Subject: [dpdk-stable] patch 'config: enable packet prefetching with Meson' has been queued to LTS release 18.11.11

Message-ID: <20201123171222.79398-5-ktraynor@redhat.com> (raw)
In-Reply-To: <20201123171222.79398-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to LTS release 18.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/27/20. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/ebc0bdf697037882baea2f45a3b9da75ab47ddd7

Thanks.

Kevin.

Subject: [PATCH] config: enable packet prefetching with Meson

[ upstream commit 048a2aa3f30c90c7f9339a17bfd1e663e379625f ]

With Make build system, RTE_PMD_PACKET_PREFETCH was enabled
by default. It got lost when transitioning to Meson build
system.

In order to avoid performance changes, this patch enables
packet prefetching in rte_config.h.

Fixes: 9314afb68a53 ("drivers: add infrastructure for meson build")
