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

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>.

"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>.

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.

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

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.
