Re: [dpdk-dev] [PATCH v2 0/9] rxq interrupt mode for virtio PMD

Forget to mention a key part, when we bind virtio to vfio-pci driver in the VM, we need to insert vfio kernel module like this: $ modprobe vfio enable_unsafe_noiommu_mode=1 $ modprobe vfio-pci Thanks, Jianfeng > -Original Message- > From: Tan, Jianfeng > Sent: Thursday, December 29, 201

[dpdk-dev] [PATCH v2 0/9] rxq interrupt mode for virtio PMD

v2: - Add PCI queue/irq config ops. - Move rxq interrupt settings before sending DRIVER OK. Historically, virtio PMD can only be binded to igb_uio or uio_pci_generic, and not for vfio-pci. Besides, quote from http://dpdk.org/doc/guides-16.11/rel_notes/release_2_1.html: "Per queue RX interrup
