From: Chris Wilson Date: Fri, 31 Oct 2014 13:53:53 +0000 (+0000) Subject: drm/i915: Request PIN_GLOBAL when pinning a vma for GTT relocations X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c826c4493851913e57dd47a7fbfe07156ac9f91d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Request PIN_GLOBAL when pinning a vma for GTT relocations Always require PIN_GLOBAL when we want a mappable offset (PIN_MAPPABLE). This causes the pin to fixup the global binding in cases were the vma was already bound (and due to the proceeding bug, we considered it to be already mappable).
