We add two 3x4 matrices into the VKMS color pipeline. The reason we're adding matrices is so that we can test that application of a matrix and its inverse yields an output equal to the input image. One complication with the matrix implementation has to do with the fact that the matrix entries are in signed-magnitude fixed point, whereas the drm_fixed.h implementation uses 2s-complement. The latter one is the one that we want for easy addition and subtraction, so we convert all entries to 2s-complement.

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 reStructuredText 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.
