RE: Need information about understanding PCIE non-transparent bridge

["Allen Hubbe" <Allen.Hubbe@emc.com>]

Hi Sridhar,

If you have NTB hardware already physically connected and
configured in your BIOS, then you can build and load the
linux ntb modules.

Here is the documentation on linux ntb modules.  It says
what the modules do, and how to use them.

http://lxr.free-electrons.com/source/Documentation/ntb.txt

If you are interested in testing or demonstrating basic NTB
functionality, try ntb_tool and ntb_pingpong.  There is
also a network device over NTB supported by ntb_transport
and ntb_netdev together.

Please let me know if you have any questions not answered in
the documentation.  I am happy to help.

Allen
