摘要：
Methods, systems, and apparatuses provide support for multiple address spaces in order to facilitate data movement. One system includes a host processor; a memory; a data fabric coupled to the host processor and to the memory; a plurality of input/output memory manage units (IOMMUs), each of the plurality of IOMMUs coupled to the data fabric; a plurality of root ports, each of the root ports coupled to a corresponding IOMMU of the plurality of IOMMUs; and a plurality of peripheral component endpoints, each of the plurality of peripheral component endpoints coupled to a corresponding root port of the plurality of root ports, wherein each of the root ports comprises hardware control logic operative to: synchronize the plurality of root ports; receive, from the corresponding peripheral component endpoint, a direct memory access (DMA) request; and provide the DMA request to the corresponding IOMMU of the plurality of IOMMUs.
