Subject: [dpdk-stable] [19.11 PATCH] crypto/dpaa_sec: affine the thread portal affinity
Date: Thu,  3 Jun 2021 17:47:28 +0530
Message-ID: <20210603121728.30576-1-hemant.agrawal@nxp.com> (raw)

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")
Cc: stable@dpdk.org
