Subject: [PATCH v3 0/5] virtio-scsi multiqueue
Date: Tue, 12 Feb 2013 14:06:26 +0100 [thread overview]
Message-ID: <1360674391-2661-1-git-send-email-pbonzini@redhat.com> (raw)
This series implements virtio-scsi queue steering, which gives
performance improvements of up to 50% (measured both with QEMU and
tcm_vhost backends). The patches build on top of the new virtio APIs
at http://permalink.gmane.org/gmane.linux.kernel.virtualization/18431;
the new API simplifies the locking of the virtio-scsi driver nicely,
thus it makes sense to require them as a prerequisite.
Changes from the previous post, which can be found at
http://permalink.gmane.org/gmane.linux.kernel.virtualization/17869:
- patches 1 and 2 ("virtio: add functions for piecewise addition of
buffers", "virtio-scsi: use functions for piecewise composition of
buffers") split into their own series
- new cleanup patch "virtio-scsi: push vq lock/unlock into virtscsi_vq_done"
- reorganized code to move ACCESS_ONCE in a clearer place
- included Wanlong Gao's CPU hotplug patches
Ok for 3.9? It would probably be easier to get it in via Rusty's tree
because of the prerequisites. James, can I get your Acked-by?
