[dpdk-ci] Please install libatomic on your systems

[dpdk-ci] Please install libatomic on your systems

[David Marchand]

Hello all,

This is a call for action for CI(s).

Summary:
It is not mandatory to install libatomic on *all* systems, but still
recommended to avoid losing coverage on net/sfc.
But it is *mandatory* if the ABI check is ran on this system.


Details:
The net/sfc driver will now depend on the libatomic package.
This driver was always selected and built so far.
But now, if libatomic is not installed, this driver won't be compiled anymore.

Absence of this driver binary will be flagged as a failure by the ABI
check: the check interprets a hw support removal as a ABI breakage.

Example of output:
...
[2727/2727] Linking target drivers/librte_event_octeontx2.so.21.3
Error: cannot find librte_net_sfc.dump in
/home/dmarchan/builds/build-gcc-shared/install

Thanks David,

I've created an issue in our Jira to track this and we'll confirm when this
has been installed on all the systems in the UNH-IOL Community Lab.

Cheers,
Lincoln

Thanks, do you have a ETA?

Hi David,

I know Brandon started the work yesterday.  Note, the lab was closed July 2
through July 5, for the USA holiday. He can confirm what the ETA is on the
different parts of the lab (i.e. containers vs the bare-metal systems).

Cheers,
Lincoln

Hi David,

I have added the dependency to all containers / virtual machines that
run the ABI check test.
Could you also point me to the correct branch to compile with this new
dependency installed?
It would help me double check to ensure that I did not miss anything
and the ABI test results will remain stable on the dashboard.

Thanks,
Brandon

The main branch should pass the usual tests, compile, ut, abi.
Adding this dependency won't change anything for current main.

As for the patches requiring this update, they are from this patchset:
http://patchwork.dpdk.org/project/dpdk/list/?series=17590
Re-running the checks on this series should give all green flags.

Any update?
sfc series are blocked because of this.

Just confirming, we talked briefly about this during the community meeting.
This patchset should be fine now.
I will see if rerunning the unit test on the ARM machine will yield a
better result.

Thanks,
Brandon
