openvswitch : dpdk support

So, I recently had to install openvswitch primarily to use it with dpdk.

While, dpdk is even listed as a dependency of openvswitch, it seems the package pullling from the repos actually doesn't have dpdk support.

I had to compile and install a version of openvswitch myself so as to enable dpdk support( --with-dpdk=shared )

Is there any reason why dpdk support is not enabled by default?

How did you verify that ?

Does the previous version 3.5.1 have that support ?

Moderator Note
not in aur issue, moving to Pacman & Package Upgrade Issues for now.

1) There's a message indicating that in the logs

2) https://gitlab.archlinux.org/archlinux/ … penvswitch - The PKGBUILD file in this repo, (I cannot tell for sure that that's what is being used) but yeah, the ./configure part of the PKGBUILD file seems to indicate that dpdk support isn't enabled.

Re: openvswitch : dpdk support

It would help if you posted that message.

The configure parts of PKGBUILDs for repo packages use upstream defaults as much as possible and only set what is necessary.
Whether dpdk support is default enabled by upstream or needs to be activated at buildtime is something I don't know .

Have you tried running openvswitch 3.5.21 and if so did that have dpdk support ?

Sidenote :
This could warrant a bug report against repo openvswitch, but you haven't provided enough info to determine if that's the correct follow up.

No, I have not tried openvswitch-3.5.21...

I guess that answers my original question. Thanks

Re: openvswitch : dpdk support

Thanks, that clarifies the openvswitch packages currently doesn't support dpdk .
Since it depends on dpdk that's weird and smells like a bug .

In my opinion there's now enough info to file a bug report at https://gitlab.archlinux.org/archlinux/ … work_items.
