From c58305af1835095ddc25ee6f548ac05915e66ac5 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 19 Aug 2016 16:54:28 +0100 Subject: drm/i915: Use remap_io_mapping() to prefault all PTE in a single pass Very old numbers indicate this is a 66% improvement when remapping the entire object for fence contention - due to the elimination of track_pfn_insert and its strcmp.
