Subject: [dpdk-dev] [PATCH 4/4] vdpa/mlx5: set default event mode to polling
Date: Wed,  2 Dec 2020 23:36:43 +0000
Message-ID: <1606952203-23310-4-git-send-email-xuemingl@nvidia.com> (raw)
In-Reply-To: <1606952203-23310-1-git-send-email-xuemingl@nvidia.com>

For better performance and latency, this patch sets default event
handling mode to polling mode which uses dedicate thread per device to
poll and process event.
