Abstract
A data processing system includes a system fabric coupling a coherence manager and an input/output (I/O) requestor. The I/O requestor issues a first snoop request of a first I/O store operation and a subsequent second snoop request of a second I/O store operation. Each of the first and second snoop requests specifies an update to a respective storage location identified by a coherent memory address. The I/O requestor receives respective ownership coherence responses for each of the first and second I/O store operations. The respective first and second ownership coherence responses indicate the coherence manager has concurrent coherence ownership of the memory address for both the first and second I/O store operations. In response to receipt of each of the ownership coherence responses, the I/O requestor issues respective first and second execute coherence responses to command the coherence manager to initiate updates to the respective storage locations.
