Subject: [dpdk-dev] [PATCH v3 21/42] event/octeontx2: add devargs to force legacy mode
Date: Fri, 28 Jun 2019 23:53:32 +0530 [thread overview]
Message-ID: <20190628182354.228-22-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20190628182354.228-1-pbhagavatula@marvell.com>
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Octeontx2 SSO by default is set to use dual workslot mode.
Add devargs option to force legacy mode i.e. single workslot mode.
Example:
--dev "0002:0e:00.0,single_ws=1"

+- ``Force legacy mode``
+
+ The ``single_ws`` devargs parameter is introduced to force legacy mode i.e
+ single workslot mode in SSO and disable the default dual workslot mode.
+ For example::

+ --dev "0002:0e:00.0,single_ws=1"
