...b at linux-iscsi.org> Hi folks, This series adds a virtio_queue_valid() for use by virtio-pci code in order to prevent opreations upon uninitialized VQs, that is currently expected to occur during seabios setup of virtio-scsi. This also includes a vhost specific check for uninitialized VQs in vhost_verify_ring_mappings() to avoid this same case. Please review. --nab Michael S. Tsirkin (1): virtio: add API to check that ring is setup Nicholas Bellinger (2): virtio-pci: Add virtio_queue_valid checks ahead of virtio_queue_get_num vhost: Check+skip uninitialized VQs in vhost_verify_ring_mappings hw/vh...

From: Nicholas Bellinger <nab at linux-iscsi.org> This patch follows MST's recommendation to move checks for vhost_verify_ring_mappings() -> cpu_physical_memory_map() operations from MemoryListener->region_[add,del]() -> vhost_set_memory() into final MemoryListener->commit() -> vhost_commit() callback. It addresses the case where virtio-scsi vq ioport RAM re-mapping to read-only SeaBIOS ROM triggers a cpu_physical_m...

This is on top of Paolo and Nick's work. Current status: Basically, tcm_vhost + seabios works now. We still have one more issue, vhost_verify_ring_mappings fails. The hotplug also works with the latest tcm_vhost.ko hotplug patch. Asias He (1): disable vhost_verify_ring_mappings check Paolo Bonzini (2): virtio-scsi: create VirtIOSCSICommon vhost-scsi: new device supporting the tcm_vhost Linux kernel module configure | 15 ++-...
