal lines. An interrupt input message from an interrupt source controller is input into an interrupt presentation controller. Fields are added to the interrupt input message to facilitate the assignment of the interrupt input message to an interrupt presentation controller. The input interrupt message is passed between the interrupt presentation controller in a sequential fashion such that the collection of controllers forms a logical ring. On the first circle of the ring, the priority of the processors capable of handling the interrupt is discovered. A second pass through the interrupt presentation controller is used to assign the first processor that is both capable of taking the interrupt and also has an equal or lower priority to that noted on the first pass as to best priority. The condition in which no acceptable processors are found for servicing the interrupt request is provided for by rejecting the interrupt.
    • 数据处理系统中的中断处理机制用于在多个中断呈现控制器之间分配中断,同时避免使用大量的信号线。 来自中断源控制器的中断输入消息被输入到中断呈现控制器中。 字段被添加到中断输入消息,以便于将中断输入消息分配给中断呈现控制器。 输入中断消息以顺序方式在中断呈现控制器之间传递,使得控制器的集合形成逻辑环。 在环的第一圈,发现能处理中断的处理器的优先级。 通过中断呈现控制器的第二次通过用于分配能够进行中断的第一处理器,并且具有与第一次通过中所指出的优先级相同或更低的优先级。 通过拒绝中断来提供不能接受处理器用于维护中断请求的条件。

    • A processing method, a chip set and a controller for supporting message signaled interrupt. A memory write transaction on a PCI bus is monitored. When the address of the system memory specified in the interrupt message of the write transaction is located at a range of a reserved interrupt address, the interrupting service sequence is performed. The reserved interrupt address is located in an address of a system memory. Thus, the data to be processed and the system-specified message are written in the buffer and arranged in sequence. The problem of nullwrite buffer latencynull is resolved, and is irrelevant to the level of the PCI bus. Many system specified messages can be stored in the system memory, so that multiple system message signaled interrupts issue from different peripheral components can be processed in the same interrupt service routine.
    • 一种处理方法,芯片组和用于支持消息信号中断的控制器。 监视PCI总线上的存储器写事务。 当在写事务的中断消息中指定的系统存储器的地址位于保留的中断地址的范围时,执行中断服务序列。 保留的中断地址位于系统存储器的地址中。 因此,要处理的数据和系统指定的消息被写入缓冲器中并且按顺序排列。 “写缓冲区延迟”的问题得到解决,与PCI总线的级别无关。 许多系统指定的消息可以存储在系统存储器中,从而可以在相同的中断服务程序中处理来自不同外设组件的多个系统消息信号中断。
