virtio-scsi driver

From:  Paolo Bonzini <pbonzini@redhat.com>
To:  linux-kernel@vger.kernel.org
Subject:  [PATCH v4 0/3] virtio-scsi driver
Date:  Fri, 20 Jan 2012 17:45:36 +0100
Message-ID:  <1327077939-7084-1-git-send-email-pbonzini@redhat.com>
Cc:  linux-scsi@vger.kernel.org, Rusty Russell <rusty@rustcorp.com.au>, kvm@vger.kernel.org, "Michael S . Tsirkin" <mst@redhat.com>, Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>, Mike Christie <michaelc@cs.wisc.edu>

This is the first implementation of the virtio-scsi driver, a virtual
HBA that will be supported by KVM.  It implements a subset of the spec,
in particular it does not implement asynchronous notifications for either
LUN reset/removal/addition or CD-ROM media events, but it is already
functional and usable.

Other matching bits:

- spec at http://people.redhat.com/pbonzini/virtio-spec.pdf

- QEMU implementation at git://github.com/bonzini/qemu.git,
  branch virtio-scsi

Please review.  I would like this to be included in 3.3, since the
possibility of regressions is obviously zero.

Paolo Bonzini (3):
  virtio-scsi: first version
  virtio-scsi: add error handling
  virtio-scsi: add power management support

v3->v4: renamed VIRTIO_SCSI_S_UNDERRUN to VIRTIO_SCSI_S_OVERRUN;
    fixed 32-bit compilation; added power management support;
    adjusted calls to virtqueue_add_buf
