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:
