The cpu (de)tiler hw is gone, this stopped being useful. Plus it never supported any of the fancy new tiling formats, which means userspace also stopped using the magic side-channel this provides. This would totally break a lot of the igts, but they're already broken for the same reasons as userspace on gen12 would be. v2: Look at ggtt->num_fences instead, that also avoids the need for a comment (Chris). This also means that gen12 support really needs to make sure num_fences is set to 0. There is a patch for that, but it checks for HAS_MAPPABLE_APERTURE, which I'm not sure is the right thing really.

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 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.
