X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" This commit adds support for the TILE-Gx platform, as well as the TILE CPU architecture. This architecture port is fairly simple due to its reliance on generics for most arch stuff.
