---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)"
|
---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
|
The UCM module has known security flaws, which no one is
|
interested to fix. The user-space part of this code was
|
dropped from the upstream a long time ago.
|
|
This option is DEPRECATED and planned to be removed.

config INFINIBAND_EXP_LEGACY_VERBS_NEW_UAPI

depends on INFINIBAND_USER_ACCESS
|
---help---
|
IOCTL based uAPI support for Infiniband is enabled by default for
|
new verbs only. This allows userspace to invoke the IOCTL based uAPI
|
for current legacy verbs too.

---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

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.
