Hi, I am using DPDK1.4 with Fedora 19 [I am aware that DPDK1.4 release notes do not claim Fedora 19 as supported, but I tried nevertheless and reporting this issue]
When I bootup, I see the following in lscpi output [I have two dual port 82599 10 Gb NIC's] 01:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) 01:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) 03:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) 03:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) I also have 4 interfaces in ifconfig output shown by Fedora 19 - p1p1, p1p2, p2p1, p2p2 corresponding to the 4 ports above. 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 at localhost DPDK]# ./tools/pci_unbind.py --bind=igb_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//unbind I cannot unbind any other ports either. The one port which is unbound works fine with DPDK application without issues. 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.
