[PATCH 0/7] libqos: add VIRTIO PCI 1.0 support

[Stefan Hajnoczi]

New VIRTIO devices are Non-Transitional.  This means they only expose the
VIRTIO 1.0 PCI register interface.

The libqos virtio-pci.c code only supports Legacy and Transitional devices (in
Legacy mode).  This patch series add VIRTIO PCI 1.0 support so that tests can
run against Non-Transitional devices too.

Note that this does not actually add VIRTIO 1.0 support to our tests.  That
would require extending feature negotiation (VIRTIO_F_VERSION_1).  I will look
at this as a separate step but the most pressing issue is getting libqos to
work with Non-Transitional virtio-pci devices.

Stefan Hajnoczi (7):
  libqos: extract Legacy virtio-pci.c code
  libqos: add iteration support to qpci_find_capability()
  libqos: pass full QVirtQueue to set_queue_address()
  libqos: add MSI-X callbacks to QVirtioPCIDevice
  libqos: expose common virtqueue setup/cleanup functions
  libqos: make the virtio-pci BAR index configurable
  libqos: add VIRTIO PCI 1.0 support
