X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 11 Jun 2018 02:02:03 -0000 Hi, According to what I understand from: http://dpdk.org/doc/guides/eventdevs/index.html only 3 drivers currently use the eventdev API, NXP DPAA,NXP DPAA2 and Octeon SSOVF. My question is: is there any HW requirements from a NIC so that it will use the eventdev API for RX/TX instead of the traditional polling mode used by all the other PMD drivers ? Or theoretically and practically, one can implement DPDK driver using the eventndev API for Rx/Tx for any NIC ? Regards, Kevin
