Extend systems of class VMOD0010 equipped with CoffeeLake COMEx module with BIOS related attributes to represent various BIOS statuses. These attributes "bios_active_image", "bios_auth_fail", "bios_upgrade_fail", "bios_safe_mode" has been already added to modular system. This all of them are already documented. - "bios_active_image" - location of current active BIOS image (0: Top, 1: Bottom. The reported value should correspond to value expected by OS in case of BIOS safe mode is 0. This bit is related to Intel top-swap feature of DualBios on the same flash. - "bios_auth_fail": BIOS upgrade is failed because provided BIOS image is not signed correctly. - "bios_upgrade_fail" BIOS upgrade is failed by some reason not related to authentication. For example, due to physical SPI flash problem. - "bios_safe_mod": - 0 : if BIOS is booted from a supposed active image; 1 : BIOS safe mechanism was enforced by hardware (CPLD).

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.
