Hi Bruce, I was seeing a similar problem on my system when attaching a virtual function port. testpmd> port attach 0000:06:10.0 Attaching a new port... EAL: PCI device 0000:06:10.0 on NUMA socket -1 EAL: probe driver: 8086:10ed rte_ixgbevf_pmd EAL: PCI memory mapped at 0x10000 EAL: pci_map_resource(): cannot mmap(27, 0x14000, 0x4000, 0x1000): Invalid argument (0xffffffffffffffff) EAL: Requested device 0000:06:10.0 cannot be used EAL: Driver, cannot attach the device This patch seems to solve the problem. Regards, Bernard.
