RDMA/uverbs: Add support for UCAPs in context creation

2025-03-09T17:13:02Z

Add support for file descriptor array attribute for GET_CONTEXT commands. Check that the file descriptor (fd) array represents fds for valid UCAPs. Store the enabled UCAPs from the fd array as a bitmask in ib_ucontext.

RDMA: Pass entire uverbs attr bundle to create cq function

2024-06-27T19:28:21Z

Changes the create_cq verb signature by sending the entire uverbs attr bundle as a parameter. This allows drivers to send driver specific attrs through ioctl for the create_cq verb and access them in their driver specific code. Also adds a new enum value for driver specific ioctl attributes for methods already supporting UHW.

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.
