摘要： Various address translation formats are available for use in obtaining system memory addresses for use by requestors in accessing system memory. The particular address translation format to be used by a given requestor, an example of which is an adapter function, is pre-registered in a device table entry associated with that requestor.

摘要翻译： 各种地址转换格式可用于获取系统内存地址以供请求者访问系统内存。 给定请求者（其示例是适配器功能）要使用的特定地址转换格式在与该请求者相关联的设备表条目中预先注册。

摘要： A measurement facility is provided for capturing and presenting fine-grained usage information for adapter functions in an input/output subsystem. Adapter specific input/output traffic is tracked on a per function basis and the results are dynamically presented to the user. This information is useful for performance tuning, load balancing and usage based charging, as examples.

摘要： Embodiments of the invention relate to scalable input/output (I/O) function level error detection, isolation, and reporting. An error is detected in a communication initiated between a function and the system memory, the communication including an I/O request from an application. Future communication between the function and the system memory is prevented in response to the detecting. The application is notified that the error in communication occurred in response to the detecting.

摘要： Embodiments of the invention relate to optimizing EDRAM refresh rates in a high performance cache architecture. A request is received from a requester to perform an operation on an I/O adapters. It is determined if the request is in a format other than a format supported by an I/O bus and if, the requester requires a completion response for the request. The request is transformed into the format supported by the I/O bus and is transmitted to the I/O adapter. The completion response is received from the I/O adapter, and includes an indicator that the request has been completed. The completion response is in the format supported by the I/O bus and is transmitted to the requester.

摘要： Embodiments of the invention relate to upbound input/output expansion requests and response processing in a PCIE architecture. A first request to perform an operation on a host system is intitiated. The first request is formatted for the first protocol and includes data that is required in order to process the first request. A second request is created in response to the first request, the second request includes a header and is formatted according to the second protocol. The data required to process the first request in the header of the second request is stored, and the second request is sent to the host system.
