NAME         top

       mlx5dv_vfio_get_events_fd - Get the file descriptor to manage
       driver events.

SYNOPSIS         top

              #include <infiniband/mlx5dv.h>

              int mlx5dv_vfio_get_events_fd(struct ibv_context *ctx);

DESCRIPTION         top

       Returns the file descriptor to be used for managing driver events.

ARGUMENTS         top

       ctx    device context that was opened for VFIO by calling
              mlx5dv_get_vfio_device_list().

RETURN VALUE         top

       Returns the internal matching file descriptor.

NOTES         top

       Client code should poll the returned file descriptor and once
       there is some data to be managed immediately call
       mlx5dv_vfio_process_events().
