Hi All: This series introduces API for reporing IOVA range. This is a must for userspace to work correclty: - for the process that uses vhost-vDPA directly to properly allocate IOVA - for VM(qemu), when vIOMMU is not enabled, fail early if GPA is out of range - for VM(qemu), when vIOMMU is enabled, determine a valid guest address width Please review. Thanks Jason Wang (4): vdpa:

Hi all: This series tries to support batched IOTLB updating vhost-vdpa. Currently vhost-vdpa accepts userspace mapping via IOTLB API, and it can only forward one mapping to IOMMU or device through IOMMU API or dma_map(). Though set_map() is designed to have the capability to pass an rbtree based mapping to vDPA device, it's still be called at least once for each VHOST_IOTLB_UPDATE or
