This commit introduces "libbnxt_re" version 220.0.5.0 to StarlingX to
support Broadcom NetXtreme-E network adapters' Infiniband/RDMA
functionality. "libbnxt_re" is an Infiniband verbs library.
The source RPM file is used for packaging purposes, and the following
changes are made to source RPM as part of the packaging for StarlingX.
(This is a summary; for further information, please see the patch
files.)
- The spec file is adapted to StarlingX by modifying its Release and
BuildRoot fields.
- For compatibility with StarlingX's build scripts, the whitespace
between the field names and the colon characters (':') are removed.
- A BuildRequires is added for kernel{?bt_ext}-headers >= 5.10 to ensure
that libbnxt_re build does not fail due to a conflict between
rdma-core and kernel-headers-4.18, the latter of which is
pre-installed and stays installed in the mock/chroot file system until
the kernel packages are built by the build system. (This build failure
is a transient issue impacting efficiency, as the build system retries
building the package until the correct kernel headers are installed.)
- The configure script is regenerated to ensure that the newer version
of rdma-core is supported by the configure script, which hard-codes
ABI version v22, whereas StarlingX ships with rdma-core ABI version
v37. This is done by calling the autogen.sh script in %build.
- The original source RPM file replaces pre-existing libbnxt_re library
file symbolic link in /usr/lib64/libibverbs via post-installation
hooks (i.e., %post). This behaviour is modified to instead directly
include the symbolic link in the package, since StarlingX's version of
rdma-core does not include the libbnxt_re library.
- The configure.ac file is patched to use a compatibility version of the
"stdatomic.h" header provided by libbnxt_re, as the StarlingX/CentOS 7
toolchain does not have this header file.
Testing:
- An ISO image is successfully built (monolithically) with this commit.
- This commit has not yet been directly tested due to a lack of
hardware; however, we have confirmed that the library is successfully
dynamically loaded by applications making use of the libibverbs
library by packaging the Linux RDMA community's perftest tools for
StarlingX and then starting the ib_send_bw performance test tool on a
physical server with Mellanox hardware. This was followed by
confirming that the /proc/<PID>/maps file for the ib_send_bw process
contains the new libbnxt_re library. The latter indicates that the
library is successfully loaded.
