[ovs-discuss] pci_map_resource(): cannot mmap(..): Invalid argument (0xffffffffffffffff)

[Fischetti, Antonio]

Can you try to specify the socket memory parameter
--socket-mem 1024,0
?

So the command
sudo ./ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile --detach

becomes
sudo ./ovs-vswitchd --dpdk -c 0x1 -n 4 --socket-mem 1024,0
-- unix:$DB_SOCK --pidfile –detach

Hi Charlie,
while this issue is happening with Fed23 can you check what are the 2 outputs of


1.       sudo $DPDK_DIR/tools/dpdk_nic_bind.py --status

and also


2.       lspci | grep 02:00

?

Antonio

Hello,

I am trying to set up openvswitch-2.5.0 with DPDK-2.2.0 by following "INSTALL.DPDK.md<http://INSTALL.DPDK.md>".

First tried with Ubuntu server 16.04 and it worked as expected.

But when tried with Fedora server 23, it hit the following error

EAL: pci_map_resource(): cannot mmap(10, 0x7f1800000000, 0x80000, 0x0): Invalid argument (0xffffffffffffffff)

when invoking

sudo ./ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile --detach

I tested it on the same hardware platform and followed the same instructions. Why it only failed with Fedora?

I am also attaching the detailed logs from both Ubuntu (working case) and Fedora (failing case).

Any help is appreciated.

Thanks,
Charlie
