crc checksums are used to validate the output. Normally they're part of the actual display hardware but on virtual stack there's nothing to automatically generate them. Implement crc generation for the vmwgfx stack. This works only on screen targets, where it's possibly to easily make sure that the guest side contents of the surface matches the host sides output. Just like the vblank support, crc generation can only be enabled via: guestinfo.vmwgfx.vkms_enable = "TRUE" option in the vmx file. Makes IGT's kms_pipe_crc_basic pass and allows a huge number of other IGT tests which require CRC generation of the output to actually run on vmwgfx. Makes it possible to actually validate a lof of the kms and drm functionality with vmwgfx.

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.
