RDMA/uverbs: Expose the new GID query API to user space

2020-10-02T00:20:11Z

Expose the query GID table and entry API to user space by adding two new methods and method handlers to the device object. This API provides a faster way to query a GID table using single call and will be used in libibverbs to improve current approach that requires multiple calls to open, close and read multiple sysfs files for a single GID table entry.

RDMA/core: Add the core support field to METHOD_GET_CONTEXT

2020-01-16T19:55:46Z

Add the core support field to METHOD_GET_CONTEXT, this field should represent capabilities that are not device-specific. Return support for optional access flags for memory regions. User-space will use this capability to mask the optional access flags for unsupporting kernels.

RDMA/uverbs: Add ioctl command to get a device context

2020-01-16T19:55:45Z

Allow future extensions of the get context command through the uverbs ioctl kabi. Unlike the uverbs version this does not return an async_fd as well, that has to be done with another command.
