patch 'test/debug: fix IOVA mode on PPC64 without huge pages' has been queued to stable release 24.11.4

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/03/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/4b0f9391cee6bbc06b297687bb41f2e2b2e1fbd0

Thanks.

Kevin

Subject: [PATCH] test/debug: fix IOVA mode on PPC64 without huge pages

[ upstream commit c94a9de51c2100659b25105ef433b88f3e6dc5af ]

1001s Running binary with argv[]:'/tmp/autopkgtest.LvdXhc/build.6vT/src/build/app/dpdk-test' '--file-prefix=debug' '-l' '0' '--no-huge' '-m' '2048'
<...>
1001s EAL: Cannot use IOVA as 'PA' since physical addresses are not available

This is similar to the commit
6b07762e9490 ("test: force IOVA mode on PPC64 without huge pages")

on ppc64 iova-mode=pa is the default, but it doesn't work with --no-huge,
so add --iova-mode=va to the test arguments.

Fixes: 2b403dd8fb37 ("test/debug: fix crash with mlx5 devices")
