Hi QEMU folks,
The following is the patch-v2 series to support vhost-scsi-pci within
the upstream QEMU tree.
This includes the refactoring of existing virtio-scsi code from Paolo
to allow a VirtIOSCSICommon structure that is shared amoungst existing
virtio-scsi-pci device and new vhost-scsi-pci device code.
Currently this code requires Asias's seabios bugfixes (commit 5a7730db5
and b44a7be17), and two other tcm_vhost patches to reset vq->last_used_idx
after seabios handoff and disable EVENT_IDX from GET_FEATURES that's
currently in flight for v3.9.0 kernel code.
There is a seperate issue with seabios virtio-scsi that's causing a failure
in vhost_verify_ring_mappings() is still being tracked down, but this series
should now be getting close to a merge minus this last outstanding item.
Changes in Patch-v2:
- Move ->get_features() assignment to virtio_scsi_init() instead of
virtio_scsi_init_common() (nab)
- 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() (mst)
- Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES (mst)
- Drop vhost_verify_ring_mappings() enable-only hack (mst)
A big thanks to Paolo, Asias, MST, and Stefan for all of their efforts
on this series.
Thank you,
