| Firmware Versions |
| ----------------- |
| |
| fbnic has three components stored on the flash which are provided in one PLDM |
| image: |
| |
| 1. fw - The control firmware used to view and modify firmware settings, request |
| firmware actions, and retrieve firmware counters outside of the data path. |
| This is the firmware which fbnic_fw.c interacts with. |
| 2. bootloader - The firmware which validate firmware security and control basic |
| operations including loading and updating the firmware. This is also known |
| as the cmrt firmware. |
| 3. undi - This is the UEFI driver which is based on the Linux driver. |
| |
| fbnic stores two copies of these three components on flash. This allows fbnic |
| to fall back to an older version of firmware automatically in case firmware |
| fails to boot. Version information for both is provided as running and stored. |
| The undi is only provided in stored as it is not actively running once the Linux |
| driver takes over. |
| |
| devlink dev info provides version information for all three components. In |
| addition to the version the hg commit hash of the build is included as a |
| separate entry. |
