2022-11-29net/mlx5: Generalize name of UMR alignment definitionTariq Toukan
Per the device spec, MLX5_UMR_MTT_ALIGNMENT is good not only for UMR MTT entries, but for all other entries as well, like KLMs and KSMs. Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Reviewed-by: Gal Pressman <gal@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2022-09-05RDMA/mlx5: Fix UMR cleanup on error flow of driver initMaor Gottlieb
The cited commit removed from the cleanup flow of umr the checks if the resources were created. This could lead to null-ptr-deref in case that we had failure in mlx5_ib_stage_ib_reg_init stage. Fix it by adding new state to the umr that can say if the resources were created or not and check it in the umr cleanup flow before destroying the resources.

2022-06-07RDMA/mlx5: Add a umr recovery flowAharon Landau
When a UMR fails, the UMR QP state changes to an error state. Therefore, all the further UMR operations will fail too. Add a recovery flow to the UMR QP, and repost the flushed WQEs.

Move mlx5_ib_update_mr_pas logic to umr.c, and use mlx5_umr_post_send_wait() instead of mlx5_ib_post_send_wait(). Since it is the last use of mlx5_ib_post_send_wait(), remove it.

2022-04-25RDMA/mlx5: Introduce mlx5_umr_post_send_wait()Aharon Landau
Introduce mlx5_umr_post_send_wait() that uses a UMR adjusted flow for posting WQEs. The next patches will gradually move UMR operations to use this flow. Once done, will get rid of mlx5_ib_post_send_wait(). mlx5_umr_post_send_wait gets already written WQE segments and will only memcpy it to the SQ. This way, we avoid packing all the data in a WR just to unpack it into the WQE.
