From 894eeecc1e3b47ef115e252ec58eff7ec174e7ef Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 4 Aug 2016 07:52:20 +0100 Subject: [PATCH] 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.
