Here is v2 (three counting the RFC) of the virtio-scsi driver. Unlike previous versions, it includes migration support.
The only change in the spec has been s/UNDERRUN/OVERRUN/g. Paolo Bonzini (13): dma-helpers: make QEMUSGList target independent dma-helpers: add dma_buf_read and dma_buf_write dma-helpers: add accounting wrappers ahci: use new DMA helpers scsi: pass residual amount to command_complete scsi: add scatter/gather functionality scsi-disk: enable scatter/gather functionality scsi: add SCSIDevice vmstate definitions scsi-generic: add migration support scsi-disk: add migration support virtio-scsi: add basic SCSI bus operation virtio-scsi: process control queue requests virtio-scsi: add migration support Stefan Hajnoczi (2): virtio-scsi: Add virtio-scsi stub device virtio-scsi: Add basic request processing infrastructure Makefile.target | 1 + default-configs/pci.mak | 1 + default-configs/s390x-softmmu.mak | 1 + dma-helpers.c | 36 +++ dma.h | 20 +- hw/esp.c | 3 +- hw/ide/ahci.c | 82 +----- hw/lsi53c895a.c | 2 +- hw/pci.h | 1 + hw/s390-virtio-bus.c | 24 ++ hw/s390-virtio-bus.h | 2 + hw/scsi-bus.c | 143 +++++++++- hw/scsi-disk.c | 120 +++++++- hw/scsi-generic.c | 25 ++ hw/scsi.h | 22 ++- hw/spapr_vscsi.c | 2 +- hw/usb-msd.c | 2 +- hw/virtio-pci.c | 42 +++ hw/virtio-pci.h | 2 + hw/virtio-scsi.c | 607 +++++++++++++++++++++++++++++++++++++ hw/virtio-scsi.h | 36 +++ hw/virtio.h | 3 + 22 files changed, 1074 insertions(+), 103 deletions(-) create mode 100644 hw/virtio-scsi.c create mode 100644 hw/virtio-scsi.h -- 1.7.7.1
