Updating the Device Firmware Automatically upon System Boot
As of MLNX_OFED v3.1-x.x.x, firmware can be automatically updated upon system boot. The
firmware update package (mlnx-fw-updater) is installed in the "/opt/mellanox/mlnx-fw-updater"
folder, and openibd service script can invoke the firmware update process if requested on boot.
If the firmware is updated, the following message is printed to the system's standard logging file:
fw_updater: Firmware was updated. Please reboot your system
Otherwise, the following message is printed:
fw_updater: Didn't detect
Please note, this feature is disabled by default. To enable the automatic firmware update upon
system boot, set the following parameter to "yes" "RUN_FW_UPDATER_ONBOOT=yes" in the
openibd service configuration file "/etc/infiniband/openib.conf".
You can opt to exclude a list of devices from the automatic firmware update procedure. To do so,
edit the configurations file "/opt/mellanox/mlnx-fw-updater/mlnx-fw-updater.conf" and provide a
comma separated list of PCI devices to exclude from the firmware update.
Example:
MLNX_EXCLUDE_DEVICES="00:05.0,00:07.0"

UEFI Secure Boot

All kernel modules included in MLNX_OFED for RHEL7 and SLES12 are signed with x.509 key to
support loading the modules when Secure Boot is enabled.
Enrolling NVIDIA's x.509 Public Key on Your Systems
In order to support loading MLNX_OFED drivers when an OS supporting Secure Boot boots on a UEFI-
based system with Secure Boot enabled, the NVIDIA x.509 public key should be added to the UEFI
Secure Boot key database and loaded onto the system key ring by the kernel.
