Slice/subslice/EU information should be obtained via the topology queries provided by the I915_QUERY interface; let's turn off support for the old GETPARAM lookups on Xe_HP and beyond where we can't return meaningful values. The slice mask lookup is meaningless since Xe_HP doesn't support traditional slices (and we make no attempt to return the various new units like gslices, cslices, mslices, etc.) here. The subslice mask lookup is even more problematic; given the distinct masks for geometry vs compute purposes, the combined mask returned here is likely not what userspace would want to act upon anyway. The value is also limited to 32-bits by the nature of the GETPARAM ioctl which is sufficient for the initial Xe_HP platforms, but is unable to convey the larger masks that will be needed on other upcoming platforms. Finally, the value returned here becomes even less meaningful when used on multi-tile platforms where each tile will have its own masks.

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.
