  	help

  	  Userspace InfiniBand Management Datagram (MAD) support.  This
  	  is the kernel side of the userspace MAD support, which allows

  	  userspace processes to send and receive MADs. You will also

  	  need libibumad from rdma-core
  	  <https://github.com/linux-rdma/rdma-core>.

  
  config INFINIBAND_USER_ACCESS
  	tristate "InfiniBand userspace access (verbs and CM)"

  	depends on MMU

  	help

  	  Userspace InfiniBand access support.  This enables the
  	  kernel side of userspace verbs and the userspace
  	  communication manager (CM).  This allows userspace processes
  	  to set up connections and directly access InfiniBand
  	  hardware for fast-path operations.  You will also need
  	  libibverbs, libibcm and a hardware driver library from

  	  rdma-core <https://github.com/linux-rdma/rdma-core>.

  	help

  	  On demand paging support for the InfiniBand subsystem.
  	  Together with driver support this allows registration of
  	  memory regions without pinning their pages, fetching the
  	  pages on demand instead.

  config INFINIBAND_ADDR_TRANS

  	bool "RDMA/CM"

  	depends on INFINIBAND

  	default y

  	help

  	  Support for RDMA communication manager (CM).
  	  This allows for a generic connection abstraction over RDMA.

  	default y

  	help

  	  ConfigFS support for RDMA communication manager (CM).
  	  This allows the user to config the default GID type that the CM
  	  uses for each device, when initiaing new connections.
