Subject: [libvirt] [PATCH v4 0/3] Allow PCI virtio on ARM "virt" machine
Virt machine in qemu since v2.3.0 has PCI generic host controller, and can use
PCI devices. 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 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. Test suite framework needs to be improved.
Changes since v2:
Complete rework, use different approach
- Correctly model PCI Express bus on the machine. It is now possible to
explicitly specify <address-type='pci'> with attributes. This allows to
attach not only virtio, but any other PCI device to the model.
- Default is not changed and still mmio, for backwards compatibility with
existing installations. PCI bus has to be explicitly specified.
- Check for the capability in correct place, in v2 it actually did not work
Changes since v1:
- Added capability based on qemu version number
- Recognize also "virt-" prefix
