From: Leon Romanovsky <leonro@xxxxxxxxxxxx> MLX5 IB HCA offers the memory key, dump_fill_mkey to increase performance, when used in a send or receive operations. It is used to force local HCA operations to skip the PCI bus access, while keeping track of the processed length in the ibv_sge handling. In this three patch series, we expose various bits in our HW spec file (mlx5_ifc.h), move unneeded for mlx5_core FW command and export such memory key to user space thought our mlx5-abi header file. Thanks Leon Romanovsky (1): net/mlx5: Add hardware definitions for dump_fill_mkey Yonatan Cohen (2): net/mlx5: Limit scope of dump_fill_mkey function IB/mlx5: Expose dump and fill memory key drivers/infiniband/hw/mlx5/cmd.c | 15 +++++++++++++++ drivers/infiniband/hw/mlx5/cmd.h | 1 + drivers/infiniband/hw/mlx5/main.c | 16 +++++++++++++++- drivers/net/ethernet/mellanox/mlx5/core/mr.c | 17 ----------------- include/linux/mlx5/driver.h | 2 -- include/linux/mlx5/mlx5_ifc.h | 4 +++- include/uapi/rdma/mlx5-abi.h | 3 ++- 7 files changed, 36 insertions(+), 22 deletions(-) -- 2.14.4 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
