> your kernel provider needs to decide whether they favor device assignment or p2p
Thanks Alex! The hardware requirements for P2P (switch, high performance EPs) are such that we really only expect CONFIG_P2P_DMA to be enabled in specific instances and in those instances the users have made a decision to favor P2P over IOMMU isolation. Or they have setup their PCIe topology in a way that gives them IOMMU isolation where they want it and P2P where they want it.
