From: Jani Nikula Date: Mon, 24 Feb 2025 16:00:49 +0000 (+0200) Subject: drm/i915: split out i915_gtt_view_types.h from i915_vma_types.h X-Git-Tag: block-6.15-20250403~41^2~9^2~57 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=767bb0b172fcfe62000265c91c4a84837d2428a7;p=linux-block.git drm/i915: split out i915_gtt_view_types.h from i915_vma_types.h In the interest of limiting the display dependencies on i915 core headers, split out i915_gtt_view_types.h from i915_vma_types.h, and only include the new header from intel_display_types.h. Reuse the new header from xe compat code too, failing build if partial view is used in display code. Side note: Why would we ever have set enum i915_gtt_view_type values to size of each type?! What an insane hack.
