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>`.
