[RFC PATCH] virtio-mmio: support for multiple irqs
...ng. This patch support virtio-mmio to request multiple irqs like virtio-pci. With this patch and qemu assigning multiple irqs for virtio-mmio device, it's ok to use vhost-net with irqfd on arm/arm64. As arm doesn't support msi-x now, we use GSI for multiple irq. In this patch we use "vm_try_to_find_vqs" to check whether multiple irqs are supported like virtio-pci. Is this the right direction? is there other ways to make virtio-mmio support multiple irq?
