Is there any tools/applications to validate Non-Transparent Bridge (NTB) functions?

Rajesh Kumar
Hi,

Does anyone have any prior experience working on NTB driver in FreeBSD? If
so, do we have any tools/applications to verify the NTB driver functions.
In Linux, there are tools like ntb_perf, ntb_pingpong, ntb_tool for various
purposes. Do we have any equivalent in FreeBSD?

Thanks,
Rajesh.

Looks like you can try to bring up an interface on them to connect
the two:
https://www.freebsd.org/cgi/man.cgi?query=if_ntb&sektion=4&manpath=FreeBSD+11.2-RELEASE+and+Ports

There are various links to other manpages talking about how to use
them...

Thanks John, Sorry about the so late response.

I could use the if_ntb driver to verify the ntb functions. I could able to
ping between the ntb interfaces. Is there any way, we can measure the
performance of the NTB transactions in FreeBSD. Like we have the ntb_perf
driver in Linux, is there any other generic tool which can be used in
FreeBSD?
