摘要： A method is provided for creating and managing tables for routing packets through an environment that includes multiple hosts and shared PCI switches and adapters. A Destination Identification (DID) field in the PBA is appended to a transaction packet dispatched through the PCI switches, wherein a particular DID is associated with a particular host or system image, and thus identifies the physical or virtual end point of its packet. In one embodiment, packets are routed through PCI switches in a distributed computer system comprising multiple root nodes, wherein each root node includes one or more hosts. The embodiment includes the step of creating a table or like data structure in a specified one of the switches. When a particular host of one of the root nodes becomes connected to the specified switch, a PCI Configuration Master (PCM), residing in one of the root nodes, is operated to enter a destination identifier or DID into the table. The DID is then appended as an address component, to packets directed through the specified switch from the particular host to one of the adapters. The destination identifier is also used to determine that a PCI packet, routed through the specified switch from one of the adapters, is intended for the particular root node.
摘要翻译：提供了一种创建和管理表以通过包括多个主机和共享PCI交换机和适配器的环境路由数据包的方法。 PBA中的目的地标识（DID）字段附加到通过PCI交换机分派的事务分组，其中特定的DID与特定主机或系统映像相关联，并且因此标识其分组的物理或虚拟终点。在一个实施例中，分组通过包括多个根节点的分布式计算机系统中的PCI交换机路由，其中每个根节点包括一个或多个主机。该实施例包括在指定的一个开关中创建表或类似数据结构的步骤。当一个根节点的特定主机连接到指定的交换机时，驻留在其中一个根节点的PCI配置主机（PCM）被操作以在表中输入目的地标识符或DID。然后，将DID作为地址组件附加到通过指定的交换机从特定主机引导到其中一个适配器的数据包。目的地标识符还用于确定通过指定交换机从其中一个适配器路由的PCI数据包是针对特定根节点的。

摘要： A method and an apparatus are provided for restricting input/output device peer-to-peer operations in a data processing system to improve reliability, availability, and serviceability. A peer-to-peer (P2P) control logic is provided to perform a lookup of P2P lookup table entries. Each P2P lookup table entry comprises bus, device and function number fields, optional control fields, and an accept/reject bit. Upon receiving a communication request from a requesting I/O device, P2P control logic implemented in either a logical bridge or an I/O device identifies the requester ID of the request and determines if a match exists in the P2P lookup table entries. If a match is found and the accept/reject bit is enabled, I/O operations can be received from the requester.

摘要： A mechanism is provided for sharing resources among logical partitions in a logical partitioned data processing system and for managing the changes to resources in such a way that the sharing operating systems are able to handle the various transitions in a graceful manner. Four hypervisor functions plus a specific return code manage the granting of access of resources owned by one partition to another (client) partition, accepting of granted resources by client partitions, returning of granted resources by client partitions, and rescinding of access by the owning partition. These four hypervisor functions are invoked either explicitly by the owning and client partitions or automatically by the hypervisor in response to partition termination. The hypervisor functions provide the needed infrastructure to manage the sharing of logical resources among partitions.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed for managing DMA write page faults using a pool of substitute pages. The computer system's platform resolves a DMA write page fault for a page that is dedicated to an I/O adapter. The I/O adapter attempts to write DMA data to the page. A determination is made that the page is unavailable for writing. The DMA data is then written to data locations in a substitute page that was selected from the pool of substitute pages. A flag is then set in a flag location for each one of the data locations. The flag locations correspond to the data locations. When a flag is set, the flag indicates that DMA write data is present in the data location that corresponds to that flag's flag location.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed in a data processing environment that includes host computer systems that are coupled to adapters utilizing a switched fabric for routing packets between the host computer systems and the adapters. A unique destination identifier is assigned to one of the host computer systems. A portion of a standard format packet destination address is selected. Within a particular packet, the portion is set equal to the unique identifier that is assigned to the host computer system. The particular packet is then routed through the fabric to the host computer system using the unique destination identifier.

摘要： A PCI control manager provides address translation protection tables in switches in a PCI fabric. The PCI control manager discovers the fabric and provides a virtual tree for each root complex. A system administrator may then remove endpoints that do not communicate with the root complex to configure the PCI fabric. The PCI control manager then provides updated ATPT tables to the switches. When a host or adapter is added, the master PCM goes through the discovery process and the ATPT tables and adapter routing tables are modified to reflect the change in configuration. The master PCM can query the ATPT tables and adapter routing tables to determine what is in the configuration. The master PCM can also destroy entries in the ATPT tables and adapter routing tables when a device is removed from the configuration and those entries are no longer valid.

摘要： In a distributed computer system having multiple root nodes, a challenge protocol is provided, for use in determining or confirming the root node in which a PCI Configuration Manager (PCM) actually resides. This node is referred to as the master node. The challenge procedure is activated whenever the identity of the PCM, which is determined by the root node in which it resides, appears to be uncertain. The challenge procedure resolves this uncertainty, and enables the PCM to continue to configure routings throughout the system. In a useful embodiment, a method is directed to a distributed computer system of the above type which is further provided with PCI switches and with adapters that are available for sharing by different nodes. The method includes the steps of selecting a first one of the root nodes to be master root node, and operating the first root node to query the configuration space of a particular one of the PCI switches. The method further includes detecting information indicating that a second root node is considered to be the master root node for the particular switch. A challenge protocol is implemented in response to this detected information, to seek confirmation that the first root node is the master root node. The configuration space querying procedure is continued if the first root node is confirmed to be the master root node, and is otherwise aborted.
摘要翻译：在具有多个根节点的分布式计算机系统中，提供质询协议，用于确定或确认PCI配置管理器（PCM）实际驻留的根节点。该节点称为主节点。每当由其驻留的根节点确定的PCM的身份似乎不确定时，激活挑战过程被激活。挑战程序解决了这种不确定性，并使PCM能够在整个系统中继续配置路由。在有用的实施例中，一种方法针对上述类型的分布式计算机系统，其进一步提供有PCI交换机以及可由不同节点共享的适配器。该方法包括以下步骤：将根节点中的第一个选择为主根节点，以及操作第一根节点以查询特定一个PCI交换机的配置空间。该方法还包括检测指示第二根节点被认为是特定交换机的主根节点的信息。响应于该检测到的信息来实现质询协议，以寻求第一根节点是主根节点的确认。如果第一个根节点被确认为主根节点，则会继续进行配置空间查询过程，否则中止。

摘要： A mechanism for temporarily stalling selected Direct Memory Access (DMA) operations in a physical I/O adapter in order to permit migration of data between physical pages that are subject to access by the physical I/O adapter. When a request for a DMA to a physical page in system memory is received from an input/output adapter, a migration in progress (MIP) bit in a translation control entry (TCE) pointing to the physical page is examined, wherein the MIP bit indicates whether migration of the physical page referenced in the TCE to another location in system memory is currently in progress. If the MIP bit indicates a migration of the physical page is in progress, the DMA from the input/output adapter is temporarily stalled while other DMA operations from other input/output adapters to other physical pages in system memory are allowed to continue.
摘要翻译：暂时停止物理I / O适配器中选定的直接内存访问（DMA）操作的机制，以便允许在物理I / O适配器访问的物理页之间迁移数据。当从输入/输出适配器接收到对系统存储器中的物理页面的DMA的请求时，检查指向物理页面的翻译控制条目（TCE）中正在进行的迁移（MIP）位，其中MIP位指示TCE中引用的物理页面迁移到系统内存中的另一个位置是否正在进行中。如果MIP位指示物理页面的迁移正在进行，则来自输入/输出适配器的DMA将暂时停止，而允许从其他输入/输出适配器到系统内存中其他物理页面的其他DMA操作继续。
