These work fine. Now I try to unbind these ports so that they can be controlled by DPDK. (I = load the igb_uio ofcourse as usual) Now I first unbind the port represented by p1p1, this works and DPDK takes = over this port. However, now when I try to unbind the p1p2, it gives the following error [root@localhost DPDK]# ./tools/pci_unbind.py --bind=3Digb_uio p1p2 Error: bind failed for 0000:01:00.1 - Cannot bind to driver igb_uio Error: unbind failed for 0000:01:00.1 - Cannot open /sys/bus/pci/drivers//u= nbind I cannot unbind any other ports either. The one port which is unbound works fine with DPDK application without issu= es. So the question is, why are the other ports giving issues ? The same machine works with Fedora18 properly and is able to unbind all the= 4 ports.
