RDMA/mlx5: Convert modify QP to use MLX5_SET macros

2020-05-27T19:07:49+00:00

Instead of hand crafted mlx5_qp_context and mlx5_qp_path use common MLX5_SET() macros. Link: https://lore.kernel.org/r/20200526115440.205922-7-leon@kernel.org Reviewed-by: Maor Gottlieb Reviewed-by: Mark Zhang Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

net/mlx5: Replace zero-length array with flexible-array

2020-05-11T01:05:38+00:00

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

RDMA/mlx5: Set lag tx affinity according to slave

2020-05-02T23:19:54+00:00

The patch sets the lag tx affinity of the data QPs and the GSI QPs according to the LAG xmit slave. For GSI QPs, in case the link layer is Ethenet (RoCE) we create two GSI QPs, one for each physical port. When the driver selects the GSI QP, it will consider the port affinity result. For connected QPs, the driver sets the affinity of the xmit slave. The above, ensures that RC QP and it's corresponding GSI QP will transmit from the same physical port.

net/mlx5: Remove Q counter low level helper APIs

2020-04-19T12:53:20+00:00

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. Reviewed-by: Saeed Mahameed Signed-off-by: Leon Romanovsky

IB/mlx5: Support set qp counter

2019-07-05T13:22:55+00:00

Support bind a qp with counter. If counter is null then bind the qp to the default counter. Different QP state has different operation: - RESET: Set the counter field so that it will take effective during RST2INIT change; - RTS: Issue an RTS2RTS change to update the QP counter; - Other: Set the counter field and mark the counter_pending flag, when QP is moved to RTS state and this flag is set, then issue an RTS2RTS modification to update the counter.
