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"

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi folks, This series contains patches required to update tcm_vhost <-> virtio-scsi connected hosts <-> guests to run on v3.5-rc2 mainline code. This series is available on top of target-pending/auto-next here: git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git tcm_vhost This includes the necessary vhost

Rusty, please review this, and consider for this merge window. This fixes the following virtio spec compliance issues: 1. on restore, drivers use device before setting ACKNOWLEDGE and DRIVER bits 2. on probe, drivers aren't prepared to handle config interrupts arriving before probe returns 3. on probe, drivers use device before DRIVER_OK it set Note that 1 is a clear violation of virtio

This patchset replace CONFIG_PM with CONFIG_PM_SLEEP for all virtio drivers and virtio pci driver. With patch 1/2, two compile warnings are eliminated for virtio pci driver, and patch 2/2 is a clean up for all virtio drivers as suggested by Amit Shah. Aaron Lu (2): virtio_pci: pm: Use CONFIG_PM_SLEEP instead of CONFIG_PM virtio: pm: use CONFIG_PM_SLEEP instead of CONFIG_PM

Changes from v4: rename virtio_enable_vqs_early() to virtio_device_ready() Note: Rusty requested we add a BUG_ON in the virtio_ring code. This can be done by a separate patch on top. Good for bisectability in case BUG_ON starts triggering :) Rusty, please review this, and consider for this merge window.

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.
