    • PROBLEM TO BE SOLVED: To improve system performance by reducing an operation cost of inter-processor interruption. SOLUTION: The sequence of the inter-processor interruption of a sender side processor side includes the followings. The memory writing of an inter-processor interruption requests to a linear address X is carried out (305). A sender side processor determines whether a value is changed or not by polling a specific memory location, and waits a positive response for receiving the inter-processor interruption from the receiver side processor (310). If the memory location has changed its value, a normal operation is resumed (315). COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:通过降低处理器间中断的运营成本来提高系统性能。 解决方案:发送器侧处理器侧的处理器间中断的顺序包括以下内容。 执行对线性地址X的处理器间中断请求的存储器写入(305)。 发送器侧处理器通过轮询特定存储器位置来确定值是否改变,并且等待从接收器侧处理器(310)接收处理器间中断的肯定响应。 如果存储器位置已经改变其值,则恢复正常操作(315)。 版权所有(C)2010,JPO&INPIT

    • An apparatus and system may include a peripheral device, such as an interrupt controller or Peripheral Component Interconnect (PCI) bridge device, having a memory-mapped legacy register and a PCI dummy register. The legacy register may be accessed by a Basic Input/Output System (BIOS) as part of a power-on initialization sequence for the peripheral device, and the dummy register may be accessed during a hot-plug operation using code executed by an Operating System (OS). An article, including a machine-accessible medium, may contain data capable of causing a machine to carry out a method of representing a peripheral device which includes identifying the peripheral device as a legacy device in a name space, such as an Advanced Configuration and Power Interface (ACPI) name space, and identifying the peripheral device as a dummy PCI device capable of being accessed during a hot-plug operation.
    • 装置和系统可以包括具有存储器映射的遗留寄存器和PCI伪寄存器的外围设备,诸如中断控制器或外围组件互连(PCI)桥接器件。 传统寄存器可以由基本输入/输出系统(BIOS)作为外围设备的上电初始化序列的一部分访问,并且可以在热插拔操作期间使用由操作系统执行的代码来访问虚拟寄存器 (OS)。 包括机器可访问介质的文章可以包含能够使机器执行表示外围设备的方法的数据,其包括将外围设备识别为名称空间中的传统设备,诸如高级配置和电源 接口(ACPI)名称空间,并将外围设备识别为能够在热插拔操作期间被访问的虚拟PCI设备。
