This commit adds the libbnxt_re Infiniband verbs library to Debian-based
StarlingX.
In comparison to commit 9baff8aa884a ("Introduce libbnxt_re version
220.0.5.0") and commit 4112936362c6 ("libbnxt_re: Add support for
rdma-core v37") that introduce the same library to CentOS-based
StarlingX, the only change in this commit was to remove the use of the
"stdatomic.h" header's compatibility-oriented version shipped with
libbxnt_re. This header file is already provided by Debian's newer
toolchain.
The two patches make the library compatible with rdma-core v37 provided
by Mellanox OFED's version of rdma-core. For further information, please
see commit 4112936362c6 ("libbnxt_re: Add support for rdma-core v37").
Verification notes:
- An ISO image with the standard kernel was successfully built with this
commit and the resulting ISO image was installed onto a physical
server with a quad-port Broadcom NetXtreme-E network adapter, of which
the third and fourth ports were connected to each other with a
loopback cable.
- When we installed the Linux RDMA community's perftest package on
Debian-based StarlingX with apt-get and attempted to run the benchmark
programs, we encountered a dynamically-linked library error caused by
the "libefa.so" Infiniband verbs library (that perftest's utilities
appear to link against) not existing on the system. This occurs
because the Mellanox OFED version of the rdma-core package in
StarlingX does not build the libefa.so library.
To work around this, we built the perftest package in a Debian
Bullseye container, after having modified perftest's configure.ac file
to avoid linking against libefa.so. The resulting binaries were
successfully used on the aforementioned server to verify the
libbnxt_re Infiniband verbs library and the bnxt_re driver.
The test procedure consisted of using a server ib_write_bw instance on
the 3rd port of the network adapter and another instance as a client
on the 4th port of the network adapter. (Recall that ports 3 and 4
were connected to each other.)
- The preempt-rt kernel was not tested due to not being able to generate
a working ISO image that installed onto a virtual machine. (The
installation process was aborted with a kickstart file parse error.)
