With current implementation the vgic is initialized very late,
when the VM is started, on the first VCPU run execution. This
series kicks the initialization off on machine init done instead.
Among other things, this earlier VGIC initialization allows to
have a simpler handling of VFIO. VFIO 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:
- [PATCH] KVM: arm/arm64: vgic: add init entry to VGIC KVM device
Tested on Calxeda Miday with VFIO platform use case
