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
|
|

BIOS Info

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.
