This series implements virtio-scsi queue steering, which gives performance improvements of up to 50% (measured both with QEMU and tcm_vhost backends).
This version rebased on Rusty's virtio ring rework patches, which has already gone into virtio-next today. We hope this can go into virtio-next together with the virtio ring rework pathes.
V6: rework "redo allocation of target data" (James) fix comments (Venkatesh) rebase to virtio-next
V5: improving the grammar of 1/5 (Paolo) move the dropping of sg_elems to 'virtio-scsi: use virtqueue_add_sgs for command buffers'. (Asias)
V4: rebase on virtio ring rework patches (rusty's pending-rebases branch)
V3 and be found http://marc.info/?l=linux-virtualization&m=136067440717154&w=2
It would probably be easier to get it in via Rusty's tree because of the prerequisites. James, can we get your Acked-by?
Paolo Bonzini (3): virtio-scsi: pass struct virtio_scsi to virtqueue completion function virtio-scsi: push vq lock/unlock into virtscsi_vq_done virtio-scsi: introduce multiqueue support
Wanlong Gao (2): virtio-scsi: redo allocation of target data virtio-scsi: reset virtqueue affinity when doing cpu hotplug
