Hi, I got a question related to how virtio pmd driver work without UIO layer.
I see that in virtio PMD driver, DPDK will first try to init the device using UIO interfaces. If it fails, it will try to init by manipulating IO ports directly (see virtio_resource_init()). For the ioport case, is it okay to do it like this? E.g., in eth_virtio_dev_init(), we are resetting the virtio device, however, this device should still be owned by virtio-pci driver in the kernel. How is that working? Did I miss anything? Thanks in advance. Peter
