From 088e0df4020e30c4952f29dc672ceb4742b98e73 Mon Sep 17 00:00:00 2001 From: Michel Thierry Date: Fri, 7 Aug 2015 17:40:17 +0100 Subject: [PATCH] drm/i915/gtt: Allow >= 4GB offsets in X86_32 Similar to commit c44ef60e437019b8ca1dab8b4d2e8761fd4ce1e9 ("drm/i915/gtt: Allow >= 4GB sizes for vm"), i915_gem_obj_offset and i915_gem_obj_ggtt_offset return an unsigned long, which in only 4-bytes long in 32-bit kernels. Change return type (and other related offset variables) to u64. Since Global GTT is always limited to 4GB, this change would not be required in i915_gem_obj_ggtt_offset, but this is done for consistency. v2: Remove unnecessary offset variable in do_pin, as we already have vma->node.start (Chris). Update GGTT offset too (Tvrtko).
