[PATCH V6 0/5] virtio-scsi multiqueue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
