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 Fam Zheng (1): virtio-mmio: Process vrings more proactively Fei Li (1): virtio-mmio: support multiple interrupt vectors drivers/virtio/virtio_mmio.c | 238 +++++++++++++++++++++++++++++++++++-------- 1 file changed, 196 insertions(+), 42 deletions(-) -- 2.11.0
