Updating firmware based on firmware stability index

An apparatus, the apparatus being a baseboard management controller (BMC), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, at the BMC, an update package containing one or more updated software components of a firmware image of the BMC to replace corresponding existing software components running on the BMC;
• shut down the corresponding existing software components running on the BMC and execute the one or more updated software components of the firmware image of the BMC;
• calculate one or more first stability factors of the one or more updated software components of the firmware image of the BMC;
• compare the one or more first stability factors of the one or more updated software components of the firmware image of the BMC with one or more second stability factors of the corresponding existing software components running on the BMC;
• determine whether to keep the one or more updated software components of the firmware image of the BMC based on the comparison result;
• and
• when the comparison result indicates that the one or more updated software components of the firmware image of the BMC are not less stable than the corresponding existing software components running on the BMC, remove the corresponding existing software components running on the BMC from the BMC.

A non-transitory computer-readable medium storing computer executable code for updating firmware in a baseboard management controller (BMC), comprising code configured to:

• receive, at the BMC, an update package containing one or more updated software components of a firmware image of the BMC to replace corresponding existing software components running on the BMC;
• shut down the corresponding existing software components running on the BMC and execute the one or more updated software components of the firmware image of the BMC;
• calculate one or more first stability factors of the one or more updated software components of the firmware image of the BMC;
• compare the one or more first stability factors of the one or more updated software components of the firmware image of the BMC with one or more second stability factors of the corresponding existing software components running on the BMC;
• determine whether to keep the one or more updated software components of the firmware image of the BMC based on the comparison result;
• and
• when the comparison result indicates that the one or more updated software components of the firmware image of the BMC are not less stable than the corresponding existing software components running on the BMC, remove the corresponding existing software components running on the BMC from the BMC.
