Called "DMA Remapping" in intel speak, this is where the config option name comes from. Advantages: (1) 32bit PCI devices can DMA to memory above 4G, thus the need for swiotlb (i.e. bounce buffers) is gone. (2) It allows kvm to pass through PCI devices to guests securely. thanks, Gerd _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
