[Intel-gfx] [PATCH v2 9/9] drm/i915: Replace several IS_METEORLAKE with proper IP version checks
Matt Roper

Tue Jul 25 00:13:22 UTC 2023
Many of the IS_METEORLAKE conditions throughout the driver are supposed
to be checks for Xe_LPG and/or Xe_LPM+ IP, not for the MTL platform
specifically. Update those checks to ensure that the code will still
operate properly if/when these IP versions show up on future platforms.
v2:
- Add comment to i915_coherent_map_type() noting that the current
implementation of the workaround is too broad. (Tvrtko)
