Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/24. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/9dc3826a4a05b41de3325af68b61cb00599f4e90

Thanks.

Luca Boccassi

Subject: [PATCH] test: force IOVA mode on PPC64 without huge pages

[ upstream commit 6b07762e949036389030cf5a1a9bb8a1e4d6ee2d ]

On ppc64, without huge pages, pa would be the default but fails like:
  EAL: Cannot use IOVA as 'PA' since physical addresses are not available

On a normal system setup we'd expect an admin to set up huge pages
and for the unlikely case that they do not do that set iova=va themselves.
But the testing infrastructure does not have this conscious
admin that will do that, so fix test execution that by adjusting the
tests arguments accordingly if the conditions are met.
