---help---
Userspace InfiniBand verbs support. This is the kernel side
of userspace verbs, which allows userspace processes to
directly access InfiniBand hardware for fast-path
operations. You will also need libibverbs and a hardware
driver library from <http://www.openib.org>.
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 <http://www.openib.org>.
config INFINIBAND_USER_ACCESS
tristate "InfiniBand userspace access (verbs and CM)"
depends on INFINIBAND
---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
<http://www.openib.org>.
