Description Yaakov Selkowitz 2017-02-06 21:57:59 UTC 
Recent versions of dpdk advertise support for ARM and POWER platforms.

https://koji.fedoraproject.org/koji/taskinfo?taskID=17637841 (aarch64)
https://koji.fedoraproject.org/koji/taskinfo?taskID=17637843 (ppc64le)

Unfortunately, the latter fails when linking the test app:

test_pmd_ring.o: In function `test_pmd_ring':
/builddir/build/BUILD/dpdk-16.11/app/test/test_pmd_ring.c:451: undefined reference to `rte_eth_from_rings'

/builddir/build/BUILD/dpdk-16.11/app/test/test_pmd_ring_perf.c:170: undefined reference to `rte_eth_from_ring'

FWIW, armv7hl is also supposedly included in the sources, but numactl currently ExcludeArch's it.

Comment 2 Yaakov Selkowitz 2017-02-06 23:06:05 UTC 
Found a solution for ppc64le in OpenSUSE[1]:

%ifarch ppc64le
setconf CONFIG_RTE_LIBRTE_PMD_RING n
%endif

https://koji.fedoraproject.org/koji/taskinfo?taskID=17638975 succeeded with that.

FWIW, they also setconf CONFIG_RTE_LIBRTE_DISTRIBUTOR n on both aarch64 and ppc64le.  I'm not sure why though, as the build succeeds without it.

Patch for rawhide
Comment 4 Neil Horman 2017-02-07 16:58:59 UTC 
I'm a bit lost as to why the ring pmd would fail on arm, its a software only construct.  I'll fix that up and get this submitted, thanks!
Comment 5 Fedora End Of Life 2017-02-28 11:12:05 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.
Comment 6 Fedora End Of Life 2018-05-03 08:25:15 UTC 
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
