platform signaling can be
setup on reset handler, making sure the VGIC is ready, at that time,
to accept injected virtual IRQs.
Depends on the following kernel patch:

Hi Baptiste,
Although I understand you may be tempted to transform the Calxeda basic
node creation function into something more generic, we

After introduction of kvm_arch_msi_data_to_gsi, kvm_gsi_direct_mapping
now can be set on ARM. Also kvm_msi_via_irqfd_allowed can be set,
depending on kernel irqfd support, hence enabling VIRTIO-PCI with
vhost back-end.
