With gtt remapping in place we can use arbitrarily large framebuffers. Let's bump the limits to 16kx16k on gen7+. The limit was chosen to match the maximum 2D surface size of the 3D engine. With the remapping we could easily go higher than that for the display engine. However the modesetting ddx will blindly assume it can handle whatever is reported via kms. The oversized buffer dimensions are not caught by glamor nor Mesa until finally an assert will trip when genxml attempts to pack the SURFACE_STATE. So we pick a safe limit to avoid the X server from crashing (or potentially misbehaving if the genxml asserts are compiled out).

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.
