The following change set introduces HAVE_VFIO_DEV_REQ_INTERFACE and used in the below files. drivers/bus/pci/linux/pci_vfio.c drivers/bus/pci/pci_common.c lib/librte_eal/linuxapp/eal/eal_interrupts.c However, Except the first file, the change missed to include <rte_vfio.h> where HAVE_VFIO_DEV_REQ_INTERFACE defined. This creates runtime following error on vfio-pci mode and kernel >= 4.0.0 combination. EAL: [rte_intr_enable] Unknown handle type of fd 95 EAL: [pci_vfio_enable_notifier]Fail to enable req notifier. EAL: Fail to unregister req notifier handler. EAL: Error setting up notifier!
