[Qemu-devel] [PATCH 0/3] virtio-pci: 1.0 tweaks

[Gerd Hoffmann]

  Hi,

Continued to look at virtio-1.0.  Added flags to turn off legacy/modern
mode for virtio devices.

Figured notification seems to not be adapted to virtio 1.0 yet:  Apply
this patchset, boot with -device virtio-net-pci,disable-legacy=on, watch
qemu blow up in virtio_pci_set_host_notifier_internal, because it uses
uninitialited proxy->bar without checking.  Looked closer, seems the
virtio 1.0 notification memory region isn't wired up yet ...

Gerd Hoffmann (3):
  virtio-pci: add flags to enable/disable legacy/modern
  virtio-pci: use bar0 for non-transitional devices
  virtio-pci: make QEMU_VIRTIO_PCI_QUEUE_MEM_MULT smaller
