From: Eli Cohen <e...@mellanox.com> The patches that follow constitute the driver for Mellanox's 5th generation of HCAs named Connect-IB.
The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4 with the substantial difference that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. In this sense, it can be perceived as a library. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw. The patches are partitioned to avoid exceeding the 100KB vger.kernel.org limitation. They are divided such that the first three ones have the code of the mlx5_core driver, and the last five the code of the mlx5_ib driver. Only the last patch per driver adds the Makefiles and Kconfigs, to make things robust for future bisections. PPC is not yet supported but support will be included in the near future. changes from V0: - Per Dave's request, cross posting to both netdev and linux-rdma, to see if there are comments from netdev on the core driver.
