11	  any protocols you wish to use as well as drivers for your
12	  InfiniBand hardware.

17	tristate "InfiniBand userspace MAD support"
18	depends on INFINIBAND
19	---help---
20	  Userspace InfiniBand Management Datagram (MAD) support.  This
21	  is the kernel side of the userspace MAD support, which allows
22	  userspace processes to send and receive MADs. You will also
23	  need libibumad from rdma-core
24	  <https://github.com/linux-rdma/rdma-core>.

30	---help---
31	  Userspace InfiniBand access support.  This enables the
32	  kernel side of userspace verbs and the userspace
33	  communication manager (CM).  This allows userspace processes
34	  to set up connections and directly access InfiniBand
35	  hardware for fast-path operations.  You will also need
36	  libibverbs, libibcm and a hardware driver library from
37	  rdma-core <https://github.com/linux-rdma/rdma-core>.

41	depends on BROKEN || COMPILE_TEST
42	depends on INFINIBAND_USER_ACCESS
43	help
44	  The UCM module has known security flaws, which no one is
45	  interested to fix. The user-space part of this code was
46	  dropped from the upstream a long time ago.
47
48	  This option is DEPRECATED and planned to be removed.

50config INFINIBAND_EXP_LEGACY_VERBS_NEW_UAPI
51	bool "Allow experimental legacy verbs in new ioctl uAPI  (EXPERIMENTAL)"
52	depends on INFINIBAND_USER_ACCESS
53	---help---
54	  IOCTL based uAPI support for Infiniband is enabled by default for
55	  new verbs only. This allows userspace to invoke the IOCTL based uAPI
56	  for current legacy verbs too.

65	bool "InfiniBand on-demand paging support"
66	depends on INFINIBAND_USER_MEM
67	select MMU_NOTIFIER
68	default y
69	---help---
70	  On demand paging support for the InfiniBand subsystem.
71	  Together with driver support this allows registration of
72	  memory regions without pinning their pages, fetching the
73	  pages on demand instead.
74
75config INFINIBAND_ADDR_TRANS
76	bool "RDMA/CM"
77	depends on INFINIBAND
78	default y
79	---help---
80	  Support for RDMA communication manager (CM).
81	  This allows for a generic connection abstraction over RDMA.
82
83config INFINIBAND_ADDR_TRANS_CONFIGFS
84	bool
85	depends on INFINIBAND_ADDR_TRANS && CONFIGFS_FS && !(INFINIBAND=y && CONFIGFS_FS=m)
86	default y
87	---help---
88	  ConfigFS support for RDMA communication manager (CM).
89	  This allows the user to config the default GID type that the CM
90	  uses for each device, when initiaing new connections.
