WebVFIO is similar to the UIO framework in that it provides a method to map a device into user space memory allowing register access of the device. VFIO also controls the SMMU such that DMA has a virtualized view of memory similar to the CPUs. Unlike UIO, VFIO has very few examples, minimal documentation and most of the examples are PCI related. ... WebHi Damjan, My main goal is to use the PF inside the VPP using DPDK in addition to SR-IOV connection to the VMs. Currently (before enabling SR-IOV VFs ) all interfaces is connected to VPP with DPDK using VFIO-PCI driver.
