This driver was first merged over 10 years ago and has not seen major activity by the authors in the last 7 years. However, in that time it has been patched 150 times to adapt it to changing kernel APIs. Further, the hardware has several issues, like not supporting 64 bit DMA, that make it rather uninteresting for use with modern systems and RDMA.

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

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>.

IOCTL based uAPI support for Infiniband is enabled by default for

for current legacy verbs too.

On demand paging support for the InfiniBand subsystem.

memory regions without pinning their pages, fetching the

pages on demand instead.
