From 95276abaaf0a3e605e99a306f1923f46c3037a64 Mon Sep 17 00:00:00 2001 From: Matan Azrad Date: Sun, 2 Feb 2020 16:03:41 +0000 Subject: [PATCH] vdpa/mlx5: introduce Mellanox vDPA driver Add a new driver to support vDPA operations by Mellanox devices. The first Mellanox devices which support vDPA operations are ConnectX-6 Dx and Bluefield1 HCA for their PF ports and VF ports. This driver is depending on rdma-core like the mlx5 PMD, also it is going to use mlx5 DevX to create HW objects directly by the FW. Hence, the common/mlx5 library is linked to the mlx5_vdpa driver. This driver will not be compiled by default due to the above dependencies. Register a new log type for this driver.
