Hi, I am having an issue with binding a nic of type 82545EM to dpdk. I am using a fedoracore23 VM on MAC with VMFusion.
./dpdk_nic_bind.py -b uio_pci_generic 0000:02:02.0 Error: bind failed for 0000:02:02.0 - Cannot bind to driver uio_pci_generic Error: unbind failed for 0000:02:02.0 - Cannot open /sys/bus/pci/drivers//unbind it is unbound from e1000, repeating the command: ./dpdk_nic_bind.py -b uio_pci_generic 0000:02:02.0 Error: bind failed for 0000:02:02.0 - Cannot bind to driver uio_pci_generic I repeated the same test on a ubuntu vm running on Virtualbox with NIC type 82450EM In this case, the device is able to bind successfully to uio_pci_generic driver. There is a igb_uio module that present. The device cannot be bound to the igb_uio driver. My question is that why is the device being able to be bound to uio_pci_generic driver on ubuntu and not on fedoracore? (Albeit on fedora device is 82545EM and on ubuntu it is 82540EM). Both these are reported as tested by Intel: ? Emulated Intel? 82540EM Gigabit Ethernet Controller [8086:100e] ? Emulated Intel? 82545EM Gigabit Ethernet Controller [8086:100f] http://www.intel.com/content/dam/www/public/us/en/documents/release-notes/dpdk-release-notes.pdf Are there any debugs to collect that can shed some light?
