[dpdk-stable] patch 'crypto/dpaa_sec: affine the thread portal affinity' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/39b13992e9cf6fce1ee2faf84bdd850a40861768

Thanks.

Subject: [PATCH] crypto/dpaa_sec: affine the thread portal affinity
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 22629f05f8832358d01872414e0e30c2c81e43d4 ]

DPAA requires the I/O shall be done in a HW portal context only.
The portal affinity is currently only being done in session create
and config APIs with the assumption that same thread will be used
for IO. This is causing issue.
This patch add support during I/O to check the HW portal affinity
and affine portal- if not affined already.

Fixes: 9a984458f755 ("crypto/dpaa_sec: rewrite Rx/Tx path")
