[ Upstream commit 5a213086a025349361b5cf75c8fd4591d96a7a99 ] Several workarounds are guarded by IS_MTL_GRAPHICS_STEP. However none of these workarounds are actually tied to MTL as a platform; they only relate to the Xe_LPG graphics IP, regardless of what platform it appears in. At the moment MTL is the only platform that uses Xe_LPG with IP versions 12.70 and 12.71, but we can't count on this being true in the future. Switch these to use a new IS_GFX_GT_IP_STEP() macro instead that is purely based on IP version. IS_GFX_GT_IP_STEP() is also GT-based rather than device-based, which will help prevent mistakes where we accidentally try to apply Xe_LPG graphics workarounds to the Xe_LPM+ media GT and vice-versa. v2: - Switch to a more generic and shorter IS_GT_IP_STEP macro that can be used for both graphics and media IP (and any other kind of GTs that show up in the future). v3: - Switch back to long-form IS_GFX_GT_IP_STEP macro. (Jani) - Move macro to intel_gt.h. (Andi) v4: - Build IS_GFX_GT_IP_STEP on top of IS_GFX_GT_IP_RANGE and IS_GRAPHICS_STEP building blocks and name the parameters from/until rather than begin/fixed. (Jani) - Fix usage examples in comment. v5: - Tweak comment on macro.

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.
