ABSTRACT:
Method, apparatus and system for controlling input/output adapter data flow operations in a data processing system that includes at least one of a traffic class mechanism in conjunction with virtual channel resources so as to be able to associate Load/Store and DMA flows to/from an input/output adapter, and a relaxed ordering mechanism for associating a relaxed ordering bit to Load/Store operations to an input/output adapter. Functionality for controlling the input/output adapter data flow is provided in a host bridge that connects the input/output adapter to a system bus of the data processing system.
