| SMBIOS tables |
| ============= |
| |
| The System Management BIOS (SMBIOS) table is used to deliver management |
| information from the firmware to the operating system. The content is |
| standardized in [1]_. |
| |
| In Linux you can use the dmidecode command to view the contents of the SMBIOS |
| table. |
| |
| When booting via UEFI the SMBIOS table is transferred as an UEFI configuration |
| table to the operating system. |
| |
| To generate SMBIOS tables in U-Boot, the CONFIG_GENERATE_SMBIOS_TABLE option |
| must be enabled. The easiest way to provide the values to use is via the device |
| tree. For details see |
| :download:`smbios.txt <../device-tree-bindings/sysinfo/smbios.txt>`. |
