[PATCH mlx5-next 00/13] Move QP code to be under mlx5_ib responsibility

[PATCH mlx5-next 00/13] Move QP code to be under mlx5_ib responsibility

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Hi,

This series introduces simplified version of mlx5 command interface,
refactors the code to disconnect mlx5_core from QP logic and moves
qp.c to be under mlx5_ib responsibilities.

Next series will convert mlx5_core to this new interface, so at this
point I tried to keep the amount of changes to the minimum.

Thanks

[PATCH mlx5-next 01/13] net/mlx5: Provide simplified command interfaces

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Many mlx5_cmd_exec() callers are not interested in the output from that
command or have standard in/out structures. Those callers simply allocate
those structure on the stack and use sizeof() to provide in/out arguments.

In this naive approach provide simplified versions of mlx5_cmd_exec().

[PATCH mlx5-next 02/13] net/mlx5: Open-code create and destroy QP calls

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

FPGA, IPoIB and SW steering don't need anything from the
mlx5_core_create_qp() and mlx5_core_destroy_qp() except calls
to mlx5_cmd_exec().

Let's open-code it, so we will be able to move qp.c to mlx5_ib.

[PATCH mlx5-next 03/13] net/mlx5: Remove empty QP and CQ events handlers

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

The QP and CQ events functions do nothing except printing some debug
messages. There is nothing to do with this knowledge and such events,
so remove them.

[PATCH mlx5-next 07/13] net/mlx5: Remove extra indirection while storing QPN

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

The FPGA, SW steering and IPoIB need to have only QPN from the
mlx5_core_qp struct, so reduce memory footprint by storing QPN
directly.

[PATCH mlx5-next 08/13] net/mlx5: Replace hand written QP context struct with automatic getters

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

By changing debugfs to not use any QP related API, convert the debugfs
code to use MLX5_GET() directly to access QP context instead of hand
written struct.

[PATCH mlx5-next 09/13] net/mlx5: Remove Q counter low level helper APIs

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

mlx5 core users are encouraged to use low level API (mlx5_cmd_exec)
without the need of helper functions, do this for q counters, remove
helper functions and call mlx5_cmd_exec directly from users.

This will help reduce the total amount of code and reduction of the
mlx5_core symbol table.

[PATCH rdma-next 10/13] RDMA/mlx5: Delete Q counter allocations command

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Remove mlx5_ib implementation of Q counter allocation logic
together with cleaning boolean which controlled validity of the
counter. It is not needed, because counter_id == 0 means that
counter is not valid.

[PATCH mlx5-next 11/13] net/mlx5: Delete not-used cmd header

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

The structures defined in the cmd header are not used and can be safely
removed from the driver. This patch removes that file and deletes all
relevant includes.
