Subject: [dpdk-dev] [PATCH 1/3] examples/eventdev_pipeline: configure max events based on dev info
Date: Fri, 1 Mar 2019 07:16:42 +0000 [thread overview]
Message-ID: <20190301071617.6570-1-pbhagavatula@marvell.com> (raw)
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Some eventdevs support configuring max events to be -1 (open system).
Check eventdev and event port configuration with eventdev info before
configuring them.
