Linux kernel stable tree
6c1bfbd9df
Add /sys/firmware/lefi/boardinfo to 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. E.g. with this patch: [loongson@linux ~]$ cat /sys/firmware/lefi/boardinfo Board Info Manufacturer : LEMOTE Board Name : LEMOTE-LS3A4000-7A1000-1w-V01-pc Family : LOONGSON3 BIOS Info Vendor : Kunlun Version : Kunlun-A1901-V4.1.3-20200414093938 ROM Size : 4 KB Release Date : 2020-04-14 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
