Hi guys,
I’m having varied results with compiling VPP for use with Mellanox ConnectX 5
drivers.
I have one ubuntu 18.04 box that compiled VPP 18.10 without problems and runs a
Mellanox ConnectX 5 card without problems, however:
I have several machines that are fitted with ConnextX 4 cards that I want to
run VPP on, on a CentOS environment. However: VPP with Mellanox connectX 4/5
driver (mlx5) compiles fine, but the NICs are not useable in VPP. The cards
are, however, available when I run “show pci”:
vpp# show pci

This happens while I use various guides. The working environment has been set
up using http://www.jimmdenton.com/vpp-1810-mellanox/
While the not working setups are with the same guide, or even the guides posted
on the Mellanox forum:
https://community.mellanox.com/s/article/How-to-Build-VPP-FD-IO-18-07-18-10.
These problems occur on CentOS 7, and RHEL 7.6 with VPP 1804, 1810 and 1901..
The debug logging shows nothing except for this:
/usr/bin/vpp[17639]: svm_map_region:633: segment chown [ok if client starts
first]: Operation not permitted (errno 1)
Anyone had the same problem or share a solution? I’ve found a few guys online
that had the same issues but did not find a solution
Regards,
Eyle
