It appears that the vdev_device_list is empty - isn't this where the
probe function for VFIO lives?
rte_bus_probe, file ../lib/eal/common/eal_common_bus.c, vbus->name vdev
vdev_probe, file ../drivers/bus/vdev/vdev.c, PROBE, &vdev_device_list
0x56337bb30d30
vdev_probe, file ../drivers/bus/vdev/vdev.c, dev is (nil)
This is how I call basicfwd, am I missing something?
sudo examples/dpdk-skeleton -l 1 -n 4
Thanks,.
