vdpasim: vDPA device simulator This patch implements a software vDPA networking device. The datapath is implemented through vringh and workqueue. The device has an on-chip IOMMU which translates IOVA to PA. For kernel virtio drivers, vDPA simulator driver provides dma_ops. For vhost driers, set_map() methods of vdpa_config_ops is implemented to accept mappings from vhost. Currently, vDPA device simulator will loopback TX traffic to RX. So the main use case for the device is vDPA feature testing, prototyping and development. Note, there's no management API implemented, a vDPA device will be registered once the module is probed. We need to handle this in the future development. Signed-off-by: Jason Wang <jasowang@redhat.com> Link: https://lore.kernel.org/r/20200326140125.19794-9-jasowang@redhat.com Signed-off-by: Michael S.
