Subject: arm_gicv2m: set kvm_gsi_direct_mapping and kvm_msi_via_irqfd_allowed
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9718e4ae362d2f221ec028cdacefafc593ef1357;p=qemu.git

arm_gicv2m: set kvm_gsi_direct_mapping and kvm_msi_via_irqfd_allowed

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.
