Existing implementation (broken) of IFS used a header format (for IFS test images) which was very similar to microcode format, but didn’t accommodate extended signatures. This meant same IFS test image had to be duplicated for different steppings and the validation code in the driver was only looking at the primary header parameters. Going forward, IFS test image headers have been tweaked to become fully compatible with the microcode format. Newer IFS test image headers will use header version 2 in order to distinguish it from microcode images and older IFS test images. In light of the above, reuse struct microcode_header_intel directly in the IFS driver and reuse microcode functions for validation and sanity checking.

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.
