Although some of our Xe_LPG workarounds were already being applied based on IP version correctly, others were matching on MTL as a base platform, which is incorrect. Although MTL is the only platform right now that uses Xe_LPG IP, this may not always be the case. If a future platform re-uses this graphics IP, the same workarounds should be applied, even if it isn't a "MTL" platform. We were also incorrectly applying Xe_LPG workarounds/tuning to the Xe_LPM+ media IP in one or two places; we should make sure that we don't try to apply graphics workarounds to the media GT and vice versa where they don't belong. A new helper macro IS_GT_IP_RANGE() is added to help ensure this is handled properly -- it checks that the GT matches the IP type being tested as well as the IP version falling in the proper range. Note that many of the stepping-based workarounds are still incorrectly checking for a MTL base platform; that will be remedied in a later patch. v2: - Rework macro into a slightly more generic IS_GT_IP_RANGE() that can be used for either GFX or MEDIA checks. v3: - Switch back to separate macros for gfx and media. (Jani) - Move macro to intel_gt.h.

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.
