drm/xe/compat: remove i915_vma.h from compat 2026-03-03T14:05:58+00:00 Jani Nikula jani.nikula@intel.com 2026-02-27T17:17:13+00:00 cb0f3a171f197325f0831d7d9b0c5388dae0608f Move compat i915_vma.h to xe_display_vma.h, and remove all extra cruft. Drop the i915_ggtt_offset() wrapper in favour of using xe_ggtt_node_addr() directly. The usefulness of the I915_TILING_X and I915_TILING_Y undef/define is unclear, since uapi/drm/i915_drm.h is included in other paths as well. The naming of struct i915_vma is a bit unfortunate in xe, but (at least for now) a necessity for maintaining type safety on the opaque type.
