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

Matt Roper matthew.d.roper at intel.com
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)
