Subject: [dpdk-stable] [PATCH V2] crypto/octeontx: enable unbinding for the OCTEON TX crypto engines
Date: Fri, 13 Sep 2019 08:40:03 +0200
Message-ID: <15217f0aa7b041c895dd1a956e703bb48df6c453.1568356742.git.thierry.herbelot@6wind.com> (raw)
In-Reply-To: <22e44c87c26193219900e738dcda9b1390efcb9c.1568217224.git.thierry.herbelot@6wind.com>

Like for Ethernet ports, the OCTEON TX crypto engines must first be unbound
from their kernel module, then rebound to vfio-pci, before being usable
in DPDK.

As this capability is detected at runtime by dpdk-pmdinfo, add the info
in the PMD registering directives.

Then an external script can be used for bind and unbind.

Fixes: bfe2ae495ee268 ('crypto/octeontx: add PMD skeleton')

V2: only "vfio-pci" is needed by this PMD
