Hi All: This series tries to add the support for control virtqueue in vDPA. Control virtqueue is used by networking device for accepting various commands from the driver. It's a must to support multiqueue and other configurations. When used by vhost-vDPA bus driver for VM, the control virtqueue should be shadowed via userspace VMM (Qemu) instead of being assigned directly to Guest. This is

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.
