The WWPN specified in configfs is passed to "-device vhost-scsi-pci".
The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not
available from the QEMU command-line. Instead, I hardcode it to zero.
Changes in Patch-v2:
- Add vhost_scsi_get_features() in order to determine feature bits
supports by host kernel (mst + nab)
- Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow
EVENT_IDX to be disabled by host in vhost_scsi_get_features()
- Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES
Changes in Patch-v1:
- Set event_idx=off by default (nab, thanks asias)
- Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to
re-enable in v3.10 (nab)
- Update to latest qemu.git/master HEAD
Changes in WIP-V3:
- Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha)
- Add CONFIG_VHOST_SCSI (asias, thanks stefanha)
- Add hotplug feature bit
Changes in WIP-V2:
- Add backend guest masking support (nab)
- Bump ABI_VERSION to 1 (nab)
- Set up set_guest_notifiers (asias)
- Set up vs->dev.vq_index (asias)
- Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias)
- Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias)
Howto:
Use the latest seabios, at least commit b44a7be17b
git clone git://git.seabios.org/seabios.git
make
cp out/bios.bin /usr/share/qemu/bios.bin
qemu -device vhost-scsi-pci,wwpn=naa.6001405bd4e8476d,event_idx=off
