Abstract

A method for coupling transactions with a configurable ordering controller in a computer system. The method comprises sending, by a coupling device, first data packets with an unordered attribute being set to an ordering controller. The method further comprises sending, by the coupling device, second data packets with requested ordering to the ordering controller, back-to-back after the first data packets, without waiting until all of the first data packets are completed. The method further comprises sending, by the ordering controller, the first data packets to a memory subsystem in a relaxed ordering mode, wherein the ordering controller sends the first data packets to the memory subsystem in an arbitrary order, and wherein the ordering controller sends the second data packets to the memory subsystem after sending all of the first data packets to the memory subsystem.
