I'd keep using begin-end or from-until instead of begin-fixed. This
check should really agnostic about issues that get fixed.
We have macros for checking step ranges, e.g. IS_GRAPHICS_STEP(i915,
since, util). They should be used instead of duplicating the
condition. And in the previous patch you added IS_GFX_GT_IP_RANGE()
which is also pretty much duplicated here?
But the stepping check is really orthogonal from the other conditions. I
was hoping to replace the IS_MTL_GRAPHICS_STEP() and friends macros with
IS_METEORLAKE() && IS_GRAPHICS_STEP() combos, because there's nothing
that requires us to keep adding new macros for these.
Of course, with the IP check there's no need to add new platform
specific macros... but is there a need to combine all these together?
