Stepping-specific media behavior shouldn't be tied to MTL as a platform, but rather specifically to the Xe_LPM+ IP. Future non-MTL platforms may re-use this IP and will need to follow the exact same logic and apply the same workarounds. IS_MTL_MEDIA_STEP() is dropped in favor of IS_MEDIA_GT_IP_STEP, which checks the media IP version associated with a specific IP and also ensures that we're operating on the media GT, not the primary GT. v2: - Switch to the IS_GT_IP_STEP macro. v3: - Switch back to long-form IS_MEDIA_GT_IP_STEP. (Jani) v4: - Build IS_MEDIA_GT_IP_STEP on top of IS_MEDIA_GT_IP_RANGE and IS_MEDIA_STEP building blocks and name the parameters from/until rather than begin/fixed.. (Jani) v5: - Tweak macro comment wording. (Gustavo) - Add a check to catch NULL gt in IS_MEDIA_GT_IP_RANGE; this allows it to be used safely on i915->media_gt, which may be NULL on some platforms.

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.
