DMA memory map/unmap callbacks are added to both\nvdev bus driver and virtio_user pmd to support address mapping.\nIn addition, minor fixes to existing virtio control path are also\nimplemented to make the new backend work.\n\nThis is a collaborative work done with Patrick Fu from Intel and\nAdrian Moreno from Red Hat. Thanks to them for their contributions.\n\nThe series has been tested with vdpasim and Intel IFC Kernel vDPA\ndrivers, and more lightly with Mellanox mlx5_vdpa on ConnectX-6 Dx.\n\nChanges in v2:\n-----------------\n * Split backend-type patch (Adrian)\n * Fix get_status size (Chenbo)\n * Various minro fixes (Chenbo)\n\nAdrian Moreno (1):\n net/virtio: move backend type selection to ethdev\n\nMaxime Coquelin (7):\n bus/vdev: add DMA mapping ops\n net/virtio: introduce DMA ops\n net/virtio: introduce Vhost-vDPA backend type\n net/virtio: check protocol feature in user backend\n net/virtio: adapt Virtio-user status size\n net/virtio: split virtio-user start\n net/virtio: introduce Vhost-vDPA backend\n\n drivers/bus/vdev/rte_bus_vdev.h | 46 ++-\n drivers/bus/vdev/vdev.c | 52 +++\n drivers/net/virtio/meson.build | 1 +\n drivers/net/virtio/virtio_user/vhost.h | 5 +\n drivers/net/virtio/virtio_user/vhost_user.c | 6 +-\n drivers/net/virtio/virtio_user/vhost_vdpa.c | 298 ++++++++++++++++++\n .../net/virtio/virtio_user/virtio_user_dev.c | 117 ++++---\n .../net/virtio/virtio_user/virtio_user_dev.h | 13 +-\n drivers/net/virtio/virtio_user_ethdev.c | 126 +++++++-\n 9 files changed, 607 insertions(+), 57 deletions(-)\n create mode 100644 drivers/net/virtio/virtio_user/vhost_vdpa.c" }
