Description: |
|
Get mainboard and BIOS info easily on the Loongson platform, |
|
this is useful to point out the current used mainboard type |
|
and BIOS version when there exists problems related with |
|
hardware or firmware. |
|
|
|
The related structures are already defined in the interface |
|
specification about firmware and kernel which are common |
|
requirement and specific for Loongson64, so only add a new |
|
boardinfo.c file in arch/mips/loongson64. |
|
|
|
For example: |
|
|
|
[loongson@linux ~]$ cat /sys/firmware/lefi/boardinfo |
|

By the way, using dmidecode command can get the similar info if there |
|
exists SMBIOS in firmware, but the fact is that there is no SMBIOS on |
|
some machines, we can see nothing when execute dmidecode, like this: |
|
|
|
[root@linux loongson]# dmidecode |
|
# dmidecode 2.12 |
|
# No SMBIOS nor DMI entry point found, sorry.
