[Intel-gfx] [PATCH 3/8] drm/i915: Eliminate IS_MTL_GRAPHICS_STEP
Matt Roper

Tue Jul 18 22:27:57 UTC 2023
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_IPVER_STEP() macro instead
that is purely based on IP version. IS_GFX_IPVER_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.
