From: Chris Wilson Date: Thu, 4 Aug 2016 06:52:20 +0000 (+0100) Subject: drm/i915: Amalgamate GGTT/ppGTT vma debug list walkers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=894eeecc1e3b47ef115e252ec58eff7ec174e7ef;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Amalgamate GGTT/ppGTT vma debug list walkers As we can now have multiple VMA inside the global GTT (with partial mappings, rotations, etc), it is no longer true that there may just be a single GGTT entry and so we should walk the full vma_list to count up the actual usage. In addition to unifying the two walkers, switch from multiplying the object size for each vma to summing the bound vma sizes.
