Hi: This series implements the packed virtqueue state support for vDPA. This is done via extending the vdpa_vq_state to support packed virtqueue. For virtio-vDPA, an initial state required by the virtio spec is set. For vhost-vDPA, the packed virtqueue support still needs to be done at both vhost core and vhost-vDPA in the future. Please review. Tested with packed=on/off via virtio_vdpa driver. Change since V1: - unbreak mlx5_vdpa build Thanks Eli Cohen (1): virtio/vdpa: clear the virtqueue state during probe Jason Wang (3): vdpa: support packed virtqueue for set/get_vq_state() virtio-pci library: introduce vp_modern_get_driver_features() vp_vdpa: allow set vq state to initial state after reset drivers/vdpa/ifcvf/ifcvf_main.c | 4 +-- drivers/vdpa/mlx5/net/mlx5_vnet.c | 8 ++--- drivers/vdpa/vdpa_sim/vdpa_sim.c | 4 +-- drivers/vdpa/virtio_pci/vp_vdpa.c | 42 ++++++++++++++++++++++++-- drivers/vhost/vdpa.c | 4 +-- drivers/virtio/virtio_pci_modern_dev.c | 21 +++++++++++++ drivers/virtio/virtio_vdpa.c | 15 +++++++++ include/linux/vdpa.h | 25 +++++++++++++-- include/linux/virtio_pci_modern.h | 1 + 9 files changed, 109 insertions(+), 15 deletions(-) -- 2.25.1
