Ian Forbes 059b58ef6a drm/vmwgfx: Filter modes which exceed graphics memory 
[ Upstream commit 4268269331 ]

SVGA requires individual surfaces to fit within graphics memory
(max_mob_pages) which means that modes with a final buffer size that would
exceed graphics memory must be pruned otherwise creation will fail.

Additionally llvmpipe requires its buffer height and width to be a multiple
of its tile size which is 64. As a result we have to anticipate that
llvmpipe will round up the mode size passed to it by the compositor when
it creates buffers and filter modes where this rounding exceeds graphics
memory.

This fixes an issue where VMs with low graphics memory (< 64MiB) configured
with high resolution mode boot to a black screen because surface creation
fails.

README 

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.
