net/mlx5: Remove spinlock support from mlx5_write64

2019-04-02T19:49:37Z

As there is no user of mlx5_write64 that passes a spinlock to mlx5_write64, remove this functionality and simplify the function. Signed-off-by: Maxim Mikityanskiy Reviewed-by: Eran Ben Elisha Signed-off-by: Saeed Mahameed

net/mlx5e: Use CQE padding for Ethernet CQs

2018-12-11T22:52:20Z

Writing 64B CQEs to 128B cache lines results in a RMW operation. Padding the CQEs to 128B if possible improves performance on 128B cache line systems like PPC. Testing on PPC showed up to a 24% improvement in small packet throughput vs the default behavior, depending on the workload and system topology.

net/mlx5: EQ, Different EQ types

2018-11-20T18:07:00Z

In mlx5 we have three types of usages for EQs, 1. Asynchronous EQs, used internally by mlx5 core for a. FW command completions b. FW page requests c. one EQ for all other Asynchronous events 2. Completion EQs, used for CQ completion (we create one per core) 3. *Special type of EQ (page fault) used for RDMA on demand paging (ODP). *The 3rd type shouldn't be special at least in mlx5 core, it is yet another async events EQ with specific use case, it will be removed in the next two patches, and will completely move its logic to mlx5_ib, as it is rdma specific. In this patch we remove use case (eq type) specific fields from struct mlx5_eq into a new eq type specific structures. struct mlx5_eq_async; truct mlx5_eq_comp; struct mlx5_eq_pagefault; Separate between their type specific flows. In the future we will allow users to create there own generic EQs. for now we will allow only one for ODP in next patches. We will introduce event listeners registration API for those who want to receive mlx5 async events. After that mlx5 eq handling will be clean from feature/user specific handling.

net/mlx5: Set uid as part of CQ commands

2018-09-25T06:52:35Z

Set uid as part of CQ commands so that the firmware can manage the CQ object in a secured way. The firmware should mark this CQ with the given uid so that it can be used later on only by objects with the same uid. Upon DEVX flows that use this CQ (e.g. create QP command), the pointed CQ must have the same uid as of the issuer uid command. When a command is issued with uid=0 it means that the issuer of the command is trusted (i.e. kernel), in that case any pointed object can be used regardless of its uid.
