Tested with virtio-pci vDPA driver. Please review. Changes since V1: - use dev->vq_index to calculate the virtqueue index - remove the unused host_notifier_set Jason Wang (2): vhost-vdpa: skip ram device from the IOTLB mapping vhost-vdpa: map virtqueue notification area if possible hw/virtio/vhost-vdpa.c | 97 ++++++++++++++++++++++++++++++---- include/hw/virtio/vhost-vdpa.h | 6 +++ 2 files changed, 93 insertions(+), 10 deletions(-) -- 2.25.1
