v1 -> v2: - Suggested by MST, use fast path for vring based performance sensitive API. - Reduce changes in tools/virtio.

Then I try to abstract virtqueue related methods in this series, the details changes see the comment of patch 'virtio: abstract virtqueue related methods'. Something is still remained: - __virtqueue_break/__virtqueue_unbreak is supposed to use by internal virtio core, I'd like to rename them to vring_virtqueue_break /vring_virtqueue_unbreak. Is this reasonable? - virtqueue_get_desc_addr/virtqueue_get_avail_addr/virtqueue_get_used_addr /virtqueue_get_vring is vring specific, I'd like to rename them like vring_virtqueue_get_desc_addr. Is this reasonable? - there are still some functions in virtio_ring.c with prefix *virtqueue*, for example 'virtqueue_add_split', just keep it or rename it to 'vring_virtqueue_add_split'? zhenwei pi (2): virtio: abstract virtqueue related methods tools/virtio: implement virtqueue in test drivers/virtio/virtio_ring.c | 285 +++++----------------- include/linux/virtio.h | 441 +++++++++++++++++++++++++++++++---- include/linux/virtio_ring.h | 26 +++ tools/virtio/linux/virtio.h | 355 +++++++++++++++++++++++++--- 4 files changed, 807 insertions(+), 300 deletions(-) -- 2.20.1 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
