| | | | | | | | | | | | GRE RFC defines a 32 bit key field. NVGRE RFC splits the 32 bit key field to 24 bit VSID (gre_key_h) and 8 bit flow entropy (gre_key_l).

* net/mlx5: EQ, Introduce atomic notifier chain subscription APISaeed Mahameed2018-11-263-3/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use atomic_notifier_chain to fire firmware events at internal mlx5 core components such as eswitch/fpga/clock/FW tracer/etc.., this is to avoid explicit calls from low level mlx5_core to upper components and to simplify the mlx5_core API for future developments. Simply provide register/unregister notifiers API and call the notifier chain on firmware async events. Example: to subscribe to a FW event: struct mlx5_nb port_event; MLX5_NB_INIT(&port_event, port_event_handler, PORT_CHANGE); mlx5_eq_notifier_register(mdev, &port_event); where: - port_event_handler is the notifier block callback. - PORT_EVENT is the suffix of MLX5_EVENT_TYPE_PORT_CHANGE. The above will guarantee that port_event_handler will receive all FW events of the type MLX5_EVENT_TYPE_PORT_CHANGE. To receive all FW/HW events one can subscribe to MLX5_EVENT_TYPE_NOTIFY_ANY. The next few patches will start moving all mlx5 core components to use this new API and cleanup mlx5_eq_async_int misx handler from component explicit calls and specific logic.

This API will be used in downstream patch to move page fault (RDMA ODP) EQ logic into mlx5_ib rdma driver, hence it will use a generic EQ. Current mlx5 EQ allocation scheme: On load mlx5 allocates 4 (for async) + #cores (for data completions) MSIX vectors, mlx5 core will assign 3 MSIX vectors for internal async EQs and will use all of the #cores MSIX vectors for completion EQs, (One vector is going to be reserved for a generic EQ). After this patch an external user (e.g mlx5_ib) of mlx5_core can use this new API to create new generic EQs with the reserved msix vector index for that eq.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* net/mlx5: Use multi threaded workqueue for page fault handlingMoni Shoua2018-11-121-2/+3
| | | | | | | | | | | | | | | | | | | | | Page fault events are processed in a workqueue context. Since each QP can have up to two concurrent unrelated page-faults, one for requester and one for responder, page-fault handling can be done in parallel. Achieve this by changing the workqueue to be multi-threaded. The number of threads is the same as the number of command interface channels to avoid command interface bottlenecks. In addition to multi-threads, change the workqueue flags to give it high priority. Stress benchmark shows that before this change 85% of page faults were waiting in queue 8 seconds or more while after the change 98% of page faults were waiting in queue 64 milliseconds or less. The number of threads was chosen as the number of channels to the command interface.
