This provides performance improvement as well as > vhost-net with irqfd support for virtio-net. However libvirt currently > does not allow ARM virt machine to have PCI devices. This patchset adds > the necessary support. > > Changes since v4: > - Rebased onto current master > - Added possibility to plug virtio-net-pci adapter directly into PCIe bus. > This is necessary for irqfds to work in qemu. > Changes since v3: > - Capability is based not on qemu version but on support of "gpex-pcihost" > device by qemu > - Added a workaround, allowing to pass "make check". The problem is that > test suite does not build capabilities cache. Unfortunately this means > that correct unit-test for the new functionality currently cannot be > written.

It is now possible to > explicitly specify <address-type='pci'> with attributes.
