FC-HBA's MMIO resource are mapped to guest physical address and machine address. I found both addresses need to be the same. I created the series of patches which map MMIO resource to the same address in guest physical address space and in machine address space. After applying this patch, my FC-HBA worked and IOMMU page fault did not occur. The patches are for only discussion. I'd like comments of developers. > I think that MMIO resource mapped via p2m table should be mapped via > IOMMU's page table too. In other word, XEN_DOMCTL_memory_mapping > hypercall should update not only p2m table, but also IOMMU's page table. Currently I don't think this is required.
