[PATCH v1 0/2] virtio-mmio: support multiple interrupt vectors

[Fei Li]

Hi,

This patch series implements multiple interrupt vectors support for
virtio-mmio device. This is especially useful for multiqueue vhost-net
device when using firecracker micro-vms as the guest.

Test result:
With 8 vcpus & 8 net queues set, one vhost-net device with 8 irqs can
receive 9 times more pps comparing with only one irq:
- 564830.38 rxpck/s for 8 irqs on
- 67665.06 rxpck/s for 1 irq on

Please help to review, thanks!

Have a nice day
Fei
