2018-11-22RDMA/uverbs: Use a linear list to describe the compiled-in uapiJason Gunthorpe12-163/+183
The 'tree' data structure is very hard to build at compile time, and this makes it very limited. The new radix tree based compiler can handle a more complex input language that does not require the compiler to perfectly group everything into a neat tree structure. Instead use a simple list to describe to input, where the list elements can be of various different 'opcodes' instructing the radix compiler what to do. Start out with opcodes chaining to other definition lists and chaining to the existing 'tree' definition. Replace the very top level of the 'object tree' with this list type and get rid of struct uverbs_object_tree_def and DECLARE_UVERBS_OBJECT_TREE.

2018-11-22RDMA/mlx5: Do not generate the uabi specs unconditionallyJason Gunthorpe1-8/+9
For DM there is no reason not to add the spec for the START_OFFSET, if DM is not supported then ib_dev.alloc_dm is already set to NULL which ensures we do not call the method. For IPSEC, the core code should be setting ib_dev.create_flow_action_esp to NULL to disable it, not relying on wonky manipulation of the specs.

Add mlx5_eq_{create/destroy}_generic APIs and EQE access methods, for mlx5 core consumers generic EQs. 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.

2018-11-20net/mlx5: EQ, Different EQ typesSaeed Mahameed10-199/+270
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.

2018-11-12net/mlx5: Use multi threaded workqueue for page fault handlingMoni Shoua1-2/+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.

When page fault event for a WQE arrives, the event data contains the resource (e.g. QP) number which will later be used by the page fault handler to retrieve the resource. Meanwhile, another context can destroy the resource and cause use-after-free. To avoid that, take a reference on the resource when handler starts and release it when it ends. Page fault events for RDMA operations don't need to be protected because the driver doesn't need to access the QP in the page fault handler.
