RDMA/uverbs: Make UVERBS_OBJECT_METHODS to consider line number

2021-04-13T22:36:35Z

In order to support multiple methods declaration in the same file we should use the line number as part of the name. Link: https://lore.kernel.org/r/20210411122924.60230-3-leon@kernel.org Signed-off-by: Maor Gottlieb Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/include: Replace license text with SPDX tags

2020-07-29T17:48:36Z

The header files in RDMA subsystem are dual licensed and can be described by simple SPDX tag, so replace all of them at once together with making them use the same coding style for header guard defines.

RDMA/core: Make the entire API tree static

2020-01-30T20:28:52Z

Compilation of mlx5 driver without CONFIG_INFINIBAND_USER_ACCESS generates the following error. on x86_64: ld: drivers/infiniband/hw/mlx5/main.o: in function `mlx5_ib_handler_MLX5_IB_METHOD_VAR_OBJ_ALLOC': main.c:(.text+0x186d): undefined reference to `ib_uverbs_get_ucontext_file' ld: drivers/infiniband/hw/mlx5/main.o:(.rodata+0x2480): undefined reference to `uverbs_idr_class' ld: drivers/infiniband/hw/mlx5/main.o:(.rodata+0x24d8): undefined reference to `uverbs_destroy_def_handler' This is happening because some parts of the UAPI description are not static. This is a hold over from earlier code that relied on struct pointers to refer to object types, now object types are referenced by number. Remove the unused globals and add statics to the remaining UAPI description elements. Remove the redundent #ifdefs around mlx5_ib_*defs and obsolete mlx5_ib_get_devx_tree(). The compiler now trims alot more unused code, including the above problematic definitions when !CONFIG_INFINIBAND_USER_ACCESS.

RDMA/uverbs: Fix typo in string concatenation macro

2018-12-07T04:11:06Z

Update UVERBS_OBJECT() macro to properly concatenate the object name. Fixes: e502a864c352 ("IB/core: Introduce DECLARE_UVERBS_GLOBAL_METHODS") Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/uverbs: Use a linear list to describe the compiled-in uapi

2018-11-22T18:57:32Z

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.

IB/mlx5: Introduce driver create and destroy flow methods

2018-07-24T20:03:49Z

Introduce driver create and destroy flow methods on the uverbs flow object. This allows the driver to get its specific device attributes to match the underlay specification while still using the generic ib_flow object for cleanup and code sharing. The IB object's attributes are set via the ib_set_flow() helper function. The specific implementation for the given specification is added in downstream patches.

RDMA/uverbs: Get rid of the & in method specifications

2018-07-04T19:47:01Z

Hide it inside the macros. The & is confusing and interferes with using this as a generic DSL in later patches. Since this also touches almost every line, also run the specs through clang-format (with 'BinPackParameters: false') to make the maintenance easier.

RDMA/uverbs: Simplify UVERBS_OBJECT and _TREE family of macros

2018-07-04T19:47:01Z

Instead of the large set of indirecting macros, define the few needed macros to directly instantiate the struct uverbs_oject_tree_def and associated objects list. This is small amount of code duplication but the readability is far better. Signed-off-by: Jason Gunthorpe Signed-off-by: Leon Romanovsky

IB/core: Introduce DECLARE_UVERBS_GLOBAL_METHODS

2018-06-19T16:53:02Z

Introduce a new macro to be used for global methods on a singleton object. This macros sets internally the type_attrs to be NULL as such an object can't be created. Downstream patches from this series will use this macro. Signed-off-by: Yishai Hadas Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe
