Bug ID: 211761
Summary: Add Infiniband (WITH_OFED) support to default
buildworld
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: freebsd-b...@freebsd.org
Reporter: bacon4...@gmail.com
CC: freebsd-amd64@FreeBSD.org

I'm wondering if it would be possible to add OFED support to the default
userland tools in the near future.
Note: I am NOT suggesting adding Infiniband (IB) drivers to the generic kernel,
which I think would be too risky.
Currently, adding IB support to the kernel can be done via either a buildkernel
or by building kernel modules, a very quick and easy process:
https://wiki.freebsd.org/InfiniBand
Adding support to the userland tools still requires a buildworld as far as I
have been able to determine. This is a major obstacle for mass deployment of
IB-enabled systems, such as compute nodes in an HPC cluster. It's a lengthy
process that could be undone by certain freebsd-update patches, resulting in
additional down time following updates.
I don't believe that enabling OFED support in the userland without enabling the
IB drivers poses any serious risk, and with the availabilty of kernel modules
for the IB drivers, it would allow for rapid deployment and easy maintenance of
IB-enabled FreeBSD systems.
Thanks,
Jason
